Having worked through the MyWorld program along with the literature background on it (Edelson, 2001; Edelson, Salierno, Matese, Pitts, & Sherin, 2002), I am not convinced this software is the right tool for the goals of Learning for Use program. For example, he Planetary Forecaster is an impressive document, which seems to do a good job working within the strategies of LfU, including motivating, constructing and refining knowledge (Edelson, 2001). However, the preliminary results from Edelson (2002) do not inspire a lot of confidence in the program achieving the desired academic outcomes. While students were able to discard misconceptions, they either picked up new misconceptions or were not entirely clear on the actual reasoning behind their new content knowledge.

In terms of earth science, the top student misconceptions are arguably based on seasons, moon phases, rock cycle and earthquakes (Bulunuz & Jarrett, 2010). From this list, I don’t see MyWorld as being an important part of the solution to addressing these misconceptions. Seasons and moon phases in particular have explanations that are rooted in a 3D spatial representation that MyWorld cannot represent. Furthermore, I don’t see how MyWorld plays a significant role in rock cycles and earthquakes, although I can see it as being part of an active learning process for providing support in the process of discovery.

The question then remains as to exactly what non-domain specific technologies are available that can support the LfU cycle. For this, I would look towards WISE. It’s structure and tools can definitely follow the cycle of motivation, construction and refinement, and appropriate java simulations can be inserted or used to help deal with topics that require a 3D spatial environment, such as seasons and moon phases. MyWorld could possibly be added to WISE in some fashion as a useful tool, but its focus as a primary technology used in the design of inquiry project is limited.

The issue of clicker technology in education came up a few times in our ETEC 533 discussions. I think there are some misunderstandings around using clickers, as it seems that many people see them as a teacher centered technology. While I suppose clickers could be used in this way, there are also some very well known techniques for using them in a student centered approach.

The methodology I am most familiar with came from Eric Mazur’s research and his Peer Instruction (Mazur, 1997). The basic idea is that the lecture is mostly removed from teaching, and classtime is used for dialogue, problem solving, and formative assessment. The clickers aid in this process as a conduit for the assessment and a means by which information is shared. One result from the peer instruction process is to remove the lecturer from being up at the front all class, and putting the onus on the students to help each other with the lecturer acting as a guide.

The following is a 5 minute video clip of Eric Mazur introducing his idea of peer instruction.

There are a whole host of issues surrounding technology in science education that can propogate from the peer instruction clicker use. One that is very interesting is that Mazur essentially started the process of “flipping the classroom” a decade before this idea became fasionable. Whereas people today might talk about Khan Academy and flipping the classroom, Mazur did the same thing ago with the exception that instead of watching a 10 minute video, he had his students read for 10 minutes.

For those of you that are interested in the classroom flip in science with videos, I urge you to watch this video by Derek Muller, aka Veritasium.

Here is a full 1hr 12min video from Eric Mazur. If you’re at all interested, I highly recommend it.
