1c:Tbdd,答えを写経する勉強は、不合格者の典型例です。(自分もそれで一浪しました) 数学の問題を解く上で、絶対に押さえておくべきポイントがあります。 ・求めたい答えは何か(xの範囲、〜となる条件、グラフなど) ・与えられた条件は何か(xは-1〜5の〜、aは実数など) ・条件から答えを引きずり出せる手段は何か (解と係数の関係、判別式、次数下げなど) この答え、条件、手段の3セットが揃えば、数学の問題は解けます。 問題が解けないときは、このうちどれかがわかっていないのです。 数学の勉強法としては ・まず問題文を読む 求める答え、ゴールを確認して、それから与えられた条件を探します。 数学における情報、条件は日本語の問題文に翻訳されているので、じっくり考えないと見つからないこともあります。 ・条件と答えをどう繋げるか考える 与えられた条件、目指すべきゴールがわかったら、答えを出せる手段を考えます。 これで手段が思いつけば、実行して計算して終わりです。 わからない場合、長く考えなくていいです。答えと条件を洗い直してダメなら、潔く模範回答を見る。 わからないものはどれだけ考えてもわかりませんから。 ・解説を見て分析する ここが数学の勉強のメインです。ここ以外を多少おろそかにしてでも、ここだけはたっぷり時間をかけてください。 解説を見れば、正しい答え、条件、手段がわかります。 このうちどこで自分が詰まったのか、何を知っていれば解けたのか、ここを確認して、記録しておきましょう。 この分析を繰り返せば、整数やベクトルなどの各分野における自分の苦手なポイント、知識が蓄積されます。 そしてこの分析を半年も続ければ、高校数学の出題パターンが見えてきます。 出題範囲も問われる技能も決まっている以上、どれだけ問題が多くとも問われる内容は一定のパターンにはまってくるのです。 ・復習でもう一度解き直す これは2週目からの話ですが、正直チャート例題を高2中に一周できるか怪しいと思います。無理に2週目を目指すより、まずは納得できるまで一問を分析すること。高2中に一周できなくとも構いません。 問題のレベルは例題だけでいいです。チャートはとにかく量が多いので、例題だけでも十分すぎるくらいです。 英語に関しては単語をやりつつ、文法、語法を周回するくらいでいいと思います。高2でそこまでできるだけでもすごい。 英語は数学以上に復習と周回が大事ですから、覚えたところは飛ばしつつバンバン周回しましょう。1d:Td43,まずは数学の入試で求められる力が何かを考え入試で求められる力が何かを考えてみましょう。数学の入試で求められる力は主に3個あります。 1.『計算力』 これはいうまでもないでしょう。どれだけ正しいことを言っていても、またどれほど美しい解法を選択していたとしても途中で計算を間違えていれば、ほぼ0点になってしまいます。 2.『基本問題を覚えているかどうか』 ここでいう基本問題は青チャートのコンパス4個以下のもの、あるいは黄チャートに載っているすべての問題を指します。このレベルの問題で解けない問題が一つでもあれば難関大、ひいては東北大学の入試問題には太刀打ちできないと思います。 3.『基本問題を組み合わせられるか』 これがいわゆる「発想」と呼ばれる段階です。（今回は基礎に関する質問なので詳しくは述べません） さて以上の3個のうち、基礎と言えるのは1と2の二つを合わせた力です。つまり、基礎が固まっている状態というのは、 「黄色チャートの問題すべてで瞬間的に解法が思いつき、計算ミスを一切すること計算ミスを一切することなくミスを一切することなく正解一切することなく正解に辿りすることなく正解に辿り着けること」 だということができます。 続いて効率的な基礎の固め方についてです。上に述べたことを踏まえれば、基礎を固める＝チャート式を完璧にすることです。なので僕がやっていた方法を紹介僕がやっていた方法を紹介します。 (Step1)とりあえず解いてみる。この時5分くらいは悩んでもいいと思います。答えが出なくてもOK です。 (Step2)間違えたら→✖️、 　　　あってたけど次解ける自信がない→△ 　　　あってて次も解けそう→◯ 　　　のように印をつけて分類。 (Step3)上のStepを繰り返してとりあえず一周する（できるだけ短い時間で一周したい） (Step4)×と△の問題のみ二周目をやる (Step5~)上のことを繰り返す これだけです。めっちゃ大変ですが、チャートは避けて通れません。上の方法を参考にしながらやって上の方法を参考にしながらやってみてください！ラストはこれが本当にできてるのかのチェックの仕方です。それはズバリ教科書傍用問題集を解くということです。解説がないからダメと言われていますが、基礎の確認にはもってこいなんですよね。レベルはチャートと同じで答えしかないわけチャートと同じで答えしかないわけですから、1と2のどちらかができていなかったら間違いということになります。つまり、自分に足りてないものが何かを正確に把握することができ正確に把握することができるわけ把握することができるわけです。一通りチャートをやったら傍用問題集をやってみましょう。復習にもなるし、計算力もつけられるしで一石二鳥です！以上です。参考にしていただければ幸いです。1e:Tb60,一言でいえば「経験」です。 必要条件の利用は青チャートなどのいわゆる網羅系参考書などでは得られない少し発展的な技術ですが、数学がある程度得意な人は過去にやったことがあったり、習ったことがあったりとそれを利用した経験があるのです。 なので質問者さんももう少し経験を積めば普通に利用できるようになると思います。 ここで必要条件の利用に至るまでの思考回路の簡単な例を紹介しておきます。 問題 「k を正の整数とする. 5n^2 − 2kn + 1 < 0 ー①を満たす整数 n が，ちょうど 1 個であるような k をすべて求めよ.」 これは2008年の一橋の問題です。下にプロセスを書いてますが良問であり考えがいがあるので一回自力で考えてみてください。 まず大前提として数学における問題と解は全て必要十分性を保っている必要があります、従ってこの問題を解く際必要十分を保ちながら解く(同値変形)のと必要、十分を分けて解く2通りに分かれます。この問題では実数でなく整数の2次方程式であり同値変形で解くのはややこしい(できることはできます)と判断しまず必要条件から絞ろうと考えます。 この問題を考える際式①が成り立つとき5x^2-2kx+1=0(xは実数)が二つの異なる実数解を持つー②「必要」がある(つまり②は①の必要条件である)ことを利用します、そうすることによってkの条件が分かります。そのもとで①を満たす整数nがちょうど1個である条件は5x^2-2kx+1=0の二つの解(α、βとおく)の差が2未満ー③であればいいということがわかります。②と③から得られるkの範囲が5=0の2次関数が正と負にそれぞれx軸との交点をもつ\n↓\nf（0）<0\n\nのようにこれができれば後は基本の計算ができるだけでこの問題が解けます。\n\nこれを鍛えるためにはチャートなどで問題を解くときにどんな必要条件を使ってるか意識するだけでいいと思います。\n\nあまり注目されない点ですが少し意識を変えるだけで効果があると思います。"]}]]}],["$","div",null,{"className":"mb-4","children":["$","$L16",null,{"adviserImageUrl":null,"adviserName":"みかん","adviserDepartment":"大阪大学理学部","adviceId":"7hHjw2oBTqPwDZPu8hPs","numberOfFan":34,"clipsAvg":8.820512820512821,"adviceRateAvg":4.324324324324325,"profile":"大阪大学塾なし現役合格
