In this study, the standard model of next-generation software(SW) education was developed to expand SW education for fostering future talents and to prepare a consistent SW education application system for elementary, middle and high schools in the next revised curriculum. To this end, based on the study of the standard model for elementary and secondary SW education conducted in 2017~2018 academics, basic research and analysis on domestic and foreign SW education, public forums of related organizations and experts, global SW education workshops, and public hearings are held. Through this process, a consistent application system for SW education in elementary, middle, and high schools was established, and the next generation SW education standard curriculum model that can be connected to higher education and industry was developed.

The purpose of this study is to explore characteristics of on-line teaching materials on websites of natural history museums, particularly with regard to educational perspectives and the nature of science. The target resources were selected from the websites of the Natural History Museum in London, the Australian Museum in Sydney, the Field Museum of Natural History in Chicago, and the Smithsonian Museum in Washington D.C.. A total of twelve on-line resources from these museums used in this study were selected as representative informal science teaching materials. For the investigation, this study developed a checklist with a total of nine items that were grounded on mostly reviewing previous literature and articles focusing on educational perspectives of natural history museums and science centers. Exciting and positive results were found in all four museums. The analyses, however, indicated weaknesses as well as strengths in on-line resources regarding their usages as informal science teaching venues.

Benzosilacyclobutenes were prepared from the reactions of 1,1-dichlorobenzosilacyclobutene with Grignard reagents or t-butyllithium. In the thermal reactions with alcohols, benzosilacyclobutenes underwent both benzyl-silicon and aryl-silicon bond rupture to yield (dialkyl)alkoxy-o-tolylsilanes and (dialkyl)alkoxybenzylsilanes, respectively. The photochemical reactions, however, produced only the former products via o-silaquinone methides.
