Abstract. This research is descriptive research with qualitative approach. The purpose of this study was to identify errors made by students of spatial, moderate, and low visual intelligence in solving math problems. The instrument used is a sheet of spatial visual intelligence test test, a sheet of flat space side wake, and interview guide. The subjects used were 2 students with high spatial visual intelligence, 2 students with medium spatial visual intelligence, and 2 students with low spatial visual intelligence. This grouping is based on the results of a spatial visual intelligence test. The student error indicators used are 5 types, including fact errors, concept errors, operation errors, principle errors, and other errors. Factual errors, operations, and principles merupapakan characteristics of visual intelligence spatial problem solving, while the error of the concept consisting of the error of drawing objects including the characteristics of the imagination and determine the pattern is a pattern search characteristics. Students with high spatial visual intelligence make a mistake of facts and operational errors. Students with spatial visual intelligence are making a mistake of facts, concept errors, operational errors, and other errors. Students with low spatial visual intelligence make a mistake of facts, concept errors, operational errors, principle errors, and other errors. When viewed from the characteristics of spatial visual intelligence, students with high spatial visual intelligence make mistakes on the characteristics of problem solving, students with spatial visual intelligence are making mistakes on the characteristics of imagination, conceptualization, problem solving and pattern searching, as well as students with low spatial visual intelligence performing the same thing. Key Words: Spatial Visual Intelligence, Student Error Identification, Geometric the Flat Side

Abstract: The purpose of this research is to descripbe about autistic students’ thinking process in solving contextual problem standards based on Suryabrata teory’. The data by giving test contextual mathematic problem which integers operations subject. Problem given to autistic students of class VIII SMPLB TPA Jember, amounting to four students. Problem given first validated by 2 doses of mathematics education and 1 math teacher SMPLB TPA Jember. . Data analysis can be observed from students’ work sheet. Student’s answers analyzed according to the components of Suryabrata Teory’. Suryabrata teory’ consists of three components which are (1) forming understanding; (2) forming opinion; (3) drawing conclusion. The results of this study is, autistic students tend to meet the second component of the theory Suryabrata. This is directly proportional to the theory that autistic students have exceptional ideas in solving a problem. Autistic students have difficulty in fulfilling the first and third components of the Suryabrata theory. This is directly proportional to the theory that autism students have difficulties in communication Keywords : Thinking Processes, Autistic students, Integers Operations

Abstract. Learning media is a tool to deliver the materials to students during teaching and learning process. This study aims to develop e-comic learning media on linear program of two variable. The process of developing this learning media refers to the Thiagarajan model known as the 4-D model which consists of four stages, namely define, design, develop and disseminate. The results of the comic media validation included in the valid criteria with a correlation coefficient value was 0.91. Based on the trials that have been conducted in Class X-MIPA 4 MAN 1 Jember with a total of 24 students, the results of the use of instructional media including the level of practicality are categorized as good with a percentage was 91.2%. Then the effectiveness results of comic media based on cognitive, psychomoto, and affective aspects obtained effectiveness level of "Good" in all aspects. Cognitive aspects show a percentage of students who scored above the standard score was 75%. The percentage on the student observation sheet was 87% in the psychomotor aspect. The last aspect is affective with a percentage was 93.75%. Keywords: E-Comic, Learning media, Linear Program of Two Variable, Thiagarajan model

Abstract

Abstract.Problem Based Instruction is kind of learning model which introducing students to a real and meaningful problems. The phases of PBI are (1) orientating the students to a problem, (2) organizing the students to learn, (3) guiding the individual or group research, (4) developing and presenting the result, (5) analyzing and evaluating problem solving process. This research aims to develop the set of learning, such as syllabus, lesson plan, student book, student worksheet, and evaluation test by using Thiagarajan Model which consist of four steps such as define, design,develop, and disseminate. But this research just use the three of them, without disseminate step. SMP Negeri 3 Jember is elected as the research place. The coefficient validities of syllabus, lesson plan, student book, student worksheet, and evaluation test respectively are 0,975; 0,982; 0,984; 0,980; and 0,992. Since all of those coefficient more than 0,6, so we can conclude that the set of learning is valid and proper to be used. The reliability coefficient of evaluation test is 0,612717. Besides, the each item validity of evaluation test also showed a high number. There are five item problems where the coefficient validities of each number are 0,819533; 0,98036; 0,958226; 0,894288; and 0,960059.
