Abstract:
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.

Abstract:
This study aims to look at the media, learning resources, and teaching materials used by physics teachers of high school for wave material. In accordance with the learning needs of 21st century, the media used must be IT-based. To see how important the use of IT media in learning process is conducted research with descriptive analysis research type. The data of this study were obtained with interview guidelines, directly with teachers distributing questionnaires the availability of media, learning resources, and teaching materials in schools to respondents, namely teachers in seven schools, and distributing questionnaires for learning resources and teaching materials consisting on identity and indicators of aspects reviewed in learning resources and teaching materials. Based on results of data acquisition, it was found that teacher has not used much media in the learning process. In fact, for 21st century learning, IT-based learning media are needed so students can practice 4C skills (critical thinking, creativity, communication, and collaboration).

Abstract:
Material inheritance is one of the materials in science subjects that students are less interested in. This can be seen from the low motivation of students in learning. In addition, in this material students are required to use a variety of terms that are new to them, using letter symbols to indicate characteristic or genes in order to be able to cross and be able to determine the choice of genotypes and phenotypes resulting from these crosses. The purpose of this study was to increase the activities of students who use chess boards on material inheritance. This research is a Classroom Action Research (CAR) which was conducted in two cycles. The subjects of this study were 30 students in class IXa. The results of this study indicate the use of chessboard media on class nature inheritance material in class IXa students at SMPN 4 Solok City can increase student activity. Thus this media can be used in learning to increase student activity on material inheritance.
