Critical Thinking & ICTs – Part 2

In Part 1 I looked at three models which might be helpful in building a framework for understanding how ICTs and Thinking Skills offer affordances for enhancing students’ critical thinking abilities. I would like to start by looking at ways in which Bloom’s Taxonomy might be integrated with Semantic Wave Theory.

Bloom’s Taxonomy remains probably the best known framework for evaluating thinking in the classroom, but is of little practical use beyond a general sense that there needs to be more higher order thinking, or that a certain percentage of any examination questions need to call on higher order thinking. What it does not reflect is the interdependence of Lower & Higher Order Thinking, However, if we see thinking as a process over time, and not a discrete moment fixed in time, then it becomes clear that what is crucial to critical thinking is how ideas are linked, situated in context, grounded in evidence and logically connected.

If we look at Maton’s (2014) work on semantic waves, discussed more fully in Part 1, or how meaning is constructed and deconstructed in the classroom, we can see how critical thinking depends upon movements between abstraction and the concrete. Any claim of knowledge rests upon the logical coherence of the claim and upon its foundation in the evidentiary base. Maton’s (2014) work on semantic profiles suggests that in classroom talk, or student essays, it is the range between abstraction and the concrete that makes for rich, generative thinking. Talking in abstractions alone, or just in concrete terms does not lead to what we might recognise as critical thinking.

Two common classroom routines involve the teacher unpacking an idea for students, giving examples, metaphors, anecdotes which help them understand the concept. This represents a strengthening of semantic gravity, an unpacking of academic language, appealing to the ordinary everyday to help mediate the content and grow understanding. Learning, however, depends on the contrary movement, the student’s ability to take the raw stuff of experience and draw conclusions, analyse, synthesise and shape their thoughts into more abstract, academic formulations. This represents a lowering of semantic gravity and lies at the heart of what we expect those who display critical thinking to do.

I would argue that it is useful to think of Bloom’s taxonomy in terms of a full semantic profile which both strengthens and weakens semantic gravity as ideas are unpacked and repacked in the unique voice and understanding of the student. Higher Order Thinking (HOT) occurs, I would suggest, when the distance between abstraction and the concrete is bridged and where the amplitude of the wave is most significant. Lower Order Thinking (LOT), by contrast represents shallower crests and troughs. Remembering, Understanding and Applying, considered Lower Order Thinking skills involves less movement between abstraction and contextualisation than the Higher Order Skills of Analysing, Evaluating or Creating.

Let us be clear that both LOTS and HOTS are vital to all thinking. But it is useful to think of critical thinking as being characterised by fuller and more complete movement between the concrete and the abstract. Scientific Laws, such as Boyle’s Law, are formulated after repeated experimentation, measurement, observation and hypothesis formation. The Humanities likewise depend upon the formulation of abstract concepts, supported by rich contextual evidence. In the discipline of History, for example, a concept such as Hobsbawm’s Social Banditry draws from commonalities observed in a range of historical contexts, all of which provide support for the formulation of the concept and its ability to illuminate a narrative.

In this way I believe we can usefully conceive of Semantic Wave Profiles as descriptions of the direction of critical thinking, the strengthening or weakening of semantic gravity and Bloom’s Taxonomy as an indicator of the amplitude. The crucial takeaway for teachers is the need to provide opportunities for these movements of semantic gravity. Semantic profiles offer a way to visualise what is needed to create the conditions for better critical thinking and better learning.

In the next part of this article, I would like to suggest ways in which we can extend this framework to incorporate key insights from the Paul – Elder approach discussed in Part 1.

Critical Thinking & ICTs – Part 1

critical-thinking-cartoonThere is a narrative which says that ICTs offer unique affordances for critical thinking in the classroom. This argument sees the introduction of new technologies in the classroom as a prerequisite for a new emphasis on critical thinking. The 21st Century Skills Movement sees change itself as a rationale for the need for critical thinking, and technology as a central skill set for success in a changing world.

Now, this blog is dedicated to exploring how ICTs and Critical Thinking intersect, so I have rehearsed elements of this narrative many times. I do believe that ICTs have affordances which can be leveraged to achieve greater critical thinking, but the relationship is not simple or direct, and I have been around long enough to remember when teachers sought to foster critical thinking quite independently of digital technologies. As one who considers himself a champion of ICTs and Critical Thinking I believe it is important to have a theoretical framework for understanding the relationship between critical thinking and technology adoption which helps us to understand better how we can use technology to build better critical thinking.

Thinking around what critical thinking means is often somewhat woolly. For some students it appears to come naturally. Their arguments are well structured, well supported, with greater nuance and generative power. Other students struggle to present or analyze ideas effectively, and teachers are often unsure exactly what to do to help improve thinking. What exactly does effective thinking look like anyway?

Many teachers are using particular thinking strategies to foster critical thinking. Tools such as De Bono’s Thinking Hats, David Hyerle’s Thinking Maps, Harvard’s Visible Thinking or Tony Ryan’s Thinker’s Keys are designed to provide particular pathways to better thinking. These strategies represent pedagogies claiming to offer affordances for critical thinking in much the same way as claims are made that ICTs afford critical thinking. The claims for these strategies rest on the affordances of specific thought processes. For example the Thinking Maps offer scaffolding for promoting defining, describing, comparing and contrasting, classifying, sequencing, analyzing cause and effect, identifying part/whole relationships and seeing analogies. The Thinking Hats are said to maximise and organize thoughts and ideas by deploying parallel thinking techniques. The Visible Thinking routines represent attempts to increase metacognitive awareness, for example to draw on previous knowledge, explore diverse perspectives or deploy active reasoning or explanation. These cognitive strategies represent something of a toolbox. Much as a DIY handyman reaches for a specific tool to tighten a bolt or screw, remove a nail or fill a hole, particular cognitive tools can be used for different cognitive purposes. The teacher’s job becomes that of modelling and scaffolding student’s thinking, helping students recognise which tools are appropriate for what purpose and how to use them effectively to improve their thinking so that increasingly students are able to use these tools appropriately without prompting.

This way of looking at critical thinking is not the only way to conceive of it, but it is a useful metaphor for teachers and offers a focused approach which teachers can apply in their classrooms. The question is, is there a similar way we can think about how ICTs may be used as tools for cognitive education?

blooms_digital_taxonomySimilar approaches have been tried. For example Bloom’s Digital Taxonomy represents an attempt to map digital tools to Lower Order and Higher Order Thinking Skills. So, for example podcasting is seen as a Higher Order Thinking Skill of Creating, while Social Bookmarking is seen as a Lower Order Thinking Skill of Remembering. What this model lacks, however, is a nuanced understanding that tools in themselves do not mean much, it is how they are used, and for what purpose, that is important. One can use twitter, for example, at every level of Bloom’s taxonomy. One-to-one mapping of tools to a taxonomy of thinking regardless of purpose and use does not make much sense. Digital tools are not, therefore, the same as the cognitive tools described above. Any framework for digital cognitive tools needs to include their use and purpose.

For example, Google docs carry massive affordances for collaborative thinking. Students can collaborate on writing or problem solving tasks, using comment and joint editing to develop ideas collaboratively. But twitter can also be used in this way, and so can Skype, and many other tools. Google docs can also be used in ways which do not display collaborative thinking at all! Over the course of the last few decades teachers have identified uses of technology which can be used to aid cognitive processes such as collaborative thinking. It seems to me that any framework of cognitive digital tools needs to focus on the cognitive purpose rather than the technology. A useful approach would be to look at teaching practice and try to map cognitive digital tools to thinking processes. In order to do this, however, we need a much less woolly framework for understanding cognitive processes.

There are many different frameworks for critical thinking. I would like to detail just a few below, and then suggest a way forward.

Bloom’s Taxonomy

revised_taxonomyBloom’s (1956) taxonomy of the cognitive domain remains the standard framework for thinking about thinking in the classroom. It establishes six levels of cognitive processes which are seen as moving from simpler to more complex skills. The model has been revised by Anderson, Krathwohl, et al (2001), and both models are widely taught in pre-service teacher education and represent something of a lingua franca in the educational world. This is a considerable strength in that it is already the most commonly used framework by teachers concerned with cognitive education. However, I have to say that it is not a particularly generative model, and in my estimation is often used simply, and mechanistically to rationalise what is done in the classroom rather than to drive critical thinking. Because categories of cognition are not in reality discrete, the exercise of identifying levels is somewhat meaningless, and the pedagogical purpose of doing so unclear.

The model does not drill down to thinking routines themselves. Analysis, for example implies an ability to differentiate between premise and conclusion, what constitutes evidence, how to expose logical flaws, and so on. But the model tends to obscure this rather than highlight it. To my mind Bloom’s model ends up being a limiting factor in promoting critical thinking in the classroom. The taxonomy emerged as part of a movement to clearly define educational objectives and remove woolly thinking, but is in fact far more obscurational than the liberal tradition it replaced.

As we have seen with Bloom’s digital taxonomy, this woolliness both in the cognitive domain and how they map to digital tools renders the framework somewhat vague. What does it really mean when a teacher says, for example, that they are using blogs to enhance student capacity for creating?

The Paul – Elder Approach

pe-critical-thinking-modelThe Paul-Elder framework attempts to draw up a three-tiered model for Critical Thinking, defined as “the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action.” (Scriven & Paul, 2003). The model is based on the structures of thought, universal intellectual standards and intellectual traits exhibited by critical thinkers.

The strength of the model is that it does not focus on discrete thinking routines alone, but integrates the habits and dispositions of successful thinkers into the framework, and that it does manage to drill down to the elements of reasoning directly. Its major downside is its very complexity. For all its faults, Bloom’s taxonomy can be summarized in six words. the Paul-Elder model is more difficult for teachers to navigate. This limits its ability to be adopted more widely. Nevertheless, this complexity does hold out the promise for a more meaningful mapping of digital tools to thinking routines in the classroom. If a teacher were to say that they were using blogs to explore Fairness applied to Points of View to develop Intellectual Empathy, one can appreciate that the model is leading to a clearer notion of how digital tools can be used to sharpen critical thinking in the classroom.

Semantic Waves
10Another way of looking at the problem is to try to drill down to how meaning is constructed and deconstructed in the classroom. A new framework (Semantic Waves) for thinking about knowledge practices in the classroom, derived from the work of Basil Bernstein and Pierre Bourdieu allows us to bring powerful concepts to bear on semantic practices in the classroom. Maton (2014) has described how the concepts of semantic gravity and semantic density can be used to describe pedagogical practice in ways which allow us to think about the critical thinking implicated in classroom talk.

Semantic waves are descriptions over time of the relative semantic gravity or density of the ideas contained in classroom talk or student essays. Semantic Gravity refers to how concrete or how abstract an idea is, and is represented as SG+ a very concrete, grounded, contextualized idea, or SG- a very abstract, rarified concept, and of course all points in between. The word Revolution in History, for example, is an abstract idea, relatively free of particular contexts. A particular incident from the Russian Revolution, however, is more contextualized and concrete. One thing that teachers tend to do is to take abstract ideas (SG-) and help explain and contextualize those ideas by giving examples and instances (SG+), they help unpack concepts so that students can understand them better. They then help students take more concrete instances and everyday knowledge, and package in terms of the more academic language and understandings of the discipline they are studying, as shown in the diagram.

Semantic Density refers to how condensed an idea is. A symbol or metaphor conveys far denser meaning (SD+) than the everyday meanings of words (SD-). Poetry, for example is generally more dense than prose.

waving-not-drowning-7-638From the idea of the semantic wave, or how semantic gravity and density changes over time, Maton has described semantic profiles, or typical scenarios. Often discussion, or a student essay will remain generalised and abstract, never exploring examples, supporting evidence or anecdote to develop an idea or argument. This represents a high semantic flatline, as shown in the illustration. Often the discussion will remain at a concrete level, without any conclusions being drawn. This is a low semantic flatline. More usual in any kind of constructive meaning making is a much wider range and flow between abstraction and the concrete as arguments are made and supported by evidence. Seeing critical thinking in terms of creating semantic profiles opens up new ways of looking at both ICT usage in the classroom, something which I explored in my own research (Love, 2016), and how Thinking Strategies offer pedagogical affordances for meaning making – see the video below, which is an idea which needs to be explored.

I believe that the Semantic Wave framework offers a way of understanding how pedagogical approaches and technologies afford the construction and deconstruction of meaning in the classroom in detailed and powerful ways. It is, however, under-researched and must remain somewhat tentative at this stage. It represents both a pedagogy in its own right and a research framework. The ideas are somewhat abstract and may be off-putting to many teachers. To me as a teacher, the framework instantly made sense, but it is an idea that needs some explaining!

 

Putting it together

The three frameworks discussed all represent somewhat different ways of approaching critical thinking in the classroom, all with strengths and weaknesses. In many ways there needs to be synthesis of all three types of approaches to create a model which both explains and informs practice; allows for critical thinking learning objectives to be realised, and for tools and pedagogies to be integrated within any particular lesson.

In the next blog post I will try to unpack how I believe this might be achieved and to begin to suggest a tentative framework which meets these requirements.

Coding & The Liberal Arts

DSC00155Up until the early 20th Century Latin formed the basis of the Liberal Arts curriculum, not because everyone would be a Latin scholar, but because it was seen as something which taught one to think, because it was a rigorous discipline requiring accuracy and ability to master a logical system. It formed an excellent indicator of academic potential, and thus persisted in the educational system well beyond its usefulness as a lingua franca. In the 1900s it was largely replaced by History as a preparation for public life, politics and the civil service.

I would argue that the decline of History, and of Latin, has left a crucial void in the Liberal Arts. In a sense it has robbed the Liberal Arts of their importance in the overall scheme of things. When the main purpose of Education was to fuel the bureaucracy of the empire, the need was for individuals possessing the skills to administer vast tracts of foreign soil, far from home with a sense of duty and the ability to remain unflappable under enormous pressure. The study of Latin or History provided a sense of place and importance – it underlined the belief in the superiority of Western culture, and gave the colonial bureaucrat, trained at Harrow or Eton, a sense of their moral and cosmic worth.

The relativism and post-modernism of the last hundred years, along with the decline of the empire, has stripped away all sense of worth and purpose, and left only naked materialism. In Education, the Liberal Arts have been eaten away by the ascendency of Mathematics and Science. Now, I have nothing against the Sciences – they are absolutely vital in any education, but I believe that critical thinking needs a balance, a grounding in the Arts. I’ve just seen some research suggesting that good English teaching improves Mathematical ability. And I have a gut feeling that music is also vital. Drama too – hell, all the Arts are important, but I can’t help feeling that something is missing at the core of our curriculum: a humanistic study which is grounded in rigour and trains critical thinking.

Those of you who are still with me will be surprised now to hear that I am going to suggest that coding, computer programming fills this void. Is coding an Art? Surely it should be lumped with the Sciences. How can it fill that need for a rigorous study which simultaneously fuels a sense of moral worth and makes sense of the Universe? It is undoubtedly rigorous, and I would argue is an excellent training ground for rigorous thinking, so vital for critical thought. There is nothing quite as exacting or as unforgiving as a computer program. One comma out of place, a forgotten semi-colon can negate an entire endeavour. Programmers need to be able to conceive of the purpose and function of a program, design its outline and implement its details in ways which enhance user experience and maximise functionality. Game design, in particular, needs to engage on many levels at the interface between humans and machine. In a sense, like music, it combines creativity with mathematical precision.

I have a sense that the 21st Century is going to be all about how we manage our relationship with machines. The factories of the Industrial Age were one kind of machine, but the digital interfaces of the Information Age are quite another, and I have a feeling that the ability to hack one’s machines is what will define our ability to rise above mere consumerism. What the digital natives of the digital generation seem to lack is that ability to hack their machines. When I think back to what I did with my first computer, a ZX Spectrum, it involved almost only programming! There was precious little else you could do with it. Kids today experience computers almost entirely as platforms for products they download. Very little is done even to tweak these programs. Computing has become an act of consumption first and foremost.

We have a duty to teach kids to code so that people have the ability to act as agents of their own destiny in an increasingly complex digital world. Coding is therefore a humanistic project, perhaps the most vital expression of our humanity in a world where we are relying on our machines more and more.

What should replace History at the core of the Liberal Arts curriculum? Why, coding of course!

 

Integrating Thinking & IT

There is a common assumption that IT somehow leads to better thinking. The assumption behind this is that IT promotes more independent thinking, more self-directed learning and greater opportunity for promoting critical thinking. I am not saying that this is not the case, but I do think that it is only the case if we as teachers consciously and deliberately find ways of making it so.

Sans obstacles, gliding ahead with personalized learning.

GUEST COLUMN | by Maurice de Hond

CREDIT Steve Jobs School NetherlandsTwo points stood out at the recent ASU/GSV edtech summit in San Diego: there were three times more visitors than two years ago in Scottsdale, Ariz., and the number of new businesses and products in the field of edtech has now grown strong. The majority of those companies and products focus on personalizing education, responding to the level and possibilities of the pupil.

So long as your students are organized into age-based groups as has always been done, the best technology will deliver little return with respect to a personalized approach. It’s like trying to ice skate on grass.

I’ve been active in this field since 2012, like Max Ventilla of AltSchool. I got involved because I have a young child who started using an iPhone and iPad at a very early age. However, when…

Thinking Maps Software

thinking_mapsDavid Hyerle’s Thinking Maps are an effective set of tools supporting cognitive processes. Each map affords a particular process:

  • defining,
  • describing,
  • comparing & contrasting,
  • classifying,
  • identifying part/whole relationships,
  • sequencing,
  • analyzing cause and effect
  • and seeing analogies.

Thus they are different to Mind Maps, which map content, or generate ideas. The sharp focus on a particular cognitive process helps to stimulate very precise thinking around particular purposes. In the English classroom, for example, a Double Bubble Map can be used to compare and contrast different characters in a novel, while a Flow Map can be used to analyze the narrative structure of the text.

The Thinking Maps form an essential aspect to any teacher’s cognitive toolbox, and, like de Bono’s Thinking Hats, Visible Thinking Routines or Tony Ryan’s Thinker’s Keys can be used productively in many situations.

There is also a software download available which is easy to use and can be highly motivating for students, creating thinking maps with ease. These Thinking maps can be exported as image files for inclusion in projects or presentations. When you are researching a topic and typing up a report, the ability to compile a Thinking Map on the computer is invaluable.

 

Hack Your Life!

tdLearning to Code is all the rage right now, but how to implement a coding for all programme is not as easy as it sounds. There are a number of decisions which need to be taken. The first decision is around whether it will be merely open to all, or compulsory for all. At my school we expose all the students to a little bit of coding in their computer skills classes, in the form of some Scratch and some JavaScript. I also do a Game Design unit using Flash, with a little bit of Action Script. It works in that everyone can meet the requirements, but not all students embrace coding enthusiastically, so there might be a great deal to say for going the extra-curricular route, or maybe both.

I suspect that both is the right answer for most contexts. Everyone needs to be exposed to some coding, but I’m not convinced everyone can handle a full-on programme. the second decision is what programming language to use.

I started teaching some coding back in the late 1990s, with some Logo, and then quickly moved to JavaScript. The big advantage of JavaScript is that you do not need a compiler. All you need is a browser and a web editor. Currently I get my grade 9s to use JavaScript to create a quiz which will tell the user if they are right or wrong, and tally a score. When they create Flash games, I teach them to use AS3 to create drag and drops, and how to use tutorials to learn more skills. However, with many new interfaces for creating mobile apps appearing, my gut feeling is that this is the way to go, and I am probably going this route this year. MIT has a platform for creating apps, but there are so many popping up, I haven’t been able to research them all.

Here’s the introductory video for the MIT App platform to give you an idea of how it works.

The third decision is around how to build enthusiasm. Some students will enter into it with gusto and there is so much available online that they will be able to teach themselves. But getting the social aspect to work is vital to any programme having staying power. If you can meet face to face that is the best option, but in many schools the normal sporting and extra-curricular programme is so full, finding a mutually agreeable time is well-nigh impossible. I have tried running a virtual club, but the buy-in is limited. Special programmes which run for a limited period of time, such as a Hackathon or Hack Off may work better if you can find a niche in the calendar. I have been trying to shoe-horn some coding time into whole school programmes such as Cross-curricular tasks, or end of year programmes when teachers are marking exams and willing to sacrifice curriculum time, but for some reason staff meetings tend to resist the idea as soon as you mention coding, or even worse, hacking. For students the word hacking has a much more positive valency, however.

I honestly don’t know what the answer is, to all three questions, but I do sense that this year the zeitgeist is different. The idea that everyone should code is so out there, I think it may just take hold!

 

 

 

Flipping with MoveNote For Micro-Learning

movenoteIncreasingly teachers need to be able to rapidly post content online for students to review or revise. Video is usually fairly cross-compatible, but creating a video can be a daunting task for any teacher. MoveNote is now available as a Google add-on, and that simplifies things a great deal. If you have a web camera installed, creating video content for the flipped classroom becomes ludicrously easy.

Many teachers already have content on PowerPoint, or you can quickly put a PowerPoint together on the topic you want to present. You launch the app, or access the website, and enable the web camera. You can then add slides, or a single image. When you click record, you can talk into the web camera and advance slides in the app. When you’ve finished it saves as a video format, which you can download and store on your LMS.

The format of visual and talking head is an easy way of replicating the in-class “lecture”, and can be used to create very short chunks of byte-sized micro-learning. I really think that a limit of 60 seconds should be set. 60 seconds to explain an idea or concept. These micro-learning moments allow students to quickly access ideas they need when they need them. These quick videos can be downloaded as mp4s or viewed in a web browser, making them very versatile. If you don’t have a web camera, you can upload a video you have filmed separately.

The talking head can be replaced simply with audio, but I believe personalizing the videos really helps make them more accessible for students. The content can be … literally anything!
