Figure 1From: Mathematics and biology teachers’ tacit views of the knowledge required for teaching: varying relationships between CK and PCKAnalysis of a mathematics teacher’s data (Teacher M11) using a repertory grid tree diagram. (1) Elements: (A) a group of elements with high coherence; (B) another group of elements with high coherence; (2) Coherence rate between the elements in group B; (3) and (4) Groups of PCK elements; (5) CK element; (6) Coherence rate between the elements in groups A and B; (7) Constructs; (8) Coherence rate between the constructs: ‘Connected to teaching mathematics’ and ‘Not connected to mathematics’; (9) Coherence rate between the elements in group A.Back to article page
