ANALISIS KEMAMPUAN KOMPETENSI STRATEGIS MATEMATIS SISWA PADA MATERI PERSAMAAN DAN PERTIDAKSAMAAN LINEAR SATU VARIABEL

The object of this research is to understand the strategic competence of the students in the parallel materials and linear equations of one variable in the SMPN 3 Karawang Barat in solving the story quiz. The eighth-graders of SMPN 3 Karawang Barat are the subject of this report. It is a qualitative study with a descriptive approach. A method for data collection is the strategic competence test. The student's assessments are scored and the problem analysis is carried out to understand the markers of a strategic mathematical skill that requires the ability to understand the situation and conditions of a problem, to choose an acceptable presentation to help solve the problem. Research indicates that the student category already able to fill all of the indicators of mathematical strategic competence is 18.9%, the student who has been able to fill some indicators is 67.6% and the student who has not yet been able to fill all indicators is 13.5%. Therefore, the strategic competence of mathematically of class VIII H of SMPN 3 Karawang Barat is still in the moderate category

Longitudinally adaptive assessment and instruction increase numerical skills of preschool children

Social inequality in mathematical skill is apparent at kindergarten entry and persists during elementary school. To level the playing field, we trained teachers to assess children’s numerical and spatial skills every 10 wk. Each assessment provided teachers with information about a child’s growth trajectory on each skill, information designed to help them evaluate their students' progress, reflect on past instruction, and strategize for the next phase of instruction. A key constraint is that teachers have limited time to assess individual students. To maximize the information provided by an assessment, we adapted the difficulty of each assessment based on each child’s age and accumulated evidence about the child’s skills. Children in classrooms of 24 trained teachers scored 0.29 SD higher on numerical skills at posttest than children in 25 randomly assigned control classrooms (P= 0.005). We observed no effect on spatial skills. The intervention also positively influenced children’s verbal comprehension skills (0.28 SD higher at posttest,P< 0.001), but did not affect their print-literacy skills. We consider the potential contribution of this approach, in combination with similar regimes of assessment and instruction in elementary schools, to the reduction of social inequality in numerical skill and discuss possible explanations for the absence of an effect on spatial skills.

Learning Mathematics: One Minute

This game is made with purpose to educate student in terms of mathematical skill combined with fun adventure game. The target audience is the students should be primary-school (10-13 years old). This is an educational game and made on purpose to create a difference method to present solving a mathematical problem to the audience. The user will play a game where the character is chased by a dog and must avoid obstacles such as river. In each level of the game, the user must find a door in which they must solve the mathematical question as pass code. Successful in solving the mathematical question will bring user to another level. This game is made with 3 level and must be completed within 1 minute. This game can be used as a tool for learning. The level of mathematical questions is simple mathematical quiz, designed with objective to teach early age students.

Programming as a mathematical activity

Programming in undergraduate mathematics is an opportunity to develop various mathematical skills. This paper outlines some topics covered in a second year, optional module ‘Programming with Mathematical Applications’ that develop mathematical thinking and involve mathematical activities, showing that practical programming can be taught to mathematicians as a mathematical skill.

Analysis On Written Mathematical Communication Skills At System Of Linear Equations In Two Variables (SLETV) Material Viewed From Student Learning Styles

This research was to describe students’ mathematical communication skills based on their learning styles. This research was a descriptive research with qualitative approach. Data was obtained in three steps, namely written test on SLETV material, questionnaire on learning styles, and interviews. Research subject was eighth grade students. The procedure in this research began with the pre-field stage. At this stage, the research was designed, starting from observation and interviews with the teacher, as well as discussion with the supervisor. The second was the field stage, which was the stage for conducting research. The final stage was writing the report, which was the stage where researchers have conducted the research, processed and analyzed data that has been obtained from the research. Data collection techniques in this research were distributing questionnaire, giving test questions about SLETV, and conducting interviews to find out the students’ mathematical communicationskills more specifically. The instruments in this study were questionnaire onlearning styles, test questions about SLETV, and interview guide sheets. Dataanalysis techniques in this research aimed to achieve data reduction by sorting out important answers from student results in the form of questionnaire, test, and interviews. Data presentation was in the form of narrative texts. Interviews were aligned with the test questions about SLETV. Finally, conclusions were formulated by describing each student’s written mathematical skill based on the 4 student learning styles. Based on the results, students with interpersonal learning style had the ability to learn better through friendship, students with self-expressive learning style had the ability to learn by paying more attention to the final results and tended to use unusual ways to find the best results, students with understanding learning style had the ability to see facts and remember large amounts of knowledge, ideas, theories, or concepts, while students with mastery learning style were able to write to the point and focus more on results.
