Artifacts #2- Chemical reaction primer

Part 2 of the Chemical Reaction Artifact series. Part 1 describes what an artifact of learning is and why I use them.

I'm not someone who really enjoys being the center of attention. I don't enjoy talking for longer than 5-10 minutes a time during class and yet I found myself being the center of attention talking much more than I would've liked during my classes. I had had enough. The dissonance between how I operate best and how I was actually operating led to the following project.

The idea

Students go through the unit on chemical reactions creating a different artifact for each of the three sections in the unit. The artifact must clearly communicate their understanding of the required content. They were free to choose whichever format they felt most comfortable using- most students gravitated towards a wiki-page, PowerPoint presentations, or some form of a newspaper/textbook document.

Documents given to students on day 1 of the project:


I decided early in the planning phases that I would avoid the perhaps more typical model of teaching the material traditionally (notes, lecture, review, etc.) up front, then having students work on a project as the assessment. I wanted the learning process to be wrapped up in the process of creation. However, I needed to support the students' learning. I couldn't just give them the rubric and tell them to get busy- they needed (and desired) some support. I decided to implement two support structures in order to help students while still keeping much of the onus of content learning on them.

Quick & Dirty Overviews. I did a brief (10 minutes max.) explanation of the required content broken down into three sections based upon how I broke down the content in the rubric. In addition to this, on the wiki-page for the project, I embedded an old presentation that I had used several years ago as notes for this section. I explicitly told students that these overviews covered only the bare-bones basics. It was their job to flesh these ideas out, provide examples, images, diagrams, and really show that they've mastered these ideas. These overviews served as a safety blanket for many students. The artifact was big and scary, and the overviews were just a touch of that style of teaching they'd grown used to over their schooling career.

Collaborative Groups. I placed students randomly into groups of three. At the conclusion of each day they worked on their artifacts, they met in their collaborative groups. Their requirements in the groups were to: (1) show each other what they have done of their artifacts so far, (2) help each other find resources for information/images/video, (3) check that everyone is citing their sources appropriately, (4) check that each others' information is correct.

Students were somewhat resistant to meeting in their collaborative groups. They wanted to keep working on their own artifacts, not waste time seeing what other people are doing. Students didn't do a great job of sharing useful links with each other and the thought of (in the future) getting students to use common tags in delicious or diigo crossed my mind. However, I'm unsure whether the time required to get students up to speed on social bookmarking would be worth the possible benefits. What was a major success was simply getting students to see what each other are doing. Getting to see how other people used images, organized their information, cited their sources, and so on seemed to be very helpful to many students.


It'd just be wrong to not have a couple labs when learning about chemical reactions. This section included two labs.

Exothermic and Endothermic Reactions. Students create two chemical reactions; one exothermic (adding yeast to hydrogen peroxide) and one endothermic (dissolving ammonium nitrate into water- it's not really a chemical reaction but it does get very cold).

Types of Chemical Reactions. Five reactions that demonstrate the five basic types of chemical reactions. Clicking the following links takes to you photos taken of the reactions as students performed them:

In the end

Students will upload their completed artifacts to the class wiki for all to see. At the time of this writing, students have completed their artifacts, but the upload process will happen this Monday (12/8). When they're all up I'll be sure to share.

My goal is to begin using the class wiki somewhat like a portfolio for student work. Each student will have a page on which they post their artifacts and other assignments completed throughout the year. I'm starting a little late on this for the current semester, but I hope to improve the practice in the future.

Authentic learning without technology? No way!

Walden PondThere' s a school in them there Woods. Matt Schlein raised the funds to purchase 260 acres of land and open the Walden Project- an innovative high school where class is held outdoors (except for when they have it in a motley-looking tent). The curriculum is based around Thoreau's writing, but by no means is no means limited. The NPR article notes:

"There's no need to go out in the hall or grab a new book. That's because everything is related, so class discussion about the recent primary vote in neighboring New Hampshire is just another aspect of the school's simple mission. Like Thoreau, students are supposed to be exploring their relationship to self, their relationship to culture and their relationship to the natural world."

This sounds quite similar to all the edu-talk about creating authentic learning environments through the use of global personal learning networks and other technological tools. The Walden Project doesn't utilize technology (though, as a joke, their tent has a satellite dish), but yet it sounds like authentic learning is taking place. One student is managing a corner of the forest. He's selectively culling some trees to determine if he can increase the biodiversity of plant life.

Personally, I'm drawn to the Walden Project model- I love the outdoors and would love to get to spend my days teaching in such an environment. I realize this isn't a feasible solution for the vast majority of schools and students. However, I do find it interesting that while many of us edu-bloggers are talking incessantly how technology can create authentic, interconnected learning, here's an example of a completely different solution that seems to basically have the same goals in mind. Perhaps technology is just a filler for those of us who don't have 260 acres of land to teach on...
