The document summarizes two evaluation studies in educational technology, focusing on their methodologies and specific technology features. The first study explores how integrating technology impacts learner interactions in elementary classrooms, finding positive effects when aligned with constructivist teaching. The second study analyzes online discussion dynamics in an asynchronous learning environment and their correlation to student learning outcomes among graduate students.

2. In this PowerPoint presentation we are going to Summarize two evaluation studies in educational technology. The first summary focuses on the evaluation methodology used, in terms of purpose and instruments. The second focuses on the evaluation of specific technology features.

3. First Summary: Study Title: The impact of educational technology on learner interactions A multiple case study of elementary classrooms. References: Miller, K. (2007) The impact of educational technology on learner interactions A multiple case study of elementary classrooms.

4. First Summary: Introduction: The use of educational technology in schools as a means to improve student learning has received extensive attention over the past two decades . With the advent of the internet and a variety of software and hardware applications, school districts have predominantly focused on the acquisition of hardware and computer network infrastructure in the pursuit of educational technology goals!!!

5. First Summary: The Purpose: To study a selection of elementary school classrooms in order to observe, analyze, and describe the impact of incorporating educational technology (into traditional teaching practice and into lessons that were more constructivist in nature) on learner interactions . Subjects: Three separate classroom teachers in one school were selected to be observed with their students.

6. First Summary: Instruments: Four primary methods of data collection – observations, personal interviews, focus group interviews, and document review – were utilized during the research. Results: The study concluded that integrating technology can positively impact the interactions of learners in elementary classrooms when used as a tool to support constructivist pedagogy.

7. Second Summary: Study Title: Evaluating online conversation in an asynchronous learning environment: An application of Grice's cooperative principle. Reference: Ho, Chia-Huan & Swan, Karen. (2007). Evaluating online conversation in an asynchronous learning environment: An application of Grice's cooperative principle. Internet and Higher Education 3–14.

8. Second Summary: Introduction: Asynchronous communication has become the dominant delivery mode for online instruction, as it is convenient for both students and instructors to participate in class discussions at any time, from any location. Computer-mediated online discussion has long attracted the attention of researchers precisely because it is significantly different from face to- face discussion in traditional classrooms.

9. Second Summary: Purpose: To examine the actual participation and dynamics that occur in online discussions and their relationship to student learning outcomes. Subjects: An online English grammar course was the case investigated in this study. The majority of the students enrolled (A total of 15 ) were graduate students in the TESOL master's program at a public research university in upstate New York, who were required to take the class as part of their degree requirements.

10. Second Summary: Research Design: A content analysis approach was used to investigate students' socio-cognitive processes in an online graduate-level English grammar class. Student postings were rated using a newly developed Gricean Cooperative Principle scoring rubric to assess student participation as determined by four maxims: Quantity, Quality, Relevance, and Manner as shown in the next slide.
