In spite of the fact that the results have often been inconsistent, inconclusive, and even controversial, a great deal of progress has been made in educational research. However, research that broadens the vision also reveals new questions remaining to be answered. As the search for the one best teaching method has given way to the search for the most suitable method for particular students or types of students, the numbers of questions have multiplied. Moving into the area of learner characteristics in the affective-social domain has opened up a vast new territory for exploration. The problems in need of answers continue to be more and more complex, but the fact that more questions have been envisioned expands the opportunities for encountering hidden answers and for developing subsequent solutions to current problems. In this sense, future researchers have a more solid and extensive base from which to originate their investigations than those of the past, and education has much to gain from the positive results.
