Read full description

FrogID is Australia’s first national citizen science frog identification initiative – a project led by the Australian Museum in partnership with Australia’s leading natural history museums and IBM. Use the App to create a profile, record frog calls and match your calls to the frog calls on the app. Then upload your records to the Australian Museum frog experts for species verification. With your help we can put more frog species on the map and track changes to their species and habitats over time, and therefore monitor our waterway's health.

About

Numbers 2

Read full description

Early Years Toolbox (EYT) Early Numeracy 2 is an iPad-based assessment of children's early number understandings-now with extension into early primary school (to age 8). It assesses children's development in areas of: counting; number and measurement concepts; number order; ordinality and cardinality; the correspondence between number, digit and quantity; number lines; patterning; subitising; and more. The assessment consists of >100 cartoon scenes, in which children help the main character (Robbie Robot) solve the number problem he is facing. Items are presented in order of increasing difficulty, with a start rule based on age (requires entering age on the home screen) and stop rule after a number of incorrect responses to prevent frustration associated with overly difficult items. The assessments takes an average of 8 minutes to complete. Scores and performance bands are presented on the final assessment screen. For more precise research applications, there are options to have the item by item data sent to a user-specified e-mail address or database. For more information, brief EYT training videos, and analysis resources, please visit http://www.eytoolbox.com.au Languages embedded: English, Turkish and more in progress. About the Early Years Toolbox: The 'Early Years Toolbox' (EYT, for short) is comprised of brief, engaging game-like assessments of children’s self-regulation, executive functioning, language and numeracy. These assessments are based on well-established evidence, principles and paradigms, yet have been adapted and optimised on the basis of 20+ years of research experience working with young children.
