DEVELOPMENT AND VALIDATION OF STRATEGIC INTERVENTION MATERIALS (SIMs) IN MATHEMATICS FOR GRADE ONE

This study focused on the development and validation of strategic intervention materials (SIMs) in mathematics for grade one. This was conducted during the school year 2016-2017 using 252 grade one pupils and 140 mathematics teachers in Polillo District. Specifically, this study sought to identify the least learned competencies of grade one pupils in mathematics subject, develop SIMs based on the least learned competencies, and validate the SIMs through mathematics teachers. Least learned competencies were identified by means of administering a researcher-made test among selected grade one pupils and through ranking of the mean percentage scores of the competencies included. Five (5) SIMs were then developed by the researcher. The descriptive method of research was utilized in this study. A validating instrument was used to gather data regarding the validity and acceptability of the SIMs. On the validity of the components of the SIMs, results revealed that these were all “very evident”, which implies that the SIMs followed the standards/criteria for developing the guide card, activity card, assessment card, enrichment card, and reference card. On the acceptability of the SIMs, the respondents agreed that all the SIMs were “very much” acceptable in terms of content, organization and presentation, language used, and usefulness. This means the SIMs developed were highly satisfactory in terms of other things to be considered in SIM-making. Based on the findings, the SIMs developed in this study are well-formulated, valid, and ready for utilization by intended users. It is recommended that school administrators should motivate teachers to create their own SIMs and mathematics teachers, especially grade one teachers, should utilize the developed SIMs. Future researchers should also conduct a similar study in other grade level or a follow up study regarding the effectiveness of the SIMs developed by the present researcher.
