Description:
This paper critically examines the discrepancies among the pre-requisite fractional concepts assumed by a curricular unit on operations with fractions, the teacher's assumptions about those concepts and a particular student's understanding of fractions. The paper focuses on the case of one student (Tim) in the teacher's 6th grade class who was interviewed by one of the authors once a week during the teaching of the unit. The teaching materials and the teacher's instruction were based on the assumption that students understood the concept of a unit fraction as being one of several equal parts of a given whole. The teacher neither emphasized the need for equal parts nor the part-to-whole relation. The teacher's reasonable assumptions about her students' understanding of fractions were severely challenged by the cognitive constructs that Tim exhibited during his first two interviews. When she viewed tapes of the class instruction and the interviews with Tim she realized Tim lacked essential constructs to make sense of her instruction. She subsequently made adjustments in her instruction, making effective use of more appropriate representations based on tasks from the unit that we modified and used with Tim in our interviews. These adjustments helped Tim to construct partitioning operations and an appropriate unit fractional scheme. This study illustrates the importance of coming to understand a student's mathematical activity in terms of possible conceptual schemes and modifying instructional strategies to build on those schemes. The coordinated design of the research study facilitated these instructional modifications.

well, at least 10.

100 Women I think is a follow up to 100 Girls which was a movie I loved and when I heard this was somewhat a sequl, I threw it over the counter of Blockbuster.

So this guy loses his girlfriend and is having a bad day and he meets this chick who was fun, exciting and made him laugh (gotta love a women who just takes her bra off to make a sling shot to fling rocks at the guys ex girlfriends window..whoops, spoiler...euh, sue me)

And after they have spent the eveing having fun, she gives him her phone number and she goes home. But the guy loses the phone number on behalf of the rain... so he decides to become a delivery boy in hopes he will find her. (hey, its what you and I would do, right?)

And eventualy he finds his fair maiden... only something happend and shes all depressed and doesnt wana know him. So he bugs her everyday and then accidently falls in love with her best friend and then then the end wasnt qiet what I thought it shoudl be, but heh, what can you do?

The movie is funny, sweet & romantic but not overdone in that mushy way, its done so that even the guys will enjoy this film... unless your a neanderthol who beleives Rambo is the most romantic movie ever.

The humor is great, original (i think) and moves along nicely I thought.

Give it a rent at least, it's not gonnah kill you.
