Abstract

The problem that underlies this research is the lack of collaboration and mathematics learning outcomes of students of class IX C of SMP N 4 Sumbang. This can be seen if students have difficulty in understanding the material, students tend to be quiet and do not want to cooperate with friends, even though the cooperation of students is very necessary to achieve the success of teaching and learning. To create student cooperation in the learning process, a learning model is needed. One such learning model is the TAI (Teams Assisted Individualization) type of cooperative learning model, where the model is oriented towards collaboration, both mentally, attitudes, and socially. The purpose of this research is to find out the improvement of cooperation and learning outcomes in mathematics through the application of cooperative learning models in the form of sequence and series TAI material. This research is a Classroom Action Research. Learning tools, namely syllabus, lesson plans, teaching materials, and worksheets. While the research instrument is the description test and observation sheet. The subjects of the study were 22 students of the IXC class at SMPN 4 Sumbang. Data sources come from teachers and students. Data collection techniques are by observation, and tests. The study was conducted in December 2017 until April 2018. The subject and time of the study were chosen because the researcher taught in the class and the implementation time was adjusted to the lesson schedule. The research procedure begins with problem identification, action planning, implementation of actions and observations, and analysis and reflection. The results showed that the ability of student cooperation, from the first cycle the percentage of student cooperation with the category of "quite good" 27% and the category of "good" by 73% to the category of "good" 54% and the category of "very good" by 45% in the second cycle. Student learning outcomes in the first cycle obtained an average of 72.18 with a classical completeness of 59.09% and an increase in the second cycle an average value of 80.36 with a classical completeness of 81.82%. From these results it is recommended that teachers be able to clarify the process of assessing the ability of students to collaborate in the learning process, so that the implementation of learning can run smoothly. While students are advised to increase collaboration so that individual and group learning outcomes can be achieved to the maximum.

Abstract

The development of science and technology rapidly growth in use right now, learning device which used inadequate so that the knowledge of students about the technology lagged and limited learning devices used in school. Devices learning of mathematics are effective and in accordance with the subject matter has not developed as expected, and development in the field of education is very important to improve the quality and the quality of resources man. This suggests that education should be made a major priority by both Governments, the education community and Manager. Improve the quality of education endeavors to improve the quality of human resources. This gave the impetus for the Government to always trying to fix and improve the quality of education at every level of education. Technological developments in recent decades go very quickly in line with the development of technology, including computer networks. Various supporting technologies and applications have also been developed in an effort to support and facilitate the activities of human life and organization, including teaching and learning activities in the world of education. In General, the device is software to deliver information or messages from one place to another. The device used in the learning process, including teaching and learning activities.

Abstract

The ability of mathematical connection is an important thing to be trained to students. Initial observation when this research was conducted showed that there were problems of mathematics learning in SMA Al-Muqoddasah of Ponorogo, that is, the tendency of teacher centered learning activities and low learning result of mathematics students especially in relation between some concepts in mathematics. Reciprocal Teaching Strategy is one of the alternatives that can be done to help students connect some concepts in learning mathematics, and enable students so that they can think creatively and critically. The purpose of this study is to describe the learning with Reciprocal Teaching strategy that can improve students' mathematical connection ability in SMA Al-Muqoddasah of Ponorogo.

Abstract

Students' Achievement Index (IP) changes each semester, both increase and decrease. This affects the GPA obtained by graduation. IP obtained by students in even semester is only influenced by IP in odd semester. Based on nature of Markov Chain, if there are past and future events, then future events are independent of past events and only tied to current events. Markov chain is used to analyze probability of IP change each semester and to predict the predicate of graduation with state space used, namely: satisfactory predicate with GPA of 2.00 - 2.75 to state 0, satisfactory predicate with GPA of 2.76 - 3, 24 becomes state 1, predicate is very satisfactory with GPA of 3.25 - 3.79 being state 2, and cumlaude predicate with GPA of 3.80 - 4.00 being state 3. This study aims to predict the predicate of student graduation and to analyze factors that have significant effect on IP. Dummy regression is used to analyze factors that have significant effect on IP with the factors studied, namely: campus facilities and infrastructure, friendship, organizational activeness, internet use, and money. Results showed that predicate of graduation with satisfactory predicate, GPA range of 2.00-2.75 was 0.56%, students who graduated with satisfactory predicate GPA range 2.76-3.24 was 7.39%, students who graduated with very satisfactory predicate, GPA ranges 3.25-3.79 was 54.18%, and students who graduated with cumlaude predicate ranged from GPA 3.80-4.00 was 37.87%. Factors that have significant effect on student GPA are activeness in the organization and use of the internet.

Abstract

Difficulties experienced by students to learn mathematics caused by the lack of practical and less interesting media used by lecturers in learning mathematics has an impact on the low student learning outcomes, especially in the matter of relations and functions. Therefore, “this study aims to determine the feasibility and response of students to the design of mathematics e-module learning devices using sigil software. This type of research is Research & Development (R&D) using the ADDIE model. Data collection techniques using interview techniques, questionnaires and tests. Validation was carried out by three material experts and two media experts. The validation results show that the e-module is suitable for use because it is good in terms of content, language, and presentation feasibility. The revised E-Module was tested on a small scale test (10 students) and continued with a large scale test (28 students). Student responses to e-modules also scored high on all indicators. It can be concluded, the e-module that has been developed is feasible and effective for use in the mathematics” learning process.
