Critical thinking is a purposeful and clear process used in mental activities such as problem solving, decision making, persuading, analyzing assumptions and conducting scientific research. The ability of thinking critically is effected by the competence of knowledge acquired by the students. Based on midterm exam, the result showed that 87,5% of students do not meet the minimum exhaustiveness criteria (KKM). One way that can be condusted to overcome it is applying inquiry learning model.the purpose of this research is to find out the effect of inquiry learning model towards studens’ critical thinking skills. The research is Quasi experiment research by using Randomized Control-Group Research Posttest Only Design. The population is VIII class student in SMPN 11 Padang. The sample is VIII.B students as an experiment class and VIII.C students as a control class, that are selected by purposive sampling technique. The instrument used is final test in form of essays to see the effect of inquiry laerning model of critical thinking ability of students. The hypothesis in this research is examinated by t-test, because the data is distributed normally and it has homogenen variation. Based on the research, the result showed that critical thinkingability t arithmetic > t table (4,23 > 1,67). Therefore, the hypothesis is accepted it can be concluded than applying inquiry learning model can give positive effecttowards students competence of critical thinking ability about excretion system in VIII class SMPN 11 Padang.

Penelitian ini bertujuan mendeskripsikan keefektifan pembelajaran matematika berbasis masalah, problem posing, dan pendekatan konvensional serta perbandingan keefektifannya ditinjau dari kemampuan berpikir logis dan kritis. Jenis penelitian adalah quasi experiment dengan pretest-posttest with nonequivalent group design. Populasi penelitian adalah 240 siswa kelas VIII SMP Negeri 2 Ciamis. Tiga kelas diambil secara acak untuk sampel penelitian, kemudian ditentukan lagi secara acak kelas eksperimen pertama, kelas eksperimen kedua, dan kelas kontrol. Instrumen yang digunakan adalah tes kemampuan berpikir logis dan tes kemampuan berpikir kritis yang terdiri atas soal pretest dan posttest. Teknik analisis data meliputi t-one sample test untuk menguji keefektifan masing-masing pendekatan pembelajaran dan MANOVA untuk menguji perbedaannya yang dilanjutkan dengan uji  univariat. Semua uji menggunakan taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa: (1) pembelajaran berbasis masalah dan problem posing keduanya efektif ditinjau dari kemampuan berpikir kritis tetapi tidak efektif ditinjau dari kemampuan berpikir logis sedangkan pembelajaran konvensional tidak efektif ditinjau dari kemampuan berpikir logis maupun kemampuan berpikir kritis; (2) ditinjau dari kemampuan berpikir logis, tidak ada perbedaan yang signifikan antara pembelajaran berbasis masalah dan problem posing tetapi keduanya lebih unggul dibandingkan pembelajaran konvensional sedangkan jika ditinjau dari kemampuan berpikir kritis, pembelajaran berbasis masalah lebih unggul dibandingkan pembelajaran problem posing dan pembelajaran konvensional serta pembelajaran problem posing lebih unggul dibandingkan pembelajaran konvensional. Kata Kunci: pembelajaran berbasis masalah, problem posing, kemampuan berpikir logis, kemampuan berpikir kritis   THE EFFECTIVENESS OF PROBLEM-BASED LEARNING AND PROBLEM POSING IN TERM OF THE LOGICAL AND CRITICAL THINKING ABILITY Abstract This study aims to describe the effectiveness of mathematics instruction through the problem-based learning, problem posing, and conventional learning approach with their effectiveness compa-ration in terms of logical and critical thinking ability. This research was a quasi-experimental study using the pretest-posttest with nonequivalent group design. The population of this research was all 240 students of grade VIII SMPN 2 Ciamis. Three classes were randomly established as the research sample, later established randomly the first experimental class, second experimental class, and control class. The instruments used in the research were a logical thinking ability test and critical thinking ability test, consisting of a pretest and posttest. The data analysis techniques consisted of the t-one sample test to investigate the effectiveness of each learning approaches and MANOVA to investigate their difference and continue by univariate test. All of tests use the 5% of significance level. The results of the research show that: (1) both of the problem-based learning and problem posing are effective in terms of critical thinking but they are not effective in terms of logical thinking and the conventional approach is not effective in terms of both the logical and critical thinking; (2) in terms of logical thinking, there are not signifficant difference between problem-based learning and problem posing approaches but they are better than conventional approach and in terms of critical thinking, problem-based learning is better than both of problem posing and conventional approaches and problem posing is better than the conventional approach.

The low understanding of the students on the biology materials in the learning process of science causes the students' repetition value to be low. With by this background the aim of this research was to know the cognitive ability and critical thinking ability of students who in their learning process apply Problem Based Learning (PBL) learning model by using exelearning. The sample in this research is 40 students of class VIII in MTs Negeri 2 Cirebon. The sampling technique used in determining the sample was Purposive random sampling. This research uses experimental method with one class given treatment and other class not given treatment that acts as control. From the result of data analysis, it can be concluded that the cognitive ability and critical thinking ability of students using PBL (Problem Based Learning) model with exelearning assistance was superior compared to using the lecture model on the concept of human excretion system. The improvement of students' cognitive ability in the experimental class seen from the N-Gain value reached 0.73 (high) compared to the control class which only reached 0.13 (low). As for the increase gain N-Gain value of 0.71 (height) and control class reaches the value of 0.25 (low)Keywords: Problem Based Learning Model (PBL);� Exelearning; Cognitive Ability; Critical Thinking Skill

Thinking Ability

Mathematical Critical thinking is one of  mathematical abilities that must be obtained by students. Critical thinking is one of the high order thinking processes that can make concepts in student knowledge.  Students with critical thinking in mathematics learning mostly do rational activities such as interpreting information based on a particular theoretical framework, linking theory with practice, making claims and justifying it, utilizing data in support of argumentation, making relations or relationships between various ideas, asking questions, evaluating knowledge, predict, describe something, analyze, synthesize, and categorize. This study aims to analyze the effect of the Concept-Based Learning Model on the critical thingking mathematical abilities.The purpose of this research is to analyze the effect of Concept-Based Learning Model toward mathematics critical thinking ability. The method used in this research is quasi experiment by Randomize Control Group Post Test Only Design with cluster random sampling technique. Indicators of mathematics critical thinking skills measured in this study include providing simple explanations, building basic skills, concluding, making more explanations, and deciding an action. The results showed that the mathematics critical thinking ability of students in the experimental class for the five indicators that being analyze was higher than the ability of students in the control class. A fairly high difference in the indicator showed in give a simple explanation and concluding. and it means that the application of Concept-Based Learning Model significantly influences the  abilities  of students' mathematics critical thinking.
