A Study of Scientific Conceptual Understanding on Solution of the 10th Grade Students by Using Learning Activities: Predict-Observe-Explain (POE)

Abstract

The objectives of the research were 1) to compare the learning achievement of the chemistry subject on solution and 2) to study scientific conceptual understanding on solution of the 10^th grade students by using learning activities: Predict-Observe-Explain (POE). The samples used in the research were 36 students studying in the 10^th grade in Room 4/3, Science and Mathematics Program, Narinukun school, Ubon Ratchathani Province, in the second semester of 2022 academic year. They were randomized by cluster random sampling. The research instruments were 1) 16 lesson plans in the chemistry subject on solution for the 10^th grade students and 2) an achievement test in the chemistry subject on solution for the 10^th grade students. The statistics used were percentage, mean, standard deviation, and t-test.

          The research findings were as follows.

1.  The learning achievement of the 10^th grade students in the chemistry subject on solution after learning by using learning activities: Predict-Observe-Explain (POE) after learning was higher than that before learning with the statistical significance at the level of .05.
2. The amount of the students in the scientific conceptual understanding groups consisting of a No Response group (NR), a Misconceptual Understanding group (MU), an Alternative Conceptual Understanding group, and a Sound or Good Conceptual Understanding group (SU) before learning were 12, 18, 5, and 1 student respectively, and the amount of the students in each group after learning were 0, 0, 15, and 21 students respectively. The amount of the students better understood the concepts during learning with the totally average 18.40%.
