A Report on Overseas Teaching Practicum by Graduate Students in Elementary/Secondary Schools in the United States（Ⅺ）

This paper reports on the 11th overseas teaching practicum in the U.S. 12 students joined this year’s program and they observed and conducted lessons in English in three local public schools in North Carolina after careful and repeated preparation sessions in Japan. Many of them did lessons on crosscultural understandings and a few taught subject contents. Through the trail to convey messages in English, their foreign language, students learned the role of verbal and nonverbal language and the more universal way to explain topics to children who are unfamiliar with what re taught. And they also learned and noticed the cultural differences and similalities between the two countries. It seemed that students realized that the two countries share many things in common such as what chidren are like, teachers’ attitude toward children and challenges they are facing, and people’s kindness. These learning was no substitute experience for the participants and it is hoped that their experience will be passed to the next generation when they become teachers

Venus's induced magnetosphere during active solar wind conditions at BepiColombo's Venus 1 flyby

International audienceOut of the two Venus flybys that BepiColombo uses as a gravity assist manoeuvre to finally arrive at Mercury, the first took place on 15 October 2020. After passing the bow shock, the spacecraft travelled along the induced magnetotail, crossing it mainly in the YVSO direction. In this paper, the BepiColombo Mercury Planetary Orbiter Magnetometer (MPO-MAG) data are discussed, with support from three other plasma instruments: the Planetary Ion Camera (SERENA-PICAM) of the SERENA suite, the Mercury Electron Analyser (MEA), and the BepiColombo Radiation Monitor (BERM). Behind the bow shock crossing, the magnetic field showed a draping pattern consistent with field lines connected to the interplanetary magnetic field wrapping around the planet. This flyby showed a highly active magnetotail, with e.g. strong flapping motions at a period of ∼7 min. This activity was driven by solar wind conditions. Just before this flyby, Venus's induced magnetosphere was impacted by a stealth coronal mass ejection, of which the trailing side was still interacting with it during the flyby. This flyby is a unique opportunity to study the full length and structure of the induced magnetotail of Venus, indicating that the tail was most likely still present at about 48 Venus radii
