Having served as a teacher for a long period of time at this educational institution with students from over 80 countries, I realised the above-mentioned view was shared by other students, too, who had to change the medium of instruction to English. This does not seem to make sense as one would have expected mathematics to be the easiest subject to follow as it has its own symbolic language. Why then has this situation arisen?<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">I would like to separate these difficulties into two categories:<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">1. Hastiness due to mindset<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">2. Vocabulary issues<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">Sometimes hastiness can automatically occur due to the mindset that mathematics should be easy to follow even if you change the medium of instruction as you are dealing with symbols. This attitude can cause enormous problems as students may skip instructions or avoid reading the question fully and concentrate only on the symbolic part of the problem<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">As an example, consider the following question.<\/span><\/p>\n<p align=\"LEFT\"><!--more--><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><em>The graphs of lines 3y = 5x + 1 and 2y = 7 \u2013 3x intersect at point P. Find the coordinates of P.<\/em><\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">Seeing the word \u2018graphs\u2019 and the two equations, a student maybe tempted to draw the graphs of the two lines and thereby find the point of intersection, which is a time-consuming affair. If it was read properly, the student could have noticed that the solution can be obtained by solving the two equations algebraically, which is much more efficient.<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">To a fast reader, obtaining the correct answer to the following question can be a problem as it may end up with just finding the value of x.<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><em>If 2x+3 = 5x-3, find the value of 2x+3.<\/em><\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><strong>The students need to be trained to read the question fully and understand what is required to be done, before attempting it.<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span lang=\"EN\" style=\"font-size: 16px; color: #000000;\"><b><\/b><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-70175 alignleft\" src=\"https:\/\/websitedesigns.com.au\/elankanew\/wp-content\/uploads\/2021\/07\/English-in-Mathematics-2.jpg\" alt=\"English in Mathematics\" width=\"350\" height=\"1025\" \/>The time spent to grasp the aim of the question is not wasted time.<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">Many children consider mathematics as an alien language consisting of symbols and expressions. Most of the difficulties that students encounter is related to vocabulary. The mathematical interpretation of the meaning of a word may differ from the meaning given to it in the English language. The word \u2018find\u2019 in mathematics means to obtain an answer showing the working while in the English language, it refers to discover or search. The following sketch shows the funny side of this difference.<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">Two of the words that has caused much confusion are \u2018or\u2019 and \u2018and\u2019.<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">In general usage, A or B is considered as either A or B but not both, as shown in picture.<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">However, in mathematics \u2018A or B\u2019 means \u2018it can belong to A or B including intersection\u2019. This is shown in picture.<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">The above, in normal usage is interpreted as \u2018A and B\u2019. However, in mathematics A and B refers to only what is common to A and B as shown in picture.<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">Here are the mathematical meanings of some of the other words which can have a different meaning with the English language definitions.<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><strong>Determine<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span lang=\"EN\" style=\"font-size: 16px; color: #000000;\"><b><\/b>\u2013 Obtain the only possible answer<b><\/b><\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><strong>Plot<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span lang=\"EN\" style=\"font-size: 16px; color: #000000;\"><b><\/b>\u2013 Mark the position of points on a diagram<b><\/b><\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><strong>Write down<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span lang=\"EN\" style=\"font-size: 16px; color: #000000;\"><b><\/b>\u2013 Obtain the answer (Working need not be shown)<b><\/b><\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><strong>Constant<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span lang=\"EN\" style=\"font-size: 16px; color: #000000;\"><b><\/b>\u2013 A number that does not change<b><\/b><\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><strong>Similar<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span lang=\"EN\" style=\"font-size: 16px; color: #000000;\"><b><\/b>\u2013 Having the same shape but not the same size<b><\/b><\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><strong>Deduce<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span lang=\"EN\" style=\"font-size: 16px; color: #000000;\"><b><\/b>\u2013 To show a result using known information<b><\/b><\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><strong>Operation<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span lang=\"EN\" style=\"font-size: 16px; color: #000000;\"><b><\/b>\u2013 A procedure such as addition, subtraction, multiplication, etc.<b><\/b><\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><strong>Element<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span lang=\"EN\" style=\"font-size: 16px; color: #000000;\"><b><\/b>\u2013 A member of a set<b><\/b><\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><strong>Volume<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span lang=\"EN\" style=\"font-size: 16px; color: #000000;\"><b><\/b>\u2013 The extent of space occupied by a solid<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">The following illustrate some of the difficulties that the difference of meanings brings:<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\"><em>How odd these odd numbers are?

Let me write it on the board.<\/em><\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">The polysemous nature of some of the mathematical terms make it confusing for the students in the understanding of mathematical concepts. Mathematical terms have precise definitions to describe numerical relationships. At times these definitions resemble the everyday usage meaning but there are instances where the definitions notably differ. Consider \u2018in general\u2019 as an example. In mathematics there can be no exceptions to a result if it is considered to hold in general. However, in everyday usage, if a claim is said to be true in general, it would mean that it is true most of the time, but exceptions are possible.<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">To add to the problem, there are some terms such as \u2018degree\u2019 that can have many different meanings within mathematics while having a different meaning in everyday use. In mathematics, degree can refer to the measurement of an angle, the complexity of an algebraic equation and a unit of temperature.<\/span><\/p>\n<p style=\"text-align: justify;\" align=\"LEFT\"><span style=\"font-size: 16px; color: #000000;\">Although mathematics deals essentially with symbols, it is taught through the medium of language which is the major means of communication. Students build understanding as they process ideas through language.\u00a0<b>It is important for students to give emphasis to the familiarisation with the mathematical vocabulary and at the same time understand the difference of meanings of terms mathematically and everyday usage.\u00a0<\/b>Teachers have an important role to play here in highlighting such terms and using them in different contexts for comfortable acclimatization. As Marcus Quintilianus quoted, \u201cOne should not aim at being possible to understand, but at being impossible to misunderstand.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"
