Print this page In Grade 3, instructional time should focus on four critical areas: Students develop an understanding of the meanings of multiplication and division of whole numbers through activities and problems involving equal-sized groups, arrays, and area models; multiplication is finding an unknown product, and division is finding an unknown factor in these situations. For equal-sized group situations, division can require finding the unknown number of groups or the unknown group size.
Posted on November 30, by Scott Alexander [epistemic status: My bias is against the current college system doing much good. I have tried not to be bogged down by this bias, but take it into account when reading my interpretations below.
An earlier version of this post claimed that one paper had shown a u-shaped relationship between time spent in college and critical thinking.
A commenter pointed out this was true only of a subset in two-year colleges, but not of four-year colleges or college in general — which shows the expected linear relationship. I am sorry for the error, and correcting it somewhat increases my confidence in college building critical thinking.
The evidence sort of supports him, but with the usual caveats and uncertainties. First of all, what the heck is critical thinking? Luckily, we have a very objective scientific answer: Most studies on this issue are terrible because they lack control groups. That is, they measure students when they enter college, measure them again when they leave college, and find that their critical thinking ability has improved.
But this could be for any number of reasons. Maybe older people generally have better critical thinking than younger people. Maybe life experience builds critical thinking.
Maybe college had nothing to do with any of it. The best meta-analysis of such studies, MacMillanfinds exactly this, and concludes: Overall these studies suggest that seniors, in the main, are probably better at critical thinking than freshmen.
However, since the most compelling data were gathered through weak pretest-posttest or longitudinal designs, it is difficult to separate out the effect of college from the maturational effects that occur despite college.
But in any case we need a better study design to conclude anything from this. There are two studies with moderately good designs, both by a guy named Pascarella.
The first compares 30 college students to 17 matched non-college students and follows them up for one year. The secondlarger study compares students doing college full-time to students doing college part-time, under the theory that if college is causing the effect, then a little college should cause a small effect, but lots of college should cause a big effect.
They find this in the four-year college sample, and a garbled u-shaped mess in the two-year college sample. At least the four-year sample, which is what most people are interested in, looks good. On the other hand, some other studies find less impressive effect sizes.3/04/ Grade 3 Math Unit Title Unit 3: Multiplication and Division Time frame 5 weeks 21st Century Themes Critical Thinking and Problem Solving Communication and Collaboration ICT (Information, Communications and Technology) Literacy Flexibility and Adaptability Initiative and Self-Direction Productivity and Accountability.
