Final answer:
Sternberg's triarchic theory of intelligence suggests different instructional styles can benefit students categorized as high in practical, creative, or analytical intelligence. However, the results of Sternberg and colleagues' study are not provided in the original question.
Step-by-step explanation:
Sternberg's triarchic theory of intelligence differentiates between three aspects of intelligence: practical, creative, and analytical intelligence. The 1999 study by Sternberg and colleagues aimed to explore the effectiveness of instruction tailored to these different intelligence types. Students were categorized as high in either practical, creative, or analytical intelligence and were then randomly assigned to a class that emphasized instruction matching one of the three intelligence types. Unfortunately, the original question does not provide the results of this study, but according to Sternberg's theory, one might hypothesize that students would benefit more from a teaching style that aligns with their dominant intelligence type. For instance, those high in practical intelligence might thrive in a learning environment that focuses more on hands-on, real-world applications of knowledge, whereas students high in analytical intelligence might perform better in traditional academic settings that emphasize evaluation and problem-solving.
