"SMART" is a word to condense a new kind of educational system recently proposed by the Korean government. It signifies an intelligent adaptive learning system to innovate the educational environment, the contents, methodology and assessment. Developing a digital textbook was one of the main strategic goals to drive forward "smart" education. The Korean government expected to finish the development of digital textbooks of science, mathematics, social studies and English by 2013 and to have a field experiment for them in 2014. However, the case of mathematics was postponed for an indefinite period because its draft version was no different from a traditional textbook in its functional aspect. This situation might come from the non-existence of a good authoring tool and an inexperienced sense by developers of the opportunities available with digital textbooks. This paper introduces the main features for developing a digital mathematics textbook for the 12th grade students, which was developed in the environment of Cabri LM as an authoring tool. This paper also looks upon the results of a whole lesson using the textbook in managing the classroom interaction with students.

This study was done to develop a digital textbook for students to use over the internet for maternity nursing practice. The textbook is not only for student nurses, but also for nurse midwives and nurses working in the maternity. The process used was as follows; 1. Existing educational media on maternity nursing were reviewed and examined. 2. Workshops and meetings were held to decide the most appropriate type of presentation. 3. The digital content including text, pictures, audios, and videos were developed using Macromedia Dreamweaver, Adobe Photoshop and Adobe Premier. 4.Revisions were made recursively as the content was previewed and implemented over the internet by professionals and the end-users. 5. A database of members and a web survey module were developed and posted. The clinical implication of a digital textbook over the internet is the possibility of using it to educate many student nurses throughout the country and to disseminate the content for whoever needs it in practice settings and facilities. Another implication is that this site stressed interactivity by developing member database and web survey. In conclusion, the study found this first trial of digital textbook to be a unique educational media for nursing skills practice. Further refinement of this media is strongly recommended.

The 4th industrial revolution is coming. In order to prepare for the new learning environment with it, we may need digital mathematics textbooks that fully utilize all possible technologies. So various attempts have been made in elementary and middle school mathematics education. However, despite the importance of higher mathematics, we haven't seen a best possible math digital textbooks yet in Korea. In this paper, we introduce our new model of interactive math digital textbook about Linear Algebra/ Calculus/ Differential Equations/ Statistics/ Engineering Math. Especially, this manuscript focuses on our experience of using digital contents and interactive labs for developing a new model for linear algebra digital textbook. We introduce our works on linear algebra digital textbooks which include pdf e-book, web contents, video clips of lectures, interactive lab. Using this linear algebra digital textbook, students can freely use any mobile devices to access diverse learning materials, lessons, and hands-on exercises without any limitations. Also, times saved in the computation, coding, and typing process can be used to have more discussions for deeper understanding of mathematical concepts. This type of linear algebra digital textbook, which contains all interactive free cyber-lab with codes and all lectures for each sections, can be considered as a new model for the next generation of math digital textbook.

This study is the design and implementation of digital textbooks for elementary school computer education based on smart phone. It suggests how to cultivate self-directed learning ability depending on the level and selection of individuals by maximizing on interaction as advantage of digital textbooks. As the content of the digital textbooks, this study used Excel's charting capabilities. As a result of the evaluation of elementary learners having a implemented digital textbook, execution time of creating a chart is reduced in comparison with paper-based textbook user group.

The digital textbook project which embarked by the Ministry of Education, Science and Technology has focused on experiments and practices from the school designated by the government. However the previous research about digital textbook provides static interaction models and teaching-learning models analogous to web-based learning based desktop PC even the framework of the digital textbook is based of Tablet PC. This paper provides learning and teaching models for next generation digital textbook which based digital inking techinques for sketcth interface and AR(augmented reality) interactions between teacher and learner. The proposed method of this paper is applied to educational contents and we found positive effect which is supported by statistical experiments. The results of this study in the future and the future development of digital textbooks in effect will be an effective development plan.

The PATROL instructional model only uses digital textbooks. PATROL is an acronym for Planning, Action, Tracking, Recommending, Ordering, and Leading. Teachers have a difficult time using current digital textbooks to determine how much time students spend using course materials. This is because current digital textbooks can only show the content of paper textbooks and display additional multimedia materials. In this study, digital textbook functions were designed based on the PATROL model in order to analyze students' learning situations, diagnose problems, and offer solutions. Digital textbook are based on learning analytics named SEE-PAD. SEE-PAD is composed of the following: Social network analysis; Evaluation and assEssment analysis; Predictive analysis; Adaptive learning analysis; and the analysis Dashboard. I drew and showed the use case and sequence diagrams of SEE-PAD to help design digital textbook functions.

The purpose of this study was to explore what a science lesson using a digital textbook looked like and what kinds of implications could be drawn from the lesson. The study qualitatively described a 4th grade science lesson in the unit of Earth and Moon, analyzed the structure of the lesson, and critically interpreted the meaning of it. It was revealed that the introduction of a digital science textbook did not bring about changes in the already patternized structure of elementary science instruction as well as in the manner of classroom interaction. The result was followed by discussion concerning the ways the use of a digital textbook could change elementary science instruction and enable new types of classroom interaction. It was suggested that negotiations should be reached about the nature of digital science textbooks and their developments and that the teacher's own pedagogical roles in the science classroom should be improved.

The purpose of this study was to identify the factors that determined the adoption of digital textbook among elementary and middle school teachers, and to propose and validate a revised Technology Acceptance Model. The study was grounded in the innovation diffusion theory and the attribute factors proposed in the theory were used in the model. More specifically, observability, compatibility, and subjective norms were proposed as external factors and usefulness, easy of use, intention to use were proposed as internal factors in the proposed model. It was found that (a) observability, compatibility, and subjective norms were the main external factors that influenced the teachers' intention to use digital textbook and (b) the revised TAM was validated.
