Abstract:
The purposes of this research are 1) to study the need assessment and confirmatory factors of the mobile application development. 2) to develop the mobile application 3) to study the use of mobile application and 4) to present the mobile application. The sample for developing the application were from 18 experts, 10 teachers and 980 junior high school students from public and private schools in Thailand. The research instruments were interviews, questionnaires and an application quality assessment. The experimental sample group were 30 junior high school students. The instruments for the experiment were mobile application system assessment form, financial management competency scale, learning behavior observation form, satisfaction assessment form with the system. The data were analyzed using content analysis, percentage, mean, standard deviation, need assessments, confirmatory factor analysis by using LISR program and T-test. The research found that the mobile application system developnent is comprised of 5 components 1) scenario-based learning content 2) promoting mobile learning strategies 3) social communication and learning communities, 4) activities and instructional media, and 5) learning resources. There are 6 processes; 1) introduction and providing knowledge 2) learning activities using scenario-based learning 3) studying the problems and solving the problems. 4) Scaffolding by experts via mobile by soft scaffolding and hard scaffolding 5) sharing in social learning networks 6) discussion and conclusion on social media and 7) assessment and evaluation. The experimental results of the mobile application system found that the average score of the financial management competency after the study of the sample was higher than the average of the financial management competency before studying with the statistical significance at a level of .05. Moreover, after analyzing the level of empowerment by experts to enhance financial management capabilities and learners who have a high number of frequency enhancing learning potential, resulting in a high financial management competency score. On the other hand, those with a low number of frequencies to enhance their learning potential will result in lower financial management performance scores.
