Final answer:
The statement 'It discourages confidence in performance' is NOT true about the skill theme approach in physical education because this approach actually aims to boost students' confidence through skill development.
Step-by-step explanation:
The statement that is NOT true concerning the use of the skill theme approach in teaching physical education is 'It discourages confidence in performance.'
The skill theme approach is actually designed to enhance students' confidence as they develop and refine various movement skills. By focusing on fundamental themes, the approach facilitates a learning environment where students can practice basic skills, discover new strategies, and express creativity, all of which promote self-assurance in their abilities. It is a student-centered method that helps individualize learning and encourages growth in skill proficiency and confidence.
So, concerning the reference options, the correct answer would be 'b. the task is easy' since the skill theme approach promotes learning in an engaging manner, which may make tasks easier ultimately, but individual performance can indeed be evaluated.
