Description
A. The Need
Here’s a story that will send a chill down your spine. When I was at university, we had to build electric
circuits in the lab. One warning our lab assistant had given us was to make sure the capacitor was
connected properly since it was a polarized device and would explode otherwise. My lab peer didn’t
take the matter seriously enough and plugged the capacitor inversely ‘to get a good laugh at what would
happen’. I can tell you we did everything but laugh when the capacitor blew up sending shrapnels
everywhere; and shrapnels I would call them because the capacitor was big enough to have the effect of
a small bullet. My friend, well, he got slashes all over his face, which could have resluted in the loss of
one eye or both.
The reason I am telling you this story is because there are times when students are completely oblivious
to the dangers they are exposed to in the electric, physics or chemistry lab. And the incident at the
university was not as serious as the one I had witnessed earlier in high school when a student in my
class was about to accidentally mix the wrong proportions of oxygen and hydrogen in order to get
water, an assignment our teacher had given us. I still remember the teacher literally jumping at my
friend and snatching the beaker away from him. After a while, the teacher made a tiny demonstration
with extremely small doses of oxygen and hydrogen that resulted in a loud ‘boum’, simply to show us
how close we had been to real danger.
After these two incidents, and another that I read somewhere about a student who got intoxicated by
smelling a toxic substance in the lab, I kept trying to figure out ways to keep students motivated in
experimenting in a safe environment. Thanks to the online experiences that I took in CEP 811, I can think
of an excellent way to use Online Simulations. And I quote: ” (These) are a web-based recreation of an
authentic experience.” What I have in mind is using online simulations to teach students lab
experiments that could endanger their lives when mishandled. I have no intention of substituting lab
experiments with online simulations. Rather, I would use online simulations to demonstrate to students
the consequences of underestimating the dangers of lab experiments. After they have built an
awareness of those risks, they could go back to experimenting safely in the lab.
Another reason I thought of online simulations is because teachers don’t always have access to the lab.
So an online simulation would be a nice way to prepare students for what’s awaiting them in the lab.

B. The Plan
With online simulations, students are safe. They watch experiments while the teacher explains the
process. Better, the teacher can show students mishandled experiments without exposing them to
danger. These online simulations could be real but unfortunate incidents that happened to students
experimenting in a lab, or they could be computer programmed. In either case, students will be learning
in a safe environment how to avoid deadly mistakes in the lab.
My plan only requires the necessary online simulation, which is by no means expensive (or at least that’s
what I will try to find out in this project). I will try to find online resources that contain simulations about
lab experiments. If I find none, then I will probably make my own simulations using guinea pigs:-) Come
to think of it, it wouldn’t be a bad idea. I could have experts volunteer to record harmful experiments for
the sake of drawing students’ attention to the effects of mishandled experiments.
C. Relevant Research
Relevant Sites
1. http://www.virtlab.com/index.aspx:That’s a nice site that invites students to join a virtual lab where
they can experiment safely with acids.
2. http://phet.colorado.edu/simulations/: This site provides an array of simulated experiments in
maths, Physics, Chemistry, electricity, etc.
3. http://phet.colorado.edu/get_phet/simlauncher.php: Great site for all sorts of experiments.
4. http://phet.colorado.edu/teacher_ideas/browse.php: Here, you can find a wealth of contributions
made by online simulation advocates.
5. http://www.kented.org.uk/ngfl/subjects/science/simulations.htm: A set of interesting simulations
that help students interact with material basically they can’t have hands-on experience with.
Relevant Reports
1. http://k12wiki.wikispaces.com/Simulated+Laboratory+Resources+for+K-12+science: This site
discusses Simulated Experiments vs. Hands-on Experiments.
2. http://www.stormingmedia.us/72/7260/A726044.html: A site that clearly justifies the need for and
benefits of online simulations.
3. http://www.kented.org.uk/ngfl/software/simulations/: Read the top section. It clearly shows why
online science simulations are necessary.
4. http://highered.blogspot.com/2009/02/alternatives-to-lecturing.html: This site discusses
alternatives to traditional lecturing and suggests vodcasts, but the last part highlights the benefits of
simulations.

D. Connection to the four common places
1. The Teacher
The teacher will have 2 roles: With the online simualation, he/she can provide straight forward
instruction by playing the simulation and explaining the experiment while highlighting the risks involved.
He/She can also play the role of the guide on the side and have students deduce the risks involved. As
for the real lab experiment, the teacher will have to be extremely vigilent as to how the students
conduct the experiment.
2. The Learner
The learners are none but students with a certain sense of maturity and knowledge of how to navigate
the web in order to play the online simulation.
3. The Subject Matter (Content)
The content could be related to physics, chemistry, electronics, or any other field that exposes students
to danger when working in the lab.
4. The Context
Depending on the subject matter at hand, the teacher will explain to the students the need for online
simulations and the implications behind them. The students wil be aware that these online simulations
will prepare them for real lab experiments.
Note: Although I am an English language teacher, I can always make use of these online science
simulations. I can ask students to watch a simulation and describe the risks involved, the way it’s
conducted, summarize its benefits, and much more.
Appropriateness: This project is not intended for funding because existing online simulations are
quasifree, and making online simulations necessitates a video camera and a couple of volunteers. This
project is basically for fellow educators, especially lab and workshop technicians and engineers. The
project aims to convince fellow teachers by:
1. Showing them the need for online simulations (safety, opportunity to learn from trial and error …)
2. Showing them how simple and affordable they are (free of charge, easily accessible, easy to make …)
3. Showing them the pedagogical impact on students (assuming responsibility, bigger audience …)

Evaluation
My TechQuest on Online Science Simulations turned out better than expected, at least in comparison
with the plan I had in mind when I first got started. I thought I was delving into a far-fetched subject, and
that there was no point in carrying on as I wouldn’t come across many people with safety issues with lab
experiments. I couldn’t have been further from reality. A couple of tips for those out there willing to
take on a similar quest:

1. NEVER UNDERESTIMATE THE POTENTIAL OF TECHNOLOGY. Used properly, it can take you places
nowhere thought of with traditional methods. Students can:
Go to places so far away that it would be realistically impossible to get there.
Manipulate items that would otherwise be dangerous for rookies in real life.
Experiment while making intentional mistakes with the purpose of learning more and faster.
2. ALWAYS INVOLVE STUDENTS. I wasn’t planning on filming my students in the lab; but when my
professor suggested I should, I gave it a try and bingo! My students’ enthusiasm brought about a
level of seriousness needed for other students to really grasp the message behind the simulation.
3. TAKE FEEDBACK SERIOUSLY. When people comment on your design, they’re usually honest about it,
or else why would they bother. Sometimes, people on the outside see things from a different
perspective, or at least have a different angle on things. There’s no harm in trying out others’
suggestions.
4. BELIEVE IN WHAT YOU DO. Yes, it does matter how you undertake your quest. Your state of mind can
have a dramatic effect on the final outcome. Your students would always sense your attitude.
If I were to redo the TechQuest, I would attempt the following:
1. Make a better vodcast of the simulation so both the picture and sound be clear.
2. Involve more students in the simulation vodcast.
3. Make a podcast/vodcast with the students’ feedback on the simulation.
4. Distribute a survey to the teachers for their opinion of and suggestions for bettering both the use
and making of online simulations. This would help me assess the success of my project. You can find
the survey at the baddress below:
Survey on Online Simulations
My next TechQuest would probably be on E-porfolios and their impact on education. I would have
students create their own portfolios (after initiating them of course) and ask them to prepare a list of all
the educational benefits E-portfolios bring along that they can think about. I will also have them suggest
the content of the E-portfolio and the rationale they used for their decision making. This way, they will
have personally contributed to a piece of work that concerns them more than anyone else. Maybe later
on, they can make a podcast or videocast and publish it at school for others to learn from.
