The purpose of this study is to examine and describe student and instructor experiences and perceptions of course design, and identify the critical issues regarding the use of a blended learning environment. A design based research (DBR) framework with qualitative approaches was carried out by collecting data from an undergraduate course offered to sophomores. The primary approach was phenomenology using the lens of heuristic inquiry. Interviews, questionnaires, documents, observation notes, instructor diary, and weekly reflection reports were the main data sources. Data were collected in three periods: preliminary study, pilot study, and actual implementation. The results of instructor experiences revealed that instructor considerations for the analysis period centered on needs and context. The design and development considerations centered v on pedagogical approach, course materials and documents, course organization, interaction, and instructor-student roles. The enablers (benefits and opportunities) of the implementation period included arousing student interest and participation potentially more, having flexibility, saving time, tracking student progress more easily, and increased interaction, collaboration, and communication opportunities. The barriers (challenges and limitations) were increased workload, difficulties related to the course and time management, overlaps, and creating harmony among F2F and online environments. The students mentioned interaction and communication opportunities, increased motivation, opportunity to voice opinions, and reinforcement of learning as enablers of the blended learning environment. The barriers were increased workload, cultural and technical barriers and dependability of environments. The critical issues were found to be context, pedagogical framework, instructor competency, and technical issues. It can be concluded that use of blended learning environments can be regarded as a paramount initiative for the higher education institutions by maximizing the enablers of both environments but also has its unique barriers to consider. The results also implied that it is the decisions on the instructional design approaches for creating balance in the course activities that is critical to blended learning environment designs.

The purpose of this study was to describe and explore the nature and frequency of the interaction and the factors affecting interaction in language classrooms. This qualitative study was conducted in a private language course in Ankara, Turkey. The sample consisted of 6 teachers. The data were collected through video-camera, semi-structred interview and demographic information log. To tackle the complexity of the raw data, data were first subjected to constant comparison analysis. Second, all results were t...
A case study on the aspects of classroom discourse in a fifth grade mathematics class in a regional elementary boarding school
Şahin, Şule; Işıksal Bostan, Mine; Department of Elementary Science and Mathematics Education (2009)
The purpose of this study was to analyze and interpret specific aspects and characteristics of classroom discourse of an elementary mathematics classroom. To examine the classroom discourse, a fifth grade mathematics classroom was observed during sixteen weeks, and twenty lessons in total. The analysis was based on two main categories: (1) Student Learning and (2) Teacher Moves. Student Learning further divided into two sub-categories as content and learning. Additionally, Teacher Moves also divided into co...
