Step 1: Identify a feature for comparison The ToC Framework TM or Table of Comparison helps you compare similarities and/or differences between two or more things in a structured manner and meet the marking criteria for ‘compare’ questions.Ī ToC for comparing 2 objects is shown below. One of the ways to show similarities and/or differences using Learnable’s ToC Framework TM to construct a specific and relevant response. Ĭompare requires similarities and/or differences whereas ‘contrast’ requires differences only. When answering ‘compare’ questions, students are required to show similarities and/or differences between two or more things. The NSW Education Standards Authority defines ‘ compare’ as “ show how things are similar or different.” To answer ‘compare’ physics questions, you must first understand the meaning of the verb, ‘compare’. What is the process for answering ‘compare’ Physics questions? Quantitatively compare the mass and weight of a 70 kg person on the moon and on Earth.Ĭompare the operations of a brushed DC electric motor and an AC induction motor. (b) The acceleration due to gravity on the moon is 1.6 m s –2 and on Earth it is 9.8 m s –2. (a) Compare the force of gravity exerted on the moon by Earth with the force of gravity exerted on Earth by the moon. The loop is then allowed to rotate by 90° about the axis PQ.Ĭompare the forces acting on WX and XY before and after this rotation A current flows through the loop in the direction shown. Source: NSW Education Standards AuthorityĪ metal loop, WXYZ is connected to a battery and placed in a uniform magnetic field. QuestionĬompare qualitatively the relationship between force and distance in the graphs. Examples of ‘compare’ questions with different marks are listed below. Marks allocated for an ‘compare’ long response question can vary from 2 to 6 marks. There are two main types of compare questions asked in HSC Physics exams:Įxamples of ‘compare’ questions in Physics exams There is always one or more ‘compare’ question in the HSC Physics Exam. But it’s also the question type students can lose marks easily without knowing. Types of ‘compare’ long response questions in the HSC Physics ExamĬompare physics questions are perceived to be relatively easy to answer. Sample ‘compare’ long response questions and answers using the ToC Framework.The process for answering ‘compare’ Physics questions.‘How to answer ‘compare’ Physics questions’ is a comprehensive guide for students on how to develop a structured scientific response that is specific, relevant and comparative. Most students struggle to identify the comparative features and provide irrelevant and non-comparative response. Students find ‘compare’ Physics questions tricky to answer. For example, INT_MAX - (-1) = INT_MIN suggests that INT_MAX is smaller than -1 (technically, the overflow leads to undefined behavior, but let's assume modulo arithmetic).Answering ‘compare’ long response questions This trick cannot work to compare integers, because the difference between two integers generally does not fit into an integer. (Note that this assumption does not hold for systems where sizeof(char) = sizeof(int).) This works because the difference between two characters is generally assumed to fit into an integer. Implementing the compare function for characters is quite easy you simply subtract the arguments: int compare_char(char a, char b) This function is often used to parameterize sorting and searching algorithms from standard libraries. Otherwise, a and b are equal, and the result is zero. If a is bigger than b, the result is some positive integer. If a is smaller than b, the result is some negative integer. The compare function is a function that takes two arguments a and b and returns an integer describing their order.
