The purpose of this study is to develop an up-to-date scale with high validity and reliability that could reveal the attitudes of high school students towards the physics course. In the process of developing the scale in question, three independent samples were formed, and the data obtained from a total of 1118 high school students were analyzed.…

Mathematical reasoning skills are a desired outcome of many introductory physics courses, particularly calculus-based physics courses. Novices can struggle to understand the many roles signed numbers play in physics contexts, and recent evidence shows that unresolved struggle can carry over to subsequent physics courses. Positive and negative…

We present a novel activity to demonstrate the Doppler shift of a sound wave, incident at an angle, upon a moving reflector. This activity is intended for use in an introductory physics laboratory focused on preparing students for the health and medical fields. The activity is designed to simulate Doppler velocity measurements from ultrasound…

Current K-12 and undergraduate students have grown up with constant exposure to visual popular culture (e.g., movies, TV programs, graphic novels, etc.). Because youth find pop culture references in the classroom to be engaging, many science and engineering instructors have shown that examples found in visual pop culture can be used to teach…

Computational thinking" (CT) is still a relatively new term in the lexicon of learning objectives and science standards. The term was popularized in an essay by Wing, who said, "To reading, writing and arithmetic, we should add computational thinking to every child's analytical ability." Agreeing with this premise, in 2013 the…

Each fall the Statistical Research Center (SRC) conducts its Survey of Enrollments and Degrees. The survey is sent to all degree-granting physics and astronomy departments in the United States and Puerto Rico. Departments are asked to provide information concerning the number of students they currently have enrolled and the number of degrees they…

Though extensively documented, the exact mechanism responsible for pattern formation on insect bristles and scales is not completely understood. Using both scanning and transmission electron microscopy, we assemble a rough time series of pattern formation on butterfly wing scales. We also perform a numerical simulation of the Swift-Hohenberg…

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…

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…
