Story questions have level of abstraction characteristics. In the story question, it can be seen that the students’ abstract extended level by changing the pattern questions according to the indicators of high –level mathematical thinking. This study aims to determine the ability of students to understand mathematical concepts in the SPLDV material using SOLO Taxonomy-based questions and student responses in working on these questions. When researchers did a teaching practice at a vocational high school in Cirebon district, they found that the students' ability to understand concepts was still low, this was confirmed by interviews with students that they did not understand SPLDV questions, especially in making mathematical models of a story problem. This research is located in one of the Vocational High Schools in Cirebon Regency. The subjects of this study were 21 class X students. The researcher used a descriptive method with a qualitative approach because the researcher wanted to find out more about how students understood mathematical concepts in the SPLDV material using SOLO Taxonomy-based questions. The results of this study were the students' ability to understand mathematical concepts in the SPLDV Material Using SOLO Taxonomy-based questions was still very low, namely 37.10% and the responses given by students were positive for the use of questions based on the use of SOLO Taxonomy-based questions.

Innovative learning models have an influence on student achievement. This study aims to determine whether the PBL learning model is more effective than the STAD learning model (learning model that has been applied in schools) on mathematics learning achievement, whether there is a difference in the effect of the AQ of climber, camper, and quitter category students on mathematics learning achievement, and whether there is the interaction between the learning model and students' AQ on mathematics learning achievement. This research is in the form of quantitative research. The sample was taken using a simple random sampling technique where the experimental class was taught using the PBL learning model and the control class was taught using the STAD learning model. The data collection technique used the Questionnaire method for AQ data and the test method for students' mathematics learning achievement data. The data technique used a two-way unequal cell analysis of variance test with a 2×3 matrix and a further test using the Scheffe test. The results of hypothesis testing with a significance level (α) = 5% indicate that there is a difference in the effect of the learning model on mathematics learning achievement (Fobs=19.97 and Fα=4.13), there are differences in the effect of each AQ category on mathematics learning achievement (Fobs=94.59 and Fα=3.28), and there is no interaction between the learning model and students' AQ on mathematics learning achievement (Fobs=2.39 and Fα=3.28).

This study aims to describe how students 'problem-solving abilities in terms of students' mathematical dispositions on the application of the group investigation (GI) learning model. The approach used is qualitative and quantitative with descriptive types. The research subjects were 29 MAN 1 Malang class X. The data collection technique used a closed questionnaire type Likert scale, observation sheet and test questions. The results showed that learning using the group investigation learning model on mathematics learning could have a positive impact on the affective domain of students, namely mathematical disposition. The giving of the first and second disposition questionnaires increased by an average of 3.31 in the good category. Students' mathematical problem solving abilities based on mathematical dispositions are obtained by students with high dispositions who are able to solve problems properly and correctly. Students of moderate disposition can understand the problem well and provide solutions but are lacking in the solving process. Meanwhile, students with low mathematical disposition have less problem solving skills.

Problem solving is a measure or knowledge that needs to be mastered in solving problems related to real life. This ability is very important to build new knowledge as well as develop ideas. Therefore, the purpose of this study is to analyze the ability and describe the weaknesses of grade VII students in solving math problems in integer operating materials at SMP Negeri 1 Waingapu. Descriptive research type with qualitative approach. The instruments used were tests, interviews, questionnaires and documentation. The subjects of the study were the wakasek part of the curriculum, mathematics teachers and 7th grade students. The results found that the average math problem solving ability of students based on Polya steps is 59.86 and is in a fairly good category. This is because students do not write down the information encountered, do not analyze the problem first, do not write down the strategies used in solving the problem, lack of basic ability in doing calculations, difficulty in placing the sign of the calculation operation, not used to re-examine the answers that have been done and not used to write conclusions.
解决问题是在解决与现实生活有关的问题时需要掌握的一种度量或知识。这种能力对于建立新知识和发展思想非常重要。因此，本研究的目的是分析七年级学生在SMP Negeri 1 Waingapu的整数运算材料中解决数学问题的能力和描述弱点。描述性研究类型与定性方法。使用的工具是测试、访谈、调查表和文件。研究对象是wakasek课程的一部分，数学教师和七年级学生。结果发现，基于Polya步骤，学生的平均数学问题解决能力为59.86，处于较好的类别。这是因为学生没有把遇到的信息写下来，没有先对问题进行分析，没有把解题时使用的策略写下来，做计算的基本能力缺乏，计算运算的符号放置困难，没有用来重新检查已经做过的答案，没有用来写结论。

This study aims to analyze the students’ mathematical problem-solving characteristics based on cognitive style that is field independent, field dependent, reflective, and impulsive. Fourty-five students of VIII grade at PGRI 5 Junior High School were involved. The students were given 4 descriptive math problems. The result showed that the characteristics of independent field cognitive style showed that could understand the problems, determined the right problem planning, careless in solving, and did not re-check the answer. The subject could solve questions faster than the specified time, but the answer was wrong. For the characteristics of field dependent cognitive style, they could understand the problems, determined the right problem planning, careless in solving, and did not re-check the answer. The subject could not solve questions on time, but the answers tended to be correct. For the characteristics of reflective cognitive style, they did not understand the problems, determined the right problem planning, quite careless in solving, and did not re-check the answer. The subject could solve questions faster than the specified time, but the answer was wrong. For the characteristics of impulsive cognitive style, they did not understand the problems, determined the right problem planning, quite careless in solving, and did not re-check the answer.

Kehadiran pendekatan pembelajaran STEM, yang merupakan integrasi empat pengetahuan berupa Science, Technology, Engineering dan Mathematics menjadi salah satu inovasi yang tepat bagi siswa untuk membangun pengetahuannya sendiri. Namun demikian, terdapat beberapa kendala yang terjadi untuk menerapkan pembelajaran berbasis STEM, di antaranya terkait dengan persiapan pembelajaran STEM. Oleh karena itu, penelitian ini bertujuan untuk mengetahui lebih lanjut kesiapan guru-guru di Indonesia terhadap pembelajaran STEM, ditinjau dari pengetahuan mereka terhadap STEM dan pengalaman menyusun modul berbasis STEM. Metode yang digunakan dalam penelitian ini adalah metode eksploratori. Penelitian ini dilaksanakan secara online dengan menggunakan questionnaire melalui google form. Beberapa guru juga diwawancara untuk mendapatkan konfirmasi atas jawaban yang mereka cantumkan di google form. Subjek dalam penelitian ini terdiri dari 54 orang guru Matematika dan IPA. Setelah data diperoleh, data selanjutnya dianalisis secara kualitatif. Berdasarkan penelitian ini diketahui bahwa sebagian besar guru yang mengikuti survey sederhana ini belum memiliki pengetahuan memadai terkait STEM, sehingga guru masih kesulitan dalam menyusun modul berbasis STEM.
