Critical thinking skills need to be developed in learning activities because these skills are needed by students especially in solving problems both in everyday life and for the future. Based on research that has been done, students' critical thinking skills can be developed by implementing the rally coach learning model in mathematics learning activities. Rally coach is a cooperative learning model. From the research results obtained using descriptive research methods with a qualitative approach, students' critical thinking skills have increased significantly which indicates that the implementation of the rally coach learning model was declared successful. This study has been done using CAR (Class Action Research) method with 4 cycles. As part of the research, to find out an increase in accordance with expected, researchers designed a test instrument that has been tested for validity and reliability using the content validity ratio (CVR) method and the Cronbach Alpha formula. The results that have been obtained show in detail that the rally coach learning model provides an excellent contribution to improving students' critical thinking skills.

Development Of Students

Problems that are often encountered in learning activities include students having difficulty expressing ideas and opinions related to lecture material, when their discussions are more fixated on explaining the reading sources they get either through books or through other electronic media without being able to develop and explain rationally, analysis, as well as critical of the source of the reading. In terms of lecturers as educators, in providing learning to students, on average, they still use conventional patterns, namely the lecture model where students only act as recipients of information from the lecturers. All of this will certainly lead to the development of students' critical thinking skills during lectures. The ability to think critically, of course cannot be obtained just like that without a process in education, and not everyone can easily get it. This study aims to determine how to improve students' thinking skills through a jigsaw learning model. The method used in this research is class action with two cycles. The results showed that there was an increase in students' critical thinking skills after using the jigsaw learning model in learning activities.Key words : Learning, Model of Jigsaw Learning, Critical Thinking Ability

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.

The demand of KKNI curriculum in the 21st century is about the equality of learning achievement covering attitudes and values, work ability, scientific mastery, authority and responsibility. For that, PGSD graduates of Sarjanawiyata Tamansiswa University (UST) Yogyakarta are expected to be able to design the learning activities, which is in line with the development of science, and technology, which is on the same time, are able to bring Indonesian cultural value into it. The graduates’ competence are presented in their abilities to develop elementary school learning activities based on the Science Environment Technology and Society (SETS) and integrate local wisdom into it. The purpose of this research is to describe the skills of critical thinking of PGSD students in developing SETS-based learning integrated with local wisdom and also along with the indicators that appear in each skill aspect. This is a type of quantitative descriptive research with non-test data collection techniques, observation, and documentation. While the main instruments are in the form of Student Worksheet (LKM), the observation sheet towards the indicators of critical thinking skills. Data analysis techniques is done by using descriptive statistics interpretation through several answering criteria: very good, good, fair, poor, and very poor which is then the results are presented in the form of tables. The results showed that the average critical thinking ability of PGSD UST students was 69.24% with can be categorized in good criteria. Indicator of every critical thinking skills aspect has appeared, even though some targets of achievements have not been optimally gained yet.

This research is to determine the effect of learning model and critical thinking skills toward mathematics learning achievement of class XI IPA students in senior high school in Gianyar by controlling students’ numeric aptitude. This research used treatment by level 2x2 design and analysis of covariance. The sample was 80 people using multistage random sampling. The results by controlling numeric aptitude are: students learning achievement taught using PAIKEM model is higher than those taught in conventional model. There is an interaction effect between learning model and critical thinking skills toward students’ mathematics achievement. Given high critical thinking skills, students taught using PAIKEM models displayed higher results compared to those in conventional learning who were best in a lower critical thinking skills. Finally, based on the results, it can be recommended to SMA Mathematics teachers to increase students’ Mathematics achievement by using PAIKEM model accurately and to see of students critical thinking skills.

Learning activities were carried out online or the Online Learning Model (OLM) in the era of the Covid-19 pandemic. Every student who participates in OLM is trained in critical thinking and regularly improves the solving of a mathematical problem. This research used qualitative research with a descriptive approach. Researchers were interested in identifying critical thinking standards of analysis at the Novice Performance Level with the Online Learning Model (OLM) in Geometry Lectures in solving geometric problems based on students' Critical thinking skills with analysis indicators. Subjects were taken based on the assignment score on the material. Subjects were grouped into 3 abilities, namely low ability (Re), medium ability (Se), and high ability (Ti). The number of subjects was three people who were taken from each group at each level. Data were collected using 2 mutually supporting instruments, namely the test instrument and the interview instrument. The validation used was expert validation and content validation. The results showed that online learning activities or the Online Learning Model (OLM) can be identified that subjects with low abilities fulfill all indicators in the analysis stage, while not meeting all indicators for moderate and high student abilities because the Novice performance level is in accordance with its understanding, namely the lowest level where the subject had not been able to solve the given problem at all.
