POTENTIAL OF THE GRAPHIC NOVEL "BLUE PILLS" TO DEMYSTIFY STIGMAS ABOUT HIV THROUGH CURRICULAR CONTENT / POTENCIAL DE LA NOVELA GRÁFICA "PÍLDORAS AZULES" EN DESMITIFICAR ESTIGMAS SOBRE EL VIH ATRAVÉ DE CONTENIDOS CURRICULARES / POTENCIAL DO ROMANCE GRÁFICO "PÍLULAS AZUIS" EM DESMISTIFICAR ESTIGMAS SOBRE HIV ATRAVÉS DOS CONTEÚDOS CURRICULARES

Despite advances in public policy and health care, it is estimated that more than 1 million people in Brazil live with HIV. Health education is an important prophylactic measure that could help disseminate information to reduce the increase in cases. Among the various strategies used in educational processes, visual media are strong allies due to their significant communication potential. The objective of this study was to analyze the graphic novel "Blue Pills" to identify its potential for addressing HIV in science and biology education. "Blue Pills" is an autobiographical graphic novel by Frederik Peeters that depicts his challenges and anxieties upon discovering that his girlfriend, Cati, and her son are HIV positive. We conducted a content analysis of the work, examining both visual and textual elements to evaluate its potential use in teaching. Our analysis identified 67 excerpts related to the research topic, which we categorized into five themes: "Prejudices and Stigmas," "Care and Treatment," "Transmission and Reproduction of the Virus," "Emotional and Psychological Impacts," and "Social View of Science." Peeters effectively presents HIV in an empathetic and accessible manner, contextualizing complex and often stigmatized issues for readers. Consequently, we believe the material has potential for educational use, despite existing restrictions in the Brazilian National Common Curricular Base (BNCC). Additionally, it contributes to the social debate on issues pertinent to the daily lives of HIV-positive individuals, helping to demystify stigmas entrenched in the collective imagination.

A pesar de los avances en políticas públicas y atención sanitaria, se estima que en Brasil más de 1 millón de personas viven con VIH. La educación sanitaria es un proceso de profilaxis importante que puede contribuir a la difusión de información para mitigar el aumento de casos. Entre las diferentes estrategias utilizadas en los procesos educativos, los productos visuales son fuertes aliados debido a su gran potencial comunicativo. El objetivo de este trabajo fue analizar la novela gráfica "Píldoras Azules" con el fin de identificar su potencial para abordar el VIH en la educación en ciencias y biología. "Píldoras Azules" es una novela gráfica autobiográfica de Frederik Peeters que presenta sus desafíos y angustias al descubrir que su novia Cati y su hijo son VIH positivos. Realizamos un análisis de contenido de la obra, observando los elementos visuales y textuales que pueden posibilitar su uso en la docencia. Tras el análisis, identificamos 67 extractos con enfoques relacionados con el tema objeto de la investigación. Los extractos están organizados en 5 categorías: "Prejuicios y estigmas", "Cuidado y tratamiento", "Transmisión y reproducción del virus", "Impactos emocionales y psicológicos" y "Visión social de la ciencia". En su obra, Peeters logra abordar el VIH de una manera empática y fácil de entender, contextualizando temas complejos y reprimidos en la sociedad para el lector. Por lo tanto, entendemos que el material presenta posibilidades de uso en la enseñanza, a pesar de las restricciones existentes en el BNCC, además de aportar al debate social cuestiones pertinentes a la vida cotidiana de las personas VIH positivas, desmitificando estigmas presentes en el imaginario colectivo.

Assim, identificamos que o material apresenta potencial de utilização no ensino, apesar das restrições existentes na BNCC, assim como trazer para o debate questões sociais pertinentes ao cotidiano de pessoas soropositivas, desmistificando estigmas presentes no imaginário coletivo.

Metacognitive scaffolding for preservice teachers' self-regulated design of higher order thinking tasks.

This study compared two professional training courses targeting self-regulated learning (SRL) amongst preservice secondary science teachers in the context of didactic content knowledge for teaching higher-order thinking (HOT-PCK), either with metacognitive scaffolding (Meta group) or without (Control group). Measures included trainees' comprehension and design of HOT-PCK learning tasks, online SRL reflections about learning-teaching events, and self-reported SRL aptitude. Results indicated skill improvement in both groups, but the metacognitive support provided by the IMPROVE self-questioning technique better enhanced the preservice teachers' (PSTs) development of HOT-PCK, both as students (comprehension skills) and as future teachers (design skills), additionally as their ability to reflect on and control their studying. Findings also revealed significant correlations between SRL assessments (self-reports, event-based reflections) and between SRL and HOT-PCK indices. Consequences for teacher education combining SRL and HOT-PCK contexts are discussed.

Food safety knowledge among 7th-grade middle school students: A report of a Brazilian municipal school using workshop-based educational strategies.

Practical methodologies that include food safety and hygiene education in pedagogical activities are strategies to prevent foodborne diseases (FBDs). Thus, the aim of this study was to investigate the knowledge of 7th-grade middle school students regarding food microbiology and food safety, and to apply workshop-based educational strategies that focus on scientific literacy. The students (144) were initially evaluated using a Likert-scale questionnaire (pre-intervention, Q0) with ten objective questions on microbiology and food safety. Once the questionnaire was evaluated, interventions were conducted through five science workshops of 50 min, over a period of 5 months. The workshops included educational games, laboratory practices, videos, and lectures that addressed microorganisms that are known to cause the most common FBDs in Brazil. After each workshop, students were asked to express their opinions and understanding of the content through semi-structured interviews. Six months after the end of the practical interventions, the students completed a second identical Likert-scale questionnaire (post-intervention, Q1), and the answers to both questionnaires (Q0 and Q1) were analyzed by calculating the middle rank. The middle rank of Q1 (mean = 0.65 ± 0.13) was 21% greater than the middle rank of Q0 (mean = 0.44 ± 0.16), and statistical significance was observed (p = .0135). This demonstrates that new information acquired during the workshops positively influenced learning. We believe that when practical approaches to food safety are included in school education as a priority, the prevalence of FBD will decrease.

Preschool teachers' pedagogical content knowledge predicts willingness to scaffold early science learning.

BACKGROUND: The importance of diagnostic and scaffolding activities for early science learning has been shown consistently. However, preschool teachers scarcely engage in them. We developed an instrument to assess preschool teachers' willingness to engage in diagnostic and scaffolding activities in science learning situations and examined its relation with teachers' knowledge, beliefs and practice. AIMS: We validate an instrument to assess willingness to engage in scaffolding and diagnostic activities and study the interplay between willingness, learning beliefs, content knowledge (CK) and pedagogical content knowledge (PCK) in the context of science learning, particularly block play. SAMPLE(S): A total of N = 151 preschool teachers from 41 kindergartens in Germany participated in our study. METHODS: Preschool teachers completed a questionnaire, which took approximately 1 hour of time. We drew a subsample of N = 73 teachers and observed their practice during a 30 min block play episode. RESULTS: With our instrument, we were able to distinguish between preschool teachers' willingness to diagnose and to scaffold. Preschool teachers' co-constructivist beliefs and PCK predicted willingness to engage in diagnosing, PCK also predicted willingness to engage in scaffolding. Associations between learning beliefs and practice were inconsistent. CONCLUSIONS: Our study highlights aspects of the association between preschool teachers' PCK and their willingness to engage in diagnosing and scaffolding. However, we found inconsistencies between preschool teachers' beliefs and practice, which call for further clarification.

The Impact of Collaboration Between Science and Religious Education Teachers on Their Understanding and Views of Argumentation.

Teachers' understanding and teaching of argumentation is gaining more attention in science education research. However, little is known about how science teachers engage in argumentation with teachers of different subject taking an interdisciplinary perspective that may inspire new pedagogical ideas or strategies. In particular, the positioning of argumentation at the juncture of science and religion is rare. This paper reports an empirical study involving science and religious education (RE) teachers who collaborated on teaching argumentation in three secondary schools in England. Their interdisciplinary collaboration was sustained by a series of professional development sessions over 18 months. Analysis of the interview data unfolds how the teachers' collaboration impacted their understanding of argumentation and views of teaching their subject. Through working relationally in exploring and teaching argumentation, the science teachers reflected more notable changes than their RE counterparts. Science teachers came to appreciate student voice in the learning process and the role of argumentation in fostering students' scientific reasoning. The paper is a salient step to researching argumentation in a cross-curricular terrain, particularly in relation to RE. It also sheds light on how collaborating with teachers of another subject bolstered science teachers' professional development and broke subject barriers.

Impact of Cooperative Learning and Project-Based Learning through Emotional Intelligence: A Comparison of Methodologies for Implementing SDGs.

Education for sustainable development (ESD) is a holistic and transformative form of education that seeks action-oriented pedagogy using self-directed learning, participation, and collaboration, among other aspects, and is suitable for developing active methodologies. Since affective-emotional aspects can contribute in the teaching-learning process, this work studies, through a case study, the comparison of the influence of two active methodologies: Cooperative Learning (CL) and Project-Based Learning (PBL) in student emotions and learning processes, as well as their awareness of ESD. For that purpose, a survey was conducted at the fourth secondary level in the science laboratory, subjected to the innovation project e-WORLD, which developed the content of the 7 and 13 Sustainable Development Goals (SDGs) from the 2030 Agenda. Results of ANOVA and Tukey's tests carried out showed that both methodologies improved skills and knowledge related to climate change and energy, and triggered major positive emotions in students. Furthermore, CL allowed students to acquire more individual and group responsibility than communication skills developed with PBL. It is necessary to continue working on the involvement of students in these methodologies in order to improve their social skills and to reveal life changes towards more socio-sustainable ones.

The use of simulated crime scenes in teaching undergraduate forensic sciences: Implementing an active learning approach to forensics.

Incorporating a simulated crime scene into one's pedagogy in forensic science undergraduate courses allows students the opportunity to experience a realistic scenario while demonstrating their knowledge and enhancing their critical thinking skills. The purpose of this paper is to examine an active learning approach to using simulated crime scenes to provide an impactful learning experience for students. While potentially challenging for the instructor, constructing a crime scene scenario can provide students with hands-on practical experience while helping to dispel forensic science misconceptions. Through many years of creating crime scenes, best practices for using such high impact activities in forensic science courses are described in detail, including preparatory exercises that culminate in the final crime scene scenario, considerations in preparing and constructing a crime scene activity, and supervising and assessing students once the activity begins. Three major challenges to implementing active learning exercises such as simulated crime scenes in undergraduate forensic science programs include high workload for instructors, limited supplies, and lack of suitable facilities. Workload solutions include instructors and departments considering the cost and benefit of course releases to improve curriculum and student enrollment. Supplies and facilities solutions involve innovation in reuse and repurposing of supplies, and instructor flexibility in using classroom and outdoor spaces.

Three-Dimensional Models of Soil-Transmitted Helminth Eggs from Light Microscopy Images.

The World Health Organization indicates that more than 1.5 billion people are infected with geohelminths. Soil-transmitted helminths prevail mostly in tropical and subtropical regions, in areas with inadequate hygiene and sanitation conditions, and basic health education problems. Nematode eggs are structures of resistance and infection by fecal-oral transmission. When STH eggs are ingested, they can infect the potential host, causing abdominal pain, diarrhea, anemia, malnutrition, and physical-cognitive impacts in children. Taking advantage of the increasing employment of three-dimensional models of these structured based on light microscopy images to improve the research area and education could be an alternative to improve health education and spread scientific information on transmission and prevention. The objective of this work was to produce 3D printed models from bi-dimensional images of eggs based on their real morphological and morphometric characteristics. The virtual models were reconstructed from the acquisition and selection of images obtained using light microscopy. After selecting referential images, we constructed the models based on the vectorization of the egg structures. After vectorization, 3D modeling was performed and printed in PLA. 3D models have a high potential to contribute to the advanced morphological studies and teaching of parasitological sciences, enriching the teaching-learning process applicable in presential or remote teaching of basic education, undergraduate, and post-graduation classes.

Comparative Analysis of Teaching at Public Universities in Sinaloa during Confinement Due to COVID-19.

The COVID-19 pandemic has affected educational institutions around the world. One partial solution for students and teachers to continue the academic process involved the use of software and hardware technologies via the internet. The main objective of this research was to analyze the actions carried out by computer science teachers (and teachers who taught related degrees) in Sinaloa, Mexico, during the COVID-19 confinement period, to determine if the working conditions were different at all educational institutions. Based on quantitative, descriptive-explanatory, correlational, field, and cross-sectional approaches to data collection-a survey was designed and sent to teachers who taught classes in computer science and related careers. The results showed that although teachers felt prepared in designing and implementing virtual courses (90.73%), 68.5% believed that virtual classes were not enough for students (i.e., regarding replacing the training being offered). Likewise, teachers observed that only 27.8% of their students showed real commitment to online classes. In the hypothesis test, a chi-squared value of 3.84 was obtained, with a significance (p-value) of 0.137. There was a probability of error of 13.7%; this is high, considering that the level of significance must be 0.05 (5%) or less. It was concluded that teachers must be permanently trained in the use of new digital technologies; in addition, they must continuously produce academic material and make it available to the educational community. It is necessary for universities to design plans for the regulated use of applications and devices for academic purposes, update study plans and programs, and train teachers and students beyond conventional education.

Assessing the effect of case-based teaching compared with lecture-based teaching on students' knowledge and perceptions in a senior undergraduate dairy cattle management course.

Animal science students need to apply the knowledge acquired during their degree program to real-life scenarios in future careers. Little to no research exists evaluating the effects of case-based (CB; material presented as a case study) and lecture-based (LB; material presented as a lecture) teaching in animal science in higher education. The objectives of this study were to determine the effects of CB and LB teaching methods on student performance and to assess students' attitudes toward CB and LB teaching methods in a senior dairy cattle management course. A cross-over study design was conducted over two course modules (1 = "calf health" and 2 = "lameness") with a washout period of 2 wk. Students (n = 25) were randomly assigned to CB or to LB in module 1 and received the other method in module 2. Students completed a pre- and post-quiz in each module that consisted of 10 multiple-choice questions and 3 short-answer questions. Three separate linear mixed regression models were used to assess the effect of teaching method (CB or LB; predictor) on three different continuous outcomes for student performance: change (post-score - pre-score) in short-answer quiz scores, change in multiple-choice quiz scores, and the change in total quiz scores. Students completed an attitude assessment after each module that consisted of 8 Likert-scale statements and 2 free-response questions. Data were deidentified, and two researchers blinded to students' CB or LB status analyzed free responses to identify themes. A logistic regression, which controlled for module and included student as a repeated measure, was used to determine if the proportion of students who agreed (outcome: yes/no) with each Likert-scale statement was different between CB and LB. There was a tendency for CB teaching methods to improve change in multiple-choice quiz scores (P = 0.06). The change in total quiz scores and the change in short-answer quiz scores did not differ between CB and LB groups (P > 0.1). For the survey statements "I enjoyed the teaching method used in this module" and "I wish this teaching method was utilized in more of my classes," more students in LB agreed than in CB (P < 0.05). The themes preference, perceived benefits, and perceived drawbacks were mentioned in 80%, 44%, and 28% of CB comments, and in 84%, 40%, and 18% of LB comments, respectively, and suggest that students enjoy case studies but prefer to receive information via lecture first.

The use of system dynamics for energy and environmental education.

The use of system dynamics as a learning tool for developing sustainable energy strategies and environmental education has advanced in recent years with the availability of new modelling software and webtools. Among the existing models, we highlight the online 2050 Calculators, which aim at simulating scenarios for greenhouse gas emissions, energy planning, sustainable land use, and food consumption. The objective of this study is to assess the available calculators and their contribution to an interdisciplinary education via systems thinking. We carried out a review of the existing models worldwide and ran some of the tools with students from three different postgraduate programmes at master's level at Imperial College London (United Kingdom) and IFP School (France), whilst also assessing their individual views afterwards. The assessments were conducted once a year during three subsequent years: 2019, 2020, and 2021. The results are discussed under the epistemology of critical pedagogy, showing that the use of webtools, such as the 2050 Calculators, can significantly contribute to the students' environmental awareness and political engagement, providing important lessons about the use of system dynamics for policy and science education.

Examining teachers' self-regulation practice in secondary school science teaching: the case of South Gondar Zone, Ethiopia.

The problem of quality education is a burning worldwide issue nowadays. Teachers' teaching quality and effectiveness is one of the major contributing factors for quality education. Self-regulated teaching is becoming the new innovative strategy for quality teaching. Hence, the purpose of this study was to investigate the practice of self-regulated science teaching in the secondary schools of South Gondar Zone of Ethiopia. Nine (9) secondary schools were selected randomly. After selecting the schools, all science teachers, 322 (chemistry, biology and physics) in the selected schools were taken as participants using comprehensive sampling techniques.302/322 = 93.8% (of which 71 (23.5%) were females, 231 (76.5%) were males; 98 = 32.5% chemistry, 100 (33.1%) Biology and 104 (34.4%) Physics) teachers completed the questionnaire. One sample t-test, independent sample test, descriptive statistics and multiple regression analysis were used for data analysis. The findings indicated that there is a positive significant difference between the expected and observed mean of teachers' self-regulated science teaching and it is not by chance. Moreover, teachers are found implementing phase one or preparatory phase (forethought) phase (goal setting, performance goal orientation, mastery goal orientation and intrinsic interest) more than other phases. The study results also showed that there is a significant difference in the implementation of self-regulated science teaching between male and female teachers (females are found better than males). However, gender and teachers' experience together were not found a significant predictor of self-regulated science teaching. The study needs further evidence using observation and interview and the result would have a message for teacher educators to further investigate and adapt in their training manuals to improve teachers' teaching quality.

O uso de mapas conceituais e curtas metragens de temática química no estudo de temas da Sociologia / The use of conceptual maps and short films about chemical theme in the study of sociology themes

O objetivo deste estudo interdisciplinar foi usar curtas metragens produzidos por estudantes do ensino médio sobre temas da Química para o ensino de Sociologia. Neste sentido, foram produzidos mapas conceituais pelos estudantes, após a discussão dos curtas metragens, sob uma perspectiva sociológica. Nossos resultados mostram que os mapas conceituais podem atuar como instrumentos facilitadores para a aprendizagem, capazes de estimular a pesquisa e promover a autonomia dos estudantes durante o processo de construção do conhecimento.

Los datos fueron recolectados en base a test de concepciones y conocimientos, más encuesta de valoración. El análisis de los datos reveló que las estaciones de aprendizaje son una metodología de enseñanza efectiva en el aprendizaje de la célula, ya que permiten mejorar significativamente las concepciones previas de los estudiantes, los cuales valoran de manera positiva y significativa la metodología de la que fueron partícipes.

SUMMARY: The aim of this study was to determine the influence of the implementation and application of the learning stations teaching methodology on active learning of the physiology and morphology of the cell. We worked with 90 high school students, distributed in a control group and an experimental group, who received traditional classes and the application of the learning stations methodology, respectively. The data were collected based on a conception and knowledge test, plus an evaluation survey. The analysis of the data revealed that the learning stations are an effective teaching methodology in learning of the cell, since they allow to improve prior perceptions of the students, who significantly and positively value the methodology in which they participated.

Adaptación de la metodología didáctica a la virtualidad en los cursos de procesamiento técnico de la Escuela de Bibliotecología y Ciencias de la Información de la Universidad de Costa Rica / Adaptation of the didactic methodology to virtuality in the technical processing courses of the School of Library and Information Sciences of the University of Costa Rica

Resumen Este artículo tiene la finalidad de identificar la percepción estudiantil ante la adaptación de la metodología didáctica a la virtualidad en los cursos de procesamiento técnico BI-2001 Catalogación I y BI-3001 Indización, de la Escuela de Bibliotecología y Ciencias de la Información de la Universidad de Costa Rica, durante el I Ciclo lectivo del 2020. Para alcanzar dicho objetivo se realizó una investigación de tipo cuantitativa en la que se aplica un cuestionario en línea para analizar aspectos como el acceso que poseen a las clases virtuales y percepción respecto a las metodologías didácticas aplicadas. Se evidencia que contar con un adecuado acceso a internet es fundamental para continuar con el proceso educativo bajo la modalidad virtual, así como la importancia de adaptar los materiales didácticos y las evaluaciones que tradicionalmente se realizaban de manera presencial, considerando los factores que intervienen en la educación virtual.

Abstract This article identify the student perception of the adaptation of the didactic methodology to virtuality in the technical processing courses BI-2001 Cataloging I and BI-3001 Indexing, at the School of Library and Information Sciences of the University of Costa Rica, during the I school year of 2020. To achieve this objective a quantitative research was carried out in which an online questionnaire was applied to analyze aspects such as the access they have to virtual classes, perception regarding the applied didactic methodologies. It is observed that having an adequate internet access is essential to continue with the educational process under the virtual modality, as well as the importance of adapting the didactic materials and assessments that were traditionally carried out in person, considering the factors that intervene in the virtual education.

Understanding new molecular and cell biology findings based on progressive scientific practices and interconnected activities in undergraduate students.

Nowadays Molecular Cell Biology (MCB) must be taught as science is practiced. Even though there are several approaches based on scientific practices, a key aspect is to define the purpose of each of these teaching strategies and, most importantly, their implementation. Our goal was to train students to acquire, understand, and communicate new scientific knowledge in the field. The main feature of our new teaching methodology was progressive training in scientific practices associated with a back-and-forward interplay between activities and assessments. The methodology was implemented over 4 years, in students attending the MCB course of the undergraduate degree in Biological Sciences. In the first two modules, the students were prepared to comprehend MCB concepts and techniques and to experience activities based on scientific practices. In the third module, the students analyzed a primary paper in-depth. They were assessed by midterm exams based on a primary paper, written laboratory reports, and the oral presentation of a scientific paper. Our teaching proposal was evaluated through the students' academic performance and by their opinion on the teaching methodology. Most students were satisfied since they improved their acquisition of concepts, their interpretation and integration of scientific knowledge, and developed skills to communicate scientific knowledge in writing and orally. The novelty of transversal interconnections and progressive training in scientific practices provides students with skills in acquiring and understanding new scientific information, even beyond the MCB course.
