Background: Previous studies have investigated effects of out-of-school STEM activities aimed at stimulating children's interest in science with positive results. However, research has not discussed the reasons why such activities are successful. Purpose: In this study, we address this gap by investigating which factors children themselves…

Conceptually understanding chemistry requires the ability to transition among representational levels to use an understanding of submicroscopic entities and properties to explain macroscopic phenomena. Past literature describes student struggles with these transitions but provides limited information about upper-level post-secondary chemistry…

Drawn from the cultural-historical theories of knowing and doing science, this article uses the concept of professional vision to explore what scientists and experienced teachers see and articulate as important aspects of climate science practices. The study takes an abductive reasoning approach to analyze scientists' videotaped lectures to…

Single nucleotide polymorphisms (SNPs) in DNA can result in phenotypes where the biochemical basis may not be clear due to the lack of protein structures. With the growing number of modeling and simulation software available on the internet, students can now participate in determining how small changes in genetic information impact cellular…

The advent of new educational technologies has stimulated interest in using online videos to deliver content in university courses. We examined student engagement with 78 online videos that we created and were incorporated into a one-semester flipped introductory mechanics course at the Georgia Institute of Technology. We found that students were…

The time evolution of quantum states is arguably one of the more difficult ideas in quantum mechanics. In this article, we report on results from an investigation of student understanding of this topic after lecture instruction. We demonstrate specific problems that students have in applying time dependence to quantum systems and in recognizing…

This study applied an unconventional use of past examination papers by converting questions into hands-on experiments for students. Students in an experimental group were engaged in use of those experiments while the remainder attended conventional lectures with written practice. The results reflect that the experimental group positively improved…

Aptitude treatment interaction (ATI) for the two most widely used science teaching strategies (lecture method and lecture method augmented with classroom activities) was investigated. The aptitude variables examined were cognitive ability level expressed in Piagetian terms and cognitive learning style (field independence/dependence). A sample of…

Compared are two approaches to inservice geology instruction for elementary and secondary school earth science teachers. The benefits of the combination of lecture, laboratory, and field work are emphasized. (CW)

This paper describes research using the Educational Resources Information Center--ERIC database to conduct a content analysis of education journals for science teachers. The journals analyzed: "Science and Children" (S&C), "The Science Teacher" (TST), and "The Journal of College Science Teaching" (TJCST), are used…
