Abstract

This study aims to determine the effect of learning strategy the power of two on the activity of students in Biology learning. This research design uses posttest-only control design with quasi experimental method. The population in this study is the entire class in X class in one high school at Palembang consisting of 5 classes, with 141 students. Sampling is using purposive technique. The sample of this study is X IPA 3 class with 36 students as experimental class and X IPA 2 class with 36 students as control class. In the learning process, the experimental class is taught by using the power of two learning strategy and control class using conventional method (lecture). Data collection is from observation sheet and questionnaire of student learning activity which have been tested its validity by using Aiken's V formula. The result of this study shows that the average of student learning activity in the experimental class in 2 meetings is 83,05% of the students who have been active in very active category. In control class, the percentage of active students 55,46% is active category. Result of data analysis that is using t-test with significant level 0,05 obtained tarithmetic = 9,693 while ttable = 1,994 seen that tarithmetic > ttable. Therefore, Ha is accepted and H0 is rejected thus it can be concluded that the power of two's learning strategy can have an effect on student's learning activeness. Increasing the liveliness of learners can optimize the motivation, cooperation, responsibility, reading interest, and learner activity in the learning process. Keywords: learning strategy, learning, the power of two, student activity

Abstract

This study aims to determine the benefits of school environment as a source of learning on the Plantae material (Spermatophyta) by using contextual learning on the activities of high school students of high school. This research used descriptive research type. Sampling in this research is done by purposive sampling technique (purposive sampling) considering student ability and activity in various class samples. Research sample in this research is class X MIPA. This research was conducted for three meetings with assessment instrument in the form of observation sheet which will be assessed by 5 (five) observers. The observation sheets are activity observation sheets, student attitudes and skills as well as individual student final reports. The results of this study indicate that the activities of students including active category (B) with 82% percentage of assessment. Likewise the attitude of students who belong to either category (B) with the same percentage of assessment. Another case with the skills of students who are classified as excellent (A) with a higher percentage of assessment that is 89%. Meanwhile, in the final report students individually more than 50% of students category is very good (A) with the percentage of students overall 83.8% which indicates the final report of students done with good category (B). If accumulated as a whole the percentage of assessment of each instrument is 84.42% with good category with the predicate B. Therefore, the school environment can be utilized as a source of biology learning especially Spermatophyta material by using contextual learning model.
