Achievement of Using Multimedia Activities Package on Basic Chemical Thermodynamics with "Gifted" Science Students

This research aimed to develop students’ learning process and teachers’ instruction, to construct a multimedia activity package on basic chemical thermodynamics and to study the achievement of using the multimedia activity package with “Gifted” students who were keen on science. The sample group consisted of 40 “Gifted” students from Samakkhi Witthayakhom School, Chiang Rai. The multimedia activity package was implemented for 12 hours. After that, the final exam was conducted to examine the academic performance of the students. The test was comprised of 30 items of four-multiple-choices. The result was analyzed in terms of mean, standard deviation, and t-test values. The results have shown that the efficient criterion were 87.45/86.04 after using the multimedia activity package on basic chemical thermodynamics. It was higher than the standard efficient criterion 80/80. Therefore, the learning achievement of the students in the post-test was better than the one in pre-test with statistical significance at 0.05. Professional Learning Community (PLC) was implemented in the instructional process. It was the process that allowed students to learn through self-directed method and reflective learning method. The results illustrated that the students were satisfied with their performance with the mean of 4.56 or it was accounted for 91.20 percent.
