This article presents an empirical study of an open educational course in an online peer-to-peer university (P2PU). P2PU is a nonprofit organization offering free educational opportunities. Focus is on how peers are part of creating course content in a Web 2.0 environment. Massive open online courses (MOOCs) have evolved into two different pedagogical directions: content-based xMOOCs and connectivist cMOOCs. cMOOCs emphasizing learning in networks developed informally, where learners are part of creating course content, resemble P2PU`s vision. We investigated processes of interaction in co-creation of tasks in an open educational course and what opportunities and challenges emerge. We employed template analysis for coding data. We report two different processes of interaction between users and organizers: problem identification and co-creation of tasks. This study contributes to understanding a new model of teaching and learning through scrutinizing participation in an open educational course and explores implications for the learning experience.
The paper is a case study of customer-initiated software product development. We have observed and participated in system development activities in a commercial software house (company) over a period of two years. The company produces project-planning tools for the oil and gas industry, and relies on interaction with customers for further development of its products. Our main research question is how customers and professional developers engage in mutual development mediated by shared software tools (products and support systems). We have used interviews with developers and customers as our main source of data, and identified the activities (from use to development) where customers have contributed to development. We analyze our findings in terms of co-configuration, meta-design and modding in order to name and compare the various stages of development (adaptation, generalization, improvement request, specialization, and tailoring).
The bacterial community of fermented horse milk (koumiss) from Mongolia was studied using three methods: cultivation, direct identification by 16S rRNA clone library and denaturing gradient gel electrophoresis (DGGE). Ninety-eight strains were isolated by traditional cultivation and 61 of those were randomly selected for further identification by 16S rRNA gene sequencing. The strains were dominated by lactic acid bacteria (LAB; six different lactobacilli), Acinetobacter, Bacillus and Psychrobacter. Construction of the clone library analysis revealed that 16S sequences of 220 clones, genus Lactobacillus was dominant, but Streptococcus thermophilus, Acetobacter pasteurianus and uncultured clones were also detected. Ten unique bands were sequenced from the DGGE and revealed: Lactococcus lactis, Lactococcus lactis subsp. lactis, Clostridium acidurici, Acinetobacter johnsonii, Dickeya sp., Enterobacter sp., Pseudomonas sp., Raoultella sp., and Ruminococcus sp.. In vitro growth inhibition of three human pathogens, Escherichia coli, Enterobacter sakazakii and Staphylococcus aureus by 14 culturable bacteria displayed that only three of the isolates tested inhibit growth of E. sakazakii while most of the other bacteria delayed growth of the target bacteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
