March 10, 2021 Study Finds That People Don’t Understand Proportions A new study conducted by researchers at the University of Cambridge suggests that people have difficulty understanding proportions, especially when it comes to understanding how changes in one quantity can affect the proportions of other quantities. The researchers found that people’s understanding of proportions was generally poor, and that they often failed to take into account the magnitude of changes when assessing the relative proportions of two different quantities. The study also showed that people’s ability to assess proportions was significantly influenced by their level of mathematical knowledge, as well as their level of education. The study, which was published in the journal Psychological Science, involved a series of experiments in which participants were asked to compare two quantities and determine the magnitude of the difference in proportion between them. The researchers found that people were more likely to underestimate the magnitude of the difference between two quantities if the difference was small, and were more likely to overestimate the difference if the difference was large. The study also found that people’s understanding of proportions was significantly affected by their level of mathematical knowledge, as well as their level of education. The findings of this study suggest that people may need to be more aware of
Classical drawing teaches a step-by-step methodology for establishing proportions and value relationships early in the process of developing a drawing.Step 1: Straight-Line Block-InUsing all straight lines, I block in the large, basic shapes with soft, erasable, vibrating lines. I try to spend as much time as possible on this first step. Even though it looks rough and simple, I spent over an hour just to get to this level of development. It takes quite a lot of careful study to establish these b
Drawing by M. Joy Lemon, Sadie Valeri Atelier Instructor One of my main goals as a drawing teacher is to improve a student's ability to see and draw accurate shapes. If you can capture the specific proportions and tilt of a specific shape, you can draw anything. What I have found is: Measuring doesn't help. A student who is taught to over-rely on measuring will insist their drawing is "correct" even when everyone else can see glaring inaccuracies. More than measuring, an artist must develop a
