Abstract

AbstractThis aims of this study were to determine whether there was a significant different of student achievement, determine how much influence of direct instruction models assisted by modelling the way strategy toward student achievement, determine the correlation between response and student achievement of experiment class and control class. This study used quasy experimental research with pretest-posttest non-equivalent control group design. The sample of this research were X B as experimental class which taught using direct instruction models through modelling the way strategy and X C as control class wich taught using conventional method. Achievement test, questionnaire response, observasion sheet and interview guidelines ware used as the research instrument. According to independent-t test toward student achievement data, there was no significant difference of student achievement between those clasess (Asym.sig.(2-tailed) of 0,342). Learning using direct instruction models through modelling the way strategy gave 14,80% effect on improving student achievemen influenced by teacher. According to Person Correlation, there was no correlation between response and student achievement of control class (Sig.(2-tailed) of 0,306). According to Kendall’s Correlation, there was no correlation between response and student achievement of experiment class (Sig.(2-tailed) of 0.398). Keyword: Direct Instruction, Modeling The Way, Hydrocarbon.

Abstract

Abstrak: Penelitian ini bertujuan untuk menentukan ada tidaknya perbedaan pemahaman konsep siswa pada materi koloid, antara siswa yang diajar menggunakan model guided discovery dengan model pembelajaran konvensional dan besarnya pengaruh model tersebut terhadap pemahaman konsep. Sampel dipilih berdasarkan teknik purposive sampling yaitu kelas XI IPA 1 sebagai kelas eksperimen dan kelas XI IPA 2 sebagai kelas kontrol. Bentuk penelitian yang digunakan adalah eksperimen semu dengan rancangan yang digunakan adalah nonequivalent control group design. Alat pengumpulan data yang digunakan yaitu tes kognitif dan lembar observasi. Berdasarkan hasil uji U-Mann Whitney diperoleh perbedaan pemahaman konsep antara siswa yang diajar menggunakan model guided discovery dengan menggunakan model konvensional dengan rata-rata hasil tes kognitif berturut-turut 77,07 dan 63,25. Model guided discovery juga memberikan pengaruh sebesar 43,45% terhadap pemahaman konsep siswa.   Kata Kunci : guided discovery, pemahaman konsep, koloid Abstract: This research aims to know differences in student’s understanding of concept on material coloid, between students who are taught by using guided discovery and conventional models and the influence of this model to understanding the concept. Sample was choosen by purposive sampling technique, XI IPA 1 as the experiment class and XI IPA 2 as control class. The research form used was quasi experimental and the research design that used is a non equivalent control group design. The tool for collecting data is cognitive test and observation paper. The result of the U-Mann Whitney we can show the differences understanding of concept between students who are taught by using guided discovery and conventional models with average value of cognitive test in 77,07 and 63,25. The guided discovery model is also an impact of 43,45% of the student's understanding of the concept.   Keywords: guided discovery, understanding of concept, coloid.
