This research was purpose to find out the effect of Numbered Heads Together model toward problem solving ability of thematic integrative learning of IV SD Negeri 3 Krapyak Jepara. This research using experiment method type quantitative research with research design Pretest Posttest Control Group Design. The population in this research is graders IV SD Negeri 3 Krapyak Jepara which amount 48 students. Retrieval sample used Probability Sampling Technique type Simple Random Sampling. By virtue of one sample t test, providable tcount > ttable (10,371 > 1,714) so Ha accepted, its mean problem solving ability of the student that given Numbered Heads Together model over 65, from calculation of the test to test with two sample t test, providable tcount = 9,052. Because ?óÔé¼ÔÇ£ 2,01< 9,052 > 2,01 so Ha accepted, its mean problem solving ability of the student that given Numbered Heads Together model better than student who was given the conventional model and the result of double correlation test calculation result Ryx1x2 = 0,946 then testing its significance using F test with the result Fcount> Ftable(89,5 > 3,47) so the coefficient of double correlation that found is significant. Its mean there is a strong correlation between cooperation and braveness toward problem solving ability. Thus, it can be concluded that the Numbered Heads Together model having an affect on problem solving ability of?é?á the student in thematic integrative class IV SD Negeri 3 Krapyak Jepara.

The purpose of this study was to obtain empirical evidence about the use of cooperative models of Team Games Tournament to increase the ability of students on solving problems with the summation material fractions. To achieve these objectives, the research carried out in the form of an experiment by comparing the problem solving ability of students to the material sum of fractions through the use cooperative model of TGT and students who received conventional learning. The design is a pretest-posttest control group design. The sampling technique used is purposive sampling technique. The instrument used is to use tests that pretest and posttest. The data were analyzed quantitatively for the results of the pretest, posttest, and normalized gain value. Based on data analysis in this study we concluded that there are differences in problem solving ability of students to the material sum of fractions through the use of cooperative models of Team Games Tournament with students who studied with conventional models, and improved problem solving abilities of students in the material that follows the fractional summation cooperative learning of TGT better than students who take the conventional learning model. Therefore, the ability of solving problems of students at grade material fractions summation cooperative modeled of TGT has increased quite good.

SMA 5 and SMA 21 are the leading schools in Makassar City which have a Youth Counseling Information Center. Previous research looked at the influence of game simulation and brainstorming on the knowledge and attitudes of stundent about reproductive health for high school adolescents in Makassar City, including SMA 5 and SMA 21, but the results did not have effect on students' knowledge and attitudes. Therefore, the researcher took the initiative to provide another intervention in the form of counseling. This study aims to determine the effect of counseling on knowledge and attitudes about risky sexual behavior among students in SMA 5 and SMA 21 Makassar City. This study used a quasi-experimental design with a randomized pre test post test control group design. A sample of 76 students of class XI SMA 5 and SMA 21 Makassar City, using simple random sampling technique. Data collection was using a questionnaire. Statistical analysis used paired t-test and independent samples t-test. The results showed that there was an effect of counseling on knowledge (p = 0.002) but there was no effect on attitudes (p = 0.865) in SMA 5 and SMA 21 Makassar City. It is suggested that SMA 5 and SMA 21 Makassar City be active in conducting counseling, especially counseling about attitudes, so that students have positive attitudes about risky sexual behavior.

2Department of Midwifery, Poltekkes Kemenkes Surabaya, Indonesia; [email protected] ABSTRACT One of the efforts made to improve the knowledge, skills and competence of midwives is the Midwifery Update training. This study aims to determine the effectiveness of midwifery update training on increasing knowledge of midwives in midwifery services. The study design was a post-test only control group design. The population consisted of an experimental group of 41 people and a control group of 41 people. The experimental group had the midwifery update training in 2019, while the control group was midwives who had never attended midwifery update training in 2019. The experimental group and the control group were selected by using cluster sampling technique after that the sample selection used simple random sampling. Data analysis was used independent samples t -test. The mean knowledge results of the midwifery update group that had never attended midwifery update training was 55.11, while the mean knowledge results of the midwifery update group knowledge was 75.19. Based on the independent t-test, it was found that the t-count results were -8,987 with a p-value of 0.000 (

This study began with many students having low concept comprehension skills. This can be seen from the learning process that there are still many students who are less active, and there are still many students who still get grades below the KKM. the purpose of this study was to determine the ability to understand students 'mathematical concepts using the Think Talk Write learning model better than students' ability to understand mathematical concepts using conventional learning models in class VIII MTs Al-Ihsan. The type of this research is experimental, the design is Quasi Experimental, with Randomized Subjects Posstest Only Control Group Design. The sampling technique in this study is cluster random sampling, where class VIII.3 was chosen as the experimental class and class VIII.5 as the control class. Data collection techniques through concept understanding tests, then data analysis techniques used are inferential statistical analysis using the "t" test (Independent Sample t Test). Based on the results of research testing the hypothesis of this study obtained t count = 2.061 t table = -1.999. This means that the ability to understand mathematical concepts of students using Think Talk Write learning models is better than the ability to understand mathematical concepts of students using conventional learning models in class VIII MTs Al-Ihsan

This study aims to determine the effect of group investigation (GI) learning model with brainstorming technique on student physics learning outcomes (PLO) compared to jigsaw learning model with brainstroming technique. The learning outcome in this research are the results of learning in the cognitive domain. The method used in this research is experiment with Randomised Postest Only Control Group Design. Population in this research is all students of class XI IPA SMA Negeri 9 Kupang year lesson 2015/2016. The selected sample are 40 students of class XI IPA 1 as the experimental class and 38 students of class XI IPA 2 as the control class using simple random sampling technique. The instrument used is 13 items description test. The first hypothesis was tested by using two tailed t-test. From that, it is obtained that H0 rejected which means there are differences of students physics learning outcome. The second hypothesis was tested using one tailed t-test. It is obtained that H0 rejected which means the students PLO in experiment class were higher than control class. Based on the results of this study, researchers recommend the use of GI learning models with brainstorming techniques to improve PLO, especially in the cognitive domain.

This type of research is Quasi Experimental Type Nonequivalent Control Group Design. The sampling technique used simple random sampling technique with the results of several considerations. The instrument used is a test that is a description test. Data analysis techniques in this study used a prerequisite test in the form of normality and homogeneity tests and hypothesis testing using the t-test. The results showed that there was a significant influence in the use of the problem solving model method on the learning outcomes of the story about the flat-building area of class V SD Cluster 1 North Pariaman. This is evidenced by the results of the t-test with a significance level of 5% obtained tcount = 3.71 &gt; ttable = 1.72. Mathematics learning outcomes obtained by the experimental group were higher than in the control group, indicated by the control group mean = 73.09 and the mean obtained by the experimental group = 87.18.
