This is an assignment that Kristine sent to me, I think there are some good ideas here.

I couldn't figure out how to attach it as documents, so I pasted it here.

 
Jewelry 1
Project 1: Research Project and Presentation

Guidelines for written report:
! Paper needs to be three (3) pages long, plus and title page and a bibliography page (total 5 pages)
$           If pictures or illustrations are included, they do not count as part of the three pages. It would be better to include them in the oral report visuals.
                       
! Paper must be typed in the following format: 
$           12 pt. font, Times New Roman
$           .75 margins
$           double-spaced
                       
! There must be a minimum of three (3) references, properly annotated on your bibliography page
$           One reference must be from an actual book
$           One reference may be from an online source, but not Wikipedia
$           The third reference may come from a book, a periodical, or an online reference other than Wiki.
                       
! Oral Report will be 2 minutes long.  Oral Report will be taken from the written report.  
                        Half (½) of the research grade will come from the oral presentation. 
! A power-point presentation or other visual aides should be used as part of the Oral Report.

! We will spend two days in the writing lab and library gathering information and working on the reports.  Any additional time needed to complete the assignment beyond that will be up to you.

 I thought I would talk a little about engraving. I have a fair selection of gravers, round, flat, knife, and they are some of the best wax carving tools I have for my classes. I went to the wood shop teacher and he had some of his students turn handles out of hard wood scraps for them, so they are pretty nice for about $6 each. But, they are really quite difficult to use on metal. I have a fair amount of students slip and stab themselves, so for most metal engraving I have found a better way.

This is a Fordom hammer hand piece, and the tips are interchangable.
These some of the anvil tips that I have. From the left to right, they are as follows:
  1. round graver tip (I had to alter this one. I also made a finer tip graver, but it was on the tool when I took the picture of these heads. I used a sander to grind the tips)
  2. a great rounded bezel setting tip
  3. flat graver tip (also adapted) 
  4. a flat anvil head(I don't really use this that often, but it came in the kit. If anyone thinks of a use for it, let me know)
  5. a high speed carbide bur (it just happened to be in there when I took the picture)
  6.  a flat round anvil tip (very nice for setting smaller stones, in bead, box bezel, gypsy bezel, or prong sets. I also use it to mushroom rivet heads over in hard to get to places) 
  7. a domed and polished round anvil head (great for texturing) 
  8. a barrel anvil (I don't use this very often either)
I use these tips to engrave with. I also have a graver's vise which is really nice, but it was here when I got hired 12 years ago, I don't know if I would buy one now, because they are upwards of $450.
If your guys have input, ideas or questions I would love to here them.

Does anyone have a good way of polishing the edge of a piece of plate metal right up against another piece of plate when they are soldered together? I have a tumbler with stainless steel shot that burnishes pretty well, but it takes forever and I hate changing out the water every hour or so. I would appreciate any suggestions.

How do you grade student work?

I have tried several ways. I have used rubrics, I have had them turn the jewelry into me, and I look at it and grade it, and I have had students bring their projects up to me and I discuss the grade I think they deserve, versus the grade they think they deserve. The problems I have had, is that rubrics take the creativity/effort out of the equation unless I get something so complex I hate to use it. I also have to give scripted assignments; the students can't do much in the way of personal creativity.

When it comes to having the students turn their stuff in, I have to grade it right away and give it back, or they have a conniption fit. But, there are always some who aren't there to get the projects back, so I end up having the things laying around, and it seems like I always lose something, generally to theft. It was annoying and to top it off, there was always someone who was not satisfied with their grade, but they couldn't produce the project, and I couldn't defend the ruling.

When I call the students up to grade with them it seems like at least a quarter of the class is not finished and so I waste a whole period then have to do it again, and again, and again, and again(get the picture).

Now I have a white box that I photograph their work in, then I grade it from the picture. I like this method pretty well, because I don't have to worry about losing their projects and I can do the actual grading when I feel like it. Another benefit is that I have the pictures to show students examples. I put them in slide shows as I introduce new projects, and we have the pictures for critiques. The down falls are that I have to crop and adjust every picture because I want them to look good and I don't have great lighting. Then the students take pictures of the good side of things so I don't always get an accurate view of things.

This ring shows a fairly accurate view for grading. It is soldered well, and the bezel is clean. It looks great, even if they could have filed the wire ends a little better.

This ring look pretty good from the picture, but I can't see what the band really looks like. Then I found out later that the bezel was not soldered on and the back of the band was broken.
So how do you grade?
