2. Learning Object for PDA presentation Conceptual Details about my LO Title of LOHeron’s Formula for Triangle Area Calculation Describe content of LOUsers can find out a triangle’s area by entering or changing the length of the three sides of the triangle. Potential audience:Maths teachers and Senior form students. What is purpose of LOUsers can understand the process of calculating the area using the Heron’s Formula.

3. Learning Object for PDA presentation Technical Details about my LO Size of Presentation Area320 by 240 pixels (for handheld presentation) List images and other media needed 1.Background image for the whole LO, 2.Background image for the window that the triangle is displayed, 3.A Flash object that can a)draw a triangle according to the value input from three text boxes, or from three sliders, b)Calculate the value of “s” and the area of the triangle using Heron’s Formula List types of interactions to be integrated in LO 1.Text-input: entering the lengths of the three sides of triangle 2.Sliders: a substitution input rather than the text-input

4. Learning Object for PDA presentation Users can enter the length of the triangle here Side a 5 Side b 8 Side c 12 a b c 12.5 = = 44 Sq. unit Or may scroll the bar to adjust the length The size of the triangle would change according to the length of the three sides The intermediate step and the final result will be shown instantaneously Heron’s Formula
