“…There have been discussions on effective teaching of combining ICT with academic writing or math teaching not only in primary and secondary education but also in higher education [16]- [18]. There have been increased cases using ICT in higher education in the area of academic business from registration to graduation [19].…”

ICT use in education is a key instrument to enhance educational quality and change the educational paradigm. For example, Korea has been using computers and Internet into primary and secondary schools since the 1980s. There have been many educational policies for ICT use in education. Not only developed countries but also developing countries make a lot of effort to enhance the quality of education by using ICT in education. First of all, ICT competence of teachers is very important in order that ICT can be an effective tool in education. The level of teachers' ICT competence decides the level of using ICT in education. However, it is not easy for many teachers to take training for enhancing the level of ICT competence in a short time. This study suggests an elearning system for strengthening the ICT competence of teachers by using an example of an educational environment in Nicaragua. Since this e-learning system can be operated by using cloud computing technology, it will provide implications for education projects with ICT use in primary and secondary schools in developing countries.

Schema matching plays a vital role in the information integration process from heterogeneous databases. Generally, the process of schema matching is to receive input, which are two databases (one as the source and another as a target), to match similarity attributes, and generate output in the form of mapping the similarity of the attribute pairs that are declared suitable. Furthermore, the user will assess these attribute pairs to determine whether the results obtained are correct or still need to be revised. Our previous study developed a model and software prototype of hybrid schema matching using a combination of constraint-based method and instancebased method. In this study, the model improved by adding new features. This paper discusses the increasing effectiveness of adding the features to customize the weight of matching criteria and string sizes matching. The hybrid model's best effectiveness is obtained when the weight of instance is 0.286, the type is 0.238, width is 0.190, nullable is 0.143, unique is 0.095, and the domain is 0.048. The matching process using a bigger string size increases the model effectiveness with the highest precision of 97.66 when the string size interval is between (length-100) and (length+100). The best combination of weight and string size variation obtains 97.66% precision, a 99.90% recall, and an f-measure of 98.74%.

Schema matching is a crucial issue in applications that involve multiple databases from heterogeneous sources. Schema matching evolves from a manual process to a semiautomated process to effectively guide users in finding commonalities between schema elements. New models are generally developed using a combination of methods to improve the effectiveness of schema matching results. Our previous research has developed a prototype of hybrid schema matching utilizing a combination of constraints-based method and an instance-based method. The innovation of this paper presents a mathematical formulation of a hybrid schema matching model so it can be run for different cases and becomes the basis of development to improve the effectiveness of output and or efficiency during schema matching process. The developed mathematical model serves to perform the main task in the schema matching process that matches the similarity between attributes, calculates the similarity value of the attribute pair, and specifies the matching attribute pair. Based on the test results, a hybrid schema matching model is more effective than the constraints-based method or instance-based method run individually. The more matching criteria used in the schema matching provide better mapping results. The model developed is limited to schema matching processes in the relational model database.
