Fortunately there are strategies that teachers can use for giving students this kind of help in fact they constitute a major portion of this book, and are a major theme throughout the entire preservice teacher education programs. For now, let me just point briefly to two of them, saving a complete discussion for later. One strategy that teachers often find helpful is to organize the content to be learned as systematically as possible, because doing this allows the teacher to select and devise learning activities that are more effective. One of the most widely used frameworks for organizing content, for example, is a classification scheme proposed by the educator Benjamin Bloom, published with the somewhat imposing title of Taxonomy of Educational Objectives: Handbook #1: Cognitive Domain (Bloom, et al., 1956; Anderson & Krathwohl, 2001). Bloom's taxonomy, as it is usually called, describes six kinds of learning goals that teachers can in principle expect from students, ranging from simple recall of knowledge to complex evaluation of knowledge. (The levels are defined briefly in Table 2.8 with examples from Goldilocks and the Three Bears.)
Bloom's taxonomy makes useful distinctions among possible kinds of knowledge needed by students, and therefore potentially helps in selecting activities that truly target students' “zones of proximal development” in the sense meant by Vygotsky. A student who knows few terms for the species studied in biology unit (a problem at Bloom's knowledge and comprehension levels), for example, may initially need support at remembering and defining the terms before he or she can make useful comparisons among species (Bloom's analysis level). Pinpointing the most appropriate learning activities to accomplish this objective remains the job of the teacher-expert (that's you), but the learning itself has to be accomplished by the student. Put in more social constructivist terms, the teacher arranges a zone of proximal development that allows the student to compare species successfully, but the student still has to construct or appropriate the comparisons for him or herself.
Category or type of thinking |
Definition |
Example (with apologies to Goldilocks and her bear friends!) |
Knowledge |
Remembering or recalling facts, information, or procedures |
List three things Goldilocks did in the three bears' house. |
Comprehension |
Understanding facts, interpreting information |
Explain why Goldilocks liked the little bear's chair the best. |
Application |
Using concepts in new situations, solving particular problems |
Predict some of the things that Goldilocks might have used if she had entered your house. |
Analysis |
Distinguish parts of information, a concept, or a procedure |
Select the part of the story where Goldilocks seemed most comfortable. |
Synthesis |
Combining elements or parts into a new object, idea, or procedure |
Tell how the story would have been different if it had been about three fishes. |
Evaluation |
Assessing and judging the value or ideas, objects, or materials in a particular situation |
Decide whether Goldilocks was a bad girl, and justify your position. |
A second strategy may be coupled with the first. As students gain experience as students, they become able to think about how they themselves learn best, and you (as the teacher) can encourage such self-reflection as one of your goals for their learning. These changes allow you to transfer some of your responsibilities for arranging learning to the students themselves. For the biology student mentioned above, for example, you may be able not only to plan activities that support comparing species, but also to devise ways for the student to think about how he or she might learn the same information independently. The resulting self-assessment and self-direction of learning often goes by the name of metacognition -- an ability to think about and regulate one's own thinking (Israel, 2005). Metacognition can sometimes be difficult for students to achieve, but it is an important goal for social constructivist learning because it gradually frees learners from dependence on expert teachers to guide their learning. Reflective learners, you might say, become their own expert guides. Like with using Bloom's taxonomy, though, promoting metacognition and self-directed learning is important enough that I will come back to it later in more detail (especially in “Facilitating complex thinking”).
By assigning a more visible role to expert helpers and by implication also to teachers than does the psychological constructivism, social constructivism is seemingly more complete as a description of what teachers usually do in classrooms, and of what they usually hope students will experience there. As we will see in the next chapter, however, there are more uses to a theory than whether it describes the momentto - moment interactions between teacher and students. As I explain there, some theories can be helpful for planning instruction rather than for doing it. It turns out that this is the case for psychological constructivism, which offers important ideas about the appropriate sequencing of learning and development. This fact makes the psychological constructivism valuable in its own way, even though it (and a few other learning theories as well) seem to “omit” mentioning teachers, parents, or experts in detail. So do not make up your mind about the relative merits of different learning theories yet!
