We investigated the effects of in-game learning supports' timing in a game called Physics Playground where we randomly assigned 149 students (M[subscript age] = 14, SD = 0.96) to receive learning supports either Before (n = 50) or After (n = 46) playing game levels--a no-support Control (n = 53) condition was included. We found that students…

Knowing about the evolution of atomic models throughout history is a fundamental topic to learn about atomic structure. This paper describes how identifying keywords from a musical YouTube video provides a stimulating activity for learning this topic in a chemistry class in middle school. The main goal was to show how a fun and interesting…

Abundant research leaves little question that pedagogical approaches involving active student engagement with the material, and opportunities for student-to-student discussions, lead to much better learning outcomes than traditional instructor-led, expository instructional formats, in physics and in many other fields. In introductory college…

This dissertation focuses on three manuscripts all related to bolstering science achievement through recommendations from the National Research Council (NRC) regarding the teaching and learning of science. The manuscripts address meeting the NRC's call to incorporate curriculum and assessment that lead to more in-depth knowledge that can be…

Framed in an interpretative phenomenological approach, this study explored the role of teaching subject (i.e. discipline) in Iranian teachers' online identity construction during the COVID-19 pandemic. Data were collected from teachers of hard and soft sciences through semi-structured interviews, reported practices and online interactions. Data…

This study examines the often-heard assumption in science teaching that some pedagogies in science classrooms can serve a dual function--improve the student-perceived teacher quality and improve students' affinity to STEM professions. We asked 7507 freshmen from 40 colleges in the United States, selected in a stratified random procedure, to…

The world lived through a pandemic over the 2020-2022 period, which forced drastic changes in every sector and every aspect of our lives. One such change in the education sector was the immediate shift to online learning as educational institutions across the world responded to the pandemic. Educational institutions in Trinidad & Tobago, like…

Rural Mississippi schools often face challenges in providing equitable access to Advanced Placement (AP) courses, particularly in STEM fields. This lack of access limits opportunities for high-achieving students to pursue rigorous STEM coursework and related careers. The AP STEM program aims to improve access to AP STEM courses for high-achieving…

The purpose of this study was to examine the relationship among pre-service science teachers' global scientific literacy and various variables within the scope of the structural equation model. Since the relations among the variables were investigated in the structural model established for this study, correlational research methodology was…

The role of ChatGPT and higher-order thinking skills (HOTS) as predictors of physics inquiry among uppersecondary students has yet to be widely explored. Therefore, this research aimed to examine upper-secondary students' role in ChatGPT (convenience and quality (CQ), motivation and engagement (ME), and accuracy and trust (AT)) and HOTS as…

Recognized as one of the most beautiful experiments of all time, the oil drop experiment performed by Robert Millikan and his graduate students (primarily Harvey Fletcher) is a standard in the repertoire of experiments performed by undergraduate physics students. However, "as a teaching lab it does not enjoy a good reputation for three…

Videos created with the hands of teachers filmed have been perceived as useful educational resource for students of Physics in undergraduate courses. In previous works, we analyzed the students' perception about educational videos by asking them about their experiences. In this work, we analyze the same facts, but from a learning analytics…

This article examines the impact of a professional development program aimed at encouraging high school teachers to include more modern physics in their enacted classroom curricula through improved content and pedagogical knowledge. The program was implemented with 17 high school physics teachers (three were the focal point of this study) in…

In common with many other countries, the Iranian science curriculum does not introduce primary children to atoms and molecules but instead leaves the teaching of these concepts until high school. This paper challenges this practice and describes the changes in elementary Iranian children's understanding of atoms and molecules following a 10-h…

The objective of this article is to identify and discuss the views of teachers of physics-chemistry (Ph-Ch) and Life and Earth Sciences (LES) on the use and effectiveness of interactive simulations PhET (Physics Education Technology) in student teaching and learning. A survey research method was used in this study. 114 Moroccan science teachers…
