1. Technologies as a learning area

Welcome to 2013EDN Technologies Education. This course has been designed to help you achieve the course aims and objectives:

  1. Demonstrate knowledge and understanding of the key concepts in Technologies education;
  2. Create design challenges and computing challenges appropriate for the different learning levels;
  3. Use creative design processes to investigate and solve real-world problems;
  4. Create resources and environments that will assist in teaching Technologies Education in schools; and
  5. Develop engaging and flexible learning experiences in project based, student centred, ICT enhanced environments.

This week we are introducing the Technologies Learning Area and the nature of technologies education.

First and foremost, the Technologies Learning Area is about teaching students to think in ways they will not learn in other learning areas.

Technologies Learning Area: Ways of Thinking:

Systems Thinking

Students will learn how to think about problems as the interaction of systems, using Systems Thinking as a process for understanding how things, regarded as systems, influence one another within a whole. In nature, systems thinking examples include ecosystems in which various elements such as air, water, plants, and animals work together to survive or perish. In organisations, such as schools or classrooms, systems consist of people, structures, and processes that work together to make an organisation "healthy" or "unhealthy".

Design Thinking

Students will learn how to think about problems from the perspective of a designer, using design thinking as strategies for understanding design needs and opportunities, visualising and generating creative and innovative ideas, planning, and analysing and evaluating those ideas that best meet the criteria for success.

Computational Thinking

Students will learn how to think about problems from the perspective of a computer scientists, using computational thinking as a problem-solving method to create solutions that can be implemented using digital technologies. This will involve integrating strategies, such as organising data logically, breaking down problems into parts, interpreting patterns and models and designing and implementing algorithms.

Futures Thinking

Students will learn how to think about problems from the perspective of futurists, using Futures Thinking to identify the possible benefits and risks of creating solutions. They will use critical and creative thinking to weigh up possible short and long term impacts. As students progress through the Technologies curriculum, they will begin to identify possible and probable futures, and their preferences for the future. They develop solutions to meet needs considering impacts on liveability, economic prosperity and environmental sustainability. Students will learn to recognise that views about the priority of the benefits and risks will vary and that preferred futures are contested.

Strategic Thinking (Project Management)

Students will learn how to think about problems from the perspective of managers, using Strategic Thinking processes to develop skills to manage projects to successful completion through planning, organising and monitoring timelines, activities and the use of resources. This includes considering resources and constraints to develop resource, finance, work and time plans; assessing and managing risks; making decisions; controlling quality; evaluating processes and collaborating and communicating with others at different stages of the process. Students are taught to plan for sustainable use of resources when managing projects and take into account ethical, health and safety considerations and personal and social beliefs and values.




Technologies Learning Area Contexts

The curriculum describes the contexts that students must experience during their studies, and what you will need to plan to teach them.

Design and Technologies prescribed contexts:

  • Engineering principles and systems
  • Food and fibre production
  • Food specialisations
  • Materials and technologies specialisations

Digital Technologies contexts:

  • Information systems
  • Information technology 
  • Software engineering
  • Computer engineering

Technologies Learning Area Knowledge and Understanding

Within these contexts, there are specific content that you will need to teach, the Australian Curriculum website describes these in detail, but in summary you will teach students about:

Design and Technologies

Technologies and society: the use, development and impact of technologies in people’s lives.

Technologies contexts: technologies and design across a range of technologies contexts.

Digital Technologies

Digital systems: the components of digital systems: hardware, software and networks and their use.

Representation of data: how data are represented and structured symbolically.


Technologies Learning Area Processes and Production Skills

In addition to specific content, you will also need to teach your students how to do things, and in particular how to use a project based approach to solving problems.

Design and Technologies

  • Investigating
  • Generating
  • Producing
  • Evaluating 
  • Collaborating and Managing

Digital Technologies

  • Defining
  • Designing
  • Implementing
  • Evaluating 
  • Collaborating and Managing

ACARA and the Australian Curriculum


The Australian Curriculum website is your primary resource when planning how to teach and you will need to become very familiar with the Technologies section for this course. In particular you need to understand the Rationale, Aims, and Content Elaborations, these provide good examples for your own unit planning and activities to do with your students.



Assessment

Details of assessment can be found on the Learning@Griffith website under Assessment.
Of particular note is that some assessment occurs during tutorials in Weeks 2, 4 and 6.


Tutorial

Discussion: What is technology? what is not technology? why is it important to study?

Discussion: What were your experiences of technology in primary school?

Discussion: What is Digital Technology Education? What is Design Technologies Education?

Discussion: How will we assess your learning?




Other activities:

Rock - Paper - Scissors

This activity builds off of the classic game of Rock/Paper/Scissors, known to most students and also related to a phenomenon seen in biology. In the off-line activity students play two rounds of the game with different rules in each round. After debriefing the game, the outcomes will be discussed in the context of computer modelling by viewing a model that uses the same rules. This is followed by a brief decoding of the computer program to learn computer science concepts. 

Stickers or cards- 3 colours for all participants (to represent rocks, papers and scissors

Part 1 - (approx. 5 minutes) Assign each student a “breed” of rock, paper, or scissors, making the groups as equal as possible. Have each student choose a classmate at random and play one round of the game (paper covers rock, rock crushes scissors, scissors cut paper). Have each student who loses the first round sit down, and the remaining students continue to play until a single student is left standing. Play again (with students reassigned in equal groups), and encourage students to choose partners at random. If there are enough students and the groups are roughly equal, the “winner” should not be predictable. Change of rules: Have students play where the loser of each round changes to the winner’s breed for the next round. For example, in a match between paper and scissors, the student who was paper ‘loses’ and becomes a scissor (and the student who was scissors stays a scissor). Both play round 2 as scissors. To identify the breeds, you can have participants wear coloured hats, display a sticker or card. Continue to play until one breed wins (or is in a large majority) – again, with a large enough group, the winning breed should not be predictable. 

Debriefing the Game:
• What did you observe while playing the game? 
• Were you able to predict who would win the game? Why or why not? 
• Who thinks someone in the group didn’t follow the rules during the game? 

Part 2 - Show a computer model (approx. 5 minutes) Go to: http://www.slnova.org/GUTS/projects/9434/ for the computer model. Click ‘View Code’ button on right side. Scroll down to see the green Spaceland where the action will happen. Show the model:
1. Click the Setup button 
2. Click the Forever button to watch the action. 
3. Take note of the data boxes counting the populations as well as the graph. 
4. Run the model multiple times and have students take note of the outcomes. 
5. Can students predict the winning group?

Discuss computer modelling with students - 
• What are the benefits of creating a computer model of the game we just played? (Answers could include: all agents will follow the rules (i.e. no cheating), can play over and over again quickly, agents don’t only follow their friends the way students might.) 
• What can we do with a model that is impossible in the real world? (Answers could include: larger number of agents, fast collection of data.) 
• What are the limits or assumptions behind such a model? (Answers could include: agents all move the same way (step size, angle of turning), equal probability of interactions between agents (no clumping of breeds).)

Part 3 - Decoding the computer model (approx. 5 minutes). Have students work in small groups to look at the code and verbalise how the computer program works in StarLogo Nova. This can also be done as a large group with the code blocks projected on a screen. Below are the code blocks for the computer model made in the programming language StarLogo Nova.

This set of blocks gets executed when the user presses the Setup button in the Spaceland area. It create 30 of each of the rock, paper and scissor agents and gives them specific colors and scatters them to random positions on the green Spaceland. (click on the image to enlarge it)


These blocks define the movement procedure called ‘wiggle.’ The random blocks allows for the unpredictable movement of the agents (in this case, rock agents, paper agents and scissor agents)




Collision blocks are used for agent-to-agent interactions. In this case, when the rock agent collides with a scissor agent, the rock ‘wins.’ In this case it means that the scissor agent is deleted and a rock agent is created to replace it. The new rock agent is separated from where the scissor agent was by the command ‘forward 3.’
 

Rock-paper-scissors may be common in many ecosystems, such as coral reefs, where scientists first observed the dynamic. The strategy of producing toxins to kill or slow the growth of a competitor is called allelopathy. It occurs in many plants, marine invertebrates, fungi and essentially every major bacterial group. The toxins that one population of bacteria uses to poison others are exploited in medicine as antibiotics.
