The effect of a Schema-based method on correcting persistent errors in mental arithmetic: an experimental study.

Introduction: Arithmetic calculation is a fundamental skill for mathematical learning and daily life. However, elementary school students often make errors in practice. Methods: Grounded in the schema theory and the memory retrieval theory of mental arithmetic, this study employs a controlled experiment to investigate the effect of a schema-based method in correcting persistent errors in mental arithmetic, specifically in the context of simple addition operations. The experimental group utilizes a schema-based method to help participants rectify incorrect answers in memory retrieval, while the control group did not receive this treatment. Results: The results showed that significant differences emerged between the experimental and control groups in both the post-test performance and the reduction of persistent error count, indicating that the experimental group had rectified incorrect answers in memory; and persistent errors in simple addition were indeed caused by interference from incorrect answers during memory retrieval; and the schema-based method proves to be effective. Discussion: The findings of this study contribute to enhancing practical mental arithmetic instruction, assisting students in correcting relevant errors, and improving their mental arithmetic abilities. Not only does it offer directive guidance for teaching practices, but it also provides an enlightening reference for promoting innovative teaching methods.

Reliability and validity of simple Chinese version of grit scale for elementary school students.

BACKGROUND: The Grit scale (GS-12) is a widely used rating scale that assess passion and perseverance. The present study aimed to evaluate the reliability and validity of simple Chinese Version of Grit Scale (GS-SC) among Chinese adolescents. METHODS: Seven hundred one primary school students were recruited as Sample 1. Item analysis and exploratory factor analysis (EFA) were conducted on Sample 1 to preliminarily examine the structure of the scale. Sample 2 consisted of 5,384 primary school students. Confirmatory factor analysis (CFA) and verification of reliability and validity were conducted on Sample 2 to establish a formal scale and further verify the psychometric properties by applying item response theory (IRT). RESULTS: EFA and CFA revealed a clear two-factor structure. The results demonstrated that the Simplified Chinese Version of Grit Scale had adequate internal consistency and re-test reliability. GS-CS also showed good criterion-validity with personality, self-control, effort regulation and academic achievement. Furthermore, all the items show a acceptable fit to the GRM and have good discrimination (ranging from 2.13 to 3.45) and moderate difficulty(ranging from-1.58 to 0.95). CONCLUSIONS: The reliability and validity of the GS-SC are good, indicating that the scale can be used as an effective tool for measuring the grit of primary school students in China.

Differences in walking and running parameters in elementary school students with and without backpacks.

BACKGROUND: Backpack syndrome (BS) is a term used to describe symptoms such as shoulder and back pain that are believed to be caused by carrying a backpack. Few studies have investigated the changes in walking and running parameters with and without backpacks. OBJECTIVE: The present study aimed to investigate the differences in walking and running parameters with and without backpacks in primary school children with and without BS. METHODS: This cross-sectional study included 51 children (average age 9.3 years, 6- 12 years). Two questions were asked beforehand: whether the respondents had shoulder or back pain when going to school and present; those who answered that they had pain in both cases were defined as the BS group, while the others were the control group. Walking and running at comfortable speeds and walking and running with a 6 kg backpack on their backs were measured. RESULTS: During walking, there were main effects for speed, cadence, and strike angle with and without the backpack, but no interactions were identified for any of the parameters. In running, however, there were main effects for speed, stride length, strike angle, and lift-off angle, and an interaction effect was observed for speed and stride length. CONCLUSIONS: During walking, carrying a 6 kg backpack increased cadence and walking speed. During running, carrying a backpack caused a decrease in stride length and running speed in the BS group, whereas there was no change in the control group, suggesting that the control and BS groups may respond differently.

The role of handwriting in English word acquisition among elementary students.

In order to investigate whether handwriting has an advantage in learning word form, sound, and meaning, this study randomly selected 40 elementary school student participants (20 males, 20 females, aged 11.4 ± 1.34 years). Using an experimental approach, we compared the learning outcomes of word sound matching, word meaning matching, and word form judgment tasks under two conditions: handwriting and visual learning. After three consecutive days of learning and testing, we found that handwriting generally outperformed visual learning in terms of accuracy and response time in word form, sound, and meaning learning. Additionally, we observed differences in the timing of significant discrepancies in learning outcomes between the two methods across the three tasks. Specifically, in terms of accuracy, discrepancies first appeared in the word sound matching task on the first day, followed by the word form judgment task, and lastly the word meaning matching task. Regarding response time, significant differences between learning methods first emerged in the word form judgment task, followed by the word sound and word meaning tasks. Thus, combining accuracy and response time data, we conclude that handwriting is more advantageous than visual learning for word acquisition, with a differential impact on word form, sound, and meaning, where word form and sound are prioritized over meaning.

The effect of student-perceived teacher support on math anxiety: chain mediation of teacher-student relationship and math self-efficacy.

Introduction: This study investigates the mechanisms linking students' perceived teacher support with math anxiety, focusing on the mediating roles of the teacher-student relationship and mathematics self-efficacy. Methods: The research was conducted with 401 fifth-grade students in China, utilizing scales for Students' Perceived Teacher Support, Teacher-Student Relationship, Math Self-Efficacy, and Math Anxiety. Results: Findings revealed that student-perceived math teacher support, teacher-student relationship, and math self-efficacy were all significantly negatively correlated with math anxiety. It was notably found that student-perceived math teacher support influenced math anxiety through the chain mediation of teacher-student relationship and math self-efficacy. Additionally, the effect of students' perceived emotional support from math teachers on math anxiety, mediated by teacher-student relationship intimacy, was significant only among male students. Discussion: These results underscore the importance of fostering positive teacher-student interactions and enhancing self-efficacy to reduce math anxiety among primary school students. The gender-specific findings regarding emotional support and relationship intimacy highlight the need for tailored strategies in addressing math anxiety.

The Joint Operations of Teacher-Student and Peer Relationships on Classroom Engagement among Low-Achieving Elementary Students: A Longitudinal Multilevel Study.

Although both teacher-student relationship (TSR) and peer relationship (PR) have been found important for the development of students' classroom engagement, little research has been done regarding the joint operations of these two factors. Guided by a developmental systems framework, this study examined longitudinal between-person and within-person associations between TSR/ PR and classroom engagement in a sample of 784 low-achieving students in the first three years of elementary school. A multidimensional approach was used to distinguish positive and negative dimensions of TSR, as well as peer liking and disliking. At the between-person level, results showed that students' classroom engagement was positively predicted by positive TSR and PR liking and was negatively predicted by negative TSR and PR disliking. Both positive and negative TSR interacted with PR disliking at the between-person level, such that the associations between positive/negative TSR and classroom engagement were stronger for students with lower levels of PR disliking. At the within-person level, changes in classroom engagement were associated with contemporaneous year-to-year changes in positive/negative TSR and PR disliking. No within-person level interaction effects were found. Cross-level interaction showed that the effects of within-person negative TSR on classroom engagement were stronger for students with lower overall levels of PR disliking. Findings highlighted the importance of using a multilevel multidimensional approach to understand the joint operations of TSR and PR in the development of classroom engagement in low-achieving students in early elementary school.

The Prevalence of Central Auditory Processing Disorder in Elementary School Students of Kerman, Iran.

Objectives: This study aimed to determine the prevalence of central auditory processing disorder (CAPD) in elementary school students in Kerman, Iran, during 2018-2019. Materials & Methods: This cross-sectional study was conducted on 1369 elementary school students in Kerman. These students were selected by cluster sampling from different areas of Kerman and then screened using the Buffalo Model Questionnaire (BMQ). Based on the data obtained from the questionnaire, normal children were excluded from the study. Then, children with suspected central auditory processing disorder (CAPD) underwent ear exams and were excluded from the study in case of abnormal results in the tympanic membrane examination (rapture-effusion). The remaining subjects underwent peripheral audiometry evaluation, and children with abnormal audiometry were excluded from the study. Finally, the remaining children with suspicious screening results, a normal examination, and normal audiometry underwent a specific test to detect Central auditory processing disorder. Data analysis was carried out using SPSS software. Results: One thousand three hundred sixty-nine primary school students with a mean age of 9.15 ±2.63 years enrolled in this study. 52%% of students were male. 8.03% of them had CAPD. A statistically significant relationship was found between the prevalence of CAPD and gender (P<0.001), place of residence (P<0.001), history of middle ear inflammation (P<0.001) and history of head injury. Conclusion: The quality of life of these students with CAPD can be improved via timely recognition of CAPD and the provision of appropriate preventive and therapeutic facilities.

A comparative study on the development of Chinese and English abilities of Chinese primary school students through two bilingual reading modes: human-AI robot interaction and paper books.

To address the challenges encountered by Chinese primary school students, particularly left-behind and migrant children, who exhibit a preference for animations, video games, and short videos over reading books and struggle with Chinese-English bilingual skills, this study introduces an educational robot AI-assisted method for simultaneous bilingual reading. To assess the effectiveness of this method, a 6-month Chinese-English bilingual extracurricular reading comparative experiment was conducted involving 85 grade 5 students from two classes in a primary school in Hangzhou, China. The AI-assisted class freely read 100 bilingual/English electronic picture books and 200 Chinese electronic classic serial picture books by employing the AI-assisted human-computer interactive electronic reading mode of the "Educational Robot+Audio Electronic Picture Book+Character-play Based Reading." In contrast, the paper book group read the same content presented in the traditional paper book format, following the "regular independent reading" mode. Post-experimental analyses were conducted employing t-tests and MANCOVA and the results revealed that: the primary factors influencing reading effectiveness are the choice of reading materials, reading tools, and reading mode, while reading time does not emerge as the principal influencing factor. Furthermore, students in the AI class demonstrated significant enhancements in bilingual reading motivation, reading amount, reading comprehension, independent learning ability, pronunciation proficiency, and test scores compared to their peers in the paper book class. The AI-assisted reading mode utilizing educational robots garnered positive feedback from teachers, parents, and students. It offers the potential to effectively substitute parental involvement in parent-child reading and English tutoring, while also enabling the simultaneous acquisition of bilingual proficiency in both Chinese and English. This approach proves to be highly effective, cost-efficient, and convenient, particularly for enhancing children's foreign language abilities. Moreover, it fosters positive reading habits and independent learning skills among primary school students, contributes to the establishment of lofty aspirations, and enhances bilingual performance. Overall, this innovative mode offers an effective means of facilitating children's acquisition of bilingualism and foreign language skills, as well as promoting reading education.

Teachers' perspectives of utilizing distance learning to support 21st century skill attainment for K-3 elementary students during the COVID-19 pandemic era.

During the COVID-19 pandemic, Saudi Arabia, similar to other governments, discontinued face-to-face learning in favor of distance learning. The pandemic has had serious ramifications for K-3 education, and the impact of distance learning on 21st century skill attainment are important issues to explore. Using the Saudi Arabia context, this paper investigates teachers' perspectives regarding the implementation of online education to support 21st century skills in the COVID-19 pandemic era for K-3 elementary school students. A qualitative research methodology was applied in this study. A semi-structured interview was conducted to collect data from five K-3 female teachers who implemented online education during the pandemic. Three themes emerged from the findings: 1) effects of the pandemic as related to online teaching for attainment of 21st century skills, 2) elaboration of best practices for online teaching to facilitate such attainment, and 3) challenges that exist for distance learning and student acquisition of 21st century skills. Therefore, the findings suggest that elementary teachers should find opportunities for elementary students to experience distance learning as an ongoing learning solution in order to incorporate innovative strategies that enhance their 21st century skills.

Introduction: The consumption of psychoactive substances (PAS) among schoolchildren suggests a complex phenomenon with multiple negative effects. From the perspective of social determinants and health promotion, the educational institution (EI) acts as a decisive agent for participatory actions. The present study aimed to identify individuals and institutional factors associated with the participation of students in an IE public of Cali (Colombia) toward the prevention of the consumption of PAS. Materials and methods: This is a case study with a qualitative and quantitative approach. The former involved a documentary analysis for the exploration of the response and the institutional factors of EI, which were selected as a critical case. Meanwhile, to identify the relevant individual factors, a quantitative component was developed through a survey of 156 students (Secondary­Middle School) of that EI. Results: Students identified pressure from friends or classmates as a relevant factor for PAS consumption, indicating that the spaces and prevention processes with the most significant contribution are communication with peers. The curricular work from the areas to strengthen decision-making is also recognized as an institutional factor. Conclusion: Within the healthy schools' strategy, the alliance between the education and health sectors is of crucial relevance for the promotion of the revitalization of spaces and participation processes aimed at preventing the consumption of PAS. The analysis of studies on the development of healthy schools strategy is thus required to generate elements of reflection directed toward the adjustment of the actions facilitating the empowerment of the students and those referring to youth participation to achieve the required continuity.

The Effect of Cardiopulmonary Resuscitation (CPR) Education on the CPR Knowledge, Attitudes, Self-Efficacy, and Confidence in Performing CPR among Elementary School Students in Korea.

Cardiopulmonary resuscitation (CPR) education for schoolchildren is emphasized, as bystander CPR is a vital key to increasing the survival rate of out-of-hospital cardiac arrest (OHCA) victims. This study was conducted to verify the effect of CPR education on knowledge, attitudes, self-efficacy, and confidence of Korean elementary school students in performing CPR. Data were collected through structured questionnaires before and after CPR education and analyzed using descriptive statistics, T-tests, and hierarchical regression. Significant improvements in CPR knowledge, attitudes, self-efficacy, and confidence in performing CPR were found after CPR education, with the greatest increase observed in confidence (p = 0.000). The influencing factors on confidence in performing CPR were school grade, attitude, and self-efficacy. Although a significant increase in schoolchildren's CPR knowledge after education was shown, knowledge did not affect confidence in performing CPR. Therefore, early CPR education which focuses on improving confidence in performing CPR is recommended. CPR education might raise attitude and self-efficacy leading to increased confidence in performing bystander CPR. In conclusion, early and regular CPR education for elementary school students is crucial and should be conducted repeatedly.

The Relative Strengths of Relationships Between Fine Motor Skills, Working Memory, Processing Speed and Fluid Intelligence in Early Elementary School Children.

The goal in the present paper was to examine the combined and relative impact of fine motor ability, auditory working memory, and processing speed on fluid intelligence in a sample of early elementary school students. Our participant sample was 145 children (Mage = 9.1 years, SD = 1.1; 80 boys, 65 girls). We used the Raven's Colored Progressive Matrices Test as a measure of fluid intelligence and five other measures to represent the three predictor variables: the Grooved Pegboard Test as a measure of fine motor skills, Digit Span Forwards and Digit Span Backwards tests as measures of working memory, and Rapid Automatized Naming and Letter-Digit Substitution tasks as measures of processing speed. Regression analyses indicated that only two of these measures had a statistically significant association with the fluid intelligence test scores, namely, scores on the Grooved Pegboard (fine motor skills) and Digit Span Backwards (working memory) tests, with these two measures explaining 35% of the variance in the fluid intelligence test scores. Thus, fine motor skills and working memory were correlated with fluid intelligence in early elementary-grade students. Until the directions of these relationships are better understood, we might assume that interventions aiming to increase young children's fluid intelligence, or at least their intelligence scores, might partly target working memory and fine motor skills.

An integrated model for predicting pupils' acceptance of artificially intelligent robots as teachers.

Artificially intelligent robots as teachers (AI teachers) have attracted extensive attention due to their potential to relieve the challenge of global teacher shortage and realize universal elementary education by 2030. Despite mass production of service robots and discussions about their educational applications, the study of full-fledged AI teachers and children's attitudes towards them is quite preliminary. Here, we report a new AI teacher and an integrated model to assess how pupils accept and use it. Participants included students from Chinese elementary schools via convenience sampling. Questionnaires (n = 665), descriptive statistics and structural equation modeling based on software SPSS Statistics 23.0 and Amos 26.0 were carried out in data collection and analysis. This study first developed an AI teacher by coding a lesson design, course contents and Power Point with script language. Based on the popular Technology Acceptance Model and Task-Technology Fit Theory, this study identified key determinants of the acceptance, including robot use anxiety (RUA), perceived usefulness (PU), perceived ease of use (PEOU) and robot instructional task difficulty (RITD). Moreover, this study found that pupils' attitudes towards the AI teacher, which could be predicted by PU, PEOU and RITD, were generally positive. It is also found that the relationship between RITD and acceptance was mediated by RUA, PEOU and PU. This study holds significance for stakeholders to develop independent AI teachers for students.

The Amount of Light to Vigorous Physical Activity (Met's-Hours/Day) in Children with and without Down Syndrome Attending Elementary School in Japan.

Children with Down syndrome (DS) have physical characteristics such as hypotonus of the musculature. Therefore, their attainment rate of physical activity guidelines is low, and guidelines alone may not be sufficient in assessing the amount of physical activity in children with DS. Compared with normal children (NC) of the same grade, light physical activity (LPA) must be considered while assessing physical activity of children with DS, owing to muscle hypotonia. This study included 69 children with DS and 68 NC in grades 4−6 attending elementary school in Japan. The measurements for physical characteristics included age, height, weight, and body mass index. Physical activity was measured using a triaxial accelerometer, which indicated physical activity volume. Children with DS had less moderate-to-vigorous physical activity duration (DS: 53.1 min/day, NC: 65.0 min/day; p < 0.001) but significantly longer LPA duration (DS: 376.4 min/day, NC: 287.7 min/day; p < 0.001) than NC. Conversely, the amount of light to vigorous physical activity (Met's-hours/day) was greater in children with DS (DS: 16.0 Met's-hours/day, NC: 14.4 Met's-hours/day; p = 0.037). In children with DS with muscular hypotonia, vigorous physical activity is challenging, but LPA is feasible. Developing and validating educational programs that promote physical activity with intensity level depending on individual's physical characteristic are warranted.

Can Regulatory Fit Improve Elementary School Students' Performance? Effects of Different Types of Regulatory Fit.

Previous studies have demonstrated the effect of regulatory fit on Japanese elementary school students (aged 9-12 years). The hypotheses were that promotion focused students tend to show good performance related to speed when they use an eager manner; on the other hand, prevention focused students tend to show good performance related to accuracy when they use a vigilant manner. In Study 1, the class teacher assessed their student's regulatory focus and then manipulated the students' manner of solving a calculation task by asking the students to engage speedily so that they solve many tasks in eager manner condition, or accurately so that they can avoid making errors in the vigilant manner condition. The results indicated that students with a promotion focus tended to solve more tasks in the eager manner condition. In addition, the same result was replicated in Study 2. These combined results suggest that regulatory fit is experienced not only by adults but also by young children. Moreover, the influence of regulatory fit depended on the type of regulatory fit. It is suggested that regulatory fit theory could be applied to educational settings to efficiently enhance the performance of students.

The Effect of Risk and Protective Factors on Primary School Students' COVID-19 Anxiety: Back to School After the Pandemic.

This study aimed to analyze the risk and protective factors affecting the COVID-19 anxiety of primary school students after the reopening. It was investigated how primary school students' parents' vaccination, and COVID-19 cases seen at school, knowledge and awareness directly or indirectly explained their individual and social COVID-19 anxiety. The data were obtained from 227 primary school students living in different regions of Turkey. Pandemic Awareness Scale, Pandemic Anxiety Scale, Pandemic Information Test and Information Form were used to obtain the data. The data were analyzed by path analysis. According to the results, the case seen at school, knowledge and awareness of COVID-19 directly and significantly predicted primary school students' individual and social COVID-19 anxiety. Vaccination of parents, on the other hand, directly significantly predicted social COVID-19 anxiety of primary school students, but did not significantly predict individual COVID-19 anxiety. In addition, in this effect, awareness of COVID-19 mediates the knowledge of COVID-19, and cases seen at school mediate the vaccination of parents. The obtained model showed a good fit. According to the results, primary school students' knowledge and awareness about COVID-19 and parents' vaccination reduced their anxieties, and COVID-19 cases seen at school increased their anxiety.

Comparison of the Cognitive Disengagement and Hypoactivity Components of Sluggish Cognitive Tempo in Autism, ADHD, and Population-Based Samples of Children.

An international Sluggish Cognitive Tempo (SCT) Work Group proposed a new term for SCT, "cognitive disengagement syndrome," that more accurately describes the syndrome than does SCT. According to the Work Group, symptoms of SCT represent a cognitive dimension (cognitive disengagement) and a motor dimension (hypoactivity). Our study determined (1) if distinct factors representing cognitive disengagement and hypoactivity emerged when SCT items were factor analyzed and (2) the degree of differences in cognitive disengagement and hypoactivity within diagnostic groups. Mothers rated 1,177 children with autism, 725 with ADHD-Combined, and 307 with ADHD-Inattentive (4-17 years) and 665 elementary school children (6-12 years) on the Pediatric Behavior Scale (PBS). SCT prevalence rates were autism 32%, ADHD-Inattentive 27%, ADHD-Combined 18%, and elementary school students 7%. Factor analysis of the SCT items yielded two factors reflecting cognitive disengagement (in a fog/confused and stares/preoccupied/in own world) and hypoactivity (sluggish/slow moving/low energy, drowsy/sleepy/not alert, and tires easily) in all diagnostic groups. Cognitive disengagement prevalence rates and scores were significantly higher than hypoactivity in the autism and ADHD-C groups and in the autism and ADHD-C subgroups of children with SCT (but not in the ADHD-I and elementary school total groups and SCT subgroups). Our findings factor analyzing five SCT items support two SCT subfactors: cognitive disengagement and hypoactivity.

Effectiveness of Education Using Comic Media on Knowledge About Covid-19 Among Elementary School Students

@#Introduction: Children typically have a diminished capacity to comprehend the COVID-19 epidemic. To convey information about COVID-19 to elementary school students (ESS), it takes educational comic media that children like because it is “fun,” “ informative, “ and well-understood. However, the effectiveness of this intervention has yet to be thoroughly investigated. This study aimed to measure the knowledge of ESS after studying COVID-19 with comics. Methods: A pre-post quasi-experimental design with a control group was used in this study. There were 66 ESS recruited on purpose. Intervention (n = 33) and control (n = 33) groups were formed. The intervention group received COVID-19 education using comic book media. Who Will Win the Fight Between Kids, Vaayu, and Corona?, a COVID-19 Awareness Comic, was translated into Indonesian. The education was given twice every two weeks, while the standard school intervention was given to the control group. To collect data, researchers designed a questionnaire based on a literature study. The questionnaire was valid and reliable, with a Cronbach alpha of 0.71, and the results were analysed using the independent sample t-test. Results: There was a substantial difference in Knowledge towards COVID-19 ratings between the control and intervention groups (p = 0.001). The mean Knowledge towards COVID-19 score of the intervention group was higher than that of the control group (M=4.33 vs M=1.63). Knowledge about COVID-19 differed significantly between the intervention and control groups (p = 0.001). Conclusion: Comic books are effective in increasing knowledge about COVID-19 in ESS.

Survey on iodine deficiency disorders awareness, education status and willingness of pupils in Guizhou Province / 中华地方病学杂志

Objective:To learn about the awareness, education status and willingness of iodine deficiency disorders (IDD) among elementary school students in Guizhou Province, and to provide a scientific basis for exploring intervention strategies for health education of iodine deficiency in the future.Methods:From June 2021 to May 2022, each IDD monitoring county was selected from the east, south, west, north and middle directions of Guizhou Province, and one elementary school was selected from each county. All students in two classes of Grade 5 and Grade 6 were selected in whole groups to conduct on-site questionnaire surveys in the form of anonymous examinations. The survey mainly included general demographic information and IDD awareness, education status and willingness, and binary logistic regression was used to analyze the relevant influencing factors.Results:A total of 1 259 elementary school students in Guizhou Province were investigated, the rates of awareness of IDD, acceptance of IDD publicity and education, and willingness to accept IDD publicity and education among elementary school students were 37.7% (1 900/5 036), 25.1% (316/1 259) and 69.6% (876/1 259), respectively. By binary logistic regression analysis, gender, residence, grade and father's education level were the influencing factors of pupils' awareness of iodine deficiency ( P < 0.05); residence, age and father's education level were the influential factors of elementary school students receiving iodine deficiency education ( P < 0.05); gender, residence, ethnicity and whether the child was the only child or not were the influential factors of elementary school students' willingness to accept IDD education ( P < 0.05). Conclusions:The elementary school students in Guizhou Province have insufficient knowledge about IDD. The publicity and education for iodine deficiency prevention is limited, and the students' willingness to learn is not high. The publicity, education and intervention for iodine deficiency prevention among elementary school students should be comprehensively strengthened.

The impact of working memory capacity on collaborative learning in elementary school students.

Working memory capacity may be a critical factor that influences the effectiveness of collaborative learning; however, no studies have directly explored this effect. Using worked examples as learning tasks, Experiment 1 used a 2 (working memory capacity) × 2 (learning format) factorial design to examine the effects of collaborative learning versus individual learning of 4th-grade Chinese elementary school students with different working memory capacities. High-capacity learners displayed less working memory resource depletion and better transfer performance during collaborative learning than individual learning. In contrast, no differences were found among the low-capacity learners. Collaborative learning benefited high-capacity learners but not low-capacity learners, per our observations. To further optimize collaborative learning for low-capacity learners and expand the findings to heterogeneous collaborative learning, Experiment 2 adopted a 2 (member capacity) × 2 (group capacity) factorial design to explore the effects of member and group working memory capacity on collaborative learning in heterogeneous groups. High-capacity members displayed less working memory resource depletion and better far transfer performance in high-capacity groups compared to low-capacity groups. Simultaneously, all members had better near transfer performance in high-capacity groups compared to low-capacity groups. Both member and group working memory capacities influenced the effect of heterogeneous collaborative learning. However, low-capacity members only partially benefited from collaborative learning in high-capacity heterogeneous groups.
