What is Math Anxiety? Math anxiety or fear of math is actually quite common. Math anxiety is quite 36 to stage-fright. Why does someone suffer 37 ? Fear of something going wrong in front of a crowd? Fear of 38 the lines? Fear of being judged 39 ? Fear of going completely blank? Math anxiety conjures(使现出) up fear of some type. The fear that one won’t be able to do the 40 or the fear that it’s too hard or the fear of failure which often stems(起因于) from having a lack of 41 . For the most part, math anxiety is the 42 about doing the math right, our minds draw a 43 and we think we’ll fail and of course the more frustrated and anxious our minds become, the 44 the chance for drawing blanks. Added pressure of having time limits on math tests and exams also cause the levels of anxiety to grow for many students. Where Does Math Anxiety Come From? Usually math anxiety stems(起源于) from 45 experiences in mathematics. Typically math phobias(恐慌症) have had math presented in such a fashion that it led to limited understanding. Unfortunately, math anxiety is often 46 poor teaching and poor experiences in math which typically leads to math 47 . Many of the students I’ve encountered with math anxiety have demonstrated an over reliance on procedures in math as opposed to actually understanding the math. When one tries to memorize procedures, rules and routines without much 48 , the math is quickly forgotten and 49 soon sets in. Think about your experiences with one concept — the division of fractions(分数). You probably learned about reciprocals(倒数) and inverses. In other words, ‘It’s not yours to reason why, just invert(反转) and multiply(乘)’. Well, you memorized the rule and it 50  . Why does it work? Do you really understand why it works? Did anyone ever use pizzas or math manipulative(巧妙处理的) to show you why it works? If 51  , you simply memorized the procedure and that was that. Think of math as memorizing all the procedures — 52 if you forget a few? Therefore, with this type of strategy, a good 53 will help, but, what if you don’t have a good memory. Understanding the math is critical. Once students 54 they can do the math, the whole notion of math anxiety can be overcome. Teachers and parents have an important 55 to ensure students understand the math being presented to them. 小题1: A.different B.similar C.far D.familiar 小题2: A.speech B.performance C.threatens D.stage-fright 小题3: A.understanding B.memorizing C.forgetting D.reading 小题4: A.poorly B.crazily C.well D.publicly 小题5: A.Chinese B.math C.English D.physics 小题6: A.wish B.conscience C.determination D.confidence 小题7: A.fear B.joy C.pleasure D.doubt 小题8: A.failure B.choice C.blank D.death 小题9: A.further B.greater C.less D.smaller 小题10: A.unpleasant B.unfair C.pleasant D.successful 小题11: A.because B.thanks to C.resulting in D.due to 小题12: A.fear B.anxiety C.failure D.misunderstanding 小题13: A.forgetting B.use C.understanding D.knowledge 小题14: A.panic B.excitement C.disappointment D.encouragement 小题15: A.opens B.works C.starts D.runs 小题16: A.so B.possible C.not D.any 小题17: A.Where B.Why C.When D.What 小题18: A.memory B.method C.brain D.body 小题19: A.fill B.realize C.confirm D.recognize 小题20: A.task B.aim C.appointment D.role
