Abstract

ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran perubahan konseptual terhadap hasil belajar siswa pada pokok bahasan Tekanan di SMP Negeri 1 Merapi Barat. Jenis penelitian ini merupakan penelitian quasi eksperimen, dengan desain penelitian adalah nonequivalent control group design. Sampel dalam penelitian ini sebanyak 72 siswa yang diambil secara acak dalam 2 kelas yaitu 36 siswa kelas VIII-A sebagai kelas eksperimen dan 36 siswa kelas VIII-B sebagai kelas kontrol. Kelas eksperimen diberi perlakuan dengan menggunakan model pembelajaran perubahan konseptual, sedangkan kelas kontrol hanya diajarkan dengan pembelajaran konvensional metode ceramah. Baik kelas kontrol maupun kelas eksperimen sama-sama diberi tes awal (pre-test) dan tes akhir (post-test). Berdasarkan analisa data nilai rata-rata pre-test untuk kelas eksperimen adalah 41, dan nilai rata-rata pre-test kelas kontrol adalah 34. Selain itu, nilai rata-rata post-test untuk kelas eksperimen yaitu 83 dan nilai rata-rata post-test untuk kelas kontrol yaitu 62. Dari analisa data gain termormalisasi diperoleh = 3,89 dan = 1,996. Ini berarti sehingga hipotesis nol (H0) yang menyatakan tidak ada pengaruh model pembelajaran perubahan konseptual terhadap hasil belajar siswa Pokok Bahasan Tekanan di SMP Negeri 1 Merapi Barat, ditolak, dan hipotesis alternatif (Ha) yang menyatakan ada pengaruh model pembelajaran perubahan konseptual terhadap hasil belajar siswa Pokok Bahasan Tekanan di SMP Negeri 1 Merapi, diterima.ABSTRACTThis research aimed to determine the effect of conceptual change learning model for result of student learning on the subject of pressure in State Junior High School Number 1 in West Merapi. This type of research is a quasi experimental study, the study design was nonequivalent control group design. The sample in this study, 72 students were chosen randomly in the two class, which is 36 students of class VIII-A as the experimental class and 36 students of class VIII-B as the control class. Experimental class were treated by using a conceptual changes learning model, while the control class is only taught by conventional teaching model. Both the control and experimental classes were given an initial test (pre-test) and final test (post-test). Based on the data analysis of the average pre-test for the experimental class is 41, and the average pre-test control class is 34. In addition, the average post-test for the experimental class is 83 and the average post-test for the control class is 62. From the analysis of the data obtained normalized gain = 3,89 and = 1,996.

Abstract

Telah dilakukan penelitian tentang “Peranan software ELGAS dalam meningkatkan pemahaman konsep kimia fisik dan keterampilan berpikir kritis mahasiswa pendidikan kimia”. Software ELGAS merupakan model pembelajaran KFI berbasis TIK. Implementasi sofware ELGAS dalam pembelajaran KFI berbasis TIK telah dilakukan terhadap 26 mahasiswa yang dijadikan sebagai kelas eksperimen. Sedangkan kelas kontrol melakukan pembelajaran secara konvensional. Berdasarkan analisis data ternyata tidak terdapat perbedaan nilai rerata yang signifikan antara penguasaan konsep kelompok rendah dengan kelompok tinggi. Namun demikian dilihat dari koefisien variansi (KV) skor post-test, ternyata kesenjangan skor yang didapat oleh mahasiswa kelompok rendah lebih baik dibandingkan dengan mahasiswa kelompok tinggi. Keterampilan berpikir kritis yang dapat dikembangkan dengan baik melalui pembelajaran KFI berbasis TIK terjadi pada topik perubahan perubahan keadaan gas. KBK tersebut adalah kemampuan dalam mengatur strategi.

Abstract

Penelitian deskriptif ini difokuskan pada tiga permasalahan hal yaitu pertama penelitian flora yang terdapat di kampus Universitas La Trobe dan di lingkungan SMU wilayah Bendigo, Melbourne Utara. Kedua jenis-jenis tumbuhan apa saja yang sudah dikembangkan/diteliti universitas tersebut untuk kepentingan industri dan bisnis. Ketiga mengobservasi upaya-upaya mereka dalam melestarikan flora asli Australia melalui pendidikan. Landasan teoritik yang berkaitan dengan masalah ini adalah hubungan antara klimatologi dengan flora yang terdapat di daerah sub tropis. Faktor-faktor klimatologi ini adalah: Suhu, kelembaban, cahaya dsb., yang berbeda dengan daerah tropis, demikian halnya dengan floranya. Hasil pengamatan (observasi) di universitas ini menunjukkan bahwa implementasi oendidikan untuk memanfaatkan flora untuk industri dan oengelolaan lingkungan: oelestarian flora, fauna, konservasi air dan tanah sudah diwujudkan baik dalam teori maupun praktek. Metode penelitian dilakukan dengan metode dan pendekatan: tanya jawab, diskusi dan mengamati langsung flora yang terdapat di lingkungan universitas dan sekolah, serta pemanfaatannya. Kesimpulan: pertama, flora di daerah ini menunjukkan variasinya sedikit, namun jumlahnya besar (a.l. Eycalyptus sp.). Pemanfaatan flora yang terdapat di lingkungan kampus untuk keperluan industri dan farmasi, dilakukan melalui Riset dan Pengembangan (Research and Development) secara teratur dan terus menerus. Hal yang sama pada pelestarian flora dengan malalui implementasi pendidikan. Rekomendasi: Variasi flora di suatu wilayah local, regional, nasional dan internasional seyogyanya dipelajari dengan baik dan dicari guna manfaatnya dalam meningkatkan kesejahteraan penduduk serta berupaya melestarikannya untuk generasi yang akan dating, yang dilakukan melalui pendidikan di sekolah dan universitas.

Abstract

ABSTRAKKesamaan istilah dalam tahap-tahap Penelitian Tindakan Kelas (PTK) yaitu Perencanaan, Pelaksanaan tindakan, Pengamatan dan Refleksi dengan tahap-tahap kegiatan dalam lesson study yaitu : Plan, Do dan See membuat orang yang belum begitu mengenal lesson study secara mendalam akan mempertanyakan hal ini. Samakan PTK yang lebih dikenal dengan Classroom Action Research (CAR) dengan Lesson Study? Apakah tujuan dari kedua kegiatan ini sama? Memang tujuan utama dari kedua kegiatan ini adalah sama yaitu meningkatkan mutu pembelajaran. Akan tetapi ada aspek lain yang membedakan PTK dan Lesson study yaitu Lesson study merupakan suatu strategi untuk meningkatkan profesionalisme guru melalui kegiatan belajar dari pembelajaran orang lain. Sebenarnya perbedaan prinsip antara PTK dan Lesson study adalah : PTK berbasis penelitian, sedangkan lesson study tidak selalu berbasis penelitian dan lesson study mempunyai cakupan yang lebih luas dari pada PTK, bahkan tidak hanya PTK yang dapat dilaksanakan dalam kegiatan lesson study, akan tetapi jenis penelitian lain juga bisa dilaksanakan dengan persiapan instrumen yang lebih terencana, agar mendapatkan data yang diharapkan. ABSTRACTSimilar term in CAR (Classroom Action Research) steps are planning, acting, observing and reflecting with an activity steps in lesson study are plan, do and see make people that don’t know much about lesson study will keep asking. Are the CAR and lesson study the same? Is the purpose of this two are the same? Although the main purpose of this two activities are the same that is to improve the quality of the teaching, but there’s another aspect that differentiate the CAR and lesson study. The lesson study is a strategy to improve professionalism of the teachers, through teaching activity from other people’s teaching. Actually the main difference between the CAR and lesson study is that CAR is research basis while the lesson study is not always research basis. The lesson study has more coverage than CAR. Even more is not only the CAR that can be done in lesson study but also other researchs are can be done with good planned instrument preparation to get the expected data.

Abstract

Chemistry learning based on the intertextuality of chemistry demands relationship among chemistry representsation on three levels, which are macrocospic, microscopic, and symbol level with the daily experience of students and the social interaction developed by teachers. Through the research entitled “Pengembangan CD Pembelajaran Interaktif Kimia SMA Berbasis Intertekstualitas sebagai Alternatif Model Pembelajaran”, we will have a learning CD for teachers using competency standard and basic competency; concepts and indicators; the representation of chemistry materials on three levels macroscopic, microscopic, and symbol; learning description; and student work sheet. Before making the learning model, we will execute a standard analysis on the content of KTSP 2006, so we will get the concepts and indicators; potray the learning process of teachers in class and analyse the reference books both text books and hig school books. The data source for this research is the table of according to concept and indicators with competency standard and basic competency; the observation of learning process in class; the analysis table of three levels; hydrolysis materials from text books in high school and university; and the descriptive table of hydrolysis concept learning. The supporting instruments used are quistionaires to know the students expereince and essay texts to know the concept understanding the students have after the learning process. From the standard analysis of the content of KTSP 2006, we have three concepts and eight indicators. The first concept is classifying salt according to the forming compounds with the indicators (1) explain salt coming from strong acid and strong base; (2) explain salt coming from strong acid and weak base; (3) explain salt coming from weak acid and strong base; (4) explaining salt coming from weak acid and weak base. The second concept: hydrolysis is the ions reaction with water molecul producing ion H+ and or OHwith indicators (1) describe salt hydrolysis and (2) explain various kinds of salt hydrolysis. The third concept is salt undergoing hydrolysis can be acid base, or neutral with indicators (1) measure qualitatively the characteristic of acid, base, and neutral of salt by using some indicators and (2) count the ph of hydrolysied salt condensation. The observation result will be recorded on video then transcribed into text and smoothed to be a basic text. After that, we will do propotition degradation to gain global structure. Then, this data will be classified based on the intertextuality of chemistry. From the result of the data analysis we can conclude that the model teacher has not used the learning based on the intertextuality chemistry yet. The learning process of the model teacher is dominated by the symbol level and the social interaction developed by the teacher is not optimal; besides, there is no aspect of daily experience discussed in the learning process. The development of learning model based on intertextuality begins by making hydrolysis material representation in three levels. The compilation of hydrolysis material representation is executed in three steps: analysing high school books and university; making representation device; conducting validation to experts and practitioners; and final revision. In macroscopic level we do demonstration of the condensation and litmus test on soaps, alum, and salt and also the determination pH of the salt by using pH meter. In microscopic level we demonstrate pictures of species salt solution before and after hydrolysis process. Then in symbolic level we demonstrate the formula of salt molecul, ionisation reaction equation and hydrolysis on salt, and mathematic formula in determining the concentration H+ and OHto count pH and pOH. Later on, we make a description of the learning process equiped with learning media; clarify the demonstrations; present the model in front of experts and practitioners; record it in a learning CD. Meanwhile, the application of the learning CD in class will be conducted in the next research in the second year.
