    近年，問題を解決するために情報技術を適切に活用するための情報セキュリティの重要性は極めて高い。情報セキュリティ人材，専門性に加えて情報セキュリティに造詣の深い人材，いわゆる橋渡し人材の育成は喫緊の課題である。2020年度から本格実施される小学校プログラミング教育においては情報技術を適切に評価・選択・活用できる資質・能力，情報の科学的な理解の育成に高い期待が寄せられている。本研究では情報の科学的な理解の側面から情報セキュリティ育成につながる小学校プログラミング教育実践の開発を行い，小学校で展開するための研修プログラムを構築することを目的とした。 令和3年度では，開発したマルウェアに関するプログラミング教材を小学校の教育現場で展開するための講習会の実践と，パスワードをテーマとした教材開発に取り組んだ。講習会参加者のデータを分析した結果，情報セキュリティの理解に向けて，プログラミングを取り入れた擬似体験に取り組むことが重要であるという意識が高まったこと，また，小学生を対象としたマルウェアに関する指導イメージを持てるようになったことが示された。 パスワードをテーマとした教材開発については，小学生のパスワードに対する意識を高めるために，ビジュアル型プログラミング言語Scratchを用いた教材を開発し，試行的実践を計画した。

    In my collaborative EFL learning environment, the learners could explicitly access syntactic characters of target expression in the context, share the notebook including syntactic character of the expressions with other learners. The learners could formatively and deeply study expressions by using comparison between the uses of target expression, adult FL learners could study target expression based on problem solving approach. In this study, the built-in notebooks has important roles for initial users of my learning environment, therefore, the built-in notebook construction conducted by students studying English Education put priority. As the result, the number of collected expression notebook were 2540(the number of expression type were 1063).

    The purpose of this study is to develop lesson study packages for home economics teachers. These comprise home economics lesson videos and a video sharing system by which the comments of home economics education experts can be viewed in synchronization with the videos. Firstly, we developed VISCO. VISCO is a system by which comments on a video by multiple participants can be shared over the Internet. We then collected videos of home economics lessons given at an elementary schools, junior high schools, and senior high schools and edited them. They were then shared with home economics education experts from teachers colleges and school departments who, using VISCO, made comments on them regarding such things as points of excellence, problems, and advice. These, VISCO and home economics lesson videos, were then packaged as teaching materials and distributed to home economics teachers.

    This research targets the educational practice that teachers feed back comments based on their analysis for each children. It is the purpose of this research to examine an application of text mining to realise supporting their comment writing in such educational practice. While teachers gain experience in writing their comments, unconsciously, they come to use specific words repeatedly in their description. Using text mining, we extract such feature words from comparing their comments between teachers. As a result of experiment on a elementary school teacher, it is suggested that the feature words supports his comment writing.

    We tried to upgrade the performance quality of a class on electromagnetics by introducing tablet-PC-assisted collaborative learning. The first scenario consisted of 5-6 membered groups 2 of which was made collaboratively to solve review task problems, and, in the class, asked to make presentation of the solution process. It took, however, too much time for the groups to prepare for the class, and the other students would not participate in the discussion. Moreover, the teacher had practically to run the class twice with the same theme. Hence a new scenario was designed in which 2 preparatory tasks for the coming class was assigned to 6-8 teams of three members who uploaded their solution plans to the server. In the class the teacher asked the teams assigned each of the tasks to make presentations of their plans, and, guiding comparative discussion along with extensive lectures, could upgrade the performance quality of the class, as well as attaining the goal of the class.

    We have developed a web system to assist collaborative problem solving activities as well as presentation of their outcomes. The system provides a work place in which the members collaborate in solving problems on the network-shared front-faced screen by way of hand writing as well as voice. It also provides varied repertories of materials accompanied by graphical descriptions describing their structures as well as semantic key descriptions to help retrieving the materials. In search for materials of help in pursuing the task concerned, the system allows the learners to select semantic elements from guided menus visually to express their intensions on a map to which the system executes matching with the semantic key descriptions of the materials, thus to discover useful materials. Based on the retrieved materials and their knowledge structure descriptions, the learners are assisted to plan and describe their problem solving processes, and the system guides the learners to make presentation of the final version of their plans and descriptions.

    For assisting autonomous acquisition of expressions of Japanese as second language, we designed and implemented a system as follows : We provide the learners with a group of texts in each of which those expressions belonging to one of the formative layers are mainly used, along with records of the voice reading the texts. The authors or learners edit and place notes to the text positions where such expressions are used as described in the notes of their formats and semantic categories. The system, going back and forth in the layers, retrieves the text positions where the expression specified by the learners are used and displays those text parts with marking the usage and highlighting the text parts in synchronism with voice reproduction and, optionally, mora-wise pitch sequence of the voice. In this way the system allows the learners to compare different use cases of the same expression or those related either in semantics or formats being accompanied by voice sound and promoting learners of speaking by way of displaying prosody. And thus it helps distinguishable usage of expressions in contexts with episodic validation. The system also provides for sentence-wise blank filling composition tasks in the texts and, diagnosing the learners' answers, guides them using the same mechanism as described above to discover their own mistakes. In implementation, providing a collection of prototype expression notebooks in each of which is described the format of an expression with syntactic features and its semantic category, we developed, using XML technologies, assistance of authoring expression notes. We also developed the expression relational map representing nodes each of which corresponds to a prototype expression and the map provides the learners with an environment in which for them to navigate between the nodes related in formats or semantics, being assisted of comparison between the use cases of the expressions. In diagnosis of composition we refined usage of the Lexicalized Tree Adjoining Grammar. Finally we introduced voice recognition engine in order to synchronize highlighting texts with voice reproduction and also to display the mora-wise pitch information.

    In this report, considering the children's learning activities based on Vygotsky's theory of "Zone of Proximal Development", we proposed a model of students' interaction for their knowledge interchanges. Moreover, studying on dynamics of children's learning and development based on the theory of "Legitimate Peripheral Participation", we developed instructional design for teaching and learning of some subjects and "Integrated Study". For the implementation of the above mentioned the concepts and the designs, we developed some systems as cooperative learning environments implemented with Web-DB, which is consisted of server computer-systems for the students' communication and DB system storing learning information of the students. In our learning environment, students can put/remove the tags as the meta-information of their learning information by themselves. Additionally, the client machines can organize/serialize the learning information by using a mechanism implemented with HTML and JavaScript. The Web-DB system implemented with FileMaker and WebCompanion. Also, we prototyped some visualization tools of the students' learning information, and its history and their interaction, and the relationship between the tags. These studies applied our teaching-learning practices in some units of the subjects (ex.a subject of "Integrated Study" in elementary school, national language in elementary school, elementary arithmetics in elementary school, a subject of "Technology and Manufacturing" in junior high school, geography in junior high school). We developed the units and the cooperative learning environment for each unit. In each teaching-learning practice, we developed (electronic) worksheets schema-structured for children's cognition style to the learning contents of the each subjects. Our learning has a scaffolding function for supporting the students' communication with "Connective, Term". Furthermore, we databased the record and the result of analysis of the teaching-learning practice between these two years.
