Understanding of fractions is difficult for Indonesian students. This often leads to misinterpretation in solving fractional problems. In this study, a task aiming at identifying students' struggles in understanding the basic concept of part-whole relationships in fractions was developed and tested with six 4th-grade students. The task uses…

The authors outline some of the ways in which they teach student teachers to think about the challenges of abstract concepts in science. They ask the student teachers to think about abstract ideas in a non-science context first, and find they are enabled to discuss and engage (and then later apply) their thinking better. The authors think that…

The Tchokwe people lived on the African continent, in Mozambique and Angola. The sona belong to their cultural tradition. The sona are drawings made in the sand by older members of the tribe to tell stories, essential in the youngests' formation. In this article, we show a relationship between the sona and the greatest common divisor (GCD) of two…

Today's complex problems transcend borders and require a collective and adaptive learning response. Literature suggests that, because the traditional hierarchical or positional style of leadership cannot effectively address problems we face today, leadership should take a more collaborative and systemic form. Rost (1991) characterized this new…

This dissertation reports on three studies about students' conceptions and learning of the idea of instantaneous rate of change. The first study investigated 25 students' conceptions of the idea of instantaneous rate of change. The second study proposes a hypothetical learning trajectory, based on the literature and results from the first study,…

Economic literacy is critical for success in one's career and life. Such literacy has never been more relevant than today due to supply-chain issues causing product shortages, surging inflation, and rising interest rates. Discovery learning through active learning materials discussed in this article were employed with fifth and sixth-grade…

High-voltage plasma arcs from solid-state Tesla coils were used to produce characteristic atomic emissions of various metals. The colored arcs produced were highly visible and vibrant, making for a spectacularly engaging demonstration for groups of varying sizes. The demonstration used an inexpensive solid-state Tesla coil to generate low-current,…

This conceptual paper discusses two frameworks, developed independently by the lead author, that will provide the conceptual foundation for the identification and evaluation of mental computation strategies students demonstrate during an upcoming research project entitled Mental Computation in Year 5. These frameworks will be used by the lead…

This paper reports on concept images of 38 secondary school mathematics prospective teachers, regarding the evenness of numbers. Written assignments, individual interviews, and lesson transcripts uncover salient, erroneous concept images of even numbers as numbers that are two times "something" (i.e., "2i" is an even number),…

In this study we explore how incorporating an arts-based pedagogical approach, specifically, the use of film, art, and music, into a second-year sociological theory course enhances students' overall learning experiences. We report on data collected from a survey given to students enrolled in this course in 2020. Findings reveal that employing this…

This study investigated the effects of a place value intervention with third-grade students with learning disabilities. The intervention added content to a research-based intervention using the concrete-representational-abstract (CRA) sequence. The added content reflected current mathematics standards for third grade. Students' place value…

Design-based learning is considered a powerful way to help students apply and develop understanding of science concepts, but research has shown that the success of this approach is not a given. Examining students' understanding of science concepts in various design-based learning contexts has thus continued to be an important field of research. To…

Research shows that effective and high-quality instructional coaching that targets teacher-child interactions can improve the classroom quality, increase teacher job satisfaction, reduce attrition, and even improve young children's development, such as social emotional development, and literacy skills. Coaches likely develop and sharpen their…

Previous research has shown that students form fragmented understandings about variability even after instruction and that these primitive notions function as obstacles to a robust understanding of variability. To investigate the effect of disruptions to students' primitive notions of variability, we examined undergraduate students' reasoning…

A core challenge for team innovation is the successful translation of creative ideas into innovation through implementation. This study examines the tension between internal and external team resourcing behaviors that account for how teams translate their creative ideas into implemented innovation. Drawing on conservation of resource theory, we…
