The Importance of Teaching Material to Suit Different Learning Styles
In my experience as a teacher (both in the classroom and as the primary educator of my children in our home-school), I am convinced that no two people learn the same way.
I love to learn by reading. My older son, diagnosed with dyslexia in the 2nd grade, learns best by listening. Well before he learned to read, he had an impressive vocabulary and an uncanny ability to recall facts that he’d learned as I read aloud to him. My younger son is a ball of kinetic energy. Unable to sit still in his younger years, I allowed him to jog in place as he did his lessons. Somehow, the act of moving actually helped him to concentrate on his school work.
There are four accepted types (or modalities) of learning: visual, auditory, kinesthetic, and tactile. Typically, students learn best when the material is taught in more than one way. Engaging multiple learning modalities is a great way to get the different parts of a student’s brain working together to make learning connections happen. Unfortunately, students are often expected to learn difficult material by merely reading a textbook. However, if the student is not a visual learner, they may struggle to understand.
Whenever I can, I provide students opportunities for hands-on learning. Making models of cells or atoms, using candy to demonstrate electron configurations, or playing bingo to practice using a codon table—with a little imagination, you can find a way to make learning fun outside of a textbook.
PhET Interactive Simulations
Of course, hands-on experiments aren’t always convenient or practical. Additionally, there are certain topics for which finding ways to incorporate hands-on learning is more difficult.
Many websites are available which provide fun FREE virtual labs that can be done anytime, anywhere. Websites are available that allow students to perform virtual dissections, or virtually perform a gram stain procedure to identify unknown bacteria.
In my quest to find online resources for my students, I stumbled across a gem. It’s called PhET, and I love it!
The PhET Interactive Simulations project is run by the University of Colorado, Boulder. Founded by Nobel Laureate Carl Wieman, PhET simulations (often referred to as sims) provide research-based, game-like environments for students to learn math and science.
Currently, simulations are available for topics in biology, chemistry, physics, earth science, and math. Activities within each topic can be narrowed down by grade level from elementary school through college. Simulations for elementary school give students practice with topics including basic arithmetic, calculating area, constructing circuits, and learning about the states of matter. For students in middle school, PhET features activities to help students understand basic algebra, lasers, forces, and other topics. High school sims allow students to explore the properties of light, radioactivity, capacitors, and much more.
The best part: all of the simulations are FREE!
How I Use PhET in My Classes
Currently, I am teaching a chemistry class to a group of high school students in a local home-school cooperative. In a perfect world, I’d have several days a week to teach these students. In actuality I only get one 50 minute class per week. PhET is an excellent resource to supplement our class time. Here are some examples of PhET simulations that I have encouraged my students to explore at home.
In the Build an Atom activity, students build the given atom by adding protons, neutrons, and electrons to the empty atom template. To complete this activity, students must practice retrieving information from the periodic table, understanding which numbers correspond to the element’s atomic number, atomic mass, and net charge. Additionally, students must recall where each of the subatomic particles belong.
In this example, students need to remember that an atomic number of 1 indicates that this hydrogen atom has one proton in the nucleus. The fact that the atomic mass is 1 signifies that it has no neutrons. The net charge of -1 indicates that the element has one more negatively-charged electron than positively-charged proton. Since the student already knows the atom has one proton, this means that the atom must have two electrons. Both electrons reside in the electron orbital closest to the nucleus.
The Build an Atom simulation can be found here:
Students can also practice balancing equations. In this example, they determine the balanced equation for the combustion of methane.
As students toggle up and down to add more of each type of molecule, a picture of each molecule is shown in the boxes. This enables the student to see a representation of how many of each type of element is present so they can easily determine what needs to happen in order for the equation to balance.
You can explore the Balancing Chemical Equations simulation here:
PhET has Something for Everyone
PhET has so many useful (and fun!) simulations on a wide range of topics and age levels. I can honestly say that I enjoyed exploring the site and all it has to offer.
