This study investigated the effectiveness of the orientation, identify, discussion, decision, and engage in behavior (OIDDE) learning model in enhancing biology learning outcomes, critical thinking, ethical attitudes, and engagement among high school students in Indonesia. Employing a quasi-experimental design with pre- and post-tests, the…

The processes of mitosis and meiosis are oft-cited and long-standing examples of concepts that are difficult for students to learn and understand. While there are many examples in the literature of "how-to-do-it," innovative instructional approaches for teaching mitosis and meiosis, publications that include measurement of learning gains…

Research points to the important role achievement emotions play in academic performance and career choices, yet few studies have examined achievement emotions in non-Western contexts. The current study extends this research base by examining students' achievement emotions among 103 eleventh-grade high school chemistry students in China. Using…

Middle school has been documented as the period in which a drop in students' science interest and achievement occurs. This trend indicates a lack of motivation for learning science; however, little is known about how different aspects of motivation interact with student engagement and science learning outcomes. This study examines the…

Numerous studies have attributed gender difference in mathematics achievement to various sociocultural influences. Singapore is a country of higher gender equality as represented in the Global Gender Gap Index and Singaporean girls perform as well or higher than boys in international mathematics assessments. This study develops a conceptual model…

Researchers have shown a growing interest in science teachers' professional knowledge in recent decades. The article focuses on how chemistry teachers impart chemical bonding, one of the most important topics covered in upper secondary school chemistry courses. Chemical bonding is primarily taught using models, which are key for understanding…

Background: Investigating factors contributing to chemistry achievement is important since it enables us to make more concrete instructional decisions related to improving students' chemistry achievement. Purpose: This study aimed to investigate how students' perceptions of learning environment, self-efficacy and gender are related to chemistry…

Teachers make a difference for the outcome of their students in science classrooms. One focus in this context lies on teachers' professional knowledge. We describe this knowledge according to three domains, namely (1) content knowledge (CK), (2) pedagogical content knowledge (PCK), and (3) curricular knowledge (CuK). We hypothesise a positive…

Background: Many researchers agree that students, especially primary students, have learning difficulties on the "Particulate Nature of Matter" unit. One reason for this difficulty is not considering individual differences for teaching science. In 4MAT model learning, environment is arranged according to individual differences. Purpose:…

The goals of a Liberal Studies education are designed to prepare citizens to live responsible, productive, and creative lives in a changing world. Ideally, a liberal education fosters well-grounded intellectuals with dispositions toward learning and an acceptance of responsibility regarding their ideas and actions. To measure the efficacy of a…

Large-scale studies, such as the Trends in International Mathematics and Science Study (TIMSS), provide data to understand cross-national differences and similarities. In this study, we aimed to identify factors predicting mathematics achievement of Turkish students by comparing to Australian students. First, construct equivalence and item bias…

The purpose of this paper is to evaluate the effectiveness of the 2009-2010 iteration of the Correlated Science and Mathematics (CSM) professional development program which provides teachers and principals experience with integrated and effective science and mathematics teaching strategies and content. Archival CSM data was analyzed via mixed…

This paper summarizes the findings of a twenty year old pre-engineering program that is aimed at improving both the recruitment and retention of under-represented students pursuing careers in Science, Technology, Engineering and Mathematics (STEM). The Wright Science Technology and Engineering Preparatory Program (STEPP) was initiated in 1988 for…
