Abstract

Chemistry learning based on the intertextuality of chemistry demands relationship among chemistry representsation on three levels, which are macrocospic, microscopic, and symbol level with the daily experience of students and the social interaction developed by teachers. Through the research entitled “Pengembangan CD Pembelajaran Interaktif Kimia SMA Berbasis Intertekstualitas sebagai Alternatif Model Pembelajaran”, we will have a learning CD for teachers using competency standard and basic competency; concepts and indicators; the representation of chemistry materials on three levels macroscopic, microscopic, and symbol; learning description; and student work sheet. Before making the learning model, we will execute a standard analysis on the content of KTSP 2006, so we will get the concepts and indicators; potray the learning process of teachers in class and analyse the reference books both text books and hig school books. The data source for this research is the table of according to concept and indicators with competency standard and basic competency; the observation of learning process in class; the analysis table of three levels; hydrolysis materials from text books in high school and university; and the descriptive table of hydrolysis concept learning. The supporting instruments used are quistionaires to know the students expereince and essay texts to know the concept understanding the students have after the learning process. From the standard analysis of the content of KTSP 2006, we have three concepts and eight indicators. The first concept is classifying salt according to the forming compounds with the indicators (1) explain salt coming from strong acid and strong base; (2) explain salt coming from strong acid and weak base; (3) explain salt coming from weak acid and strong base; (4) explaining salt coming from weak acid and weak base. The second concept: hydrolysis is the ions reaction with water molecul producing ion H+ and or OH- with indicators (1) describe salt hydrolysis and (2) explain various kinds of salt hydrolysis. The third concept is salt undergoing hydrolysis can be acid base, or neutral with indicators (1) measure qualitatively the characteristic of acid, base, and neutral of salt by using some indicators and (2) count the ph of hydrolysied salt condensation. The observation result will be recorded on video then transcribed into text and smoothed to be a basic text. After that, we will do propotition degradation to gain global structure. Then, this data will be classified based on the intertextuality of chemistry. From the result of the data analysis we can conclude that the model teacher has not used the learning based on the intertextuality chemistry yet. The learning process of the model teacher is dominated by the symbol level and the social interaction developed by the teacher is not optimal; besides, there is no aspect of daily experience discussed in the learning process. The development of learning model based on intertextuality begins by making hydrolysis material representation in three levels. The compilation of hydrolysis material representation is executed in three steps: analysing high school books and university; making representation device; conducting validation to experts and practitioners; and final revision. In macroscopic level we do demonstration of the condensation and litmus test on soaps, alum, and salt and also the determination pH of the salt by using pH meter. In microscopic level we demonstrate pictures of species salt solutionbefore and after hydrolysis process. Then in symbolic level we demonstrate the formula of salt molecul, ionisation reaction equation and hydrolysis on salt, and mathematic formula in determining the concentration H+ and OH- to count pH and pOH. Later on, we make a description of the learning process equiped with learning media; clarify the demonstrations; present the model in front of experts and practitioners; record it in a learning CD. Meanwhile, the application of the learning CD in class will be conducted in the next research in the second year.Key words: interactive teaching media, intertextuality, teaching model.

Abstract

The aim of this research is to develop practical based biology learning to enhancing science process skill and critical thinking of high school students. Four pre-service teachers involved in this study, in order to develop their performance in innovation and variation of their teaching skills. The method of the study was descriptive and the samples were taken in purposive ways. Results of this study showed that the mean of critical thinking of four schools students that were taught through free inquiry and guided inquiry approach are 70,78, 62,28, 60,53 and 73,17. The mean of science process skill that was taken through observation sheet on concept water pollution is 81,43% and through written test is 73%. On concept nervous system there were significant improvement (α=0.05) between pre-test (25%) and post-test (70,44%). On concept soil and air pollution, there was no significance different between the use of pictorial sheet and ordinary sheet. The mean of students’ achievement on concept water pollution is 80,80; on concept sensory system: 73,69; on concept nervous system: 65,7. But there was no significance different between the use of pictorial sheet (49,74) and ordinary practical sheet (47,6) to enhance students’ achievement on concept soil and air pollution.Key words: practical based biology learning, critical thinking, science process skill

Abstract

The study on teaching and learning of biology class of senior high school was aimed to identify teaching methods and teaching approaches used by teachers in their lesson plans and its implementation in the classroom. The study was conducted in nine senior high schools including three categories of school based on the passing grade of school entrance. Data was collected by documentation study, classroom observation, questioner and interview. Result showed that most of teachers planed their class with four teaching approaches and six teaching methods. The four teaching approaches were conceptual approach, process skill approach, inquiry, and environmental approach where as the six teaching methods were speech, discussion, question and answer, demonstration, experiment, and assignment. In the reality there was a gap between lesson plan and the teaching practice in the classroom. Although teacher planed their lesson using several teaching approaches the instructional systems delivered by teachers in the classroom were more conceptual and were conducted to give the students more subject matter. This type of teaching and learning was categorized by students as a common teaching and was disliked by some students. The comfort of the biology class sensing by student was due to the content of the subject matter which is very close to the human life rather than by the instructional systems delivered by teacher. Key words: teaching methods, teaching approaches, instructional system, biology class, senior high school

Abstract

We conducted a research about communication skill of secondary biology student in Arthropode classification using phenetic method. Data were obtained from written report and oral presentation. There were five indicators used to analyze communication skill in oral presentation, which included their ability to express opinion themselves and hearing the opinion from other, their ability to master the concept to be presented, their ability to communicate of results systematically and clearly, their ability to question, and their ability to answer. Five indicators used in written report were their ability to choose informative character to build fenogram, their ability to undergo step by step, resulted phenogram, their ability to interpret the results, and their ability to make a report. Results showed that communication skill in oral were good enough (63.75%), but low (56.25%) in written. Based on interview, however, students felt comfortable when teacher used the phenetic method to understand classification of Arthropode. This method has markedly stimulated the students to study actively in the classroom.Keywords: arthropode, communication skill, classification, phenetic method,

Abstract

Teaching and learning mathematics should provide opportunity to student to express, explain, and give reason regarding what they are thinking. In addition, teaching and learning mathematics should make student active, creative, efective, meaningful, and joyful. Students are able to think accurately and communicate properly. These are relevant to the essence of teaching and learning mathematics, mathematical thinking and mathematical communication. By teaching and learning matematics student is supported to catch the idea of concepts, rules, and principles of mathematics, and then revoicing all of them. Even they should be able to defence what they assume as rightness argumentatively (mathematical argumentation or mathematical reasoning). Even though mathematical argumentation is one of important mathematical competences, but it has to make student to proportionaly master. However, mathematical argumentation is mathematical creativity with in tolerances to get the real meaning of learning mathematics. Teaching and learning mathematics can use to (i) highlight ideas that have come directly from students; (ii) help develop students’ understanding that are implicit in those ideas; (iii) negotiate meaning with students, and (iv) add new ideas, or move discussion in another direction.Key words: mathematical argumentation, thinking, communication, express, explain, reason.

Abstract

This study investigates the effect of computer animation on assessment of conceptual understanding in refraction phenomena. An instrument was developed by replacing static pictures and descriptions of ray motion on refraction phenomena with computer animations, a commonly used pencil and paper test. Both quantitative and qualitative data were collected. The animated and static versions of the test were given to students and the results were statistically analyzed. The questionnaire was also conducted to provide the student responses about using of animated version test on assessment of conceptual understanding in refraction phenomena. The results suggest that the use of the animation version of the test can be improving score of the conceptual understanding test in refraction phenomena. In general, students had a better understanding of the intent of the question when viewing an animation and gave an answer that was more indicative of their actual understanding, as reflected in the response of the questionnaire.Keywords: animation version test, conceptual understanding test, refraction phenomena
