Abstract

This study aimed to determine theeffectiveness of seating formation towards student learning outcomes on interactions between organisms and their environmentsubject. The research design was pretest-posttest non-equivalent groups. The population was all students of VII grade of Junior High School 1 Gadingrejo. The samples were VII8, VII9, and VII10grades student which were selected by purposive sampling technique. This research data were the result of students pretest-posttest, students self-assessment sheets affective aspects, and students observation sheets psychomotor aspects. Cognitive aspects of learning outcome data were analyzed by One-Way Anova test and by Independent Sample t-test, affective and psychomotor aspects learning outcomes were analyzed by Qualitative Achievement Index and calculated the score improvement. The results showed that the I experiment class had the highest cognitives N-gain and score improvement (affective and psychomotor). So, there were differences of effectiveness of the three seating formations that applied towards student learning outcomes on interactions between organisms and their environment subject.Penelitian ini bertujuan untuk mengetahui efektivitas formasi tempat duduk terhadap hasil belajar siswa pada materi pokok interaksi antar makhluk hidup dan lingkungannya.

Abstract

This research aims was to determine the effect of PBL on metacognition skills and learning outcomes. The design was a nonequivalent pretest-posttest control group design. The research sample were the students of VIIA and VIIC amounted of 60 students that were selected through cluster random sampling technique. Data on metacognition skills wereobtained from questionnaires and data on learning outcomes obtained from pretest and posttest. Data on metacognition skills were analyzed descriptively while learning outcomes were analyzed by Independent Sample t-Test at 5% confidence level. The results showed that the experimental class metacognition skills were higher with the criteria of "developing very well" compared to the control class which had the criteria "already developed". The cognitive learning outcomes of the experimental class were also higher than the control class with the average N-gain in the experimental class of (0.39 ± 0.124) while in the control class (0.29 ± 0.157).Penelitian ini bertujuan menentukan pengaruh PBL terhadap keterampilan metakognisi dan hasil belajar peserta didik.

Abstract

This study aims was to measure science teachers in Labuhan Maringgai sub-district in planning and implementing the assesement. The samples of this research were 30 science teachers of SMP in Labuhan Maringgai sub-district. Qualitative data was analyzed by descriptive statistic technique. The results showed that the average of science teachers difficulties in planning and implementing assesement was sufficient. The highest percentage that caused teachers difficulties in planning assesement was pinning the learning objectives. While the problems that caused difficulties in conducting assesement were implementing affective domain assesement, especially in observing aspects and conditioning the assesement implementation. It can be concluded that the difficulties of science teachers in Junior High School in Labuhan Maringgai District in planning assesement had difficulty in determining assesement techniques and determining the form of assesement. The difficulty of assesement implementation was implementing the affective domain assesement, that domain can not be measured because the attitude and character of learners at any time may change.Penelitian ini bertujuan mengidentifikasi kesulitan guru IPA se-Kecamatan Labuhan Maringgai dalam merencanakan dan melaksanakan asesmen. Sampel penelitian adalah 30 guru IPA SMP se-Kecamatan Labuhan Maringgai. Data kualitatif dianalisis dengan menggunakan teknik statistik deskriptif. Hasil penelitian menunjukkan bahwa rata-rata kesulitan yang dialami guru IPA dalam merencanakan dan melaksanakan asesmen tergolong cukup. Persentase tertinggi yang menyebabkan guru kesulitan dalam merencanakan asesmen adalah menetapkan tujuan pembelajaran. Sedangkan persentase tertinggi yang menyebabkan guru kesulitan dalam melaksanakan asesmen adalah dalam pelaksanaan asesmen ranah afektif, terutama dalam mengamati aspek sikap dan mengkondisikan pelaksanaan asesmen. Dapat disimpulkan bahwa kesulitan guru IPA SMP se-Kecamatan Labuhan Maringgai dalam merencanakan asesmen yaitu dalam menentukan teknik asesmen dan menentukan bentuk asesmen. Kesulitan dalam melaksanakan asesmen yaitu pada ranah afektif, ranah tersebut tidak dapat diukur karena sikap dan karakter peserta didik sewaktu-waktu dapat berubah.Kata kunci: asesmen, guru IPA, kesulitan, melaksanakan, merencanakan
