Welcome


My interest in the idea of sharing pedagogical purposes comes directly with the contact I have had with the Project for Enhancing Effective Learning at Monash University in Australia. Now each of these teachers were very active in establishing learning agendas with their classes. The impact they were having was inspiring. Each classroom tool can have a purpose beyond delivering content, and this needs to be shared.
I suppose the purpose of this website is collate, crystalise and open dialogues about how to increase this within classrooms. As the quote from Carl Bereiter illustrates this classroom methodology can empower our students.

The myth of the exercise book.


One of the more enduring myths of my teaching career is that student's exercise book have the ability to show ‘progress’: it is easy to assume that a student’s book might show increases in complexity in their understanding of the topic and that that progress will be age and ability appropriate. However, the un-evidenced claim that a book shows learning comes with no proviso or qualifications. I would wager that anything that appears to be quite so linear, that so neatly moves from one concept to the next probably shows only that the students have attended the lesson and has engaged in the elaborate Punch and Judy show with their teachers to perpetuate the myth that learning is visible. What may be more indicative of learning is the students completing tasks that have similar content, that show the students interacting with the ideas, applying the ideas, getting the ideas wrong and then getting them right, and then revisiting them later in the year/term or module and getting them wrong again, and then practising with them. This is what the research tells us is how learning happens. The purpose of a school exercise book is not to demonstrate learning: they are focused on the now: the moment they begin to interact and think, to practice with ideas and engage in a dialogue about what is being learned. Student work is there to support the working memory, as well being a crutch for long term memory. It is a formative document, not a summative one.

Summative assessments should be separate, so that learning over time can be ascertained to the best of our sketchy abilities. It is much more valuable for a teacher to know what has been learned once an opportunity to forget has occurred. This makes the managing of learning much more difficult as it becomes a long term venture, and is anything but wrapped up in the here and the now of daily classroom interaction. Our curriculum needs to be organised and designed with this in mind, and no one has the time to do this. Despite every school stating that learning is what they exist for, the vast majority of schools and inspection regimes are satisfied with proxies of learning performance during classwork, summative assessments being there solely to determine a grade. What a shame.

Looking at student performance in lessons is not necessarily a bad thing as it gives us assessment information that cannot be dismissed. It provides a view of students understanding taken as a snapshot, at a point, in the here and now of the classroom; it guides towards how we might help students develop their understanding. We do this in the hope that the incremental gains, the quanta add up to make the greater whole, but until we get a grip on what learning truly looks like we are very much flying in the dark.

Ask yourself how do I know that each student knows x, y and z? We can’t really answer this as our evidence base of grades and percentages, the memories of conversations we have and of tasks completed are imperfect. Too imperfect. The reality is that we need information about performance and also about learning: though divergent, they are not opposite, but are parts of a bigger whole. As Neils Bohrs points out, “The opposite of a fact is falsehood, but the opposite of one profound truth may very well be another profound truth." But we are kidding ourselves if we think that student books and subsequent teacher marking in any way provides the richness and multi faceted totality of feedback student learning really requires.

Marking is only part of the story therefore, albeit an important and time-consuming part. But if you were honest with yourself you would admit that not every task we ask students to complete are in any worthy of the 6 hours of Sunday evening needed to mark them. This does not mean that some tasks are worthless as springboards for feedback just they might be more suited to the interactive variety of feedback given during the process of learning in the lesson.

To qualify for a full-blown marking assault one of four overriding qualities in the work set need to be present. It must at least have one of the following:

  1. It is a summative assessment.
  2. The quality of the student work (prose, content, detail) matters and the work (and the learning) would benefit significantly from redrafting.
  3. There is significant content being applied in a new(ish) situation.
  4. The content is in the process of being built upon over time (such as a threshold concept).

Marking absolutely everything that is entered into exercise books is not a helpful strategy because of the complete impossibility of doing this. Schools making policies need to use what we know about learning and feedback to guide practice and not just set some high handed, un-evidenced dictate in stone.

What does Nuthall really say about multiple exposures?

I made this table in 2014, it is based upon a now unsearchable document, namely the now illusive
"Nuthall, G. A. (2001a). Manual: Procedures for identifying the information content of student classroom experiences and predicting student learning."
If anyone has one lying around I would love a copy.

What is it? Well, these are the codes (albeit slightly incomplete, and slightly compiled from other Nuthall research documents) used by Nuthall and his fellow researchers to analyse the interactions students had with a concept. Their purpose was to allow them to predict if learning would occur based upon the "kinds" of interaction.Astonishingly they could oredict if learning would occur to an accuracy of 88%. This is to an extent that it will certainly do for me!

These may be a researcher’s tool, but they certainly illuminate a teachers understanding of how learning takes place, and as such are worthy of a little thought by teachers. It is indeed these research tools that presented us with the multiple exposure rule that if a concept is engaged with three or four times, depending upon the concepts difficulty and the students, then it will be learned. But they might tell us even more.

The codes are categorised into two types: A full set of information that is required for a concept to be learned, here coloured green. Sensationally the other category is a partial set of information that includes important information about the concept being learned.   Here these are shaded blue, and you will see that these are of several different forms. 

Description
Full set of accessible information needed to learn a concept: picture, words.
The exact information that that students need to hear, read, see, discuss or use in an activity. Information that must be engaged with.

Students need the chance to identify and extract relevant information.

Any prior knowledge they express is very much part of this.

Partial set of information with some important parts about a concept.
As above, but just not the full information.

  • Chunked explanations.
  • Corrections to work.
  • Relevant prior knowledge that they express too.

Working out Information.
Information that can lead to an inference or deduction.

Implicit use of key terminology.

Concept use when teaching another concept.[??1] 
Background information

Such as:
  • definitions
  • analogies
  • examples
  • non-examples
  • personal experiences
  •  

Activities that lead to a full use/view of the information.

These activities are more than just reading, writing and talking about a concept.  

  • Science practical
  • Making a model

The information is clearly about the concept
Activities that lead to a partial use/view of the information.

These activities are more than reading, writing and talking, but in this case do not give the full information. This may be information that can be used to lead students to make inferences and deductions.



It must first be noted that students not gaining access to a full set of information is not the result of crap teaching. There are numerous valid, and beneficial reasons why we would not want to present everything all at once: complex ideas need breaking down, or we may be helping students think through the content via definitions, analogies,  examples and non-examples and so forth. This information provides students with useful background information so that they can work out the meaning of concepts through induction and deduction.

 The partial information works in different ways: sometimes it provides a context for the learning and potential sources of useful prior knowledge, and sometimes we give information that will allow students to work out what the concept is in a more direct way.

 Nuthall then pieced together through observation, and interviews when and how students interacted with or engaged with information about a concepts. This really is a marvel. As a teacher you rarely get to see where and when students actually interact with the ideas behind a concept, our classrooms are too busy, with too many students and too many ideas being learned (and forgotten) all at once. So this schematic view of it is certainly worth pondering the interactions our students take in a process of a lesson: When? Where?  How?  How many? First exposure? Second? Did they think? Did they infer? Did they copy? Of course this is impossible to know as much of the important interaction  hidden in the mind of the learner. 























Nuthall used the categorisations

  1. Full set of information FSI
  2. Partial set of information PSI
  3. Activity that leads to a full set of information ALF
  4. Activity that leads to a partial set of information ALP
  5. Back ground Information BI
  6. Working out Infromation WOI

Nuthall himself said “ Provided a student is able to piece together, in working memory, the equivalent of three complete definitions or descriptions of a concept, that new concept will be constructed as part of the students long term memory” From the table It suggest that four  Full sets of information (FSI) will do the job, as will three provided there is an additional set of partial information.

If there is less than two full sets of information then students will require a total of five interactions with partial information sets.

This makes it essential for teachers to be aware what a full set of information may look like. This is difficult to achieve for every fact and idea you want students to learn.  Ergo, I do not think this is a planning tool, but a key piece of pedagogical content knowledge that will help us plan better teaching sequences.
 This research primarily suggests some useful planning suggestions. So that for learning to take place, students must:
  • interact with a full explanation of concept at least once.
  • interact with the information on at least four separate occasions.
 and that:
  • the more often they interact with the full picture the better for their learning.
  • perhaps breaking down concepts is not always the best strategy as more exposures will be needed for learning to occur for each of the smaller parts and then for the big idea you intended to teach.
  • related information can be deduced, collated and learned from many pieces of information.
  • we have to remember that, no matter how much we manage knowledge, we are entirely reliant upon students engaging with it!
The importance of a full set of information is problematic for teachers as We instinctively strive to break down immense potential complexity into neat, bite-sized chunks appropriate for student consumption. Sadly, this well-intentioned process may not actually benefit student learning; as the most effective teaching activities are often linked to big questions or ideas. This is probably best defined by David Perkins who, in his book “Making Learning Whole”, labels the breaking down of learning into small chunks, rather tongue in cheekly,  as a disease, naming it ‘elementisis’. The problem with elemetisis is that students never get to join the elements back together after they have been broken down for them, so that they may see how the knowledge works as part of a whole.
