This study investigated the effect of explicit nature of science (NOS) instruction and explicit argumentation instruction in socioscientific and scientific contexts, on students' NOS conceptions and their argumentation skills. Undergraduate students enrolled in two sections of a science content course were assigned into two groups: Socioscientific…

Student motivational beliefs in introductory physics courses can influence their course outcomes as well as their retention in science, technology, engineering, and mathematics disciplines and future career aspirations. Prior research has shown that students' perceived recognition by others as a physics person is important in predicting their…

Studying students' problem-solving abilities in physics education research has consistently shown that novices focus on a problem's surface features rather than its physical principles. Previous research has observed that some electricity and magnetism students confuse electricity and magnetism concepts, often presented in parallel problems (or…

Background: Studies comparing the effect of dynamic and static visualization suggest a predominantly positive effect of dynamic visualization. However, the results of individual comparisons are highly heterogeneous. In this study, we assess whether dynamic visualization (3D models and animations) used in the experimental group has a stronger…

The Conceptual Survey of Electricity and Magnetism (CSEM) is a multiple-choice survey that contains a variety of electricity and magnetism concepts from Coulomb's law to Faraday's law at the level of introductory physics used to help inform instructors of student mastery of those concepts. Prior studies suggest that many concepts on the survey are…

Brain-Based Learning (BBL) is an educational theoretical framework based on principles that derive from important findings about the structure and function of the brain through biology, psychology, and neuroscientific research, and forms a holistic context for a comprehensive instructional approach design. In the present study, a teaching…

This study aimed at identifying the level of scientific argumentation skills in chemistry subject among Omani Grade 11th students and the effects of their logical thinking skills and gender on this level. The study sample consisted of (400) male and female students selected purposely from one educational region in Oman. The study's instruments…

Understanding the challenges and preferences perceived by learners is crucial in helping institutions devise strategies to support the continuum of learning during the COVID-19 pandemic. This study used photovoice to examine the barriers in the online learning engagement in chemistry of junior high school students in the lens of their experiences…

Good science teaching within an urban middle school context was examined in this qualitative methods study. This research also examined what middle school science teachers prioritized in an urban science classroom and uncovered ways in which culturally responsive teaching showcased itself among inservice teachers. Good science teaching and…

The purpose of this applied research study was to improve the use of three-dimensional pedagogy in science classes in chronically low-performing schools. The need to build teacher capacity became evident after the state adopted more rigorous science standards revealing deficits in teachers' pedagogical content knowledge. This study utilized two…

Professional development is essential for certified Teachers of students with Visual Impairments (TVIs) to create high-quality tactile graphics in school settings. The teachers need more opportunities to learn knowledge and skills from other teacher colleagues on a community basis. Few studies were conducted to investigate what community-based…

Science capabilities were introduced within the New Zealand context following the revised "New Zealand Curriculum" (NZC). These capabilities are a small set of things that NZC intends students to be able to do in science, which weave the nature of science with content strands. Using pedagogical content knowledge (PCK) to understand…

In this dissertation I explore characteristics which influence the implementation of evidence-based instructional practices of six post-secondary chemistry instructors in Colorado who report current use of these practices. The purpose of this study was to identify these characteristics to recognize areas of focus for future professional…

The emergence of COVID-19 significantly hindered student access to valuable university resources aimed at promoting engagement and academic success. The need to adapt the academic support services to a virtual environment also presented an opportunity to tailor these services to be more effective in chemical education. The primary goal of this…

This study investigated how prospective elementary teachers view themselves as learners of mathematics and science during their last year in a teacher preparation program at an American university. Using drawing and reflections as the method for collecting data, prospective teachers were prompted to draw themselves and reflect on learning…
