CFOP Method Part 2.1

Well, unfortunately, there isn’t much to report this week.  I have been practicing the OLL and PLL algorithms and my time is getting faster.  What I am finding now is that I am overthinking my solves (again).  This used to happen when I was only using the Beginner method and I would overthink an algorithm and end up mixing up the whole solve.

Now that I have new algorithms under my belt, sort of, I have found myself overthinking again.  I know that I need to do OLL before PLL but if I get an unexpected case on the last layer, I get mixed up and sometimes mess up the whole solve.

On the plus side, with all the solving I am doing, I am getting more comfortable with the cube and when I mess up, I am usually able to go back and fix it without having to give up on the entire solve.  My solving average is under 1:30 now, even if I have to fix something.

The best thing that happened this week was that I FINALLY solved a cube faster than my brother.  I know that is really petty (we’re both in our 40s) but he is a super smart tech guy and has been solving cubes for a lot longer than I have.  I felt really good about getting a faster time than him when he came to visit this weekend!  I don’t think I’ll ever get to the point where I can beat my son though.  He has been practicing with me and is able to solve the cube consistently in 8-12 seconds.  I’m still trying to solve in under a minute.

So, progress is still being made… I will post a video next week to show some of the new algorithms I have been using.

There is nothing new under the sun

The idea of remixing is not new.  In the documentary  this week, Kirby Ferguson gives examples of remixing and sampling in music going back more than 50 years.  In fact, remixing, sampling and copying have been around for thousands of years. The book of Ecclesiastes (written almost 3000 years ago) states:

 “What has been will be again,
    what has been done will be done again;
    there is nothing new under the sun.” Ecclesiastes 1:9 (NIV)

As a teacher, I am constantly remixing and sampling work for students.  In education, we often call it differentiation.  It is actually more common for me to differentiate a previously created activity than to use it exactly as it was originally intended.  The other phrase that teachers often use to describe this behaviour is to say that we don’t need to reinvent the wheel.

Differentiation, sampling, remixing and copying are the “wellspring of all creativity” (Ferguson, 29:50).  If we think about how students learn, it usually follows Kirby’s Elements of Creativity (Part 3):

  1. Copy (in teacher speak, “I Do”)
  2. Transform (“We Do”)
  3. Combine (“You Do”)

As a simple example, when a student is learning how to print letters, they start by tracing the letters on the page.  The second step is to write the letters without the tracing lines.  This part is the longest stage as students need lots and lots of practice and they figure out what works for them.  Finally, students make the letters their own – how many times have we held up a piece of paper without a name on it and had the student recognize their work by their handwriting?  We all print the same letters but, over time, each one of us develops our own style and personality in our writing.

On a larger scale, when we are taking someone else’s work and remixing it, we do need to be aware of Copyright Laws and we can’t take credit for work that someone else has done.  I looked into the statement that Kirby made about the US being the only country with a Fair Use clause (55:30) because I was sure that Canada also had the same idea in Copyright Law and I found that in Canada, it is called Fair Dealing.  Section 29 of the Canadian Copyright Act states that “Fair dealing for the purpose of research, private study, education, parody or satire does not infringe copyright.”

CFOP Method Part 2: 4 Look Last Layer

In my last post, I discussed my understanding of the CFOP method to solve a 3×3 cube.  I actually found the video tutorials less helpful than expected.  So, my son and I were able to find some documents that I could print out and use to help me.

 

The first document I found was in a Reddit thread and it looked fairly simple until I tried it. I found it confusing and when I looked back at the thread, it seems that not only are there errors, the algorithms and images were stolen from another website.  So, that one wasn’t helpful.

 

 

 

The second pages I found were on a blog by a cuber named Badmephisto and I was really hoping these would be more helpful.  In fact, this website is the one that my son has been using to learn all 57 of the OLL algorithms.  I liked the layout of these pages and the fact that the algorithms were listed with names such as Sune, Car, and Chameleon.  I find it easier to memorize the algorithm if I have a visual representation or fun name to go with it!   By the way, I call Sune the “fish” algorithm.

 

 

Finally, my son sent me a document from  the CubeSkills page – made by Feliks Zemdegs himself!  For those of you (probably all of you) who have no idea who Feliks Zemdegs is, check out this YouTube video all about Feliks who is considered the Greatest Speedcuber of All Time!

I don’t know if it is because of my age or… well, it’s probably because of my age… I wanted to have these documents printed so I could make notes on them.  I practiced for a few days with each of the pages and found that the CubeSkills document was the easiest to follow.

With this “cheat sheet” I am now able to do the 2 look OLL and 2 look PLL together to finish a solve.  I have memorized a couple of the algorithms but I still rely on the page to complete solves.

The other thing I have been practicing this week is timed solves.  I am not ready to do the 2 look OLL and PLL in a timed solve yet because I know I won’t be able to use the paper in a competition.  In my practice sessions, I do a few solves with the new algorithms and then do a couple of solves using the Beginner method and time myself.  The reason I am switching back and forth is so that I don’t lose the muscle memory of the Beginner method while I learn the new method.

My goal for this week is to get to the point where I can use the 4 Look Last Layer algorithms for the most common cases without having to look at the paper.

Teaching Foundational Skills

I believe that as far as education is concerned, social media fits under the umbrella of citizenship education.  It is not enough anymore to teach students how to be ‘good citizens’ in the physical world, we have an obligation to help them learn how to be productive citizens in the digital world. The Digital Citizenship Education in Saskatchewan Schools document quotes Ohler in this way: 

 

The Saskatchewan Curriculum has many references to relationships, interactions and interdependence, as well as creation and exploration using multimedia tools as early as Kindergarten in both the Health and Social Studies curriculums.  We need to be teaching skills such as reading critically, protecting privacy (of yourself and others), how advertising and marketing work, how online algorithms work and the difference between fiction and reality.  All of these skills can be embedded in both Social Studies and Health curriculums.  

There are great resources to help educators navigate this space but I think many educators shy away from teaching these skills because they don’t understand the skills themselves.  Having access to well curated materials is a great starting point! 

Common Sense Education has hundreds of lesson plans and Professional Development for teachers.  Accounts for teachers is completely free!  This is a great place for educators to find self guided lessons about AI, ChatGPT, Digital Citizenship, Student privacy and more.  I believe that learning about these online activities will empower teachers to teach them to their students.

Canadian Centre for Child Protection has resources for parents, kids and teens regarding online safety as well as free printable PDFs for use at home or in the classroom.  The teen section “Need Help Now” is an important link for teens to know.  It is a website that explains the steps to take if an inappropriate picture of you has been posted online.  The website is also directly linked to cybertip.ca.  For younger students, I have used the Zoe and Molly online activities with students in Grade 3-5 as part of the Health Unit on Personal Safety.

Kids in The Know is a resource I have used every year!  There are lesson plans for students from Kindergarten – Grade 12.  This website is funded by the Canadian Centre for Child Protection.  The only downside to this resource is that you need to purchase the materials and they arrive in booklet format.  This makes it difficult to stay completely current as technology changes.  That being said, I really like the resource for Elementary students because the focus is on the deeper learning of personal safety, healthy relationships and assertiveness – skills that are easily applied to all online activities that students will encounter.

Finally, Media Smarts is a great resource for teachers.  Access to this resource is provided free of charge for all Saskatchewan teachers through the Ministry of Education.  There are lots of lesson plans for use in the classroom but my favourite aspect of this website is the Professional Development section.  There is a section called Media Literacy 101 and another called Digital Literacy 101.  These resources are provided in a way that they could be presented as a workshop for teachers or they can be completed as self directed PD.

If we are going to be successful at teaching students how to navigate in online spaces, we need to understand the world they are living in and we need to focus on the important concepts of  reading critically, protecting privacy (of yourself and others), how advertising and marketing work, how online algorithms work and the difference between fiction and reality. When students can master these foundational concepts, they will be more prepared to handle the online world!

CFOP Method Part 1: Two Look OLL

I am diving into the world of the CFOP method!  The most frustrating thing about learning new algorithms is that it always slows down your time at first but I keep reminding myself that this new method will improve my overall times.

This week I learned some background on the CFOP method.  I learned that every record in the Cubing world has been broken using this method!  That’s impressive!!  I also learned what CFOP means – Cross, First 2 layers, Orientation, Permutation… I also came to realize that this method is going to take multiple weeks to learn.

I used CubeHead‘s tutorial playlist which was recommended by my son to start learning this new method.  I watched the first video where he explains some of the reasons why the CFOP method is preferred by most Cubers.  I was able to skip the next video because I already know how to solve the white cross (look at me go!!).  The third video is titled “Intuitive F2L Tutorial” try to understand F2L.  First of all, there is nothing intuitive about F2L at my level of understanding!  The video didn’t make any sense at all and he was going through the steps so quickly!  So, my next step was to ask my in-house expert, my 17 year old son.  His advice was to learn F2L last and learn OLL and PLL first.

I have attempted to capture my learning to this point in the following series of videos:

First, I explain how I have learned to use Cube Notation to scramble a cube

Next, I show a solve on the cube that I have scrambled (not my best time, but in my defense, I was talking through the video)

Third, I explain my understanding of the CFOP method as I understand it at this point

And finally, I use my learning and a different tutorial video to complete the 2 Look OLL

Of the tutorial videos I have watched so far, I prefer JPerm’s tutorials because they show each step clearly and he includes the notation right in the videos.

I will spend the next 2 weeks working on OLL and, hopefully, PLL so that I will be able to incorporate them into my solves.

Teachers have a tendency to ruin stuff…

Here me out… I think that when it comes to education, teachers tend to ruin the fun in things for students.  I’m not saying that all teachers ruin all the fun in everything for all students but, often, teachers with good intentions end up having a lesson or unit backfire because they have made something that students genuinely enjoy backfire by turning it into work.

Back in 2011, iPads were all the rage.  I was the new Teacher Librarian at my school and I had heard about the benefits of using iPads in the classroom.  I was a strong supporter of technology in the classroom for the next few years.  I led my school through learning about apps, screen time, technology contracts, BYOD, using Pinterest, Twitter, Skype, Facebook, Instagram, blogs, vlogs, Google Classroom, SeeSaw, and more.  I was very vocal about the importance of integrating technology, thinking “Well, they are on it anyway, we should show them how to use it correctly.”

That feeling of accountability hasn’t changed.  I still believe that it is very important to teach students about responsible use of technology and how to leverage technology as a tool for learning rather than using it only as a very expensive time-sucking-never-ending stream of random videos and memes.

My concern is that, in our enthusiasm to connect with the interests of our students, we can inadvertently ruin the fun of an app or website.  This in turn makes students less eager to use the platform we are teaching with and they find something new, thus starting the cycle all over again.

As a Librarian, I have seen this many times with novel studies.  Teachers choose a novel that is trendy and think that by turning it into a novel study, the students will be engaged because they already have an interest in the novel.  This almost always backfires.  In my own experience, I have seen this happen with books such as Diary Of A Wimpy Kid, Hunger Games, Hatchet, City of Ember and more.   It breaks my heart when a student stops reading for enjoyment because of a bad experience with a novel study (I have many thoughts about this topic, but I will save those thoughts for another day).

r/memes - Enjoying books Students Teachers Enjoying books forcing them to over Students analyze books made with mematic

In recent years, I have seen the same phenomenon with technology.  Minecraft EDU is the most prominent example that I can recall.  For a few years, Minecraft was everywhere!  Kids couldn’t get enough of it!  Then, once Minecraft EDU was launched and teachers started using it in their classrooms, suddenly, students were not as interested.  This happened with Coding as well.  Students loved coding on Tynker, Scratch Jr. or Blockly but as soon as it became part of a class through code.org, students quickly lost interest.

Of course, I am not saying that integrating technology into the classroom doesn’t have its place. Most students can run circles around me when it comes to learning a new app or remixing content to show their understanding.  There are wonderful, exciting ways to authentically use technology to enhance learning.

I know that there are great opportunities out there and many teachers do really amazing things with technology – please share the amazing things you are doing in the comments!

The Language of Cubing – Week 2

This week I focused on learning how to read Cube Notation.  I have a fantastic app called CubeTime which scores my times and shows my average over time.  It also provides random scrambles to solve.

Providing a series of scrambles for me to solve has really helped to motivate me to learn the Cube Notation.  I am able to scramble a cube and then complete the solve and record my time all in the same app.

For the first few days, my times were slower than average, I think because I was focusing on the notation and I was less focused on the solve.  Then I noticed something happening!  I was starting to understand the cube a little bit better.  By scrambling my own cube, I was learning how the pieces relate to each other through the scramble.  This helped my solves because I was spending twice as much time handling the cube than I had before (my son would scramble my cube for me).

This is an example of a scramble.  At the top you can see the Cube Notation (L2 U F’ etc.), the centre of the screen is where I add my time after solving.  I use a regulation timer to keep track of my solves so I have plenty of practice before going to a competition.  The picture on the bottom left of the screen is what the cube should look like if I have scrambled it correctly.  The boxes on the bottom right of the screen show the most recent Average of 5 (AO5), Average of 12 (AO12), Average of 100 (AO100) and overall mean of all my solves.

These were my current stats as of Sunday, Feb 2.  I am really proud of myself!  In just one week using the app and focusing on not just the solve but also the scrambling, I have been able to reduce my overall Average of 5 by more than 5 seconds!  I also have a new Personal Best time of 1:00.920 which is 7 seconds faster than my best time at the last competition.

My son tells me that the next step to improving my speed is to learn the CFOP method – I don’t know what that is yet but I guess this will be my week to learn it!

Learning the Language of Cubing

When I learned how to solve a speedcube, my son taught me one algorithm at a time and I gave each algorithm a nickname to help me remember it.  Here are the algorithms and nicknames that I use in order to solve the cube:

Step 1: Daisy

Step 2: White cross

Step 3: “Righty” for first layer

Step 4: “Righty and Lefty” for second layer

Step 5: “Weird” for yellow cross

Step 6: “H” for top layer

Step 7: “Upside Down Righty” to finish the solve

This has served me well for months but I am realizing that if I want to move forward with this skill, it is going to take a deeper understanding of how the cube works.  I need to learn how to read Cubing Notation.

Cubing Notation is the shorthand way of explaining each algorithm.  For example,  the “Righty” algorithm looks like this: R  U  R’  U’ which stands for Right side clockwise, Upper level clockwise, Right side counter clockwise, Upper side counter clockwise.

My son has assured me that the only way to get faster and learn new algorithms is to take a step back and learn this notation in order to move forward.  He has recommended a few cubers that I can learn from.  J-Perm has a tutorial site with videos and visuals so I started there.  Another popular YouTuber who does tutorial videos is CubeHead (my son’s personal favourite YouTuber).  I have watched both of their videos and looked at the notation and, to me, it feels very much like learning a new language.  I have to take time with the notation, practice with the cube and repeat the steps over and over before it will really start to make sense.

So, this week, I haven’t learned any new algorithms but I feel that I am starting to understand the language of cubing!

The Positive Side of a Cell Phone Ban

I may have an unpopular opinion here but I support the cell phone ban, at least, in theory.  I don’t agree with how the Saskatchewan Government announced the ban in the middle of the summer without proper engagement with teachers, administrators, students or parents and I do believe that it was a political move rather than a true effort to improve education in our province.  That being said, as an Elementary teacher, I see definite benefits for the students in Elementary schools.

In the past decade, more and more students are coming to school disregulated, unable to focus, and not ready to learn.  The unfortunate reality is that too many students are spending a huge amount of their free time on screens and it is affecting their sleep, their emotional regulation skills and their interpersonal skills.  Removing cell phones during the school day is far from the solution for all these issues, but it is a small step we can take to help students learn how to focus on others, be present and communicate effectively.

As a personal example, my son is currently dating a girl who has difficulty communicating in person.  When she has an issue with him, he doesn’t know about it until after the date, when she texts him about it.  She says she has anxiety, and although that may be true, my concern is that she has not learned the interpersonal skills of face to face communication through her teenage years.

As younger and younger children get consumed by texting, SnapChat, WhatsApp and other digital forms of communication, I believe they are desperately in need of a safe place to practice face to face communication.  This is where the cell phone ban in schools is starting to be effective.  When students are not tethered to their phone, they are forced to interact in more meaningful ways with others.  I have noticed that there seem to be more disagreements and conflicts between students but I choose to look at that as a learning opportunity!  As teachers, we are seeing more of the conflict that, just last year, would have happened on phones and we would never be aware of.  Disagreements and conflicts mean that communication is happening and these are invaluable opportunities for teaching social skills to children.

There are definitely downsides to a full cell phone ban as we talked extensively about in class and I think that, over time, we will need to find a compromise which allows teachers to use cell phones as the tools they are meant to be.  For now, let’s focus on how a cell phone ban can be a positive experience – the chance to teach emotional and physical regulation and the opportunity for students to learn valuable communication skills.

Here are a few of the videos I watched this week:

Becoming a Speedcuber

Five years ago, I had no idea that there was an entire subculture of competitive speedcubers out there.  My son purchased a Rubik’s Cube brand cube and taught himself to solve it during the summer between Grade 6 and 7.  It seemed like a fun party trick and he was also really into magic at the time so it just became part of his act.  As he improved his skill on the cube, he discovered that he could compete against other people!  The short version of this story is that I started travelling with my son so he could participate in these Speedcubing Competitions through the World Cube Association.

Fast forward a few years and I decided to let my son teach me how to solve a 3×3 cube.  He gave me one of his cubes and we spent our Christmas holiday practicing until I was able to successfully solve the cube!  I was very proud of myself, even though my average solving time was over 2:00.  In the world of speedcubing, that’s practically an eternity!  For reference, my son’s average time is around 0:10.

I decided to enter my first competition and, as expected, finished dead last!  Later in the year, I entered a second competition and finished second last.  I had improved!  Take a look at my competition stats:

This year, I will enter my third competition which takes place on March 22.  My goal for this assignment is to use online tools including YouTube videos and tutorials, apps for my phone and blogs from cubers to learn new algorithms and tips to improve my times so I can consistently solve a cube in under one minute.

One of my driving forces to improve my solving time and understanding of the cube is my school’s Rubik’s Cube Club.  I have been encouraging students at my school to learn to solve a cube and since September, we have met one recess a week to help and encourage each other.  This is proving to be a great way to interact with students that I otherwise would not have connected with and it is nice to see the students helping each other and enjoying the small victories of completing a new step in the solving process!
