Introduction and Project Background

Sack, Jacqueline; Vazquez, Irma

Pages: 1 –3

[The project began as part of a PhD dissertation study in South Africa, by Retha Van Niekerk after she met with Pierre Van Hiele and with researchers within the Wiskobas project at the Freudenthal Institute in The Netherlands. Her work with Ton Lecluse, author of the Geocadabra Construction Box,...

Theoretical Frameworks and School Context

Sack, Jacqueline; Vazquez, Irma

Pages: 5 –11

[The rationale and Spatial Operational Capacity theoretical framework that support the project are described along with the design research methodology that evolved over the 7 years of research, the school context, and a pre-interview used to support the researchers’ perspectives on each...

Introductory Activities

Sack, Jacqueline; Vazquez, Irma

Pages: 13 –18

[The trajectory’s introductory activities developed children’s abilities to coordinate 3D models with 2D conventional pictures as shown in the adapted SOC model (Fig. 2.2). These included building four block “houses” using appropriate positional language; the set of Soma figures (made from 3 or 4...

The Geocadabra Construction Box Dynamic Geometry Interface

Sack, Jacqueline; Vazquez, Irma

Pages: 19 –27

[The children learned to use the Geocadabra Construction Box by constructing virtual cube structures to match the conventional 2D figures in the printed Build and Explore with Geocadabra manual. The process builds proficiency with top-plan numeric views. As they progressed, they were able to...

3D to 2D via Top-View Plans

Sack, Jacqueline; Vazquez, Irma

Pages: 29 –36

[Having become proficient at correlating 2D pictures with top plan numeric view representations learners used the Construction Box to create their own task card puzzles for peers to solve without the aid of the digital interface. These included 2D pictures of Soma assemblies and later, top plan...

Connections to Numeracy

Sack, Jacqueline; Vazquez, Irma

Pages: 37 –44

[Volume of rectangular prisms extended into an interesting scaling problem: One child asked if they could try to build a Soma cube as large as the teacher’s demonstration Soma cube (made with very large individual cubes) using the smaller Soma figures. Initially they built four Soma cubes using...
