Robert Glaser developed a psychological model of teaching that includes four major sequences: instructional objectives, entry behavior, instructional procedures, and performance assessment.

His model emphasizes systematic instruction and the alignment of teaching methods with learning outcomes.

Explanation

Oil and petrol form a thin layer on the water surface, blocking sunlight from reaching underwater plants.

This layer also restricts the mixing of oxygen from the air into the water, harming aquatic life.

Explanation

An adjective phrase modifies a noun and consists of an adjective along with its modifiers.

In "She had remarkably bright eyes," the phrase "remarkably bright" modifies the noun "eyes," making it an adjective phrase.

Explanation

Given the volume of the cube-shaped pool is 10648 m³. To find the side length (s):

s³ = 10648

s = ∛10648

s = 22

The area of the base floor = s² = 22² = 484 m²

Cost = Area × Rate

= 484 × 85

= 41140

Explanation

Non-formal education refers to organized learning outside the traditional formal education system.

It is designed to meet specific learning goals.

It can be integrated with other educational frameworks.

Explanation

حدیث نبوی صلی اللہ علیہ وسلم میں سورۃ الاخلاص کو ثلث القرآن (قرآن کا تیسرا حصہ) قرار دیا گیا ہے۔

Explanation

"After that" is used to show the step just before the final one.

It helps transition smoothly toward the conclusion (which is marked by "Finally").

Explanation

Given:

Selling price (SP) = Rs. 8413

Loss percentage = 6%

Let's denote the cost price as CP.

Since the shopkeeper loses 6%, the selling price is 94% of the cost price (100% - 6% = 94%).

SP = 0.94 × CP

8413 = 0.94 × CP

CP = 8413 / 0.94

CP = 8950

Explanation

Given:

Radius (r) = 13 cm

Distance from center to chord (d) = 5 cm

Let's draw a perpendicular from the center to the chord. This will bisect the chord.

Using the Pythagorean theorem:

r² = d² + (half chord)²

13² = 5² + (half chord)²

169 = 25 + (half chord)²

(half chord)² = 169 - 25

= 144

half chord = √144

= 12 cm

Length of chord = 2 × half chord

= 2 × 12

= 24 cm
