Abstract

Praktikum yang dilakukan sejauh ini memang sudah memiliki keterampilan proses sains untuk dinilai. Namun, penilaian yang dilakukan belum maksimal. Mahasiswa masih sangat bergantung pada koordinator praktikum, sehingga keterampilan proses sains yang dimiliki mahasiswa tidak berkembang. Pada hakikatnya keterampilan proses sains tersebut dapat meningkatkan hasil belajar. Penelitian ini bertujuan untuk mengetahui apakah ada korelasi antara keterampilan proses sains dengan hasil belajar mahasiswa pada praktikum sifat koligatif larutan. Metode penelitian ini adalah penelitian deskriptif kuantitatif. Penelitian ini dilaksanakan di kampus IKIP Mataram. Subjek pada penelitian ini adalah mahasiswa semester genap program studi pendidikan kimia, matematika dan biologi yang berjumlah 138 orang yang memprogramkan mata kuliah kimia dasar II Tahun Pelajaran 2013/2014. . Instrumen penelitian yang digunakan dalam pengumpulan data adalah lembar observasi keterampilan proses sains dan Lembar soal tes hasil belajar. Teknik analisa data untuk menghitung koefisen korelasi keterampilan proses sains dengan hasil belajar digunakan  rumus pearson korelasi product moment. Hasil penelitian menunjukan bahwa keterampilan proses sains mahasiswa dalam praktikum sifat koligatif larutan memiliki korelasi positif dengan hasil belajar. Hal ini ditunjukkan oleh r sebesar 0,2897 menurut korelasi pearson product moment dan r 0,1676 dengan taraf signifikan 5%.

Abstract

Acid-base is one of topics considered difficult by students. This concept is broad,  varied. Despite it is very closely related to everyday life, its application was still lacking. The development of teaching materials in the form of a module was deemed to be a solution to this problem. The aim of this research was to develop CTL module with green chemistry orientation in acid-base subject material to improve science literacy of students. This study was developed ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The developed product was validated by three experts, a practitioner and ten high school students. Data were analyzed using percentage formula. Qualitative data in the form of comments and suggestions from validator were used as consideration to revise the developed module.Tthe effectivity of the module was assessed using N-gain test. Based on validation results, we obtained average of 86,5%, 97%, 88%, and 94,58%. Effectivity evaluation using N-gain test shows an average score of 0,5 with moderate category. Result of student attitudes towards science data has an average score of 74% with good qualifications. It was concluded that developed module prototype is effective for acid-base topic, and most likely for other topics in learning process and growing student science literacy.

Abstract

The aims of this study were to produce android base learning media inelements periodic system subject material and to evaluate its eligibility,pratical, and effectiveness to grow student science litaracy. In form ofResearch and Development, this study was carried out by ADDIE Model(Analysis, Design, Development, Implementation and evaluation). Data wascollected by respons questionnaire, validaty questionnaire and scienceliteracy test. Data was analyzed by eligiblepercentage, eligiblecategorization, and N-gain test. Study result showed that content validity andmedia design validity was very eleigible with 81.11% and 83.97% ofeligibility respectively. Practicioner and student respon was very eligible with80.95 % and 89.02 % of eligibility respectively. Effectivity trial obtained 0.62of N-gain with moderate category. It can be concluded that android baselearning media was very eligible to applied for students science literacygrowth on elements periodic system learning effectively.

Abstract

The aim of this research was to evaluate correlation between students science process skill and learning achievement. In form of correlation research, this research was conducted at Chemestry Laboratory of IKIP Mataram in time of 2015-2018. Subject of this researh consists of 138 students who got basic II chemistry practice. Instrument of this research was guestionnaire and test. With 98,22% of validity, the instrument was highly eligible to used in data collecting. The data analyzed by product moment. The data analysis showed that rtest (0,1743) higher than rtable (0,1676). The research showed that there is significant correlation betwen science process skills and students learning achievement.

Abstract

The purpose of this study was: (1) determine differences in metacognitive awareness and cognitive abilities of students who learned with PBL and conventional strategies, (2) determine differences in metacognitive awareness, science process skills, and cognitive abilities among students with divergent thinking and character convergent strategies are learned with PBL. This study uses three different kinds of design that is descriptive research design, quasi-experimental design, and pre-experimental design to answer the research objectives numbered one through three in a row. The instrument used in this study were: (1) questionnaire divergent thinking and convergent character, (2) metacognitive awareness questionnaire, (3) observation sheets science process skills, and (4) tests of cognitive ability. Data were analyzed by inferential statistics. The results showed that: (1) there is no difference in metacognitive awareness and cognitive skills of students with learning strategies derived from PBL and conventional strategies, (2) there are no differences in metacognitive awareness and cognitive abilities among students divergent and convergent. Science process skills students better than the divergent-convergent.
