Abstract

This research is motivated by the low activity of students in receiving lessons in the classroom. This classroom action research aims to improve mathematics learning activities in class VIII SMP Negeri 3 Kubu. The solution to low activity of students conducted by researchers through the Numbered Heads Together (NHT) of cooperative learning model. The research was conducted in three cycles to 32 students. The technique of data collecting is observation by teachers and collaborators. Student activity expressed by categories of high, medium or low, the success of NHT learning models is successful, less successful or unsuccessful. Activity criteria determined by the researchers themselves with 60% of students are actively involved. Activity in this research there are four, namely: 1). Visual activities, 60% 2). Oral activities, 90%, 3). Motor activities, 85%, 4). Writing activities, 100%. Thus the NHT learning models successfully increased student activity. Keywords: Numbered Heads Together, student activity, circle

Abstract

Problems in learning introductory computer science which need urgent solution is the problem related with the students learning actinevess. Along with the approach of problem posing, problem solving efforts above got the right momentum. Learning approach used in this research is problem posing approach. The purpose of the research is to increase students? learning activeness. This research activity involves two lecturers and 21 students in course of introduction of computer science at semester 4 academic year of 2015/2016. The data collected using the students activity sheet and analyzed in qualitative descriptive. Based on the results of data analysis it is known that the use of the problem posing approach can raise average students learning on the activeness of cycle 1 that included in the category of low and at cycle 2 is included in the category of middle. It means an increase in students? learning activeness after organized research activities. Keywords: learning activeness, students creativity, problem posing approach

Abstract

This paper describes the results of learning physics that begins with the complex questions that require integration of multiple knowledge to resolve the question. In the learning process, students were trained to plan for a settlement of the problem by first identifying the required amount of physical quantities. This learning guided students to learn according to their needs in solving the problem, in this case using a top down approach to processing. This learning involved student’s assimilation and accommodation in planning and solving problem involving both, the students will be motivated to participate in the learning process. Physics student learning outcomes obtained after following study at the high category, which showed that not only motivated to follow the lesson, but also they able to achieve a high score   Keywords: top down approach, physics achievement

Abstract

The purpose of physics learning at the school level is directed to develop the students’ thinking skill. This study aimed to improve the students’ critical thinking skill and students’ problem solving skill through aPBL (authenthic Problem Based Learning) learning. This study used classroom action research designed by Kemmis & Mc Taggart with the stages; problem identification, action planning, action, observation, and reflection. The research data were obtained in the form of the data of students’ problem-solving skill and critical thinking. The data in this research were analyzed qualitatively and quantitatively. The results showed that the application of aPBL (authentic Problem Based Learning) could  improve the students' critical thinking skill and  students’ problem solving skill. This improvement could be seen from the average score of critical thinking test and problem solving skill test that had been carried out. Keywords: aPBL, thinking skill, physics

Abstract

Laboratory activities are important of science learning at any level. At the elementary school lab work needs to be done in the context of daily life in order to training scientific literacy. This study aims to determine how the teacher's perspective on science teaching in primary schools in Sukabumi, West Java in the academic year 2015/2016. Research methods such as survey, data analysis quantitatively and qualitatively. Data collection  used is a kuosioner sheet and interview guides to explore the teacher's perspective grade 4 and 5 primary school in implementing and understanding the context-based practicum. The results  showed all the teachers (100%) stated the laboratory activities is important to be implemented, but most of the teachers (75%) stated the laboratory activities difficult to implemented. Teachers argued do not understand the practicum as an activity that can be done simply based on the context of everyday life in an effort to train science literacy (97%). The results of the elementary teacher's perspective is able to provide precise information about the condition of learning science as a material improvement regarding practical learning becomes more meaningful. Keywords: practical laboratory, context, Scientific Literacy

Abstract

The adsorption of metal ion Pb(II) by croton leaf powder through the activation of hydrochloric acid (HCl) or chemical methods has been researched. The research aimed to determine the optimum condition of croton leaf powder as adsorbent by variation of contacting time (30, 60, 90 and 120 minutes) and the difference in mass of adsorbent (1; 2; 3 and 4 grams ). This research began with downsizing the size of croton leafs become to 100 mesh, then was performed chemical activation by soaking the croton leaf powder with 2 N HCl. The adsorption was conducted by contacting the adsorbent with a solution of the sample based on contacting time and mass of adsorbent, then analyzed by Atomic Absorption Spectrophotometer (AAS). The result showed that the optimum condition of adsorption was achieved at 4 grams adsorbent by contacting time in the 60 minutes with Pb(II) adsorbed 1,76 mg/L or 35,2 %. Based on this findings, we concluded that the increase in mass of adsorbent increased the adsorption power of metal ion Pb(II) by optimum contacting time. Keywords: adsorption, croton leaf powder, metal ion Pb(II)

Abstract

This research was conducted to reveal the science process skills of pre-service physics teacher. There were 241 students (64 men and 177 women) were given the science process skills test. Overall average science process skills score of students at 48.88 with a low category. There are seven aspects of the science process skills were revealed. The average score of predicting 41.55; classifying 41.76; interpreting data 49.37; hypothesize 49.48; plan experiments 50.26; observing 50.34 and apply concepts 59.43. Science process skills of male did not differ significantly with female (sig. 0.717> 0.05). The physic education courses need to improve science process skills of students. Keywords: science process skills, gender
