Abstract. The purpose of this study was to determine whether using the TPS learning model by using LKS can improve student learning outcomes in the material system linear equation two variable in class X Senior High Public School 2 of Pematangsiantar. The type of research used is classroom action research with 2 cycles. Subjects of class X-IPA 7. On the implementation of the first cycle of action, the result of the analysis of tests of students at the moderate (≥ 65) category in a classical manner were still not achived because only 52.78% of students were completed, with a grade average 65.00. After the implementation of the second cycle of action, the learning outcomes of students in the medium minimum category (≥ 65) have been achived classically, namely 86.11% with an average value 73.75. The increase in students’ mathematics learning outcomes from cycle I to cycle II was 21.11%. Based on the result of the above research it can be concluded that the application of the TPS learning model using LKS can improve student learning outcomes.Keywords: Laerning Outcomes, Think Pair Square (TPS), LKS

Abstract. The purpose of this study was to find out: (1) Is the increase in mathematical critical thinking abilities of students given the guided discovery method assisted by Geogebra software higher than students who were given guided discovery method learning without Geogebra software, (2) Are their interactions between learning with students 'initial mathematical abilities towards improving students' critical thinking skills. This research is a quasi-experimental study. The population of this study is that all classes in the fourth-semester mathematics education study program are approximately 120 people. Randomly, two classes were chosen from four classes. The experimental class was treated with Geogebra assisted guided discovery methods and the control class was treated with a guided discovery method without the help of Geogebra. Data analysis was performed by analysis of two-way variance (ANAVA). The results showed (1) Improvement of mathematical critical thinking skills of groups of students who obtained guided discovery method learning using GeoGebra software was higher than the group of students who received learning through guided discovery methods without GeoGebra software. (2) There is no interaction between the learning model and the initial ability of students in improving students' critical thinking skills in mathematics.Keywords: Critical Thinking Ability, Guided Discovery Method, Geogebra

Abstract. This study aims to determine whether there are differences in mathematical problem solving abilities of students who are taught through an investigative approach and with conventional approaches in class VIII SMP 9 of Pematangsiantar. This type of research is experimental research. The population in this study were all eighth grade students of SMP 9 of Pematangsiantar as many as 8 classes. The problem solving abilities of students taught with an investigative approach to the average pretest of 57.73 and post-test of 85.42, the level of change in problem solving abilities was 27.69. Higher than the problem solving abilities of students who are taught with conventional learning the average pretest is 56.67 and posttest is 72.67. Hypothesis testing, from the calculation of student pretest data obtained at dk = 64 and the real level α = 0.05 and ????(1−12∝)=????0,975 obtained ttable = 1.669 and tcount = 1.172. Because tcount ttable = (1.172 1.669) it can be concluded that the initial ability of students is the same. While based on the calculation of student posttest data obtained at dk = 64 and the real level α = 0.05 obtained ttable = 1.669 and t count = 4.212. Because tcount ttable (4.212 1.669) then Ho is rejected and Ha is accepted. Then it was concluded that there were significant differences between problem solving abilities taught by an investigative approach and conventional approaches.Keywords: Problem Solving Ability, Investigative Approach, Conventional Approach.

Abstract. The purpose of this study is to find out the effect of cooperative learning type Think Pair Share on student learning outcomes in basic mathematics introductory courses at the FKIP PGMS UMSU Study Program. This study was a quasi-experimental study, using the one group pretest posttes only model, using one class as the study sample. The research instrument used in this study was a test / quiz in the form of 23 objective / multiple choice questions about set material and relationships contained in the basic mathematics introductory course. Based on the data obtained from the research results, there is an increase in the quality of learning in two stages, namely before the application of the Think Pair Share learning model and after the application of the Think Pair Share learning model. It can be seen that the values obtained by students at the post-test stage are superior and than before the application of the Think Pair Share learning model. The research hypothesis testing is related to how much influence the application of Think Pair Share learning models to improving student learning outcomes is done through statistical tests / t test. The result, obtained Tcount = 3.64. Then compared with Ttaraf at df = n-1, df = 42-1 = 41. With a real level of α of 0.05 is 2.02, if the price of Tcount is compared to T(table). It turns out Tcount T(table) (3.64 2.02). This figure shows that the Think Pair Share learning model has a positive effect on the ability to understand the subject matter of Basic Mathematics Introduction for students of the FKIP UMSU PGSD Study Program.Keywords: Think Pair Share, Basic Introduction to Mathematics

Abstract. Computers are essential tools for teaching, learning, and doing mathematics. Computers can visualize or represent mathematical ideas, organize and analyze data, and calculate effectively and accurately. Computers can help students conduct investigations through representations in various fields of mathematics such as geometry, calculus, statistics, algebra, measurements, and numbers. This paper discusses the role of Maple assisted representation in calculus learning. Representation is very supportive in increasing students' understanding of mathematical relations and concepts. There are three main functions of representation, namely complementing, constraining, and constructing. Complementing function is to complete the process and complete the information. The constraining function is to help students experience difficulties in a representation. The constructing function is to support constructing a deeper understanding of a concept. Students can get a deeper understanding if difficulties with only one representation. Maple software is a facility that is very supportive in making representations in learning mathematics as in calculus learning. By using Maple we can do numerical and symbolic calculations and perform graphical representations well. Maple can also effectively determine limits, derivatives, integrals, and a series of other functions and capabilities. With this Maple software capability, we can use it to improve students' understanding of calculus courses.Keywords: Representation, Computers, Maple, Calculus
