TL;DR: In this paper, the authors test the effectiveness of guided PjBL model to improve students' cognitive learning result and students' science process skills by using a purposive sampling technique.
Abstract: Latar belakang yang mendorong penelitian ini adalah hasil belajar kognitif siswa yang belum memenuhi kriteria ketuntasan minimal serta pembelajaran belum mengoptimalkan keterampilan proses sains. Tujuan penelitian ini adalah untuk menguji keefektifan model PjBL terbimbing untuk meningkatkan hasil belajar kognitif siswa dan keterampilan proses sains siswa. Penelitian kuantitatif ini dalam bentuk quasy experimental design dengan jenis non equivalent control group design. Kelas eksperimen dikenai pembelajaran menggunakan model PjBL terbimbing, kelas kontrol dikenai pembelajaran menggunakan model PjBL. Subjek penelitian 55 siswa kelas V SD N Kleteran I dan SDN Banaran. Data berupa hasil belajar kognitif dan psikomotor keterampilan proses sains siswa dikumpulkan melalui observasi, tes dan dokumentasi. Penelitian menunjukkan hasil sebagai berikut: (1) terdapat perbedaan hasil belajar kognitif antara kelompok siswa yang mengikuti model PJBL terbimbing dengan kelompok siswa yang mengikuti model pembelajaran PJBL, diperoleh nilai thitung = 2.32. Nilai ini lebih besar dari ttabel yang sebesar 1.67. (2) Terdapat perbedaan keterampilan proses sains antara kelompok siswa yang mengikuti model pembelajaran PjBL terbimbing dengan yang mengikuti model pembelajaran PjBL (thitung = 3.18 > t tabel = 1.67). Peningkatan hasil belajar dan keterampilan proses yang menggunakan model PjBL terbimbing lebih baik dari pada PjBL. Jadi model PjBL efektif untuk meningkatkan hasil belajar dan keterampilan proses siswa.Background to conduct this study is the students’ cognitive learning result which has not fulfilled minimum mastery criteria and the learning process which has not optimized science process skills. The research problems of this study are does guided PjBL model effective for improving students’ cognitive learning result? does guided PjBL model effective to optimize students' science process skills? The purpose of this study is to test the effectiveness of guided PjBL model to improve students’ cognitive learning result and students' science process skills. This quantitative research was in the form of quasy experimental design (quasi-experiment) with nonequivalent control group design types (classes are experimental and control). Experimental class, in the learning process was using guided PjBL model subjected learning, while, the learning process in control class was using PjBL model. The research subject were 55 students of V graders in SD N Kleteran I and SDN Banaran, it was determined by using purposive sampling technique. Data was in the form of cognitive and psychomotoric students' learning result of science process skills, it was collected through observation, test, and documentation. The result of this study are as follows: (1) there are differences in cognitive learning result between groups of students who follow guided PjBL model and group of students who follow PjBL model, the value (tcalculate = 2:32> ttable = 1.67), (2) there are differences in learning result between the science process skills of students who take guided PjBL model and group of students who take PjBL model (tcalculate = 3:18> ttable = 1.67). The conclusions of the study are guided PjBL model is effective to improve and science process skills and students’ learning result.

TL;DR: In this paper, a qualitative research was conducted in SMAN 4 Magelang in academic year 2013/2014 to know the students' conception and also their conceptual changes in learning materials of temperature and heat.
Abstract: Untuk mengetahui konsepsi dan perubahan konseptual siswa pada materi suhu dan kalor, dilakukan penelitian kualitatif pada siswa SMA N 4 Magelang tahun pelajaran 2013/2014. Penelitian dimulai dengan pengumpulan data dan observasi terhadap siswa. Tahap selanjutnya yaitu melakukan uji coba soal tes tulis pada kelas regular. Hasil dari uji coba soal kemudian dijadikan bahan untuk melakukan tes tulis pada kelas X dan XII IPA unggulan. Soal tes tulis merupakan soal essay berupa soal konseptual. Setelah itu, dilaksanakan tes wawancara dengan sampel siswa yang jawabannya memiliki banyak peluang/kemungkinan. Konsepsi siswa berbentuk konsepsi ilmiah, alternatif, dan paralel. Konsepsi paralel siswa merupakan perpaduan antara konsepsi ilmiah dan alternatif serta perpaduan dua konsepsi alternatif. Faktor yang melatarbelakangi munculnya konsepsi pada siswa meliputi pemahaman kurang mendalam, apresiasi konseptual, intuisi kehidupan sehari-hari, dan pengetahuan sebagai struktur teoritis. Bentuk perubahan konseptual siswa signifikan pada perubahan menuju konsepsi ilmiah sedangkan perubahan konsepsi alternatif dan paralel terjadi meski dengan jumlah yang sedikit. In purpose to know the students’ conception and also their conceptual changes in learning materials of temperature and heat, a qualitative research was conducted in SMAN 4 Magelang in academic year 2013/2014. The reseach was started by collecting data dealing with the research and observing the students. The next step was the trial of written test to regular class. The result of the trial was used as the test given to the superior class of ten and twelfth graders. The given written test is conceptual in the form of essay. After conducting the written test, interview test was conducted. The samples are the students who had many possibilities in answering the written test. Based on the research result, the students’ concepts are scientific concept, alternative concept, and parallel concept. The parallel concept is the combination between scientific concept and alternative concept and also the combination between two alternative concepts. Factors influencing and triggering the students’ conception are shallow understanding, conceptual appreciation, daily intuition, and knowledge as the theoretical structures. The conceptual changes significantly approach the scientific conception while the changes of alternative conception and parallel took place although in small precentage.

Abstract: Tujuan penelitian ini untuk menguji efektivitas konseling kelompok teknik cognitive restructuring untuk mereduksi prokrastinasi akademik ditinjau dari jenis kelamin pada siswa SMK PGRI 2 Ponorogo. Jenis penelitian randomized pretest–postest control group design diaplikasikan dalam penelitian ini dengan melibatkan sejumlah 16 siswa yang memiliki skor prokrastinasi akademik tinggi. Teknik analisis data yang digunakan adalah statistik non parametrik dengan menggunakan uji u mann whitney untuk menguji efek cognitive restructuring terhadap prokrastinasi dan menggunakan uji wilcoxon signed rank test untuk mengetahui efektivitas intervensi antara jenis kelamin laki – laki dan perempuan. Hasil penelitian ini menunjukkan bahwa konseling kelompok CBT teknik cognitive restructuring efektif untuk mereduksi prokrastinasi akademik. Teknik cognitive restructuring cocok untuk siswa laki–laki maupun perempuan. Hal ini terbukti dengan tak ada perbedaan skor postes secara signifikan diantara keduanya. The aim of this study was to examine the effect of group counseling of Cognitive-Behavior Therapy with cognitive restructuring techniques to reduce academic procrastination between male and female students of SMK PGRI 2 Ponorogo. The randomized pretest-posttest control group design was applied, and 16 students were involved in present study. Data were analyzed using non parametric statistics of Mann Whitney U test for examining the impact of cognitive restructuring on academic procrastination and Wilcoxon signed rank test for determining the effect of cognitive restructung between male and female students. The results showed that CBT group counseling with cognitive restructuring techniques was effective for reducing academic procrastination. The cognitive restructuring techniques were suitable for both male and female students. It was reflected from the absence of significant differences effect of cognitive restructuring between them.
