One thing we hear over and over again is how hard algebra is. It's true -- learning algebra can be quite challenging. But it's also important: every subsequent math subject (geometry, trigonometry, calculus, statistics, and so on) builds on the foundations of prior ones, starting at algebra.
With AlgebraX, we're trying to make it easier (and more fun!) to pick up algebra. So are we accomplishing this? Where should we be improving our lessons? (That's something we ask ourselves all our time, because our authoring platform is uniquely suited toward iteration and improvement.)
One way to measure the difficulty of different topics is to look at how many students completed review questions (the assessments in AlgebraX) vs. how many students attempted those questions. If a topic is hard to learn (and/or our lesson on that topic could use improvement), we'd expect to see fewer students complete the corresponding review. Now this differs from how advanced a topic might be. For example, factoring quadratic polynomials is pretty advanced stuff for Algebra I, but students zipped right through those review questions in the course.
Here's a bar graph showing the completion of all the reviews in AlgebraX. Each topic has its own bar, and the vertical axis shows the percentage of students who started a review who finished it (meaning they mastered the topic).
- Two equations, two unknowns (78.3% completion)
- Fractional exponents (82.0%)
- Two equations, with no solution (84.1%)
- Solving for intercepts (85.0%)
- Point-slope form (86.7%)
- Discriminants and roots (87.5%)
- The quadratic formula (87.9%)
- Solving multi-step equations (88.1%)
- Multi-variable equations (90.5%)
- Distributing roots (91.0%)
- Perpendicular slopes (91.3%)
- Calculating averages (91.4%)
And what's the "easiest" topic? You might think it's something early on in the course, but then you'd be wrong. It's simplifying expressions by combining like terms, a topic that 99.8% of students have mastered.
We're already underway improving the more challenging topics in the course, both by improving the lessons themselves, as well as by adding new hints to review questions. Our goal is to turn this entire chart green. Yes, algebra will still have advanced topics, but nothing will be too hard for students to conquer!
Sometimes in the hints, I am unable to see the markings on the screen.ReplyDelete

I just want to say Thank You to everyone who supported me through the years. My name is Manuel Franco, 24, New Berlin Wisconsin. My story of how I won the Powerball lottery of $768.4M is a bit of a tale. I have been playing Powerball tickets for 6 years now since I turned 18. I bought my first ticket on my 18 birthday. I was feeling very lucky that day because I had contacted Prof Ibrahim to help me with the winning Powerball numbers. I really had that great great feeling that I looked at the camera wanting to wink at it. I only did a tiny part of it and trusted him. He gave me the numbers after I played a couple other tickets along with it for $10. I checked my ticket after the winnings came online and saw the numbers were correct including the Power play. I screamed for about 10 minutes because it felt like a dream. I had won $768.4M. This happened in April, 2021. You can check my winning testimony with the lottery officials just with my name search. Thank you Prof Ibrahim. Well, his email firstname.lastname@example.org,Tel: +27785149508 /ReplyDelete
