The purpose of this study was to develop a higher order thinking skill (HOTS) based test instrument on salt hydrolysis for senior high school students. The type of research used is Research and Development (R&D) using the Plomp model which consists of three stages, namely Preliminary Research, Prototyping Stage and Assessment Phase. The test instrument was validated by 7 experts, namely 4 chemistry lecturers of FMIPA UNP, and 3 chemistry teachers using a validation questionnaire. The small group trial was carried out by 6 students and the field test was carried out by 26 students of Senior High School number 1 in Padang. The data analysis technique for content validity uses Lawshe's CVR and the construct validity uses the aiken’s formula. The results showed that the instrument developed had good characteristics in terms of logical validity with a content validity index (CVI) of 0.841 and a construct validity of 0.82. The reliability coefficient of 0.89 is very high. The analysis of discriminating power showed 16 items had very good distinguishing quality, 4 items had good distinguishing quality, 4 items had moderate distinguishing quality. The difficulty index for 88% of the questions is categorized as medium. The correlation of the item score with a significant total score was 21 items. The dictator function on all items is effective. The data obtained shows that the test instrument based on higher order thinking skills (HOTS) on salt hydrolysis material for senior high school students is valid and has good item quality.

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.

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.
