Manaiakalani Google Class OnAir Lesson 5 - Isometric Sketching

Click here to see the whole Class OnAir Team

Direct Instruction
Students will be learning how to sketch in 3D using isometric grid paper.
They have sketched ideas in 2D so far and need to develop their ideas in 3D. These isometric exercises will teach them basic techniques that they can apply to their own design ideas.
The teacher will use the drawing board projector to demonstrate techniques to the class while they sit round the front table to listen.
The students will then practice these techniques with one to one / small group teacher assistance where required.

The instructions were given in stages, not all at once.
The same / similar instruction s were given to two different senior classes on the same day. One was a mixed Year 12 and Year 13 class and the other was a mixed Year 1, Year 12 and Year 13 class.

Detailed Lesson Plan

Lesson Topic :- 3D sketching skills Level 1 - Preparation for chair designs - AS91067 Level 2 - Development of concept ideas - AS91342 Level 3 - Development of concept ideas - AS91630
Year Group :- Year 11, Year 12 and Year 13
Learning Outcome	To understand how isometric drawing is constructed mainly of vertical and 30” lines. To be able to visualise shapes in 3D. To be able to construct shapes in 3D using an isometric grid. To be able to use crating to construct more complex shapes. The students will learn and practice isometric sketching skills so they can produce their design developments in 3D (isometric). The Year 11 students will be using these skills to design chairs and seating. The Year 12 and Year 13 students have been drawing concept designs in 2D and will be using these skills to draw their design developments for their product designs.
Success Criteria Using SOLO	Uni structural Multi structural Relational Extended abstract To understand the basic structure of isometric and be able to construct basic / simple shapes. To be able to construct a range of simple shapes and combine them to make more complex shapes. To be able to use crating to construct complex shapes and curves in isometric. To use isometric skills to draw own design ideas, showing different views.
Links with the New Zealand Curriculum	Level 1 Curriculum Level: 6 Learning Area: Technology Strand: Design and Visual Communication Achievement Objective: Outcome development and evaluation Critically analyse their own and others’ outcomes to inform the development of ideas for feasible outcomes. Undertake ongoing experimentation and functional modelling, taking account of stakeholder feedback and trialling in the physical and social environments. Use the information gained to select, justify, and develop a final outcome. Evaluate this outcome’s fitness for purpose against the brief and justify the evaluation, using feedback from stakeholders. Achievement Standard: AS91067 Level 2 Curriculum Level: 7 Learning Area: Technology Strand: Design and Visual Communication Achievement Objective: Outcome development and evaluation Critically analyse their own and others’ outcomes and evaluative practices to inform the development of ideas for feasible outcomes. Undertake a critical evaluation that is informed by ongoing experimentation and functional modelling, stakeholder feedback, and trialling in the physical and social environments. Use the information gained to select, justify, and develop an outcome. Evaluate this outcome’s fitness for purpose against the brief. Justify the evaluation, using feedback from stakeholders and demonstrating a critical understanding of the issue. Achievement Standard: AS91342 Level 3 Curriculum Level: 8 Learning Area: Technology Strand: Design and Visual Communication Achievement Objective: Outcome development and evaluation Critically analyse their own and others’ outcomes and fitness-for-purpose determinations in order to inform the development of ideas for feasible outcomes. Undertake a critical evaluation that is informed by ongoing experimentation and functional modelling, stakeholder feedback, trialling in the physical and social environments, and an understanding of the issue as it relates to the wider context. Use the information gained to select, justify, and develop an outcome. Evaluate this outcome’s fitness for purpose against the brief. Justify the evaluation, using feedback from stakeholders and demonstrating a critical understanding of the issue that takes account of all contextual dimensions. Achievement Standard: AS91630
Key Competencies	Thinking Using language, symbols, and texts Managing self Participating and contributing
Prior knowledge	Level 1 The Year 11 students did a Jump Start course at the end of last year. We went over some of these skills then so this should be a refresher. There are a few Year 11 students who were not on that course so this will be new to them. Level 2 Some of the Year 12 students did Level 1 DVC last year, so this will be a refresher. Some of the Year 12 students did not do DVC last year so this will be new. Level 3 Some of the Year 13 students did Level 2 DVC last year, so this will be a refresher. Some of the Year 13 students did not do DVC last year so this will be new.
Lesson Sequence	Session 1 Student Activity Teacher Activity Round the front table watching the screen as the teacher does the demonstration. Use the drawing board projector to demonstrate using the isometric grid under the plain paper. Simple straight line shapes to start with. Combining shapes together. Use of crating to produce more complex shapes. Guidelines to produce curves and ellipses. Session 2 Student Activity Teacher Activity Practicing the shapes and techniques shown by the teacher. Repeat the shapes and skills to improve their skill level. One to one help and support as needed as they work. Small group and table demonstrations on individual techniques as needed. Session 3 Student Activity Teacher Activity Produce your name / initials in isometric - use the supplied block lettering sheets of needed to keep the letters simple. Individual help Ideas for what letter might look like. Project isometric grid on the board to demonstrate to whole class what ideas might look like.

Next Steps	Students will create their own step by steps using either the drawing board with the webcam, the iPads or photographs of the steps - to create either videos or presentations with steps.
Reflection and Analysis
	What went well? The students were engaged on the skills activities for the whole session. The breakdown of the skills into small chunks that they could practice before we moved on worked well as they could build their knowledge slowly and not have too much presented to them at once. What did not go so well? The students find it difficult to visualise what they are going to draw before they draw it. Some students find it hard to follow the grid lines and still draw lines that go in the wrong directions.
	What can I do better? I had purposefully not done my own rewindable elements for these skills as the next thing I want the students to do is to make their own. I had included a link to an isometric drawing video on YouTube on the class communities for them to refer to if they wanted. In hindsight, I think it would have been good to have one made by me for them to refer to on the day. To help with the visualising of what they are going to draw, I could make some 3D shapes (on the 3D printer / made on card etc) that they could look at and hold in their hands. This may help with understanding the shape before drawing it. Having an example sheet with the shapes already draw in isometric on there so the students can see what the shape is that they are aiming for might help them to understand the direction needed for all the lines in a shape.
