The Effects of the Model-based Learning Instruction in the Topic of Pure Substance on Learning Achievement and Scientific Modeling Ability of Grade 7 Students at Nakorn Khonkaen School in Khonkaen Province

Abstract

The purposes of this research were to 1) compare the learning achievement of grade 7 students after learning through the model-based learning instruction with those of students who learned through the inquiry-based learning instruction, 2) compare the scientific modeling abilities of grade 7 students who learned through the model-based learning and those of the students who learned through the inquiry-based learning instruction, and 3) compare the scientific modeling abilities of students before and after learning through the model-based learning instruction. The research sample consisted of 70 grade 7 students from two classrooms of Nakorn Khonkaen School in Khonkaen Province who studied in the academic year 2023. The research instruments were 1) 5 lesson plans based on the model-based learning instruction and the inquiry-based learning instruction in the topic of pure substance for 20 hours, 2) a learning achievement test in the topic of pure substance, and 3) a scientific modeling ability test. The statistics used for data analysis were mean, standard deviation, and t-test for dependent samples. The research findings showed that 1) the learning achievement of students after learning through the model-based learning instruction was higher than those of the students who learned through the inquiry-based learning instruction at the .05 level of statistical significance, 2) the scientific modeling abilities of the students who learned through the model-based learning instruction was higher than those of the students who learned through the inquiry-based learning instruction at the .05 level of statistical significance, and 3) the scientific modeling abilities of the students who learned through the model-based learning instruction was higher than their pre-learning counterpart ability at the .05 level of statistical significance.
