サケの授業

 小学校の先生をなさっている”ひろすけ”さんのブログで、「サケがおおきくなるまで」というエッセイを使った授業について書かれています。

微睡み日記:さけが大きくなるまで<一時間目>

 この「さけが大きくなるまで」は小学校2年生の国語の副読本?に指定されているのか、こちらとか、こちらなどで授業についての報告がされています。ぐぐるとかなりのヒットがありますので、普及している副読本かと思われます。

 で、記事を拝見して興味を持ったのは学習の目標に「サケの大きさを理解させる」、という部分と「生きたサケのイメージを持たせる」という部分です。私もサケ漁をしている集落の小学生に話をする、という機会があり、その際漁法とか文化よりもサケという魚を理解させることに重点を置きました。その際、親族にさけ漁をしている子供が何人かいるにも関わらず、サケの全身をみたことがある子供が少ない(半分程度)ということに驚き、また、大きさを説明する際、だいたい3kgから4kgですから、ペットボトル2本分とか説明すると、「すげー」という反応が返ってきたことが印象に残っています。人文系でも自然系でも生物を扱う場合、まず対象に対する具体的なイメージを持たせることがとても重要だと知った時でした。

 ちなみに、子どもたちに説明した際、一番印象に残ったらしい話は、産卵場でオスがメスを奪い合ってけんかをし、人間がサケを採る際は、負けたオスをねらう、という話でした。実際、産卵場でのサケ漁が場所の下流側に網などを仕掛け、負けて流されたオスを採ることが多いのですが、その部分の説明です。これを男の子、女の子に置き換えて説明をしたのがよかったようですが、子供に説明するときはどのように比喩を使うのかが難しいですね。

教えて下さい。さけの赤ちゃんは、どうやって50cmも下の小石の中から出てこれたのですか?
赤ちゃんのおなかについている、ぐみのみのようなものは何ですか?たまごのから?えいよう?
赤ちゃんは、なにを食べるのですか?

投稿者: ますこ しおん (Dec 10, 2004 7:49:57 PM)

 ごめんなさい。ちゃんと調べればよいのですが、仕事がいそがしく余裕がないものでひとまず記憶から簡単にお答えさせて頂きます。
 まず、小石に生む理由が稚魚が生きていけるスペースがあるためで、大きくなると石のすきまをぬって出てきます。
 それからおなかのグミは”さいのう”といい、小石の中で生活していく間のえいようになっています。
 このさいのうがだんだん小さくなり、最後なくなると小石から出て川の中をおよぎまわるようになります。
 川のなかのエサはわかりません。調べたらまた返事をさせていただきます。

ありがとうございます。2年生の娘が、国語の授業で『さけが大きくなるまで』を習っていて、いろいろと質問してきます。図書館で調べたりもしたのですが、知りたい事が載ってなくて…。娘は返事が来て、とても喜んでおりました。忙しくて、お礼が遅れてしまって申し訳ありません。また何かあったら、書き込みさせていただきます。

投稿者: しおん (Dec 26, 2004 11:57:27 PM)

あ、やはりお子さんでしたか。この程度でよろしかったでしょうか。大した返事もできずもうしわけありませんでした。
 生物系は専門外なのでどこまで適切なお答えができるかわかりませんが、可能な限りお答えさせていただきます。
 今後ともよろしくお願いします。
