The study complements previous research on a case study of chemistry lesson plans design and teaching. It has been found that chemistry education in the Gambia has been challenged by ineffective lesson plans design and teaching, and laboratory resources. The consequences have been unsatisfactory learning outcomes. However, what could lead to…

This study aimed at examining the performance of generative artificial intelligence to extract argumentation elements from text. Thus, the researchers developed a web-based framework to provide automated assessment and feedback relying on a large language model, ChatGPT. The results produced by ChatGPT were compared to human experts across…

The redox reaction is a core concept of upper-secondary school chemistry curriculum. Accurate diagnosis of students' conceptual understanding of the redox reaction from a cognitive structure perspective is critical for enhancing their understanding of chemical concepts. This study utilized Bayesian networks to investigate the cognitive structures…

This quasi-experimental study was conducted in two secondary schools in a major city in the United Arab Emirates (UAE) to examine the impact of Computer Simulations (CSs) on students' learning of Newton's Second Law of Motion (NSLOM) in grade 11 compared to traditional face-to-face education. The study used Newton's Second Law of Motion…

The role of motivation in chemistry learning has long been explored and has become an exciting research topic worldwide. The aim of this study was to explore whether gender, class and students' anxiety influenced the motivation to learn chemistry among upper-secondary school students in Indonesia. The Chemistry Motivation Questionnaire II and the…

The technological, pedagogical and content knowledge (TPACK) framework was developed incorporating content, pedagogical and technological knowledge. Studies used TPACK constructs and reported on teachers' TPACK and student learning, but none explored the correlation between teachers' TPACK and the achievement of their learners. This research…

Students' attitude towards a subject is a key indicator of academic performance, therefore its enhancement is imperative for academic success. A sample of 328 grade eleven students was selected using cluster random sampling. Two different study groups; the experimental and control groups, were composed and exposed to the guided inquiry and…

Student understanding of chemical equilibrium in aqueous solutions (CEAS) plays a vital role in their upper secondary school chemistry learning and everyday life. Diagnosis of students' alternative conceptions (ACs) of the CEAS will provide teachers with valuable information to make instructional decisions on student learning. This study aims to…

One of the skills needed in the 21st century is critical thinking skills that need to be developed for secondary school students. Currently, upper-secondary students' critical thinking skills are still low. To overcome the problem, websitebased E-module learning media was developed using a STEM approach with a Problem-Based Contextual Learning…

Visuo-semiotic models, such as Lewis structures and ball & stick models, are widely used to enhance students' learning. However, there is limited research about the impact of these models on specific visuo-semiotic reasoning skills. In the current research, we aimed to determine the extent to which physical molecular models could enhance…

Besides improving students' understanding of scientific concepts, chemistry teaching should also improve students' ability of applying concepts to solve problems. The research aims to explore the effects of modeling teaching on students' proficiency in solving galvanic cell problems. This research used a quasi-experimental design, and the…

Science educators have highlighted the need to develop students to integrate knowledge across science disciplines to address real-world issues. However, there has been little research about the development of interdisciplinary assessment instruments. In this research, the instrument that measures the level of upper-secondary school students'…

Teachers use different pedagogies to improve learners' performance. The study explored the effect of Computer Simulations (CS) on Grade 11 learners' performance when taught Plants Biodiversity. A Solomon FourGroup design was used to cater for internal and external validity. Sixty-six learners were assigned to two Control Groups (CG) taught using…

Learners underperform in stoichiometry as they lack conceptual reasoning of the underlying concepts and the ability to solve stoichiometric problems. Therefore, it was necessary to determine if there is a statistical correlation between problem-solving skills and conceptual reasoning in stoichiometry and if so, whether one can significantly…

Preparing a positive attitude toward convergence is essential to help students grow into future generations with the ability to solve various complex problems. This research aims to examine high school students' attitude toward convergence and the relation to gender and track. Responses from 1,186 Indonesian students in tenth (10th) and eleventh…
