  • The purpose of this study was to develop an inquiry-based professional development program for in-service secondary science teachers and to investigate it's application. The inquiry-based professional development program was reconstructed based on SSCS problem-solving model, which is composed of 4 stages of search, solve, create, and share. The 28 science teachers' understanding of the SSCS program were investigated as implementing the program. As a result of this study, 8 SSCS modules have developed as the science teachers have searched, solved, created, and shared various situated problems. The science teachers found themselves to have positive perception of SSCS program. The SSCS program was effective in changing the learners' teaching/learning attitude and to develop individual scientific thinking. To make the SSCS problem solving successful and more effective, both science teachers' professionalism and pedagogical knowledge for selecting topic as the levels of learner should be considered.

  • Integrative STEM education is an engineering design-based learning approach that purposefully integrates the content and process of STEM disciplines and can extend its concept to integration with other school subjects. This study was part of fundamental research to develop an integrative STEM education program based on the science inquiry process. The specific objectives of this study were to review relevant literature related to STEM education, analyze the key elements and value of STEM education, develop an integrative STEM education model based on the science inquiry process, and suggest an exemplary program. This study conducted a systematic literature review to confirm key elements for integrative STEM education and finally constructed the integrative STEM education model through analyzing key inquiry processes extracted from prior studies. This model turned out to be valid because the average CVR value obtained from expert group was 0.78. The integrative STEM education model based on the science inquiry process consisted of two perspectives of the content and inquiry process. The content can contain science, technology, engineering, and liberal arts/artistic topics that students can learn in a real world context/problem. Also, the inquiry process is a problem-solving process that contains design and construction and is based on the science inquiry. It could integrate the technological/engineering problem solving process and/or mathematical problem solving process. Students can improve their interest in STEM subjects by analyzing real world problems, designing possible solutions, and implementing the best design as well as acquire knowledge, inquiry methods, and skills systematically. In addition, the developed programs could be utilized in schools to enhance students' understanding of STEM disciplines and interest in mathematics and science. The programs could be used as a basis for fostering convergence literacy and cultivating integrated and design-based problem-solving ability.

  • This study aims to find out the feasibility and effectiveness of mathematical games as a way to provide primary pre-service teachers with doing mathematics. The game had induced the active participation of elementary pre-service teachers. Through transforming the game, the teachers have been able to experience of mathematical problem posing and generating mathematical representation. Based on this, we discuss the role of mathematical games as a method of pre-service teacher education.

  • It is an orthodox in epistemology that only those things that affect the truth conduciveness of a belief are relevant to the epistemic rationality of the belief. I criticize this orthodox. In this paper, 1 claim that the epistemic worth of a subject affects the epistemic rationality of inquiries and resulting beliefs. More specifically, I argue that it is epistemically irrational to conduct an inquiry when it is about something unworthy of knowing, and that the epistemic irrationality of an inquiry in this sense makes the resulting beliefs epistemically irrational. After presenting my argument, I defend it from various possible criticisms. Then I explicate the implications of my argument that opposes the core assumptions of contemporary epistemology.
