Just 15 minutes a day

Parent Jonathan Fague shares how 15 minutes a day has changed his outlook:

I have 4 kids 3yr, 12yr, 14yr & 17yr.  One thing I enjoy is helping and tutoring them in their school subjects.  However, I do not have a strong math foundation and as my kids has gotten older I found that I am no longer able to just pick up their text book and explain what they need to do. Many, many  times I’ve found that what I was trying to relay to my kids was completely wrong.  I want to increase my math knowledge because I enjoy being able to help my kids.  I decided to just try and spending 10-15 minutes a day on the Khan Academy site.  It’s now become something I enjoy doing as I wind down and I’m finding that 15 minutes just isn’t enough.  What I’d personally like to relay is just how valuable this is for parents like me that don’t have a strong math background but want to get better at it for our kids benefit. It’s not going to change my career but it’s helping me be a better parent and I really appreciate that.

Programming through Art and Math

Over the summer, Los Altos School District teacher Sheena Vaidyanathan shared the essay below with CSTA’s The Voice about using Khan Academy’s ever evolving and growing computer programming platform with her students.  She also presented at the CSTA conference on July 16, 2013. 

For more about Sheena’s classroom, check out this article with more details. 

Curriculum in Action
Programming through Art and Math
By Sheena Vaidyanathan


Teaching computer science (CS) through art engages students and showcases the creativity behind programming. Connecting programming to math makes CS relevant to the school curriculum and ensures support and funding.


I combined CS with math and art to create a CS course called CSTEM for the Los Altos School District in California. Because CSTEM is a required class, every one of the over 500 sixth graders learns to code as a medium for creating art.

This year, I used the JavaScript implementation of Processing with the Khan Academy IDE. We began with a ‘human computer’ exercise in which students acted out three lines of code to draw a house and then coded the process on the computer.

Students were surprised to see how the code on one side of the IDE translated into a design on the other. Students experimented with Processing functions to add windows, fences, chimneys, and other features to their houses. By the end of the first class, students had learned to use functions to create a variety of shapes. Important learning occurred around syntax, sequencing, and parameters.

Students at this age are just learning to graph coordinates. In the Khan Academy IDE, students can guess numbers for the parameters and then use the sliders to experiment. The program output is updated instantly. This form of playing with the x and y values makes the math exercise relevant and fun. In addition to coordinates, students explored other mathematical concepts, including functions, variables, and geometry. Once I had introduced iteration using the draw function, the students were able to create interactive art based on the mouse position variables.

Many students worked outside of class to create complex works of art through code. Using the cloud-based IDE made it easy for students to log in from home to continue working. To facilitate learning beyond the classroom and to manage a large number of classes, I made extensive use of Edmodo, a moderated online classroom, where I post messages and engage in discussions. Students used the environment to share their work, comment on other projects, and ask questions.

I asked the students what they would say to convince others to learn programming; their answers were inspiring.
• I would tell someone that coding is a type of art. There are no bounds to your creativity and you can create anything you want, it can be easy or hard.
• You should try coding! It’s really fun, but I’m not promising that it will be easy. It’s really useful and teaches patience.
• Coding uses all that I have learned in math and applies it to
the real world.

I have seen the value of connecting programming to both art and math; my students are enthusiastic about programming and my school administration is ready to expand the program. A recent, first-ever district coding competition attracted over 100 participants—and 58% were girls! CSTEM has convinced students in our district that CS can be challenging and fun. Required CS education at this age is both valuable and possible.

The Value of Failure

Article by Derek Oldfield, a math teacher at Blennerhassett Middle School in West Virginia. Check out his blog at http://derekoldfield.edublogs.org.  

Let your child fail.  That was my initial reaction to a recent message that showed up in my inbox.  We live in a “little league” age of celebrating success.  In t-ball, every player gets to bat.  In little league, every player gets a trophy.  I don’t disagree with instructional league rules by any means.  However, at what age does failure begin to have value? I was sitting in a department meeting recently when a district-level administrator asked me if I had analyzed test scores of last year’s students to determine if Khan Academy actually had any effect on those students’ test scores.  I replied honestly, and said that I had only checked on a handful of students’ scores.  But as I continued to ponder her request, I lost my appetite for looking up any more test results.  I realize that no matter what those test results may show, they don’t reveal one of the most important skills being taught in my class.  They might reveal which students learned how to apply the Pythagorean Theorem in a real-life situation, but what is not tested is perhaps the most important.  Tests of that sort do nothing to promote the value of failure. Upon reading that recent message from my inbox, I wanted to shout out “let your child fail.”  The shouting was not due to frustration, rather to be sure that my voice was heard by many.  And when I say fail, I mean fall.  Let them fall.  How can we learn to get back up if we never fall?  Or if someone else always picks us up.  Too often today, students are given every possible opportunity NOT to fail.  But why?  Why are we afraid of failure?  Putting students in frustrating and uncomfortable situations is a tricky part of my job.  I have to find that zone where students are frustrated enough to seek out a solution THEMSELVES.  I hear this a lot, “Well I’ll just get my mom to help me.”  There’s nothing wrong with phoning a friend or a mom.  My message to parents, though, is to let your child fail.  Sometimes teachers put students in a certain situation so they will fail.  Because until they fail, they’ll never seek out that solution themselves.  Tests don’t measure whether a student has developed the fortitude to seek out a solution himself, or whether they’ve developed persistence in problem solving.  Even if a student doesn’t arrive at the correct solution, the journey or the number of attempts is often what is more important.  I always try to make sure that I’ve directed my students to places and opportunities where they can develop, create, or find a solution.  But I try to stop there.  Too often are students lead, directed, and told which solution is correct.  We call it “spoon-feeding”.  And students know all about this.  They know all about it, because it hits them like a brick wall the first time a teacher or parent shrugs their shoulders and refuses to help them at the first sign of adversity.  I want my daughter to be a successful, hard-working citizen.  I know that won’t come without learning to fail, get back up, and seek out a solution.
The picture below is a graph of a student’s last 35 problems on adding/subtracting negative numbers.  You’ll find the number of problems completed at the bottom the bars.  The red bars indicate a wrong answer was inputted first, but eventually the student arrived at the correct answer.  You’ll also see that the student’s longest streak correct was 11.  This particular student has been struggling adding and subtracting negative numbers for quite a while, but has just recently shown some progress.  We’ve exhausted ourselves on learning strategies.  We’ve talked about spending money, owing money, number lines, football plays, temperature, etc.  The student has struggled to find a solution that works consistently enough to stick.  However, it appears the student is finally getting it.  This particular student has learned a lot about persistence in problem solving.  The student has sought out the answer him/herself and used multiple resources along the way.  Consider what this student learned throughout this journey, in addition to learning how to correctly add and subtract negative numbers.  All because she was allowed to fail.

First day in the lab

Article by Derek Oldfield, a math teacher at Blennerhassett Middle School in West Virginia. Check out his blog at http://derekoldfield.edublogs.org.  

Derek kindly gave us permission to reprint his original post in its entirety below. 

These pictures (below) are from one of our computer labs in the school.  My students typically spend 2 days a week in a computer lab as part of a blended learning strategy.  In addition to face to face time in my classroom, I have really enjoyed the time my students get to spend at a computer.  There are some things a computer does really efficiently and Khan Academy provides me with a tremendous amount of data that I can’t imagine teaching without.  Just from today, I can tell which students need extra time converting 1-digit repeating decimals to fractions and vice-versa.  By tomorrow, 90% of my students will have demonstrated they are ready to move on to the next skill.  Back in the classroom I will try to incorporate engaging activities that reinforce what we’ve learned, while building on the next skill or topic.  It’s difficult to share in pictures or words, but already today I saw students helping other students.  This isn’t something I ask them to do, they just do it.  The atmosphere we create inside the computer lab is unmatched.  I’ll try to share more about my students’ experience in math class.  Ask your students about their experience thus far and feel free to contact me with questions or feedback.
