Who are my learners and what do they already know? Diagnostic testing can be conducted at the start of the unit to identify what students already know and areas that require development. Diagnostic testing may include asTTLe, PAT or topic based assessments. Resources from the ARB can also be valuable for this purpose, for example a task on finding information at levels 4/5. Using diagnostic testing will give the teacher a good idea of the skill level of the students within the class. Diagnostic testing should relate not only to the students literacy ability but also to their knowledge of the topic being studied. Using the data available identify specific areas on which to focus. For example ‘Finding information’.
School Curriculum Outcomes This unit develops the values and Te Kawa o Te Ako from the school’s current strategic plan, in particular the value of respect for self, others and the environment. Kaitiakitanga, the obligation to protect and nurture all living things is particularly relevant and is developed through the study of issues facing the earth and its inhabitants today and how we can create a sustainable environment. Through learning about the environment and why we must look after it students develop a greater awareness of these values and the values that they themselves place importance on.

Assessment and Evaluation

 (What is the impact of my teaching and learning?)

Literacy learning Outcomes:

Students will:

  • use their writing to explain concepts, processes, phenomena, theories, principles, beliefs, and opinions (their own and other people’s) that are relevant to the curriculum task
  •  use language, text structures, and media that are appropriate for their purpose
  • Use key vocabulary in oral and written responses

Social Studies Outcomes:

  • Describe factors putting pressure on the environment
  • Explain the consequences of pressure on the environment
  • Understand different points of view on an environmental issue

Within this unit there are numerous opportunities for formative assessment. The final assignment along with the essay should be used for summative assessment and reporting on. This can be assessed for botht the literacy and specific Social Studies learning outcomes.

It is important that teachers use formative assessment to inform teaching practice.

Effective formative assessment should be used to inform the learning and teaching process. Teachers should be using formative assessment to guide the next steps in a teaching and learning sequence and to assess where students’ are achieving.

https://arbs.nzcer.org.nz/arbs-and-assessment-learning

Written feedback should be provided to students for the essay tasks (both in the Population study and individual inquiry) in order for them to identify the next steps and what they have done well.

Teachers should be conducting formative assessment by asking themselves the highlighted questions (in blue throughout the unit) each time a strategy is used. Is it working? Are the students actively engaged? Are they progressing as expected? Are students acting on feedback to improve their learning? Do I need to review this strategy and use it again?

Teachers should also be regularly monitoring the students learning logs to identify specific areas of need and to gauge interest.

Students are provided with choice in the selection of :

  • their inquiry topic.
  • their ability to choose the way in which they present their findings.

By giving students choice they are able to choose topics and presentation formats that interest them and utilise their individual strengths. By providing students with an opportunity to present their findings to an audience they develop in confidence and it also provides a meaningful sharing of knowledge.

Self assessment is also crucial through the regular completion of learning logs and also the self assessment matrices attached to both the essays and the inquiry assignment. Self assessment allows the students to critically reflect on their own learning.

ARBs can also be used as diagnostic assessment. For example, if students are already skilled at finding information relevant to the question then less time can be devoted to developing this skill in class and more devoted to another area for development. Diagnostic testing enables teachers to make decisions relating to the specific learning needs of the class.

Provision for identifying next learning steps for students who need:

  • further learning opportunities
  • increased challenge
Students can be provided with numerous opportunities for increased challenge over the course of this unit. Some students may not require the scaffolded essay writing process and instead may choose to write their essay without it. Another opportunity for extension arrives in the inquiry assignment where students may develop their own research questions to answer the overarching question. Students are also able to choose their method of presentation which enables them to build on skills and talents they may have in a particular area.

Tools or ideas which, for example might be used to evaluate:

  • progress of the class and groups within it (including literacy progress)
  •  student engagement
  • leading to :
  • changes to the sequence
  •  addressing teacher learning needs

Learning logs – These enable students to reflect on a regular basis on their own learning and understanding. Teachers are able to use these logs to identify next learning steps, reteaching points or ways in which the teaching and learning process could be modified.

Writing samples can be used to assess where the students are achieving and next learning steps. For example, an essay may show that the students are able to write in paragraphs but that they are unable to link their thoughts and ideas.

Throughout the course of this topic there may be areas which particularly interest students. For example in the ‘Pressure on Living Things” section students may display a desire to learn more about endangered species and the threats they face. This may provide an opportunity for greater learning and progress as it is driven by student interest.

It is important for students to have the opportunity to revisit strategies and ideas that they found interesting or particularly useful. This also enables students to develop a greater understanding of when and where they can use a particular strategy to assist them and in a cross curricular context.

It is important to ask the following questions as found in Using Inquiry to Plan Secondary English Programmes as they are relevant in any subject or curriculum area. They enable the teacher to reflect on the teaching and learning process and ways in which it could be improved/changed to improve student success.

  1. Did your students demonstrate understanding of learning outcomes?
  2. Are there particular groups of students whose needs are not being met?
  3. Which texts/topics/tasks/activities did students engage with?
  4. Did all students complete all assessments?
  5. Were there any issues around absenteeism at any particular point during the programme?
  6. Could this have impacted on learning?
  7. What are the implications for our future planning?

Big Idea – The size, shape and direction of the shadow changes during the day
 
The teacher reviews with the class the concepts, definitions, word banks and experiences explored to date.
 
Students will write an explanation as a result of the investigative activity My Shifting Shadow.

Resources for teacher modelling, scaffolding and student participation in understanding the structure of an explanation can be found at:

MY SHIFTING SHADOW

What you need

  • A sunny spot on an asphalt area that will be exposed to the Sun all day.
  • Some chalk
  • Digital camera

What You Do

Go out at 9 a.m. and with a partner stand in one spot and have your partner trace your shadow.
Repeat this in a different place and trace your partner’s shadow. Measure the length of both shadows.

Repeat this on the hour until 3 p.m.

Take a digital photo of each set of outlines at the end of the day.

Each child can graph their set of shadow lengths.

Why do the shadow lengths change during the day?

What To Look For

That the student understands that it is the relationship of position of the Sun and the angle of the Sun’s rays striking the Earth that causes changes in the shadow.

The position of the Sun changes as the Earth spins.

Opportunities to explore

Could we use this information to tell the time?

What is a sundial?
 
Assessment of learning in this unit

The assessment task for this unit will require the students to apply the scientific concepts and vocabulary used over the series of investigations.

Each student will be required to apply their knowledge to use the Before Before After After framework to sequence the photographs of shadows over the course of a day matching the shadow position and length to times during a day.

Teddy Bear Shadow Template (PDF 1MB)
Teddy Bear Shadow Assessment Teacher Notes (PDF 221KB)

Students will then write an explanation that will require them to explain the movement of shadows in relation to an object over a day. It is expected they will use vocabulary and science specific vocabulary tin their explanation.
 
To confirm their conceptual understanding of the light source’s (the sun’s movement) they will position the sun in relation to each shadow on their poster.

Assessment opportunities by the teacher using the teaching as inquiry framework

Observation of students’ conversations and working in groups

  1. What information about the student’s learning and knowledge have I gained?
  2. What are the implications for my teaching
  3. What are the next learning steps - conceptual understanding, vocabulary, learner needs?

Learning task 2: Making shadows

  1.  
    1. Explain that each student will use chalk to trace the outline of their partner's shadow on the playground.
    2. Remind students to never look directly at the sun, but to concentrate on the shadows.
    3. Have the students in pairs find a place in the sun and make shadows by standing, running, making body shapes, and so on.
      • Begin by outlining the partner's shoes or feet. This is important as the students are going to trace shadows at different times throughout the day.
      • Make sure that every student gets the opportunity to create a shadow. 
  2.   

    When the students have completed the outside tracing, have them draw their partner, their partner's shadow, and the location of the sun.

    Model writing a caption for the shadow tracing. Have the students write a caption for their drawing. 

    NB Throughout the unit take digital photos of the students and shadows to use later for discussion and motivation for writing. Make into a book or a wall story "Our Book Of Shadows". 

  3.  

    1. Two or three hours later (or the next day), after students have completed their first shadow tracings, have the students go outside again to observe their shadows and make a tracing of what they now see.
      • Ask students to predict if their second shadow tracings will be the same or different from the first shadows they drew. Record their predictions.
      • Return to the playground. Have the students reposition themselves in their original places, using their feet or shoe outlines as a guide.
       
    2. Discuss with students what they observed:
      • Did anything change?
      • What looked different?
      • How many shadows changed?
       
    3. Revisit previous predictions. Discuss how many students predicted correctly.
      • What do you think made the shadows?
      • How can you explain that?
      • Did the sun move?
      • Did we move? (Explain to students that shadows move as a result of the Earth's motion.)
       Teacher and students: What else have we learned and need to add to the KWL chart? Have we answered our first questions? Have we any new questions?

    Have students discuss the information they have discovered about their shadows' lengths and other observations on shadows made by the sun at various times during the day. Teacher and students work together to complete a table for this information and then write some concluding sentences. Read and display these in the class. 

  4.   

    1. In the classroom have students observe the sun shining through the windows and look to see where shadows are being made. Ask the students to explain to each other, in pairs, why they think shadows happen.
    2. Students view this animated ARB resource on how shadow length changes as the sun moves into different positions. Teacher and students work together to the answer the questions.

     

    Using different objects encourage students to create, trace, and manipulate shadows.

    Encourage students to question: 

    • How can you "make" a shadow?
    • What is the light source?
    • How is the shadow similar to the object you used to make it? How is it different?
    • How can you change the size of your shadow?
    • How can you change the shape of your shadow?

     

Learning task 2

Oral anecdotes - personal "spider" experiences

In pairs, students discuss their experiences with spiders. Share with another group. Encourage active listening and questioning.

Role play. Students act out some of their spider experiences/feelings. Talk about what to look for when someone is scared eg How do they stand? How do they breathe? What do their eyes look like?

Construct two graphs to depict students' ideas and feelings toward spiders before and again at the end of the unit. Discuss why some people are afraid of spiders.

Spiders and insects

As a class discuss:

  • What is the difference between an insect and a spider?
  • What do we know about spiders?
  • What do we want to find out about spiders?
  • Where would we find spiders?

 Chart responses, eg.

  • What do spiders need to spin a web?
  • How do spiders spin a web?
  • What do spiders eat?
  • Where do spiders get food?
  • How do spiders get food?
  • Do other animals eat spiders?
  • Are spiders themselves food?
  • How do spiders hide from their enemies and not get eaten?
  • What colour are spiders? Are all spiders brown? Black? Red?

Facts about spiders:

Spider Facts

Assessment Resource Bank activities

Features of insects and spiders
Students match features to spiders or insects.

Life cycle

Read and discuss the life cycle of a spider.

Close reading/Shared reading

Use models of explanation (see  The Best Nest and  Why Does Earth Need the Atmosphere?) writing to share with the class. Read the explanation with the students. Talk about the explanation - How do we know this is an explanation? What impact does the explanation have on us as the readers? How would the author have gathered this information?

  1. Discuss and identify which explanations are about the "why" and which are about the "how". Talk about what it is in a sentence that tells us about these differences.
  2. Identify action verbs and discuss their functions in organising explanations. Action verbs can be identified and discussed in terms of their function as part of a
  3. sequence of processes that explains how things happen or work, or which explain why one action causes another action.
  4. Discuss use of conjunctions to link groups of processes, eg. first, next, then, when, because, so that, therefore. See Exploring Language - Complex Sentences.
  5. Continue, each day, to read about spiders and gather information about spiders.
  6. Discuss and list facts about spiders found in the reading. Record on large chart.
    • How are spiders special? (Arachnids)
    • What can we say about them?
    • How could we observe spiders?
    • Discuss how we could safely (for the spider) set up a vivarium?

Assessment Resource Bank activity

Features of a spider

Learning task 3

Instructions/Explanations

Close read instructional/procedural texts to the students.

Assessment Resource Bank activity:
How to Make a Plaster Mask
Provide opportunities to discover the differences and the similarities between explanations and instructions:

  • Explanations and instructions include a sequence of events.
  • Instructions usually don't state reasons for the events.
  • Explanations involve the stating of reasons for an activity or process.

Focus attention on the need to add reasons when writing an explanation. Together list the language and text features that will be the focus for later writing.

Observation

Set up a vivarium for student observation. Students use a magnifying glass to observe spiders and write a brief explanation of their observations. Discuss how the vivarium may help to find answers to our questions: What we want to find out about spiders.
Collect, observe and make notes on changes for several days.

  • Have any of the spiders died? Why?
  • Have you seen any of our spiders with eggs?
  • Have any spiders been born?
  • Where did the new spiders come from?
  • Where are the eggs?
  • What did you observe through the magnifying glass?
  • At the end of a week summarise the information from the observations. What have we found out about spiders?

Outside the Classroom (this could be a homework activity for a week). The students keep a record of the number of different spiders they see.

Information gathering

Shared reading - read and discuss how the spider uses a web to catch prey.

Discuss different types of webs and how different spiders catch their prey. Discuss how camouflage helps spiders catch their prey and also helps them hide from their enemies.

Shared writing

Teacher models writing an explanation: "How a spider catches its prey". Teacher introduces the explanation_checklist (RTF 16KB) Students identify the checklist points using the teacher modelled writing.
Teacher models how to use a flowchart or  cluster diagram, organising ideas into sequential order, thinking carefully how to start and end the explanation. Model how to select the best and most relevant ideas. Ask students for ideas, encouraging them to participate in the modelling process. Talk about the audience for their writing. Who will read it? How will this affect your planning?

Spider venom

Read How does a spider use its venom?
Discuss:

  • Are all spiders harmful to humans?
  • Do all spiders bite?
  • Which kinds of spiders have been known to kill humans with their bite?
  • If not all spider bites cause death, in what other way can spider bites be harmful?

 

Students complete venom activity.

Using the explanation model students brainstorm and plan an explanation: "How a spider uses its venom"
Students plan and write their draft explanation and with a peer use the explanation checklist. Students peer_conferencing (RTF 21KB) with each other, commenting on and questioning each other's explanation.

Learning task 3 - Examine an exemplar

Learning intention(s)

Students will be able to:

  • identify the main ideas in the exemplar
  • describe the language features in the exemplar and their effects.

a) The following visual exposition exemplar is based on the Shakespeare play, Romeo and Juliet. The visual exposition focuses on specific themes from the play and has been created without sound effects, voiceover or music.

While reading the exposition for the first time, consider the ideas it communicates and record the pressures that were faced by Romeo and Juliet.

NOTE: This should be viewed in 1080p for maximum clarity of text.

Record the colours and images that were associated with these pressures.

  • How was layout (where things were placed) used to associated particular images with ideas and other objects in the panels?
  • Why do you think these colours and images were chosen? How might viewers respond to them?
  • What other visual language features were there in the exposition and how did they communicate ideas from “Romeo and Juliet?”
  • Write a short phrase that describes the themes that were presented in the visual exposition.
  • Overall, what do you think were the most effective aspects of the exposition?
  • How could it be improved?

b) Read over the annotation for the exemplar (Word 33KB) and discuss the techniques that stood out.

c) This exemplar has no sound effects, music or voice-over to create effects and communicate further meaning. There are a number of ways these techniques could be incorporated into the text.

Explain how you could use voice-over, music and/or sound effects to further communicate the ideas from “Romeo and Juliet.”

Learning task 6 - A progression of ideas

Learning intention(s)

Students will be able to:

  • Explain how a progression of images and text can develop and communicate complex ideas.
  •  Explain which visual techniques you will use to communicate ideas and how these work.

a) An effective way to communicate complex ideas is to start off simple and add detail and explanation as you go. Your audience or readers are more likely to understand complex ideas if they are communicated in a progression - starting out simple and adding necessary detail as the text progresses. Visual expositions are particularly good for this as you are able to show a progression of shots or panels (one after another) to build up the audience’s understanding of your reading of the ideas from the source text.

Each panel may be composed of a number of images and text and can be divided into distinct parts. Within these parts you can plan the progression of a number of different ideas which all contribute to your thematic focus. NOTE: refer back to the exemplar and its annotation for more on its four main parts: background, foreground, sky and text.

b) Part of the challenge with communicating complex ideas is to figure out what simple idea to start with and then how you can compose your panels and use visual language techniques to fully communicate the various meanings and ideas.

Consider what progression of images from panel to panel you could use to best develop meaning. Don’t worry too much about how you will produce these images, just imagine the most ideal images you would have in it.

Consider how the “Romeo and Juliet” exemplar uses the following techniques and decide how you will use:

  • Dominant images for your panels - what will you use here?
  • Background colours or scenes - what mood and other meanings do you want to communicate in each panel and overall? Is there a change in the course of the source text and then in your visual exposition? What colours will you use for your text?
  • Visual symbolism - what things, that your viewers will understand, can you use to stand for some of the important ideas from the source text?

Complete the tutorial and planning template on “ Planning for a progression of ideas (Word 49KB) .”

Learning task 9 - Decide on the best tools

Learning intention(s)

Students will be able to:

  • Justify your your use of tools given your expertise and the desired effects.

a) Now you should consider which tools will be the best for developing your visual exposition. There are some tools listed below to help you with this. Some are open source software, others are websites that provide tools that are usable online.

Whichever tools you use, it is likely you will need to manipulate graphic files by cutting out images and combining them with other images and using text and colour on your visual exposition.

b) When converting images to film and editing video, most tools are fairly similar to use. Windows Movie Maker and imovie in particular are simple to use for stringing together images and/or video and for adding sound.

If you are working in a group, you should aim to use the existing expertise within your group and build further expertise individually. You may decide to assign roles to each group member depending on which tool they wish to use. All group members should be involved in the planning and understand how the ideas are being developed and communicated in your visual exposition.

  • GIMP - a powerful graphics manipulation tool.
  • Official GIMP tutorials (beginner tutorials will get you started)
  • Windows movie maker - A easy to use video editing tool. Can be downloaded from the Microsoft website.
  • Audacity - an open source sound recording and editing tool. Easy to record sound files for voiceover.
  • Audacity tutorials
  • Inkscape - A powerful vector editing tool. Good for creating images from scratch. An electronic alternative to drawing your own images and scanning them.
