<![CDATA[Periodical properties of elements are not a new topic for students in science education department for they have studied this topic previously in senior high school and in General Chemistry course. However, teaching experiences for the past two years in Basic Inorganic Chemistry course revealed that many students still failed to master the expected learning outcomes for this topic. Therefore, this explorative study was conducted to figure out what kind of difficulty that students perceived in learning this topic. One hundred and twelve students in science education department of Universitas Negeri Padang enrolled in Basic Inorganic Chemistry course in the academic year of 2017/2018 were involved as subjects in this study, and data of students? perceived learning difficulties were collected with a questionnaire. Data were analyzed with descriptive statistics technique to map out our findings which will become the fundamental consideration in discussing attempts to overcome students? perceived learning difficulties. Our findings revealed that the sources of students? perceived difficulty came from several factors, namely: the characteristic of content, personal learning style, condition of classroom learning, availability of relevant learning resources and previous learning experiences. Based on these findings, attempts for better learning of periodical properties of elements were suggested.]]>

<![CDATA[Laboratorium activity and experiment related to Dynamic Electricity topic in secondary schools have always been a “scary” thing to science teachers in Indonesia, especially to those with more experience in teaching Biology than Physics. To our surprise, the problem was more related to teacher’s confidence to conduct lab acitivy rather than to the availability of experiment kit in school. Our visit to two schools in Padang revealed that each school has sufficient amout of experiment kit for Electricity but the science teachers were too scared to take students to lab and get nervous when something is not working, or too scared to damage the kit. Therefore, we would like to offer a solution to overcome this problem by intoducing an easy do-it-yourself simpe electricity circuit with potato. The activity is expected to build more confidence in teachers to conduct lab activity and make science learning more fun to the students. Keywords — electric circuits, electricity from potato, school science, simple science experiment, dynamic electricity]]>

<![CDATA[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.]]>

<![CDATA[This study aimed to figure out what kind of learning resources that science students-teacher used at Basic Inorganic Chemistry Course, especially for the topic of Atomic Structure and Periodical Properties of elements, given the fact that they have studied these topics twice: in Chemistry subject at senior high school and in the second semester at the university. The main background of this study was students’ grades at the end of the semester which was still not living up to the expectation. We believed there could be several factors behind this result. However in this study, we focused on one factor: learning resources. A survey was conducted to figure out: 1) what kind of learning resources that students use; and 2) what are the characteristics of learning resources students expect to have to help them in this course. The data was then analyzed with descriptive statistics technique. Our discussion expanded to the existing learning resources that students can access and what we could offer to help narrowing the gap.]]>
