Conceptions of ecological processes such as the flow of energy and cycling of matter in an ecosystem are increasingly important understandings in a rapidly changing world. This study utilizes a p-prims, or knowledge in pieces, lens to examine understandings and disconnections in students' conceptualizations of energy flow and matter cycling…

The aim of this study was to identify the content of secondary Science curriculum excluded in teaching and learning activities, the reasons behind the omission and its impact on students' learning in the context of Bangladesh. This study used qualitative methodology. Eight teachers were selected and interviewed to investigate what they excluded…

This research is conducted among 65 seventh graders (12-14 years old) who attend introductory course on physics. Tests and interviews are used to trace the roots of the students' misconceptions about mass. Results from the research reveal serious weaknesses in students' understanding of concept of mass, and its confusion with concepts of density…

Undergraduate research experiences have been adopted across higher education institutions. However, most studies examining benefits derived from undergraduate research rely on self-report of skill development. This study used an empirical assessment of research skills to investigate associations between undergraduate research experiences and…

This study investigated the knowledge and skills that biology students may need to help them understand statistics/mathematics as it applies to genetics. The data are based on analyses of current representative genetics texts, practicing genetics professors' perspectives, and more directly, students' perceptions of, and performance in, doing…

The heart of learning chemistry is the ability to connect a compound's structure to its function; Lewis structures provide an essential link in this process. In many cases, their construction is taught using an algorithmic approach, containing a set of step-by-step rules. We believe that this approach is in direct conflict with the precepts of…

The study aims to characterize contextual learning during class visits to science and natural history museums. Based on previous studies, we assumed that "outdoor" learning is different from classroom-based learning, and free choice learning in the museums enhances the expression of learning in personal context. We studied about 750 students…

This study focused on informal reasoning regarding socioscientific issues. It sought to explore how content knowledge influenced the negotiation and resolution of contentious and complex scenarios based on genetic engineering. Two hundred and sixty-nine students drawn from undergraduate natural science and nonnatural science courses completed a…

To reduce curricular fragmentation in science education, reform recommendations include using common, unifying themes such as scaling to enhance curricular coherence. This study involved 215 participants from five groups (grades 5, 7, 9, and 12, and doctoral students), who completed written assessments and card sort tasks related to their…
