A comparison of student performance in an introductory biology class that used a lecture-based approach (N = 15 classes; 462 students) with those that had a no-lecture approach (N = 9 classes; 238 students). All classes were taught by the principal researcher. In the no- lecture environment, shifts in student perceptions of science were…

Active learning has often been reported to improve student outcomes in STEM courses. However, there are barriers to its implementation, and it is challenging to include this approach in large classrooms with fixed seating. This investigation explores the development of a novel approach in which the class contact time was reallocated for a general…

Breadth and depth of curriculum are important for success in science teaching and learning. Curriculum theorists recommend less breadth and more depth than overloaded, superficial science curricula. This study investigates breadth and depth in the official biology syllabi in the seventh to eighth or ninth years in four diverse jurisdictions,…

Effective science education is crucial for developing a scientifically literate citizenry, and for many, foundational primary science education experiences play a significant role in defining their long-term science trajectories. However, primary science education has been limited by a dissonance between the poor science trajectories for…

The purpose of this study is to "meta"-analytically evaluate research that used chemical bonding-based interventions to improve academic performance. Through "meta"-analysis, the present study used several keyword patterns (e.g., chemical bonding, experimental, chemistry education, science education) via relevant databases…

This study examined the effect of design-based science instruction (DBSI) on sixth grade students' science achievement, as well as their development in relation to science process skills. 213 sixth grade students from three public schools participated in the study. A pilot was conducted in the unit of Systems of the Human Body and the main study…

This study explored the effects of explicit and implicit epistemologically enhanced instructions probing 9th-grade students' personal epistemologies on their physics-related personal epistemology (PPE) and physics achievement in the heat and temperature unit. In the implicit epistemologically enhanced instruction (IEEI), different dimensions of…

Assessment plays a critical role in instruction and curriculum. Existing literature on instructors' assessment practices and related factors has been intensively focused on primary and secondary education. This study extended the contexts of previous literature to post-secondary chemistry education by exploring general chemistry instructors'…

The quality and effectiveness of online teaching-learning are increasingly important with online learning becoming the norm. This cross-sectional survey study aimed to determine the relationship between first-year polytechnic students' perception of chemistry asynchronous lectures and their learning performance. Their perception was determined…

Inquiry-Based Teaching Practice (IBTP) is an essential component of science education, and promoting its implementation is at the heart of various reform efforts. Even though science teachers regard IBTP as an essential pedagogical method, they rarely use it for various reasons. This study utilizes Bronfenbrenner's ecological framework to examine…

The jigsaw model is a dynamic cooperative learning approach where students become experts on different segments of the material and teach their peers, thereby enhancing engagement accountability, team work, and ultimately improving academic achievement. This study investigated the effectiveness of a cooperative learning strategy on secondary…

Research purposes and design: This study aimed to compare the effects of different explicit approaches used in modeling-based instruction on students' understanding of scientific models and modeling (USMM). In Study 1, a self-study approach was compared to a preliminary explicit approach. In Study 2, preliminary explicit approach and embedded…

The objectives of this research are: (1) to develop a flipped classroom learning plan using inquiry-based learning on the topic of substance separation for Grade 8 students, to achieve effectiveness according to the 75/75 criteria; (2) to compare science process skills and learning achievement before and after implementing the developed learning…

This comparative study investigated the effect of supplementing problem-based learning (PBL) with video resources on students' academic achievement in physics, a unit of simple machines. It was carried out in the Ugandan Government and private lower secondary schools. The quasi-experimental design employed a cluster sampling design with 947…

This study investigates the impact of constructivist teaching methods on achievement and misconceptions in mechanics, with a focus on gender differences. The research involved 88 first-year physics students enrolled in the physics teacher training program. Using a quasi-experimental design, students were divided into experimental (constructivist…
