  • This study was to compare 'experiment' presentation types of middle school science textbooks of Korea, Japan, and China and to draw some implication for the improvement of Korean science textbooks. It analyzed the experiments from the unit 'Light' of science textbooks which is common content in all three different science textbooks. The researchers analyzed the experiments with two questions. First, how is the experiment organized? Second, what role does each element of the experiment is playing in the experiment setting? The findings of international comparative analysis of experiment presentation types of middle school science textbooks of three countries were as follows. First, the Korean and Chinese textbooks tended to present the experiments without enough information for the experimental process and method, whereas the Japanese textbook tended to present the experiment with detailed information for the experimental method and process. Second, whereas the Korean and Chinese textbooks tended to have a loosened relationship among pre-experimental content, experiment, after-experiment content, the Japanese textbook tended to have an organic relationship among pre-experimental content, experiment, after-experiment content.

  • The purpose of this study lies in finding out a betterment of ongoing experimental training program in science for the secondary science teachers to increase their training ability more effectively. For this, from 2010 July to September, a preliminary study on secondary science experiment training, questionnaire on the satisfaction of 128 secondary teachers in U metropolitan city with the training program were carried out which were contributive to the preparation of a better plan for the training program to be helpful for the teachers at schools. Following are the study results. First, the class theme should be selected by the teachers who participate in the experiment for the year to raise their training ability for experiment class. Second, the direct activity of the teachers' joining in experiment training for the development of experiment training module, and the demonstration with the developed module-used experiment class need to be included to the program Third, the assessment for the demonstration of experiment attitude, the development process of experiment training module, would be more advisable compared with that for written examination for the teachers joined in the experiment training to concentrate more on the experimental activities and to get richer experiment experience As this study results show, the theme selection, class method and assessment method involved in ongoing experiment training need for betterment for the science teachers to apply it at schools and this improved experiment training program proposed by this study is suitable for that under a condition it has to be modified and supplemented to the distinct features of every city and province.

The Effects of Scientific Experimental Classes Emphasized Small Group Argument Activities on Science Achievement and Scientific Attitudes (소집단 논의활동을 강조한 과학실험수업이 과학성취도 및 과학적 태도에 미치는 효과)

  • The purpose of this study is to examine what effects the experiment class to stress discussion of small groups in scientific experiment class of the elementary school has on scientific achievement and attitude on the science of the students comparing to the usual scientific experiment class. For that purpose, this study has divided 49 students at the 6th grade of the M elementary school in P City into test groups of 24 students and control groups of 25 students. Classes have been progressed by giving sufficient time to the test groups for discussion by each small groups after experiment while by allowing the control groups to finish the experiment with arrangement of the experiment results. Conclusions of this study include: First, the more familiar the experiment materials are and the easier the experiment procedures are to be operated by the students, the more actively the small group discussion activities have been deployed. It shows that the students need a certain level of background knowledge before experiment for vital discussing activities. Second, it is appeared that the test groups given the scientific experiment class stressing small group discussing activity have significantly high scores comparing to the control groups given the existing scientific experiment class. It shows that the small group discussing activities have effects on promoting understanding of the students on the scientific achievement for the scientific experiment class. Third, it is appeared that the test groups given the scientific experiment class stressing small group discussing activity significantly high scores on attitude about the science comparing to the control groups given the existing scientific experiment class. It is considered that the students could have opportunities to compare their own thoughts with others and to have reflective thought to change their thoughts through the small group discussing activity. As shown above, it shows that the experiment class to stress discussing activities is more effective to increase scientific achievement and attitude about the science than the scientific experiment class to get and arrange the experiment results from the existing experiment classes.

  • The purpose of this study was investigated the perceptions and expectations of science gifted elementary students in the laboratory-based science learning. For the purpose of this study, semi-structured interviews were conducted with 20 science gifted elementary students in J city. The question of the interview is constructed with perception and expectation of science gifted elementary students in divided with 4steps of understanding of lesson object, planning experiment, performing experiment and drawing conclusion in laboratory-based science learning and an attitude for science. The interview is progressed per individual and all the content of the interview is recorded. The result of this research is as follows. The science gifted elementary students have a wish for building an assumption and expectation and planning an experiment with discussion more than following the textbook and teacher present. In the step of the experiment, they wanted general more discussion of their own activities rather than teacher's instruction and they wanted teacher's instruction and they wanted teacher's mediation conflicts within small groups and comments for students' experiment results. The science gifted elementary students wish to open a science lab, which man who likes science can go and come freely and to study with friends who have a same interest to make a theme. And from top to bottom they want to test autonomous and ask to salute like a representative experiment of teacher. And they ask to have a chance to test individually and want to see a movie related to an experiment before doing an experiment. Like this, it presents that the scientifically gifted elementary students want to do an experiment what they can, want to have a class which can plan and can do an experiment by themselves through discussion with the unit more than following explanation of a teacher and a textbook without condition.

  • This study aimed to analyze the teachers' cognitions about the primary science textbooks(experiment and observation) used in elementary schools. This study surveyed 211 teachers in Seoul and Gyeonggi province. The data were statistically analyzed by SPSS WIN 10.0. The results of this study are as follows : Most of the teachers showed positive opinions on the directions of the compilation of experiment and observation textbook. Teachers used experiment and observation textbook as summary notes, experiment reports and evaluating methods. The experiment and observation textbooks should be compiled and reorganized in order as follows : Lesson introduction, inquiry activities, and intensive and supplementary activities which are followed by space of description in experiment and observation textbook.
