Development of a Learning Object Lesson via the Internet with the Use of Inquiry Learning Approach in the Science Course on the Topic of Systems in Human Body for Mathayom Suksa II Students in Schools under the Secondary Education Service Area Office 35

Abstract

                The purposes of this research were to (1) develop a learning object lesson via the Internet with the use of inquiry learning approach in the Science Course on the topic of Systems in Human Body for Mathayom Suksa II students in schools under the Secondary Education Service Area Office 35 based on the set efficiency criterion; (2) study the learning progress of the students learning from the lesson; and (3) study the students’ satisfaction with the lesson. The research sample consisted of 34 Mathayom Suksa II students of Suanboonyopatham School in Lamphun province, obtained by multi-stage sampling. The employed research instruments comprised (1) a learning object lesson via the Internet with the use of inquiry learning approach in the Science Course on the topic of Systems in Human Body; (2) two parallel forms of an achievement test for pre-testing and post-testing; and (3) a questionnaire on student’s satisfaction with the lesson. Statistics used for data analysis were the E₁/E₂ efficiency index, t-test, mean, and standard deviation.  Research findings showed that (1) the developed learning object lesson via the Internet with the use of inquiry learning approach in the Science Course on the topic of Systems in Human Body was efficient at 80.23/79.20, 81.30/80.40, and 80.89/80.20, thus meeting the set 80/80 efficiency criterion; (2) students learning from the learning object lesson via the Internet with the use of inquiry learning approach in the Science Course on the topic of Systems in Human Body achieved significant learning progress at the .05 level; and (3) the students were satisfied with the learning object lesson via the Internet with the use of inquiry learning approach in the Science Course on the topic of Systems in Human Body at the high level.
