Abstract

This research aims to improve students scientific process and aspects of knowledge, as well as to know activity and the response of the students through the application of science learning assisted PhET Simulation Program to 30 students of eight grades in junior high school. This research was experimental research with one group pretest-posttest design. Data were analyzed by descriptive quantitative results: (a) Students science process skills are increase with an average value post test results of 80 (N-gain; 0.71 with high criteria); (b) Students aspects of knowledge are increase with an average value post test results of 80 (N-gain; 0.74 with high criteria); (c) Frequency of activities that do experiment/ observation that by 18.3 percent while activities that students do at least is behavior that is not relevant to KBM by 3%; (d) The students positive response to learning process (83% with very strong criteria). Conclusion of this research that application of science learning assisted PhET simulation program can improve students process skills and aspects of knowledge.

Abstract

The topic Nutrition and Energy Transformation concepts are abstract and difficult to comprehend. To overcome such a difficulty, it is necessary to develop a set of instructional package incorporating Macromedia flash. The Dick and Carey instructional development model was used for that purpose. Before the implementation of the instructional programs, all of the components of the instructional package consisted of lesson implementation plan, media, student worksheet Guided discovery type, student workbook, and assesment intrument, were validated and met the prescribed criteria. Implementation in the school only observe one class without replication. Thirty Junior High School Students involvedin this investigation using One Group Pretest-Postest Design. Result of this research shows the lesson plan is good (3,5), learning modul is good (3,0), student worksheet type Guided discovery is good (3,5), media is good (3,5), and student achievement mastery also good (3,0). Implementation lesson plan in class using direct instruction is good (3,67), with reliability around 82% (good/reliable). Student activity commonly is good (13,25) with reliable average 92%. Student respon is good, above 83%. Student achievement increase with Gain score above 0.7. The result of observation of the teaching and learning process, conducted during its implementation, showed that there was a consistency betweenthe prescribed teaching and learning experienced with its implementation. Students had met the 80% minimum mastery criteria. So it can be concluded that the development instructional package is effective to increase the junior High School student achievement. Materi proses perolehan nutrisi dan transformasi energi pada tumbuhan hijau sulit dipahami oleh siswa karena bersifat abstrak, sehingga tidak dapat dilihat secara nyata. Atas dasar itu, perlu kiranya mengembangkan perangkat pembelajaran dengan bantuan tampilan media Macro flash. Untuk itu, telah dilakukan suatu penelitian pengembangan perangkat pembelajaran, yang berorientasi Dick and Carey dan bertujuan meningkatkan hasil belajar siswa. Penelitian ini hanya dilakukan pada satu kelas saja, tanpa melakukan ulangan. Subyek penelitian 30 orang siswa kelas VIII SMP Negeri 22 Surabaya, dengan rancangan Short Case Pretest-Postest, sedangkan analisis data dilakukan secara deskriptif kualitatif. Hasil penilaian RPP baik (3,5), BAS baik (3,0), LKS bercirikan Guided discovery baik (3,5), media baik (3,5) dan tes hasil belajar baik (3,0). Pengelolaan pelaksanaan di kelas dengan pembelajaran langsung termasuk baik (3,67) dengan reliabilitas 82% (baik/reliabel). Aktivitas siswa secara umum baik (13,25)dengan reliabilitas rata-rata 92%. Respon siswa secara umum tertarik sebesar 83% lebih. Tes hasil belajar menunjukan peningkatan tinggi dengan Gain score diatas 0,7. Simpulan penelitian menunjukkan bahwa pengembangan perangkat pembelajaran biologi berbasis Macromedia flash di SMP, layak digunakan, keterlaksanaan pembelajaran, aktivitas dan respon siswa baik, serta dapat meningkatkan hasil belajar siswa.

Abstract

This study aims to produce LKPD based on communication and collaboration with CORE learning model a decent to improve learning outcomes and Train Communication Skills on students in the subject matter of the Nervous System in Humans. This research have used 4D development model that has been tested on students in class XI IPA 4, XI IPA 5, and XI IPA 6 in SMAN 18 Surabaya with research design one group pretest and posttest design. Research data has been obtained through the method of validation, observation, test, and questionnaire. The results are analyzed descriptively quantitative and qualitative. The results showed that: (a) LKPD with CORE learning model and learning tools developed categorized as valid; (b) the implementation of learning activities is very good; (c) student learning outcomes on the knowledge aspect increases with high criteria; (d) the students provide very positive response to the learning that has been implemented. Based on the analysis and discussion, it is concluded that LKPD with CORE learning model is suitable to be used to improve student learning outcomes on high school students.

Abstract

This research was done by developing science learning materials (lesson plans, student’s worksheets, student’s book, and learning achivement test) based on guided inquiry learning model using 4D development model to facilitate student’s science process skills and improving student’s learning achivement on environmental pollutions matter. The objective of this research was to trial learning materials in 35 of junior high school’s students with one group pretest-postest design. Results were analyzed by descriptive quantitative-qualitative are: (1) Validity of learning material valid category (3.00); (2) Practicalitybased on: a) Feasibility of instruction good category (3,8); b) Readability of worksheets and student’s book students stating that the content and appearance of worksheets and student’s book is interesting; c) The response of students very positively (85.6%); (3) Effectiveness based on: a) Student’s activities who stand out were practice science process skills is high category (38,5%); b) Student’s science process skill in very high category as shown by student’s worksheet achivement (3,46); c) student learning achivement increased (N-Gain: 0.2-1.0).
