1b:T11b7,はじめまして。 確かに問題を見て解法が思いつくようになったら試験の場においては最強です。ただ多くの受験生はそれが直ぐには出来ないので、ひたすら問題を解いて(書いて)定着させます。さかさんはもしかするとこのレベルは脱しているのかもしれません。しかし今高１ということでこれから新しい単元に突入し、新しい概念や解法をたくさん学ぶことと思います。その時になったら、定着させるために嫌でも書く作業は増えてきます。 また書くことのもうひとつのメリットとして、書いてみて(解き進んでみて)初めてわかることもあります。人間の思考力の容量は意外と小さいです。本来書くという作業はそれを補うもので、脳内の情報を書き留めることで思考力のキャパが空き、また次の段階に行けます。今は基礎の問題ばかりだと思うのでこのような状況に陥ってないとは思いますが、上と同様必ず陥る時が来ます。具体例として、与えられた式が難しくて手が出せなくても、色々いじくっていると解法が見えた、ということもあります。 結局の所、現在に限ったことを言うと、扱っている内容がしっかり理解出来ていれば問題ないと思います。ただそれはあくまで現段階であり、いつかはそうはいかない(書かなくては次に進めない)状況になる、ということさえわかっていれば大丈夫だと思います。 参考として私が受験生の時にやっていた勉強法を一部紹介します。 英語について。現役の時はひたすら問題集を解きまくっていました。しかし元々記憶力がいいほうではなかったこともあり、全く体系的な知識が得られず、全然成績が伸びませんでした。そこで浪人中はまず理解するところから始めました。参考書を何冊も用意して、自分が納得が行く(試験で通用する)理解が得られるまで読み込みました。その間は全く問題集を開きもしませんでした。結果浪人中は問題集を1冊もやりませんでしたが、センターは9割取りました。過去問も長文以外やってません。要するに問題ばかり解いてもとても非効率なので、まず本質的なところを理解した方が効率的に成績が伸びるということです。アウトプットをいくらしてもインプットがしっかり出来てないと意味がなさないということですね。 数学について。正直数学は参考書とか漁っていると分野ごとにしっかりまとめられていることが多いので、参考書を見るのがオススメです。私は予備校の授業を利用しましたが、その代替として参考書があります。特にチャート式を使っているのならば今のところ問題ないと思います。ただ分野を超えた内容はしっかり対策しました。なぜならそこが入試で問われるからです。例えば整数や確率漸化式などです。整数は高校では習いにくい(内容自体は初等の方の物だから)にも関わらず、大学によってはとても難しい問題を出してきます。確率漸化式は確率と漸化式(数列)の理解を同時に使えば問題なく解けるのですが、多くの受験生はそのような思考回路がなく現役生の苦手分野となってます。どちらも高校では扱いにくい分野かつ入試必須なのでしっかり体系化して対策しました。整数は、考え方自体はシンプルで多くはありません。従ってパターンを蓄積していれば対応できます(どう組み合わせたり扱ったりするかには訓練が必要)。確率漸化式は先も述べたようにそれぞれの分野の理解を同時に使えるように訓練しました。個別的な話になりましたが、まず知るべきことを知ってから問題演習をすべき、というところは英語と一緒です。 もう少し細かい話があったら個別で対応します。 まだ高１なので時間はありますが、しっかり指針をもって勉強しているのは立派だと思います。なかなかできる人はいないです。その調子で頑張ってください。1d:Tf02,センター試験の集合は、実数の集合を扱うことが多いため、数直線上に図示するのが有効なことが多いです。 目盛の間隔を正確に図示する必要はなく、それぞれの端の大小と、黒丸白丸があっているかが重要です。(黒丸の場合はその点を含む、白丸の時はその点を含まないことを表します。不等号に=が入っているかどうかの違いとも言えます。) 例えば、 p: x>1 q:x≦2 のように与えられていた時、右向きの数直線上に左から1と2の点を書きます。 pについては、x>1(つまり「xは1より大きい」)であることから、先ほど書いた1の点に白丸を書き、そこから右上がりに少し直線を書き、そこから右向きに直線を伸ばします。新幹線のような形になります。この形は、1の点を含まないことを表すもので、白丸と同じ意味ですが、ぱっと見で分かるように両方使います。また、この線がpであることをどこかに書いておいてください。 qについては、x≦2(つまり｢xは2以下｣)であるので、2の点に黒丸を書き、そこから真下に少し直線を書き、左向きの直線を伸ばします。こちらは、電車のような形になります。この形は、2を含むことを表すもので、黒丸と同じ意味です。こちらの線にも、qであることを書いておいてください。 このように、範囲を一つ一つ図示していくと、次のようになります。 _______________ p / 2 ---------○-----●------->x 1 | q --------------- これを見れば、「pかつq」や、「pまたはq」「p⇒q は真か偽か」はすぐに分かるはずです。たとえば｢pかつq｣なら、pとqが重なっているところなので、1
