GTLE Subject Specialism Physics case studies
GTLE Subject Specialism Physics · Put your knowledge to work in context.
The GTLE Subject Specialism Physics paper is the physics-specific component of Ghana's teacher licensure assessment, taken by candidates who intend to teach physics in Ghanaian schools and who must demonstrate both physics content mastery and the pedagogical knowledge expected of a licensed teacher. The paper spans mechanics and motion, waves, sound and optics, electricity and magnetism, thermal physics and kinetic theory, modern and nuclear physics, measurement and practical laboratory skills, curriculum and instructional planning, assessment and misconception diagnosis, and mathematical and graphical reasoning. The GTLE Subject Specialism Physics case studies are 5 cases and about 2,953 words.
1Projectile Range from a Bench Edge: When 45° Is Not the Maximum
In a Grade 11 mechanics practical, groups use a spring-loaded launcher fixed to a bench edge 0.90 m above the floor. The launcher gives a ball an initial speed of 4.2 m/s at selected angles to the horizontal.

During a required practical on electrical characteristics, students use a 12 V supply, a 12 V 24 W filament lamp, a 100 Ω resistor, an ammeter and a voltmeter. Group A records for the lamp: (1.0 V, 0.30 A), (2.0 V, 0.55 A), (4.0 V, 0.95 A), (6.0 V, 1.30 A), (8.0 V, 1.60 A), (10.0 V, 1.85 A), (12.0 V, 2.00 A).
