Abstract

Algebra has an important meaning in Senior High School learning. It needs to be combined by the interesting practice questions, with that reason, this research will develop a board game learning media that can be used in Algebra learning. The research aims to develop a board game learning media that is valid, practical, and effective as a means of training questions in Algebraic material. The research uses the ADDIE development model which consists of steps Analyze, Design, Development, Implementation, and Evaluation. This media is a set of the modified game from monopoly games. This media is named The Adventure Of Algebra, and has been tested on 34 class VIII C students of SMP Negeri 1 Ambarawa. The instruments of data collection technique in the research consisted of instruments for validating material and media aspects, practicality assessment instruments, student opinion instruments, and posttest pretest instruments. The Media of  board games have been declared valid from the aspect of material experts with a score of 95% and valid from media experts with a score of 96%, both of which are very good categories. The results of practicality assessment get a score of 90% in the very good category. The results of the pair t-test data that show the sig value. (2-tailed) produced from the pretest and posttest data is written 0,000 which means that the significance value is close to zero which is less than 0.05 with the posttest average value (67) higher than the average pretest (50.5). So that the media is effective to be used as a means of training Algebra questions at the junior high school level.

Abstract

The problems in learning mathematics, especially comparative material, have not combined with religious theory in the learning process. The merging of Knowledge , especially mathematics with the knowledge  of religion is very important, because in addition to getting mathematics, the student will directly learn about the knowledge  of religion. The comparative learning using the Nisab Zakat theory will encourage  to bring out reasoning abilities and students think creatively, and innovative in solving the problem. The aims of the research is to find out how the influence of applying of HLT toward the student's reasoning on the third semester of Education of elementary teacher department  in STKIP Muhammadiyah Bangka Belitung. The research method of this research is quasi-experimental design. Data collection techniques are tests with hypothesis testing using t-test statistical formula. The average value of pretest before HLT applied in learning is 64.7 with a minimum value of 49, and a maximum value of 75.8. While the value on the post-test after being applied to HLT obtained an average value of 86.4 with the minimum value of 67 and the maximum value of 100. Then with this it can be concluded that there is a positive effect of the application of HLT (Hypothetical Learning Trajectory) comparison material using the Nisab zakat theory on results Student learning mathematics comparison material.

Abstract

Geometry transformation is one of the mathematics learning materials that are very closely related to everyday life but has many formulas that make it difficult for students, especially high school students to understand it. Seeing the importance of geometric transformation and difficulties experienced by students, the development of a geometry transformation module was carried out which was able to eliminate difficulties in studying and understanding the geometric transformation. This research is development research with ADDIE development modelto produce a valid, practical, and effectivemodule on geometric transformation. The module is aimed at helping high school students to understand the relevance of geometry transformation to reality and how to solve it. This module is declared valid in terms of media and material aspects with an average validity score of 3.7 (valid) for material aspects and 4 (valid) for media aspect. This module was tested on 10 ten grade high school students and is declared practical based on the indicators of the media practicality sheet. In addition, with the help of a test sheet, it can be seen that this module is able to improve learning outcomes. This can be seen from the results of a paired simple test which shows a significance value of 0,000 () which means that this module is able to provide differences or improve students’ learning outcomes based on the average pretest score which is 51 to 88 of theaverage posttest score. Based on the three tests, this module was declared valid, practical, and effective to be used in geometric transformation material for high school students.

Abstract

Pre-service teachers need to know the variety of learning methods and they should have the ability to plan learning strategies as well. This study aims to develop a module of mathematics learning strategy based on the review of articles published from 2014–2018. This study was conducted using Borg & Gall development model and the quality criteria used referred to Nieveen (valid, practical, and effective). The result shows that the module has met the validity criteria of 3.4, practical criteria of 82%, and it also has fulfilled the criteria of effectiveness. This module is recommended as a reference to study about recent mathematics learning strategy. A further study is needed to develop such a module based on international journals.

Abstract

The low learning outcomes of mathematics are not appropriate thought of learning models in the classroom. Therefore, the NHT and TPS learning models can be applied to improve the learning of outcomes of the student. This study aims to determine the differences in learning outcomes using the NHT learning model with the TPS learning model. The sampling technique is used as a random sampling cluster with 2 groups of experiments for the first experimental group  (classroom view of TPS model) and the second experimental group (classes of NHT modeling). The instrument of this research uses the test of mathematics learning result. The hypothesis test is used  T-Test. The conclusion of research that are differences in the outcomes of the two learning models (NHT and TPS) on learning outcomes, based on the marginal mean of the TPS learning model is better learning outcomes than the NHT learning model.

Abstract

This research aims to describe the creative thinking process of students based on Wallas theory in solving mathematical problems. This type of research is qualitative research using qualitative descriptive methods. This research will begin by determining the type of Adversity Quotient using the Adversity Response Profile (ARP) test. The sampling technique is used positive sampling, selected 2 subjects to represent the climber type . The Data collection techniques are used written tests and interviews then analyzing the result based on indicators that fulfill Wallas creative thinking process and its level. The data analysis technique used is according to Milles and Huberman and the data validity technique uses technical triangulation Based on the results of data analysis, it was found that climber 1 is the climber with the creative thinking level that is very creative, Climber 1 is able to fulfill all stages of the creative thinking process by Wallas and its complete characteristics include fluency, flexibility, originality, elaboration. Whereas Climber2 is a climber with creative thinking level that is creative, Climber 2 is able to fulfill all stages of the creative thinking process by Wallas but incomplete on its characteristics.

The aim of the research  to know the level of student  problem solving skill of  Senior high school students on their  mathematical problem and activity concentration. The object of the research was conducted  at one of Senior high school of Cimahi. the Subject  of the research  is all  twelve grades of Senior high School Students of Science Program in Cimahi. The research used descriptive qualitative research to describe the student analysis error on doing the question of problem solving ability. The data of the research was found using diagnostic of series and rows and also student questionnaire. Data collecting technique used Miles and Huberman concept  that are reduction data, reporting data and draw the conclusion. The result of the research are: (1) the level of the ability to solve the problem is still low (2) the common student error did not understand the questions and have no ability to communicate in mathematical form. (3) the student’s activity is rated strong. Some solutions can be given to increase student problem solving ability through practice or question drill structured  and gived the variety questions as material practice.
