高校数学のインチキ総集編!

専門数学の観点から見た,高校数学の奇妙さを一冊にまとめました。

・高校の数学教師がよく使うおかしな説明
・教育的配慮から生まれた,高校数学の不思議なローカルルール

高校生も,高校の先生も,塾や予備校の先生も,大学の先生も,数学に携わるすべての人に読んでいただきたい一冊です。

[まえがき]
 私は,教師として中学生や高校生に数学を教える立場にある。以前は,学生として専門の幾何学を学んでいた。代数学も解析学も,確率論や統計学なども,基礎的なことは一通り学んだ。学べば学ぶほど,数学は途方もなく広大な宇宙であることを実感する。そんな宇宙の片鱗を学び,満を持して私は教員となった。専門数学とは少々雰囲気が異なる,数学教育の世界である。

 教育現場で数学を語るとき,何とも言えない心地悪さを感じることがある。誤解を承知で述べるならば,世界が狭い。いや,数学教育の可能性こそ無限の宇宙であることに違いないが,数学という宇宙を見た後では,高校数学の世界はあまりにも狭い。そして,どうやらこの世界の数学には,数多くのローカルルールが存在するらしい。もちろん,私自身にも高校生時代があったのだから,高校数学のルールくらい当然存じ上げていたことではあるが,いざ専門数学の宇宙から高校数学の世界を俯瞰すると,もやもやするような違和感が至る所に存在している。
