Abstract

This research was aimed to describe the effectiveness of Pre-Lecture Quiz to improve student’s communication skill on Arrhenius acid-base topic. The research method used was quasi experimental with non-equivalen pretest-postest control group design. The sample selection was done by cluster random sampling, obtained XI IPA 1 as experimental class and XI IPA 2 as control class.  The effectiveness of Pre-Lecture Quiz was showed by the significant difference for average n-Gain of flexible thinking skill between the experiment and control class, for experiment class was 0.71 with high categorize and for control class was 0.55 with middle cateogorize. The conclusion of this research is effective Pre-Lecture Quiz and has a high effect size to improve the ability of communication on Arrhenius acid-base topic.Keywords: communication, Pre-Lecture Quiz, Arrhenius acid-basePenelitian ini bertujuan untuk mendeskripsikan efektivitas pre-lecture quiz untuk meningkatkan keterampilan komunikasi siswa pada materi asam basa Arrhenius.

Abstract

The objective of this research is to know effectiveness of problem solving learning in improving skill induct and considerate induction result . Population was 360 students of Grade X State Senior High School 12 in Bandar Lampung. Samples were X1 and X3 classroom. Every class has 38 students that have equal academic abilities. This was a quasi experiment research using non equivalent control group design. Effectiveness of problem solving learning was measured based on significant n-Gain improvements of showing the general thing and making conclution and hypotesis skill. The both are subindicator of  induction and considerate induction result. The results showed that average value of n-Gain of showing the general thing skill in experiment and control classrooms were 0.4 and 0.28 respectively; and average value of n-Gain for making conclution and hypotesis in experiment and control classrooms were 0.36 and 0.20 respectively. The result showed that classroom that used problem solving had higher induct and considerate result induction skill than classroom with conventional learning. This indicated that problem solving learning was effective to improve student’s induction and considerate induction result skill mastery of the concept at basic laws of chemistry.Keywords: Problem Solving, induction and considerate induction result skill

Abstract

The aim of this research is to describe the effectiveness of  learning cycle 3E  learning model in improving the skills of inference and mastery of concepts in chemical equilibrium material. Learning cycle 3E model is learning through a series of stages (phases of learning) learning phases include: (1) the exploration phase, (2) explanation of the concept phase, and (3) the application of the concept phase. This study used a quasi-experimental method with Non Equivalent (Pretest and Posttest) Control Group Design. Effectiveness of the learning cycle 3E model  is measured by an increase in n-Gain significant. The results showed the average value of n-Gain inference skills for grade control and experimental respectively 0.40 and 0.53, and an average of n-Gain the possession concept for the control and experimental classes respectively 0.44 and 0 , 48. Thus, it can be concluded that the learning cycle 3E learning model in chemical equilibrium material effective to enhance inferensi skill and mastery of concepts in medium categoryKeywords: Learning Cycle 3E, inference skills and mastery of concepts
