105 分授業開始 & 4/10-4/19 の輪読
2024/04/21 15:27
4/11 から今年度の授業が始まりました．茨城大学は今年度から授業時間が 105 分（従来は 90 分）になりました．90 分授業の場合は 2 単位の科目で 15 回の授業と期末試験で 16 週が必要となったのですが，105 分授業ならばこれが，13 回の授業+期末試験で 14 週で済むことになります．これによって，夏季・春季休業期間と補講期間を確保するというのがこの変更の狙いになっています．実は授業をする立場では（少なくとも私の場合）90 分でも 105 分でもそれほどの違いは感じません．一生懸命しゃべっていると案外時間の流れは速く感じるものです．しかし，聴く方の立場では 90 分でも結構長いと感じる学生の皆さんは多いと思うので，105 分でも受講生を飽きさせない授業にするというのは結構難しいと思います．

仕事始め，105 分授業，今週の輪読
2023/01/07 11:49
1/4 から業務開始，1/6 から授業開始となりました．授業開始の後にすぐに三連休となったので，遠方に帰省している学生にとってはちょっと厳しい日程になりました．近年は授業回数の確保が厳格化されているためにどうしても厳しいスケジュールになってしまう傾向があります．
そういう問題を解決するという意味もあって，2024 年 4 月から茨城大学では従来の 90 分授業を 105 分授業に変更することが決定されています（令和６年度からの授業時間の変更について）．これにより今までの 15 回+期末試験が 13 回+期末試験に変更になるため，授業のスケジュールに余裕を持たせられるようになることが期待されています．しかし，その代償として一コマの授業がかなり長時間になってしまうので，教える立場としては授業をより一層工夫しないと 90 分でも飽きられてしまいがちなのに，さらに学生に飽きられてしまいそうです．また，5 講時終了は 18:45 とかなり遅い時刻になってしまいます．
今週の輪読は 1/5 から始めて下記の論文を取り上げました．

茨城大学は 12/26 が冬休み前の最後の授業日で，12/27 からは教職員も原則的に計画年休を取得することになっているため，仕事納めにもなりました．まだまだコロナ問題が続いているため，今年も忘年会などはなく，静かに年末を迎えています．新年は 1/4 が仕事始めで，授業開始は 1/6 です．

茨城大学では 8/2（火）〜8/8（月）が期末試験期間になっています．ちょうど新型コロナウイルス感染症の第 7 波の真っ最中なので，感染者や濃厚接触者になり試験が受けられなくなってしまう学生も多発しているのではないかと思われます．ニュースによると東大教養学部ではコロナ感染者に対する救済策がなく大騒ぎになっているようですが，茨大では基本的に追試験対象者になるので，コロナに罹ったから留年というような事態は起こらないはずです．
長谷川が担当している二年生向けの科目「一般化学 II」では今年度から通常の期末試験期間の一週間前に期末試験を実施し，期末試験の時間帯に期末試験の振り返りの授業を行うやり方にしました．大学では期末試験を受けたら後は野となれ山となれという感じの授業がほとんどですが，本来はできなかった問題を復習することが重要だと思います．

7/23（土）には茨城大学オープンキャンパスが開催されました．阿見キャンパス会場にも多くの高校生や保護者の皆さんが来訪されました．過去 2 年間は新型コロナウイルス感染症の影響で，来場型のオープンキャンパスを開催することができませんでしたが，今年度は感染拡大の中ではありましたが，なんとか開催することができました．長谷川は農学部広報委員長という立場でしたので，学部全体に関わる業務を担当していましたが，研究室公開は戸嶋先生と研究室の学生さんに担当してもらって，30 名程度の訪問があったようです．
先週の研究室セミナーでは化学生態学研究室 4 年生の学生が下記の論文を紹介しました．

世間はゴールデンウィークで九連休という人も多いようですが，茨城大学の授業は完全に暦通りだったので，今週の月曜日と金曜日は通常通りに授業がありました．最近の大学では授業時間の確保が厳密に管理されているので，貴重な平日に授業を入れないという選択肢はないのです．それどころか，一部の大学では火水木の三連休も通常通り授業を行なっているところがあったようです．
今週の輪読も金曜日に一回だけしか行えませんでしたが，下記の論文を取り上げました．

長谷川は今年度は農学部広報委員長という役割なのですが，その仕事の一つとして 4/27 に埼玉県立川口北高等学校での進学説明会に出席してきました．新型コロナウイルスのパンデミック発生でめっきり出張の機会が減っていて，県外へ出張するのはおそらく 2020 年 3 月以来二年ぶりだったと思います．また，この日は 1 講時にオンラインの授業があり，埼玉から戻ってきてもまた社会人学生向けの授業があるというハードスケジュールでした．
今週の輪読は授業と上記の出張と授業の関係で木曜日に一回だけしか行えませんでしたが，下記の論文を取り上げました．

茨城大学は 1/4 から仕事始めで，授業は 1/6 開始でした．しかし，1/6 は昼過ぎから雪が降り始めて翌日の路面凍結が予想されれたため，農学部では 1/7 の対面授業は休講になりました．私の担当している植物代謝機能学は 1/7 の 1 講時に実施予定でしたが，休講になってしまいました．確かに 1/7 の朝は徒歩でも所々スリップしそうになりそうな所がある状態だったので，休講措置は妥当だったと思います．

後学期開始，ワクチン接種，今週の輪読
2021/10/01 14:10
茨城大学では 9/29 から後学期の授業が開始しました．9/30 で緊急事態宣言は解除になりましたが，10/12 までは原則的に遠隔授業にすることが前もって決まっていましたので，現在のところほとんど全ての授業はオンラインで実施されていて，学生さん達が本格的にキャンパスに戻ってくるのは 10/13 以降になりそうです．
学生対象の新型コロナウイルスワクチンの職域接種は今週で 2 回目が完了しました．モデルナ製ワクチンは 2 回目の副反応がなかなか厳しいので，研究室の学生たちも接種翌日はダウンしていたようです．私（長谷川）は茨城県の大規模接種会場でモデルナ製ワクチンの接種を 7, 8 月に受けましたが，やはり 2 回目接種の翌日は 38.6 ℃ まで体温が上がってかなりきつかったです．まあ寝てれば熱は下がるので，コロナにかかることを思えば，どうということはないのですが．
今週の輪読では下記の論文を取り上げました．

茨城大学は 8/10 が期末試験の最終日で前期と第 2 クォーターが終了しました．長谷川が担当している一般化学 II も 8/6 の期末試験を対面で実施して終了です．7 月後半から新型コロナウイルス感染症のいわゆる第 5 波が来て授業が通常通り続けられるか心配していましたが，何とか逃げ切りました．夏休み中も集中講義（今年度は私は担当していません）はありますが，おそらくほとんど遠隔授業になりそうです．後学期が始まる 9 月末ごろまでにはワクチン接種も進んで，感染状況が落ち着くことを期待しています．

年間計画発表会 & 今週の輪読
2021/05/14 13:45
今週の木曜日には修士 1 年生と学部 4 年生の修士論文と卒業論文研究の年間計画発表会が生物制御化学研究室と化学生態学研究室合同で開催されました．修士 2 年は先週中間発表会を開催済みです．今年度の M1 は 2 名，4 年生は 6 名です．皆さん意欲的な計画で，計画通りに研究が進めば修論・卒論だけでなく原著論文もバンバン出そうなのですが，そこは計画通りにいかないのが研究の難しくも面白いところです．
今週の輪読では下記の論文を取り上げました．
