Class IX students of SMP Negeri 4 Takengon generally find it difficult to understand the mathematics learning material contained in the school textbook, besides that the teacher also feels that textbooks as teaching materials still do not help students in learning both at school and independently, so it is very necessary to have other teaching materials that can overcome this. Therefore the researcher felt that this research was very suitable to be carried out. This Research and Development (R&D) research uses the Rowntree development model whose goal is to develop math modules with the STEAM approach on curved side space material that is valid and practical for use in junior high school mathematics learning. The development process consists of three stages, namely the planning, development and evaluation stages using the formative evaluation procedure from Tessmer. Based on this development stage, a mathematics module with the STEAM approach has been produced which contains curved side geometrical material and can be categorized as very valid (content validation 4.54 and media validation 4.75) and also very practical based on one to one evaluation (teacher response 96.96% and student response 98.97%) and small group evaluation of 92.11%.

The independent curriculum requires teachers to have an enthusiastic, active, innovative, creative, and skilled attitude. One form of innovation for teachers is to create LKPD with a contextual approach that encourages students to be active and creative. However, the LKPD made by teachers is still in the form of questions and exercises that only measure the ability to answer right or wrong, and the concepts are not yet linked to students' real lives. Thus, the purpose of this service is to train junior high school math teachers in creating LKPD using a contextual approach. CBR is the method used in this service, along with practice techniques, Q&A sessions, and lectures. The three stages of an activity are preparation, execution, and evaluation. The results of the service showed that participants were able to understand and create LKPD using a contextual approach. This can be seen from the results of the pre-test and post-test evaluations that have been carried out. Apart from that, based on the service activity questionnaire that was distributed to participants, they received a positive response, and participants wanted sustainable service activities.

The research aims to: obtaining (1) a description of the types of materials , mathematical ability, and the level of complexity, (2) a description of the absorption of the material, (3) a model of matter UN in terms of NAEP as an alternative evaluation of learning mathematics. This study uses a model of Plomp development consisting of preliminary investigation, design, the realization phase, test, evaluation, and revision, and implementation phases. Type of device being developed is the UN test criteria were reviewed from NAEP and validation sheet. The device is validated experts and colleagues then tested on the subject of new students of class X-2 SMAN 2 Mranggen. The test results were analyzed with biserial correlation, product moment, Hoyt, level of difficulty and discrimination power. The first trial invalid on multiple-choice number 4, 5, 14,15, 16, and 17. Reliability in one package at a high 0.931. The second trial on multiple-choice questions that all valid. At number 7 short answer is invalid, and valid for all extended construction. Reliability on the second package of 0.904 is high. To be able to apply this test the model is necessary to develop and test further.Keywords : NAEP, Procedural Knowledge, Understanding Concepts, Problem Solving, Absorption Student
