Abstract

The aim of this research is to determine the effect of Cooperative Integrated Reading and Composition based Contextual Teaching and Learning. This research population is XI Sciences of senior high school 1 brebes 2011/2012. First data analysis showed that the population data are normally distributed and homogeneous, so the sampling technique which used is cluster random sampling. From the result of the draws, XI Science-1 as an experiment class (Cooperative Integrated Reading and Composition Based contextual Teaching and Learning) and XI Science-5 as a control class (conventional learning). Final data analysis showed that learning product both classes are normally distributed and have equal variances. In the test of correlation, obtained 0,732 of rb value, which showed a height correlation, so Cooperative Integrated Reading and Composition Based Contextual Teaching and Learning has height effect on student learning product in colloids. This learning contributes to student learning product=54%. The learning product of experiment and control class had reached completeness. classical learning completeness which achieved by experiment and control class are respectively 95% and 87,5%. The average value of affective and psychomotor in experimental class is better than the control class. Based on this research, we can conclude that Cooperative Integrated Reading and Composition based Contextual Teaching and Learning assisted has a positive effect on learning product in senior high school 1 brebes.

Abstract

The observations in SMA N 1 Demak show the results of student achievement still has not met with the thoroughness studied classical. This research is done to determine the effectiveness of virtual laboratory towards students' achivement about buffer solution and hydrolysis of SMA N 1 Demak. The population is the eleventh grade student of science. Sample was conducted by random sampling technique, obtained a XI IPA 1 as the experimental class get the learning used virtual laboratory and the XI IPA 2 as the control class get the learning used lecture method. To collect the data the writer used documentation, test, observation and questionnaires. The results of the research show that the average students' achivement in experiments class is 80.55 while the control class is 76.82. The percentage thoroughness studied classical of experiment class is 94.74% while the control class is 73.68%. On average students gave positive responses (happy) to each of the indicators contained in the questionnaires. From the analysis can be concluded that virtual laboratory is effective towards the students’ achievement about buffer solution and hydrolysis of SMA N 1 Demak.
