4-D-1 Wikis in Your Classroom

My post is about a wiki project that inspired me!

Throughout the last module I’ve done a lot of thinking about wikis, and how I could incorporate them into my classroom. As a result of researching (the textbook, and internet sources for our Group Wiki, which was on Wikipedia), I came up with a wiki project that would greatly benefit both my students and myself.

Everyday I am met by students who were absent from school the day(s) before and want to know what they have missed. Sometimes these students are absent one day, other times they are absent three days, and sometimes they are absent longer and the days they are out may be consecutive or absent. As the teacher, it is difficult to remember a specific day’s events (on the spot), especially when the day in question happens to be a few days away.

So, I thought a great wiki project for students would be to complete “scribe notes” where one student posts the events of each day onto a class wiki. Generally there are about 180 school days, and each year I have about 90 students in a particular class. That allows each student to complete two “scribe notes”. I think I will make each scribe note 50 points, so that two of them (100 points) would be close to the value of a test.

The end result will be a student created wiki that contains a compilation of the work and schedule for every day of class! When students are absent from class (no matter if they are absent a single day or a week), they can check the scribe notes for the events of each day.  This will save me a lot of sanity!

Here is what I would expect an example of the scribe notes might look like.

Today’s General Topic: Boyle’s Law

 

Assignments That Were Turned In At the Beginning of Class

  • “Behavior of Gases Worksheet” (this can be found on the Portal under “Behavior of Gases” section)

 Today’s Agenda

  • Turned in yesterday’s homework (see above)
  • Took the “Pressure Conversions Quiz” that was worth 15 points
  • Learned about “Boyle’s Law of Gases” (resources for this lesson can be found on the Portal, titled “Boyle’s Law of Gases)
  • Started homework, which was a worksheet titled “Boyle’s Law Worksheet”

 Summary of Today’s Lesson

  • Boyle’s Law is the first of five gas laws that were are going to study
  • Boyle’s Law deals with the relationship between the volume of a gas and its pressure
  • Volume is the amount of space a gas occupies
  • Pressure is defined as the force per unit area. In terms of gases, we talked about pressure being correlated with the number of times gas particles hit the sides of the container they are in (more collisions = higher pressure)
  • Boyle’s Law states that there is an inverse relationship between the volume of a gas and its pressure, when all other variables are held constant
  • If the volume of a container or piston is decreased, the pressure of the gas            will increase, because there will be more particle collisions
  • If the volume of a container or piston is increased, the pressure of the gas                         will decrease because there will be fewer particle collision
  • The formula for Boyle’s Law (used to calculated changes in pressure or volume) is P1V1 = P2V2

 Ticket to Exit With Explanation

  • The original volume of a piston is 4 liters and the original pressure of the gas is 100 kPa. What will the pressure be when the volume of the piston is decreased to 1 liter?

Concept

Bolye’s Law is a literal mathematical inverse. So if the volume is cut down by a quarter (1/4 of its original value, because 4 x ¼ = 1), the pressure will do the opposite of this function. The pressure will increase by 4 times (4/1) of its original value. The final pressure will be 4 x 100 kPa = 400 kPa.

 

Calculation

P1V1 = P2V2

(4 L)(100 kPa) = (1 L)P2

P2 = 400 kPa

  1. This Wiki will also leave you and the students with the entire course summarized for the year. It will be very easy for you to go back and see what worked well and what didn’t. we lost a lot of snow days this year and a wiki like this would mean every one could stay on top of things by reviewing assignments if the teacher posted some introductory materials in the event of an unexpected day off. Super study guide idea!
