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

Discovery learning is a learning that involves students in the process of mental activity through a brainstorm, to discuss, and try it yourself, so that children can learn to be independent. Resulting in the discovery-based learning problem solving is to let children discover things on their own and group investigation that emphasizes problem solving based on a debriefing activities and student participation. The classes drawn into the sample, the class as a class given control based discovery learning and problem solving one class another group investigation given learning-based problem solving. Data analysis techniques in this study using Ttes. From the results of this study concluded that: (a) In the first experiment class that implements learning model-based problem solving group investigation obtained average value of learning outcomes at 73.10 while the experimental class II implementing discovery-based learning problem solving obtained average value postest average of 66.55. (b) There are significant differences between the results of student learning in the class that implements the discovery-based learning and problem solving class that implements the learning model based problem solving group investigation. Student results in learning problem solving based group investigation better on the class that implements the model-based discovery learning problem solving.Â Keywords: discovery learning, group investigation, learning numerical methods, Â problem solving

#### Abstract

In the process of learning mathematics, mental retardation student require certain methods, strategies, and teaching materials that can help in overcoming difficulties during the learning process, including in learning mathematics. The importance of learning that presents the real world or the nature around in learning is expected to help the student in achieving learning goals in mathematics. The absence of mathematical teaching materials that can bring the real world to the childs mental retardation into the learning of mathematics. Learning that can bring the real world into learning is realistic mathematics education (RME). It is hoped that the existence of teaching materials based on realistic mathematics can help the difficulties faced by students of mental retardation in the process of learning mathematics. The research that has been carried out at this stage resulted in the worth of materials that are suitable to be used from six validator. In developing this teaching materials using the stage of research and development is the stage of existing product analysis, design stage design, internal test stage (expert validation), test phase (limited test and field test). Development stage that has been done is internal test stage that is expert validation. From the results of the study can be concluded that RME-based mathematics teaching materials that have been developed the criteria worthy of use based on the validation of six validators. This teaching material obtained an average validation value of 80.25% in the Eligible category.
