The Ability of Generic Science at Observation and Inference Logic Prospective Chemistry Teacher in Organic Chemistry Experiment

The ability of generic science at observation and inference logic is very important in scientific work. This description of the research aims to describe the ability of generic science observation and inference logic chemistry education students in organic chemistry experiment activities. The subjects of study was conducted on 79 chemistry student teachers. Research activities include the analysis of the results of the pretest methodological and conceptual mastery of students expressed through Vee diagram, evaluation of students' ability, both individually and in groups for observation and inference logic every activity of organic chemistry experiment. Organic chemistry experiment as research objects include distillation experiment, solubility tests and recrystallization, the composition chain hydrocarbons, alcohol-phenols, aldehydes and ketones. At the end of each experiment done scoring results of scientific work for observation and inference logic, presentation of the results of the experiment, and report experimental posttest evaluation. All data pretest scores, postes, the report every trial of observation and inference logic is processed and interpreted. Research results found for the distillation experiment, solubility and recrystallization found chemistry student teachers have the ability generic science observations reach the N-gain average of 0, 462 or moderate level of achievement. Experiment arrangement chain hydrocarbons, alcohols phenols, ketones and aldehydes obtained value of N-gain average of 0.468 or moderate level of achievement. The results show the ability of logical inference in the category based on the value of N-gain. The ability of generic science, observation, inference logic, prospective chemistry teacher, organic chemistry experiment.
