    <p>Hi all,</p>
    <p>My experience so far is to have teams or individual students come
      up with their own proposal. Teachers evaluate these and proposals
      shouldn't be identical. During a project or an assignment students
      are encouraged to work together and share knowledge. And if they
      copy stuff from each other that's okay as long as they are open
      and honest about this. During or after a project the teams or
      individual students are asked to explain how they did "things".
      Also students or teams are asked to make a screencast or a
      tutorial.</p>
    <p>So in the school projects that I've been involved so far the
      teachers don't chase cheaters, they just check whether the student
      has understood the material.<br>

        <div>The cookie cutter or lock step approach that exists in some
          teaching environments does lead to 'boring' copycat
          assignments. I've also taught practical technology, like
          woodwork & electronics, and within that context the
          student may have developed these skills and knowledge before I
          ever see them. So the focus has to be different. There are
          that many tutorials online these days that cover various
          skills.</div>
        <div><br>
        </div>
        <div>Personally I avoid just evaluation technical proficiency
          and take the view that Blender is a tool for expressing
          artistic intent. I get them to provide a boarder scope of
          evidence to demonstrate their skills. For example; Using
          Blender's modeling & 3D Printing tools I get the students
          to;</div>
        <div>
          <ul>
            <li>develop a concept on paper,<br>
            </li>
            <li>provide feedback on other's work, &<br>
            </li>
            <li>create model for 3D printing.<br>
            </li>
          </ul>
        </div>
        <div>To drive their creativity you could provide each student
          with a randomly generated mesh to incorporate into their
          design, to provide a unique key that can be linked to each
          student.</div>
        <div><br>
        </div>
        <div>I would suggest that when creating tasks that use Blender
          make it only one part of the assessment.</div>
        <div><br>
        </div>
        <div>For example; Creating a short 3D Animated sequence could
          also include Script writing, Storyboarding, Design sketches,
          Modeling, Animation, Composition, Sequencing. Of which about
          half happen in Blender. In the classroom I make regular
          observations of student progress to track where they are. For
          online teaching you could request a regular snapshot, and
          response with feedback.</div>
        <div><br>
        </div>
        <div>In the end, someone who cheats is only cheating themselves.</div>

                          <div>
                            <div>
                              <div>
                                <div>The first thing I thought about
                                  when I read this message is the point
                                  that Ton refereed to. If Open Source
                                  and Creative Commons has shown us
                                  something is that copying is not bad.
                                  Saying that you copied something and
                                  not acknowledging it and the work of
                                  someone else, is. Basically it's
                                  lying. But using someones work and
                                  building upon it is not bad, and is
                                  definitively and important skill set
                                  in Blender specifically. Is just
                                  impossible to tell, how many times I
                                  have reused others work as well as my
                                  own. Just think of libraries.<br>
                                </div>
                                Of course it is important to develop the
                                skills of building something from
                                scratch, but in order to do that, one
                                must be really motivated to do it, so
                                that thing that is going to be build
                                from zero, must be something one really
                                relates to on a personal level, so it
                                must have one's signature. Even in that
                                situation, is way faster to just take
                                some parts or solutions already done.
                                Taking a solution made by some else,
                                also makes me think on how they solve
                                the problem and I can learn from that.<br>
                              </div>
                              The students must be encourage to make
                              their own projects with their distinctive
                              signature marked by their own ideas and
                              tastes. If the projects they are to
                              deliver are way too similar, and it's
                              easier to just copy the file and put my
                              name on it, I think the project is not
                              making them learn much anyway, but just to
                              repeat a set of instructions that deliver
                              an expected result. In art in general and
                              in Blender in specific, you have to be
                              able to solve the unforeseen problems that
                              arise always.<br>
                            </div>
                            So, to grade that kind of work is harder,
                            but the learning is completely guarantee to
                            be valuable and enjoyable.<br>
                            <br>
                          </div>
                          I love this subject, but I guess is more
                          suited for a pedagogy specific panel.<br>
