การนำเสนอรูปแบบการเรียนการสอนบนเว็บ วิชาวิทยาศาสตร์ ที่ใช้หลักการเรียนรู้แบบค้นพบด้วยการทดลอง สำหรับนักศึกษาสถาบันราชภัฏ / วาทินี สรรพวัฒน์ = A proposed web-based instructional model in science subject using experimental discovery learning approach for students in Rajabhat Institutes / Wathini Sapphawat
The purposes of this research were to study the opinions of the panel experts about the web -based instructional model design ed by using discovery learning approach , the achievement of the students that studied a chemistry course chemistry laboratory 2 from the web -based instructional model using discovery learning ap pro ach 1 and to present a proposed w eb-based instructional model using discovery learning ap pro ach for the students in Rajabhat Institutes. The sam ples of this research w ere gathered from 1) 47 experts involved in three different aspects: the w eb-based instructional model, the discovery learning, and teaching; and chemistry teaching 2) 20 second year bachelor degree students studying at Rajabhat Institutes Phranakhon Si Ayutthaya. The instruments used to collect data were questionnaires, w eb-based instruction evaluation 1 forms and test forms. The research study revealed the followings: 1.The experts ag reed that a w eb-based instructional model using the discovery learning approach consisted of three steps: introduction, teaching presentation, generalization and application. The students had to answer the questions of the first two step s and after the experiment by using the webboard or e-mail. The summaries of the experiment should be sent by using the webboard, the chatroom or e-mail. The discussion among the groups of 4-5 students should done by chatting. The graphic animation such as Flash should be used to show the devices and chemical substances. The result of the experiment should be recorded on php, web database or webboard which the students can watch the pictures on the digital video or PowerPoint on the web. The students should answer the pre-test and the post-test on e-mail. 2. The students who studied a chemistry course from the web-based instructional model which was constructed by using the discovery learning ap pro ach an d followed the step s and advice of the experts show ed significantly higher learning gains at the level of 0.05.
