At the end of teaching via the lecture method, the teacher allows at least students from any of two groups to ask a review questions each which the teacher writes on the board, for example: ―Explain the meaning of X and Y on the PPC.‖

STEP V Each group representative stands up to air the group submission

STEP VI. Teacher points out differences among each group‘s solutions proffered, and then makes summary and rounds off the lessons.

Lesson two: 40 Minutes

Please note that the main activity of each student within each group is just to actively listen and make jottings and not to bend down for a lengthy as the teacher lectures during this lesson.

i. The Teacher explains the relationship between PPC and Opportunity Cost. PPC slopes downwards from left to right which is direct consequence of the existence of Opportunity Cost.

ii. The basic problems of Economics, mainly scarcity. And the need to make choices, are best illustrated with a PPC.

iii. The society has to choose what to produce and had to start producing them.

ACTIVE REVIEW SESSIONS ON LESSON TWO

At the end of teaching via the lecture method, the teacher allows students from any of two groups to ask a review questions each which the teacher writes on the board, for example ―What steps can be taken to address underutilisation of resources‖?

iv Each group representative stands up to air the group submission

v Teacher points out differences among each group solutions proffered, then makes summary and rounds off the lessons.

Lesson Three: 40 Minutes: Active Review Activities

i. During this last period for the week, students are seated according to their groups of five for active review.

88

ii. The teacher writes review questions on the board, .e.g. a combination of the mini review made at the end of the first two periods. e.g. Explain the meaning of X and Y on the PPC and what steps can be taken to address underutilisation of resources? The teacher asks each group to provide answers to the question.

iii. Students are made to work together for solutions. Each group shows its solutions to the whole group.

iv. Differences among the solutions are pointed out by the students.

v. The teacher rounds off the lesson.

NB. Please note that during active review session at the end of the first and second lesson, it is the teacher that identifies the differences among the solutions given by the students while the students identify these differences during the main active review session slated for lesson three.

Active Review Instructional Plan (ARIP) (Active Review Group)

Week 2: Module A

Class: SSS2 Economics

Topic: Concepts of total average and marginal Productivity Duration: 2 hours for the week at 40 minutes per period.

Instructional Materials: Charts and textbooks

Fundamental of Economics for SSS, African Ltd, Ibadan.

Previous Knowledge: Students had already received tuition on other concepts like labour force, efficacy of labour, etc.

Objectives: At the end of the lesson, students should be able to define:

i. Total average and marginal Productivity

ii. Calculate the Total, Average and Marginal Productivity iii State the law of diminishing returns

iv Present the function in diagram form Presentation: Lesson one (40 Minutes)

Step 1. Students adjust sitting arrangement to reflect existing active review groupings.

89

Step II. Teacher presents concepts of total average and marginal Productivity.

Step III. Definition:

i. Total output is the quantity of output obtained from the use of a given unit of labour.

ii. Average output: is the output pen unit of labour

A.P = T.P

Unit of Labour

Marginal productivity is the charge in total product when variables factor (labour) is increased by one unit.

One unit

MP = TP

In unit of labour

ACTIVE REVIEW SESSIONS ONE LESSON ONE

Step iv: At the end of teaching via the lecture method, the Teacher allows at least students from any of two groups to ask a review questions each which the teacher writes on the board, for example Explain the concept of total average and marginal productivity

v Each group representative stands up to air the group submission

vi Teacher points out differences among each group solutions proffered, then makes summary and rounds off the lessons.

Lesson Two: 40minutes Step 1

Teacher explains that the Law of Diminishing Returns states that, under a given technology, an increase on the variable factor, with other factors fixed, will increase total output but after a certain point the extra output resulting from unit increase in their variable input will decrease

90 Step 2 Teacher makes: Illustration with table

no of employed TP AP MP

1 5 5 -

2 20 10 15

3 45 15 25

4 60 15 15

5 60 12 0

6 54 9 -6

7 42 6 -12

Teacher makes explanation from the above example (Table)

i. Increase in returns occurred when the second and third labour were employed. At these stages TP, AP and MP were on increase

ii. Constant returns occurred at the 4^th and 5^th stages. At these stages, the TP remained at 60, zero MP and AP decreased as labour increased.

iii. Diminishing returns occurred at 5^th 6^th and 7^th labour employed. At these stages TP, AP and MP decreased as labour increased.

ACTIVE REVIEW SESSION ON LESSON 2

iv At the end of teaching via the lecture method, the teacher allows at least students from any of two groups to ask a review questions each which the teacher writes on the board, for example: ―Explain the law of diminishing returns.‖

Lesson Three 40 minutes: Active Review Activities

i. During this last period for the week, students are seated according to their groups for active review.

ii. The teacher writes review questions on the board E.g., Explain the concept of total average and marginal productivity and the law of dimishing rerturns. Teacher asks each group to provide answer to the question.

91

iii. Students are made to work together for solutions. Each group shows its solutions to the whole group.

iv. Differences among the solutions are pointed out by the students.

v. Teacher rounds off the lesson.
