Designing online learning communities: lessons from Ekşisözlük

Lack of student participation and intrinsic motivation in online learning environments is a challenge to instructional design. There are some online communities which overcome this challenge by attracting participants from diverse backgrounds to engage, learn, and share information within their context.
Ekşisözlük, an online collaborative dictionary, is one of these communities. In this study we inquire for the unique characteristics of Ekşisözlük that can be applied to online learning environments to increase student motivation and participation. Study data were collected through online surveys and one-to-one interviews.
Study findings show that the unique characteristics of Ekşisözlük include a community history, individual identities evolved through participation, an effective search facility, and representation of multiple perspectives. In the implications for practice section, we discuss the identified characteristics and address some strategies to implement them in learning environments.

Data management for prospective research studies using SAS® software

Maintaining data quality and integrity is important for research studies involving prospective data collection. Data must be entered, erroneous or missing data must be identified and corrected if possible, and an audit trail created.

Using as an example a large prospective study, the Missouri Lower Respiratory Infection (LRI) Project, we present an approach to data management predominantly using SAS software. The Missouri LRI Project was a prospective cohort study of nursing home residents who developed an LRI. Subjects were enrolled, data collected, and follow-ups occurred for over three years. Data were collected on twenty different forms. Forms were inspected visually and sent off-site for data entry. SAS software was used to read the entered data files, check for potential errors, apply corrections to data sets, and combine batches into analytic data sets. The data management procedures are described.

Study data collection resulted in over 20,000 completed forms. Data management was successful, resulting in clean, internally consistent data sets for analysis. The amount of time required for data management was substantially underestimated.

Data management for prospective studies should be planned well in advance of data collection. An ongoing process with data entered and checked as they become available allows timely recovery of errors and missing data.

The Dictatorship of the problem: choosing research methods

It is relatively easy to investigate how to employ a particular research method in the social sciences. It is considerably more difficult to decide which to use. Which method to use is arguably a more important question than how to use that method. ‘Which method?’ is, at least, the necessarily prior question. One cannot look up how to do something until one has decided what that something is. Methodological innovation depends directly on methodological choice. Researchers continuing a tradition, or working within a paradigm can often avoid making difficult methodological choices. Researchers seeking to innovate cannot. The question ‘which method?’ is particularly important for selecting research designs, because design choice importantly shapes most of the other choices researchers make. Designs are most effective and have the greatest potential for innovation when they are dictated by the nature of the research problem.
