Factors Affecting Learning Achievement of Science Subject of Matthayomsuksa 3 Students in Uthaiwitthayakhom School

Abstract

The objectives of this study were: 1) to investigate the factors influencing the learning achievements in science among Matthayomsuksa 3 students; and 2) to develop predictive equations for forecasting science learning achievements among Matthayomsuksa 3 students. The study involved a sample of 7 classrooms, comprising 208 Matthayomsuksa 3 students at Uthaiwitthayakhom School during the academic year 2022. The research tool utilized was a questionnaire comprising 53 items, demonstrating content validity with an Index of Congruence (IOC) ranging from 0.67 to 1.00, and a reliability of 0.799. Data analysis was conducted employing statistical methods including frequency, percentage, mean, standard deviation, and multiple regression using the Enter method. The findings are summarized as follows:
    1. The factors influencing the learning achievements in science among Matthayomsuksa 3 students comprised five elements: Achievement Motivation (X1), Scientific Attitudes (X2), Classroom Environment (X3), Existing Knowledge (X4), and Teacher Teaching Quality and Learning Achievement (X5). All factors exhibited high average scores. In aggregate, the overall average was at a high level ( = 3.93, S.D. = 1.14).
     2. All five factors collectively accounted for 68.40 percent of the variance in learning achievements in science subjects among Matthayomsuksa 3 students. Each factor exhibited a statistically significant impact on the learning achievements in science subjects among Matthayomsuksa 3 students, at the 0.01 significance level. In order of descending influence, they were as follows: Scientific Attitudes (X2), Achievement Motivation (X1), Existing Knowledge (X4), Teacher Teaching Quality and Learning Achievement (X5), and Classroom Environment (X3). The predictive equation can be expressed in terms of standard scores as follows:
Zy  = .306ZX1* + .321ZX2* + .212ZX3* - .318ZX4* + .258ZX5*
