Alternative assessment (and the bribery of my students)

This week, I am not giving my Level 2 Physics class a topic test, even though they have finished all their learning about waves. Instead, I have given them an extended collaborative project. They all blinked when I said that, so I have taken to calling it "your jewellery project".

I don't really like topic tests. The project I have given them requires the students to work together to answer a range of questions that cover everything you'd expect a topic test to cover, but they get more time, can use their books and online resources, and can talk. I assigned the groups by getting them to line up in order of the wavelength of their favourite colour. I'm seeing a range of group styles in their different approaches.

First, some groups assign questions to different people and they work more or less independently on their own tasks. They seemed to assign the questions randomly. On the plus side, they are working pretty consistently. On the minus side, it does make them more likely to ask me for help instead of asking someone else in their group or looking up the answer. I guess they like having a reassuring someone to tell them things.

Other groups went through the entire question sheet and separated out particular questions. One group has one person who is the 'diagram specialist'. This person is doing all the ray diagrams, while another person is doing all the mathematical problems. This is quite efficient, and shows that they have some pretty clear ideas about delegating and division of labour. It means I can't be completely confident that all of them understand all of the topics, but I think that is a small price to pay.

Still other groups are all working on the same question at the same time, just different aspects of each one. These groups tend to be noisy, with lots of checking that they are all on the same page and all on track. They don't ask a lot of questions, but when I check in on them, they are clear about what they are doing and where they are going.

I think these types of group styles can rise organically in classes, like this one, where the majority of students know each other fairly well and are all confident about communicating their ideas. In other classes, particularly bigger ones where the students are younger and less self-directed, most groups default to the first type. I think this is a bit limiting in some scenarios, and I think I might set up some activities deliberately to tease out some other styles of group management.

I am pretty pleased with how seriously the Level 2 students are taking this project. Of course, when I handed it out and explained the parameters, they negotiated hard for a prize for the best team. We had some discussion about how 'best' should be defined, eventually agreeing that it would be a combination of group work skills and value added to answers since their last formative assessment. Naturally, the prize consists of food. On Wednesday, we will have a judging session and the winning team will nominate their choice of home baking. I think it's worth a few hours of my time.

I'm kind of embarrassed for them

I don't think my students quite understood what I meant when I said, "I will scan the pages that you make into a pdf and upload it to a sharing site so that you - and others - can access it." Personally, I think that is clear and unambiguous. My students did not quite get it, which, I think, explains why their pages look like something escaped from their pens and died on the paper. Well, perhaps that's a little harsh. Most of them are legible.

Optics Visual Dictionary

This was my first attempt at making an online visual dictionary with my Level 2 Physics class. They chose a word from a list I generated; in a perfect world, they would generate their own list from a pre-reading activity. Allowing the students to choose their own words worked well. Some students tried to pick a word they thought would be easy, but they turned out to be deceptively difficult. You should have seen the student who picked 'upright' as his word; it was a vexing task for him.

The biggest problem with this, I think, was that the students just didn't realise that when I said that I would upload it, that meant that I would be sharing it with other people. I trust that next time will look a lot more organised.

I love school *displays unseemly enthusiasm*

This morning has kicked off brilliantly - although I could do with more coffee. My Y10s did an interesting reading exercise about fossils, my Y13s estimated the rotational inertia of each other and used it to explain why we put our arms out when we balance, and my Y12s demonstrated Newton's First Law with an egg. Have some video evidence:


I'll stick this video on the school site too, so the students can access it. They had a lot of fun making it, even though there was a lot of "no, YOU do the voiceover" going on. We didn't have time to add a proper audio track, sadly. Nevermind, it's pretty good for their first ever attempt at using Movie Maker and Audacity on the same day.

A stocktake of ICT in class

I know that lots of teachers at my school shake their heads and say that they can't use ICT, that there aren't enough applications for it, not enough ways to use it, it's not applicable and so on. So I took a snapshot of ICT usage a while ago and wrote myself a little table with the date, class and usage. I thought it might be interesting. It kind of is, partly as a little picture of what can be done, and partly (and worryingly) as a picture of how far I have to go until I am integrating ICT into my classroom practice to my own satisfaction. So, here is Feb 10th....

Y9 Science: used exploratree to record the results of a brainstorm into a diagram that can then be printed off. It would have been better with a wireless keyboard - or, even better, more computers so that it wasn't just kids calling out answers and me writing them in.

Y11 Science: used a youtube clip of a brainiac experiment of walking on custard in a states of matter experiment. You know, I'd love to give students more of a chance to give authentic responses to things like this, and to take part in real discussion. We have a youtube account, I must make more use of it

Y12 Physics: used a free Yenka resource and a youtube clip to demonstate electrostatic fields. This was done with the projector and me demonstrating, but I think it would have been far more effective for students to have viewed this in small groups at computer stations (or individually) and have shared their ideas and written their explanations collaboratively using the computer instead of me just talking to the animation/clip on the screen

So, three of four lessons that day had something simple in them. But there should be more. I should be thinking bigger, less demonstratively and more participatively. I'm going to come back to this idea, taking a snapshot - and hopefully, next time, not a month after the fact - and do it again to track how deep my ideas and techniques are getting.
