The 2013 curriculum is developed with refinements of mind-set, one of them is a reinforcement of multidisciplinary learning, or commonly known as STEM (Science, Technology, Engineering, and Mathematics). Learning tool as one of learning support facilities also should be developed following the development of the 2013 curriculum. However, STEM learning tools are still unavailable. STEM implementation can be successful if supported by programs that are based on best practices for program design. One of the learning models that support them is PjBL (Project Based Learning). Also, there is an ability that is closely related to STEM implementation, namely spatial ability. Therefore, the purpose of this research was to develop STEM learning tools through PjBL to improve students’ spatial ability which valid. Learning tools developed were lesson plans, project worksheets, student worksheets, AutoCAD 2D Guideline, and spatial ability tests. This research was development research. The instrument used was validation sheets. The validation phase STEM-PjBL learning tools consisting of lesson plans, project worksheets, student worksheets, and spatial ability tests consisted of two phases. It was because only three of five validators who stated that the learning tools had been possible to use with minor revisions in the first phase. These results indicated that the learning tools were not however valid. As a result, the learning tools needed to be revised following the comments and suggestions provided by the validators. After that, the learning tools were validated again by the validators. The second phase validation result was all validators stated that the learning tools had been possible to use. In contrast to these tools, the AutoCAD 2D Guideline was only validated once because, in the first phase validation, all validators stated that the AutoCAD 2D Guideline was worth using with minor revision. Thus, STEM-PjBL learning tools to improve students' spatial ability have met the valid criteria.Keywords: development, learning tools, STEM, project-based learning, spatial ability.

One of the competencies which students must possess is a mathematical understanding. Another aspect that supports understanding is self-concept. An effort that can be taken as a solution for improving students’ understanding and the self-concept is a model of learning which can lead students to find their concept. This model is often called discovery learning. This study aims to improve students’ mathematical understanding and the self-concept through the discovery learning model. In this study, the researcher used quantitative research. The population of this study was all senior high school Ulumuddin students in the 2016/2017 school year. The sample of this study was 40 students in grade 10 who were randomly chosen from two classes. The data in this study were obtained using instruments compiled in the form of questionnaires and tests that were answered by the respondents. The results showed that the improvement of students’ mathematical understanding and self-concept who obtained learning with the discovery learning model was better than students who gain learning without using the model of Discovery Learning. However, there was no interaction between the model and the levels of understanding and the self-concept of students.Keywords: mathematical understanding, self-concept, discovery learning.

Belajar matematika, ketika hanya terfokus pada perhitungan angka, akan datar, kehilangan keindahan dan kebermaknaan, terutama angka dan operasinya. Seseorang yang belajar matematika diperlukan adanya kepekaan terhadap angka dan operasinya. Para ahli menyebut jenis sensitivitas sebagai sensitivitas angka. Para ahli mengatakan, jika seseorang memiliki nalar yang baik, matematika akan menjadi indah dan menyenangkan, sehingga konsep itu menjadi lebih baik. Sensitivitas akan angka membantu seseorang untuk melihat logika dari hasil perhitungan, sehingga semangat matematika akan ditemukan, dan matematika akan bermakna bagi siswa. Ada beberapa orang berpendapat bahwa matematika itu membosankan. Kondisi ini memiliki efek negatif pada pemahaman matematika seseorang. Penelitian ini bertujuan untuk melihat bagaimana strategi siswa di SMKN Penerbangan Aceh dalam memecahkan masalah. Penelitian ini menggunakan pendekatan kualitatif dengan menggunakan teknik purposive subjek.

Indonesia is an archipelagic country lies on the Pacific Ring of Fire, resulting in the country being vulnerable to disaster. Teachers need to accustom students to manage natural disaster situation in a more logical approach. Therefore, it is necessary to develop mathematical problems in disaster contexts. This research is an early stage of developmental research. The purpose of this study was to analyze the needs of teachers and students of mathematical problems in disaster contexts. The participants in this study were a mathematics teacher and 53 Year 7 and 8 students at one of the public junior high school, located in a Tsunami affected area, in Banda Aceh. Data collection involved an open questionnaire, and data analysis was carried out descriptively. The results showed that the teacher often provided mathematical problems in learning but had never read mathematical problems in disaster contexts. Also, only three students had ever read such problems. The results also revealed that nearly half of the students (41.5%) liked to solve mathematical problems. Besides, both the teacher and 71.7% of the students agreed and were willing to participate in the learning process involving mathematical problems in disaster contexts. The results of the study also showed that the mathematical questions in disaster contexts were limited. Thus, it is necessary to develop mathematical problems in disaster contexts.
