Choosing the Right Medium

Overview

In lesson 17 of 30, students investigate how the choice and manipulation of media can strengthen or alter the meaning of ideas developed from whakairo traditions. They compare wood, clay, plaster, stone, metal and digital approaches, then justify a medium for their own final project using visual evidence, cultural awareness and practical reasoning.

Learning intentions

• WALT examine how media are used and manipulated to create effects in artworks.
• WALT explain how material qualities can influence the interpretation of an idea.
• WALT make an informed, respectful choice of medium for a final project.
• WALT communicate an art-making decision using appropriate visual arts language.

Success criteria

• I can identify the medium and relevant techniques used in an artwork.
• I can explain specific effects created by the material, process, scale or surface.
• I can evaluate how a medium may support or change my intended meaning.
• I can justify my selected medium with evidence and practical considerations.

Curriculum links

• Examine how media are used to create effects in artworks, including expressive, visual, textural, movement, scale and viewer effects.
• Use drawing methods, materials, techniques and pictorial conventions to develop ideas appropriate to painting and related visual arts practice.
• Produce related works that show generation, development, editing and selection within an art-making process.
• Develop understanding of art-making conventions and ideas within sculpture, including material, form, surface, scale and presentation.

Lesson structure (120 minutes)

1. 0–10 min · Provocation and recall. Teacher opens with the hook and lesson overview showing contrasting examples of whakairo-inspired or contemporary Māori art made with different media, and asks: “If the same idea were made in wood, clay or digital form, what might change?” Students complete a silent observation, then share one material effect and one possible meaning; teacher revisits prior learning about form, pattern, symbolism and cultural context.

2. 10–25 min · Explicit teaching: medium and effect. Teacher uses the medium-and-effect teaching slides to model the difference between naming a medium and analysing its use, introducing material, process, surface, texture, scale, permanence, weight, light and viewer interaction. Students annotate one projected artwork using the structure: “The artist uses ___ by ___, which creates ___ and may make the viewer ___.” Teacher stresses that students should discuss whakairo traditions respectfully, avoid treating customary forms as decorative motifs, and distinguish informed engagement from copying.

3. 25–45 min · Comparative artwork analysis. Teacher distributes the medium comparison and analysis sheet and directs students to work in pairs with four supplied artwork images. Students record the medium, describe how it is applied or manipulated, identify specific effects, and explain how the material contributes to interpretation. Pairs rank the artworks from most to least materially effective and prepare one evidence-based response. Teacher conferences with pairs, checking that responses move beyond unsupported adjectives such as “cool”, “strong” or “interesting”.

4. 45–60 min · Gallery discussion and critique. Teacher displays the comparison prompts and discussion slide and facilitates a structured discussion of selected pair responses. Students compare interpretations using “I notice…”, “The evidence suggests…” and “Another possibility is…”. The class considers how carving, modelling, casting, assembling, painting or digital construction can communicate different relationships to whenua, whakapapa, identity, memory or place. Teacher records strong analytical verbs and material-effect connections on the board.

5. 60–70 min · Break and reset. Teacher pauses the lesson, protects artwork images and prepares material samples or photographs for the practical decision-making task. Students take a short break, then return to their working groups and collect their developing project ideas from the previous lesson.

6. 70–100 min · Medium testing and decision-making. Teacher establishes stations with safe samples or photographs of wood, clay, plaster, stone, metal, paint, found materials and digital processes; students rotate through selected stations rather than handling hazardous tools. Using the material-testing instructions, students make quick thumbnail sketches or process notes showing how their own idea might appear in three different media. They assess each option for expressive effect, texture, scale, durability, available skills, time, cost, safe practice and cultural appropriateness. Students complete the recommendation section of the medium comparison and analysis sheet, selecting one primary medium and one viable alternative.

7. 100–120 min · Justification and exit reflection. Teacher models a concise justification and displays the justification model and plenary questions. Students write and share a 100–150 word recommendation: “I will use ___ because… This will create ___ by… This supports my idea about ___ because… A limitation is ___, so I will…”. Students finish with the Visual Arts Elements Planning Template to organise their selected materials, intended effects and next practical steps, then submit the worksheet for feedback.

Resources

• the complete lesson slide deck
• the medium comparison and analysis sheet
• the Visual Arts Elements Planning Template
• Projector or interactive display
• High-quality images of relevant customary, contemporary and student-appropriate artworks
• Safe material samples or photographs: wood, clay, plaster, stone, metal, paint and found materials
• Students’ previous project planning and development work
• Pencils, erasers, coloured pencils and A3 paper
• Board or shared digital workspace

Assessment

• Formatively assess pair analysis for accurate identification of medium, manipulation, specific effects and supporting evidence.
• During station work, question students: “What will this material make the viewer notice, feel or understand?” and “What evidence supports that choice?”
• Collect the completed recommendation and planning template. Exit responses should identify a medium, intended effect, evidence-based reasoning and one limitation or next step.

Differentiation

• Provide the worksheet sentence frame, a material-effects word bank and a worked example for students who need writing support; allow oral rehearsal before writing.
• Use mixed-ability pairs and provide enlarged, clearly labelled artwork images. Students may dictate or audio-record their justification before producing a written version.
• Support EAL learners with visuals and explicit teaching of terms such as medium, manipulate, texture, surface, scale, permanence, effect and interpretation.
• Extend confident students by requiring comparison of customary and contemporary contexts, or by evaluating how changing scale, process or presentation could deliberately challenge their first interpretation.
• Ensure cultural discussion is mana-enhancing: use reliable contextual information, acknowledge the difference between whakairo and personal contemporary responses, and invite students to explain rather than claim authority over Māori meanings.
