Based on the questionnaire to 52 students UNNES Department of Chemistry Faculty, teaching methods of lectures and lecturers are still such things are very boring for students. Moreover, the course material is primarily Basic Chemistry subjects that are less desirable and considered difficult by students because it is abstract, so it needs to be assisted visualization. It is therefore interesting to study as well as creativity and innovation fostering student learning and not so monotonous. The purpose of this study to determine the increase in the chemical and life skill learning of students with learning models CEP. This research is a class action that was implemented in three cycles. Each cycle consists of planning, implementation, observation, and reflection. The subjects of this study were students of Chemistry Department of Education UNNES the second half. The focus is investigated in this study is the result of learning and life skill development of students. The data obtained and analyzed using descriptive methods to determine the increase in the learning and life skill development of students. From the research, studying classical completeness increased from cycle I (44%), cycle II (82%), and cycle III (87%). The average scores of students cycle life skill I, II, and III, respectively 77%, 80% and 92% .. Based on these results we can conclude that the results of student learning and life skill can be improved through the implementation of CEP learning model.

Mata pelajaran kimia khususnya materi larutan elektrolit dan non-elektrolit merupakan mata pelajaran yang membutuhkan pemahaman konsep. Kurangnya pemahaman konsep dikarenakan guru kurang memahami gaya belajar yang dimiliki siswa. Untuk itu dibutuhkan suatu model pembelajaran yang sesuai dengan gaya belajar siswa agar materi tersebut dapat dipahami. Model pembelajaran tersebut yaitu model pembelajaran VAK menggunakan media Swishmax. Penelitian ini bertujuan untuk mengetahui pengaruh dan berapa besar pengaruh model pembelajaran VAK menggunakan media Swishmax terhadap hasil belajar siswa. Populasi dalam penelitian ini siswa kelas X SMA Negeri 1 Pemalang tahun pelajaran 2011/2012. Teknik penentuan sampel dengan sistem Cluster random sampling diperoleh dua kelas untuk dijadikan sampel yaitu kelas X3 sebagai kelas eksperimen yang mendapat perlakuan menggunakan model pembelajaran VAK menggunakan media Swishmaxdan kelas X2 sebagai kelas kontrol yang mendapatkan perlakuan pembelajaran ceramah diskusi. Data penelitian diperoleh dengan metode dokumentasi, tes, angket, dan observasi. Simpulan penelitian ini menyatakan bahwa model pembelajaran VAK menggunakan media Swishmax mempengaruhi hasil belajar siswa. Besarnya pengaruh yang diberikan model pembelajaran ini yaitu 35,13%.

MAN has conducted research in Bradford 1 aims to find and how much influence the application of Active Learning SAVI based on the results of class X studying chemical redox subject matter. The study population numbered ten in class X class. This experimental method with random sampling cluster sampling, obtained by X-6 class of experiments are given in the class-based learning Active Learning SAVI, and the class of X-8 in a conventional classroom learning is given control. Two kinds of methods of data analysis, the preliminary data analysis including test for normality and homogeneity test results of eight classes normally distributed and homogeneous. Final data analysis also includes the results of normality test normal distribution of data, test the equality of two variances of two groups of results have the same variance of 1.1311. Hypothesis test is obtained by analysis of biserial correlation coefficient of 0.5269, the coefficient of determination of 27.76%, thoroughness studied in the classical style in the experimental class at 92.6%, while the control class by 76%. The average total score of affective and psychomotor aspects, experimental class achieved better grades than the control class. Based on opinion poll of students gained an average of students strongly agreed with the application of Active Learning teaching methods based on students' Savi. Therefore, the experimental class students learn better than the control class.
