Purpose – The purpose of this paper is to improve the critical thinking of biology students of STKIP Hamzanwadi Selong on an environment course through the implementation of Problem-Based Learning (PBL) and Group Investigation (GI) through Lesson Study. Design/methodology/approach – This study employed a descriptive qualitative method. The subjects of the study were 73 freshmen biology students academic year 2013/2014 who were divided into two classes. The Lesson Study was conducted in 16 cycles, comprising Plan, Do, and See stages. The instrument of the study used to measure the students’ critical thinking was an essay test which covered several criteria of critical thinking adapted from SOLO Taxonomy. Findings – The implementation of PBL and GI encouraged the students to think critically through planning, arguing, stating questions and problems, and analysing and providing solutions to the surrounding environmental problems. Originality/value – This study depicted Lesson Study activity on an environment course which focused on the students’ critical thinking activity through the integration of PBL and GI. The learning was conducted through Lesson Study and was based on the environment. The crucial value of the Lesson Study was the lecturers showed more attention to the students since they wanted to know the students’ learning style and what made them learn.

Pbl Model

This study aims to determine the effectiveness of the Problem Based Learning (PBL) model on the critical thinking skills of 7th-grade students of SMP Negeri 34 Bandarlampung (Public Senior High School 34 Bandarlampung). This quasi-experiment involved 2 groups of students, totaling 28 students for the Experimental class and 26 students for the Control class. Data collection was obtained by using an essay test instrument which was presented in the pretest and posttest. Based on the research results, it is known that the posttest results of the experimental class are 78.82, and the results of the control class are 74.07. The data were then analyzed by independent sample t-test and obtained tcount (2.213) greater than ttable (2.007). The effectiveness of the Problem Based Learning (PBL) model was tested with the effect size test, the results showed a number of 0.2 with a low category. So, it can be concluded that the Problem Based Learning (PBL) model has an effect on increasing students’ critical thinking skills but with low effectiveness.

Abstract: The study aims to understand the implementation of Problem-Based Learning and its impact on critical thinking skills for senior high school students. The study used the lesson study approach that was conducted in four cycles. Each learning activity consisted of identifying topic, presenting the report, and evaluating the Problem-Based Learning. The subject of the study was in a Senior High School in Malang, Indonesia. The level of critical thinking refers to Structure Observed Learning Outcome (SOLO) Taxonomy, consisting of Prestructural, Unistructural, Multistructural, Relational, and Extended Abstract thinking levels. The findings in the learning process show that the students’ critical thinking skills has increased. It is revealed by improving the ability to solve problems and making conclusions through critical thinking processes. The implementation of Problem-Based Learning also encourages students to think critically in the form of questioning, discussing problems and making solutions related to the employment issues, national income and economic growth in Indonesia.  Keywords: Problem-Based Learning, Critical Thinking Skills, Lesson Study APAKAH PROBLEM-BASED LEARNING DAPAT MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS? Abstrak: Penelitian ini bertujuan untuk mengetahui penerapan Problem-Based Learning dan pengaruhnya terhadap kemampuan berpikir kritis pada siswa sekolah menengah atas. Penelitian ini menggunakan pendekatan lesson study yang dilakukan melalui empat siklus. Setiap aktivitas pembelajaran terdiri dari mengindentifikasi permasalahan, mempresentasikan laporan kegiatan, dan mengevaluasi pelaksanaan Problem-Based Learning. Subject penelitian ini dilakukan pada sebuah Sekolah Menengah Atas di Malang, Indonesia. Tingkat kemampuan berpikir kritis siswa dalam penelitian ini mengacu pada taksonomi SOLO (Structure Observed Learning Outcome) yang meliputi prastruktural, Unistruktural, Multistruktural, Relasional, and Extended Abstract. Hasil penelitian ini menunjukkan bahwa selama proses pembelajaran, kemampuan siswa dalam berpikir kritis telah meningkat. Hal ini ditunjukkan dari peningkatan kemampuan menyelesaikan masalah dan membuat kesimpulan melalui proses berpikir kritis. Penerapan Problem-Based Learning juga mendorong siswa memiliki kemampuan berpikir kritis dalam berbagai aktivitas seperti mengajukan pertanyaan, mendiskusikan permasalahan, dan membuat solusi terkait permasalahan pengangguran, pendapatan nasional, pertumbuhan ekonomi di Indonesia. Kata Kunci: Problem-Based Learning, Kemampuan Berpikir Kritis, Lesson Study

Education functions to upgrading, forming, character and develop civilization nation. Having the ability to think and actions to effective and creative in the realm of abstract and concrete can be used as self development independently. Students need to armed with critical thinking skills, systematic, logical, creative, and cooperate effectively to obtain, choose, and manage an information. Mathematics learning is directed to develop critical thinking skills and discussed open and objective because mathematics having strong and structure clear and links between the concept of the one with another concept. By analyzing learning needs of mathematics, formulate and designed a learning programs, choose a strategies and evaliated them correctly to get good results. The ability critical thinking is very important in studying new matter and that known way, and learn to ask effectively and reach a conclusion consistent with the facts. Mathematic learning with problem based learning is the concept of better used activity of the student during learning. In accordance with statements from Westwood (2008: 31) stated that PBL: 1) propel oneself directly in learning, 2) prepared students to critical thinking and analytical, 3) give opportunity to students to identify, find and use numerous this approuch in should think, 4) is the learning is very closely related to the real world and motivate students, 5) involving activeness in integrating information and skills of various the discipline, and 6) knowledge and strategy by the possibility of will be maintained and tranferred to the learning situation other, improve the ability to communicate and the social skills needed to cooperation and teamwork. By chance the learning process as an alternative in solving mathematical problems with using the ability critical think an to cultivate the scientific attitude of student.
