Reconstruction Model Education of Laboratory Research Course Context Chemical Clay, Decision Making Problem Solving (PSDM) Based, to Improve Research Thinking Skills From ChemistryTeacherCandidates

This research purpose to reconstruct the lectures of laboratory research clay context-based problem solving decision making (LRPSDM) in one LPTK of Jayapura Papua. The research method was mixed methods research-embedded. At this stage of the reconstruction of the intervention used didactic models (MER-LRPSDM) lay context. Reconstrution model based of problems finding unscientific research laboratory. MER stages starting from the analysis of the literature, discourse analysis to produce teaching materials classes used as infrastructure implementation MER-LR PSDM. Students participants (30 people) were divided into 2 groups (control and experimental). The control group using conventional methods, and the experimental group using the lecture method LRPSDM. The results showed N-average gain posttest understanding the clay concept of control group was 0.73 (high category), the ability to laboratory research design the control group was 0.43 (medium category), understanding the clay concept of experimental class was 0.77 (high category), ability to laboratory research design experimental class was 0.71 (high category), ability PSDM thinking based the classroom experiments, 0.71 (high category). There is a growing understanding of the concept, research skills, and thinking research on experimental class students. Based on the data normality test, there is data that is not normal so that the statistics used were statistically non-parametric indevendent 2 samples, Mann Whitney test, and using SPSS version 22. (Mann Whitney test, sig. less than), Ho there was no difference in average significantly. In understanding the concept is sig. (0.354) greater than (0.05), meaning that there is no significant difference between the understanding of clay concepts between the control and experimental classes, the ability to design laboratory research is sig. (0.001) less than (0.05) means that there are differences in average very significant between the control and experimental class. Obtaining the average value of understanding the clay concept of the control class is 80.7, and 84.1 being the experimental class. The average value of the control class research capacity (58.8), and the experimental class (80.7). So that the reconstrution model of laboratory research studies clay context PSDM based, very excellent to used improve student research thinking, so students can to carry out scientific research, independent, and free from plagiarism.
