Abstract : This research aimed to develop computer-based mathematics learning media model are valid to help students to understand the topic of rectangular.This research and development use development model by Borg and Gall modified by Sugiyono. The steps of this research and development Â are find the potentials and problems that must to do analyzed first. And then, find the informations by study of literature. Product designÂ is through two stages,Â that are make paper based design first and then computer based. The programs that used for product design of computer based are program frontpage, microsoft power point and photoshop. Learning media is validated by three experts or validators and further revised based on the input from validators. The revised learning media is tested on two stages, that are a small group consist of five students of class VII and a large group consist of forty students from SMPN 4 Pekanbaru. Based on the analysis of data and discussion can be concluded that computer-based mathematics learning media is already valid with an average value of 3.17 by materials validator and 3.18 by media validator. This computer-based mathematics learning media is also already qualified practicalities with an average of 97,92% on a small test group and 99,22% in the large group test.Â Key Words : Computer-based Learning Media, Development, Rectangular

Abstract: This research is a developmental research which aims to produce computer-based learning media interactive tutorial model on the subject circle for class VIII SMP/ MTs that is valid and practical. This developmental research used development model based on the teory of Borg and Gall. The stages are: (1) potential and problem; (2) literature collection; (3) product design; (4) product validation; (5) product revision; (6) product tested; (7) product revision; (8) product tested in large group; (9) product revision. In the first stages, the researcher analyzed potentials and problems. After that, the researcher collected the reference materials, then designed the product and put it into a computer. The learning media that had been developed was be evaluated by three validators based on the aspects of learning, display, program and curriculum, and revised according to the advice of the validator. Next, the learning media that had been revised was be tested in two stages: product testing in small groups with the subject of five students of class VIII SMP Juara Pekanbaru and product testing in large groups with the subject of 25 students class VIII SMP Juara Pekanbaru. Based on the results of data analysis and discussion, it can be concluded that the computer-based learning media interactive tutorial model for the subject circle class VIII SMP / MTs assessed valid by experts with an average value of 3.59 and received a very good response from students of class VIIIKeywords: Computer-based Learning Media, Research and Development, Circle

Abstract : The aim of this research is to develop interactive computer-based tutorial for mathematics class VII topics of lines and angles. This research use development model by Borg and Gall modified by Sugiyono (2011). Development is done through the following steps: (1) potentials and problems; (2) data collection; (3) media design; (4) validation; (5) revision; (6) small group test; (7) revision; (8) large group test; and (9) revision. At the stage of potentials and problems, researchers created a needs analysis of the results of interviews with teachers of Mathematics. Based on the needs analysis, learning media developed for six class meetings. Learning media is validated by three experts and further revised based on the input from validators. The revised learning media was tested on a small group consist of five students of class VII. The learning media was revised and test in large group involved 21 students of class VII SMP N 1 Rengat. From the large group test results, the learning device improved.

AbstractThe ability to think mathematically creative is one of the competency standards for graduate students at the vocational level. Based on the results of previous studies said that the mathematical creative thinking ability of vocational students is very low and the interview of researchers in several mathematics teachers in Pekanbaru vocational school said that Pekanbaru vocational students were accustomed to mathematical problems according to the teacher's example and it was recognized that teachers lacked daily problems. This study aims to determine the mathematical creative thinking ability of vocational students in Pekanbaru City in row and series material. This type of research is a qualitative descriptive study. The instrument used was a mathematical creative thinking ability test with 4 indicators namely fluency, flexibility, originality and elaboration. Questions in the form of a breakdown test were taken from the SMK National Exam question bank and given to 36 students of class X TKJ-2 SMKN 2 Pekanbaru. From the test results it can be concluded that the percentage of mathematical creative thinking ability of SMKN 2 students is at the ability to think creatively enough at 42%. Where the fluency indicator is 56%, the indicator of Authenticity (originality) is 38%, the Elaboration indicator is 46% and the indicator of Flexibility is 28%.Kata Kunci : Kemampuan Berpikir kreatif Matematis, Barisan dan Deret
