Assessment Strategies--all formative for this POE
Prior to beginning:
Ask students what they remember about electricity and batteries.
Let them play with batteries, light bulbs and small electronic gadgets.
Do students remember/rediscover that batteries have a positive and negative end?
How do they explore--just one combination or several?
What are they talking about and showing each other as they play?
Do they work together to create new ideas/combinations?
Do they answer one another's questions?
After first penny battery cell has been demonstrated:
Ask students to predict what stack combination will make the strongest battery.
Do the students understand what has been asked of them?
Are the students following classroom procedure and writing down/drawing/labelling their predictions?
Are the students giving up after one stack or do they keep trying other combinations?
Are they simply copying one another or coming up with unique combinations?
Are the students able to explain why they think their combination will work?
And are they able to explain why they think a certain combination did not work? What will they change?
Summative might include making a working penny battery however this is like using an algorithm: They can follow the steps but do they truly understand how a battery works?
