Making research about open questions

[This post is part of MTBoS mentoring program [2]. This is post number #2 and is related to “My favorite” topic [3].]

I work in an adults school. My official curriculum [1] stablishes that my students of the last course, ESPA 4th1, have to make an scholar’s work about anything which “involves mathematical ideas and procedures” and they have to deliver a memorandum of the following process and their main conclusions. The teacher has to guide them through the process. This is my favorite.

When I change from teenagers education to adults school, this was my main challenge. I had not done this before. After two years in the adults school, I can defend myself against this. My main constraint is the time: the time for doing the work is very limited. My course is just 4-month course and I have to teach 3 lessons. So a month per lesson. And we have one month for the work. And they have to redact in a scientific style the work and they usually do not have any idea of how to do it. So, how do I do?

  • I have 4 classes per week. In the first month, I spend one class per week to make a mock work2. We try to answer to the question: “Which is the most non-contaminant can in the market?” It serves to us to see the 5 phases in a scientific work:
  • After this mock work, I push them out for thinking their question of the work. In my opinion “Without question there is no answer to give” and so there is no possible work. After a month, if someone does not have any question, I give them a list of possible questions or topics.
  • After that, I continue normal classes and I assign them a big homework: start the research and feedback with me any progress, difficulty or decission they’ve made. In this moment I use the theorical authonomy of 18+ years persons3. I encorage to share and ask me anything in any moment, in any class, via email or in the flesh. I remember their duty to deliver the memorandum, I ask them how is their progress once a week and how close is the deadline.
  • In the final two weeks of the course, they write the memorandum. This is the most difficult thing for them. Telling things in assay mode, reasoning each step, giving reasons of each assertion and being impartial are very difficult things for them because they usually do the contrary. I have to teach them “Linguistics” instead of Mathematics.

At the end, it is worthy: each student ends with an answer to a question. The answer could be less or more “developed” (with more or less confidence in its argument) but each of them achieve to solve the question scientificly4. The following are the titles of some works (translated from catalan, their original language)5:

  • Comparison between the gregorial calendar and arabian calendar (Comparació entre el calendari gregorià i el calendari musulmà)

  1. which I think it is formally equivalent to 10th grade of USA [4]

  2. My students have not written a scientific work. If I want they to write it, they need at least one chance to learn.

  3. I suppose that we have to guide the teenagers…

  4. Obviosly there are students who don’t pass the work, but normally it’s due to their absence of work not due to the lack of reasoning in their argument.

  5. Any mistake with the translation is mine
