The most difficult problem is setting up learning experiences to try to make interesting a type of activity which has become boring or distasteful to the student.Such an activity does not become interesting through sheer repetition.It is necessary to use a new approach in order to shift interest.The new approach may involve using totally different materials or it may involve putting the learning experience in a totally new context which is enjoyable to the student.Perhaps these four illustrations are enough to suggest the way in which one can work out a list of characteristics relating to the learning experiences that can be used in connection with each major kind of objective.In curriculum planning this kind of analysis should be made for each type of behavioral objective.Such an analysis will help to clarify further the definitions of behavior and will help greatly in the selection of learning experiences.The fact that there are many learning experiences which can be used to attain a given objective and that the same experience can often be used to attain several objectives means that the process of planning learning experiences is not a mechanical method of setting down definitely prescribed experiences for each particular objective.Rather, the process is a more creative one; as the teacher considers the desired objectives and reflects upon the kinds of experiences that can occur to him or that he has heard others are using, he begins to form in his mind a series of possibilities of things that might be done, activities that might be carried on, materials that might be used.As these take shape, it would be well to write them down as possible learning experiences.As they are written down, they might be outlined in more detail to indicate what they would include.Such a tentative draft of certain learning experiences should then be checked carefully against the desired objectives to see first whether or not the proposed experiences give an opportunity for the student to carry on the kind of behavior implied by the objectives and also whether the experiences sample the kind of content implied by the objectives.Next, the proposed learning experiences can be checked by the criterion of effect.Will the experiences suggested likely be satisfying to the particular student for which they are planned?If they do not result in satisfying effects, they are not likely to bring about the results desired.Third, the proposed learning experiences can be checked in terms of readiness.Do they require actions that the students are not yet ready or able to perform?Do they run counter to certain prejudices or mind sets of the student?Finally, they can be checked for economy of operation.Does the experience provide for the attainment of several objectives or does it care for only one or two?Having checked the learning experiences by these general criteria, it may by well then to check them also against some of the more particular characteristics implied by the generalizations about characteristics of learning experiences required for different types of objective.If the tentative formulation of experiences meets these criteria satisfactorily, then it would appear to be a promising plan to develop.If some of the criteria are not well met, there may be the possibility of revision in order to make the experiences more effective.If the experiences are largely inadequate in terms of these criteria, then the tentative formulation should be dropped and others developed.In this way the process of selecting learning experiences provides opportunity for creative proposals which are then carefully checked in terms of appropriate criteria.As a result, there is opportunity both for artistry and for careful evaluation in advance of setting up the definite plans for the instructional program.
