Working with approximations is a common practice in physics. This paper presents an exploratory study of student understanding of some of the elementary aspects of approximations encountered in college physics. For this purpose, a questionnaire (a set of 14 multiple-choice questions) was developed to probe how students dealt with these aspects in…

The limited availability of research instruments that reflect the vision of the Next Generation Science Standards (NGSS) restricts the field's understanding of whether and how teachers are making instructional shifts called for by the standards. The need for such instruments is particularly urgent with teachers of multilingual learners (MLs), who…

A didactic sequence is proposed using an infrared puzzle and a didactic questionnaire for the teaching-learning of infrared spectroscopy at the upper secondary level. The didactic sequence that was designed was implemented in person in the subject of Chemistry IV at the high school level, corresponding to the sixth semester of the curriculum of…

Background: Teachers' views of nature of science (NOS) play a key-role in how they teach science and can significantly impact their students' understanding of and achievement in science. NOS has been a curriculum goal in science education for several decades. Therefore, there is a need for assessment tools that can examine views of NOS in the…

This study investigates associations between two types of control beliefs--self-efficacy for self-regulation and implicit theories of willpower--and undergraduate biology students' (N = 535) behavioral self-regulation and performance. Findings suggest that self-efficacy is the more proximally related motive for students to engage in academic…

The alternative conceptions that students hold put a brake on subsequent meaningful learning, and therefore, the identification of these wrong ideas is crucial for effective teaching and academic success. Undergraduate STEM students often perceive Chemical Thermodynamics as a difficult subject, in which entropy has been pointed out as a threshold…

Clear and rigorous quantum reasoning is needed to explain quantum physical phenomena. As pillars of true quantum physical explanations, we suggest specific quantum reasoning derived from quantum physical key ideas. An experiment is suggested to support such a quantum reasoning, in which a quantized radiation field interacts with an optical beam…

The teaching and learning of quantum physics has recently become a topic of increasing interest in physics education research. In particular, the study of two-state systems is gaining importance as a means of teaching quantum physics at various educational levels. Meanwhile, a number of approaches have been developed that are also suitable for…

This study investigated the predictive effect of in-service and pre-service science teachers' perceptions of the learning environment on their self-efficacy beliefs on science teaching. The same self-report questionnaires were used to collect data from in-service and pre-service science teachers. Of the participants, 142 in-service science…

Grades in introductory STEM courses can impact intrinsic motivation (IM) and self-efficacy (SE). We used an exploratory approach to examine trends in grades and how IM and SE impact students' grades. It is known that most first-generation (FG) college students are from underrepresented backgrounds (URM), and that these students are least likely to…
