Abstract

The low learning outcomes of the students is because in the learning process of teacher and student interaction only goes one way. Teachers often use lecture methods so that students tend to only accept what is given. This can make the students' motivation and activeness in following the lesson to be low. Therefore, researchers try to vary the cooperative learning model using Chemopoly Game media and Tournament Question Cards. This is quasi experimental research with population class X MIPA in SMAN 2 Kota Bengkulu and sample is class X MIPA C using media Tournament Question Cards and class X MIPA D using Chemopoly Game media. Data analysis used were mean score, normality test, homogeneity test, and t test. The average posttest grade of experiment I is 85,59 While for experiment class II is 79,38. Then t test and obtained tcount> ttable (2.62> 2.38). The results of this study indicate that there is a significant difference between student learning outcomes using Chemopoly Game media and Tournament Question Cards on basic chemical law materials.

Abstract

The average students' chemical learning outcomes are still low, the low learning outcome is influenced by several factors, including students still consider that chemistry as one of the scary, difficult to understand and less interesting lessons. Therefore, the research wants to vary the learning process in the classroom by applying the learning model of Discovery Learning with Group Investigation model. This research was aimed to find out the students’ achievement differences of chemical subject by using Discovery learning and  Group Investigation model. The research is quasi experimental research. The population of this research were class X MIPA in SMAN 9 Bengkulu City, and the sample were X MIPA 2 and MIPA 3. This research using two experimental classes, that is class X MIPA 2 applying Group Investigation model and X MIPA 3 applying Discovery Learning model. Analysis of the data used is mean values, normality test, homogeneity test, and t-test. Post-test mean values for first experiment class is 78,12, but for second experiment class is 81,3. To determine whether the differences of student’s learning outcomes between both of experiment classes or not, we use t-test by using the differences between student’s pretest and posttest values, tcount > ttable (2,17 > 1,67). The result of this research showed that Ha accepted, in other words is a significant differences in learning outcomes of student’s applying Discovery Learning and Group Investigation model.

Abstract

The problem of learning process that often occur in classroom that the use of conventional learning method. This makes the lack of student activeness in the process and makes the students' low learning outcomes . So that researchers interested in finding variations of teaching by combining the learning model with instructional media. The use of this media is taken into consideration from its practicality, strength, and effectiveness. The type of research used is quasi experimental research with population class XI IPA in SMAN 8 Bengkulu  and sample is class XI IPA 2 and class XI IPA 3. The sample in this research is by applying smart card media for experiment class 1 (XI IPA 3) With the experimental class 2 (XI IPA 2) using smart steering card media on salt hydrolysis topics. Data analysis used are mean value, homogeneity test, normality test, t test and questionnaire analysis. The average value of posttest experiment class I is 76.875, while for experimental class II is 80,85. Then t test with significant level (? = 0,01), then got tcount value equal to 5,41 and 2,39 for table . The results showed that there were significant differences in learning outcomes between the smart card media class and the smart media grade of the steering wheel on the salt hydrolysis topics.

Abstract

The purpose of this research is to know the difference of students' chemistry learning result between experiment 1 class which applied learning cycle model (5E) with experiment 2 class that apply two stay two stray learning model on acid acid base material in class XI IPA in SMA Plus Negeri 7 Bengkulu City. Research conducted is a research with the type of quasi experiment. Chemical learning result data obtained from pretest value and posttest value where the average value of improvement of cognitive learning result for experiment class 1 is 47,78. And the average value of cognitive learning improvement for experiment class 2 is 54.875. With  testing the hypothesis using t test with significant level (? = 0,01), then got value for titung equal to 2,60 and for ttable got value equal to 2,380. The results showed that there were significant differences in learning outcomes between classes that applied learning cycle model (5E) with classes that applied the two stay two stray learning model.
