Applying a resources framework to analysis of the Force and Motion Conceptual Evaluation

We suggest one redefinition of common clusters of questions used to analyze student responses on the Force and Motion Conceptual Evaluation (FMCE). Our goal is to move beyond the expert/novice analysis of student learning based on pre-/post-testing and the correctness of responses (either on the overall test or on clusters of questions defined solely by content). We use a resources framework, taking special note of the contextual and representational dependence of questions with seemingly similar physics content. We analyze clusters in ways that allow the most common incorrect answers to give as much, or more, information as the correctness of responses in that cluster. Furthermore, we show that false positives can be found, especially on questions dealing with Newton's Third Law.Comment: 13 pages, 7 figures, submitted to Phys. Rev. ST Phys. Educ.

The older, the wiser? profiles of string instrument teachers with different experience according to their conceptions of teaching, learning, and evaluation

However, studies on conceptions and practices of teaching-learning show that these still largely focus on transmitting the musical and technical knowledge needed to produce the correct sound. Our main aim was to study the conceptions of teaching-learning held by 53 string teachers at elementary levels, and to test how they are affected by the variable teaching experience (in three groups: [a] less than 7 years; [b] 7-14 years; and [c] more than 14 years). We also wanted to determine whether these conceptions give rise to consistent profiles in three pedagogical dimensions: teaching, learning, and evaluation. We collected data by means of a multiple-choice questionnaire, and applied cluster analysis, correlations, analysis of variance (ANOVA), and post hoc tests. Agreeing with prior research, we found three distinct profiles in the answers to the questionnaire: direct, interpretative, and constructive. Teachers' beliefs were more constructive regarding teaching and evaluation than regarding learning, although younger teachers held more complex positions regarding teaching and learning music, in contrast to much research on teaching-expertise

Using an extended ICAP-based coding guide as a framework for the analysis of classroom observations

Available online 13 April 2023A coding guide based on the Interactive, Constructive, Active, Passive (ICAP) theory was developed and used to analyze the transcripts from filmed classroom observations. The analysis focused on the lesson tasks used by the 20 participating teachers to promote student cognitive engagement and the links between these tasks and student learning. The results showed that a) only 30% of the lesson tasks were assigned the Constructive and Interactive codes, and b) there were important teacher differences. About half of the teachers provided no or very few opportunities for Constructive or Interactive student cognitive engagement in their lessons.Stella Vosniadou, Michael J.

Using resource graphs to represent conceptual change

We introduce resource graphs, a representation of linked ideas used when reasoning about specific contexts in physics. Our model is consistent with previous descriptions of resources and coordination classes. It can represent mesoscopic scales that are neither knowledge-in-pieces or large-scale concepts. We use resource graphs to describe several forms of conceptual change: incremental, cascade, wholesale, and dual construction. For each, we give evidence from the physics education research literature to show examples of each form of conceptual change. Where possible, we compare our representation to models used by other researchers. Building on our representation, we introduce a new form of conceptual change, differentiation, and suggest several experimental studies that would help understand the differences between reform-based curricula.Comment: 27 pages, 14 figures, no tables.

Challenging the Science Curriculum Paradigm: TeachingPrimary Children Atomic-Molecular Theory

Solutions to global issues demand the involvement of scientists, yet concern exists about retention rates in science as students pass through school into University. Young children are curious about science, yet are considered incapable of grappling with abstract and microscopic concepts such as atoms, sub-atomic particles, molecules and DNA. School curricula for primary (elementary) aged children reflect this by their limitation to examining only what phenomena are without providing any explanatory frameworks for how or why they occur. This research challenges the assumption that atomic-molecular theory is too difficult for young children, examining new ways of introducing atomic theory to 9 year olds and seeks to verify their efficacy in producing genuine learning in the participants. Early results in three cases in different schools indicate these novel methods fostered further interest in science, allowed diverse children to engage and learn aspects of atomic theory, and satisfied the children’s desire for intellectual challenge. Learning exceeded expectations as demonstrated in the post-interview findings. Learning was also remarkably robust, as demonstrated in two schools eight weeks after the intervention, and in one school, one year after their first exposure to ideas about atoms, elements and molecules

‘Even though it might take me a while, in the end, I understand it’: a longitudinal case study of interactions between a conceptual change strategy and student motivation, interest and confidence

Although there have been many investigations of the social, motivational, and emotional aspects of conceptual change, there have been few studies investigating the intersection of these factors with cognitive aspects in the regular classroom. Using a conceptual change approach, this case study reports experiences of a student of low to average prior attainment who achieved high levels of conceptual gains in five science topics over a two-year period. Her experience in the cognitive, social and affective domains was probed through analysis of interviews, student artefacts, video recordings of classroom learning, pre/post-tests and questionnaire results. For this student, peripheral or incidental persuasion of belonging to a supportive small group initially led to greater engagement with the construction of understanding through production of multiple student-generated representations, resulting in improved self-confidence and high levels of conceptual change. Evidence of transfer from performance to mastery approach goals, adoption of positive activating emotions and increased interest in science were observed. This study highlights that adoption of a multidimensional conceptual change approach with judicious organisation of small groups to support construction of verbal, pictorial and written representations of understanding may bring about changes in motivational stance, self-confidence and emotions to maximise conceptual change
