Abstract
The cooperative learning model is a teaching strategy that emphasizes attitudes or behaviors in working or helping among others in the structure of regular cooperation in groups, consisting of two or more people. The problem in this study is whether the application of the STAD cooperative learning model influences students mathematics learning achievement. This study uses the experimental method, using the experimental group of the STAD type cooperative learning model while the control group uses conventional/ordinary learning models. The population in this study was all students of SMA 1 Cibatu class 1, while the samples were two randomly selected classes from 6 existing classes. The instrument is used in this study is a set of description type test questions. To test the hypothesis, the Mann-Whitney test is used and from the test results it is obtained that Zhitung is -3.47 and Ztabel is 2.575 with α = 1%. It turns out that with the -Ztabel < Zhitung < Ztabel H0 is in the rejection area, it means that there is a significant difference in final ability between the experimental group and the control group. So it can be concluded that there is the influence of the STAD cooperative learning model on students mathematics learning achievement.

Abstract
This study aims to analyze the improvement of geometric reasoning abilities of students of SMA Negeri 1 Sampara, Konawe Regency, Southeast Sulawesi, Indonesia. Here, we compare three models of learning; (1) GeoGebra assisted STAD cooperative model; (2) a model of the STAD cooperative without assistance from GeoGebra; and (3) direct learning models. This study was applied to three different classes, where each class consisted of high, medium and low motivation students. Data collection was done by giving a mathematics learning motivation questionnaire and giving a test of students geometric reasoning abilities. Meanwhile, the data analysis technique uses inferential statistics to test normal assumptions and homogeneity and hypothesis testing using the One-Way ANOVA Test. Based on the results of the study showed that the effect of using the STAD type cooperative learning model with the help of GeoGebra was higher when compared to the other two models. That difference occurs at all levels of motivation. On the other hand, the STAD model without GeoGebra only affects high and moderate motivation students. Meanwhile, low motivation students did not show significant differences with the direct learning model.

Abstract
The learning approach and classroom assessment techniques in the learning process are activities that must be carried out by the teacher to know students- achievement. The paradigm of the learning approach must have changed from student-centered to teacher-centered learning. One of the learning approaches that can be used by teachers in mathematics learning is realistic mathematics learning. In this approach, besides students are required to be active in their learning also learning activities emphasize the problems faced by students every day. In addition to the learning approach, the use of classroom assessment techniques can also determine student-s creativity in learning. Student-Generated Test Question (SGTQ) and Application Cards (AC) are examples of alternative classroom assessment techniques that teachers can use in addition to the classroom assessment techniques that have been used so far. The use of SGTQ and AC as a classroom assessment techniques allows students to think creatively and think higher in learning mathematics. The objective of the research is to find out the effect of learning approach and classroom assessment techniques toward student-s mathematics achievement. It was a quantitative research with an experimental study conducted in the State of Islamic Junior Secondary School (MTsN) of Cening and State of Islamic Junior Secondary School (MTsN) of Pandeglang 2 Labuan, Pandeglang. The students- mathematics achievement was seen at the end of the semester using the test. In this case, we will discuss the implication of learning approach and classroom assessment techniques for students- mathematics achievement. The result of this study indicates the influence of the use of the learning approach and classroom assessment techniques on students- mathematics achievement.
