Abstract: The characteristic of the material of environmental pollution requires the real object from surrounding as learning resources. Hence, it demands the students move in or out of the classroom activity. Therefore, it is required to develop a student’s worksheet based on experiments that are expected to explain the theory about nature that can be revealed by experimental activities, especially on the material of environmental pollution. This study was Research and Development from the thiagarajan model of 4 D (Define, Design, Development and Disseminate). However, this study was conducted until the development stage only without the disseminate stage, because this study did not use it for a large scale. The instruments used in this study were validation sheets and respondent questionnaires for student’s worksheets based on experiments. The result of this study showed that the validity percentage based on the value of three expert validators with an average of 93,52 % included the very valid category. Meanwhile, the average percentage results of the respondent questionnaire included very applicable category from the first and the second tryouts were 90,98 % and 89,16 %, respectively. In conclusion, student’s worksheet based on experiments can be stated as the teaching materials which has been validated and very applicable to be used in the learning process. Keywords: Student’s worksheet based on experiments; Environmental pollution; Development

Abstract

Student learning outcomes were influenced by learning model which applied by teacher. One of the learning model required active student involvement in the learning process was the guided inquiry approach. The guided inquiry learning model emphasized on the discovery and mastery of the concept through the experimental process. This research aimed to identify between the differences of student’s learning outcomes by using guided inquiry learning model and using direct learning model on the sub-material of deposition reaction and the influence of guided inquiry learning model on students’ learning outcomes. This research used quasi experimental design and this purposive sampling technique to determine the sample. The sample of research was the students of grade XI IPA SMA Muhammadiyah 1 Pontianak. Data collection used a test and observation method. Data analysis used SPSS 17.0 for Windows. Based on the result, there were differences between learning outcomes using guided inquiry learning model and direct learning model. This research used Effect Size (ES) with ES = 2,44 as high category with 49,27%, mean guided inquiry learning model gave high effectiveness to students’ learning outcomes. Based on the research results, the guided inquiry learning model was effectively applied in SMA Muhammadiyah 1 Pontianak.Keywords: Learning outcomes, Guided inquiry, Deposition reaction

Abstract

ABSTRACTThe low level of students’ learning outcomes at MAN 1 Pontianak on solubility and the result of solubility multiply was caused by lack of students’ understanding on basic concept. This research had the purpose to find out the difference between the students’ learning outcomes which were taught by using Teams Games Tournament (TGT) type of Cooperative Learning Method Assisted Question Box and the lectures teaching method assisted Question Box as well as to know the effect of TGT type of Cooperative Learning Method Assisted Question Box. This research was Quasi Experimental Control Pretest Posttest Group Design. The sampling system was simple random sampling technique. The techniques of data collection used measurement technique, observation and direct communication (interview). The result of data analysis showed that the mean score of experimental class was 73.8 which was higher compared to the mean score of control class which was 62.97. The result of statistical analysis using U-Mann whitney test with α 5% obtained 0.00 value which was smaller than α value (0.00 <0.05). It meant that there was difference between the learning outcomes in experimental and control class. The calculation result using effect size showed the value of ES 0.91 which was included in high category. It could be concluded that TGT type of Cooperative Learning Method assisted Quesion Box gave high effect on the improvement ofstudents’ learning outcomes which was 31.86 %.
