Our Initial Goal
• To Understand the Standard Model
• To Investigate the Rationale
• To Determine if the Standard Model could
be taught in three lessons.
• Content
• Lessons
• To Briefly Explain Further Developments
The Rationale
Session 1: Why Teach the Standard Model / Particle
Physics?
The group discussed possible arguments against
the inclusion of particle physics in teaching
programs, then examined counterarguments,
before coming up with the following consolidated
list of Reasons for Teaching about the Standard
Model.
Reasons for Teaching about the
Standard Model
• 1. Curiosity is a natural human characteristic.
People have always been particularly interested to
learn about their origins and the origins of their
world. The Standard Model is the best explanation
we have of the origins of the universe, and
students have right to know about it.
• 2. The story of the historical development of the
Standard Model gives an excellent picture of the
way science works, as a developmental process
and an example of the co-operative nature of
scientific development.
• 3. The Standard Model can be introduced to students in a
descriptive fashion and provide a good understanding. But
can be further developed mathematically, for those who
wish to progress to higher levels. Thus the subject is
accessible to students of all levels of ability and with
various preferred learning styles.
• 4. Particle Physics (along with the linked topic of
Astrophysics) is at the forefront of modern developments
in science. Including this topic will give students an
appreciation of the fact that physics is an ongoing area of
development, harness their natural interest in these subjects
and provide skills and knowledge for an unknown future,
as well as contributing to the level of scientific
understanding within society.
• 5. Resources are being developed to
facilitate the inclusion of such programs,
and their presentation in the classroom and
laboratory.

Three Lessons
Level-General High School Physics Students
Lesson One-Historical Development
Lesson Two-Particles and the Standard Model
Lesson Three-Interactions
Activities-Bubble Pictures, Particle Forming,
Feynman Diagrams
How We Worked
• We Divided into four Subgroups
• One for each lesson and one for activities.
What We Accomplished
• Gained a greater understanding for SM
• Developed a Rationale for teaching SM
• Developed three lessons for teaching SM on
a level that is suitable for all high school
students.
What we discovered
• To teach the weak interaction a fourth lesson is
required.
• To discuss future developments a fifth lesson
might be necessary.
• Some found previous HST resources helpful, but
not directly applicable to these lessons.
• We should have spent more time reviewing ideas
at an earlier stage.
• Teachers need to be educated on SM
Discoveries (cont.)

The SM can be taught with simple math.

Disclaimer
• Remember the intended audience and time
constraint for the lessons.
• Lessons are simplified and some major principles
are omitted.
• Overall Goal: To give students, regardless of
ability, a basic understanding of the standard
model.
• The inclusion of some material and how it is to be
delivered is left open to the discretion of the
teacher.
