| Research Abstract |
In our previous study, we categorized two types of decision-making exhibited by the students in choosing allowable range of density values in identifying a given element. Type I is a reference value dependent (characterized by a narrow allowable range), and Type II is a neighboring value dependent (characterized by a broad allowable range). In this study, we examined the influence of teaching methods on the students' identification of elements by density. The following results were obtained :
1.We prepared two kinds of teaching materials. One was a density list in which the elements were arranged in an increasing density value order. The other was a density list in which the elements were arranged in an alphabetical order. Results in this study showed that the Type I group of students exhibited the same allowable range of values with any of the teaching materials used. However, the Type II group of students exhibited narrower allowable range of values with the alphabetically arranged list of elements.
2.Students belonging to the Type II group were categorized into two groups. Group II. A consisted of students who acquired density values which were far from the reference values, while Group II. B consisted of students who acquired values closer to the reference values. The allowable ranges of density values exhibited by these two groups were compared before and after the experiment. Group II. A students exhibited wider allowable range of values after the experiment while Group II. B students exhibited narrower allowable range of values after the experiment.
