Mr. Jarski taught 2nd and 5th grade at Rocky Run Elementary in Stafford County before coming to Hampton Oaks Elementary.

Mr. Jarski earned his Bachelor of Science in Education from Kutztown University in Pennsylvania, a Masters of Education in Curriculum and Instruction with a focus on Technology Leadership, and a Masters in Educational Leadership both from George Mason University.

Mr. Jarski is a strong believer in the constructivist approach to teaching. Constructivist teaching is based on the belief that learning occurs as learners are actively involved in a process of meaning and knowledge construction as opposed to passively receiving information. Learners are the makers of meaning and knowledge so should be involved in project/performance-based learning where the students are developing their understanding through inquiry and creation. He also is a proponent of Blended Learning where the students do part of their learning online and then part of their work offline. The students work on projects in the classroom to apply and show what they have learned, while the teacher remediates/extends the students based on their individual needs.
