  • In the field of artificial intelligence education, discussions on the direction of artificial intelligence education are actively underway, and it is necessary to establish a foundation for future information education. It is necessary to design a creative convergence teaching-learning and evaluation method. Although AI experience coding education has been applied, the evaluation stage is insufficient. In this paper, we propose an evaluation system that can verify the validity of the proposed education model to find a way to supplement the existing learning module. The core components of this proposed system are Assessment-Factor, Self-Diagnosis, Item Bank, and Evaluation Result modules, which are designed to enable system access according to the roles of administrator, instructors and learners. This system enables individualized learning through online and offline connection.

  • Preservation of fresh algae plays an important role in algae seed subculture and aquaculture. The determination and examination of the changes of cell viability, composition, and bacterial species during storage would help to take suitable preservation methods to prolong the preservation time of fresh algae. Nostoc flagelliforme is a kind of edible cyanobacterium with important herbal and dietary values. This article investigated the changes of bacterial species and biochemical characteristics of fresh N. flagelliforme concentrate during natural storage. It was found that the viability of cells decreased along with the storage time. Fourteen bacteria strains in the algae concentrate were identified by PCR-DGGE and were grouped into four phyla, including Cyanobacteria, Firmicutes, Proteobacteria, and Bacteroidetes. Among them, Enterococcus viikkiensis may be a concern in the preservation. Eleven volatile organic compounds were identified from N. flagelliforme cells, in which geosmin could be treated as an indicator of the freshness of N. flagelliforme. The occurrence of indole compound may be an indicator of the degradation of cells.

  • Building a competency of pre-service school teachers is one of the critical factors to decide right direction of k-12 computer & information education. In this context, we can realize of the importance of computer & information curriculum for pre-service school teachers. The purpose of this study is to explore the case of the CEL(Computer Educator License) program in Indiana University and to find the developmental direction of technology education for pre-service school teachers. To achieve the purpose of study, the methods and procedures involved the following steps: The literature reviews of technology education were performed. The analysis framework based on case study method was designed for collecting data. Data were composed of related documents, web resources, and interview resources. And collected data were analyzed. The finding and recommendation of this study were the importance of following factors: (a) technology integration in the curriculum for pre-service school teachers, (b) differentiated management with skill-based technology education, (c) leadership for using and diffusing technology in the school, and (d) connected curriculum with the national standard indicator.

  • The purpose of this research is to suggest the way to promote housewives' understanding of science and technology, based on the survey results of the attitude toward science and technology, the scientific attitude, and the interest in science and technology of housewives in Korea. The questionnaire was developed by researchers and administered to housewives who live in Seoul to get basic information. Housewives showed slightly positive attitudes toward science and technology, and similarly positive scientific attitudes. These scores were increased as monthly income and education level were raised. Housewives' interest of the science-technology related topics (foods, health, education, leisure, social issues, cooking, housing, everyday activity) was relatively high, and the interest of foods, health, education, and leisure was significantly correlated with the scores of housewives' attitude towards science and technology and their scientific attitudes. Housewives are shown to be curious to know these topics when they were asked by their children or do not know the terms appeared in media, or purchase home appliances and food. And they get the answers in a passive way by asking their family members or by watching TV or newspapers. They preferred TV program for enhancing their understanding of science. But such program could be proper to present science knowledge but not fulfill the role to promote scientific literacy. Specially designed programs through science centers or science museums would be suggested for their lifelong education.

  • This article explores how the use of technology along with carefully designed tasks can advance equity in the teaching of mathematics. Focusing on one of the dimensions of the EQTTech lesson analysis tool, this study examines how the use of technology can support the development of authority, identity, and agency in minoritized high school youth. A lesson on central tendency was designed and enacted in two 9th grade classrooms using GeoGebra and Padlet technologies. Student work and video recordings of the lesson were analyzed for student expressions of authority, identity and agency. These key constructs were intertwined in practice, and appear to be supported by the pairing of carefully selected tasks with technology chosen for its potential to advance equity.
