Availability of materials and data
An inherent principle of publication is that others should be able to replicate and build upon the authors' published claims. Therefore, a condition of publication in AJESMS is that authors are required to make materials, data and associated protocols promptly available to readers without undue qualifications in material transfer agreements. Any restrictions on the availability of materials or information must be disclosed to the publishing team at the time of submission. Supporting data must be made available to Editorial Board Members and reviewers at the time of submission for the purposes of evaluating the manuscript. Reviewers may be asked to comment on the terms of access to materials, methods and/or data sets; AJESMS reserves the right to refuse publication in cases where authors do not provide adequate assurances that they can comply with the publication's requirements for sharing materials.
After publication, readers who encounter refusal by the authors to comply with these policies should contact the AJESMS publishing team. In cases where we are unable to resolve a complaint, the matter may be referred to the authors' funding institution and/or a formal statement of correction may be published, attached online to the publication, stating that readers have been unable to obtain necessary materials to replicate the findings.

Effect of conceptual transformation on electrochemistry performance of high-performing high school learners in South Africa
Abstract
In the Ximhungwe circuit of the Bohlabela district in the South African province of Mpumalanga, learners studying physical sciences participated in wider research to establish the influence of a constructivist approach to learning on learners’ understanding of electrochemistry principles. The study examined how learners in high achieving schools (HAS) responded to the conceptual change teaching strategy (CCTS), also known as collaboration on their understanding of electrochemistry principles. The investigation implemented a non-equivalent pre-test and post-test control group quasi-experimental research design. The sociocultural theory, commonly referred to as Vygotsky's theory of social constructivism, served as the foundation for the study's theoretical framework. Using a table of random numbers, a sample of 51 physical sciences students in the 12th grade from two top-performing public schools in the circuit was chosen at random to take part in the study. Both a pre- and post-test were provided to the learners: the ECT (Electrochemistry Concept Test) and the CCEQ (Chemistry Classroom Environment Questionnaire). Students taught using the CCTS significantly outperformed students taught using the traditional teaching method (TTM) in terms of learning scientific conceptions related to electrochemistry, according to one-way between group analysis of covariance (ANCOVA) and post hoc analysis with a Bonferroni adjustment performed on ECT. A substantial correlation between performance and students' perceptions of their chemistry classroom setting was also found using Pearson Product-Moment Correlation. The study offers statistical proof of the value of social interaction and meaningful learning in raising students' grasp of electrochemistry.
