The Development of Learning Achievement through Learning Activity Packages on the Topic of Solutions in Chemistry II for Grade 10 Students

Abstract

This research aimed to: (1) study the efficiency of the learning activity package on Solutions in Chemistry II for Grade 10, Class 1 students, to meet the specified criterion of 80/80 (E1/E2); (2) compare the students’ learning achievement before and after the implementation of the learning activity package; and (3) study the students’ satisfaction towards the learning activities using this package.The sample group consisted of 28 students in Grade 10, Class 1, Science-Mathematics Program, Plong Witthayakom School, in the second semester of the academic year 2024, selected by purposive sampling.The research instruments included the learning activity package, inquiry-based lesson plans, pre-test and post-test achievement assessments, and a student satisfaction questionnaire towards the learning activities.Data were analyzed using descriptive statistics, namely percentage, mean, standard deviation, and efficiency index (E1/E2). The research results showed that: (1) The learning activity package had an efficiency of 80.52/85.48, which was higher than the specified criterion; (2) The post-learning achievement was significantly higher than the pre-learning achievement at the .01 level; and (3) The students’ satisfaction was at a high level (mean = 4.44).
