Do puzzles and games have a net positive impact on student learning?

Mr Patrick Vieira, Teacher of Maths at WHS, looks at how completing puzzles and games can impact student learning.

One day, while travelling to school as a 12-year-old, I saw somebody solving a Rubik’s cube. This person would scramble the cube and solve it very quickly. He would do this repeatedly, and maybe it was just in my head, but he seemed to get quicker with every solve. Seeing a demonstration of that kind was nothing short of captivating to me at the time. It stayed with me throughout the day and when I got home, I told my mother about it and asked her to buy one for me. Neither of us knew what it was called but we took the trip to Hamleys with the hope that they would know. We were in luck! My mother paid for the Original Rubik’s Cube and I took it home excited to begin trying to solve it.

As does everything after a while, excitement quickly faded. The puzzle was difficult and did not come with any instructions. I had managed to solve one face by what seemed like sheer luck (blue, my favourite colour), but when I tried solving another face, my hard work became undone. It was so frustrating that I left it on the mantelpiece where it collected dust for years. Reflecting now, that must be how some of my students feel now when they are given a problem that seems too hard to solve at first.

A Rubik’s Cube (Wikipedia)

Fast forward to 2019 when I first joined Wimbledon High School, where I had the opportunity to join the Rubik’s Cube club as a staff member. Of course, if I needed to help students solve the Rubik’s Cube, I needed to have a good understanding of it myself. This time, I was provided with a set of instructions and I got to work. Solve the white cross, then complete the white face. Finish off the second layer and then begin the top… I repeated the algorithms for each of these over and over again, and eventually I solved my first Rubik’s Cube.

But for me, that was not the part that excited me. As I repeated the moves for each step in isolation, I began to see why these algorithms worked. Every move had a purpose, setting the cube up so that on that final turn, everything comes together. It was as if I were almost tapping into The Matrix of the puzzle and I could feel my perception of 3D space improving with every turn. It was then that it hit me. This could be an amazing educational tool… but has it been researched?

Research related to the Rubik’s Cube is very limited but there are many pieces of anecdotal evidence to suggest that there are huge benefits to learning how to solve the cube. The two which stood out to me were grit and creativity.


Grit is one of the most mysterious personal traits discussed in education. It is widely regarded as the trait most indicative of whether someone will succeed at a task, no matter if it is in business, in the army, or in school.[1] However, it is difficult to nurture. When we complete a task which requires perseverance, the hormone dopamine gets released in our brain. This is the automatic response of the body which reinforces positive behaviours. The more tasks we complete using grit as our fuel, the more we are comfortable and happy being “grittier” – we create a habit of perseverance.[2]

Solving the Rubik’s cube is one way of helping us reinforce that positive trait of using grit. One Maths teacher writes in her blog that after giving her students an assignment to solve the Rubik’s Cube, they showed increased levels of grit.[3] However, just as Carol Dweck writes in her book Mindset: The New Psychology of Success, as educators, we need to still be encouraging our students to persevere and reward their effort rather than their achievement.[4] These will bring about the best results in development of grit.


“Creativity?!” I hear you wonder. “How can you be creative when all you are doing is repeating algorithms?”

I had an interesting experience as I was improving my knowledge on the Rubik’s Cube. After learning the algorithms for the beginner’s method of solving and was able to do it well, I turned to an intermediate stage called the ‘CFOP’ method. There were slightly more algorithms to memorise, but I found my creativity bloom in the process of learning them.

From a fully solved cube, I picked one algorithm and applied it to the cube. Of course, this would mess it up completely. However, just for the fun of it, I kept applying the same algorithm and eventually I got back to a fully solved cube. I wondered why and I tried to see if I could do the same with the other algorithms. It turns out that they do. It takes a different number of repetitions for each algorithm but eventually I end up at a fully solved cube. Just for the fun of it, I also tried to combine algorithms or even reverse them. These made me see different patterns and other ways of solving it. I wasn’t really doing much with the cube but still, I thought to myself, “this is pretty fun.”

Where next?

So pick up your cube. Don’t just leave it on the mantelpiece like I did for years. There is a great opportunity to be had whether you are a teacher or a student. Returning to my opening point, do puzzles really have a positive effect on learning? Nobody really knows yet. But if it helps you develop perseverance and foster your creativity, I think it’s worth a shot to find out for yourself.

How do you create a whole school academic timetable?

Mr Bob Haythorne, Director of Academic Administration and Data at WHS, looks at the processes involved to craft a whole school academic timetable.


“I don’t know how you do it!”

“I don’t know why I do it!”

If I had £1 for every time I’ve had that exchange about timetabling over the years, I think I’d have been able to retire a few years ago.  If we add the other old chestnuts – “Why don’t you just reuse the same timetable every year?” and “Can’t you just get a computer to do it all?”– I think I’d have been able to retire before I’d even started!  I’ve been asked to write this WimTeach blog about timetabling, but I’m not sure I can do it justice within the allowed wordage:  there are textbooks on it and the standard training course is three days long, so this is just a potted summary of the process.

It actually starts a long time before September; in fact, we need to have a pretty good idea of what we’re offering to Year 12 over fifteen months earlier, when we hold our ‘Into the Sixth’ events.  This can be affected by the addition of new subjects, the removal of others and changes to the whole structure brought about by new government policies.  Straightaway, we can start to see why it’s not possible to copy the timetable over from one year to the next.  Add in staff moves, random variations in popularity of different optional subjects at GCSE and A-Level, and increases in the size of year groups and it soon becomes obvious why everyone retracts that question after a moment’s thought.  A senior school timetable is critically dependent on the GCSE and A-Level options, so a great deal of time is spent with individual girls in Years 9 and 11, mainly in the Autumn and early Spring Terms, to help them choose and to get the information from them that we need to make a start.

With options in by February Half Term, the fun begins!  The first task is to analyse the numbers to see what the staffing implications are.  Will we have enough Mediæval Tapestry teachers?  Or can we really justify running Industrial Botany for just one girl?  We need to give our part-time teachers a term’s notice of variations in their hours and any recruitment ideally should be sorted before the Easter deadline for giving notice.  Whilst the Head and HR team are resolving those issues, we are crunching these options to fit them into option ‘blocks’ – groups of subjects where classes will be taught simultaneously.  (The number of option blocks is equal to the number of subjects the girls are allowed to opt for).  There is software to help with this, although my experience is that if you ask the program to create a scheme from the raw information, it will give a ridiculous answer, if it can give one at all.  (We don’t want all three Mediæval Tapestry groups in one block if there are only two teachers and only one specialist classroom, for instance;  really we want them spread across three different blocks).  I find that manually allocating about half the groups into blocks based on common sense and experience and letting the software solve the rest works best.  It will then allocate girls to groups and you can see whether some groups are too big or too small, and you can experiment with moving them around until you get a solution you like.  Whether it will timetable is still another matter!

‘Blocking’ is the first stage of actual timetabling and can be a major task in its own right.  This is where we take the 70 periods of our timetable and draw up a table of what could be going on at the same time.  At this stage, its just 70 periods, labelled 1 to 70 – there is no thought about when each period will happen, except for certain fixed periods, like Y11 – 13 Enrichment, which has to be on Thursday afternoon because of its links with outside agencies.  Because Enrichment has so many small groups, it places a strain on staffing, so we have usually scheduled the largest Year group in Years 7 – 10 to have PE at this time.

How the Year 12 and Year 13 option blocks mesh together is critical.  We draw up a table that might look like this:

(In practice, I would show all the actual subjects in each block – usually between 8 and 12 different groups – so that I can see the clashes.)

The ‘No’s are because, say, the planned scheme for Year 12 block A contains three subjects where we only have one teacher, or one necessary specialist room, and these three subjects happen to spread across three different Year 13 (i.e. current Year 12) blocks – W, X and Y.  Something similar will be the case for 12C and 13X clashing, and for 12D and 13W clashing.  In this example, we see that all 12A lessons will have to be timetabled simultaneously with all 13V lessons.  The ‘?’ for 12D and 13Y might mean that it probably could work, but ideally we would keep them apart.  This means there are really only two solutions:


These will then determine the underlying structure of the entire timetable.  Making the decision about which one to go with is nerve-wracking – one might turn out weeks later to have been a poor choice!  These go into the Blocking table:


It gets a lot more fragmented after this.  Ideally, two Year 11 option blocks (7 periods each) would sit nicely under each Year 12/13 pairing, but it never works out that neatly.  For a start, there are only six option blocks, not eight, and Maths and English have more than 7 periods.  Again, there are restrictions caused by limited specialist rooms and/or teachers that determine which Year 11 blocks can and cannot go under which Year 12/13 pairings.  And after playing with this for a week or two, it’s time to insert Year 10, with the same issues, but with complications like Enrichment and PSHE being at the same time for Years 11 – 13, but there’s no Enrichment in Year 10 etc.  Bear in mind that the table above just shows one column for periods 1 to 14:  the reality is one column for each period …and a very wide table!  By the way, it’s probably around Easter by now.

Some timetablers would do all their blocking (down to Year 7) before attempting to schedule the lessons into actual periods on actual days, but either because I’m impatient or because we have so many restrictions on what can happen when, I tend to start scheduling now. (E.g. we have a large proportion of part-time staff, who – funnily enough – don’t think it’s really part-time, if you have to be available for all 70 periods, with a small number of lessons randomly scattered around!)  Now, at last, we turn to the timetabling software.  Again, you could try inputting all the information and hitting the ‘Autoschedule’ button, but when it’s finished trying (a few days later), it will either have produced garbage or – more likely – failed.  The problem is that there are too many arbitrary decisions that you would have to make when inputting all that information, so it’s better to build things up steadily, seeing what’s working and trying to keep as much flexibility as possible for later stages.  An example of an arbitrary decision would be to allocate all the teachers to the incoming Year 7 groups:  there is no point being specific about exactly who is going to teach English to which class, because any of the four Year 7 English teachers could take any group, without needing to worry about continuity from Year 6.  Doing so means creating an unnecessary restriction;  doing so across all subjects is just mad!

It starts with the fixed items:  Enrichment, Year 12/13 PE, PSHE, HoYs meeting, SMT meeting and lock these in place.  Then the Year 12/13 pairings, bearing in mind we want double periods etc..  Then Year 11.  Then realise this isn’t going to work, because of some staffing issue.  Rip out Years 11 – 13 and start again.  Repeat as necessary until there’s a satisfactory solution.  Add in Year 10.  Take out Year 10 and adjust the option scheme.  Retry Year 10….

This constant back and forth continues for a few weeks.  We now have some limited options in Year 9, so it’s a similar story and that takes about a week to sort out.  Finally, Years 8 and then 7, where there is much more flexibility, as one class can have Geography whilst another is studying English and another Art etc.. Even so, that’s another week and it’s May Half Term already  – or later!

So, why do I do this?  Because it’s a huge puzzle, but it’s a puzzle where the answer isn’t in the back of the book or in tomorrow’s edition;  it’s a puzzle where you have to keep changing the problem when it can’t be solved to one you think you might be able to solve… or might not, so you try turning it into yet another problem.

But when that final piece of the jigsaw slots into place, that multi-way swap that you think will do the trick does do the trick, that opportunity to move something that you thought you remembered turns out to be right, then I know why I do this!
