One expected outcome of physics instruction is that students develop quantitative reasoning skills, including strategies for evaluating solutions to problems. Examples of well-known "canonical" evaluation strategies include special case analysis, unit analysis, and checking for reasonable numbers. We report on responses from three tasks…

How science is traditionally taught and presented in westernized classrooms, Western Modern Science often does not offer creative and culturally sustaining pathways for students with diverse multicultural backgrounds to view science as a beneficial resource for their worldview, values, and funds of knowledge. This conceptual position paper…

Background/purpose: This study aimed to identify the impact of teaching science based on John Zahorek's model on the acquisition of scientific concepts among seventh-grade female students. Materials/methods. It was based on the quasi-experimental method. The study participants, comprising 58 seventh-grade students, were intentionally selected from…

Virtual classrooms based on the metaverse or virtual reality are useful and effective for imparting basic chemistry concepts. Interactive and immersive environments can effectively teach fundamental chemistry concepts, such as chemical bonding and formulas, thereby making these otherwise abstract and intangible ideas more accessible and…

My thesis work is focused on conceptual and epistemic learning and characterizing the environments in which this learning takes place. Earlier studies conducted by the Stowe group explored how instructional practices, instructional emphasis, and assessment emphasis relate to student outcomes in general and organic chemistry courses. Student…

This study investigates how preservice elementary teachers (PSTs) engage and reflect on two science disciplinary practices: engaging with representations and engaging in evidence-based arguments. In the context of elementary science, teachers blend multiple practices across curricular topics and instruction. However, studies of teachers' use of…

Background: As prospective teachers traverse the early stages of their careers, their first experiences of teaching (both in-course and in-classroom), and the transitions between them, need to support the growth of their professional learning. In the context of STEM education, more needs to be understood about pre-service teachers' lived…

This study reports on eleven second-year teachers who were all students in the same practice-based secondary science methods courses framed around ambitious science teaching. In this qualitative embedded single case study, we examined if, how, and why novice teachers linked their current critical pedagogical discourses and instruction back to any…

The work in this dissertation is presented in two parts. The first part (Chapters 3 and 4) details work relating to students' explanations of reaction mechanisms in organic chemistry. The second part (Chapters 5 and 6) details work relating to the evaluating the uptake of research-based instructional practices in introductory chemistry,…

Vocabulary knowledge plays a critical role in supporting text comprehension and broader learning across the school day. While school offers opportunities to build vocabulary knowledge, studies have shown that very little time is devoted to vocabulary instruction at the elementary level. This may be, in part, because educators commonly report being…

Science teacher education literature has emphasized the importance of prospective teachers' prior knowledge of their K-12 experiences as a key factor influencing their professional development as future science teachers. The purpose of the study was to identify the teaching practices in prospective teachers' prior knowledge of science instruction…

Understanding teachers' experiences as they lived them and as they told them is important for conceptualizing a well-rounded view of the state of science education and the role teachers play in it. Journey mapping, a way of visualizing one's processes and experiences as they progress towards a goal, is a tool with the potential to capture…

This study investigates preschool teachers' considerations for including digital tools in science teaching to develop children's learning of science content. Due to the ongoing digitalisation and demands in society, the utilisation of digital tools has increased significantly in educational settings. Recent research about digital tools in early…

Inquiry-based instruction has played an important role in science education, and been recognized as a critical approach to improve students' scientific learning effectiveness. However, current research revealed that it is a challenge for teacher education programs to improve pre-service science teachers' inquiry-based instructional activity design…

This study examined the early implementation stages of the Modeling Method of Instruction (MMI) in the science classroom to find the most valuable strategies for effective implementation. In this qualitative study, eleven teachers were interviewed to uncover effective implementation strategies. Interview data were analyzed using the constant…
