In your work, determine a method for distinguishing the two varieties of midges. The Ice Problem Students at Woodward Academy were given a cup of water, a thermometer, and a stopwatch. Working in groups of three, they were to place a handful of ice in the water and measure the temperature of the water every ten seconds. Before they began collecting data, the students were asked to sketch their predications of what the graph of the data would look like. After making their predications, students conduct the experiment and then enter their data into their TI-82 calculators.
Students then attempt to find an equation that fits their data points.
The Perception of Change What began as a study of innovation in curriculum quickly evolved to include the study of change in teachers and their teaching. As the study progressed, we came to see change in a different light. We found that none of these satisfactorily captured the nature of the diverse changes we observed. The changes we observed were not always the same as those the teachers saw in themselves and their work. Teaching a different mathematics differently did not necessarily feel the way it looked to an observer.
