Abstract

The ability to solved problems is an important element in learning mathematics. But in reality at SMPN 13 Mataram this ability still low with a percentage of 70% of students having low problem solving abilities. The reason is teachers tend use same learning methods and students also not know how to optimize their own potential in learning. One way to make learning mathematics effective is by knowing learning styles used by students. This study aims to describe the problem-solving abilities claass VIII at SMPN 13 Mataram based on learning styles. The type of research used is qualitative research with research instruments namely problem solving ability tests, learning style questionnaires and interviews. The results obtained from 28 students were students with 12 students in the visual style category, 15 auditory students and 1 student with a kinetic learning style. The conclusion from the research results is that from the four stages of problem solving based on the theory of polya. , The visual learning style is able to complete the four stages very well. Auditory learning styles can only complete the 3 stages well and do not do the re-checking stage. In the kinetic learning style, it can only solve one problem and does not carry out the rechecking stage. The main difference between these three learning styles is the accuracy in problem processing.

Abstract

A good learning process is one that can help students construct their knowledge, skills, and attitudes to solve every problem in their daily lives. To achieve such a learning process, the Think Pair Share learning model is needed as an alternative solution. The purpose of this study was to determine the effect of the Think Pair Share learning model on high school students' physics learning outcomes. This study was a quasi-experimental study with a pre-test post-test control group design. The research population consisted of all students at one of the senior high schools in Sumbawa, while the research sample was divided into two groups of 11th-grade science students: the experimental group and the control group. The research instrument used was a test. The data were analyzed using a t-test at a significance level of 0.05. The results showed that the physics learning outcomes of students in the experimental group were higher than those in the control group, and the calculated t-value was > t-table, namely 6.430 > 1.684. Therefore, it can be concluded that the TPS learning model has an effect on the physics learning outcomes of high school students.

Abstract

The problem of scheduling learning activities at SMKN 4 Mataram is the same teachers are scheduled at the same time in two class or more. The coloring graph concept can be used to find out the causes of the scheduling problems at SMKN 4 Mataram. Based on result of the application coloring graph concept generated  to the chromatic number is 23 with slots number is 46 which is smaller than 55 or  time slots  at SMKN 4 Mataram. Because slots of chromatic number are smaller than the time slots at SMKN 4 Mataram, it is known that the causes of scheduling problems at SMKN 4 Mataram are wrong scheduling way. One of solution to this problem is to compile a schedule based on the coloring graph concept by mapping 419 subjects with 84 teachers and 55 time slots spread from Monday to Saturday. In applying the coloring graph concept, the Largest Degree Ordering (LDO) algorithm is used. It is because this algorithm is simpler than other algorithms.
