This means we have resources that fit together like this:
An important point to bear in mind is that whilst a problem normally requires all aspects of a learner's problem solving skills to be brought to bear, it will probably only cover a limited area of content knowledge (possibly one key concept or several concepts which come together and enable connections to be made). In any single context it is often possible to place different emphases on different aspects of process skills, such as representing or communicating, for making particular teaching or assessment points. However, it is almost impossible and generally undesirable to try to isolate process skills when problem solving.
With this model in mind we now want to look at what progression in process looks like and therefore what we should look for when assessing learners' process skills.
There is progression in mathematical process/problem solving. This progression lies within the experiences of the processes themselves. Processes are not a simple set of six (or so) things to do in a particular order and once you have done them you can "do" processes. Process skills are complex beasts, in terms of breadth, depth and diversity:
So some time needs to be spent on a wide range of problems to ensure learners are given the opportunity to experience, and practise, the depth, breadth and diversity of process skills and in doing so they will become more competent problem solvers.
More detailed information on problem solving and mathematical thinking skills can be found in the research section of the NRICH website - articles including " Developing a framework for mathematical thinking" and " Mathematics Enrichment: what is it and who is it for?".
You might think of all I have said so far as sitting within the mathematics. However, much of what makes an effective mathematical problem solver goes beyond mathematical practice and into developing more general attitudes and ways of thinking that encourage confidence. These more generic skills will have value well beyond mathematics but are crucial in the development of effective mathematicians.
This is the area of progression that builds upwards from the content and process elements of the curriculum. In other words, we have a third dimension:
Effective learners develop through encouraging greater independence, reflection, resilience, participation and creativity, whilst offering contexts which are set in more complex and less familiar settings. As learners become more effective mathematicians, they also become more confident mathematicians and therefore better problem solvers. The strands of independence, reflection, resilience, participation, creativity, complexity and familiarity are ways of describing aspects of a more effective and confident mathematician. I cannot say whether confidence results in development along these strands or the development results in greater confidence. What is important is that confidence is seen as underpinning (or overarching) these ideas and is an important characteristic of an effective learner.
Explanations of the terms I have used can be found in the teachers' notes.
So, how does this link to NRICH problems?
Well, NRICH is full of resources which offer opportunities to practise and develop problem-solving (process) skills. The activities give scope for learners to work at a range of levels within those skills whilst encouraging them to move on in their thinking and confidence (the third dimension).
Using the problem Tricky Track I have tried to describe a progression in learner behaviour that might indicate development in the "third-dimension". In reality learners might vary considerably in each of the threads of development. For example, they may be very creative but not very resilient, or work independently - but only in very familiar settings or certain areas of mathematics. It is also the case that learners may score very highly in this dimension but be working at a low content-knowledge level. In other words, very young mathematicians will be very mathematical whilst working within content knowledge in line with their age.
Tricky Track
The following table gives examples of what might distinguish learners working at a low level in the "third-dimension" and those working at higher levels on the problem Tricky Track. This can inform us of learners' progression, the level at which they are working and their potential for moving on. The table also indicates some of the implications for teacher action that can influence learner behaviour.
Assessing Pupil Progress is about supporting learning. Its aim is to help teachers to find out more about their pupils' strengths and weaknesses, and help them plan for learning that takes into account learners' individual needs. Whilst there is a need to keep track of what a pupil can do and where they might go next, APP is not about ticking hundreds of boxes, levelling every piece of work, or doing additional assessment activities in addition to those you already undertake at school. It is about knowing what might come next on a learner's journey and offering opportunities for that learner to progress.
