Brain-based strategic intervention material (BSIM) for integers

Abstract

This design research aimed to develop a Brain-Based Strategic Intervention Material (BSIM) for Integers as a tool for remediation, particularly in Numbers and Number Sense. The respondents of this study were one section of 36 grade seven learners of Lezo Integrated School, four grade seven learners for the interview, and four experts for the evaluation of the acceptability of the BSIM. The data gathering instruments were the pilot testing tool, evaluation rating sheets for the quality assurance of print learning materials, and interview guide. Data analysis techniques employed were frequency count, percentage, mean, and thematic analysis. From a survey that was conducted by the Schools Division of Aklan on the identification of the least learned competencies in grade seven mathematics, from a total of fifteen learning competencies, six of those were considered least learned competency. From this, the topmost least learned competency which is to perform fundamental operations on integers was considered in the study. Reasons for such difficulty included the confusion of learners with the signs and grouping symbols. In response to this concern, a BSIM integrating the distinct features of Tom Lavella's Brain-based Learning and Teaching Strategies composed of title card, guide card, activity card, assessment card, enrichment card, reference card and answer card was developed. As to the overall acceptability of the strategic intervention material in terms of its content, language and layout and format, the experts agreed that the BSIM is highly acceptable. The BSIM met and complied with the standards set by DepEd on Locally Developed Material. The learners and teachers find the BSIM as unique and innovative, simple and direct, and effective for remediation making it a great remediating tool for learners experiencing difficulties in performing operation of integers. It is recommended that BSIM be used in Grade 7 mathematics as an alternative material for remediation.
