Abstract. The research purpose is to know the process and result of development of mathematics learning instruments based on contextual teaching and learning by setting of cooperative learning two stay two stray for rectangle and square topic at seventh grade of junior high school. Learning instruments development model refers to 4D Thiagarajan models which has 4 steps namely define, design, develop, and disseminate. This research has three products namely lesson plan, worksheet, and evaluation test. Based on validation process and tryout, it can be concluded that the learning instruments had fullfiled with validity, practice, and effective criteria. Key Words : 4D Thiagarajan models, contextual teaching and learning, cooperative learning two stay two stray, rectangle and square

Abstract.Cooperative learning by using change of pairs technique is a learning model which gives chancefor thestudentstoask andstrengthentheir answerfor the exercises.This research implementscooperative learning by using change of pairs technique to reduce student’s errorin solving problems of area of trapezoid. The subject of the research is grade VII A students of SMP Negeri 7 Jember. The type of this research is a Classroom Action Research (CAR). The data collection methods used in this research are observation, documentation, interview, and test. The result shows that the errors are decreasing; misused data decrease from 50% to 0%; distorted theorem or definition decrease from 59,38% to 12,5%; technical errors decrease from 61,25% to 9,34%; and other error decrease from 27,5% to 1,25%. The result also shows that the activity of the students and the teacher in teaching and learning process are increasing. KeyWords:changeofpairs technique, students error, area of trapezoid

Abstract

Abstract. Materials to produce fertilizer are NH3 Liquid and CO2 gas. Required CO2 gas should be free from condensation, so CO2 gas is refrigerated in intercooler. In this research, we analyse of mathematic model for heat transfer in fluid with finite volume method. We will review how the CO2 gas cooling process from mathematics model point of view. We will model the equations for CO2 gas cooling process which includes momentum dan energy. After that this model will be discretizatied. For numerical solution, we will use Matlab and Fluent to simulate CO2 gas cooling process. The simulation result using Matlab and Fluent forms will be presented descriptively in charts, tables, and images to show how the distribution process of heat transfer. The result show for error is 0,0087. In conclusion the model accurate for solving heat transfer process in CO2 gas. Key Words : Mathematics Models, Heat transfer, Finite Volume Methode,

Abstract

Abstrac.: This research aims to determine the percentage of geometry questions for each van Hiele levels in the SMP mathematics textbook for seventh grade, and to determine the percentage of geometry questions for each descriptors in the SMP mathematics textbook for seventh grade based on van Hiele levels. Sources of data in the study include documents geometry questions in the SMP mathematics textbook for seventh grade, written by Tatag Yuli Eko Siswono and Netti Lastiningsih; and also Atik Wintarti et.al. To analyze the data used descriptive analysis with a qualitative approach. The result of the data analysis shows that are 1176 questions in the mathematics textbooks SMP written by Tatag Yuli Eko Siswono and Netti Lastiningsih; and also written by Atik Wintarti et.al. From the results, the percentage of geometry questions for each van Hiele levels in the mathematics textbook written by Tatag Yuli Eko Siswono and Netti Lastiningsih for Visualization, Analysis, Ordering, and Deduction are respectively 9%, 81.31%, 8.47%, and 0%. Then, in the SMP mathematics textbook written by Atik Wintarti et.al, there are 14,88% in the visualization level; 75,42% in the analysis level; 8,36% in the ordering level; and 0% in the deduction level. However, each SMP mathematics textbook for seventh grade are equally dominated by Analysis level. Then, the geometry questions in the mathematics textbook written by Tatag Yuli Eko Siswono and Netti Lastiningsih is dominated by descriptor 4.b and descriptor 9. But, in the SMP mathematics textbook written by Atik Wintarti et.al is dominated by descriptor 2. Key Words : textbook, geometry questions, van Hiele geometric thinking levels
