<![CDATA[The aim of this research is to describe the effectiveness of problem solving learning in improving communication and inference skills in colloid system material. Subjects in this research were students of XIIPA1 and XI IPA2 classrooms in Persada Junior High School in Bandar Lampung in academic year 2011-2012 where students of both classrooms had the same characteristics. This research used quasi experiment method and pretest-posttest control group design. Effectiveness of problem solving learning method was measured based in n-gain value. The results showed that average n-gain values of communication and inference skills were 0.28 and 0.31 respectively. It could be concluded that the problem solvinglearning in colloid system material was effective in improving inferring skill with high category and communication skill with medium criterion.Keywords : problem solving learning, communication and inference skills]]>

<![CDATA[Abstract:The objective of this research is to describe effectiveness of Numbered Head Together (NHT) technique of cooperative learning model in improving electrolyte and non electrolyte solutions and redox reaction concept masteries. This research used quasi expewriment method with Non Equivalent Control Group Design. Population in this research was all Grade X students in YP UNILA senior High School in Bandar Lampung from classroom X1 to X11 in event semester of academic year 2011/2012. Samples were classroom X3 and X4 as experiment classrooms using NHT learning model. Samples were selected using purposive sampling. Clasroom X4was selected as control by using conventional learning.The results showed that N-gain average values of concept masteries in experiment and control classrooms were 0.599 and -0.477 respectively. The hypothesis test results showed that the classrooms with NHT technique of cooperative learning model had higher levels of activities and concept masteries compared to classroom with conventional learning. The conclusion of this research was that the NHT technique of cooperative learning model was effective in improving electrolyte and non electrolyte solutions and redox reaction concept masteries.

<![CDATA[The observation results showed that the average marks for colloid system material of students in classroom XI IPA 1 in State Senior High School 3 in Bandar Lampung in academic year 2009-20010 was 62.56. The determined minimum accomplishment criteria (or KKM) for chemistry subject in all classrooms XI IPA was 68. Students’ motivations in learning chemistry were low. This could be seen from irrelevant students’ activities to learning such as doing other tasks, sleeping and chatting. One of efforts to improve students’ learning motivations and concept masteries in colloid system material is by implementing guided discovery learning. The objective of this research is to improve percent of students’ learning motivation and concept mastery averages with guided discovery learning. This was a classroom action research and conducted in two cycles. Research data were data of students’ learning motivation obtained from observation sheets and data of concept mastery obtained from formative tests. The results showed that there were improvements of averages of students’ learning motivations (46.92%) and concept masteries (13.87%) from cycle I to cycle II. Keywords : guided discovery learning, students’ learning motivations, concept masteries ]]>
