Carol Dweck is one of the most famous learning theorists alive today. Though she has been studying mindsets for decades, she is perhaps best known for her (appropriately-titled) book, Mindset Her ideas have directly helped hundreds of thousands of readers learn and teach more effectively, and they have indirectly helped millions more by influencing the way we think about learning and intelligence... read more
No one likes to mess up, but going to great lengths to avoid errors - even when the consequences of making an error are benign - is unlikely to help you learn. In fact, in her review of the literature, Janet Metcalfe makes a compelling argument that making errors while learning - so long as you receive corrective feedback - results in better outcomes than making no errors at all. Her... read more
If 3r-s=10 then which of the following is equivalent to 27^r/3^s? The choices are 27^2, 9^4, 3^10
When planning to train for any kind of test preparation, most people assume that the best strategy is to gradually schedule more frequent tutoring as they get closer to the test date. This makes no sense. Think of the mind like a muscle. In this analogy, the first few weeks of training are slowly more strenuous, it's true. However, once you... read more
It's not controversial to aver that procrastination is bad. Most would agree without giving it a second thought. But what about procrastination is so harmful, and why do we procrastinate when we readily agree we shouldn't? When I talk about procrastination, I'm talking about delaying an important task despite knowing we will suffer as a result. Why would we do this? The problem seems... read more
It's fairly likely that you've heard someone talk about "mindfulness." It's less likely that you know exactly what mindfulness entails, and even less likely that you've heard of Ellen Langer, the "mother of mindfulness" in Western academia. In fact, even if you Googled mindfulness you'd find credit for its popularity in the West given to a man named Jon Kabat-Zinn. Langer's... read more
Getting Started I took the exam at Irvine Valley College. Unlike most schools, whose administrators post classroom assignments on a billboard, IVC showed up around 8:15, had students stand in the quad, and verbally had students split into separate groups like cattle. Then students ended up having to walk down a confusing pathway to a classroom, where we had to have our IDs checked... read more
Marshaling the cognitive resources and committing the amount of time required to earn good grades and high test scores takes effort. The rewards from these achievements are often delayed, while the rewards from having fun with your friends, playing video games, interacting on social media, watching tv, etc. are more immediate. What strategies can you use to help overcome this mismatch? In... read more
You might wonder what emotion has to do with learning, and why I am writing a blog about sleep and emotion. If you think about it, though, how you to react challenging situations - the emotions you feel, and the cognitions, physiology, and behaviors that accompany them - can have a profound impact on how you learn. Indeed, emotional reactivity can have a profound impact in multiple domains,... read more
We all know we do better when we're well-rested than when we're not. Modern sleep research has started to uncover exactly why that's the case. In terms of memory, there are at least two important reasons to make sure you're getting enough sleep. First, we better remember what we learned the day before. This is because sleep plays an essential role in the conversion of short-term memory... read more
Suppose that scores on the mathematical portion of the SAT college-entrance examination have a mean of 500 with a standard deviation of 100 and are normally distributed. A university that Brad wants...
During the school year, many of the students I work with have jam-packed schedules replete with extracurriculars, sports, and demanding classes. Adding test prep into the mix can complicate schedules even further. So why not take advantage of the time students have off during the summer to get ahead, so that when school resumes they won't have a heavy additional workload to worry about? There... read more
When I worked for Kaplan, they required all private tutoring lessons to be two hours. That surprised me because I thought of lessons as one-hour affairs. However, I soon discovered that we could get through a lot more in one two-hour lesson than we could in two one-hour lessons. Why? For starters, each lesson always starts with a few pleasantries and takes a couple of minutes to... read more
Sometimes I work with students who perform well during our lessons, but who struggle when it comes to actually taking the test. It turns out the reason for this might be genetic. When we experience stress, our prefrontal cortex is flooded with dopamine. Some of us are coded with a gene that slowly removes the dopamine, while others have a variant that rapidly removes... read more
The Economist recently published an article with some surprising research findings about stress. Contrary to popular belief, stress is not always bad, nor is it the amount of stress that matters. Rather, the key determinant of its impact on performance and health is largely psychological. In one study, researchers divided a set of GRE test takers into two groups. Saliva... read more
I can't speak for every tutor, but I know that if you work with me I have certain expectations of you in order to ensure that you will see the greatest possible improvement in your score. Luckily, they are really quite simple, and adhering to them makes a huge difference. I've attached a PDF version to summarize my Top 5 Test Prep Essentials that you can download, but I will review each of... read more
Ellen's Rules for Effective Time Management, Part 2 3. Know when it’s time to take breaks. Spending a good chunk of time on one subject is good; it helps you settle into a rhythm and lets your brain get into the correct frame of reference for the subject. But there exists a horizon beyond which no progress can or will be made. It’s the point at which your brain has become over-saturated... read more
Way back in 2010, one of my first blog post series on this site took the form of a five-part series on rules for effective time management. For the next few Ellen's Choices, I've decided to go back through these rules and apply them to the world of preparing for the SAT (or any standardized test). So let's begin with Part 1: All-Nighters Are Evil Ellen’s Rules for Effective... read more
A landscaper is designing a rectangular fountain with a 4-foot-wide path around it. The equation A = 4p + 64 will relate the area A, in square feet, of the path to the perimeter p, in feet, of...
