Abstract

 Chemistry’s phenomena can explained by multiple representation, they are macroscopis, symbolis, and submicroscopis dimention. Based on the fact, submicroscopis dimention is often diserted, especially when teach acid-base material because it is difficult to learn.  According to this case, teachers need the media for delivering material of chemistry. The research aim is resulting animation media of Arrhenius acid-base material based on multiple representation.This research used research and development (R & D) method by Gall, Gall and Borg in Putra (2012). But on this research, step only arrive to step of main product revision. Research and development on this research have three steps. They are needs analysis step, consist of literature study and field study, planning and developing product step, consist of planning product, developing product,validation, and revision product, and the last is field test step, whose test of the product then revision the product based on result of test.Result of this research was animation media of Arrhenius acid-base material based on multiple representation which have characteristics: 1) displaying science material of Arrhenius acid-base which be explained by multiple representation, 2) it has parts consist of opening, instructional, competence standard, basic competence, indicators of product cognitive, subject of acid-base solution, subject of indicators acid-base, subject of Arrhenius acid-base, subject of pH, and profile button, 3) the contents suitability aspect has high score that is 80% according to validator judgement and 80% according to teacher judgement, and also have the highest level in isteresting aspect that is 83.45% according students judgement.Key words :  animation media, multiple representation, Arrhenius acid-base

Abstract

The objectives of this research are to describe effectiveness of Numbered Head Together (NHT) learning model in redox reaction in improving symbolic language skill and to describe effectiveness of NHT learning model in redox reaction material in improving concept mastery.  Population in this research was all Grade X students in State Senior High School 1 Buay Bahuga in academic year 2011/2012. Samples were classroom X2 as experiment classroom and classroom X1 as control classroom. Samples were selected using purposive sampling. This reserach used quasi experiment menthod with Non Equivalent (Prestest and Posttest) Control Group Design). The effectiveness of NHT learning model was measured based on significant n-gain differences of symbolic language skill and concept mastery between NHT learning classroom and conventional learning classroom. The results showed that the average of n-gain of symbolic language skill for experiment and control clasrooms were 0.26 and 0.18 respectively, and the average n-gain of concept mastery for experiment and control classrooms were 0.29 and 0.23 respectively.  Based on hypothesis test, classroom with NHT learning model had higher symbolic language skill and concept mastery than classroom with conventional learning. This indicated that NHT learning was effective in improving symbolic language skill and concept mastery of redox reaction.Keywords: Numbered Head Together (NHT) Learning Model, symbolic language skill and concept mastery

Abstract

The aim of this research was to describe effectiveness of empirical inductive learning cycle model in improving of critical thinking skills of students in sub skills of analyzing arguments.  Indicators of critical thinking skills studied were identifying conclusions and seeing similarities and differences. Population was all 170 students of Grade XI State Senior High School 3 in Kotabumi. Samples were 34 students in XI Sains 2 class and 34 students in XI Sains 3 class that have equal academic abilities. This was a quasi experiment research using non equivalent control group design. Effectiveness of learning with empirical inductive learning cycle model was measured based on significant gain improvements of skill in analyzing arguments. The results showed that average value of n-Gain of skill in analyzing arguments in experiment and control classes were 0.62 and 0.42 respectively. The hypothesis result test showed that class which used empirical inductive learning cycle model had higher skill in analyzing arguments than class with conventional learning model. This indicated empirical inductive learning cycle model was effective to improve critical thinking of students in the acid base matery in state senior high school 3 in Kotabumi.Keywords: empirical inductive learning cycle, critical thinking skills of students
