Pemanfaatan sistem informasi sebagai penopang organisasi tidak dapat dipungkiri lagi, dimana setiap bagian dari organisasi diharapkan mampu memberikan pelayanan yang cepat dan akurat kepada setiap end user. Salah satu bentuk layanan sistem informasi tersebut adalah Expertise Management System (EMS). EMS dikembangkan di Universitas Negeri Semarang (UNNES) memiliki kemampuan untuk menyajikan data tentang pakar-pakar yang telah dimiliki UNNES kepada end user. Desain EMS melalui tahap prototype (analisis, perancangan, desain sistem, DFD, ERD, dan desain skema database), pemrograman, pengujian dan pemeliharaan. Melalui EMS ini pula, UNNES dapat menawarkan pakar-pakarnya untuk berkolaborasi dalam penelitian maupun kegiatan lainnya, sehingga dengan sendirinya akan memperkuat posisi UNNES di dalam persaingan tingkat regional maupun global.Â

Penelitian ini menggunakan pendekatan Research and Development dengan tujuan untuk memotret penilaian pembelajaran yang sudah ada, mengembangkan instrumen penilaian pembelajaran dan menguji validitas, reliabilitas serta keefektifan produk. Pengembangan instrumen mengacu pada model Borg and Gall (2003). Instrumen ini dirancang untuk mengukur ranah afektif (karakter demokratis) dan ranah kognitif (kemampuan berfikir kritis). Teknik pengumpulan data dengan metode tes, dokumentasi, observasi, wawancara, dan angket. Analisis data pada produk awal divalidasi oleh pakar untuk mendapatkan validitas isi. Selanjutnya, instrumen diujicobakan secara terbatas kepada peserta didik di SMA Negeri 1 Welahan Jepara. Hasil ujicoba instrument kemampuan berfikir kritis diukur validitas dengan rumus product moment. Sedangkan uji reliabilitas menggunakan rumus alpha. Tingkat kesukaran soal dan daya pembeda juga diukur. Pada instrument penilaian karakter demokratis yang diukur adalah validitas dan reliabilitas. Hasil pengukuran menunjukkan instrument penilaian pembelajaran yang dikembangkan valid, reliabel, praktis dan efektif.This study used Research and Development (R&D) whose objective were to highlight the existing learning assessment and to develop a new learning assessment by testing validity and reliability, as well as the effectiveness of the well-developed product. This study referred to Borg and Gall (2003) model. The instrument of this study, that is the developed product, was organized to assess the affective domain (democratic character) and the cognitive domain (critical thinking ability). Additionally, the methods of data collection were using tests, documentation, observation, interviews, and questionnaires. The data analysis of the preliminary product was validated by some experts to obtain the content validity. Afterwards, the well-developed product was only tried out to the students of State Senior High School 1 of Welahan-Jepara. The try out result of critical thinking ability was analyzed by using the formula of âproduct momentâ to measure the validity. Meanwhile, the reliability test was using the formula of âalphaâ. Furthermore, the difficulty level of the items and discrimination power were also measured. Moreover, the instrument of democratic character assessment also measured the validity and reliability. Finally, the resultsof this study showed that the instrument of well-developed learning assessment was valid, reliable, practical, and effective.

Heuristic strategy is one of the mathematics problem solving strategies to gain effective results. This research aimed to analyze the use of the heuristic strategies based on the modification of the Krulik and Rudnik model. This research discovered and classified the studentsâ heuristic strategies which can be used as a basis to provide assistance in the learning. This research was a qualitative research involving 32 students of SMP Muhammadiyah 4 Yogyakarta as its subjects. The research variables are the indicators of the Krulik and Rudnik heuristic models which the students performed including: read and think, explore and plan, select a strategy, find and answer, as well as reflect and extend. The data was taken through questionnaire and interview methods. The result suggested that: 2 students (6.25%) were in the good category as they did all of the heuristic strategies more often; 21 students (65.62%) were in the fair category since they implemented some indicators of the heuristic strategies; and 9 students (28.13%) were in the poor category since they were lack in implementing the heuristic strategies. In all categories, indicator of find and answer was more oftenly done by the students while the indicator of explore and plan was less done.

Itâs difficult for junior high schoolâs teacher to get position and foster their students whoâre still in transition in creative thinking. This study evaluated creative thinking process based on a model of Wallas (2014). Subjects were categorized into upper, middle, and low category after doing creative thinking ability test. The variable is an existence of junior high schoolâs students in solving a mathematics problem. Data were analyzed through classification, data representation, and conclusions. The results showed 1) 23,33% of students only reached preparation stage, called low category, 2) 60% of students reached illumination stage though students take a long time, called middle category, and 3) 16,67% of students have completed up to verification stage, called upper category. By deepening triangulation interview, right students in that category. Students in low and middle category still need assistance when experiencing obstacle in the creative thinking process, while upper category needs of enrichment materials.
