One effort to improve the ability of learner to pronounce alphabet is through talking stick model. It was a classroom action research based on preparation of learning which reflected the steps that must be done by the teacher. The procedure consisted of two cycles and each cycle consisted of two meetings. Based on the data obtained from the implementation of action cycle II showed that the number of package C learner that can afford is 18 or 86% learners, while the number of learner who could not afford about 3 people or 14 %. Thus the learning of the 100% talking stick model has been successful in accordance with the predefined performance indicators by the researcher. The results caused by the maximization and effectiveness of the application of the talking stick model on learning English, especially English alphabet pronunciation.

This study aims to improve the learning outcomes of acid and alkaline material chemistry by using Inquiry Based Learning (IBL) of students of Class XI IPA 2 SMA Negeri 5 Makassar. This study is a classroom action research conducted in three cycles. Each cycle consists of planning, execution, observation and reflection. The population of this study amounted to 36 students. The focus of this research is student learning outcomes. The learning result data is obtained from the results evaluation test which is carried out at the end of the cycle. About the evaluation test each learning outcomes are equipped with five alternative answers. The result of data analysis showed that the average of student learning outcomes after the application of IBL in cycle I was 71.53 with 72.22% classical completeness, then rose to 78.79 with 83.33% classical completeness in cycle II, and increased to 83.97 with classical completeness 91.67% in cycle III. Based on the results of this study can be concluded that the application of IBL learning model can improve student learning outcomes of acidic and alkaline materials.
