Abstract: This research aimed to know: (1) which of the NHT modified model, the NHT model or the direct learning model promoted the students? better achievement on mathematics, (2) which one is better, the students with visual learning style, auditorial learning style, or kinesthetics learning style, and (3) in various learning style, which one having better achievement on mathematic, the NHT modified model, the NHT model or the direct learning model. This research was a quasi-experiments research with factorial design 3x3. The population of this research was the eight grade students of State Junior High Schools in Ponorogo. The sample was taken by the use of stratified cluster random sampling technique. The data collecting made use the documentation, questionnaire, and test methods. The documentation method was used to collect the data of the second-semester students? achievement on mathematics in the academic year 2011/2012 as found in their report books. This finding was further applied to check the balance of the students of the two exsperiment classrooms and one control classroom. The questionnaire was used to find the type of learning style mostly owned by the students. Whiles, the test was used to determine the students? achievement on mathematics in the straight line equation topic. Examination of hypothesis used an unbalanced two way analysis of variances at significance levels 5%. The results of the research was as follows: (1) the students? achievement on mathematics due to NHT modified model was equally due to NHT model, while the two models above was better than due to direct learning model, (2) there was no distinction among visual learning style, auditorial learning style, and kinesthetics learning style based on the students? achievement on mathematics, and (3) in various of learning style, the students? achievement on mathematics due to NHT?s modification model was equally due to NHT model, while the two models above was better than due to direct learning model.Keywords: the NHT Modified, the Direct Learning Model, the Learning Style

Abstract

Abstract:The aims of the research is to describe the thinking process at senior high school students in solving the application problems of the derivative function viewed from personality type choleric, sanguine, melancholies, and phlegmatic. The research was a descriptive qualitative. The subjects of the research was students of class XII Senior High School 1 Surakarta consist of one student for each personality types. The prosedure of selecting the subjects used purposive sampling. The data of the research was collected by using think aloud method. The validity of the data used was triangulation. Technique analyzing of the data were: (1) classifying the data into three categories: (a) understanding the information, (b) solving the problems, (c) convincing the answer, and then reducing the data, (2) presenting the data, and (3) concluding the data in each categories. The results of the research showed that thinking process for, (1) choleric student: (a) reading and creating an image, understanding information and question, (b) devising solution, connecting the first equation with the planned solution, solving the problem and only using one way solution, (c) substituting the answers into the first equation and determining maximum value of the function, (2) sanguine student: (a) reading and looking, then creating an image, understanding information although having difficulties and understanding question, (b) devising solution, connecting the first equation with the planned solution, solving the problem although having difficulties and using the other solution, (c) substituting the answers into the first equation and adjusting the answers with the problem in question, (3) melancholies student: (a) reading repeatedly, then creating an image, understanding information although having difficulties and understanding question, (b) devising solution, connecting the first equation with the planned solution although having difficulties, solving the problem and using the other solution (c) determining maximum value of the function, (4) phlegmatic student: (a) looking and then creating an image, understanding information and question, (b) devising solution, connecting the first equation with the planned solution although having difficulties, solving the problem and only using one way solution, (c) looking back at the anwers and adjusting with the actual event.Keywords: thinking process, problem solving, personality type Typology Hippocrates-Galenus

Abstract

Abstract: The aim of the research was to describe planning and implementation of the learning process performed by mathematics teacher in the class VIII acceleration of SMPN 1 Boyolali. It was a qualitative research casestudy.The subject of this research were taken by using the purposive sampling. The subject of the research were mathematics teacher class VIII acceleration fisrt grade and second grade. The techniques of collecting the data in this research were documentation, interview and observation. The techniques of validating the data were source triangulation and time triangulation. The technique of analyzing the data was Miles and Huberman concept, namely, data reduction, data presentation, and conclusion drawing. The findings of the research show that planning of the learning process performed mathematics teacher in the class VIII acceleration of SMPN 1 Boyolali equal to the planning process of mathematics learning in the regular classroom, the difference lies in the allocation of time. The process of preparation of instructional time allocation in accelerated classes every basic competence with respect to the number of weeks was effective as seen from accelerated academic calendar, the number of basic competencies, depth, complexity, and level of interest of a basic competence. Implementation of the learning process performed mathematics teacher in the class VIII acceleration of SMPN 1 Boyolali, approaches, strategiesandmethods, is student-oriented activities. The approachused by teachersis the approach behaviour (behaviour therapy). Learning strategies are instructional strategies that emphasize learning out comes in intellectual abilities and learning strategies student-oriented activities. The method is applied teacher combines several methods such as lectures, question and answer, discussion and drill that emphasize student activity. Keywords: planning of the learning process, implementation of the learning process, syllabus, lesson plan, learning approaches, learning strategies,  learning methods, acceleration
