本稿では，2020年9月から10月にかけて3回にわたって実施された小学生向けプログラミングの遠隔授業について，プロジェクトの概要と成果を述べる。とくに，このプロジェクトを始めるに至った経緯，小学生向けのプログラミング教育の特徴と今回の授業内容，遠隔授業を実現するための技術的環境を中心に計画と実施後の反省点を述べる。授業は久留米大学御井キャンパスから沖縄県名護市立屋部小学校に向けて実施されたもので，授業内容は久留米大学の学生サークルteam.csvの学生が企画し，CoderDojo名護の運営者と屋部小学校教諭の協力により実施された。これらの内容を述べるとともに授業中の写真と教材を報告資料として提示する。

We investigate the diffusion and the drift motion of λ DNA molecules near solid-state nanopores prior to their translocation through the nanopores using fluorescence microscopy. The radial dependence of the electric field near a nanopore generated by an applied voltage in ionic solution can be estimated quantitatively in 3D by analyzing the motion of negatively charged DNA molecules. We find that the electric field is approximately spherically symmetric around the nanopore under the conditions investigated. In addition, DNA clogging at the nanopore was directly observed. Surprisingly, the probability of the clogging event increases with increasing external bias voltage. We also find that DNA molecules clogging the nanopore reduce the electric field amplitude at the nanopore membrane surface. To better understand these experimental results, analytical method with Ohm's law and computer simulation with Poisson and Nernst-Planck (PNP) equations are used to calculate the electric field near the nanopore. These results are of great interest in both experimental and theoretical considerations of the motion of DNA molecules near voltage-biased nanopores. These findings will also contribute to the development of solid-state nanopore-based DNA sensing devices.
