การพัฒนาทักษะกระบวนการทางวิทยาศาสตร์และความสามารถในการคิดอย่างมีวิจารณญาณ ของนักเรียนชั้นมัธยมศึกษาปีที่ 3 โดยใช้การจัดการเรียนรู้แบบวัฏจักรการเรียนรู้ 7 ขั้น (7E) ร่วมกับการใช้ผังกราฟิก

Abstract

The objectives of this research were to 1) develop science process skills of Mathayomsuksa 3 students using the learning management based on the 7E learning cycle with graphic organizers, resulting in an average score of at least 70 percent of the total score, and a minimum of 70 percent of students passing, and 2) foster the critical thinking ability of Mathayomsuksa 3 students using the developed learning management with an average score not less than 70 percent of the total score, and at least 70 percent of students passing. The target group consisted of 15 Mathayomsuksa 3 students. The research design was an action research methodology within a 3 cycle process. The research operational tool included six 18-hour lesson plans based on the 7E learning cycle with graphic organizers. The research reflective tools consisted of 1) instruction records, 2) an instruction observation form, and 3) an interview form and end-of-spiral quizzes. The research assessment tools included 1) a 12-item test on science process skills, and 2) a 35-item test on critical thinking ability. Statistics for data analysis consisted of mean, standard deviation, and percentage. The qualitative data were analyzed through content analysis.

The results revealed that:

1. The students demonstrated science process skills at a score of 17.93 with a standard deviation of 2.69, equivalent to 74.71 percent of the total score. A total of 11 students, or 73.33 percent, achieved scores that were higher than the defined criteria.

2. The students exhibited a critical thinking ability score of 25.93 with a standard deviation of 2.91, equivalent to 74.09 percent of the total score. A total of 12 students, or 80.00 percent, achieved scores that were higher than the defined criteria.
