Why Minimal Guidance During Instruction Does Not Work: An Analysis of the Failure of Constructivist, Discovery, Problem-Base, Experiential and Inquiry-Based Teaching by Paul A. Kirschner, John Sweller, Richard E. Clark
This article was a great selection. The authors raised some important issues regarding guided and unguided learning. They suggest that unguided learning can be detrimental to learning. They argued against PBL, inquiry based teaching, and constructivism in favor of a guided approach. The authors argue for direct instructional guidance and define it as “providing information that fully explains the concepts and procedures that students are required to learn as well as learning strategy support that is compatible with human cognitive architecture. Learning, in turn, is defined as a change in long-term memory” (Kirschner, Sweller, Clark, 2006, p. 75).
The question that must be asked is there a time where unguided learning is an appropriate educational technique? If so, when?
Unguided Learning: When does it happen?
I would argue that unguided learning techniques can be effective in certain situations. We probably all engage in unguided learning everyday. When we go out search the Internet and click on a link that interests us or when we try a new food. Granted these are simple examples, but they are used to illustrate an experience has something to do with learning as we don't always a coach around to guide us towards the "correct" experience.
Novices vs. Experts
How many students here feel as though they are an expert in online education?
How many students feel that they are a novice in online education?
How many students feel that they are somewhere in between?

I am willing to anticipate that many of us feel that we consider ourselves somewhere in between novice and expert. In the article, the authors focused their research on the use of unguided instruction with novices who had inadequate knowledge for thinking and learning.
Constructivism and Novices
I agree with the authors that novices may not have the prerequisite knowledge necessary to operate in a constructivist environment.
However, before we can discuss constructivist activities and constructivism we should all have some background knowledge. Go to: http://en.wikipedia.org/wiki/Constructivism_%28learning_theory%29 for an overview of constructivism.
Here are some examples of constructivist learning environments:
http://www.coe.missouri.edu/~jonassen/courses/CLE/
Think about a student trying to construct his own experience about chemistry who starts randomly mixing chemicals together. The outcome may be that the student causes an explosion, receives third degree burns and learns an important lesson through failure.
Of course mixing chemicals together randomly is unsafe and perhaps in a chemistry class the teacher would choose not to implement unguided learning techniques, especially if the students were novices. However, the “advantage of guidance begins to recede only when learners have sufficiently high prior knowledge to provide ‘internal’ guidance” (Kirschner, Sweller, Clark, 2006, p. 75).
So the question to consider is what is the research on unguided instruction with students who are not novices? When should the use of unguided instruction be considered? Do you see a place for unguided instruction in your own work or research?

At first glance, these articles complement each other well -- a heutagogical approach strikes me as being necessarily a constructivist one. If you're guiding your own learning, you are making all the decisions and (hopefully) learning from them as you go. If we consider that learning with the guidance of an expert may be more effective than constructivist learning, than these two pieces form the basis of a lively debate.
But my brain is full, so I'm going to read them again.
I am sorry that I did not read this article first. It might have guided my answers a little more to AP's article. But I did describe a self directed approach by a doctor treating the patient. Sometimes self directed learning is needed if the "directed" approach doesn't fulfill the learners needs.
I think I will re-read both articles myself
I agree that a blended approach would appear to be the most effective -- the safest, too, allowing us to hedge our bets much as we do when it comes to reaching and engaging learners by providing multiple channels and redundant loci of control.
The article effectively lays out - and effectively defends - its position that minimal guidance, while attractive for a variety of reasons, is ineffective. I was impressed with the depth of scholarship in this article. I do think, however, that minimal guidance has its place.
By allowing the learner the ability to find his own way when appropriate (which is always a judgement call) and within parameters set by the instructor/manager/designer, we can gain internalization of the content and buy-in on the part of the learner, assess- and evalu- ability, and maintain sufficient metrics to justify the activity in a corporate-like environment. NYU's experience with online-only instruction and the higher success rate seen with a hybrid approach (like this one) is a good example of the value of applying some formal structure to a potentially free-form educational experience.
Everyone is so kind! I thought the authors were tilting at windmills. I agree that a blended aproach is best, and I rarely see anything else. Most people using inquiry learning methods use something like the FERA model (Focus, Explore, Reflect, Apply). There is definite guidance involved. Depending on the age of the students, their familiarity with the topic, and their familiarity with the scientific procedure- the variables and tasks are limited. Teachers slowly build the students' knowledge and their ability to work without guidance.
I checked out the Mayer article (2004) the one that is used to debunk all unguided instruction. What Mayer actually concludes is that pure unguided instruction works poorly, but minimully guided instruction, active learning, works quite well. That seems to be very different from what the proponents of direct instructional guidance.
Thanks for checking out that article, Marc! It's interesting to learn that Mayer sees value in minimally guided instruction, which the authors of this article would have us believe he doesn't.
After reading the article and everyone's comments, I've begun to wonder about the practical applications of these learning theories. How does one design "minimally guided" versus "unguided" instruction, and do so effectively? How does one effectively "blend" theories to come up with a working and cohesive whole?
Speaking from experience: Several years back, I taught in a well-known publically-funded ESL program whose director so firmly believed in discovery learning that grammar texts were banned from the classroom. This director claimed that if all our students walked around with an English-language paperback in their back pockets at all times (and read them, I assume), they would all acquire English just fine. Now, we were working with absolute beginners in many of our courses; in the time it would take them to "figure out" a simple grammar rule and how to apply it generally, they could have learned half a dozen such rules and gotten in a lot of practice using them. This hit-or-miss approach was tremendously frustating for both the teachers and the students. The upshot of the "no grammar book" rule? We teachers "snuck" grammar books into our classes, taught rules like fiends whenever we could and hid the books when we were observed.
It seems to me it's easier to operate at the ends of the spectrum -- either the highly-structured end of the fill-in-the-blanks grammar text or the totally unstructured end of the read-novels-till-you-learn-grammar approach -- but it's most challenging to effectively operate in the middle area. It seems that from a teaching perspective that's where the greatest amount of work for the instructor lies (those guided worksheets cited in the article may have been effective learning/teaching tools but they certainly took someone a lot of time and effort to come up with), which may be one reason why it's not the most popular approach.
Thoughts???
I have to admit - there is something to be said for information being retained in long term memory in order for it to be considered "learned." But in an environment rich with information, a self-directed learner can retain knowledge in long-term memory much more effectively, than in traditional models of teaching, such behaviorism or cognitivism.
