However, in Japan, remote classes cannot be unconditionally substituted for in-person classes. Thus, there is a need to evaluate the educational effects of remote classes, taking into account the academic field and other aspects of the class, such as whether it is a lecture class or a laboratory exercise class. In this study, I investigate the educational effects of introducing remote learning by comparing class questionnaires and lab report and test scores from 2020 and 2021 with those from 2019 in the College of Science and Technology at Nihon University, where I am an associate professor. The classes surveyed were Control Engineering, which is a lecture class, and Electrical and Electronic Engineering Experiments, which is a laboratory exercise class. The results of the class questionnaire analysis showed that on-demand classes were poorly evaluated by students, whereas hybrid remote classes were highly evaluated. The results of the lab report and test score analysis revealed a widening gap in the level of understanding among students in remote classes compared with in-person classes.","PeriodicalId":23081,"journal":{"name":"The transactions of the Institute of Electrical Engineers of Japan.A","volume":"69 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135161376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the content of the circuit design workshop was discussed and it was determined that a connection-focused design would be appropriate. Second, we examined the issue of existing teaching materials. Many of the existing kit materials were not suitable for learning circuit design as it was already completed. In addition, many of them required soldering work, which was too difficult for elementary school students. Hands-on materials that allow students to construct circuits through trial and error were suitable for learning circuit design. Therefore, we developed design and fabrication support materials using a 3D printer and conductive tape. Next, we provided workshop opportunities using developed material, with the theme of “making light-up cards,” wherein elementary school students worked on designing the layout of the components and fabrication. Consequently, students' conceptual understanding of the connection was improved. All students were able to complete the circuit, with high self-evaluations of satisfaction and understanding suggesting that the activity was engineering-oriented.","PeriodicalId":23081,"journal":{"name":"The transactions of the Institute of Electrical Engineers of Japan.A","volume":"19 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135161105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the LIPSS generated upon the irradiation of various semiconductor materials with a train of 11.4 µm femtosecond laser pulses were examined. The laser source was a Mid-infrared free-electron laser (MIR-FEL). Eight semiconductor substrates (i.e., Si, Ge, ZnO, SiC-4H, GaP, GaN, CdTe, and SiO2) were used as the targets. On Si, Ge, SiC-4H, and GaN, the LIPSS were oriented parallel to the MIR-FEL polarization with interspaces of 1/8 to 1/4 of the MIR-FEL wavelength λFEL. These interspaces tended to match the wavelength of the second harmonic of the MIR-FEL light propagating in the substrates. The obtained F// were relatively correlated with the bandgap energies of materials, as were those for near-infrared femtosecond lasers. Another type of LIPSS oriented perpendicular to the MIR-FEL polarization with interspaces of λFEL to λFEL/9 was also observed in the same spot on SiC-4H or GaN at higher fluences than only //-LIPSS was formed.","PeriodicalId":23081,"journal":{"name":"The transactions of the Institute of Electrical Engineers of Japan.A","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135372330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
