The outcomes of situation analysis in SMP Negeri Kota Baru Kefamenanu East of Nusa Tenggara is the low achievement of students' mathematics learning outcomes seen from the evaluation results of mathematics subjects in the last four semesters and low learning motivation based on the results of teacher interviews. Therefore, we need an activity that aims to conduct training on math problems for grade 9 students and increase student motivation in learning mathematics. The drill method is a method for giving problems repeatedly. This method is considered relevant to the purpose of community service activities. The stages of community service activities begin with giving a pre-test, giving training on math questions, giving a post-test, and ending with giving a questionnaire regarding student motivation. The result of the community service activity was that there was an increase in students' understanding in working on math problems seen from a comparison of the results of the pre-test (29.05%) and post-test (94.76%) and students were increasingly motivated in learning mathematics refer to the results of the questionnaire. Based on the evidence, it’s crystal clear that service community activity is useful for training students to solve non-routine math problem and motivating students to learn mathematics.

The background of this research is the learning obstacles that arise on the topic of determining the solution of a system of linear equations (SLE) in applying elementary row operations (ERO). From these findings, it is necessary to formulate a hypothetical learning trajectory (HLT) that can guide the flow of thinking in designing didactic situations in the learning process. HLT expect to anticipate learning obstacles (LO) that arise. This research is a preliminary design of a series of didactical design research. The steps taken in compiling the HLT are 1) reviewing the lesson plan, the methods used to convey the material to determine SST solutions, and the textbooks used; 2) reviewing students' thinking processes conceptually and procedurally regarding theoretically determining SLE solutions; 3) reviewing design plans didactic. HLT is formulated into five types of student responses. It integrates into didactic situations by explaining the relevance of the elimination method in high school with three operations on ERO and then by explaining matrix material before SPL material. From this didactic situation, it can be formulated in teaching material that can accommodate emerging LO.

The research belongs to a qualitative descriptive study that aims to describe the numeracy literacy skills students grade 8 of State Junior High School of Kota Baru I (SMPN Kota Baru) in terms of their cognitive styles. The subjects of this study were eight students representing students with reflective cognitive styles yet impulsive cognitive styles. Data collection techniques were, matching familiar figure test (MFFT) to classify students based on their cognitive styles, numeracy literacy tests, and interviews. Data analysis techniques used were data reduction, data presentation, and drawing conclusions. The results of this study showed that the level of numeracy literacy skills of reflective students (SR) was respectively SR 1 is 88%, SR 2 is 67%, SR 3 is 79% and SR 4 is 91%. The level of numeracy literacy skills of impulsive students (SI) was respectively SI 1 is 58%, SI 2 is 67%, SI 3 is 50% and SI 4 is 63%. Reflective subjects have a category of high and very high numeracy literacy ability levels while impulsive subjects have a category of medium and high numeracy literacy ability levels. Reflective students need a long time to understand the problem by describing it into a mathematical model so that reflective students excel in the reasoning aspect. Impulsive students tend to be quick in answering questions but pay less attention to the right answers so that impulsive students stand out in the communication aspect.
