This research is conducted by the low mathematics critical thinking ability of students in junior high schools, especially in  VII grade .Students of VII grade commonly are transitioning from elementary school to junior high school could be a reason how low students of VII grade on mathematic critical thingking ability. The low ability mathematics critical thingking one of caused by mathematics anxiety. This study aims to find a relationship between math anxiety and mathematics critical thinking ability of VII grade at SMPN 5 Serang City. The method of this research is quantitative descriptive by making 110 students from VII grade as a sample. The data were collected using questionnaire and test. The result of this study indicate that 1) the ammount of correlation between math anxiety with critical thingking ability is -0,5991> rs table 0,1695, which means there is a significant and negative relationship between anxiety and critical thingking ability 2) the average of students’s mathematics critical thingking ability is different where score between students with low anxiety have a better score than student with mid anxiety and low anxiety,and students with mid anxiety have a better score than students with high anxiety, and students with mid anxiety have a better score than students with high anxiety.

This study aims to inventory the type of necton, knowing the structure of the necton community and measuring the critical thinking skills of students of class VII.1 SMPN 1 Ujan Mas Kepahiang. The results showed that the necton obtained from the Taman Pintar pond amounted to 7 species and Pipi Putih Pond totaling 4 species. The necton species in the Taman Pintar pond  with the highest KP, KS, and FK values are tin head fish with KP, KR, and FK values respectively  0.102 idv / m2, 75.71% and 83%. While on the Pipi Putih Pond is local catfish species with the value of KP, KR, FK of 0.01 idv / m2, 39.29% and 25%. Then dominance index (H ') in the Taman Pintar pond is 0.61 and C' Pipi Putih pond  = 0.76. While the index of diversity of necton species in both ponds also belonged to very low category with H’ value of Taman Pintar Pond = 0.28 and H' of Pipi Putih pond  = 0.17. The result of Percentage Of Agreement test showed that  environment-based learning tools developed are included in the category highly feasible to be tested. Students’ critical thinking ability on the perpormance aspect shows 33 ,3 % percentage including critically critical criteria and 66,7 % including critical criteria. While Students’ critical thinking ability on the cognitive aspect shows four criteria, that are very critical as 26 %, crittical criteria 40 %, criteria critical enough 27 % and  criteria less 7 %

This research is aimed to develop learning device of Guided Discovery model with PhET simulation to trill students critical thinking skill. This research uses 4D development model and tested on 15 students of class XII IPA with test design using one group pretest-posttest design. Learning tools developed include: (a) syllabus (b) RPP, (c) student books, (d) LKS, and (e) tests students' critical thinking skills. Research data obtained through validation method, observation, test, and questionnaire. The results are analyzed descriptively quantitative and qualitative. The students' critical thinking ability is analyzed by n-gain. The result of the research shows that (a) learning device developed categorized is very valid, (b) learning activity is done very well, (c) critical thinking ability of students have moderate improvement, and (d) students respond very positively to learning which has been implemented. Based on the results of the analysis and discussion, it was concluded that the learning device of Guided Discovery with PhET simulation model developed is feasible to be used for trained critical thinking skills of high school students.

The aim of this research is to analyze the effectiveness of students worksheet to improve of critical thinking ability of fourth grade student’s of SD N 5 Parakan Kauman based on STEM (Science, Technology, Engineering, Mathematics) and local wisdom. This research adopt the procedure of research and development that oriented in 4D model (Define, Design, Developed, and Disseminate). The research design used was one groups pretest-posttest design with the member of subject were 24 students. The research instrument used observation sheet, interview sheet, validity test, written test (pretest and posttest), and also questionnaire. The result of the research showed that students worksheet included in the effective enough category, which based on the calculation of N-Gain score was 62.7809 or 62.8 %, with a minimum score is 57.14 % and a maximum score 66.67 %. These scores showed the improvement of student thinking in solving problem aspect, with good and very good categories. The result of the teacher respondent is 67, it is in interesting category and the student respondent got 84 in average score, it is in very interesting category. It can be concluded that the implementation of student worksheet in STEM basic and local wisdom can be implemented in teaching learning activities, it also improve the ability of students’ critical thinking.

The objective of this reaserch was to produce physics learning materials with learning cycles (5E) model which focuced on the validity, practically, and effectiveness to facilitate student’s critical thinking ability in calor matter. The learning tools development using 4D (define, design, develop, and disseminate)  development model and have been tested on second semester students of physics education, The Science Teacher Training Institute of Mataram. This trial development of research using one group Pre-test Post-test Design. Data collection methods used were validation paper questionnaires, tests and observation, whereas data analysis techniques using qualitative and quantitative descriptive method. Based on the assessment the validator has a valid criteria, showing several findings, namely, 1) the devices at the implementation stage, devices are developed have  practical criteria, which are measured by the implementation of the criteria learning “well done” and the response of students are “strong” 2) the effective developed  to train critical thinking ability, where there is an increase in students, critical thinking ability from the initial test on 62 to 90 in the final test. The result of the study generally show that physics learning devices use a valid, practical, and effective, and 5E learning cycle model to train students critical thingking ability.

This study aims to develop problem-based learning tools to improve critical thinking skills that are valid, efficient, and effective for use in learning on harmonious vibration material. This research is a type of research and development (R&D) with a 4D model. At the define stage, is the initial stage for defining the problem. The design stage, designing learning device products in the form of syllabus, lesson plans, student worksheet, critical thinking skills test instruments, and learning videos. The develop stage is the development of the device from the results of the validity of the learning tools obtained from the validation results of 6 validators consisting of 3 expert validators and 3 on validators. The practicality or efficiency of the learning device is obtained from the responses of students and the learning implementation sheet. Increased critical thinking ability of students to analyze by determining the standard acquisition of the results before and after learning. The results of the validation show that the learning device components are in the very valid category for the syllabus and valid enough for lesson plans, student worksheet, critical instrument test skills, and video learning which means that they are good enough to be used in learning Reliability of the syllabus, lesson plans, student worksheet, critical thinking ability test instruments, and learning videos above 75% show all components that are in the reliable category. The results of student responses, as well as the implementation of learning are in the very practical category. Student learning outcomes have increased with a acquisition value of 0.66 which is in the medium category. Based on these results, it can change valid, efficient and effective problem-based learning tools used to improve students' thinking skills. The last stage is to disseminate the dissemination stage of the device where at this stage it is done by making journals to send
