This study aimed to explore Cooperative Learning theories and practice by examining the relationships among three aspects: Experience, Practice and Perceptions. The data were from interview records from eight science teachers. As a student-centered active pedagogical trend, cooperative learning has become part of one of the most effective and…

Next Generation Science Standards (NGSS) were developed by 26 lead states with NSTA, AAAS, NRC, and Achieve in 2013 to provide a new vision for the teaching of science in U.S. schools. Teachers' applications have been mainly concentrated on efforts to align the current practices with the standards. Elementary science teachers need to use…

This is a study of teachers transition after a professional development (PD). The purpose was to document and characterize the teachers' experiences as they transitioned toward use of the Next Generation Science Standards (NGSS) and more learner-centered teacher practices. The teachers participated in a PD workshop that provided information on the…

Efforts to improve student learning in K-12 education in the US are not new; however, educational research has traditionally focused on individual components of schools (e.g., teacher professional development, leadership, social relationships, programs, curricula) targeting teachers to improve student learning. While these innovations provide hope…

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…

Science classrooms continue to privilege narrow conceptions of science, and students of color are frequently identified by teachers as disengaged or uninterested in science--part of a deficit narrative socially constructed over time. In this design-based research study, I explored the development and implementation of culturally relevant and…

The purpose of this study was to create a culturally relevant, inquiry-based science lesson plan and examine how I can become a more culturally relevant educator. This was done first through the use of seminal frameworks in both pedagogies to examine similarities and differences. Secondly, eight experts in the fields were interviewed to gather…

The purpose of this qualitative action research study was to describe a middle-level science teacher's transition to an inquiry-based, progressivist, student-centered model from a traditional, teacher-centered model as well to document the student-participants' perceptions of the new model. The study population consisted of one-hundred…

A mounting body of evidence has shown that student-centered instructional practices are more effective than traditional teacher-centered methodologies in Undergraduate STEM courses. Several studies have shown the effectiveness of student-centered pedagogies through increases in student performance, retention, and higher achievement by…

This research presents the investigation of physics students' and physics faculty members' professional development and a design methodology via which we could best support them in their professional development. In particular, the first part of this dissertation will focus on undergraduate upper-division physics students' conceptual learning and…

The purpose of this study was to identify essential features of Epistemic Orientation toward Teaching Science (EOTS) and to explore the relationships between EOTS and instructional practices. This study proposes a new concept, EOTS: defined as a teacher's set of interrelated beliefs that are developed and used when teaching science, and are shaped…

Community college instructors are influential in the lives of rural students, and they have key insights on the education of those students. Studies are needed to identify ways to support these rural students, who represent an important source of political and socioeconomic diversity for their communities and when transferring to universities.…

My study was to discover the perceptions of general secondary senior high school biology teachers about the application of curriculum 2013. Their further opinions of biology topics and the instructional practices in the class have supported the findings of this study. In addressing this study, general senior secondary school (GSSS) biology…

The dissertation, with a collected papers approach, focused on evaluating the implementation of MI curriculum in high school Biology I classes in south Florida. The dissertation included the development and validation of the Biology Identity and Persistence Survey (BIPS), the connection of instructors' teaching practices with students' biology…

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…
