Authors:Ali Shodikin Pages: 1 - 11 Abstract: Learning integral calculus should be done with interesting and fun process, because this course is basic materials and a prerequisite for other subjects as well as the provision of teaching materials for high school students. However, based on the documentation that have done in one of the private universities in Lamongan in the last two years shows that the average score of student results in mathematics education and mathematics subjects integral calculus has only reached 42%. This suggests that the results of student learning especially integral calculus courses still low. One effort that can be done is to develop teaching materials based animation. Media animation that comes with the animations, audio, and video in teaching and learning can grow the interest of learners. Based on these descriptions, this study aims to develop teaching materials integral calculus-based animation. This study uses a study design development consists of four stages, namely: (1) definition, (2) design, (3) development, and (4) dissemination. The end product of this research is animation-based teaching media for the course of integral calculus. PubDate: 2017-06-30 DOI: 10.24127/ajpm.v6i1.887 Issue No:Vol. 6, No. 1 (2017)

Authors:Rosmaiyadi Rosmaiyadi Pages: 12 - 19 Abstract: This research aims to test the effectiveness of Learning Cycle 7E”, the influence of learning style against the students ability of critical thinking, the best learning style of the student is critical thinking ability and description of students’ mathematical critical thinking ability in each learning style. The methods used in this research was Mixed Design Model; the Sequential Explanatory Method. The subject of this research is grade VIII. The research instrument used is the TKBKM, learning style questionnaire and interview guidelines. The effectiveness of Learning Cycle 7E it can be seen from the aspect of completeness, obtained the result that the proportion of students who got a value KBKM greater than or equal with KKM=70 have exceeded 75%, while the average difference test of experiments class and control class were t-count=6,497>t-tabel=1,671. This shows that the average students’ mathematical critical thinking ability taught by Learning Cycle 7E more than average than students’ mathematical critical thinking ability taught with conventional learning. Learning styles affect the students’ mathematical critical thinking ability, this is retrieved based on the test results of the Kruskal Wallis with Asym value sig is 0.046<0.05. The visual learning style has the best ability of mathematical critical thinking. Each learning style has advantages and disadvantages on aspects of ability of critical thinking mathematically, thus causing each learning style has differences the ability of critical thinking mathematically too.

Authors:Himmatul Ulya, Ratri Rahayu Pages: 48 - 55 Abstract: Mathematics learning in SD 1 Bae Kudus could not make students fun in learning yet. Mathematics learning was still centered on the teacher so that students had not had the opportunities to convey their mathematical ideas either orally or written. This caused the students’ mathematical communication ability were low. The goals of this study were: (1) to determine whether the mathematical communication ability of students through the application of treffinger learning using a traditional game of congklak on multiplication material reach the completeness learning and (2) to determine the quality improvement of students’ mathematical communication ability who joined treffinger learning using a traditional game of congklak on multiplication material. This study was an experimental research with one-group pretest-posttest design. The research implemented on 2nd grade ini SD 1 Bae Kudus in multiplication material. The techniques of data collection used was test to measure mathematical communication ability of students. The techniques of data analysis in the study included the analysis of data to determine the completeness learning and to analyze the improvement students’ mathematical communication ability. The results of study showed that through the application of treffinger learning using a traditional game of congklak, then (1) mathematical communication ability of students reach the completeness learning, either individually and classical and (2) students’ mathematical communication ability had increased in the medium category by 65%.

Authors:Kartika Maharani Dwi Astuti, Rubono Setiawan Pages: 56 - 67 Abstract: The problem of Addition Operation of Functions often emerges in Junior National Science and Math Olympiads at the regional level, provincial level, and national level. Non-routine questions related to the addition of functions tested In the Junior National Science Math Olympiad are more concern on the problem-solving. The questions have complex types and these types cannot directly solved by common routine procedures. Systematic-logical thinking and high level of understanding ability are required to solve the problem. There are some basic strategies which can be implemented to find the right solutions. Blended strategy plays a significant role to solve the problem. This research will discuss about the strategy to simplify equal group problem from another point of view in order to solve the addition of functions problem in the Junior National Science Math Olympiad. The implementation of the strategy is based on the Polya’s Problem-Solving Techniques. PubDate: 2017-08-05 DOI: 10.24127/ajpm.v6i1.777 Issue No:Vol. 6, No. 1 (2017)

Authors:Landyasari Riffyanti, Rubono Setiawan Pages: 115 - 127 Abstract: This study analyzed the mathematical problem solving strategy that combines a backward step and reasoned logically to answer the High School Olympic level problems related to number theory for the district, national, and provincial level which are often issued from year to year. The mentioned problem is more about the application of number theory problem, which is determine a number and the value of the questioned number. The study began by analyzing some Olympic problems. These problems are answered and resolved by a combination of mathematical problem solving strategies, which are backward step and reasoned logically. Implementation of this solving problem should also be adjusted with Polya step which is consists of four stages. Polya step is used to give better structured problem solving. Compared with trial and error method, this analyze can give an effective combination to determine a number and the value of a number.

Authors:Ira Vahlia, Yeni Rahmawati, Tri Anjar Pages: 128 - 135 Abstract: Appropriate learning models contribute to student learning interest in math. The purpose of this study is to describe the difference in effectiveness between scientific approach based on group investigation and discovery in terms of student's interest in learning. The research that is conducted is quasi experimental research and the design used is 2 x factorial description. In experimental class I that apply scientific approach model based on study group investigation obtained the average value of learning outcome of 66.60 while in the experimental class II applying the approach Science-based discovery learning obtained the average value of posttest of 76.28. Based on the marginal rate, the scientific approach to discovery-based learning on moderate interest in learning outcomes is higher than the learning outcomes at high and low interest. In the scientific approach based on group study investigation and discovery learning there are differences in average learning outcomes between high, medium and low interest. Scientific approach based on group investigation learning on higher interest in learning outcomes is higher than moderate and low interest.
