THE DEVELOPMENT OF CRITICAL THINKING ABILITY THROUGH ARCS MODEL LEARNING ACTIVITIES ON THE SEQUENCE AND SERIES OF GRADE 12 STUDENTS

Abstract

This research was aimed to: 1) study the guidelines for ARCS Model learning activities on the sequence and series, and 2) to develop the critical thinking ability through ARCS Model learning activities on the sequence and series of grade 12 students. The research followed action research consisting of planning, action, observation, and reflection. It operates as a continuous operating cycle of 4cycles. The participants consisted of 12 students in grade 12. There were four research tools which are lesson plan based on ARCS Model learning activities on sequence and series, reflection form, activity sheet, and critical thinking ability test. The results showed that: 1) Guidelines for learning activities should focus on: 1.1) asking questions and giving examples of situations; 1.2) linking the definition/theorem of sequences and series to real situations; 1.3) arguing with appropriate reasons; and 1.4) finding a way to find a variety of answers, 2) the development of critical thinking ability of students in grade 12 were: 2.1) during the using of the ARCS Model learning activities on the sequence and series, students’ critical thinking abilities were enhanced in overall, 2.2) after learning through ARCS Model learning activities on the sequence and series, most students’ critical thinking abilities (89.85%) were at a good level.
