This research is an experimental research type with the static group pretest-posttest desaign design. The sample in this study were students of class VIII SMPN 21 Mataram. The sampling technique in this research is purposive sampling with circle material. The research data collection process used interview, observation, and test instruments. From the research results, the participatory model of learning outcomes obtained an average pretest score of 58.68 and an average posttest score of 73.32. While the discovery learning model of learning outcomes obtained an average pretest score of 58.86 and an average posttest score of 73.91. The results of the hypothesis test of learning outcomes found that the sig. (2-tailed) 0.821. Because the sig value> 0.05, meaning that H0 is accepted and H1 is rejected, it can be concluded that there is no significant difference in effectiveness between the participatory model and the discovery learning model on the mathematics learning outcomes of grade VIII students of SMPN 21 Mataram

This study was a quasi-experiment research with pretest-posttest control group design. Population in this study were students of class XI IPA at SMAN 6 Palu enrolled in the academic year of 2015-2016 amounting to 43 student. Sampling technique was a sampling saturated. Samples in this study were 21 students in the class XI IPA2 as the experimental class, and 22 students in the class XI IPA1 as the control class. The results showed that the output rank for the mean value of the experimental class was bigger than the control class, 30.29> 14.09. The output statistic test showed sig. 2-tailed 0.00 < 0.05, and Zcount (-4.25) < Ztable (-1.64). These mean that H0 was rejected and Ha was received.

ABSTRACT [Relationship between Groundwater Surface Depth with Salinity at the Coast of New Kungkai Beach and its Implementation on Discovery Learning Model]. The aims of this study were 1) to describe the relationship between groundwater surface depth with salinity in the coastal areas of new kungkai beach of Seluma, and 2) to determine the improvement of learning outcomes (cognitive) of high ability students, moderate and low by using discovery learning model on the concept of static fluid in class X computer and network engineering at SMK Negeri 3 Seluma. This research was a quasi experimental research with one groups pretest-posttest design. The results showed: 1) The relationship between depth with salinity has a value of 0.6478 with a significance level of 0.001 (<0.05); 2) Learning with discovery learning model can improve student learning outcomes on cognitive aspects (knowledge). Increased cognitive results can be seen from the average value of the initial test, the final test and the average value of gain in the class x Tkj is high-ability groups are at high criteria with a value of 0.75 gain in the group is in the criteria medium with the value of gain 0,52 and in the low group were in moderate criteria with a gain value of 0.44. There is a difference in learning outcomes between the high, medium and low groups. The difference is shown by Fcount > Ftable (4.04 > 3.35) with a significance level of 5%. Keywords: Groundwater surface depth; salinity; discovery learning model; SMKN 3 Seluma.

This research aimed to analyze the difference of learning outcomes by using Student Facilitator and Explaining model and direct learning model on Digital Simulation subject at class X TKJ SMKN 1 Tilatang Kamang. The problem in this study was the student learning result which were still under KKM on Digital Simulation subjects at SMKN 1 Tilatang Kamang. Type of this research was Quasi Experiment. The sample was taken through Probability Sampling technique. The research samples were class X TKJ A  and class X TKJ B. Class X TKJ A as sample for experiment class using Student Facilitator and Explaining  model and class X TKJ B as sample for control class using direct learning model. Data analyzed based on post-test experiment class and control class, then analyzed for normality test, homogeneity test and hypothesis test. From the experimental class, the research results obtained an average of 82.47, while the control class was averaged of 76.94. Result of hypothesis calculation at significant level α = 0,05 found tcount> ttable that is 1,78> 1,699, because tcount was bigger than ttable, so null hypothesis (H0) was rejected and alternative hypothesis (Ha) was accepted.

Abstract This study aimed to reveal the difference of the basic ability of scientific work development between students who are teached using discovery learning and conventional learning. This study used quasy experiment with The Non Equivalent Pretest-Posttest Design. The subyek which are 58 VIII grade students in one of junior high school in Palu City are chosen with simple random sampling. Data were collected by observation sheets (check list) and were analyzed by normality, homogenity, and t-test using IBM SPSS Statistic 22 program. The result shows that the significance of Sig (2-tailed) is 0.00 < 0.005, which means that H0 is rejected and H1 was accepted. In addition, the data of the basic ability of scientific work development showed that the value for students teached by the discovery learning model is 58.28% and students teached by the conventional learning model is 47.13%, so it can be concluded that there is a significant difference on the basic ability of scientific work development between students who are teached using discovery learning and conventional learning in the material of sight and optical devices.
