ABSTRAKPenelitian ini bertujuan untuk menggambarkan kemampuan Pedagogical Content Knowledge (PCK) guru biologi senior (mengajar > 20 th) dan guru junior ( mengajar < 10 th). Penelitian ini merupakan penelitian studi kasus, partisipannya adalah dua orang guru biologi junior dan dua orang guru biologi senior. Kemampuan ini diukur dengan meminta guru membuat CoRes dan PaP-eRs pada materi transportasi zat yang dilanjutkan dengan teknik wawancara. Data dianalisis dengan teknik deskriptif kualitatif. Hasil analisis menunjukkan bahwa guru senior memunculkan tujuh konsep penting yang harus diajarkan sedangkan guru junior memunculkan antara delapan sampai 10 konsep. Guru senior lebih fokus pada konsep-konsep yang cenderung menimbulkan miskonsepsi dan pada bagian sulit dipahami oleh siswa seperti konsep difusi dan osmosis, serta pembelajaran lebih kepada penggunaan metode. Guru senior lebih fleksibel menggunakan strategi mengajar, disesuaikan dengan kondisi dilapangan dan keadaan siswa. Guru junior lebih fokus pada kedalaman materi dan model-model pembelajaran yang akan digunakan. Penggunaan strategi cenderung kurang fleksibel, lebih dikaitkan pada perencanaan yang sudah dibuat. Kata kunci : Pedagogical Content Knowledge (PCK), biologi, guru berpengalaman, guru belum berpengalaman ABSTRACTThis study aims to describe the ability of a senior biology teacher (teaching > 20 years) and junior teachers (teaching < 10 years) on Pedagogical Content Knowledge (PCK). This research was a case study, and the participants were two junior biology teachers and two senior biology teachers. This ability was measured by asking teachers to make CoRes and PaP-ers on the transport of material substance, followed by interview. Data were analyzed with descriptive qualitative techniques. The analysis showed that the senior teachers raises seven important concept that should be taught while the junior teacher raises between eight to 10 concepts. The senior teachers were more focus on the concepts that lead to misconception, such as the concepts about diffusion and osmosis, and more to learning methods. The senior teachers were more flexible in the use of teaching strategies according to students conditions and circumstances. The junior teachers were focus more on the depth of the material and learning models that will be used. The use of strategies tend to be less flexible, more linked to the planning that has been made.

The aim of this research was to analyse students’ creative thinking ability and the process involved in the development of students’ creative thinking, as well as to examine the differences between male and female students, in order to provide a better understanding of both gender in creative thinking ability. Creative thinking is represented by four indicators; fluency, flexibility, originality, and elaboration. In this research students’ creative thinking was measured by using a Test of Creative Thinking Ability, which consisted of five open-ended questions, while the process of creative thinking development was obeserved throughout the classroom teaching-learning activities, as well as the strategies and approaches implied by the teacher. The result showed student’s creative thinking ability was adequate (59%), in which the students scored the highest number in fluency (71,2%), followed by elaboration (59,5%), originality (58,5%), and flexibility (46,8%). Meanwhile, the process of creative thinking development was considered generally adequate in supporting students’ creative thinking ability, the score of the whole process in each indicators were: fluency (85,7%), flexibility (85,7%), originality (78,5%), elaboration (94,5%). Quantitative data analysis showed a statistically different results of fluency and elaboration between male and female students, while the result in flexibility and originality showed no-significant difference between both gender. Positive response related to students’ perception about their creative thinking ability were obtained using the students’ questionnaire as the instrument. Most of the students had a great perception of ther creative ability, where male students tend to have higher perspective about their creative ability than female students.

Laboratory activities and constructivism are two notions that have been playing significant roles in science education. Despite common beliefs about the importance of laboratory activities, reviews reported inconsistent results about the effectiveness of laboratory activities. Since laboratory activities can be expensive and take more time, there is an effort to introduce virtual laboratory activities. This study aims at exploring the learning environment created by a virtual laboratory and a real laboratory. A quasi experimental study was conducted at two grade ten classes at a state high school in Bandung, Indonesia. Data were collected using a questionnaire called Constructivist Learning Environment Survey (CLES) before and after the laboratory activities. The results show that both types of laboratories can create constructivist learning environments. Each type of laboratory activity, however, may be stronger in improving certain aspects compared to the other. While a virtual laboratory is stronger in improving critical voice and personal relevance, real laboratory activities promote aspects of personal relevance, uncertainty and student negotiation. This study suggests that instead of setting one type of laboratory against the other, lessons and follow up studies should focus on how to combine both types of laboratories to support better learning.

Both students and teachers have misconceptions about Force and Motion, often caused by teachers not being well-prepared to teach the accepted scientific theory. Besides, teachers rarely or never use a cognitive conflict strategy in their teaching. The present study is aimed at investigating the use of a discrepant event to facilitate preservice elementary teachers' conceptual change on Force and Motion concepts. The main objectives were to (1) investigate conceptual changes in Force and Motion concepts and (2) track students' conceptual change and their learning progression of these concepts. The research method used an intervention with a mixed method design. Second-semester students (N=120) participated in this study. The research instrument consisted of background information of respondents and their belief of conceptions about Force and Motion. The preliminary study using Direct Instruction and discussion methods. Once students' conceptual change profiles were known, remedial teaching was conducted through Reflective Conceptual Change Modelassisted Visual Multimedia. The research findings have shown that a discrepant event could help participants engage in conceptual change and have better explanations than before. The profile of their conceptual change and pattern of learning progression are discussed.

AbstrakTujuan dari penelitian ini adalah untuk mengidentifikasi tingkat pemahaman siswa dan guru SD tentang hakikat sains (NOS). Jenis penelitian ini adalah penelitian deskriptif dengan metode survei. Purposive sampling digunakan sebagai teknik pengambilan sampel. Sampel dalam penelitian ini adalah siswa dan guru SD dari Kabupaten Kuningan dan Kabupaten Purwakarta di Jawa Barat, serta dari Kabupaten Kendal dan Kota Surakarta di Jawa Tengah. Kuesioner yang berisi 30 item pernyataan yang dikembangkan oleh peneliti dalam konsultasi dengan dosen, guru, dan kepala sekolah yang didasarkan pada literatur yang relevan digunakan sebagai instrumen dalam penelitian ini. Hasil penelitian menunjukkan bahwa siswa memahami tingkat NOS pada kriteria Cukup dengan skor 65 sedangkan guru pada kriteria Baik dengan skor 72. Temuan dari penelitian ini menunjukkan bahwa rentang skor pemahaman NOS guru tidak selalu memiliki efek positif pada pemahaman NOS siswa. Akhirnya, penelitian ini merekomendasikan bahwa guru harus memahami NOS dan pembelajaran reflektif eksplisit, dan bagaimana mengajarkan NOS dengan pembelajaran reflektif eksplisit. Understanding of the nature of science (NOS) by elementary school students and teachers AbstractThe purpose of this study was to identify the understanding level of elementary students and teachers of the nature of science (NOS). This type of research was a descriptive study with a survey method. Purposive sampling was used as a sampling technique. Sample in this study were students and teachers from Kuningan Regency and Purwakarta Regency in West Java, and from Kendal Regency and Surakarta City in Central Java. A questionnaire containing 30 items of statements developed by researchers in consultation with lecturers, teachers, and principals which based on the relevant literature was used as an instrument in this research. The results showed that the students understanding levels of NOS at the Immediate criteria with a score of 65 while the teacher on the Good criteria with a score of 72. Findings from this study indicate that the range of teachers NOS understanding scores did not always have a positive effect on students NOS understanding. Finally, this study recommends that teachers have to understand with NOS and explicit-reflective learning, and how to teach NOS with explicit-reflective learning.

The nature of science has not been taught as a teaching material at school in Indonesia. This study aims to reveal the understanding of teachers and primary students about the nature of science. This study was a survey research with descriptive approach. Data were collected through closed questionnaires for teachers and students.
