Analysis of Genetic Misconceptions Student Biology Education at STKIP Persada Khatulistiwa Sintang

During the learning process of genetic course, students were difficult to assess the material because of its abstraction. Genetics materials contained technical terms that cannot be memorized and pronounced easily by the students. Its concepts were hard to be understood because it does not provide a conceptual framework. Students were not deconstructed and construct the genetic knowledge by using their critical thinking and logical reasoning; it was make the concept of genetic were not understood correctly. Some of the wrong exist concepts about genetic are the students tried to keep concepts confidently that they have gotten when study in the previous level of education by reading and materials has taught in the school, it was said as misconceptions. The student’s misconceptions could be transferred to their students when they teach their students in the future. This is a qualitative research; it aimed to reveal the students genetic misconceptions. The samples of the research are 25 students in the 6th semester of biology education study program at STKIP Persada Khatulistiwa Sintang. The result of the research found that students misconceptions include the scope of genetic, genetic material, genetics of mendel, chromosome mutation, DN

PKM PELATIHAN PENGEMBANGAN ASESMEN AUTENTIK UNTUK PEMBELAJARAN BERBASIS PRAKTIKUM BAGI KELOMPOK GURU IPA

Based on observations at partner schools i.e SMP Nusantara Indah Sintang and SMP Panca Setya 2 Sintang, it is seen that the assessment used is traditional assessment in the form of written test, where the assessment is less able to express students’s skill and attitude. Therefore, the servant team and partner schools collaborate with to solving the problem through the PKM program. The PKM program aims to improve teachers skills in designing and developing performance assessments, in order to empower and reveal student’s skills and attitudes. This PKM Program conducted by in service method in the form of training and mentoring. The training is the techniques of designing an authentic assessment in the form of performance assessment, which is used in practice-based learning. The results of the training and mentoring program was developed group performance assessments and personal performance assessments, both of which include the lattice and test or performance sheet. Key Wods: Training, Skills, Performance Assessments

PKM Pelatihan Pemanfaatan Bahan Bekas Sebagai Media Pembelajaran IPA bagi Kelompok Guru IPA

Based on observations at SMP Nusantara Indah Sintang and SMP Panca Setya 2 Sintang as a schoolspartner, it is seen that the condition of the laboratory is inadequate wherethe available of the tools and materials are less. Science Teachers did not innovate and create creations to overcome the problem. In addition, practicum activities are rarely done, including in utilizing the surrounding environment. Science Teachers tend to do learning process with theory. Therefore, the joint proponent cooperates to overcome the problem through the program of Pengabdian Kepada Masyarakat (PKM). This PKM program is aims to improve teachers' skills in designing and developing learning media with unused materials. The method used in the achievement of the goal is the implementation of inservice in the form of training and mentoring. The training was carried out is the training of techniques to design learning media with used materials. The results of the training is there are six media developed i.e linear motion, simple machine, digestive system, additive substances, structure and function of plant tissue, and circulatory system

PEMBELAJARAN BERBASIS PRAKTIKUM DAN ASESMENNYA PADA KONSEP SISTEM PEREDARAN DARAH UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS DAN SIKAP ILMIAH SISWA SMA

PEMBELAJARAN BERBASIS PRAKTIKUM DAN ASESMENNYA PADA KONSEP SISTEM PEREDARAN DARAH UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS DAN SIKAP ILMIAH SISWA SMA (Hilarius Jago Duda, 0808825) Abstrak Penelitian ini bertujuan untuk mengetahui peningkatan dan menganalisis kemampuan berpikir kritis serta mengetahui dan mengidentifikasi sikap ilmiah siswa pada materi sistem peredaran darah sebelum dan sesudah belajar dengan pembelajaran berbasis praktikum. Metode penelitian yang digunakan quasi experiment dengan “static group pretes-postes design”dilaksanakan di SMA Santa Maria 1 Bandung kelas X1 semester II pada tahun ajaran 2009/2010. Sampel penelitian diambil secara langsung dari semua sampel yang ada, karena di sekolah tersebut hanya terdiri atas dua kelas IPA. Pengumpulan data dilakukan melalui tes awal dan tes akhir pada kemampuan berpikir kritis dan sikap ilmiah siswa serta data lainnya yaitu asesmen kinerja siswa (personal dan kelompok), angket siswa dan angket guru. Data dianalisis dengan uji beda rerata (uji t) dengan menggunakan data tes akhir. Hasilnya berbeda signifikan baik pada kemampuan berpikir kritis maupun sikap ilmiah siswa. Rerata N-Gain pada kelas eksperimen dan kontrol untuk kemampuan berpikir kritis berturut-turut adalah 0,64 (sedang) dan 0,57 (sedang), sikap ilmiah siswa 0,16 (rendah) dan 0,14 (rendah). Asesmen kinerja menunjukan untuk kelas eksperimen yaitu 97,50 lebih baik daripada kelas kontrol yaitu 90,72. Secara umum asesmen kinerja untuk kedua kelas baik asesmen kinerja personal maupun asesmen kinerja kelompok cukup baik dan hampir semua siswa aktif dalam pembelajaran biologi. Guru maupun siswa memberikan tanggapan positif terhadap pembelajaran biologi. Disimpulkan bahwa pembelajaran berbasis praktikum lebih baik dari pada pembelajaran konvensional

PRAKTIKUM BIOLOGI BERBASIS MASALAH DAN KEMAMPUAN BERPIKIR KRITIS SISWA

  Abstract: The learning of science in Indonesia is always involving the verbal learning of concepts and principles of science. Such learning leads the students to only acknowledge science terms based on memorizing, but without recognizing the significance. A better learning must be a learning which sharpens and develops the higher level of thinking ability, one such ability is critical thinking ability. Learning by conventional methods such as speech, discussion and inquiry does not sharpen critical thinking ability. Taking the problem into account, the solution is using learning models to sharpen the critical thinking ability of students. One such model is problem-based practicum model. This model involves students who will actively, use all their senses, optimize their ability of thinking and explore the fact in the actual reality by lifting the authentic problem

Enhancing different ethnicity science process skills: problem-based learning through practicum and authentic assessment

Problem-Based Learning (PBL) is a constructivist learning with the potential to enhance students' science process skill. The implementation of PBL has revealed many advantages; however, a free exploration from a highly complex environment may result in a heavier workload of memory. Accordingly, practicum method can be used to overcome the shortcomings of PBL with the support of authentic assessment. This research aimsed to investigate the effect of PBL through practicum supported by authentic assessment, PBL, and conventional learning on science process skills of Dayak and Malay students in Animal Physiology lectures. The research used a quasi-experimental research design with a pretest-posttest non-equivalent control group design with 3 x 2 factorial design. Data collection involved a science process skill test. The data were analyzed descriptively and inferentially with ANCOVA. Significant differences between groups were assessed with LSD test. The result showed that the learning model influenced students' science process skill. The PBL model implemented through a practicum and supported with authentic assessment was the most influential being significantly different to both PBM model and conventional learning. Ethnicity did not significantly affect the students' science process skill. There was no interaction between learning model and ethnicity toward students' science process skill
