Minding the Knowledge Gap - 0 views

  • In the meantime, I've written a book, from which this article is drawn, about all that I've learned from my research. In my book, I focus on what I identify as seven myths, or widely held beliefs, that dominate our educational practice. I start with the myth that teaching facts prevents understanding, because this (along with my second myth, that teacher-led instruction is passive) is the foundation of all the other myths I discuss. These myths have a long pedigree and provide the theoretical justification for so much of what goes on in schools. Taken together, all seven myths actually damage the education of our pupils. But here, let's focus on facts and the role knowledge has in our understanding.
  • Why Is It a Myth? My aim here is not to criticize true conceptual understanding, genuine appreciation of significance, or higher-order skill development. All of these things are indeed the true aim of education. My argument is that facts and subject content are not opposed to such aims; instead, they are part of it. Rousseau, Dewey, and Freire were wrong to see facts as the enemy of understanding. All the scientific research of the last half-century proves them wrong. The modern bureaucrats and education experts who base policy and practice on their thinking are wrong too, and with less excuse, as they have been alive when evidence that refutes these ideas has been discovered. Rousseau was writing in the 18th century; Dewey at the turn of the 20th; Freire in the 1970s. Research from the second half of the 20th century tells us that their analyses of factual learning are based on fundamentally faulty premises.
  • If we want pupils to develop the skills of analysis and evaluation, they need to know things. Willingham puts it this way:23 Data from the last thirty years lead to a conclusion that is not scientifically challengeable: thinking well requires knowing facts, and that's true not just because you need something to think about. The very processes that teachers care about most—critical thinking processes such as reasoning and problem solving—are intimately intertwined with factual knowledge that is stored in long-term memory (not just found in the environment).

  • The main reason they do not work is because of a misguided, outdated, and pseudoscientific stigma against the teaching of knowledge. The evidence for the importance of knowledge is clear. We have a strong theoretical model that explains why knowledge is at the heart of cognition. We have strong empirical evidence about the success of curricula that teach knowledge. And we have strong empirical evidence about the success of pedagogy that promotes the effective transmission of knowledge. If we fail to teach knowledge, pupils fail to learn.
  • By neglecting to focus on knowledge accumulation, therefore, and assuming that you can just focus on developing conceptual understanding, today's common yet misguided educational practice ensures not only that pupils' knowledge will remain limited, but also that their conceptual understanding, notwithstanding all the apparent focus on it, will not develop either. By assuming that pupils can develop chronological awareness, write creatively, or think like a scientist without learning any facts, we are guaranteeing that they will not develop any of those skills. As Willingham and others have pointed out, knowledge builds to allow sophisticated higher-order responses. When the knowledge base is not in place, pupils struggle to develop understanding of a topic.
  • In a lot of the training material I read, these knowledge gaps were given very little attention. Generally, the word "knowledge" was used in a very pejorative way. The idea was that you were supposed to focus on skills like analysis, evaluation, synthesis, and so forth. Knowledge was the poor relation of these skills. Of course, I wanted my pupils to be able to analyze and evaluate, but it seemed to me that a pupil needed to know something to be able to analyze it. If a pupil doesn't know that the House of Lords isn't elected, how can you get him to have a debate or write an essay analyzing proposals for its reform? Likewise, if a pupil doesn't know what the three branches of government are in the United States, how can she understand debates in the papers about the Supreme Court striking down one of Congress's laws?

    From American Educator, AFT - A Union of Professionals Teaching facts is critical to developing higher order thinking skills. An excellent case is made and the origins of our disdain for teaching facts in the works of Rousseau, Dewey, Freire and others is examined.

    I think this article compliments some earlier discussions I saw on Bloom's Taxonomy in our class and also some of the discussions I saw on Common Core. I would be interested in what the K-12 folks think about this article.

Early Attrition among First Time eLearners: A Review of Factors that Contribute to Drop... - 1 views

  • Some have reported attrition from eLearning as high as 70 - 80% (Flood 2002, Forrester 2000, in Dagger & Wade, 2004). Parker (1999) argues that “With the growth of distance education has come the problem of exceedingly high attrition rates”. Citing Carter (1996), she suggests that eLearning student attrition in some institutions is exceeds 40%, while others (Frankola, 2001). Diaz (2002), put it at between 20 - 50%,  and Carr (2000), estimate it to be 10% - 20% higher than for traditional on-campus education.

  • Employed adults tend to complete eLearning in their personal time due to workload pressures in the workplace and/or Internet access issues at work
  • Cognitive Load Theory
  • states that learning is initially processed in working memory
  • Learning complex or technically demanding material requires building mental models or cognitive schemas about the subject being studied or the skill being developed over time
  • Learning new material or a skill, for which a schema in long term memory is undeveloped or non-existent, can cause working memory to quickly overload its limited capacity. This overloading can result in a learner becoming highly anxious and losing confidence, which in turn can lead to the learning process, in effect, freezing and the learner being unable to continue.  
  •  “Digital literacy involves more than the ability to use software or operate a digital device; it includes a large variety of complex cognitive, motor, sociological and emotional skills, which users need in order to function effectively in digital environments.”
  • It is this author’s experience in designing, developing and delivering several eLearning programmes to public sector employees in New Zealand, that a face to face workshop prior the start of the online distance course can make a significant difference to a first time eLearner’s perception and experience of eLearning. 
  • This type of pre-course face-to-face induction workshop can also be used to foster the group’s sense of itself, and to identify the individual participants and their backgrounds, along with their expectations and concerns. It is also helpful to have the course design, structure and philosophy explained and to discuss anxieties associated with beginning an online course.

  • embrace a model based on a self-directed and motivated learner
  • undertake the learning tasks involved in interacting with peers via synchronous and asynchronous Computer Mediated Communication
  • Successfully negotiating this early experience depends very much on the relevant skills, circumstances, motivations and personal attributes of the learner. It follows then, that paying particular attention to how an eLearning course is structured and introduced and the manner in which the learner is inducted can make a very important difference in a learner deciding whether or not to engage and persist or to drop out. 
  • actually apprising learners of the issues of cognitive overload and how it is commonly experienced would go some way towards inoculating learners against its more pernicious effects.
  • Supporting learners till they are over the initial “eLearning learning-curve hump”, may involve a seemingly high level of resource and effort on the part of the course facilitator and associated programme administration staff, but the payoff is that fewer learners will drop out at the early stage.
  • Actively supporting, encouraging, gently cajoling and following up on learners who seem to be struggling will help to keep wavering learners in the course.
  • In terms of the actual course design and the structure of the materials and learning activities, then it is a useful practice to aim to start slowly and build the course tempo over time.
  • The one area where something may be done to reduce attrition is in the early stages of an online course.
  • Cognitive overload is a likely contributor to high drop out rates, particularly where those withdrawing do so within the first few weeks of the start of a course.  Greater levels of persistence and completions may be achieved if learners are supported to anticipate, prepare for, recognise and recover from the cognitive burden they may experience as first time eLearners.

    Looks at why some students don't make it through online courses- many first time online students are unsure what to expect and are just overwhelmed by the whole experience.

    The experience of the first-time online learner is qualified. Suggestions for decreasing early attrition are suggested.
  •  
    Attrition among mature adult online learners is affected by sociological, psychological, technical and cognitive factors, critical features of which are the notions of cognitive load and locus of control.

Taxonomy of Learning Theories « E-Learning Provocateur - 0 views

  • In 1956, George Miller reported that the “span of immediate memory” is limited to the magical number 7±2 items. From this, he deduced that the amount of information that could be processed at any one time could be increased by “chunking” it.
  • In 1977, Richard Anderson extended the work of earlier theorists such as Frederic Bartlett and Jean Piaget. His Schema Theory of Learning maintains that within long-term memory (or more specifically, declarative memory), knowledge is arranged in a hierarchical network of constructs called “schemas”.
