Abstract

The in vitro effect of gossypol on the small intestinal contractility of Swiss Webster mice have been examined. Thirty six sexually mature male mice with body weights of 30,5-36,5 g. were used and the tested concentrations of gossypol were 5, 7.5, and 10 ppm. Segments of the small intestine such as: duodenum, jejunum and ileum were isolated and immersed in Tyrode solution at 37 oC. The contractions of these organs were measured and recorded using a myograph and physiograph. As control, the contractions of these organs were recorded in Tyrode solution for 360 seconds. The solution was then replaced by gossypol-Tyrode solution and the contractions were recorded again for the next 360 seconds. The results showed that gossypol increased shortly and followed by gradual decreases of tension in all small intestinal segments. Gossypol also lowered the frequency of the intestinal contractions when compared with control. The strongest action of gossypol was found when the intestines were treated in 10 ppm, compared to the action of those treated with 7.5 ppm and 5 ppm. It is assumed that gossypol impaired peristaltic movements of the intestines and thus decreased digestibility of mice.

Abstract

This paper aims at describing teaching and learning activities in chemistry lesson through environmental-based (contextual-based)  experiments that are viewed from the perspective of Islam. Islam teaches its followers to study their environment in order to find solution for many problems. One of the problems posed by chemistry teachers with regards to conducting chemistry experiments is the lack of laboratory equipments. In fact, if environment has been studied well, Islam has provided anything we need including the need to conduct chemistry experiment. Verses in Quran, especially al-Baqarah: 185, an-Nisa: 28, al-Hajj: 78, and Hud: 61 implied that our environment provides more than enough for us to do experiments. The problem of not doing the experiments was that because teachers are not studying their environment well enough. This paper describes some ideas in which environment helps chemistry teachers to be able to conduct chemistry experiments without losing the chemistry concept. DOI: 10.15408/tjems.v1i2.1267

Abstract

AbstractThe development of competency assessments that measure 21st century competencies is critical for improving the quality of education. The purpose of this research is to describe a framework and prototype for assessing Math and Science or Math-Sci competency skills in the twenty-first century. The method of development research employed in this study is based on the Akker framework, which entails preliminary research, prototyping, design, and development in a paper and pencil test format. The equipment of the investigation included observation sheets, questionnaires, and tests. This study results in a conceptual framework for the instrument and a verified prototype of the Math-Sci competence evaluation. The Math-Sci competence evaluation is conceptualized around thematic, interdisciplinary questions that integrate three (three) subjects, namely Science (Biology-Physics) and Mathematics, in an Islamic context. Math-Sci, using the ladder analogy (monodisciplinary, interdisciplinary 1, and interdisciplinary 2) to rank students' competency, relates to the thought process of Bloom's taxonomy, the context, and the complexity of the topic. The instrument created was deemed valid and practicable based on the results of expert validation. The development of the Math-Sci competence assessment instrument was the first step toward strengthening assessment for learning and assisting in the improvement of learning through the presentation of integrated contextual problems. AbstrakPengembangan asesmen kompetensi yang membekalkan kecakapan abad 21 sangat urgent untuk memperbaiki proses pembelajaran di sekolah.

Metode penelitian pengembangan yang digunakan dalam penelitian ini mengacu pada framework Akker yang meliputi penelitian pendahuluan, prototipe yang meliputi desain, dan pengembangan dalam format paper and pencil test. Instrumen penelitian berupa lembar observasi, angket, dan tes. Hasil penelitian diperoleh kerangka konseptual instrumen dan prototipe asesmen kompetensi Math-Sci yang telah divalidasi melalui expert judgment. Kerangka konseptual asesmen kompetensi Math-Sci berupa soal-soal tematik, interdisipliner yang memadukan 3 (tiga) disiplin ilmu yakni IPA (Biologi-Fisika) dan Matematika pada konteks keIslaman. Math-Sci dengan analogi titian anak tangga (monodisiplin, interdisiplin 1, dan  interdisiplin 2) yang mengukur kompetensi peserta didik secara hierarki mengacu pada proses berpikir taksonomi Bloom, konteks dan kompleksitas masalah. Hasil validasi pakar diperoleh instrumen soal yang dikembangkan valid dan layak. Pengembangan instrumen asesmen kompetensi Math-Sci merupakan langkah awal upaya menguatkan asesmen for learning, membantu memperbaiki pembelajaran, bersifat inovatif dengan menghadirkan permasalahan kontekstual integratif.  How to Cite: Zulfiani, Suwarna, I.P., Suwarna, Muin, A.
