Abstract: This research has the purpose to know the students’ achievement in teaching buffer solution by implementing the inquiry strategy based on collaborative. The population of this research are all high school students year XI in SMA Negeri 16 Medan, which is the population in that school has 4 classes of XI grade year at academic year 2013/2014. The test is standardized with the reliability is 0.836. The research result showed that the data are normal distribution and the samples are homogeneous. Experimental class which is taught by inquiry strategy based on collaborative can increased the students achievement in the average of the gain is 0.6856 and in control class which is taught by direct instructional is 0.465. The statistic data shown the significance different with the tcount (10.74) > ttable (1.688). The hypothesis conclude that students’ achievement which is implemented the inquiry strategy based on collaborative is higher significantly than direct instructional. In addition the cognitive aspect which is improved by implementing the inquiry strategy based on collaborative is C2 (Comprehension) is 0.76 included as high category. The implementation of collaborative learning in preservice teacher have improve student in create learning media. Collaborative learning can be applied in preservice teacher lecturing

Key words: inquiry, collaborative learning, students’ achievement, chemistry
