class size

  • Smaller class size seems to result in higher achievement among students who are economically disadvantaged. Students with lower academic ability seem to do better in smaller classes than in larger ones. It may be that class size affects student attitudes more significantly than it affects achievement. A direct effect of large class size is to lower the morale and increase the stress of teachers. There is typically little to be gained from reductions in class size that do not bring class size below 30.
  • Smaller classes are beneficial for children at the primary level, particularly in math and reading.
  • The most positive effects of small classes on pupil learning occur in grades K-3 in reading and mathematics.

  • Little, if any, increase in pupil achievement can be expected from reducing class size if teachers continue to use the same instructional methods and procedures in the smaller classes that they have used in larger classes (Robinson, p. 82).
  • Teachers with small classes must not only be trained to be effective in such settings, but they must also be committed to try new skills and procedures.
  • Robinson, Glen E. “Synthesis of Research on the Effects of Class Size.” EDUCATIONAL LEADERSHIP (April 1990): 80-90.
  • The most recent comprehensive review of existing research was completed by Robinson (1990), and used a cluster analysis approach. Studies were “clustered” into categories considered important for class size decisions such as grade levels, subject areas, student characteristics, student achievement, student behavior, and teaching practices. The results of part of Robinson’s analysis appear below.
  • Effective schools research has extended its research agenda by focusing on an expanded number of variables that are presumed to be related to student achievement. Schools are now perceived as a cultural entity where the complex interplay of multiple variables affect the lives of all who learn and teach in those institutions. As the metaphor for American schools has shifted from an assembly line to that of a caring, learning community, the class size research agenda has also shifted to include such variables as instructional method, teacher morale and stress, teacher work load, student behavior and attitudes, content areas, student characteristics, and grade level. Bennett (1987), in a review of more recent research, found broad agreement among researchers on the following general conclusions:

  • Game designer Marc LeBlanc has defined eight types of fun: sense-pleasure, make-believe, drama, obstacle, social framework, discovery, self-discovery and expression, and surrender. Paul Ekman, a researcher on emotions and facial expressions, has identified literally dozens of different emotions - it’s interesting to see how many of them only exist in one language but not in others. Nicole Lazzaro did some studies watching people play games, and she arrived at four clusters of emotion represented by the facial expressions of the players: hard fun, easy fun, altered states, and the people factor.
  • Games are not stories. It is interesting to make the comparison, though: Games tend to be experiential teaching. Stories teach vicariously. Games are good at objectification. Stories are good at empathy. Games tend to quantize, reduce, and classify. Stories tend to blur, deepen, and make subtle distinctions. Games are external - they are about people’s actions. Stories (good ones, anyway) are internal - they are about people’s emotions and thoughts. In both cases, when they are good, you can come back to them repeatedly and keep learning something new. But we never speak of fully mastering a good story.
