It may seem 'normal' that practical work should only be carried out in a laboratory, but is this systematic organization always justified? Can we question this principle? Some have already taken the plunge and set up approaches that enable them to work remotely.
We'd like to give you some ideas about the extent to which, and the conditions under which, remote practical work can be envisaged, as well as a few examples of concrete achievements, based on the informal riposte créative workgroup and the Prodagéo blog article on the subject.
Objectives
Before defining how to organize the practical work sessions, it is essential to specify the objectives and assessment methods to ensure the overall coherence of the activity. It would seem that practical work can have two main objectives:
- Comparing theory with practice, or supplementing theory with practice;
- To develop professional skills, which may be physical or intellectual: reasoning, approach, collaboration, etc.
Can you define your objectives for each of the practical sessions you prepare? It's highly likely that several manipulations will enable you to work on the targeted gesture or highlight the phenomenon under study, and perhaps some can be carried out outside the classroom?
Assessment
Once the objectives have been defined, the question arises of how to assess the students' practical work. It's not a question of grading the student's work, but of providing feedback to help him or her progress. This feedback can be provided by 3 types of trace:
- Production: which can be a finished product, a text, audio, photo or video document, a measurement chart, a curve, etc.
- The process: based on observations, intermediate documents, which can be very different from an a posteriori presentation of the process, which is often sanitized and presents only the result of the process, without addressing all the stages;
- The purpose: reflecting the student's reflective analysis of what he has learned, his self-assessment and the feedback he can provide on his work.
By making the link with the targeted objectives, it appears that a skilful mix of these 3 elements is often necessary, and it remains to be defined which observables the teacher will choose to enable the most relevant evaluation possible.
Distance-related difficulties
Two factors can complicate the implementation of distance practical work:
- The need for specific materials or raw materials, which may be 'raw' data, raw materials, tools, etc.
- Ongoing monitoring by the teacher to support learners in their learning process.
We'll look below at the useful tools and strategies that can be put in place to overcome these constraints to a greater or lesser extent.
Useful tools
- An Office suite: to produce reports, data analyses and presentations (standard format for practical work reports).
- An enriched editor: which can be collaborative, enriched by video/audio (e.g. CodeCast, which enables the teacher to present the computer code to be produced, and the learner to stop the presentation at any time and take control of the code editor, etc.).
- Photos, audios and videos: to present your work, your approach, a professional gesture, the intermediate stages, etc.
- A virtual classroom tool: Repertoire
- In workshop/group mode: for group work, where the teacher can move from group to group and intervene if necessary.
- In group or personal follow-up mode : for work analysis and feedback, by the teacher or other learners.
- A forum: specific to the course, for learners to help each other, or for the general public (e.g. Stack Overflow or Stack Exchange) to find information and transpose answers to my particular context.
- A smartphone that's a Swiss army knife, loaded with sensors that can be useful for 'measuring the world' and capturing traces (photo, audio, video).
Some practical approaches to distance learning
- Several training organizations offer the 100% distance learning CAP in pastry-making. They use videos to present professional techniques, and rely on virtual classrooms to monitor learners throughout their training. Expert analysis of the production is complemented by an exchange between the trainer and the learner, enabling the trainer to retrace the production process, the difficulties encountered and the strategies implemented, and to provide constructive feedback to help the student progress.
- The Cachan IUT is equipped with a numerically-controlled machine emulator, making it possible to learn safe machining without the need for a real machine. It can also be used outside the workshop.
- EPFL has developed the R2T2 project, challenging pupils and students to program Thymio robots: robots, physically present on EPFL premises, are available to test programs developed around the world. These robots can be programmed, among other things, using the scratch language, which federates a very active community around a space for capitalizing on achievements where everyone can share their programs and creations.
- The University of Colorado Boulder offers a virtual laboratory with over 150 interactive simulations covering a wide range of scientific and technological fields. These simulations can be used to complement theoretical teaching.
- The University of Grenoble offers LabNbook, a shared laboratory notebook. It enables students to work together (in the lab or remotely), integrating their approach, results, analysis and teacher feedback into a single document.
- In his talks(here and here) with Chrsitophe Batier, Jean-Marie Gilliot summarizes a number of other approaches based on students' smartphones, with challenges, the question of sharing measurements, participatory science, etc...
In conclusion
These different approaches show that it is possible to work on professional gestures from a distance (as in the case of pastry-making), and to a certain extent, do away with complex equipment (by relying on smartphones, emulators, simulations). There are also a number of ways in which support can be provided.
Practical work of this kind, "out of the lab", seems conceivable. They can even provide added value by integrating collaborative methods and being rooted in students' everyday lives, which can be a real source of motivation and commitment. Last but not least, teachers need to be well-equipped to support students in their approach, and to be rigorous in monitoring them effectively and regularly over time.
