Predicting adaptive expertise with rational number arithmetic.

BACKGROUND: Adaptive expertise is a highly valued outcome of mathematics curricula. One aspect of adaptive expertise with rational numbers is adaptive rational number knowledge, which refers to the ability to integrate knowledge of numerical characteristics and relations in solving novel tasks. Even among students with strong conceptual and procedural knowledge of rational numbers, there are substantial individual differences in adaptive rational number knowledge. AIMS: We aimed to examine how a wide range of domain-general and mathematically specific skills and knowledge predicted different aspects of rational number knowledge, including procedural, conceptual, and adaptive rational number knowledge. SAMPLE: 173 6th and 7th grade students from a school in the southeastern US (51% female) participated in the study. METHODS: At three time points across 1.5 years, we measured students' domain-general and domain-specific skills and knowledge. We used multiple hierarchal regression analysis to examine how these predictors related to rational number knowledge at the third time point. RESULT: Prior knowledge of rational numbers, general mathematical calculation knowledge, and spontaneous focusing on multiplicative relations (SFOR) tendency uniquely predicted adaptive rational number knowledge, after taking into account domain-general and mathematically specific skills and knowledge. Although conceptual knowledge of rational numbers and general mathematical achievement also predicted later conceptual and procedural knowledge of rational numbers, SFOR tendency did not. CONCLUSION: Results suggest expanding investigations of mathematical development to also explore different features of adaptive expertise as well as spontaneous mathematical focusing tendencies.

How does technology challenge teacher education?

The paper presents an overview of challenges and demands related to teachers' digital skills and technology integration into educational content and processes. The paper raises a debate how technologies have created new skills gaps in pre-service and in-service teacher training and how that affected traditional forms of teacher education. Accordingly, it is discussed what interventions might be applicable to different contexts to address these challenges. It is argued that technologies should be viewed both as the field where new competences should be developed and at the same time as the method used in developing learning environments for teacher students.

Learning History with Location-Based Applications: An Architecture for Points of Interest in Multiple Layers.

Location-based applications (LBAs) capture the user's physical location via satellite navigation sensors and integrate it as part of the digital application. Because of this connection, the real-world environment needs to be accounted for in LBA design. In this work, we focused on creating a database of geographically distributed points of interest (PoIs) that is optimal for learning local history. First, we conducted a requirements elicitation study at three outdoor archaeological sites and identified issues in existing solutions. Second, we designed a multi-layered prototype solution. Third, we evaluated the solution with nine experts who had prior experience with LBAs or similar systems. We incorporated their feedback to our design to iteratively improve it. As a whole, our work contributes to the LBA design literature by proposing a solution that is optimized for the learning of local history.

Conceptual changes for and during working life.

Rapid and radical changes in science, technology and society may result in new scientific concepts and new workplace practices, which require fundamental restructuring of prior knowledge. Over the years a noteworthy body of research has documented the processes of conceptual change, the learning mechanisms involved, and the instructional methods and strategies that can promote conceptual changes. This research, however, focused young learners in school settings. Conceptual changes in working life go beyond traditional conceptual change consisting of processes and mechanisms that involve the interaction between expertise development and workplace learning processes.This Special Issue investigates whether and how conceptual change research can be extended from learning in schools to learning in professional life.

Affect in Peer Group Learning During Virtual Science Inquiry: Insights From Self-Reports and Video Observations.

The purpose of this study was to explore affect in small groups learning together face-to-face in a virtual learning environment. The specific aims of the study were to establish how affect within groups (valence, intensity) related to the quality of group outcome (high, average, low), and to capture individual differences within the groups by using a multimethod approach. Participants were six groups of three high school students (N = 18) who achieved distinct outcome levels. Students' self-reports of their affect and observed affect (researcher-coded selected segments from videos) were used to examine affect during three phases of interdisciplinary science inquiry, namely, planning the experiment, experimenting in the virtual laboratory, and concluding and preparing a joint group presentation. The overall results showed that positive affect was prevalent in both self-reports and researcher-coded observations across all phases. However, while self-reports displayed a strong dominance of positive affect, there was more variation in observed affect. Furthermore, the intensity of affect was higher in self-reports than in observations, for both positive and negative affect. Nonetheless, no effect of affect on group outcome was found. Finally, while within-group consistency in affect was evident in the extreme groups (high, low performance), it was more ambivalent in the groups that achieved an average performance. The results are discussed in light of the literature, and directions for future research on affect in collaborative learning are proposed.

Histological knowledge as a predictor of medical students' performance in diagnostic pathology.

Over the years, the role and extent of the basic sciences in medical curricula have been challenged by research on clinical expertise, clinical teachers, and medical students, as well as by the development and diversification of the medical curricula themselves. The aim of this study was to examine how prior knowledge of basic histology and histopathology among students predicts early learning of diagnostic pathology. Participants (N=118, representing 91% of the full student cohort) were medical students at the University of Turku, Finland. Data were collected during two preclinical courses that students attended in their first and second years of medical school. The measurements included tests on biomedical and clinical knowledge and a performance test in diagnostic pathology. Second-year performance on the diagnostic pathology examinations was predicted by the students' prior knowledge of histology, but not by the students' prior knowledge of histopathology. Although earlier research has demonstrated similar results in studies with shorter longitudinal designs, the present study demonstrates that the effect remains even if there is a considerably long time delay (a year) between the measurements, thus confirming the long-term value of basic science studies in the preclinical phase.

Spontaneous focusing on numerosity as a domain-specific predictor of arithmetical skills.

The aim of this 2 year longitudinal study was to explore whether children's individual differences in spontaneous focusing on numerosity (SFON) in kindergarten predict arithmetical and reading skills 2 years later in school. Moreover, we investigated whether the positive relationship between SFON and mathematical skills is explained by children's individual differences in spontaneous focusing on a non-numerical aspect. The participants were 139 Finnish-speaking children. The results show that SFON tendency in kindergarten is a significant domain-specific predictor of arithmetical skills, but not reading skills, assessed at the end of Grade 2. In addition, the relationship between SFON and number sequence skills in kindergarten is not explained by children's individual differences in their focusing on a non-numerical aspect that is, spatial locations.

Do prior knowledge, personality and visual perceptual ability predict student performance in microscopic pathology?

OBJECTIVES There has been long-standing controversy regarding aptitude testing and selection for medical education. Visual perception is considered particularly important for detecting signs of disease as part of diagnostic procedures in, for example, microscopic pathology, radiology and dermatology and as a component of perceptual motor skills in medical procedures such as surgery. In 1968 the Perceptual Ability Test (PAT) was introduced in dental education. The aim of the present pilot study was to explore possible predictors of performance in diagnostic classification based on microscopic observation in the context of an undergraduate pathology course. METHODS A pre- and post-test of diagnostic classification performance, test of visual perceptual skill (Test of Visual Perceptual Skills, 3rd edition [TVPS-3]) and a self-report instrument of personality (Big Five Personality Inventory) were administered. In addition, data on academic performance (performance in histology and cell biology, a compulsory course taken the previous year, in addition to performance on the microscopy examination and final examination) were collected. RESULTS The results indicated that one personality factor (Conscientiousness) and one element of visual perceptual ability (spatial relationship awareness) predicted performance on the pre-test. The only factor to predict performance on the post-test was performance on the pre-test. Similarly, the microscopy examination score was predicted by the pre-test score, in addition to the histology and cell biology grade. The course examination score was predicted by two personality factors (Conscientiousness and lack of Openness) and the histology and cell biology grade. CONCLUSIONS Visual spatial ability may be related to performance in the initial phase of training in microscopic pathology. However, from a practical point of view, medical students are able to learn basic microscopic pathology using worked-out examples, independently of measures of personality or visual perceptual ability. This finding should reassure students about their abilities to improve with training independently of their scores on tests on basic abilities and personality.
