Abstract

Biology learning in the 21st century requires students to understand complex genetics concepts, particularly the inheritance of traits in living organisms based on Mendel's laws. Computational thinking skills are essential for helping students systematically analyze and solve these intricate genetic patterns. This study aims to analyze the relationship between computational thinking skills and cognitive learning outcomes on the material of the inheritance of living creatures’ traits based on Mendel’s law. The research method used is descriptive with a correlational study. This study employed a descriptive correlational research method, conducted at SMAI PB Soedirman with a sample of 87 twelfth-grade science students from 203 students with an average age of 17-18 years and a balanced proportion of male and female selected through simple random sampling. The instruments used included questionnaires to measure computational thinking skills and tests to assess cognitive learning outcomes in genetics. Data analysis involved descriptive statistics to summarize the data and correlational analysis using Pearson’s Product-Moment to explore the relationship between variables. The tests that have been carried out show that there is a significant positive and linear relationship between computational thinking skills and cognitive learning outcomes of genetic trait inheritance based on Mendel’s law. The strength level of the relationship between the two variables is moderate.

Abstract

Bilingual student worksheet in Biology Lessons was currently not available in SMAN 68. Such worksheet is useful for increasing student engagement during learning process, encouraging students to apply the knowledge into daily living activities, and also helping student to understand English in Biology. Therefore, this research was aimed to develop bilingual student worksheet with contextual approach on human reproductive system topic. It is held at SMAN 68 Jakarta on February to May 2012. This research and development consisted of three stages: need assessment, development, and feasibility test. The result of feasibility tests showed that 88.4% obtained from material expert, 80% from media expert, 95.5% from linguist expert, 85.14% from Biology teacher, 71.96% from the smaller group student, and 77.6% from the larger group student. Based on the results, it was concluded that the worksheet can be used as teaching material for senior high school student in Biology lesson on human reproductive system topic.

Abstract

The aim of this research was to know the effect of the use of bilingual student worksheet toward students learning outcomes on the human reproductive system topic. This research was conducted at SMAN 68 Jakarta on April-May 2012. The method was quasi-experimental with posttest-only design. The Simple random sampling technique selected 30 students grade 11 of IPA 4 included in experimental group and another 30 students grade 11 of IPA 3 as control group. This research used instrument of multiple choice test with five alternative answers. Prerequisite Testing for normality of Kolmogorov Smirnov and homogeneity testing of F-test showed a normal distribution and homogenous data. The hypothesis testing on cognitive learning result using t-test at α = 0.05 indicated that tcount (2.35) > ttable (2.00) which rejected the H0, whether the hypothesis testing on affective learning result using t-test at α = 0.05 showed that t count (3.84) > t table (2.00) which rejected the H0. Based on the results, it can be concluded that there was an effect of using the bilingual student worksheet toward students learning outcomes on the human reproductive system topic.
