Physics High School statistics are dissappointing in many respects.
Few know that even such a main and relatable concept as velocity is not well understood technical, which is 80% of its scientific conception. Students cant get themselves thinking is such manner and they miss all the magic i this topics physics
One idea I have is ask students from what distancefrom roadside trashpin should one drop trash, if in speed ing car of 20m/s (70km/h) to not miss and thus spoiling the environments. This might help getting them to think in the genuine physics behind the concept
Any ideas? Comments?
I'd like to know where you've got the numbers. It's just a hypothesis this 80% (or 85%) of not understanding the difference between speed and velocity? Which is the area where this come from? a region in your country? your whole country? all of Europe? the whole world?
I'm a teacher of natural sciences in high school, being physics my prime area of expertise. It's really easy to make some activities outside the classroom to make the vectoring more easily to understand. When each group of work traces a route around the yard and draw it, your done! Nobody will forget what a vector is and that velocity is a vector.
Velocity can be defined as Ratio of Distance Travelled by Time taken.
S.I Unit of Velocity is Meter/ second.
This is the Simplest Explanation .
David Portius i got that insight from education seminars, it was a big % and i think it was about satisfactory understanding of the concept, i.e not just rough grasp but in dept. You can search 'teaching velocity" or "velocity concept understanding" in educational research for accuracy
