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.

Addressing common deficiencies of mathematics skills among chemistry student teachers
Abstract
The need for the inclusion of a special mathematics course for students studying chemistry at the tertiary level of education has been justified by several reasons ranging from the mathematical processes involved in understanding chemistry, students’ inability to handle simple mathematical manipulations required in chemistry, and the lack of transfer of mathematical skills learned in mathematics class to chemistry. At a South African university, we faced the challenge of addressing common mathematical skill deficiencies among our chemistry student teachers (N = 82), who appeared unable to cope with basic mathematical skills required in understanding certain chemistry topics. To address this problem, students’ mathematical deficiency skills (DMS) were assessed using tests on various areas of mathematics relevant to some chemistry topics. The data was collected in two stages. DMS were first identified using a Semi-open Diagnostic Test, and then students who had the worst DMS were interviewed. The findings revealed that a lack of skills in these mathematics topics (e.g., algebra, curve sketching, simple differentiation and integration) causes students to struggle in producing the breadth of knowledge required to understand chemistry concepts such as kinetics, rates, and reaction mechanisms, as students lacked: (i) the ability to resolve the relational complexity among major mathematics concepts in chemistry problems, and (ii) the ability to process information and representation skill, number and pattern concept skill, and visual-spatial skill.
