This mixed methods study explored how elementary teachers reported using a commercially published instructional unit to plan and deliver science instruction in their elementary classrooms. Of particular focus is what elements of the program teachers eliminated during planning and instruction, what outside materials teachers added to instruction,…

There has been a growing emphasis on integrating green and sustainable chemistry (GSC) into the curriculum. Unfortunately, there is yet to be a nationwide, uniform decision of which aspects should be included or how, leaving individual instructors or institutions to decide whether--and how--to address GSC knowledge. Furthermore, faculty nationwide…

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…

This qualitative designed study explored teacher perceptions about science instruction. Three research questions were developed to guide the study. To facilitate the collection of data, the three research questions that guided this study were further broken down into ten interview questions. Purposeful sampling technique was used to select…

At universities across the United States the epistemological beliefs of students have been observed to deteriorate after a semester of instruction in an introductory physics course. What this indicates is that after taking a course in physics most students, for example, may become less capable of delineating between evidence-based reasoning and…

Recent calls in education have emphasized the critical need for curricula in the sciences to support student development of the general and disciplinary-specific practices that are relevant to modern scientific research and careers, as well as foundational scientific knowledge that reflects recent advances. In this regard, the life sciences,…

Chemistry is a highly abstract discipline that is taught and learned with the aid of various models. Among the most challenging, yet a fundamental topic in general chemistry at the high school level, is molecular geometry. This study focused on developing exemplary educative curriculum materials pertaining to the topic of molecular geometry. The…

The lack of time and attention dedicated to science at the elementary level is a problem that results in a missed opportunity to engage students in science at an early age, potentially perpetuating the gender gap at the secondary, college and career levels. There are many factors contributing to the lack of science education at the elementary…

Scientific explanations require levels of both precision and generality that are not characteristic of everyday thinking. For example, an equation such as F = ma can be used to make specific predictions across a wide range of situations. How can science instruction help students to appreciate the utility and importance of precise general…

Students majoring in science, technology, engineering, and mathematics (STEM) are in high demand. Over 1 million STEM graduates will be needed by 2022 to meet the projected workforce needs (The Progress Report on Coordinating Federal Science, Technology, Engineering, and Mathematics Education, 2016). If students are needed to fulfill jobs in areas…

This dissertation consists of two studies at the United States Military Academy. Both studies involve the use of Course-based Undergraduate Research Experiences (CUREs). These experiences give students the ability to engage in undergraduate research at an early point in their academic career by replacing traditional laboratory activities with…

Research is not clear on how to address the difficulty students have conceptualizing geologic processes and phenomena. This study investigated how animations coupled with seductive details effect learners' situational interest and emotions. A quantitative quasi-experimental study employing an independent-measures factorial design was used. The…

STEM educational reform encourages a transition from instructor-centered passive learning classrooms to student-centered, active learning environments. Instructors adopting these changes incorporate research-validated teaching practices that improve student learning. Professional development that trains faculty to implement instructional reforms…

This study investigated the design, enactment, and impact of an undergraduate, inquiry-based astronomy laboratory learning environment. The professor, Richard, adopted laboratory materials from the Center for Astronomy and Physics Education Research [CAPER] which were described by the group as inquiry-based. Students worked through these…

Growing demand for science teachers in the Kingdom of Saudi Arabia, fed by increasing numbers of public school students, is forcing the Saudi government to attract, recruit and retain well-qualified science teachers. Beginning science teachers enter the educational profession with a massive fullfilment and satisfaction in their roles and positions…
