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 crafted Bohr’s atomic representation on students’ academic performance in chemistry in Kayonza District, Rwanda
Abstract
The study was to investigate the impact of using crafted Bohr’s atomic representation as alternative chemistry resources on students’ higher order thinking and their effect on student’s academic performance. Using crafted Bohr’s atomic representation as instructional resource, a student improves learning skills to correct concepts misconception. The study is a quasi-experimental with pre-test post-test, experimental and control group design and it is quantitative. With a sample of 330 students that was calculated from a population of 24,523 students at one of districts in Rwanda, the students were placed into two group using non-random sampling technique and each group composed of 165 students. Findings revealed a higher increase in experimental group’s percent mean score than the control group’s suggesting a positive impact on higher order thinking, and for that reason, students exposed to the instruction using crafted Bohr’s atomic representation agreed at high level that exposure enhanced higher order thinking skill and positive interest in chemistry subject. It is suggested that crafted Bohr’s atomic representation may are developed using resources found around the school, as they improve students' academic performance.
