This study aims to assess the effect of cooperatife learning model type group investigation on introduction manajement education course to increase students’ creativity of students PGSD semester I UM Surabaya in academic year 2016/2017. This research use quantitative approach based on the test score of creativity or creative thinking ability of students. The indicators of creativity consists of fluent, flexible, and original thinking in which the score or value totaled and analyzed by using t-test two independent samples. On the validity of the test, it is obtained that the counting of  ≥ r r-critical (0.334), which is item 1= 0.937 and item 2 = 0.885 then the instrument is said to be valid and can be used. In the test of reliableility, the counting of r > r critical (0.60), namely Alpha value of 0.781 means greater than 0.60. Thus the entire item instrument is reliable. The results of hypothesis testing can be seen from the data that has been analyzed by t 5.222> t-table 2.00 (α = 0.05). it can be concluded that the problability of error in this research still below 0,05. Hypothesis testingbcan be decided that with the high price of 5.564 t-test has a significant level of 0.000 which turned the position which is still far below the value of α = 0.05. Therefore, this research successfully rejects the significant level of 5%. Furthermore, it can be concluded that  was proved right. Mean posttest in the experimental group was 85.63. The mean post-test control group was 75.45. It can be concluded that the creativity or creative thinking ability of students in the experimental group was higher than the control group. It is mean that model of cooperative learning type group investigation positive effect on creativity or creative thinking students’ ability.

This research aims to know the effect of using virtual laboratorial towards concept mastery and creative thinking ability of students on the material of vibrations and waves. This research is an experimental research that uses pretest-postest control group design. The population of this research is all grade VIII students of SMPN 1 Alas Barat in the academic year 2013/2014 and the sample of this research is grade VIII3 as experimental group and VIII4 as control group that determined by cluster random sampling technique. The instrument thet used to collect the data is test that made in terms of multiple choices and essay test. The data is analysed by statistical formula of N-Gain and t-test. The result of N-Gain of experimental group concepts mastery is 0,5% and control group is 0,2%. Meanwhile, the result of N-Gain of experimental group creative thinking ability is 0,3% and control group is 0,1%. The resultof t-test shows that tobtined of concepts mastery is 1,877 ≥ ttable is 1,671. Whereas, for creative thinking ability shows that tobtined is 1,998 ≥ ttable is 1,671. It means that there is a difference of concept mastery and creative thinking ability of students on the material of vibrations and waves. Therefore, it can be concluded that the use of virtual laboratorial has an effect towards concept mastery and creative thinking ability of students on the material of vibrations and waves.

This study was a pre test-post test experiment without control group design having a goal to examine the role of Prior Mathematics Ability (PMA), Sylver  approach (SA) toward student’s mathematical creative thinking ability (MCTA) and Self Regulated Learning (SRL).  The study involved  65 eleven  grade student, a PMA test, a MCTA test, and SRL scale. The study found that PMA and SA took good role on obtaining student’s MCTA, its N<Gain> and SRL. On student’s MCTA, and its N<Gain> students getting treatment with SA attained better grades than that of students taught by conventional teaching, and the  grades were still at medium level.  On SRL,  there was no different grades between students on both teaching approaches, and those grades were at fairly good  level.  The other findings, there was no association between MCTA and SRL, and students performed high perception toward SA.

This is an experimental research by using experimental group and control group. The research design was Post-test Only Control Group Design. The population of this research was the students of class VII SMPN 1 Lembar academic year 2015/2016. The sampling technique was Cluster Random Sampling in which class VII 2 as the control group and class VII 3 as the experimental group. Both of the groups were given a pre-test before the treatment to know the homogeneity of the groups. The instrument used is an objective test in form of multiple choices. The finding showed that the mean of the posttest in experimental group was 70 and the control group was 60.67, in which both of them were distributed normal and homogeneous. The post-test result was analyzed by using t-test (t-test polled variants) in which the value of the was 2.473 and the  was 2.015 with dk=46 and the significant level was 5%. It showed that the was accepted and was rejected. Therefore, it can be concluded that Predict Observe Explain (POE) Method gave significant effect to the students’ achievement in Physics at Class VII SMPN 1 Lembar Academic year 2015/2016.

This study deals with the effect of POW+TREE Strategy on students’ ability inwriting hortatory exposition text.. The problem of the study is to find out whetherPOW+TREE Strategy significantly affects students’ ability in writing hortatoryexposition text or not. This study was conducted by using experimental design.The population of the study was the students of eleventh grade of SMA Methodist8 Medan in the academic year 2015/2016, there were 3 parallel classes of gradeXI. There were two classes selected to be sample. The Experimental group (XIIPA-2) was taught by applying POW+TREE Strategy, while the Control group(XI IPA-3) was taught by applying conventional strategy. The data of the studywas obtained from the students’ scores of writing test. There were two kinds oftest used in this study. They were pre-test and post-test. The data were analyzedby applying t-test formula. After analyzing the data, the result of the study showedthat t-observed (2.338) was higher than t-table (1.994) (t-observed > t-table) at thelevel of significance of p=0.05 and the degree of freedom (df) = 68. It can beconcluded that applying POW+TREE strategy significantly affects students’ability in writing hortatory exposition text, or in other words, the null hypothesisis rejected , therefore the alternative hypothesis is accepted.

This study aims to determine the influence and the effect size of student facilitator and explaining learning model, assisted by non-projection visual media toward the science knowledge competences of fourth grade students at SD Gugus Letda Made Putra North Denpasar 2017/2018 academic year. The type of this research is quasi experimental with non-equivalent control group design. The population of this research was 11 group classes of fourth grade students at SD Gugus Letda Made Putra North Denpasar which amount to 393 students. The sampling technique used in this research is the group sample technique. The sample of this study was consist of 2 groups; experimental group and control group. Each group was given a pre-test and then measured by using the t-test to determine its equality. The data of science knowledge competences were obtained through a test of multiple choice questions. After obtaining the post-test data of science knowledge competences, the data were analyzed by using t-test with polled variance formula. The average post-test score of the students in the experimental group is 75,37 and the average student in the control group is 68,25. Based on the 5% of significance level and the dk = 71, the result obtains the tcount = 2,147 > ttable = 1,994. Thus, there is a significant difference of science knowledge competences between the experimental group and the control group. It can be concluded that student facilitator and explaining learning model assisted by non-projection visual media has a significant influence toward science knowledge competences of fourth grade students at SD Gugus Letda Made Putra Nort Denpasar 2017/2018 academic year. The calculation of the effect size model to science knowledge competences is done by calculating the Cohen's d Coefficient, which obtains value d = 0,51 with medium effect category.
