The low ability to understand concepts is something that is still often found in mathematics learning, especially in secondary schools. One of the reasons is the lack of learning device  that encourage students to be active in learning. Therefore, it is necessary to develop contextual learning tools in an effort to improve students' the ability understand mathematical concepts (AUMC) students. The type of research is descriptive quantitative. The research instrument was in the form of a learning device validation sheet. The research subjects were learning device which included lesson plans, student activity sheets (SAS), and students' AUMC tests. The object of research is the level of validity of the learning device. The results showed that the lesson plan with an index V of 0.72 was categorized as valid. SAS with an index V of 0.78 is categorized as valid, The AUMC-1 test and the AUMC-2 test with an index of V 0.76 and 0.74 were included in the valid category. It can be concluded that the contextual approach in improving student AUMC from the aspects of format, language and content is valid.

The purpose of this study was to describe the results of the development of problem solving-based mathematics learning tools to train the creativity of students on estimating the amount and difference of two fractions in grade IV SD Khadijah. The development of learning tools in this study uses the Thiagarajan 4D model which is modified into 3D, namely the define stage, the design stage, the development stage. Learning tools developed include RPP, LKPD, and TKPD. The instruments used were the learning device validation sheet, the teacher and student activity observation sheet, the student's creativity test, and the learning outcome assessment. After the data were analyzed descriptively, the results of the study were as follows: the average value of the RPP was 3.79, the validity value of the LKPD was 3.50, and the results of the TKPD validation could be used with minor revisions. So that the learning device is said to be valid. The teacher's activities in implementing problem-solving learning have been good because all the learning steps in the lesson plan have been carried out. The activities of students while participating in learning at meeting 1 and meeting 2 have increased. With an increase in the activity of students it means that students are active in participating in problem solving-based mathematics learning. The students' creativity test was given two tests, namely before and after problem-solving based learning. The results of the creativity tests of students before and after problem solving based learning were 37.8% and 57.9%. Thus, the creativity of students has increased significantly after using problem-solving based learning tools.

This study aims to find out how the development of Batak Toba culture-based mathematics learning media with a contextual approach and to find out how effective the development of Batak Toba culture-based mathematics learning media with a contextual approach is. The development of mathematics learning media was prepared using the ADDIE model. The subject of this research is class VII E with a total of 32 students. The type of data used is qualitative data and quantitative data. The first stage is the analysis phase. This stage is done to analyze the needs of research such as researchers conducting observations, interviews, and pretests. The next stage is the design of a mathematics learning media design in the form of Student Activity Sheets (LAS) based on the Toba Batak culture. The third stage is development, at this stage the learning media product is validated by the material expert and media expert validator to obtain the feasibility of the product that has been designed based on the results of the validation and the validator's suggestions and comments. The fourth stage is implementation, at this stage after the mathematics learning media product is validated then the product is tested. The last stage is evaluation, at this stage after the product is tested the final results of the field test in the form of a pretest and posttest are then analyzed and scores are obtained as a result of student learning. Based on the analysis of research data, the following results were obtained: (1) Student Activity Sheet (LAS) based on Toba Batak culture can be used for mathematics learning on the subject of rectangles and triangles in terms of the value given by the material expert and media validator 88% with a very valid and appropriate category to be used to improve student learning outcomes; (2) Increasing student learning outcomes by 56.25% this can be seen from the pretest students who completed as many as 11 people (34.37%) while students who did not complete as many as 21 people (65.63%). From the posttest students who completed as many as 29 people (90.62%) while students who did not complete as many as 3 people (9.38%); (3) The teacher's activities at the 1st and 2nd meetings achieved results (85.23%) and the student activities at the 1st and 2nd meetings achieved results (88.66%). So it can be concluded that student learning outcomes at posttest are higher than at pretest. Thus that mathematics learning media in the form of Student Activity Sheets (LAS) based on the Toba Batak culture are effective for use in improving student learning outcomes.

Students' critical thinking skills in Indonesia are still categorized as low, so it is necessary to facilitate learning tools that support critical thinking activities. One of the learning tools is the inquiry-based Student Activity Sheet (LKS) which can train students' critical thinking skills. The purpose of this study was to develop inquiry-based worksheets on animal tissue learning material for class XI SMA Negeri 3 Mojokerto. The model used in this research is the 4-D model, namely define, design, develop and disseminate. The research subjects were 12 students of class XI MIPA 1 as many as 12 students of SMA Negeri 3 Mojokerto. The results of the percentage agreement validation of the LKS were 96% categorized as reliable. The effectiveness of the student worksheet is based on a gain score of 0.89 with high criteria so that the device is said to be effective. Student responses to the developed worksheets obtained results of 99.08% with a very good response. Thus, inquiry-based student worksheets on animal tissue learning material can train students' critical thinking skills.Keywords: Student activity sheet, inquiry model, critical thinking skills, animal tissue
