An ability to engage in system thinking is necessary to understand complex problems. While many pre-college students use system modeling tools, there is limited evidence of student reasoning about causal relationships that interact in diverging and converging chains, and how these affect system behavior. A chemistry unit on gas phenomena was…

This dissertation explores the implementation of classical education in a non-classical charter high school, with a focus on science education using classical methodologies. Employing techniques like copy work, history-based science teaching (HBST), the Socratic method, and the Progymnastmata, astronomy, and chemistry were taught. To identify…

Estimating astronomical scales requires multiple complex mental processes, such as spatial thinking and interpreting large numbers. As such, it is a nontrivial question how these estimates can be most efficiently assessed. There is reason to believe that results from previous studies probing astronomical scale estimates are possibly susceptible to…

How do teachers elicit and sustain students' interest and engagement in science lessons? This paper answers this question in the context of Bhutan, where students' performance in science is low compared to other subjects, and where falling levels of interest in science are a concern. Like other countries in the Global South, a large proportion of…

For high school students to develop scientific understanding and reasoning, it is essential that they engage in epistemic cognition and scientific argumentation. In the current study, we used the AIR model (i.e., Aims and values, epistemic Ideals, and Reliable processes) to examine high school students' epistemic cognition and argumentation as…

We examined inquiry practices and types of knowledge presented along with paths of logical associations between inquiry questions as part of an open inquiry process. The study analysed high school biology students' scientific summaries of open inquiry processes. We found three paths of logical associations between inquiry questions -- preliminary…

Incorporating design in science programs has been shown to enhance science understanding, practices, and problem-solving skills. However, instructors and students typically struggle with fostering effective communication within a design-based course. With better communication scaffolding, students would learn more content and also become better at…

Background: Discourse is the teacher's principal pedagogical tool in class. Studies stress the importance of research on discourse in science education and demonstrate its cruciality for understanding science. Purpose: The purpose of this study was to investigate characteristics of the classroom discourse in lessons on physics. Sample: Classroom…

Although the empowerment of critical thinking (CT) has become an international concern that needs to be developed in the biology learning process for high school students, there still needs to be more relevant research literature. This study aimed to compare the effectiveness of implementing reading, questioning, and answering strategies…

The recent inclusion of the "Depth Study" in the New South Wales (NSW) Years 11 and 12 science curriculum has generally been well received by secondary science education leaders. The Depth Study is designed to present an opportunity for students to engage in inquiry-based learning (IBL). However, the integration of this new curriculum…

Many high school science teachers feel ill-equipped and ill-trained to adequately support the ever-increasing number of ESL/EFL students. The purpose of this qualitative single case study was to explore science teachers' perspectives of effective science teaching strategies, the challenges implementing science teaching strategies, and suggestions…

Past research has often shown a lack of student output in English medium instruction (EMI) classes (e.g., An et al., 2021; Lo & Macaro, 2012) and this study seeks to identify possible reasons. Guided by literature on wait time (Rowe, 1986) and teacher higher-order thinking questions (Chin, 2007), this study explores whether these two…

The topic of natural selection presents challenges to high school students since it requires understanding of an emergent process, which is a missing schema for most students. Many interventions for teaching natural selection have limited effect in bringing about substantial ontological conceptual change. This study evaluates the effectiveness of…

This study is aimed at developing students' scientific oral presentation competence and competence in questionand-answer sessions, through the scientific presentation instruction: focus on question-and-answer sessions (SPIQA). The SPIQA contained coping strategies for question-andanswer sessions, communication strategies, impromptu speech…

This research aims to implement the guided inquiry learning model to improve the understanding of concepts and critical thinking skills of Vocational High School (SMK) students. The quasi-experiment method with the randomized pretest-posttest control group design was used to obtain data from students of one of the Vocational High Schools (SMK) in…
