Abstract

The research aims to develop a learning evaluation tool on Newton's Law material based on a four-level test to determine the quality of the instrument and the ability of the metacognition profile in students. The research design uses R&D (Research and Development) with the latest 4-D learning development model (define, design, develop, disseminate). The sampling experience was carried out at 3 state senior high schools in the ex-residency of Pati, namely SMAN 1 Juwana, SMAN 1 Kudus, and SMAN 1 Rembang with a total of 185 students as respondents. The results of the analysis at the small-scale test development stage resulted in an average validity of 87.26% by experts, a reliability value of 0.68 in the small-scale trial stage, and 0.74 in the large-scale trial. The difference power test on the small-scale examiner resulted in 16.67% of the total questions that could not be used for the next major testing stage. The results showed that for each indicator of metacognition abilities, 31% of students 'factual abilities were in the understanding category, 28% of students' conceptual abilities were categorized as understanding, 32% of students 'conceptual abilities were categorized as understanding, 14% of students' planning abilities were in the understanding category, In the research results for the ability indicator as high as 17%, and the evaluation indicator as much as 6% of students were categorized as understanding. Students in the category of understanding have the highest on the indicator of factual ability, while the lowest is on the indicator of evaluation ability. The research resulted that the four-tier test evaluation tool was feasible to be applied in high schools to be able to explore the profile of students' metacognitive abilities.

Abstract

Telah dilakukan suatu penelitian tentang analisis struktur bawah permukaan di daerah Trangkil, Gunung Pati, Semarang, Jawa Tengah berdasarkan data gaya berat. Latar belakang dari penelitian ini adalah bahwa daerah Trangkil merupakan daerah yang telah dinyatakan rawan longsor oleh Direktorat Geologi Tata Lingkungan. Penetapan daerah Trangkil sebagai daerah rawan longsor dinyatakan setelah pada tanggal 23 Januari 2014 daerah tersebut mengalami bencana longsor besar yang menyebabkan beberapa rumah rusak parah. Oleh karena itu, perlu dilakukan penelitian geoteknik yang memanfaatkan metode gravitasi atau gaya berat, sehingga struktur bawah permukaan daerah trangkil dapat diketahui. Metode yang digunakan dalam penelitian ini adalah metode gaya berat. Metode gaya berat adalah salah satu metode geofisika yang menggunakan disribusi parameter percepatan gaya berat di permukaan bumi. Faktor-faktor yang mempengaruhi nilai variasi percepatan gaya berat bumi antara lain densitas batuan (kerapatan massa), kondisi morfologi, pasang surut, udara bebas, bentuk bumi dan lain-lain. Variasi densitas bawah permukaan tanah adalah faktor yang sangat berpengaruh dalam penentuan penyebaran anomaly gaya berat secara geofisika. Pengumpulan data dilakukan dengan menggunakan alat Gravity Meter, yang selanjutnya dilakukan pengolahan data meliputi proses koreksi yaitu tahapan pengolahan data gaya berat hasil observasi di lapangan. Hasil Simple Bougier Anomaly (SBA) untuk anomaly pada daerah penelitian berkisar di antara 0,5 mGal – 7,5 mGal. Hasil Complete Bougier Anomaly (CBA) untuk anomaly pada daerah penelitian berkisar di antara 0,5 mGal – 7,5 mGal.

Abstract

This research aimed to develop a learning evaluation instrument on Newton's Law Materials using a four-tier test with a metacognitive perspective to identify students' thinking abilities from metacognition and students' misconceptions. The research employed the R&D (Research and Development) design with a 4-D development model (define, design, develop, and disseminate). The instrument was constructed by developing twelve questions. There were ten valid and reliable questions with good quality parameters (difficulty level and differentiating power). The researchers analyzed the four-tier test instrument with a metacognitive perspective approach using item difficulty level analysis, item discriminatory analysis, test reliability analysis, and expert validity testing. This research involved 30 participants in the small-scale test and 250 participants in the large-scale trial. The test results showed that the ten questions could identify students' thinking abilities from the perspective of metacognition and misconceptions on Newton's Law material. The findings of the large-scale test showed that students' thinking skills were mapped into high, medium, and low categories. Students' misconceptions were also mapped on each indicator of the questions compiled. Based on the mapping result, the highest students' misconceptions were found in the aspect of the metacognitive experience, with an average of 76 percent of students experiencing misconceptions.
