Một số thông tin bổ sung về Math Test SAT
Thay vì kiểm tra thí sinh về tất cả khía cạnh của toán học, Math Test trong kỳ thi SAT yêu cầu thí sinh sử dụng các dạng toán mà thí sinh sẽ gặp phải trong hầu hết các tình huống thực tế. Các câu hỏi trong Math Test được thiết kế để phản ánh được khả năng giải quyết vấn đề, các vấn đề này thí sinh sẽ gặp khi theo học các chuyên ngành liên quan đến Toán Học, Khoa học tự nhiên, và các kiến thức toán học này còn có thể phục vụ cho nghề nghiệp/ chuyên ngành thí sinh đang theo học hoặc sẽ làm sau này.
Để hiểu rõ hơn về việc giải quyết vấn đề toán học là như thế nào, sau đây sẽ là một ví dụ cụ thể được trích từ một bài thi toán SAT (phần thi không dùng máy tính):
Question: A start-up company opened with 8 employees. The company’s growth plan assumes that 2 new employees will be hired each quarter (every 3 months) for the first 5 years. If an equation is written in the form y = ax + b to represent the number of employees, y, employed by the company x quarters after the company opened, what is the value of b ?
Một công ty khởi nghiệp thành lập với 8 nhân viên. Kế hoạch phát triển của công ty giả định rằng cứ mỗi quý (3 tháng) sẽ tuyển 2 nhân viên mới và tuyển như vậy trong vòng 5 năm đầu tiên. Nếu phương trình ở dạng y = ax + b để biểu thị cho số lượng nhân viên , trong đó y là số nhân viên được tuyển trong x số quý sau khi công ty mở. Tìm giá trị của b?
Bài giải:
x : tổng số quý sau 5 năm là 5 x 4 = 20 quý
Trong 20 quý này sẽ tuyển 20 x 2 = 40 nhân viên
y: tổng số nhân viên từ khi thành lập đến 5 năm sau là 40 + 8 = 48 nhân viên
Ta có phương trình: y = ax +b
48 = 2×20 + b
=> b = 8
Từ ví dụ trên có thể thấy rằng bài thi toán không chỉ đơn thuần là áp dụng công thức để tìm ra được đáp án, mà trong bài thi sẽ có những câu hỏi cần suy luận và cần phải phân tích kỹ thông tin thì mới giải được bài.
Thí sinh có thể dựa vào 3 bước sau đây để giải quyết các bài toán:
Bước 1: Xác định yêu cầu của bài. Ở bước này thí sinh có thể gạch chân, khoanh tròn các thông tin mấu chốt và xác định xem đề bài đang hỏi gì.
Bước 2: Sắp xếp những thông tin vừa khoanh để phân tích và tìm ra câu trả lời. Ở bước này thí sinh phải dựa vào từng dạng câu hỏi:
- Đối với dạng bài đại số có câu hỏi ngắn, ít thông tin, thí sinh có thể lược qua bước 2 và đi thẳng vào việc tính toán, giải phương trình bằng cách áp dụng các công thức toán đại số. Dạng bài này thí sinh cố gắng vận dụng các thủ thuật toán và thực hiện thao tác cộng, trừ, nhân, chia, hay thay số để tìm ra câu trả lời từ phương trình đề bài cho.
- Đối với dạng câu hỏi đoạn văn, thí sinh nên phân tích từng cụm từ để quy những thông tin đó ra thành phương trình, sau đó giải phương trình để tìm ra đáp án. ( xem lại bài ví dụ phía trên)
- Đối với dạng bài hình học, thí sinh nên viết lại tất cả các thông tin lên hình và tìm kiếm các manh mối mà hình cung cấp. Nếu đề bài không cung cấp thì thí sinh phác thảo hình để dễ hình dung và giải câu hỏi hơn. Lưu ý: không nên dành quá nhiều thời gian cho 1 câu, khi cảm thấy đã tính qua 1,2 lần vẫn chưa chọn được kết quả thì nên làm qua câu tiếp theo và sau đó quay lại làm những câu còn phân vân cuối cùng.
- Đối với dạng bài diễn giải số liệu liên quan đến biểu đồ hay đồ thị, thí sinh cần phân tích kỹ tên và thông tin các trục, đơn vị mà đề bài cung cấp để tìm ra câu trả lời.
Bước 3: (dành cho câu hỏi multiple-choice) Sau khi thực hiện xong bước 1 và 2, thí sinh xem xét các đáp án và chọn ra đáp án trùng khớp với kết quả vừa tìm được. Trong trường hợp không khớp đáp án, thí sinh làm lại bước 2 lần nữa và phân tích loại ra các kết quả bất hợp lý.
