Acquisition of the Concept "Biodegradable" Through Written Instruction: Pretest and Age Effects.
Arganian, Mourad P.; And Others
The primary purpose of this study/experiment was to determine whether children in the middle elementary grades would be able to learn the concepts "biodegradable agent,""biodegradable material," and "biodegradable process" from a short written lesson. Secondary purposes were to examine the degree to which a pretest, grade level, and sex of the student influenced the amount learned. The three concepts were analyzed to determine their relevant and irrelevant attributes. Examples and nonexamples of each concept were also selected. On the basis of these analyses a 5 1/2 page lesson was written. Information given in the lesson for each concept included a definition in terms of the relevant attributes of the concept, and both examples and nonexamples of the concept. A 12-item testing instrument was also developed. The basic design was a Solomon Four-Group Design with pretest and lesson as factors. The design was replicated at two grade levels, fourth and sixth, and sex of the student was also included as a factor. Concluding statements indicate that both fourth- and sixth-grade students gained information about the concepts by studying a short written lesson and retained a significant amount of that information for a three-month period. The reading lesson and tests are included. (Author/BL)
