Teachers' gestures boost math learning - 0 views

  • The problem involved mathematical equivalence (i.e., 4+5+7=__+7), which is known to be critical to later algebraic learning. In the speech-only videos, the instructor simply explains the problem. In the other videos, the instructor uses two hand gestures while speaking, using different hands to refer to the two sides of the equation. Students who learned from the gesture videos performed better on a test given immediately afterward than those who learned from the speech-only video. Another test was given 24 hours later, and the gesture students actually showed improvement in their performance while the speech-only students did not.

    A recent study shows that students learn math better when their teacher employs hand gestures in the lessons.  Though the study itself was done on a basic addition problem, the idea of using gestures in the classroom could be utilized in higher-level math classes as well.

Truly Singaporean Singapore Mathematics: [Pri20150522RPRW] More Hands make Light Work? - 0 views

  •  When we add up the given rates, we get  1/5,  which is the rate that 2 Ahmads, 2 Kumars and 2 Calvins would work.  Unfortunately we do not have the clones.  We just have one Ahmad, one Kuman and one Calvin.  So we divide that by 2 to get  1/10  and this is their combined rate.  This means that they can complete  1  house in  10 days.
