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.

Effects of sequenced experimentation on trainees’ understanding of concepts in analytical chemistry
Abstract
The study involved 12 undergraduate teacher trainees who embarked on several 3-step sequenced laboratory activities to assess how it would affect their conceptual understanding of some analytical chemistry concepts in a conceptual laboratory. A quasi-experimental approach was adopted. Results from the study showed that majority of the trainees preferred engaging in virtual activities more than, and before physical activities. There were improved gains in conception with trainees’ engagement in sequenced experimentation with a Hake’s gain of 0.58.
