The Development of Learning Achievement and Basic Research Skills by Using Instructional Package on Research for Development of Learning Innovation (Code 1043407-62) for 3rd year Student Teachers of Phetchaburi Rajabhat University

Abstract

          This study aimed to investigate the development of learning achievement and basic research skills among pre-service teachers through the use of an instructional package for the course Research for Learning Innovation Development (Course Code 1043407-62). The objectives of the study were to: (1) compare pre-service teachers' learning achievement before and after learning through the instructional package, (2) determine the Effectiveness Index (E.I.) of the instructional package, and (3) assess the basic research skills of pre-service teachers after learning through the instructional package.

          The sample consisted of 27 third-year pre-service teachers majoring in Mathematics at Phetchaburi Rajabhat University, selected through purposive sampling. The research instruments included: (1) an instructional package for the course, comprising nine instructional units, (2) a learning achievement test for the course, and (3) a basic research skills assessment form. All research instruments were examined for content validity using the Index of Item–Objective Congruence (IOC), item difficulty, discrimination power, and reliability, and all met the established quality criteria. Data were analyzed using the mean (M), standard deviation (SD), the Effectiveness Index (E.I.), and a paired-samples t-test.

          The findings revealed that: 1) The pre-service teachers' posttest learning achievement was significantly higher than their pretest achievement at the .01 level of statistical significance. 2) The Effectiveness Index (E.I.) of the instructional package was 0.7929 (79.29%), indicating a high level of learning effectiveness and 3) The basic research skills of the pre-service teachers after learning through the instructional package were at an excellent level.
