Abstract

Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran resiprocal teaching dengan teknik mind mapping terhadap kemampuan metakognisi dan afektif pada konsep sistem sirkulasi kelas XI IPA SMA Negeri 15 Bandar Lampung. Metode penelitian yang digunakan pada penelitian ini adalah quasi experimental design.  Desain penelitian yang digunakan pada quasi experimental ini adalah Pretest-Posttest Control Group Design. Penelitian dilaksanakan pada tanggal 3 September s/d 14 September 2016 di kelas XI IPA SMA N 15 Bandar Lampung dengan teknik pengambilan sampel adalah probability sampling type simple random sampling. Sampel ini terdiri 2 kelas yaitu kelas eksperimen (XI IPA 2) dan kelas kontrol (XI IPA 1).  Berdasarkan hasil analisis data yang diperoleh uji hipotesis hasil belajar kemampuan metakognisi menggunakan uji Independent t-test Microsoft Exel 2007 dengan hasil thitung (1,713) > ttabel (1.67155) dan uji hipotesis hasil belajar afektif menggunakan uji Independent t-test Microsoft Exel 2007 dengan hasil thitung (2,30905)> ttabel (1.67155). Berdasarkan hasil uji  t, maka dinyatakan  Hi diterima artinya, ada pengaruh model pembelajaran Reciprocal Teaching dengan teknik mindmapping terhadap kemampuan metakognisi dan afektif pada konsep sistem sirkulasi kelas XI IPA SMA Negeri 15 Bandar Lampung.

Abstract

Science learning in elementary schools is often still dominated by conventional teacher-centered methods, which result in students being less active and their learning outcomes not being optimal. One alternative learning strategy that can increase student engagement is Think-Talk-Write (TTW), which encourages students to think, discuss, and express ideas in writing. This study aims to determine the effectiveness of the TTW strategy on students’ learning outcomes in science subjects. This research employed a quantitative approach using a quasi-experimental method. The research design used was a Nonequivalent Control Group Design. The sample consisted of two classes: an experimental class applying the TTW strategy and a control class using conventional learning methods. The instrument used was a 25-item multiple-choice test that had been validated and tested for reliability. Data analysis included normality test, homogeneity test, and t-test using SPSS software. The results showed that the data were normally distributed and homogeneous, meeting the requirements for conducting a t-test. The t-test results showed a significance value of < 0.05, indicating a significant difference in learning outcomes between students using the TTW strategy and those using conventional methods. Therefore, it can be concluded that the Think-Talk-Write strategy is effective in improving science learning outcomes among elementary school students.

Abstract

The character of caring for the environment must be grown from an early age. Environmental damage which was previously considered a local problem within a country, has now penetrated and spilled over into a global issue. The emergence of environmental problems is mostly caused by human activities. This indicates that human concern for the environment in which they live is starting to fade. Therefore concern for the environment needs to be instilled from an early age. The character of caring for the environment must be taught in junior high schools, one of which is through science learning. The purpose of this study was to form the character of caring for the environment in junior high school students through the science material learning model. The method used in this research is qualitative. Data was collected through documentation and literature studies. Data were analyzed through data reduction, data display, and conclusion drawing/verification which were restated through discussion in descriptive form. The results of the literature study show that the formation of a caring character for the environment through science learning can be done by designing student-focused learning. Science learning provides opportunities for students to interact with the environment directly. Several learning models that can be used by teachers to shape the character of caring for the environment in students, such as Problem Based Learning (PBL), Project Based Learning (PjBL), Contextual Teaching and Learning (CTL), and Outdoor Learning methods. Teaching materials and learning media also play an important role in shaping the character of caring for the environment in students.
