Assessment literacy is fundamental for teacher because it is related to decision making task which will then give impact to students’ future. Assessment literacy influences teachers’ routine practice of assessment in classroom. Without knowing the current assessment literacy among teachers, it is difficult to monitor or give relevant reinforcement to improve the quality of assessment practice. Therefore, this study is aimed to figure out the profile of science teachers’ assessment literacy through a 54-items questionnaire developed from Assessment Literacy Standard (ALS) from Michigan Assessment Consortium. The questionnaire consists of selected choice response and open-ended question. Fifteen secondary school science teachers voluntarily participated in this study which came from 9 school in West Sumatra. Then, data was analyzed with descriptive analysis technique. Our findings revealed that while most teachers agreed with the ideal condition of assessment practice stated in the questionnaire, most are not sure when it comes to analyzing data from assessment with statistic tools or taking the use of assessment result further to improve learning quality for both students and teacher themselves. Implication of these findings on the preparation program of science student teacher in Universitas Negeri Padang was discussed further.

Salah satu tujuan dari pembelajaran IPA adalah untuk mengenali gejala alam agar dapat hidup berdampingan dengan alam tanpa kendala berarti. Krisis air bersih adalah salah satu tanda bahwa ada ketidakcocokan antara gaya hidup manusia dengan kondisi alam. Bererapa daerah di Indonesia telah mulai mengalami krisis air bersih, akibat musim kemarau yang berlangsung lama. Meski Indonesia merupakan negara kepulauan yang dikelilingi laut, dampak perubahan iklim dan bencana kebakaran hutan dan lahan yang meningkat dalam lima tahun terakhir turut menjadi faktor dibalik krisis air bersih. Khusus untuk wilayah kota Padang, sebagai salah satu wilayah yang rentan terhadap bencana gempa, banjir, dan tsunami, pengetahuan dan keterampilan untuk mengatasi masalah air bersih merupakan keharusan untuk dimiliki setiap warga. Pelatihan ini bertujuan untuk memperkenalkan salah satu cara memperoleh air bersih dengan membuat kit penyaringan air konvensional menggunakan alat dan bahan yang murah dan mudah diperoleh di sekitar lingkungan tempat tinggal. Melalui pelatihan ini, diharapkan peserta lebih siap menghadapi berbagai situasi dimana air bersih sulit didapat dan mampu menerapkan keterampilan yang diperoleh untuk membantu masyarakat di lingkungan sekitar. Selain itu, melalui pelatihan ini juga diharapkan kesadaran peserta akan pentingnya menjaga kualitas air melalui mencgah terjadinya pencemaran juga meningkat.

Discovery Learning model is one of the learning model that can be used to increase students cognitif ability. The aim of this research is to analyze the external factors of Discovery Learning models that effect the student cognitive abilities, from several research articles. This is an expost facto research with descriptive qualitative approach and documentation as the teachnique to collect the data. The sample used in this research were articles (at least 3) relating to the used of the Discovery Learning model on students' cognitive abilities with a minimum journal level of Q3. The data analysis technique consists of several steps, there were, data reduction, data display, and verification. The result shows there were several external factors that affect the students' cognitive abilities in the application of the Discovery Learning learning model, such as the learning environment, learning media, and providing stimulus.

On teaching and learning process, educators are required to be able to create situations that allow students to be active and creative. One of the efforts to integrate science with ethnoscience in the form of teaching materials is one of the breakthroughs in the development of teaching materials. The observation in SMPN 11 Padang shows that still used teaching materials in the form of LKPD which colorless and newspaper base paper. This made students' interest in learning are decline. Based on the observation result, the researcher wants to do research that the aim is to produce science teaching material integrated ethnoscience that valid and practical to use. The type of research used is Research and Development (R&D). The research method used in the 3 stages of the 4-D (Four-D model), namely defines, design, and development. Teaching materials are valid when the eligibility criteria for content, language, presentation, and graphics are reached by the validator's expert. Teaching materials are practical when the criteria for ease of use, time efficiency, and benefits have been assessed by teachers and students. The validity and practicality values obtained through instruments in the form of interview sheets, validity questionnaires, and practicality questionnaires. The results showed that the integrated ethnoscience science teaching materials can be used with valid and practical categories. © Department of Science Education, Universitas Negeri Padang Keywords: Science Teaching Materials, Webbed, Ethnoscience, 4-D Model.

The background of this research was the results of the researcher's observations on 8th grade students of SMPN 14 Padang. Based on the results of observations, information was obtained that teachers had previously implemented the PjBL learning model but never had implemented the STEM approach, and teachers had never combined the learning model with the STEM approach. The purpose this research was to examine the effect of the PjBL-STEM learning model on students' cognitive skill regarding substances and their changes subject. The type of research used was Quasi Experimental, design, using a Posttest Control Group Design. This research used two classes, there were experimental and the control class. The experimental class uses the PjBL-STEM learning model, while the control class used a conventional approach learning model. Sampling in this study was carried out using a purposive sampling technique, based on almost the similliary average daily test scores. The instrument of this research were multiple choice test with 20 questions. The results of data analysis show that the cognitive skill of students in the experimental class are higher than those in the control class. The used of the PjBL-STEM learning model makes a good difference in students' cognitive abilities. The results of hypothesis testing based on posttest data obtained from the two sample classes showed that, H0 was rejected and H1 was accepted, so it can be interpreted that there is a difference in the average cognitive abilities of students in the experimental class and the control class. There is an effect of the application of the PjBL-STEM learning model on the students’ cognitive skill on substance material and its changes subject.

Low student communication skills have been the cause of this research, which had an impact on learning outcomes because there had not been training on students' communication skills through the application of appropriate learning models. The learning process, which still uses conventional learning models, namely group discussions, has not made each student active and responsible for group assignments and has not trained communication skills in scientific arguments. Therefore, an appropriate learning model is needed, one of which is the Numbered Head Together (NHT) type cooperative learning model. The aim of the research is to determine the effect of implementing the NHT type cooperative learning model on the communication skills of SMPN 3 Tebo students. The research uses a Quasi-Experimental type of research with a Nonequivalent Control Group Design. The research began with a pretest in the experimental class and control class, then treatment was given to the experimental class, and at the end of the learning process, a posttest was given to both classes. Samples were taken using purposive sampling technique. The test instrument consists of 13 description questions. Data were analyzed using Microsoft Excel to carry out prerequisite tests and hypothesis tests on overall communication skills and each ability indicator. The results of the research showed that there was an increase in students' overall communication skills between before and after treatment. Through the Mann Whitney test with Zcount -5.32 and Ztabel 1.96 with the criterion that H0 is accepted if –Ztabel ≤ Zcount ≤ Ztabel, then Zcount -5.32 < -Ztabel -1.96, then H0 is rejected, and H1 is accepted. It can be concluded that there is a significant influence of implementing the Numbered Head Together type learning model on the communication skills of students at SMP Negeri 3 Tebo Regency.
