Undergraduate laboratory courses can provide opportunities for students to participate in science practices. This requires rethinking both curricula and instruction. Science practice--based courses require students to be positioned as epistemic agents, implying a shift in instructor role. Teaching assistants (TAs) are the primary instructors for…

A new perspective on chemistry learning could be the optimal learning moment of view based on flow theory. Optimal learning moments (OLMs) that occur when students experience high levels of interest, challenge, and skill at the same time were investigated in this study. Participants of the study were 47 pre-service science teachers. Data were…

Reflection on current practices is key to the transformation of teachers into reflexive practitioners. This study describes how design thinking was integrated in Schön's 'reflection in and on' model, to transform traditional teaching of Biology into constructivist learning. As a first step, the reflection model was used to identify limitations in…

In this article, we tackle the phenomenon of what seems to be a misunderstanding between science education theory and philosophy of science--one which does not seem to have received any attention in the literature. While there seems to be a consensus within the realm of science education on limiting or altogether denying the explanatory role of…

Nitrate is a crucial parameter for assessing water quality, owing to its dual function in ecological systems. These functions can be beneficial or detrimental depending on whether nitrate concentrations are low or high, respectively. The ultraviolet spectrophotometric method (standard as 4500-NO[subscript 3]--B) is a classic method for determining…

Preservice elementary teachers need to be able to engage young students in science practices but may not have extensive experiences with those practices. They also may have contrasting beliefs about them, which inform their teaching practice. To understand preservice teachers' beliefs related to science practices, we focus on the connections they…

This ethnographic cross-case study examines five teachers' year-long efforts to implement practice-based physics instruction within the unique organizational context of a no-excuses charter network. The teachers were attempting to adapt their didactic, rigid, and compliance-based instructional approach to include more opportunities for students to…

This study examined the effect of design-based science instruction (DBSI) on sixth grade students' science achievement, as well as their development in relation to science process skills. 213 sixth grade students from three public schools participated in the study. A pilot was conducted in the unit of Systems of the Human Body and the main study…

An essential aspect of scientific practice involves grappling with the generation of predictions, representations, interpretations, investigations, and communications related to scientific phenomena, all of which are inherently permeated with uncertainty. Transferring this practice from expert settings to the classroom is invaluable yet…

Many undergraduate chemistry and biochemistry students pursue careers in healthcare. Biomaterials, designed to harmonize with the complexity of the human body, have become increasingly significant in medicine as implants, drug delivery vehicles and tissue scaffolds. We believe it is essential that undergraduates are exposed to biomaterial…

This study investigates the effects of process-oriented guided inquiry learning (POGIL) on the academic performance and science process skills of Grade 10 Filipino students in science. Specifically, this study aimed to (1) determine and compare the level of academic performance of students when exposed to POGIL and non-POGIL and (2) assess the…

In this article we analyze the classic Hodgkin and Keynes 1955 paper describing investigations of the independence principle, with the expectation that there is much students and educators can learn from such exercises, most notably how the authors applied their diverse skill set to tackling the numerous obstacles that the study presented. The…

Chemical thinking has been widely recognized as a core competence for supporting students' problem solving in chemistry education. Disciplinary essential questions and perspectives are two critical aspects of chemical thinking. This study connects essential questions with such perspectives to develop a new framework for restructuring chemical…

This study contributes to the growing body of research on the role of crosscutting concepts (CCCs) in three-dimensional teaching and learning by examining the complexity of elementary preservice teachers' (PSTs) knowledge for teaching related to CCCs. The researchers used qualitative methods to analyze PSTs' responses to a questionnaire about CCCs…

The field of anatomy is often seen by nonanatomists as concerned primarily with the tasks of locating, naming, and describing structures; these tasks, in turn, are often assumed to require only lower-order cognitive skills (LOCSs), i.e., the Knowledge or Comprehension levels of Bloom's taxonomy. Many nonanatomists may thus believe that studying…
