Mathematics learning support

Videos to address student questions as they arise

Ellen Appleby and Antony Dekkers, Mathematics Learning Centre, CQUniversity

Scaffolding original principles

Scaffolding (original principles)

  • Principle 1 and 2 – Diagnosis and initial support

  • Principle 3 – Adaptive or dynamic feedback cycle

  • Principle 4 – Demonstration of learning

  • Principle 5 - Fading

Application of these principles

Application of these principles

  • TabletPCs can provide fast individualised feedback to students thus creating a dynamic feedback loop that can be faded as the student(s) demonstrates the learning.

Fast individual feedback through videos the advantages for students

Fast individual feedback through videosThe advantages for students

  • Gives fast response from lecturers to requests/problems through email

  • Can be tailored to individual problems by the lecturer

  • Can be stopped, started rewound

Fast individual feedback through videos the advantages for lecturers

Fast individual feedback through videos The advantages for lecturers

  • Gives fast response to student requests/problems

  • Can be tailored for individual students or as a bank of resources to meet common problems

  • Videos are quick and easy to make

  • Little preparation

  • Rarely require editing

  • Emailed directly to

    the student (file size is small)

The tools

The tools

  • Tablet PC with microphone

  • Camtesia® Software (or screen and audio capture software)

  • Tablet PC scribing program such as

    • Windows Journal

    • Word

    • Powerpoint

    • PDF Annotator

    • etc

The process using camtesia

The process using Camtesia®

  • Open Camtesia

  • Set it to record screen mode, turn off audio and video camera

  • Open a screen in a tablet scribing program (egWindows Journal®, Powerpoint®, Word®, PDF Annotator®)

  • Record the video of the scribed calculation/lesson first

  • Then add the audio (Add Narration) to the video (this is more controllable)

  • Check audio fits video (can edit easily)

  • Publish video to custom, either as wmv (Windows media player)

    or Quicktime file

Example file 972kb time 1 40

Any questions

Any questions?



  • Scaffolding – what does it really mean?

  • What is effective scaffolding?

  • What are the processes of scaffolding?

Original intention of scaffolding

Original intention of scaffolding

  • The formulation of this notion was designed to explore the nature of the support that an adult provides in helping a child to learn how to perform a task that, alone, the child could not master.

  • (Wood, Bruner & Ross, 1976, cited Wood and Wood, 1996)

Effective learning support

Effective Learning Support

  • “Bloom concluded that face-to-face instruction leads to an improvement of two Standard Deviations over conventional class teaching (i.e. about 98% of individually taught learners score above the average for group taught). If computer-based systems could be designed to capture even part of this benefit, then the educational rewards of the research could be highly significant.”

  • (Cited in Wood & Wood, 1996)

Scaffolding the term

Scaffolding – the term

  • Scaffolding as a term has become overused and its meaning has become unclear and has lost its significance.

  • It has become a proxy for any cultural practices that were a form of mediated learning support that included people, artefacts, media, computers and other ICTs.

  • (Pea, 2004)
