The topic of natural selection presents challenges to high school students since it requires understanding of an emergent process, which is a missing schema for most students. Many interventions for teaching natural selection have limited effect in bringing about substantial ontological conceptual change. This study evaluates the effectiveness of…

The growing adoption of active learning techniques in physics courses requires that students productively engage in collaboration with their peers. Although studies in physics education research (PER) have addressed aspects of group work, the problem persists of how to engage students in collaborative work with appropriate self-awareness, adequate…

To investigate how physics students perceived the sudden shift to online learning at the beginning of COVID-19 pandemic, 18 semistructured interviews were conducted with university students in Austria, Croatia, and Germany. Based on the interviews, a questionnaire was developed and data from N ¼ 578 physics students from five universities in…

Peer argumentation, especially the discussion of contrary points of view, has experimentally been found to be effective in promoting science content knowledge, but how this occurs is still unknown. The available explanations are insufficient because they do not account for the evidence showing that gains in content knowledge are unrelated to group…

Organic Chemistry is considered by many to be the quintessential "weeder course", widely identified in the premed and STEM persistence literature as a gatekeeper to students interested in STEM or health fields (Barr, Gonzalez, & Wanat, 2008; Lovecchio & Dundes, 2002). There has therefore been considerable interest in determining…

Emphasizing scientific literacy in the core science curriculum promotes informed students within a liberal arts education. In our Introduction to Biology course, which enrolls predominantly humanities majors in their final science course of their academic careers, we designed a project to advance these analytical processes through the deliberate…

This experiment is dedicated to second-year and above undergraduates who are in their experimental session of the analytical chemistry course. Grouped students are required to use a TiO[subscript 2] photocatalytic oxidation process to treat the methanol-containing wastewater that resulted from their previous HPLC experiments. Students learn to…

This study investigates the effectiveness and knowledge retention of elearning models that could solve education problems in rural areas by considering two different examples: massive online open courses (MOOCs) and gamification hybrid learning. The study also proposes suitable and effective features that could influence student abilities in the…

Over the last few decades, there has been an international focus on productive talk in science classrooms, requiring teachers to use more dialogic practices with their students. Studies promoting a dialogic approach propose that students have conversations in small, student-led groups. However, the literature in education and science education…

Developing students' ability to troubleshoot is an important learning outcome for many undergraduate physics lab courses, especially electronics courses. In other work, metacognition has been identified as an important feature of troubleshooting. However, that work has focused primarily on "individual" students' metacognitive processes…

The purpose of this study was to explore high school students' ideas regarding two theoretical scientific models, either electron cloud or sodium chloride crystal, in the context of active learning in small groups. Conversations among peers regarding these models took place during two types of active learning activities: small-group discussion and…

Enzyme purification, characterization, and identification are some of the best ways to introduce undergraduate students to many aspects of biochemistry, particularly as part of project-based learning (PBL). These kinds of multi-step laboratory experiments not only help students to better understand basic biochemistry concepts but also serve to…

Combinations of text and different types of pictures are commonplace in biology as in science in general. The single representations (i.e., text, picture) constituting a text-picture combination may contain redundant or complementary information. The ability to identify and integrate information in different kinds of text-picture combinations is…

This article presents an empirical analysis of conceptual difficulties encountered and ways students made progress in learning at both individual and group levels in a classroom environment in which the students used an embodied modeling activity to make sense of a specific scientific scenario. The theoretical framework, coordination class theory,…

This article examines how students taking a post-compulsory physics course for 16- to 19-year-olds (A-level physics) benefited from a change in pedagogy which meant that they spent more time problem solving in collaborative groups. Video analysis of these collaborative problem-solving sessions revealed that the students improved a number of key…
