Teaching mathematics for life skills and for the examination: Possibilities for reconciliation
David MtetwaDepartment of Science and Mathematics
Education, University of Zimbabwe
Some contextual observations
Curricula docs emphasize thrust on teaching and learning for life skills and mental capabilities [developmental orientation]
Classroom instructional action focuses on exam [reward system]
Student learning action focuses on the exam [currency] Parental reaction is centred on the exam [accountability] Employer fraternity appear to require both [evidence] Researchers: rhetoric on life skills, pragmatic on exam
[academic game]
Purpose
Draw attention to an apparent tension [exam – life skills] Put on the table some issues related to the
tension Encourage reflection on it while exploring
possibilities for resolving tension Develop common practitioner understanding Raise fresh questions
Some issues and implications
Validity/reliability of exams Same exam produces an A student who struggles
and one who does not: questioning Zimsec ?? Zimsec exam an omnibus instrument (serves
multiple purposes, one size fits all [placement, certification, aptitude, achievement]
No single common but different validitiesTeacher tests focus on predicting Zimsec exam
Practicality considerationsTeaching for life skills requires too much time and
resources Often teachers deal with pupils (uninterested); not
scholars (motivated) Equal opportunity aim (ability range too wide) Assessing for deep understanding costly (time,
resources, expertise) Special capabilities on the teacher are assumed
(yet often lack)
Searching for middle ground: A proposal
Acknowledge ruling constraints (time, resources, work & learn environment, special teacher capacities that may lack)
Aim for attaining both teaching objectives (exam and life skills)Notion of preparation and incubation [Poincare &
Hadamard in Tall] Notion of gestalt [Gestalt Psychologists] [Kohler] Notion of PCK [Shulman]

Linking theory, phase, activity
Invest in preparation and incubation (introducing phase) appreciating motivation for the mathematical objects
being introduced [interest]reflecting on qualitative description of the objects [local
meaning]Focus on development of main principle and language
(gestalt) [elaborating phase] investigate and describe properties of objects formulate definitions of objects and explore implications
[formal theory]
Frame and administer detail filling mathematical tasks [concluding phase] (PCK an asset) engage in problem-solving around the definitions
and their implications (meaningful rather than drill practice) [consolidating understanding, proficiency]
reflect on objects again and attempt to appreciate their place in the topic and the subject (overview, global big-picture meaning)
Remarks Many teachers invest more in the 3rd phase and far less in the first
2 phases; or begin by stating definitions Many begin and end with the 3rd phase, typically called exercises
or practice (largely routine and computational; little strategic thinking)
Practice, if done in class, is usually ‘busy work’, and if at home it is for ‘accountability’
If practice involves problem solving at all, it is usually the type involving recognition and recalling only, little productive thinking
The key to reconciliation between teaching for exam and for life skills lies in the idea of preparation-incubation, gestalt, and PCK
Lesson structure: 3 phases
Genesis of Object(recognition or creation)
Exploring characteristics (operational bevaviour)
Developing object(structure and applications)
An example of lesson flow on vectors
Genesis of a vector Consider encounters with phenomena (from
maths/everyday life) requiring consideration of a new idea/object
Focus on the agency and explaining power of the idea/object (may still be nameless)
Make need for such an idea/object compelling and apparent
Examine defining characteristics (when orientation and amount of movement are important) searching for hidden treasure striker pulling a shot boxer throwing a punch disease carrier in an epidemic locating a point relative to another on a plane/space
focus on consequences of missing one or both parameters
Developing idea/object combination of the 2 qualities important,
deserves a name [vector]needs representation (conventions and contexts
of use: geometrical, algebraic, other?) mathematical properties (intuitive) [geometrical –
practical meaningfulness; algebraic – consistency with other familiar algebraic objects and operations, other?]
formal definition formulation [existence/creation issue]; meaning to be established before definition
implications [theoretical, e.g., theorems, and generation of other objects such as momentum, vector spaces, etc]
implications [applications, e.g., as tools for problem solving as in engineering, aviation, etc.]
