A STUDY OF GRADE-11 STUDENTS’ PHYSICS LEARNING ACHIEVEMENT AND ATTITUDES IN LEARNING WAVES USING A 7-STEP LEARNING CYCLE WITH A SERIES OF EXPERIMENTS

Abstract

The objectives of this research were: 1) to develop a learning management plan of physics subjects on the topic of waves using a 7-step learning cycle in conjunction with a series of experiments with the efficiency criteria of 70/70; 2) to study the students’ achievements and the passing criteria after learning on the topic of waves using the 7-step learning cycle with the use of a series of experiments; and 3) to study the students’ attitudes towards studying physics using the 7-step learning with the use of a series of experiments. The samples were 38 grade-11 students, semester1, academic year of 2020, Khamsaen Witthayasan School under the supervision of the Office of the Secondary Educational Service Area 19, obtained through the cluster sampling. The instruments included: 1) a 7-step learning cycle lesson plan, a series of experiments with the efficiency criteria of 70/70, 2) two 4-choice and 30-item tests for measuring the students’ learning achievements on the topic of waves in physics subject with the difficulty of 0.35-0.75, the discrimination of 0.30 – 0.50, and the total reliability of 0.80-1.00; and 3) a 10-item with 5-rating-scale attitude test in learning physics subjects on the topic of waves using a 7-step learning cycle in conjunction with a series of experiments.

           The results showed that

1. The 2 learning management plans on the topic of waves in physics subject through the 7-step learning cycle together with the use of a series of experiments meet the required efficiency criteria of 70/70.
2. 2. The students’ learning achievement after learning through the 7-step learning cycle in conjunction with a series of experiments was significantly higher than the set criterion of 70 at the level of .05.
3. 3. The students’ attitudes towards physics learning after participating in the learning management using the 7-step learning cycle with the series of experiments were rated at the highest score of 5.00 in average.
