2.1 The Challenge of Teaching and Learning Geometry in Secondary Mathematics
Geometry occupies a distinctive and challenging position within secondary school mathematics
curricula worldwide. Unlike arithmetic or algebra, which rely primarily on numerical manipulation
and symbolic reasoning, geometry demands that learners develop spatial visualisation skills,
deductive reasoning abilities, and the capacity to mentally manipulate abstract two-dimensional and
three-dimensional figures (Battista, 2007). Learners must understand properties of shapes,
transformations, congruence, similarity, coordinate geometry, and geometric proofs—concepts that
are inherently visual and spatial but are traditionally taught through static diagrams on chalkboards
or worksheets, often supplemented by verbal explanations and memorised theorems.
For many secondary school learners, geometry presents significant difficulties that are qualitatively
different from other mathematical domains. Research consistently identifies geometry as a source of
mathematics anxiety, disengagement, and underachievement, particularly among learners who
struggle with spatial reasoning or who have specific learning disabilities affecting visual-spatial
processing (Heinze, Cheng, Ufer, Lin, & Reiss, 2008). Whereas arithmetic can be practised through
drills and algebra through procedural repetition, geometry requires learners to 'see' relationships that
are not explicitly stated. A learner may memorise the theorem that angles in a triangle sum to 180
degrees, but understanding why this is true—and being able to apply it to novel
configurations—requires visual reasoning that traditional instruction often fails to develop.
Compounding this difficulty is the static nature of traditional geometry instruction. A teacher draws a
triangle on the board, labels its angles, and explains the theorem. Learners copy the diagram into
their notebooks. But the triangle on the board does not move. The learner cannot drag a vertex to see
how the angles change in real time. They cannot test what happens if the triangle is stretched,
flattened, or rotated. This static representation, while better than no visual at all, fundamentally limits
the depth of understanding that learners can achieve (Hegedus & Moreno-Armella, 2010). Geometry,
at its core, is about relationships between moving, changing shapes—yet traditional instruction
presents these shapes as fixed and unchanging.
Furthermore, secondary school mathematics classrooms are increasingly diverse, including learners
with varying prior knowledge, different cognitive strengths and weaknesses, and a range of learning
preferences and needs. Some learners are visual-spatial thinkers who thrive on diagrams but struggle
with symbolic manipulation. Others are more comfortable with numerical or verbal reasoning but
find visualisation difficult. Many learners with specific learning disabilities (e.g., dyscalculia,
visual-spatial processing disorders) experience particular difficulty with traditional geometry
instruction. An inclusive classroom requires multiple representations of geometric concepts—visual,
verbal, symbolic, and kinaesthetic—so that each learner can access the content through their
preferred or strongest modality (Florian, 2015).
