Title: The Effect of Different Teaching Materials on Students' Affective Domain When Learning Computer Programming in Fundamentals of Information Science and Technology Classes

Authors: Takeshi Hongo

和文題目： 「情報基礎」のプログラミング学習における教材が学習者の情意的側面に与える影響

著者：本郷　健

The purposes of learning computer programming in the fundamentals of information science and technology classes are to acquire knowledge about the function of programing and for students to experience making some simple programs. In this paper, using Japanese LOGO, we compared student learning when using graphics materials (Turtle Graphics), sound materials, control materials, and quantity materials. We investigated the effect of the differences in these materials on students' affective domain and learning progress. We obtained the following results. Different teaching materials cause differences in students' learning progress and the learner's affective domain. The control materials, as compared to other teaching materials, are superior and provide a collaborative learning environment in a natural way. This points out the value of learning programming.

Key words: Information Technology Education, teaching materials development, Japanese LOGO, programing

Title: Gentarou Tanahashi and Craft Education: Tanahashi's Contribution to Craft Education

Authors: Yoshihiko KOIDE and Fumihiko ISHIDA

和文題目：棚橋源太郎と手工教育
　　　　　　〜棚橋の手工教育における活動〜
著者；小出義彦， 石田文彦

We reviewed Gentarou Tanahashi's life works; his research and educational activities, and the status of craft education from 1886 to 1907. We also assessed his contribution to craft education. In the restoration period of craft education, from 1902 to 1916, Gentarou Tanahashi took part in craft education primarily through his writing activity. He first wrote about craft courses in the Shougaku kaku ka kyouju hou zen' [A Compilation of Teaching Methods for Each Elementary School Subject] which was published in 1902. He identified the positioned of craft course in the elementary school curriculum and outlined a tentative plan for the content that should be taught. In 1905, he coauthored Shukou ka kyouju sho' [Teaching Craft Education] with Hidekichi Okayama. This text discussed the history of craft education, teaching methods for craft courses, and its educational value and objectives in Europe, America and Japan,. When he returned after studying abroad in 1909, he introduced European and American craft education. He published books and articles which pointed out the problems with Japanese craft education. He worked as a lecturer in the All Japan Elementary ! ! ! School Teachers' Seminars for Craft Courses held by the Ministry of Education between 1915 and 1916. During his life, he published 4 books and 18 articles about craft education, he developed a theory of craft education, he enlightened others about craft education, and contributed to the restoration of craft courses.

Keywords : restoration period of craft education, Shukou ka kyouju sho, theory of craft education

Title: Morphology of Brittle Fractures in Cemented Carbide Tools as Determined through Simulation Tests of Intermittent Cutting

Authors: Takao YAKOU and Fumiko SUMIDA

題目：断続切削の模擬実験における超硬工具の脆性欠損の形態

著者：八高隆雄，角田文子

To clarify the relationship between brittle fractures in cemented carbide tools and the build up of material on the tool (adhesions) when tools are intermittently used, cyclic impact tests were performed. In these tests, cemented carbide tools K10 and structural carbon steels S25C were used. The location of the brittle fracture was not determined for low life expectancy tools, but in higher life expectancy the fractures propagated around the adhesions. In addition, it was found that the adhesions were deposits of steel which was transported from the material being cut. We also observed three patterns of fractures in the tools.

Key Words: Interrupted Cutting, Impact Test, Brittle Fracture, Tool Life, Surface Adhesion

Title: The Production of a Kerosene Burning Crucible Furnace and a Lesson in Casting Aluminum

Authors: Toshikazu YAMAMOTO and Ryoya MAKINO

和文題目： 灯油バーナーるつぼ炉の製作とアルミニウム鋳造の授業実践

著者： 山本利一，牧野亮哉

A lesson in aluminum casting was conducted in a Junior High School Industrial Arts and Home Making (Gijutsu Katei)course using a kerosene burning crucible furnace. The purpose of this lesson was to produce something by recycling metal articles such as aluminum cans and aluminum engine parts. In order to achieve this goal, we constructed a kerosene burning crucible furnace that met the following criteria: (1) it had to have the capacity to contain the amount of aluminum necessary for casting one class of student's products, in other words, it had to be able to melt approximately forty pieces at one time; (2) it had to be as smaller and portable as possible; (3) it had to be able to heat up to approximately 750C which is the temperature necessary to keep aluminum fluid; (4) is had to burn kerosene as it is an easily obtainable fuel, and it had to prevent sparks from shooting up in the air; (5) it had to heat up in short time. Regarding the casting method, the full mold method was used because it can be done easily by Junior High School students and don't take much time. This lesson may also be useful in environment education since it involves recycling of metalic scrap articles.

Key words: casting, metal working, kerosene burning crucible furnace, full mold method, utilization of waste aluminum cans

Title: Development of a Multi Port I/O Interface Using a Printer-Port and a RS-232C

Authors: Masato Mori, Yutaka Shida, and Nobuyasu Sato

和文題目：プリンタポートとＲＳ−２３２Ｃを利用した多ポート入出力インタフェースの試作

著者：森　正人，志田　寛，佐藤信安

We developed an I/O interface for personal computers and used it as a teaching material when teaching about computer control techniques. By combining a printer port (which is usually installed in a personal computer) with an RS-232C, we were able to produce an interface that has multiple 8 bit I/O ports. We also developed a high speed program for driving the interface which is capable of dealing with a multi-variable control system and rapidly varying signals. We expanded the interface to five ports and created a simple four channel oscilloscope using the personal computer. By doing so we confirmed the effectiveness of this multi-port, high-speed I/O interface.

Key words: interface, printer port, RS-232C, Centronics Interface

Title: Development of a Scale that Measures Students' Emotional Awareness When Making Products in a Middle School Technology Education Class

Authors: Tetsumi UNO, Masashi MATSUURA, and Shigeki ANDOU

和文題目；中学校技術科の製作学習における生徒の情意的意識に関する尺度構成

著者；宇野哲美，松浦正史，安東茂樹

In our opinion, classes that involve students in making products require the assitance of the teacher, and are structured around general knowledge of technology and production techniques. In classes such as these, we think it is not only important to develop the students' knowledge and skills but also their emotional awareness. For this study we developed an instument that measures students' emotional awareness related to making products in technology education classes. We used a questionnaire and analyzed the students' emotional awareness when making products. Using factor analysis we learned that there are three factors. The first factor was a sense of accomplishment. The second factor was preconception about this kind of learning experience. The third factor was basic behavior.

Key words: technology education, emotional awareness, factor analysis
