Abstract

Module based on guided discovery learning can be used as an alternative to improve student’s activeness and understanding the concept. This research aims to develop redox reaction and electrochemical cell module based on guided discovery learning and reveals its validity and practicability. The type of this research is a development research using 4-D development model. The research instrument used was a questionnaire in the form of validity and practicality sheet. This module was validated by 3 UNP chemistry lecturers and 2 chemistry teachers of SMAN 10 Padang. Practicality test were conducted on 2 chemistry teachers and 32 twelfth grade students of SMAN 10 Padang. Data were analyzed by Cohen’s Kappa formula. The results of the validity test showed that the module has a very high validity category (k=0.83). Practicality test results by teachers and students showed that the module has high practicality category (k=0.79 and 0.80). Based on the results of this research, it can be concluded that the module developed was valid, practical.

Abstract

This study aims to produce teaching materials based material reaction rate guided inquiry (learning cycle: the phase of exploration, discovery / establishment of the concept and application) in the form of a valid experiment worksheets and practical use in learning chemistry in SMA / MA. This type of research included in Research and Development (R & D). The development model used in this study is the four-D (4-D). The research instrument is the validation sheet and questionnaire. Data from the study consists of three aspects, namely, the validity, the practicalities and effectiveness of teaching materials. Data validity and practicalities processed using Cohens Kappa formula, and the effectiveness of data using a percentage In this study is limited to the validity and practicalities. Validation of teaching materials from the aspect of content, language and graffiti and feasibility of construction. Data from the validator obtained an average score moment kappa was 0.87, and the results of practical analysis conducted with a limited test in MAN 3 Padang obtained an average score of 0.84 practicality value of 0.78 of teachers and students. From the analysis worksheets that showed 86 % of students working on critical questions and exercises contained in LKS experiments that have been made can be answered students. These results indicate that LKS guided inquiry-based experiments developed extremely valid and practical use in learning chemistry

Abstract

Quasi experiment research with randomized control posttest group only design was carried out to determine the effectiveness of using a discovery learning based module on students learning outcome. Grade XI MIA-1 to MIA-4 students academic year 2015/2016 in SMAN 7 Padang became population of this study. Through cluster sampling technique, grade XI MIA-1 and grade XI MIA-4 were chosen as experiment and control classes respectively. The experiment class was taught using discovery learning based module in buffer solution topic while the control class was taught the same topic conventionally without the module. Research instrument used was cognitive learning outcome test with multiple choice form. Data showed that the mean test score of experiement class (78.84) was higher than that of control class (71.09). Normality and homogenity test proved that both classes were homogeneous and normally distributed. T-test, as data analysis taken, showed that t-count (3,51) is bigger than t-table (1.67). Thus, it could be concluded that students’ cognitive learning outcome in experiment class is significantly higher than that in control class. The use of discovery learning-based module in buffer solution topic was effective in increasing learning outcome of grade XI MIA students in SMAN 7 Padang.
