According to Molnar (2014), full time virtual school education lacks a measurement tool that accurately measures effective virtual teacher practice. Using both qualitative and quantitative methods, the current study sought to understand the common practices among full time K-8 virtual school teachers, the extent to which teachers believed such practices impacted student learning, as well as the methods in which current standards, recommendations and practices were implemented in the full time K-8 virtual school setting. The relationship between virtual school teacher practices and their Technological Pedagogical and Content Knowledge (TPACK) was also explored. Using the standards, practices and recommendations developed for online learning from International Association for K-12 Online Learning (iNACOL), National Education Association (NEA), Southern Regional Education Board (SREB), and the International Society for Technology in Education (ISTE) a team of focus group members gave input on the common practices for teaching students in the full time K-8 virtual school environment. The results included 11 general virtual school teacher practices, 12 teacher practices relating to evaluation and three practices relating to special needs and diverse learners. Qualitative and quantitative findings indicated that teachers most frequently meet the established practices through the following strategies: phone conferences, live sessions with students, feedback on assessments, webmail communication, professional development, collaborating with peers/teacher collaboration, professional learning communities, curriculum based assessments on the phone, communicating with family stakeholders, and determining students in the bottom quartile. A framework for K-8 full time virtual school pedagogy which includes evaluating student learning and individualizing instruction through technology tools and collaborative methods was developed. Finally, the quantitative findings indicated that of the three virtual school teacher practice categories (teacher practice, evaluation and special needs and diverse learners), evaluation was the leading predictor of teacher TPACK scores. Specifically, collaboration, having an online voice and presence, and using data from assessments to modify instruction were found to significantly predict a teacher's Technological Pedagogical and Content Knowledge. Using virtual school teachers' expertise on the practices which most impact student learning and the methods for implementing virtual school teacher practices, the researcher created a draft full time K-8 virtual school teacher evaluation rubric.
