JOURNAL FREE ACCESSThis paper describes the development and evaluation of an interactive blackboard software collecting and displaying students' real-time feedback in class. The lack of interaction between teachers and students is one of the most serious educational problems in Japan. In addition, an interactive blackboard is often used as a teaching tool to support a teacher's presentation by means of a computerization of traditional "blackboard" concepts. This study aims to provide students and teacher with the means to interact with each other in real time in a variety of ways. Some of the "blackboard" concepts were used to develop on interactive blackboard software that allowed students to issue real time feedback, comments, ideas and suggestions using either a web browser or a cellular phone. Feedback is displayed on a screen of the blackboard. A class was conducted to evaluate the effectiveness of the system. Results revealed that students evaluated the feedback functions to be effective and the class was interactive when compared with a traditional class.View full abstractDownload PDF (1417K) -

JOURNAL FREE ACCESSIt seems that the importance of having a sense of wonder towards various natural phenomena in children's everyday lives and having opportunities communicating with nature at their infancy is recognized by many early childhood educators, although science education is not identified at present kindergarten in Japan. At kindergarten, it is regarded as important to nurse rich human nature. However, it is rare to take place a practical education with scientific viewpoints. Then, the goal of this research has two points. The first is to analyze the present of the science condition of science education at kindergarten, through investigating about the activities of a kindergarten and many situations involving early childhood education. The second point is to explore the way that should be and views of the science education at kindergarten with deep consideration of an infantile development. The limitation of this research can be count that only two case studies are taken place with different typical education policies, however, I think that this research becomes clear the present conditions of kindergarten. And it also can be shown the possibility of science education at kindergarten. Finally, it is proposed for treating various scientific phenomena for the young children at kindergarten.View full abstractDownload PDF (800K) -

JOURNAL FREE ACCESSThe purpose of this study was to find out problems in conducting practical work for high school physics teachers in Davao, Philippines, and relate them to their background. A pilot case study about one physics teachers and a further case study about 6 physics teachers were conducted. During the case study, observations of physics practical work as conducted by the teachers as well as interviews with them were used for analysis. A lack of manipulative observational skill and interpretative skills of practical work and scientific knowledge were observed. they also confused the skills with others and had difficulty in mastering. Therefore, in science teacher education involving international cooperation, we need to consider these skills and the level of scientific knowledge and provide a description of each skill, individual training to master these skills, and relate the description of skills to their prior skills. The reasons for this may be thought to be that they have insufficient experience for conducting practical work during their pre-service training and that they do not have an opportunity to master those skills in practical work during their in-service teacher education.View full abstractDownload PDF (1070K) -

JOURNAL FREE ACCESSThe purpose of this study is to evaluate the effectiveness of mathematical activities in graphing polar equations. Using hand-held graphing calculators, students observed many graphs of polar equations r=10sin nθ and explored the properties of the graphs. After their explorations, they analyzed the properties and reasoned mathematically about them by themselves. The following results were obtained : (1) Students found various properties of the graphs of polar equations from their mathematical activities. (2) Some students formulated generalizations and evaluated their conjectures about the observed properties. (3) Students learned new contents of polar coordinates in connection with previous knowledge of trigonometric functions. (4) The authors conclude that the graphing calculator is an effective tool for mathematical activities.View full abstractDownload PDF (997K) -

JOURNAL FREE ACCESSA three-day science camp program that gives an introduction through hands-on learning to the basic principles, interpretation and real-world applications of everyday weather information was developed mainly for 7th to 9th grade students. The program includes (1) instruction on the basics of remote sensing and interpretation of satellite images from a geostationary satellite, the most popular type of weather information, (2) instruction on various kinds of weather information obtained via the Internet and usage of such information, (3) atmospheric measurements carried out in a building and on a mountain using atmospheric pressure, temperature and humidity sensors, (4) simple experiments on the atmosphere, and (5) a field trip to a weather office in an airport and a flight operation department of an airline company. The camp has been held three times. Responses of participants to activities, changes in answers given by participants to the same questions asked before and after each camp, and questionnaires filled in by the participants after each camp were examined. The results of the analyses show that the content of the program and level of difficulty of the content are appropriate. Over 60 percent of the participants replied that the atmospheric measurements carried out on a mountain and the field trip were very interesting. These parts of the program were probably rated highly by the participants because the participants were able to actually experience atmospheric pressure and temperature drops with increase in altitude and to actually observe practical applications of weather information.View full abstractDownload PDF (1126K) -

JOURNAL FREE ACCESSIn this paper, we show the ontcome of engineering design education in the electrical engineering department of Kanazawa Technical College. This engineering design education is based on hands-on experience. In this paper we study how to teach electrical knowledge in the electrical experience class. The aim of this course is to promote students' creativity. It consists of the three phases : the first is studying basic electrical theory through electrical experiments ; the second is learning basic sensing technology through making a line traced model vehicle ; and the third is studying advanced electrical theory using a simple handmade instrument. It seems that in the course the students learned to grasp basic electrical theory and engineering design.View full abstractDownload PDF (1040K) -

JOURNAL FREE ACCESSIn a previous paper (Sato et al., 2002), we introduced three physical models which we had constructed to help pupils in understanding general earthquake concepts such as (1) the three-dimensional plate configuration around Japan and its connection with earthquake occurrence, (2) the mechanism of earthquakes along the interface between oceanic and continental plates, and (3) the three-dimensional distribution of earthquakes in and around Japan. These models were respectively named (1) "Why Do Earthquakes Occur?", (2) "The True Character of Earthquakes" and (3) "Where Do Earthquakes Occur?". In the present study, we examine in detail the significance of these physical models by conducting several practical science classes with and without them at a junior high school. Based on a questionnaire conducted after the classes, the pupils seem to feel that each of these models, especially the second one, is very interesting and useful to them. It is also clearly indicated, through statistical tests of examinations given to the pupils after the classes, that teaching about earthquakes with these models is more effective than that without them.View full abstractDownload PDF (1391K) -

JOURNAL FREE ACCESSThe purpose of this survey with a questionnaire is to clear present conditions and problems of handson activities in nature at elementary schools in Hiroshima Prefecture. The result of the survey shows the following ; 1. The important purposes of hands-on activities in nature at elementary schools are to develop students' mind of symbiosis between nature and human beings and scientific thinking to natural objects and phenomena. 2. It is important that the activities which have been hardly carried on are tried and the activities which have often wrestled with in the lower grades are developed more in the upper grades as teachers make use of their interests. We must consider both students' needs and teachers' experience when we examine the content of activities. 3. Considering the content of activities, it's suitable to use many kinds of useful social educational facilities. In order to further activities, we need to establish stronger relationship between teachers, between teachers and specialists, and between teachers and local inhabitants. The present problems are to organize original curriculum in each school as pillar of the activities, to spread the information about the facilities that schools can use, to secure the people who help the activities.View full abstractDownload PDF (1072K)
