Learning Objectives

Indicator: 2.3.2.LI.5 - Discuss Ceilings

By the end of the lesson, learners can:

Define a ceiling and explain its position within the superstructure of a building, distinguishing it from other superstructure components such as walls, floors, and roofs.
Identify and describe at least four different materials used for ceiling construction, including their characteristics and common uses in Ghanaian buildings.
Explain at least five functions of a ceiling in a building, relating each function to the comfort, safety, or durability of the building and its occupants.
Compare and contrast different ceiling types in terms of cost, durability, appearance, and maintenance, and justify a suitable ceiling choice for a given building scenario.
Work collaboratively in mixed-ability groups to present findings on ceiling materials and functions, demonstrating respect for diverse opinions and ensuring all group members contribute meaningfully.

Curriculum details

Strand: Building Construction Technology (Strand 3)
Sub-strand: Substructure and Superstructure (3.2)
Content standard: 2.3.2.CS.2 - 2.3.2.CS.2 Demonstrate knowledge and understanding of Load bearing and non-Load bearing components of the superstructure. 2.3.2.LO.1 Categorize and describe foundations used under various soil conditions. 2.3.2.LO.1 Be able to differentiate Load bearing from non-load bearing components and their functions in the Super structure.
Indicator: 2.3.2.LI.5 - Discuss Ceilings
Suggested placement: Semester 1, Week 20 (Week 20 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

Communication: In a whole class ask learners to explain ceilings as building components of the Superstructure.
Collaboration:
- In mixed-ability groups ask learners to outline materials used for putting in place ceilings. This method is to enhance effective participation in teaching and learning by different learners including the Approaching Proficiency, Proficiency and Highly Proficient.
- (Identification of ability of learners and positioning to ensure mixed ability).
- In structured groups (GESI) ask learners to discuss the functions of a ceiling as a component of the Superstructure.

Assessment (2.3.2.AS.5). The document marks these depth-of-knowledge levels for this indicator: Level 2 Skills of conceptual understanding; Level 3 Strategic reasoning.

Teaching and Learning Materials:
- Use of Simulation; Virtual to illustrate setting out.
- Use of Flip Chat to illustrate excavations.
- Use of Simulation, Virtual and Typical foundational works as seen in progress at different Construction sites to discuss various types of foundations given the soil type.
- The use of Simulation; (virtual) to illustrate types of load-bearing and non-load bearing members of the superstructure.
- The use of Superstructure works as observed at different Construction sites to illustrate the use of load and non-load bearing members.
- The use of flip-charts to illustrate types and functions of load-bearing and non- load bearing members of the Superstructure.
