<![CDATA[The learning process is strongly influenced by the ability and accuracy of teachers in selecting and applying the learning model. The model can be applied to improve of simple explanation and inferencetion skill is a model of problem solving. The purpose of this study was to describe the model of problem solving that are effective in improving simple explanation and inferencetion skills on the material electrolyte and non-electrolyte solution. This research use a quasi-experimental methods with Non Equivalent (Pretest and Posttest) Control Group Design. The sampling technique used purposive sampling technique. The samples in this study were high school students Bandar Lampung Fransiskus X4 and X5 class even semester 2012-2013 School Year. Effectiveness of the learning model of problem solving is measured based on a significant increase in gain and t-test. The results showed the average value of n-Gain a simple explanation skills for the control and experimental classes 0.47 and 0.75, while the average n-Gain inferencetion skills to control and experimental classes 0.54 and 0.66. This suggests that learning is effective in improving of simple explanation and inferencetion skills with problem solving.Keywords: Problem Solving, a simple explanation skills, inference skills]]>

<![CDATA[The objective of this research is to describe effectiveness of the learning model of problem solving in improving communication and inference skills in buffer and hydrolysis lesson. Samples in this research were students of State Senior High School 1 Tumijajar of classes XI Sciences 2 and XI Sciences 3 even semester School Year 2011-2012 that have equal academic abilities. This research used a quasi experiment method with Nonequivalent Control Group Design. Effectiveness of the learning model of problem solving was measured by significant differences in control class and experiment class, shown by significant gain. Based on the results of this research, average value of N-gain for communication skills in control and experiment class were 0,53 and 0,65; and average value of N-gain for inference skills in control and experiment class were 58 and 0,66. Hypothesis testing in this research used test two average different with t-test. Hypothesis result test show that class that used learning model of problem solving had higher communication and inference skills than class with conventional learning model. This indicated that learning model of problem solving was effective to improving communication and inference skills in buffer and hydrolysis lesson.

<![CDATA[The objective of this research is to describe effectiveness of effectiveness predict-observe-explain(POE) learning model in oxidation-reduction reaction material in improving skill in predict and classifying. The effectiveness of the POE learning model in this research is indicated by the significant difference between experiment classroom and control classroom.Population in this research was all 105 grade X students in Paramarta 1 Seputih Senior High School in academic year 2011-2012 which were distributed in classroom X1, X2, and X3. Samples in this research were classroom X1 as the experiment classroom using POE learning model and classroom X2 as control using conventional learning. Samples were taken using purposive sampling. The research results showed that the n-gain average value of skill in predict in control and experiment classrooms were 0.30 and 0.46 respectively, and the n-gain average value for skill in classifying for control and experiment classrooms were 0.37 and 0.64 respectively.Results of hypothesis test showed that classroom with POE learning model had higher skills in predict and classifying compared with control classroom. This indicated that POE learning model was more effective to improve skills in predict and classifying. Keywords: predict-observe-explain (POE), skills in predict and classifying]]>
