Project Report – Process Book: Topic S1 2021
You have two choices for the topic:
A) State of Australia’s Early Childhood Workforce: Is it in Crisis?
The early childhood workforce faces number of challenges, such as inadequate pay, lack of recognition, and lack of career advancement (Cumming, et. al. 2015). There are also numerous studies and reports describing these challenges.
• Challenges in Early Childhood Education and Care. https://www.cela.org.au/wpcontent/uploads/2019/05/Broadside-May-2019.pdf
• Australia’s Early Childhood Workforce Crisis: Teachers are Quitting in Droves. https://apolitical.co/en/solution_article/australias-early-childhood-workforce-crisis-teachers-arequitting-in-droves
• Early childhood education workforce issues in Australian and international contexts.
https://education.nsw.gov.au/content/dam/main-education/early-childhood-education/working-in-earlychildhood-education/media/documents/Workforce-Literature-Review.pdf
In this project, you will be designing and building a visualisation to help us realise the impact of these challenges. In particular, we would like you to focus on visualisations of recent and/or ongoing issues in the early childhood sector. Your visualisation might be aimed but not limited to any one or more of the following:
• help people understand the demand and/or impact of lack of early childhood workforce
• help people understand the impact of session hours on the early childhood workforce’s ability to receive a full-time equivalent role
• help people understand the impact/importance of the early childhood workforce

Outcome Data Elements
As Data Scientist you will need to become familiar with a variety of ways to display data and the terminology used to describe the different elements of a visualisation. For example, we will look at how well you; appropriately identify and describe data types in the data set and how they might be represented graphically.
In this part of the assessment we will look at how well you evaluate a visualisation according to visualisation and data encoding guidelines and the context of the visualisation (e.g., the audience and purpose of the vis).
For example, we will look at how well you understand;
application of data visualisation 5.0 to 3.0 pts
Very Good
Describes in detail the data used in the visualisation and the encoding principles used to represent the data (e.g., The rated smelliness of each type of cheese (e.g.,
Gorgonzola, Emmental,
Roquefort , Saint Agur, Feta etc) is treated as quantitative data and
encoded using colour
saturation (i.e., different shades of blue). The deeper the shade, the more smelly the cheese.). Demonstrates an excellent understanding of how data is presented graphically. Data clean up is specified and 3.0 to 2.0 pts
Good
Identifies the data used in the visualisation and the way in which the data is to be encoded (e.g., The rated smelliness of each type of cheese (e.g.,

Good
Good understanding of visualisation context (e.g., audience and purpose) and how it relates to your visualisation design choices. Discusses the appropriateness of using visual elements for different types of data. Good awareness of data visualisation guidelines. Shows evidence of

Outcome Academic Integrity Everyone likes to be paid for work they do. In academic and professional environments, payment is not just about money, but also acknowledgment of ideas. If you use ideas or words from other writers or researchers, you must pay them by citing their original work. Failing to cite work from other authors will earn you a FAIL in this assignment. You will also FAIL this assignment if you use the words of other students in your assignment, or you give your words to other students to use. 2.0 to 1.0 pts

Needs Improvement One or more of the following: An effort is made to cite scholarly ideas, but citation style is poor and does not follow appropriate style guidelines (e.g., Harvard). Work that Turnitin detects as the same as other published work or student work will not be graded.
