Dale Jensnen
After graduating from the University of Oregon with degrees in Biology and Chemistry, Dale taught Chemistry and Physics in Oregon at North Medford High School for 33 years. During this time, he wrote educational software for the Apple computer; had his own company, Chip-n-Dale Software; earned a fellowship position with Project Seraphim to write educational software for general Chemistry; coached tennis; and became an AP Chemistry Reader and consultant for the College Board.
During the height of the Apple II popularity, Dale had five programs that he marketed through his company and two programs available through the American Chemical Society.
During his 30 years of coaching, Dale's teams captured two State Championships, he was a three-time recipient of Oregon's Tennis Coach of the Year, he twice won the Regional Tennis Coach of the Year, and in the 90's, his team won 65 straight dual matches.
For the past twenty-five plus years, Dale has been active as an AP Chemistry Exam Reader, Table Leader, and Question Leader. He has worked as a consultant for the College Board conducting weekend and week-long workshops. In 2007, Dale was appointed and served on the SAT Test Development Committee. Although he started as an AP Chemistry consultant, he soon became more involved in conducting various other workshops for the College Board and the National Math and Science Institute (NMSI). Presently, he is certified to present AP Chemistry, the new Pre-AP Science courses, and NMSI AP Chemistry Student Study Sessions.
When he retired from North Medford, Dale was approached by Syracuse High School in Utah to come in for one year and revamp the Chemistry curriculum. In one year, the school saw a 25% increase in their end of course exam.
While moving back to Oregon, he was invited to teach for St. Mary’s High School. Being at a small private school provides a lot of opportunities. Dale has taught Anatomy/Physiology, First year Chemistry, AP Chemistry, AP Physics 1, and AP Physics C – Mechanics.

COURSE DESCRIPTION
1/3 Direct Instruction + 1/3 Group Work + 1/3 Individual Instruction
I have contracted with my school to use my Chemistry Lab. I will be conducting the labs and allowing you to gather data. I will be demonstrating how you can have a successful online lab course. The Science companies are working with me to provide laboratory kits, eBooks, probeware, and video resources.
I know we are going through some hard times. Being separated from our students and fellow colleagues has been difficult. I believe that we can use this situation to strengthen our craft by making us create new ways to teach our subject.
This summer there will be a new focus for almost all of the current AP courses.
These changes will include:
Beyond explaining the changes, we will look at the content, labs and activities that may be used to enhance your course. These are a few of the topics, labs and activities that we will examine:

- Changes to the Chemistry Curriculum Guide
- changes to the required labs
- changes to the Learning Objectives
- replacing the Big Ideas with Units
- going to a theme-based approach
- new resources to help you and your students
- changes to the Science Practices
- why the LO’s related to the 16 labs have been removed.
- many LO’s have been reworded or blended with others
- textbooks
- and …
