Abstract

This classroom action research aimed to increase students’ answering activity and quality of the answer to questions asked in Strategi Pembelajaran Kimia course. This research was done in two cycles each consisting of planning, action, observation, and reflection phases. Instruments used in this research were observation sheet and questionnaire. Prompting questions had been designed for each meeting. Primary action given was asking prompting questions in learning. Two observers did observation and lecture was recorded with camera. Observation data from observers and camera recording were analyzed descriptively to get percentage of students who answered question before and after prompting was given as well as to get percentage of keywords in the answer given by students. The result showed that students’ answering activity increased after prompting was given. The quality of the answer got better with prompting questions as well. The aid of visual media given in the next cycle showed that students dared to explain concepts they had not been familiar with. Other actions that increased students’ answering activity were time and reward givings. Data from questionnaire distributed at the end of the course showed that students like prompting questions because they could understand the question and concept asked and then find the answer.

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.
