Developing Construct 2 Android-Based Education Math Game to Improve the ICT Literacy on Number Patterns Subject

This research aimed to describe the development process and results of the Construct 2 Android-based education math game on number pattern subjects to increase student's ICT literacy. This research employed the Research and Development method with a 4-D development model. The development model consisted of 4 stages: the Define stage, the Design stage, the Development stage, and the dissemination stage. Also, the researchers developed the Android-based application based on ICT literacy indicators. The application must be valid, practical, and effective. The results showed a correlation coefficient value of 0.87 and included in the valid category with very high interpretation. The level of practicality of the developed product was 83.96% based on a users' responses questionnaire. The effectiveness was determined based on the percentage of students' learning outcomes which was 83.33%. The increase in students' ICT literacy was determined based on the ICT literacy questionnaire and learning outcome tests' average N-Gain score. The average N-Gain value obtained was 0.75, with an average value for the ICT literacy questionnaire of 0.89 and the average value for the learning outcome test of 0.61. Based on these three criteria, it can be concluded that the Construct 2 android-based educational math game on the number pattern material can improve students' ICT literacy.

Abstract. The rainbow connection of the graph of G = (V, E) if for each pair of points u and v in G there is a path with points u and v as the end points on each side obtaining different colors, the path is called the rainbow path. The rainbow-connected number graph G is the smallest positive integer such that G has a rainbow connection staining denoted rc(G). While the graph is said to be a rainbow 2-connected staining on G if for each pair of points u and v on the sides there are 2 different paths, with u and v being the end points of each side obtaining different colors and 2 passages can not intersect each other, denoted rc2 (G). Let G be the graph connected with  so that , with d is degrees. Let G be a rainbow   so that where κ is the number of paths of rainbow connecting every two distinct points in G. The results of this research are new theorem about the rainbow connection and 2-rainbow connected.   Keywords : rainbow connection, 2-rainbow connected, rainbow pat

Student Critical thinking in Solving Two Dimensional Armetics Problems Based on 21th Century Skills

Critical thinking has a very important role in constructing the improvement of students\u27 ability to face the 21st century, especially in generalizing the pattern of the two dimensional arithmetic series. Since critical thinking is necessary when we try to understand and process information, put forward ideas or ideas objectively, and develop deeper insights. The purpose of this study is to analyse students\u27 critical thinking skills based on P21. This study is a combination method in which this method is a combination of quantitative and qualitative methods. Research subjects are high school students. This subject is expected to provide an overview of critical thinking based on P21. Data collection techniques in this study are: (1) test, this technique is used to measure the ability of students in mastering the arithmetic array of two dimensions; (2) interview; it is based on the students work in solving the problem of two dimensional arithmetic series. The data result showed that in the experimental class had increased 40.85% on the indicator of effective reasoning, 37,44% on indicator of thinking system, 47,53% on decision indicator, and 42,55% on problem solving indicator. While the control class experienced a 19.5% increase in the effective reasoning indicator, 0.07% on the indicator of the thinking system, 0.02% on the decision making indicator, and 0.02% on the problem solving indicator

Algebraic Learning through Caring Community Based On Lesson Study for Learning Community

Algebraic material is still considered difficult by many students, especially for those in junior high schools. They still find it difficult to understand and solve algebraiv problems. This happens because their level of understanding for algebraic material is still low, therefore it takes the participation of many parties, including peers and parents, to overcome this problem (caring community based learning). This study aims to improve the students’ understanding of the algebraic concept and to minimize the errors that occur in solving algebra problems. The study was conducted in 3 cycles, each cycle consisted of 3 phases, ie plan - do - see, in accordance with the learning cycle in the lesson study. The subjects of this research were 32 students of VII G class of MTs Negeri 2 Jember in the 2017/2018 academic year. Data collection techniques used were observation, tests and documentation. The data were analyzed using descriptive qualitative method through three steps: data reduction, data presentation and conclusion. The results showed that there was a high confidence increase in learning among the students and the “care” occured in the learning process. The students’ understanding and mastery of algebraic material were also improved through caring community based lesson study for learning community
