Lesson 1: The Design Process

Introduction

The Design Process is a modern approach to the teaching of practical skills in schools, colleges and universities. It is sometimes called Product Design.

Objectives

By the end of the lesson, learners will be able to: define the Design Process. explain the framework of design. discuss the advantages and disadvantages of the design process in schools. illustrate the design process diagrammatically

The process has various stages through which the design and construction of an object is taken through. The Design Process is illustrated diagrammatically in figure 1.

Fig.1:The Design Process is a cycle which begins with Identification of problems.

Lesson Content

Definition of design

Designing is an activity which involves the use of a wide range of experiences, knowledge and skills to find the best solution to a problem within certain constraints. Designing entails identifying and clarifying problems, making thoughtful responses and then creating and testing your solution.

There are many types of design. Some of these include:

1. Graphic design involves arranging shapes, images and/or type so they convey a visual message
2. Engineering design involves using mathematics, physics, and/or chemistry to solve a problem with a product or a process
3. Landscape design involves the arrangement of natural elements: Earth, Stone, Flora, and Water so that they blend into a visually appealing and functional outdoor space

   Framework of design

   One may wonder why manufacturers have to go through the process of designing instead of manufacturing right away in the workshop. In a way, we are likely to ask the question 'should it be 'process' before 'product' or vice versa'? There are many different methods of solving a problem. A framework is a series of linked stages which will help solve a problem. It is needed to support the design work. The framework makes the design easier.

   Advantages of the Design Process

   The process has many advantages compared with the traditional method of teaching practical skills. Some of these are:

   • it brings out (unearths) the creative potential of the learner.
   • It suppresses the spirit of copying in class.

   • It is student-centred as learners play active role in planning the practical lesson and skills.
   • It relates learners' learning outcomes to real life situations.
   • It imbibes the spirit of researching in students.
   • It encourages learners to become aware of the problems around them.

   Now let's look at some of the disadvantages of the Design Process.

   Disadvantages of the design process

   • It is time consuming to go through the lengthy process before the realisation.
   • It is less economical since one requires stationery and quite a lot of materials to present the various stages.
   • Without artistic skill, one may get downcast with the inability to sketch or draw effectively hence discouraging further attempt.
