Effect of Collaborative Murder Learning Model on Cognitive Ability and Learning Motivation

Research with this quasi-experimental method aims to determine the influence of collaborative learning models of Mood, Understand, Recall, Detect, Elaborate, and Review (MURDER) on the cognitive abilities and motivational learning of learners. The instrument used to measure the cognitive abilities in the form of written tests refers to the Bloom's taxonomy, while the instrument for measuring learning motivation are motivation questionnaires. Learning cognitive ability data in the form of increase in Pretest and Posttest i.e. the normalization Gain (N-Gain) tested statistically using Wilcoxon test. Wilcoxon test results at a significance level α = 0.05 with 95% confidence level indicates calculated W of 0, while the table W (0.05) (30) amounted to 137. It can be concluded that Ho is rejected meaning that the cognitive abilities in the experiment class and the control class differ significantly. Analysis of learning motivation data was taken from a questionnaire with a Likert scale 1-4. The results of the t test calculation at the significance level α = 0.05 95% confidence level showed calculated t of 0.75, and table t (0.975) (59) of 2,001. Because the t 0.975 (59) < t < t 0.975 (59), it can be concluded that Ho is accepted meaning there is no significant difference in students' learning motivation in the experimental class and the control class. In this study the MURDER collaborative learning model has an effect on cognitive ability, but does not affect learning motivation of students.

Everyone is a Teacher Here Method towards Student Learning Outcomes on Kingdom Animalia Topic

This study aims to improve learning outcomes of students' cognitive abilities in the kingdom animalia concept. The subjects of this study were students of SMAN 1 Surade in class X-5 and X-3 with a total of 41 and 36 people. The research method used in this study is Quasi Experimental Design with Pretest-Posttest control group design research design. The instrument used was question of cognitive ability in the form of multiple choice as the main data source and a questionnaire as supporting data. The cognitive abilities netted from the instruments are C1 (knowing), C2 (interpreting), C3 (sorting) and C4 (interpreting). The results of the study show that the cognitive abilities of students after following Learning Everyone is a Teacher Here has increased from the average value of grades the initial test 62.19 increased to 78.79. Based on testing the hypothesis at the final test, the calculated t value of 262.9 is greater than the t table value of 244. This shows that the learning outcomes achieved there were no significant differences. Students respond towards Learning Everyone is a teacher here on each statement interpreted pretty well on average.

Hands-On Contextual Learning Experimentation on Psychomotor Abilities

The purpose of this study was to determine the effect of contextual learning models based on hands-on activities on students' psychomotor abilities. This type of research is a quasi-experimental using pretest posttest control group design. The results showed the psychomotor ability of students in the experimental class averaged 79.63 which was categorized as "good" while the control class obtained an average of 68.93 which was also categorized as "good". Hypothesis testing using t test shows the results of tcount = 4.73 while the t table = 2.002 so that H0 is rejected and Ha is accepted. This means that there is a significant difference between learning using hands-on contextual learning models compared to contextual learning models based on conventional practicum student psychomotor abilities. The results of the correlation coefficient test, the experimental class got the value of rxy = 0.9965 and the contribution was 99.30% while the control class was rxy = 0.987 and the contribution was 97.42% with the value of r (0.05) (30) = 0.361. Thus rcount> rtable which means that there is a very strong relationship between psychomotor abilities and cognitive knowledge on water pollution material based on the interpretation coefficient interpretation table in the two classes.
