Why not only rely on past papers? In my opinion, the best preparation with past papers is not to look over mark scheme. Essentially, as the name suggests, mark schemes only aim to aid teachers to mark student’s work on his paper. Not only does it lack with the detailed explanation, but also students lose their opportunity to encounter real IB style questions if they rely too much on mark scheme. For section A questions it relatively gives a good explanation; for Section B questions, however, when things get lengthy, explanations tend to be very concise and often do not make sense for students. It solely aims to guide teachers to base their grading criteria; it is not built for a model of ‘worked solutions.’ I encourage students more to discuss their solutions with friends. Also, IB community is very strong among students via internet, such as IB survival and IB Facebook group page. It’s a good place to start a discussion. Let me give you an example why you should avoid the habit of relying your study with mark schemes: Example: This is one of my favorite questions from IB HL. It not only tackles on definition of functions, but also it requires students to understand the concepts on Topic 1 and apply their skills to ‘unseen’ questions. If we look at Part (d) (iii), it asks about giving area in terms of a certain function A. The first part of the questions asks us to find out the relation between Fn and its inverse; here students are required to know what inverse relation is. For the geometrical interpretation, functions that are inverse to each other are symmetric along y=x. Then the second part tests our inequality skills with algebraic and geometrical interpretation: For Part (d), if you realize in the square box of 1 by 1, Fn is less than x, which means it is below y=x from 0 to 1, and since we know its inverse must be symmetric by y=x, the inverse must be above y=x. From this aspect, we can draw a random 1:1 function and work with the area to derive an answer. I believe this is how a student should approach to this type of question, since this ‘interpretation’ of function’s inverse with its algebraic property of composition and geometrical property of symmetry is the key for the unseen question. Let us compare our approach with the mark scheme of the question: As you can see, it’s painfully concise, and students cannot obtain their logical processing of this question from the mark scheme. Yes, when you apply the numbers and methods given by the mark scheme you could get the answer. But you will lose the essence of ‘interpretation’ skills as well as the half-independent attempt on this nice question. You can always elaborate your answer if your logic is correct; that is one of the greatest tactics for IB maths exam. PARTIAL mark!
Marinna20 posted a topic in Maths StudiesHello, I'm writing a simple math paper for my Math Studies class and I'm in need for some data, I need 100 pieces of data at least. My paper is on determining wether speaking more than one language influences someone's memory capacity (Does it make them remember things clearly?) and so I'll compare that to people who only speak one language. I found a memory test online created by the university of Rutgers:http://www.memorylossonline.com/learning_memory/mem_games/verbaltest1.html If you guys could do the test honestly and then write your results on the comments along with amount of languages you speak FLUENTLY ex: comment results (or comment a screenshot of it) and next to results comment either 'monolingual' or "speak more than one language" It would mean a lot if you did this as I came late into the class and I really need these results please and thankyou
