Over the past decade online learning initiatives have shown tremendous potential for broadening educational opportunities and for addressing local and regional shortages of highly qualified K–12 teachers. The Louisiana Algebra I Online initiative represents one type of online model than can address both the need for improving course offerings and for addressing teacher shortages. The goal of the model is to improve educational opportunities for students by providing them with a high-quality, standardsbased curriculum delivered online by a certified mathematics teacher and to support the professional development of teachers in hard-to-staff schools by partnering them with a highly qualified teachermentor who is available online. The innovation of this model for online learning is that it integrates classroom-based learning with virtual learning thereby providing students with the structure and opportunities afforded by regular class meetings and supports the professional development of uncertified teachers through ongoing and embedded professional development opportunities. This research suggests that the Louisiana Algebra I Online model is a viable online model for providing teachers with an effective model for authentic and embedded professional development that is relevant to their classroom experiences.

This thesis is dedicated to my wife Gail and my children, Mark and Lauren. They have watched me spend endless hours at the computer instead of with them. They have shared in my journey and always helped me when the road was hard. They have sacrificed as much, if not more, than I have. I hope this work justifies their support. ii This study examines the ability of online distance education courses using CMC and constructivist assessment tools to support cognitive presence and deep learning. Four online focus groups were conducted, three among graduate students and one among instructors who have respectively taken and delivered online courses in the Master of Distance Education program at Athabasca University. Transcripts of the focus groups were analyzed with the objective of developing a grounded conceptual model. The learning experiences, as described by the participants themselves, have shown that deep learning and

This study sought to examine instructor immediacy and presence in an online learning environment in relation to student affective learning, cognition, and motivation. It found a statistically significant positive relationship between instructor immediacy and presence. It also found that the linear combination of instructor immediacy and presence is a statistically significant predictor of student affective learning, cognition, and motivation. However, it did not find instructor immediacy to be a significant individual predictor of the aforementioned variables, whereas it did find instructor presence to be a significant individual predictor. The study also showed that students in synchronous online courses reported significantly higher instructor immediacy and presence. Implications for researchers and practitioners of online instruction are discussed at the conclusion of the paper.

A growing amount of research focuses on learning in group settings and more specifically on learning in computersupported collaborative learning (CSCL) settings. Studies on western students indicate that online collaboration enhances student learning achievement; however, few empirical studies have examined student satisfaction, performance, and knowledge construction through online collaboration from a cross-cultural perspective. This study examines satisfaction, performance, and knowledge construction via online group discussions of students in two different cultural contexts. Students were both first-year university students majoring in educational sciences at a Flemish university and a Chinese university. Differences and similarities of the two groups of students with regard to satisfaction, learning process, and achievement were analyzed.
