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.
Sharing datasets
A condition of publication AJESMS is that authors make materials, data and associated protocols promptly available to others without preconditions.
Datasets must be made freely available to readers from the date of publication, and must be provided to Editorial Board Members and reviewers at submission, for the purposes of evaluating the manuscript.

Effectiveness of Practical Work in Physics on Academic Performance among Learners at the selected secondary school in Rwanda
Abstract
The current study investigates the effectiveness of practical work in physics on academic performance among learners of a secondary school in Rwanda. The study employs a quasi-experimental research design specifically pretest-posttest control group design (control group and experimental group). Two groups of learners of senior one at Groupe Scholaire Rugoma were treated differently through an expository and practice-based approach respectively. Physics achievement test prepared to evaluate the effect of practical work indicated that learners in the experimental group outperformed those of the control group treated by the expository teaching method. Various factors that may advance or hinder the implementation of practical work were identified and views from science teachers were collected. Most of the respondents strongly agreed that those factors have a significant impact on the implementation of practical work which in turn influence learners’ overall academic performance during Physics Achievement Test (PAT). A significant difference was observed from the statistical analysis performed by using SPSS version 21.0. (Pretest and posttest among learners in the experimental group; t = 27.243; 32.743; MD = 8.4239; 13.12500 respectively whereas the pretest and posttest among learners are as follow, t = 28.442; 32.627; MD = 9.82500; 2.38005 respectively and for all performance evaluation hypotheses were tested at .05 level of significance. Based on the observed results, it was found that practical work was more effective in improving learners’ performance in Physics. It was therefore concluded that practical work continues to be a promising approach in teaching sciences, particularly teaching Physics in secondary schools.
