Colour Mixing

Students prepare for a colour mixing exercise to works with grayscale tones in oil painting. Working only with three colours: Titanium white, black and chrome oxide green. From these three colours students make a value scale from 1- 9 working with grayscale tones from dark to light.

  • Students know the materials and can use them
  • Students use oil colours to create a value scale in grayscale

Wi-Fi, telepresence robot

The teacher is not able to be on site and joins via telepresence robot and guides the students in class.

In MTR we approach all classes with a Flipped Classroom and students have access to all the information they need online and can prepare before classes. In the basic structure of a “flipped classroom,” the students first engage the content online (through readings, video lectures, or podcasts), then come to class for the guided practice.  Real-world situations.  The teacher then guides them in class and follows their progress in class. Is present and available for the students.

Lesson Plan
Before the Lesson:


  • Prepare for the class
  • Give students access to information about the exercise
  • Make videos and teaching materials online
  • Set up the classroom
  • Let students know how they will be evaluated


  • Be prepared for class
  • Read all information online
  • Have access to all materials needed


  • Explain the exercise
  • Go over in detail what is expected of the students
  • Be clear on what is expected
  • Give examples of how to work
  • Explain how evaluation will be done


  • Create different grayscale tones using oil colours
After Lesson:


  • Evaluate the students work
  • Give feedback
  • Re-evaluate and think of ways to improve for the next time


  • Go over feedback from the teacher
  • Evaluate their own work
  • Evaluate their work in a group setting
  • Evaluate the work of other students in a peer setting
Media and materials:

All materials for students are available in MTR’s online teaching platform Moodle. Videos, links, and all information from the teacher is available online in Moodle.

    Teacher’s Reflection: With the use of Moodle and the flipped classroom approach most problems are addressed before the class and students come prepared for the class

    Student’s Reflection: “Nice to have access to the teacher and having him present in this way when he is not able to be physically onsite “

    – Why did you decide to use TRs? So, the students have the teacher present in class.

    – How did the TRs inform your lesson plan? There is no change in the lesson plan. The TR is a tool to be present

    – What shifts or stretches are you making regarding the TRs? There is plenty of space in the classroom for the TR to move around but that is something that must be addressed beforehand, and the classroom must be prepared for the TR to have access and be able to move around uninterrupted

    Lesson Plan Evaluation
    The use of TR’s has allowed for experts that are not onsite to attend classes with students. Be present for hands on teaching scenarios. Participate in the class, motivate the students that are onsite, follow their progress and be as accessible to the students as possible. The use of TR’s in MTR works very well in a Flipped classroom setting so there is really no change in the teaching methods from using the TR or being onsite.
