This app has been carefully written for Year 8 students (Victorian Curriculum - 2019). The aim of the app is to assist students in investigating and understanding the exciting and very important world of Mathematics. This app fully implements the intent and scope of the Victorian Mathematics Curriculum (A curriculum mapping is included). Numerous worked examples support carefully graded exercises to cater for a wide range of student abilities and to ensure that all students experience success. Each module contains algorithmic coding activities that solve problems related to the topic Extensive and diverse range of supporting activities, within the app, include: - Open-ended rich tasks - Investigations - Technology in mathematics - Mental computation - NAPLAN preparation - Mathematics competition preparation - Mathematics puzzles - Mathematics games - Mathematics tricks - Mathematics history - Mathematics careers This app was written, by the author, in the programming language C#. The app thus has a rapid response and is able to include features not available in standard digital readers. For example: - Relevant worked examples are placed beside exercises - Worked examples can be covered with a single tap or click - The answers to an exercise are available with a single tap or click. - Review flash cards summarising the topic are available with a tap or click - Mental arithmetic questions, in audio, can be played with a tap or click - Videos supporting each unit, within a topic, can be accessed with a tap or click - Hints on how to succeed at mathematicss are available with a single tap or click - Screen views can be copied to other applications, such as OneNote The author is a mathematics head with 30 years experience, an honours masters in IT education, a PhD in mathematics education, a state award for mathematics education, and extensive publishing experience. The author used a literature review of presentation of information to a learner to enhance the format of the app. Issues such as cognitive load theory, working memory theory, worked example effect, split-attention effect, redundancy effect, expertise reversal effect, etc were carefully addressed in the design and layout of the app.
