Reducing Careless Mistakes in Science MCQ



" Practice does not make perfect,

Perfect practice makes perfect.


So its not about how many sets you do, its about how perfectly you do it. ' 

      This is what I always tell my students. You realised that your child is always stuck at the 40+ mark and can’t get past it? Or if not, they just can't seem to score full marks. 




      This is why. They are making the same mistakes over and over again. During mid terms, I looked through one of my A* attitude student's file. She is really hardworking and practice lots and lots of past year papers. (FYI - 2016 stack is already all done). However, she is still not scoring full marks. Something must be wrong. So I flipped through her papers and files and I realised one trend, she gets the same type of question wrong again and again. For her, its the graph on gravitational potential energy and kinetic energy kind of questions. She knows the concept and she could point out which is the correct answer. 
   
      Why is it that she doesn't get that question correct then? Simply because for that question, no working is done. 
   
     Doing things mentally is not smart.  Not for Science exams. Doing things only in their head is the birth of careless mistakes. 




Example of students' work below: 


His answer is 4 because he did not link what the question wants to the information in the graph. For instance, the question is asking for final length of spring Q and the graph is on extension. The working for himself is not clear enough. 

Question should be worked out in this way: 
What is the difference? The working is clear and that aids in checking of answer too. 

Nevertheless in exams, I wouldn't expect my students to write in this way. There is no time. How they will present their answer is with short form. 

eg.  Extended length = EL 
      Original length = OL 
      Total length = TL 

They have to remember this as well: TL = OL + EL 


So, do show this to your child, working is a MUST! It's not a good to have. 

This is the attitude to have when conquering MCQ!

Answers to PSLE Questions

Why do I write suggested solutions to Red Swastika 2018 SA1 Paper? - My students found it useful and requested for more!  - The parents who used it to help their child have found it useful!  That's why despite using 4 hours just to write ONE SET of the suggested solutions (Section B only) and doing the miscellaneous admin such as scanning, downloading documents, writing email to send out to our ISUN warriors, I do it.  Hope that all these will contribute to their learning :)  From the paper, there are quite a couple of questions from the PSLE Booklet: You can download the Red Swastika 2018 Paper here!  Red Swastika 2018 Q 30 Reproduction of Plants PSLE 2018 Q15 TEST IT OUT!  PSLE 2018 Q15 ANSWER  Red Swastika 2018 Q33 Adaptations PSLE 2013/ Specimen Paper Adaptions TEST IT OUT!  PSLE 2013/ Specimen Paper Adaptions ANSWERS Refer to other posts to learn more!

Respiration and Photosynthesis

Respiration and Photosynthesis With air quality going downhill, there may be chances that we need to carry plants around as our oxygen tank.  The working mechanism is based on 2 simple concepts of Primary 5 Science, Respiration and Photosynthesis.  As seen from the picture, the man is wearing a mask connected to the plant. As the man respires, it gives out carbon dioxide.  The carbon dioxide, together with water and light, the green plant with cholorphyll photosynthesises and produces oxygen for the man to respire and survive.   A summary of the both respiration and photosynthesis processes are below: Respiration Respiration is the breaking down of digested food with oxygen to produce energy. The equation of Respiration Sugar (from digested food) +  Oxygen (from inhaled air)   รจ  ENERGY (for body to use) +  Carbon Dioxide (to exhaled air) + Water Vapour (to exhaled air)  *NOTE* All living things respire includ...

3 Common Mistakes in P6 Forces

3 COMMON MISTAKES IN FORCES:  *Apologies that the alignment of this page is off & I can't seem to get it adjusted for now. If you want a downloadable worksheet, PM us at isuninfo@gmail.com *  1. Gravitational force (GF) vs Gravitational Potential Energy (GPE) Example 1 The ISUN warriors were playing at the corridor with a wooden ball. Xavier accidentally threw a ball and it travelled in the path as shown below rolling to a stop.   Which one of the following statements is correct? 1)       Gravity acted on the ball only when it travelled from Q to R. 2)       There are no other forces acting on the ball from P to Q except gravity. 3)       The amount gravity acting on the ball when it travelled from P to R is the same. 4)       The amount of gravity acting on the ball increased when the ball travelled from P to Q and d...
