Assessment in education involves collecting and processing information related to student achievement during learning. Assessment activities help educators to find out where learners are having difficulties which for the sake of completeness requires an integrated instrument. The assessment carried out should conform to 21st-century learning…

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…

Students' lack of interest in chemistry becomes a significant issue in chemistry learning. This may be caused by the negative perception of students about their difficulties in learning chemistry. This study aims to explore views and causes of difficulties in learning chemistry from the perspective of secondary school students. This research was…

This study, titled "The Effect of Computer Simulation on Grade 11 Learners' Conceptualisation of Stoichiometric Chemistry," was carried out at a school in the Frances Baard District of the Northern Cape province of South Africa. Poor conceptualisation of stoichiometric chemistry by learners in Grades 10-12 in South Africa and, hence,…

This study aims to determine the feasibility of Instagram-based chemistry learning media and the results of increasing student interest in learning acid-base material in everyday life with a multi-representation approach. The method used in this study is the ADDIE research and development model (Analysis, Design, Development, Implementation, and…

As the world becomes increasingly rooted in all forms of inequities, so does the need to fight its causatives. This study is concerned with ensuring that science education serves to reinforce gender equity against traditional narratives. We explored the potency of culturo-techno-contextual approach (CTCA) in leveling the playing field while…

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 study explores the integration of socio-humanitarian safety components into the chemistry curriculum for secondary education, emphasizing how contextual and competency-based assessments can enhance the preparedness of future chemistry teachers. Employing a mixed-methods approach, the research evaluates the effectiveness of traditional,…

We present an example of a novel, model-based approach to instruction in which learners constructed a representation of a specific phenomenon, evaluated their representation, and then revised it, via an abstraction process, to construct a model. The example took place in high school in the context of solution chemistry. The aim of the instruction…

The purpose of this study was to determine the effect of topic-specific pedagogical content knowledge-based instruction on grade 11 students' achievement in chemical kinetics and equilibrium. A quasi-experimental research design with a 4 × 2 * 3 pre-test and post-test control group was employed on Grade 11 chemistry students in Addis Ababa…

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…

Many researchers have reported that bridging analogies can productively support students' scientific meaning-making. How this can be understood semiotically is, however, not well understood. This research followed an ethnographic case study approach to investigate Year 11 students meaning-making through a process of transduction (Kress, 2000;…

This study focuses on examining the mental models of 11th and 12th-grade students attending a science high school in Turkey regarding the concept of the electron cloud. The study involved 72 students and employed the case study method. The precondition for selecting the sample was that the students had covered the unit on modern atomic theory in…

The rapid evolution of Artificial Intelligence (AI) is profoundly shaping our society. Among various AI tools, ChatGPT stands out for its user-friendly nature and wide accessibility to the public. However, despite their countless potential benefits, these tools also face significant challenges, especially in sensitive areas like Education. In this…

This research focuses on chemistry teachers' enacted pedagogical content knowledge (ePCK) in equilibrium in chemical reactions. The enactment dimension of this pedagogical content knowledge (PCK) encompasses enacted knowledge and skills as well as those embedded in practice concerning the Refined Consensus Model of PCK, the most recent PCK model…
