DIDACTICSTEACHING VIA PROBLEM SOLVING13. What sort of "action" is involved in a percent problem? Look through a textbook (.for other topics for which the "action" is somewhat abstract.14. Mr. Denson:You:"I've tried assignments with more thanthem. The kids just couldn't do them.with only one type."one type of word problem inSo now I use assignments15. Teacher: "Whether you call problem solving the star of the curriculum or theheart of teaching, fancy (<strong>and</strong> mixed) metaphors don't make problemsolving any easier. I've found that my students can't do word problemsat all, so I just skip them. The kids can learn how to do wordproblems in high school."You:16. Talton [1973] suggests stressing these reading skills to improve performance onword problems: selecting main ideas, making inferences, constructing sequences,following directions for simple <strong>and</strong> complex choices, <strong>and</strong> reading maps <strong>and</strong> graphs.Plan how you might stress some of those skills. (See also Reading in Mathematiasin the resource Ratio, Proportion <strong>and</strong> Scaling, <strong>Mathematics</strong> Resource Project.)17. Schwieger [1974] has listed eight components which he believes to be basic insolving mathematics problems. Examine some problems to see whether his componentswould yield a solution. Here is his list:a. CIassify: to recognize pertinent characteristics <strong>and</strong> attributes of mathematicalproblems or expressions <strong>and</strong> to specify the class or classes to whichthey belong.b. Deduce: to relate a set of statements so that acceptance of the statements<strong>and</strong> their interrelationships dictates a particular conclusion.c. Estimate: to use available mathematical information to make a judgement ofm;a~ent or of a result of calculation.d. Generate Pattern: to put known or available mathematical data into a systematicarrangement.e. Hypothesize: to recognize or to generate conditional relationships betweenmathematical statements.f. Translate: to substitute for one mathematical form, an equivalent representation.g. Trial <strong>and</strong> Error: to apply knowledge to a mathematical problem in an unorganized'manner.h. Verify: to apply data to a hypothesis in testing its validity.. Ipp. 38-5'9J(References <strong>and</strong> Further ReadingsAkers, Betty.
