การพัฒนาระบบการช่วยเหลือทางคณิตศาสตร์สำหรับนักเรียนที่มีภาวะเสี่ยงต่อการเกิดความยุ่งยากทางคณิตศาสตร์ (Developing Mathematics Intervention System for Students at Risk in Mathematics Difficulties)

Abstract

The purpose of this research was to develop mathematics intervention system for students at risk in mathematics difficulties. Three phases of the research were conducted. The first phase was the development of the mathematics intervention system. The second phase was the development of the mechanism for mathematics intervention system. The final phase was the confirmation of the effectiveness of the mathematics intervention system. The research results revealed that: 1) Mathematics intervention system comprised of 3 elements :(1) identification (2) mathematics intervention and progress monitoring and (3) learning assessment. 2) The mechanism for mathematics intervention system’s instruments included (1) screening test for students at risk in mathematics difficulties (2) lesson plans that used in the system which included mathematics lesson plans for inclusive classroom and remedial mathematics lesson plans (3) a set of test for monitoring a progress in mathematics (4) mathematics achievement test (5) mathematics self-confidence scale. 3) The effectiveness of the mathematics intervention system was (1) the students in the experimental groups achieved a significantly higher in posttest scores than pre-test scores in mathematics achievement, mathematics self-confidence and learning retention at 0.05 level, (2) the students in the experimental groups achieved a significantly different scores from the students in the controlled group in mathematics achievement, mathematics self-confidence and learning retention at 0.05 level and the students in the experimental group achieved higher scores in all categories than the students in the controlled group
