The Development of Special Needs Students Receptive Skills and Expressive Language Learning Management Special Education Centre Rajabhat Maha Sarakham University

Abstract

The purposes of the research were 1. to develop an instructional model for enhancing receptive and expressive language skills to achieve the efficiency criterion of 70/70 (E1/E2) 2. to compare students’ learning achievement before and after the intervention and 3. to examine students’ satisfaction with the developed instructional process. This study employed a quantitative experimental research design. The research instruments consisted of (1) lesson plans (2) a receptive and expressive language skills test with an index of item–objective congruence (IOC) of 0.58 and item discrimination indices ranging from 0.25 to 0.75 and (3) a satisfaction questionnaire with IOC values ranging from 0.80 to 1.00 and a reliability coefficient of 0.95. The sample comprised 14 students with special needs from the Special Education Center Rajabhat Maha Sarakham University, selected through purposive sampling. The collected data were analyzed using descriptive statistics, including percentage, mean and standard deviation, as well as a dependent-sample t-test. The research findings revealed that 1) the learning management model for developing receptive and expressive language skills achieved an efficiency of 70.15/70.30, which met the specified criteria 2) the sample receptive and expressive language skill achievement after the intervention was significantly higher than before at the 0.05 level and 3) the students’ overall satisfaction with the learning model was at a high level (x̅= 4.3, S.D. = 0.54)
