Explain the entire process using algebraic terms such as expansion, subtraction, addition, grouping of like terms
During a tree planting event, a group of boys and girls planted a total of 148 trees. Each boy planted 7 trees and each girl planted 5 trees. If the number of boys are 4 more than the number of girls, how many boys were there?
Viva voce always have been a problem for me as I always have a hard time to explain to people clearly. Though this problem was very easy, it was the explaining part that makes the task a whole lot tougher. I have learned to properly assess the whole problem and using mathematical terms to explain how did I do the problem. My voice and idea must be clear to address the problem. The reason I used screen record as it will be clear for the listeners to see and hear instead of filming where the camera will be moving. It was an enjoyable time to convey my thoughts into words and visuals and it was fun overall.
Although this vivavoce performance task seemed to look easy, in actual fact, it was quite difficult. I had to think very thoroughly on how to explain every step. Although the question was pretty easy to do, it was a challenge to convert my thoughts into words. I learnt that in order to convey my thoughts well, i could not be hasty, i had to think of every single detail.
Secondly, i took around 2 minutes to decide on what platform to use. I decided that filming would still be best, as it will be easier for the viewer to understand as it is also easier for me to explain.
Another challenge i found was that i had to make sure the visuals were visible and understandable. I took time to write down the workings with details, and set my camcorder angle perfectly on the tripod and zoom in just enough. I even had to adjust the lighting of my camcorder's flash by putting pieces of scotchtape in front, as i was casting shadows onto the foolscap. (i was running out of time as the battery time was draining fast. D': )
Lastly, sorry for poor video quality. (haha)
I learnt to not leave my work to the last minute even though it might be easier to complete as in this assignment, even though the questions are quite easy to solve, I had problems trying to do the explanation of my solution to the question.I also learnt to apply past knowledge like algebra techniques.
The challenges I faced were having to record while my grandmother was watching the television with my brothers, finding a way to explain clearly what my solution was all about so that the viewers can understand what i had written and my method of solving it.And, another challenge is to find ways to edit my video so that it can be improved.
From this experience of this performance task, I have learnt not to leave my work to the last minute and rush everything at the eleventh hour. I also learnt that even though it can be very easy to do the question, putting the explanation into words for others to understand is much tougher.
I faced quite a number of challenges in this performance task. The one by far the worst and most difficult challenge was that I did not have my learning device to do this performance task, so I had to use my computer at home which was Windows, and I have grown unaccustomed as to how to use Windows after using the learning device for all this time. I had to use Windows Movie Maker to create my video and I also found that challenging as I was used to using iMovie for creating my videos. The next thing was my time management. I had the I&E camp on thursday and friday, so that took up 2 full days and by the time I reached home, I was too tired to do any of my homework. I forgot all about the performance task until today, and so had to rush to complete it.
*Sorry, this is the link to my video on youtube, my blogger has some inefficiency.
Reflections: In this Performance Task, i realise that although solving a question may be easier, describing on how to solve it to another person is many times more difficult. Along with that, I had to talk a lot faster and clearer to get my message across. As such, to do a viva, one must fully understand the question and methods on how he or she solves it, following speaking in a clear and precise order. This has taught me to carefully solve the question with every step written, not skipping one such as to be able to explain it.
Learning Points: From this project I have learnt that explaining a solution for a question is much harder solving a question. Though we have to use the same steps and answer, we have to turn our answer into something vocal and others can understand. We must explain every single step and find the reasoning behind the working. When we solve question, we have formulas and mental calculation already in our heads, but in explaining it, it is one whole different story. We have to think and think how our steps are done and the reasons and concepts behind it. We have to make the workings into something even young children can understand.
Challenges: I faced a couple of challenges in this project. I used paper and pen to show my workings instead of some other classmates who used multimedia platforms to display their workings. Since I decided to point out which working I was explaining so the audience would not get lost, I had to keep looking at both the paper and the soft-copy script I made. I had to co-ordinate my eyes with my hands, and multi-task. I also faced problems when trying to keep the paper in view of the camera, and not let it bend at the edges so the audience can see my workings, since I was already desperately trying to focus on both my pointing and the script. I also said some things wrongly in the video, so I am not very happy with it.
From this performance task, I learnt that explaining solutions isn't that easy especially when your objective is to make it simpler for people to understand.
Most of the challenges I faced was technical difficulties such as the audio as my voice wasn't audible and my hand kept on shaking as I took the video. There were also distractions as sounds from the neighbors.
In overall, I enjoyed making this although there were a lot of challenges in the way.☺
From this mini performance task, I learnt that explaining your questions is not that easy,sometimes,you just can't turn your thoughts into words.
Most of the challenges i faced was technical difficulties such as the audio,i also faced a little bit of problem when trying to solve the question it self during the balancing part as i am not too sure which is the right way.
Overall ,this has been a fun performance task to me and i enjoyed explaining.
I have learnt that doing a question is easy, but explaining it is not! When you do a question, you only have to 'speak' in your mind, but when you explain, you have to make sure that the other person can understand it, which is extremely hard as some words/methods are hard to express.
I had some problems editing my video, as I had to time the different pictures according to the audio, and it takes up a lot of time. Also, to express some things in my head so that others can understand it was a bit of a challenge, as it is rather hard.
From this Viva Voce,I have learnt that the question may be very easy just working out the methods and get the answers and only you need to understand it since you are the one who are doing it. However when it comes to explaining,you need to explain why you do this step,how you derived to this answer. The audience might not understand why must this step be done thus you have to explain the formula. However you might not know the formula as normally you only have to accommodate to one person and that's yourself so you don't need explain. Thus when it comes to explaining to others,you will have trouble trying to state the explanation.
Challenges I have met while doing this Viva Voce is to figure out whether this is mathematically correct when I do this step or even if the working is right. Am I using the correct signs or methods to do the questions. Also having trouble to find out the meaning behind the formula to explain to the people.Regarding recording problem as I want to record all in one go,when I make a mistake I have to re-record again and I record for about 5-6 times even though I have my own script.
I faced some challenges such as video problems, inability to upload the video properly, my voice facing problems.
Finally, I faced some problems with uploading the videos. I tried many ways and found a way to upload the video properly. In the end, I succeeded.
S1 (Viva Voce) Part B Reflection
I had faced many challenges when I was editing the video and recording my voice. During recording, I was unable to find the proper term to describe the steps and I sometimes read cm as m and m as cm, so I had to re-record everything . Also I had to match the voice to the word equations that were appearing on the screen.
Some of the things I had learnt was that not only the explanations was important for a maths question but also the visual to let one understand it better.
Part B (Reflection) :
It was difficult trying to make my handwriting 'visible' in the video considering the fact that my Mac didn't have good definition... I managed to flip the video in iMovie though. I realized i actually had I calculation error at Part 3 so I had to redo that part. I think I talked abit fast especially when nearing the end of the video. I also had problems trying to make my video sound more 'professional' by using more terms. I was also hesitant on whether or not to go deeper into explaining algebraic terms in linear equations. So I just roughly explained using a more hopefully understandable method by adding two terms at the side.
