In this study, we sought to examine the influence of a 12-week design-based elective Science, Technology, Engineering, and Mathematics (STEM) course on pre-service chemistry teachers' content knowledge, STEM conceptions, and engineering and engineering design views. To attain the goals determined, we utilized five STEM activities starting with a…

Concept inventories have been determined to be useful assessment tools for evaluating students' knowledge, particularly in the sciences. However, these assessment tools must be validated to reflect as accurately as possible students' understanding of concepts. One possible threat to this validation is what previous literature calls the item order…

This study examines the influence of laboratory instruction that engages students in a wide range of the practices of science on Turkish high-school students' chemistry learning. In this mixed methods study, student learning in two different laboratory settings was compared, one that featured an instruction that engaged students in a wide range of…

This case study seeks to explore three research questions: (1) What science teaching and learning processes, perspectives, and cultures exist within the science classroom of an urban portfolio community high school? (2) In what ways does the portfolio-based approach prepare high school students of color for college level science coursework,…

This study examined the effects of cooperative testing versus traditional or individual testing and the impacts on academic achievement, motivation toward science, and study time for 9th grade biology students. Research questions centered on weekly quizzes given in a flipped classroom format for a period of 13 weeks. The study used a mixed methods…

This study aims to determine the effect on the achievement, motivation and self-sufficiency of students of the flipped classroom approach adapted to Keller's ARCS (Attention, Relevance, Confidence and Satisfaction) motivation model and applied to a physics course. The study involved 66 students divided into two classes of a physics course. The…

Scientific argumentation has been greatly emphasized in the National Science Standard due to its ability to enhance students' understanding of scientific concepts. This study investigated the mastery level of scientific argumentation, based on Toulmin's Argumentation Model (TAP), when students engage in individual and group argumentations. A total…

Self-efficacy beliefs that relate to teachers' motivation and performance have been an important area of concern for preservice teacher education. Research suggests high-quality science coursework has the potential to shape preservice teachers' science self-efficacy beliefs. However, there are few studies examining the relationship between science…

This mixed methods study examined 73 5th graders' flow experience in a game-based science learning environment using two gameplay approaches (solo and collaborative gameplay). Both survey and focus group interview findings revealed that students had high flow experience; however, there were no flow experience differences that were contingent upon…
