Linear Algebra are arguably the most popular math subjects in colleges. We believe that students' learning and understanding of linear algebra can be improved substantially if we incorporate the latest advanced information technologies in our teaching. We found that the open source mathematics program 'Sage' (http://sagemath.org) can be a good candidate to achieve our goal of improving students' interest and learning of linear algebra. In particular, we developed a simple mobile content which is available for Sage commands on common cell phones in 2009. In this paper, we introduce the mobile Sage which contains many Sage functions on a smart-phone and the mobile linear algebra content model(lecture notes, and video lectures, problem solving, and CAS tools) and it will be useful to students for self-directed learning in college mathematics education.

Concerning elementary school science subject electric circuit units, which are regarded as difficult by teachers and students, this study aims to use the knowledge state analysis method along with interviews to analyze the knowledge state and hierarchy of inquiry abilities. Before and after applying the electric circuit inquiry abilities module, the question items aimed at assessing the basic inquiry abilities and integrative inquiry abilities for electric circuits were presented to students, and their knowledge state was analyzed along with interviews. Through analysis of the knowledge structure and hierarchy of inquiry abilities about electric circuits, the way of thinking of teachers who taught inquiry abilities, and the way of thinking of students were found to be visually different from each other, and this is an important factor that should not be neglected in the process of teaching and learning about inquiry abilities and should be considered. In addition, the presentation of the knowledge state of and hierarchical relations between inquiry abilities factors can offer implications for guidance on students' learning about inquiry abilities.

In recent years, various educational institutions have used online certificate services to verify academic achievement related to graduation and grades. However, the certificate of the existing system has limitations in verifying and tracking whether it is true or not and detailed academic background. In this regard, cases of forgery/falsification of online/offline certificates continue to occur. This study proposes a blockchain-based verification method that is safe from forgery and alteration, focusing on university institutions. Necessary information such as detailed class categories for each department, attendance, and detailed grades was collected/analyzed to create a linkage relationship through blockchain. In addition, the system/network environment required for blockchain sharing was considered, and it was implemented as an extension module in the form of an independent web application. As a result of the block chain verification, it was proved that the safe trust verification of educational information and the relationship between detailed information can be traced. This study aims to contribute to the improvement of academic credential verification services and information security for Korean educational institutions in the future.
