Welcome to my website. Here you will find materials from all of my classes and many other resources to help you learn. My experience includes the teaching of many subjects: astronomy, chemistry, geology, meteorology, conceptual physics, web development and design, programming, electronics, urban gardening, food chemistry.

Education is a difficult field to belong to these days. On one hand information is easy to access. If you want to learn something new you can probably find excellent instructions via videos and other media on the Internet - so why come to a classroom? It is an important question to ask. Enrolling in college classes involves you with a community of learners. Note the word community. Please ask yourself: what does it mean to belong to a class - and to participate in a shared experience of learning?

My approach to teaching is multi-faceted. It seems to me that authentic experiences, tactile and immediate, are critical to building a connection between the learner and the subject. Certainly a love of the subject helps! Sometimes learners need structure and goals set externally to keep them moving through material. Sometimes learners need to be inspired and motivated.

Based on my years as an educator, my own intense curiosity about the world, my passion for learning and a commitment to your success I hope to provide you with an exceptional learning experience.

Mastering Chemistry is OPTIONAL. If you like doing online homework then I'm happy to set it up for you. It is also fine to do homework on paper. Mastering Chemistry Registration
Mastering Chemistry Website. If you have the 4th edition please wait to register for the online supplement. I have only set up a course for the 3rd edition.
