Abstract. The purpose of this study was to find out: (1) Is the improvement in students' understanding of mathematical concepts given guided discovery method assisted by software Autograph higher than students who were given guided discovery method learning without Autograph software, (2) Is there an interaction between learning with students' initial mathematical ability to increase the ability to understand student mathematical concepts. 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 184 people. Randomly, two classes were selected from six classes. The experimental class was treated with a guided discovery method assisted by autograph and control class given a guided discovery method without the help of autograph. The instrument used is a description test. Data analysis was performed by analysis of two-way variance (ANAVA). The results showed (1) Increased ability to understand mathematical concepts of groups of students who obtained guided discovery method learning using Autograph software higher than the group of students who received learning through guided discovery methods without software autograph. (2) There is no interaction between the learning model and the initial ability of students to increase the ability to understand students' mathematical concepts.Keywords: ability of concept understanding, Guided Discovery Method, Autograph Software.

AbstractThe research aimed to increase student’s mathematics learning of SMA Negeri 1 Tambang grade X5. This research was conducted on 36 students of grade X5 in SMA Negeri 1 Tambang through cooperative learning with approachment Think Pair Square (TPS) and Two Stay Two Stray (TSTS) technique. The material is about Linear and Quadratic Equation. This research was classroom action research. The subjects of this research was 36 students of grade X5 in SMAN 1 Tambang. The object of this research was to increase the student’s mathematics learning through Cooperative Learning with structural approachment TPS and TSTS technique for linear and quadratic equations. The instrument of this research was the student’s Mathematic result, observation, and interviews. The observations aimed to determine the researcher’s ability to manage the process of learning to determine the student’s prior knowledge was taken from student’s test before learning it was 15 (41.67%) of student reach KKM. After giving the cooperative learning with the structural TPS and TSTS technique, then giving the mathematics learning result (daily tests I). From the results of UH I data showed that as many as 20 (55.56%) students achieve KKM. Because of the results of students' mathematics learning as a whole has not been reached then resumed action on the second cycle. From the results of UH II data showed that 27 (75%) of students who reached the KKM. This means an increase in students' mathematics learning results from the first cycle to the second cycle.

Abstract. This study aims to determine the improvement of students' mathematical communication skills with the implementation of the 2013 curriculum on linear program materials in grade XI SMA Negeri 2. This type of research is a classroom action research. This study measures students' mathematical communication skills. The test instrument of mathematical communication ability given to the students with the form of the test essay has been done by validating the instrument test and it is stated that the quality of the research instrument is significant, because by using the product moment formula obtained the lowest validity calculation 0.279 (low validity) and highest validity coefficient 0,829 (validity High) so that each test item is valid. Based on the conclusion of data obtained that the students' oral mathematical communication ability increased from 85% in the first cycle that is 34 students get good criteria and 6 students get enough criteria to be 90% in cycle II that is 36 students get good criteria and 4 students get enough criteria. While the student's mathematical communication ability increased from 62,5% in cycle I that is 25 students get good criterion and 15 students got enough criteria become 87,5% in cycle II that is 35 student get good criterion and 5 student get enough criteria.

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

MES: Journal of Mathematics Education and Science Vol 3, No 1 (2017)
Publisher : Universitas Islam Sumatera Utara

Self-efficacy is a person's feelings, ways of thinking, self-motivation, and desire to have something, while a positive attitude means in the learning process students have a tendency to accept or reject a concept or idea, if not in accordance with his mind. Students can think and be positive if if a learning can provide real benefits for life. While the academic achievement is the result of behavioral changes that include the cognitive domain, affective domain and psychomotor domain which is a measure of student success after being given treatment or learning. This research was conducted at SMK Negeri 1 Sipirok. This study uses descriptive research method with correlational approach with the aim to know whether there is a significant relationship between self-efficacy and positive attitude toward student academic achievement. Based on the research that has been done, the research results found that there is a significant relationship between self-efficacy and positive attitude of students to the academic achievement in SMK Negeri 1 Sipirok Tapanuli Selatan but the relationship is not showing increase or decrease so it can be said academic achievement is not important enough in pushing self-efficacy and positive attitude of students.
