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'…

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…

Peer-led team learning is a socially mediated pedagogy where trained peer leaders, students who have completed a course, return to lead students in groups within a targeted course. The effect of peer-led team learning to improve student success in chemistry has been extensively documented but it is unclear if it is just as effective at…

The purpose of this study is to examine the effects of employing an augmented reality (AR) lens imaging system on inquiry-based learning concerning junior high school students' science achievement, science learning motivation, and inquiry skills. For this purpose, an AR lens imaging learning system was developed specifically for the lens imaging…

This study investigated the use of collaborative instructional approaches on form two science students' performance in redox reactions. The sample for this study consisted of 106 science students from Winneba Senior High School in Ghana. The sample was selected from two intact classes in the school. After a pre-test organized for both classes, the…

The purpose of this study was to investigate the effect of the case-based learning (CBL) method used in "biochemical oxygen demand (BOD)," which is a topic taught in the environmental chemistry course, at Dokuz Eylul University, on the academic achievement and opinions of students. The research had a quasi-experimental design and the…

This study aimed to uncover common difficulties and possible areas for improvement by focusing on the approaches and errors made by 3rd-year undergraduate chemistry students in solving organic synthesis problems. The study employed a purposive sampling technique to select 112 undergraduate chemistry major students to participate in this study.…

The purpose of this study was to examine whether a simulation-integrated context-based 7E instructional strategy (SICBIS) could increase students' achievement in the chemistry of oxides, acids, bases, and salts (COABS) when compared to context-based 7E instructional strategy (CBIS), simulation-integrated conventional teaching approach (SICTA), and…

Online learning is a well-established and growing, yet controversial and widely criticized, component of higher education. In this study, in-person and online versions of an undergraduate introductory biology class were compared to determine whether the online version of the course promoted student performance as well as the in-person course.…

The paper is about a study that investigated how the integration of assessment for learning enhances learning achievement among secondary school biology students in Tanzania. A quasi-experimental design involving pre-test and post-test of non-equivalent control and experimental groups was used to ascertain how the integration of assessment for…

Two generative approaches to reaction mechanism instruction for novice students were compared to lecture instruction. In both approaches, students were coached to propose selected reaction mechanisms based on prior knowledge. New instructional methods were correlated with increased skill in representations of electron movements and other gains.…

Previous research has shown the validity of the Measure of Linked Concepts (MLC) assessment in college introductory chemistry. Herein, we present a novel model of pairing the MLC with a metacognitive exercise aligned with learning objectives in the introductory chemistry courses as an effective tool for instructors to be integrated into…

This study aimed at designing a framework to help students develop a conceptual understanding of redox reactions, which draws on constructivist learning theory. This framework was in the form of participatory teaching and learning approach comprising Insight, Interaction, Task, and Forum. The framework was designed and developed based on the…

This mixed methods study focuses on the use of instructional videos in an undergraduate physics classroom. Previous research has explored the effects of videos on student performance however, limited research exists on the effects of science instructional videos with embedded quiz questions on student achievement. This study compares students'…

This paper reports on the relationship between the pre-service teachers' enacted Topic Specific Pedagogical Content Knowledge (eTSPCK) observable in the classroom teaching of Organic Chemistry and learner achievement in the topic. The study employed a mixed-methods research design with a sample of 17 pre-service teachers (PSTs). The PSTs were…
