The “Strategic Plan for Information and Communications Technology” launched in May 2010 by the Japanese Government advocates the creation of solid contents for digital textbooks to be used in primary and secondary education. However, it does not offer any insight on the role that digital textbooks can play in higher education. In the academic year 2013-14 the Italian language program at the Open Education Center of Waseda University launched two courses that offer students a full set of digital booklets created with iBooks Author as a way to enhance the learning process. This paper uses Rogers’ “diffusion of innovations” theory to investigate the meaning and potential of digital textbooks in higher education and then, using data collected in the first year of the project, it looks at the pros and cons of creating digital textbooks with iBooks Author and at ways to enhance the default “Review” widget to create meaningful and creative drills for language learning. Lastly, the paper also looks ahead at long-term issues and expectations.

The PostPC era offers many exciting possibilities for education. One of these is related to digital textbooks; how they can best be utilized. Our latest interest is combining various interactive functions into a digital textbook that could give readers a learning experience that is as close to a live interaction as possible. In addition, with LMS（Learning Management System）, further class improvement and better individual support to students would be expected. For example, a flipped classroom based on this interactive approach could work much more effectively. Our proposed digital textbook with LMS installed has a seamless, powerful interactivity beyond a classroom. In this paper we will show you the potential of our digital textbook in the PostPC era, and discuss effective ways to use it.

The digital textbooks for elementary schools for learning instruction was published from each company in the 2011 fiscal year. The digital textbooks for junior high schools for learning instruction and the digital textbooks for high schools for learning were published continuously. Various kinds of teaching materials for computers and video materials are integrated. in a digital textbook. In the process of digitization of textbooks, copyright clearance of published material and digital rights management are important problems. Maintenance of the distribution environment according to the increasing data volume is an urgent problem. The contents of a digital textbook reduce a teacher’ s teachingmaterials preparation, and support student’ s understanding. In the first generation of digital textbooks, therefore neither a design nor operativity has gathered, so decision and standardization of a guideline are required. And the special support education which utilized ICT also needs to be considered.

The purpose of this study is to verify the usefulness of a tablet PC-based learning evaluation system through teaching practice in school education. The system was used to evaluate students’ creativity and skill in a class in which they had to control robots through computer programs at technology education. As a result of teaching practice and evaluation，sufficient number of evaluation record of more than 70 has been carried out in one school hour. The results of recording time and lesson structure showed that the learning evaluation system was effective in evaluating practical learning such as measurement and control robots.

This paper aims at verifying similarity of C language programs by using similarity degree of syntax tree and propose a method of converting a C language program to a syntax tree. Firstly, we design the parts of syntax tree that are used to individually represent variable definition, control structure, function call and the expansion of function etc. of C language program. Then, we propose our method to convert the entire of a C language program into a tree graph in XML form. Finally based on our proposed method, we show a convert program to generate XML formed syntax tree for C language programs.
