Recognition of interference and diffraction patterns is a difficult task for both high-school and university students. Many students fail to observe important features of particular patterns and identify the differences among similar patterns. In this study, we investigated if performing students' investigative experiments can help high-school…

When our school implemented AP Physics 1, I wanted to include a project that would extend over time, use more advanced data analysis, and teach students about handling experimental error. Using a donated 5-inch Newtonian telescope and an entry-level digital camera, the students gathered data from digital images of the four Galilean moons, Io,…

The course design "Training OC" for training the application of basic concepts consists of four topics: formula language, structure-property relations, reaction mechanisms, and complex tasks that the students should solve with the conceptual knowledge they acquired in the first three topics. A main goal of the course was to enable the…

Over 40 years of research, concept maps have shown that they are beneficial for learning. However, much of this research has been conducted in laboratory settings. Although there are a few studies conducted in the classroom, there is little understanding of the instructional efficacy of using different types of concept maps. In a between-subjects…

Cognitive diagnostic models can uncover students' mastery of multiple fine-grained skill attributes or problem-solving processes. A number of studies have applied cognitive diagnostic models to detect students' knowledge mastery in mathematics and language testing. However, few studies focus on cognitive diagnostic assessment in K-12 science…

The instructional decisions made by classroom teachers impact the learning acquired by students. The Common Core Mathematics Standards and the history of mathematics education in the United States create a background for how geometry standards are taught in one Midwest middle school. A study of the pacing guides, lesson plans, and naturalistic…

Science teachers' beliefs about teaching and learning are a vital component of teachers' professional competence and are often assumed to impact classroom practice. To date, these beliefs have been predominantly investigated regarding teaching and learning in general or for a particular science subject (e.g., physics). It remains to be determined…

Coordination class theory has proven to be a useful theoretical framework for describing processes of conceptual change in certain physical and mathematical concepts. Its development throughout different studies has allowed us to understand numerous mechanisms of conceptual learning by individual subjects. There have been attempts to implement…

This study describes the design and implementation of a science outreach program (elementary; 2nd-5th) and its associated student outcomes. Key features of the program include: (a) phenomenon-based, NGSS-aligned curriculum designed by science education experts and influenced by educational, sociocultural, and cognitive science theories, (b) active…

The Fluid Earth (FE) is an interactive data visualization initially developed for learning about Earth's atmosphere in informal educational settings. In this study, we tested FE in middle school classes to assess student engagement in a formal educational setting. Using a quasi-experimental design, students were assigned to interact with the data…

While Science, Technology, Engineering, and Mathematics (STEM) education is essential in the high school curriculum, it often carries a reputation of being formidable and overwhelming. The resulting unease students often face inhibits their ability to learn effectively; thus it can be beneficial to integrate a more familiar approach to teach them…

Assistive technologies are frequently used to help disabled students to access core and expanded core curricula and to improve their functional, communication and literacy skills. Non-optical low vision devices and optical and tactile graphics technologies are some of the assistive technologies used by visually impaired students in today's…

Context-Based Learning (CBL) and learning through developing and using models are two important teaching approaches for chemistry conceptual understanding. We aimed to examine the influence of a CBL approach on students' understanding of Multiple Models of Knowledge Representations ("MMKRs") and "multiple molecular…

There is growing interest in implementing reform-based lab courses in undergraduate physics that are student driven rather than instructor driven. In these courses, students develop and carry out experiments while simultaneously reasoning about their hypotheses, data collection procedures, collected evidence, and the relevant physics content.…

Science education motivates students to be problem solvers who utilize scientific knowledge for the social problems that they encounter in their lives. However, for better solutions for the problem, just knowledge of scientific concepts would not be enough because students need to approach problems aesthetically also. Understanding social,…
