Abstract

This study aims to determine the effectiveness of POE learning model on non-electrolyte and electrolyte material in improving comunicating skills and  conclude skills. Subjects in this study was of class X1 SMA Budaya Bandar Lampung totaling 32 people. This research uses a pre-experimental method with One Group Pretest Posstest Design. This research data was data of comunicating skills and the skills of data conclude, data analysis using the percentage of mastery learning (KKM ) which has been set and n-Gain. The results showed that persentage of mastery learning and n-Gain who achieved by 75% and n-Gain comunicate skills 0.68 (medium category). And than who achieved  KKM 81.25% and n-Gain conclude skills  0.69 (medium category).  Conclution this research showed that the POE learning model of non-electrolyte and electrolyte solution material is effective in improving the comunicate skills and conclude skills student for class X1SMA Budaya Bandar Lampung.Tujuan pada penelitian ini adalah mendeskripsikan efektivitas model pembelajar-an POE pada materi larutan non-elektrolit dan elektrolit dalam meningkatkan ke-terampilan mengkomunikasikan dan menyimpulkan.  Subjek penelitian ini yaitu siswa kelas X1 SMA Budaya Bandar Lampung yang berjumlah 32 siswa.  Peneli-tian ini menggunakan metode Pre-eksperimental dengan One-group pretest-poss-test Design.  Data pe­neliti­an ini adalah data keterampilan mengkomunikasikan dan keterampilan menyimpulkan.  Analisis data menggunakan persentase ketun-tasan belajar (KKM) yang telah ditetapkan dan n-Gain.  Hasil penelitian menunjukkan bahwa persentase ketuntasan belajar dan n-Gain keterampilan mengkomunikasikan mencapai KKM yaitu 75% dan n-Gain sebesar 0,68 (kategori sedang).  Sedangkan ke­terampilan menyimpulkan yang men­capai KKM yaitu 81,25% dan n-Gain sebesar  0,69 (katagori sedang).  Kesimpulan penelitian ini menunjuk­kan bahwa pembelajaran dengan model POE pada materi larutan non-lektrolit dan elektrolit efektif dalam me­ningkat­kan keterampilan mengkomunikasikan dan menyimpulkan siswa kelas X1 SMA Budaya Bandar Lampung. Kata kunci:  keterampilan mengkomunikasikan, keterampilan menyimpulkan, larutan non-elektrolit dan elektrolit, model POE.

Abstract

This research was aimed to develop and describe validity and practicality of an interactive e-book based on chemical representation on buffer materials. Research was conducted using the method of Research and Development (RD). This research was conducted in 4 state high schools and 2 public high schools in Shouthern Lampung district. The teachers response data on the content suitability and attractiveness aspects were obtained by using a questionnaires and response data on the readability aspect were obtained by using questionnaire. In this research the validator gave an assessment to the aspects of construction, readabitily, suitability of content interactive e-book in a high category and is declared valid. The theacher responses and student responses are also categorized high and the result of this study indicate that in interactive e-book based on chemical representation on buffered solvent material developed is valid and practical.Penelitian ini bertujuan untuk mendeskripsikan validitas dan kepraktisan e-book interaktif berbasis representasi kimia pada materi larutan penyangga. Metode penelitian yang digunakan adalah metode Research and Development (RD). Penelitian ini dilakukan di 4 SMA Negeri dan 2 SMA Swasta di Kabupaten Lampung Selatan dengan sumber data satu guru Kimia dan 20 siswa/siswi.

Abstract

This study aims to describe the effectiveness of discovery learning model on buffer solution materials to improve students’ science process skills. This research is a quasi-experimental study with the matching-only pretest and posttest control group design.Population on this study is all students of class XI IPA of SMAN 1 Sukadana EastLampung in even semester of the 2021/2022 academic year. The sampling techniqueused purposive sampling and obtain class XI IPA 3 and class XI IPA 2 as experimental class and control class, respectively. Hypothesis testing used the analysis of the average post-test value calculation using the difference test of two average by t-test. The results showed that: (1) the average post-test scores of students’ science process skills in the experimental class were significantly different from post-test scores in the control class which is high-categorized of 0,71. Thus, it can be concluded that blended learning with discovery learning model is effective to improve students’ science process skills. Keywords: discovery learning, blended learning, buffer solution, science process skills.
