This study seeks to determine whether giving an explicit incentive to students in an upper-division first-semester electromagnetism course (EM1), in the form of partial credit for reworking unit exam problems, will improve their problem-solving skills as measured by performance on identical problems on the final exam. Three problems--a primarily…

In this study of 431 Grade 9 and 10 students, we investigated gender and frequency of practical work as determinants of science students' perceptions of their learning environment and attitudes. We assessed classroom environment with the Science Laboratory Environment Inventory (SLEI) and attitudes with the Students' Adaptive Learning Engagement…

A Cartesian conception of material space views each part as external to every other part: "partes extra partes." Because two material things cannot occupy the same space, each of it exists in itself, separated by a boundary from everything else, including other things. This ontology is the origin of thinking the world in terms of…

Two misconceptions about the mechanism of image formation in the human eye are common among students and even in textbooks and other teaching materials. The first attributes all refraction to the eye lens; the second treats the eye as a pinhole camera. To reduce these persistent conceptions of students, a series of simple experiments is presented…

This study examined the effects of concept maps on Senior School students' achievement in ecology in Ogbomoso, Nigeria. Quasi-experimental design was employed. The population for the study was all SSII Biology students in Ogbomoso South. Four intact classes of 267 students (115 males and 152 females) were sampled. The instrument was Biology…

Effective science education draws on many different ways of teaching science. The literature on science education documents some potential benefits of argumentation instruction as a powerful tool for learning science and maintaining wonder and curiosity in the classroom. Unlike expository teaching, which relies on a teacher-driven pedagogy in…

This study aims to investigate the situation of science teachers regarding out-of-school learning activities and to investigate how their participation in out-of-school learning activities as an observer within the scope of science courses creates a change in the situation of teachers. A case study was used in this study. Twenty-one science…

This study aims to determine the effectiveness of the author's teaching technology in developing schoolchildren's research skills, the challenges an elementary school faces, and how the entire process of developing research skills works. Quantitative and qualitative research techniques were used. Participants were from No.15, No.1, No.46, and…

When learning about the particulate nature of matter (PNM), students tend to attribute the same properties to both particles and to the substances they compose. It has been argued that this might be explained by them categorizing the wrong ontological category. To explain the relationships between submicroscopic and macroscopic levels of matter,…

Estimating reliability for single-item motivational measures presents challenges, particularly when constructs are anticipated to vary across time (e.g., effort, self-efficacy, emotions). We explored an innovative approach for estimating reliability of single-item motivational measures by defining reliability as consistency of interpreting the…

This study aimed to explore Cooperative Learning theories and practice by examining the relationships among three aspects: Experience, Practice and Perceptions. The data were from interview records from eight science teachers. As a student-centered active pedagogical trend, cooperative learning has become part of one of the most effective and…

This dissertation focused on the outcome of elementary science teachers' learning in theories and practices of epistemic tools in professional workshops over the course of two years, starting in the summer of 2019. Study one focuses on teachers' understanding of language as an epistemic tool. The data were teachers' written responses to a…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] In recent years, physics instructional labs have been under considerable research and development. However, there seems to be no shared understanding of how the assessment of instructional labs should be arranged to best serve students'…

Evolution is a key feature of undergraduate biology education: the American Association for the Advancement of Science (AAAS) has identified evolution as one of the five core concepts of biology, and it is relevant to a wide array of biology-related careers. If biology instructors want students to use evolution to address scientific challenges…

In this study, I documented, analyzed, and compared the thought processes of six high school science teachers during twenty minutes of planning for NGSS-aligned instruction. Teachers' thoughts were captured using a virtual revisit think-aloud protocol and their thoughts were analyzed and compared using a novel tool called a thinking web. A…
