STEM education is a crucial learning area to understand important concepts and gain 21st-century skills in different disciplines, explore scientific knowledge, and solve problems in daily life. However, research in STEM education is scarce on extended reality technologies. This research examined the effects of extended reality integrated STEM on students’ learning response and performance. A quasi-experimental research design was used to find answers to the research questions. The same lecture taught the experimental and control groups but preceded STEM experimental activities at a different time and with distinct instructional strategies and teaching aids. The participants were students in two classes at a university in Taiwan. The research results showed that students in the experimental group applying extended reality-integrated STEM had better learning responses than students in the control group using teaching materials. The results also showed that students in the experimental group learning with an extended reality system could apply the STEM curriculum knowledge acquired in classes and reflect the learning outcomes on the test assessment for better learning performance than students in the control group. In addition, the results revealed that good learning responses could enhance students’ higher learning performance. In light of the results, educational implications are made.

MCMD problems with fuzzy preference information on alternatives are essential problems of the importance of weighting and ranking. In this study, the AHP method is reviewed, and then Fuzzy PreRa and incomplete linguistic preference relations methods are elucidated. This study applied above three MCDM methods to a software selection problem proposed by Lai et al. [Software selection: a case study of the application of the analytical hierarchical process to the selection of a multimedia authoring system, Information and Management, Vol. 36, 1999, pp. 221-232.]. The outcome obtained by Fuzzy PreRa and incomplete linguistic preference relations methods almost coincides with that produced by the AHP method, also with the least judgments. The result shows that the approach developed is simple and comprehensible in concept, efficient in computation, and robust in modeling human evaluation processes which make it of general use for solving practical qualitative multi-criteria problems.

This study provides a method to solve the incomplete linguistic preference relations under multi-criteria decision making. The method uses simple calculation and can speed up the process of comparison and selection of alternative. Decision-making experts obtain the matrix by choosing a finite and fixed set of alternatives and set a pairwise comparison based on their different preferences and knowledge. The method considers only n-1 judgments, whereas the traditional analytic hierarchy approach takes n(n -1)/2 judgments in a preference matrix with n elements. By using the method described above, this study evaluates the ERP system suppliers.

Middle managers act as a role of changing agent, focus on strategy implementation, and bridge the senior management level and the front lines. The purposes of this study are to assess the management competencies for middle managers; and to evaluate, from the point of view of supervisors, the candidates for middle managers by Fuzzy Analytic Hierarchy Process (FAHP). This study found that after data collected from field expert questionnaire survey and analyzed by FAHP the result provides ranking for the management competency assessment for middle managers.

The fast development of the network has caused a great impact on teachers who engage in the forefront educational works. For conforming to the demand of the internet era, it is an inevitable trend to train the teachers themselves to acquire the basic information literacy. In order to provide references for relevant units to initiate teachers' professional training programs, this study, through questionnaire, explored current situation about the information literacy of elementary teachers, and analyzed the relationship between the information literacy and the personal background. Based on the "The Indexes of Information Literacy of Teachers in Elementary and Secondary Schools" promulgated by the Ministry of Education, the questionnaire was developed and sent to 120 elementary teachers in Kaohsiung Taiwan. This research found that "professional literacy of information curriculum", "operational literacy of computer software", "basic literacy of the application to web-based instruction in disciplines", and "whole information literacy" are related to sex, ages, total service years, and weekly hours of computer usage.
