SHS1 Biomedical Science · Semester 2 Week 3: Diagnostic Device

Lesson notes

Learning Objectives

Indicator: 1.3.1.LI.2 - Compare and contrast primitive diagnostic medical interventions and modern diagnostic devices.

By the end of the lesson, learners can:

Describe at least four primitive diagnostic medical interventions and explain how each one was used to detect illness.
Identify at least four modern diagnostic devices and state the condition or disease each one is used to detect.
Compare primitive and modern diagnostic interventions by constructing a table that shows their similarities and differences.
Create a flow chart showing the stages of advancement from a chosen primitive diagnostic method to its modern equivalent.
Justify, with reasons, why modern diagnostic devices are generally more reliable than primitive methods, while recognising what primitive methods still offered.
