Criteria for evaluating an educational blog as a scientific one

  1. 1. “Criteria for evaluating an educational blog as a scientific one” 1 Vasileios Sotiroudas (Bsc, Med, IT Teacher) Antonios Lionarakis (Assistant Professor at HOU)
  2. 2. The aim… 2 This research paper explores the criteria by which an educational blog can be characterized as scientific
  3. 3. Methodology 3 A combination of quantitative and qualitative approach was used in this research work. In order to answer the research questions, a complex two-phasestrategy was followed, ensuring the maximum validity of the survey’s content
  4. 4. First Phase - Purpose 4 In the first phase, the literature review led to the development of a qualitative questionnaire which 10 experts on the field were invited to answer. The purpose of this phase was firstly to record the criteria by which they evaluate an educational blog as scientific and secondly, to check the findings of the literature review for completeness.
  5. 5. First Phase - Participants 5 The ten experts who have accepted the invitation and who returned a completed questionnaire were: 1. Professor Peter Jarvis 2. Professor Knud Illeris 3. Professor Michel Alhadeff-Jones 4. Assistant Professor Antonis Lionarakis 5. Assistant Professor Vasilios Dagdilelis 6. Assistant Professor Andreas Oikonomou 7. Researcher George Palaigeorgiou
  6. 6. First Phase - Participants 6 8. Author Nikos Dapontes 9. Special Advisor Konstantinos Kiourtsis 10. School Counselor Leonidas Katsiras
  7. 7. First Phase – Findings 7 Experts seem to give more importance to issues such as : 1. The contribution of the blog on various aspects of science (production, dissemination, monitoring and questioning of scientific knowledge) 2. The personality of the blog administrator 3. The reliability of published information 4. The democratic policy they follow regarding how to publish the post comments 5. The online community created between the blog and its readers 6. The transparency to the purposes and goals of the blog
  8. 8. Second Phase - Purpose 8 In the second phase, after synthesis and critical evaluation of the responses given by the experts, a questionnaire was prepared and posted on the internet and in which readers of educational weblogs were asked to answer the questions The purpose of this phase was to assess the criteria by which the readers themselves evaluate an educational blog as a scientific one.
  9. 9. Online Questionnaire 9 Most of the questions in the questionnaire were posed according to Likert’s hierarchy scale of 5 degrees in a table. The outcome was that a total of 26 online questions created 55 independent and dependent research variables. The independent variables of the study were sex, age, education, employment status, marital status and income. All independent variables were nominal. From the dependent variables, 48 were ​ ordinal, while 7 were nominal.
  10. 10. Analysis 10 Due to the fact that the research variables were nominal or ordinal, for every two variables (one independent with each of the dependent) was made an inspection of the nonparametric statistic test of x 2, applying as a correction the exact test of Monte Carlo in the cases where observed frequency <5. All tests were performed in a confidence interval of 95%.
  11. 11. Analysis 11 The tested cases were: H0: there is independence between the two variables H1: there is no independence between the two variables
  12. 12. Participants 12 The questionnaire was completed by 519 people over a period of 45 days which was available for online completion. In the presentation of results that follows, there are no remaining answers, since the answer to all the questions in the questionnaire was mandatory
  13. 13. Findings 13 The online questionnaire shows good level of internal reliability/consistency (a = 0.825).
  14. 14. Findings 14 Readers of educational blogs rank in order of importance the categories of evaluation criteria of an educational blog as a scientific one as follows: 1. Quality of Content 2. Transparency 3. Contribution to Scientific Knowledge 4. Design
  15. 15. Findings 15 Categories of evaluation criteria
  16. 16. Findings 16 Quality of Content
  17. 17. Findings 17 Transparency
  18. 18. Findings 18 Contribution to Scientific Knowledge
  19. 19. Findings 19 Design
  20. 20. Findings 20 In each of the above categories of evaluation criteria a host of other sub-criteria were included, the analysis of which is beyond the scope of this paper. However, the overall analysis produced the following table of evaluation criteria of an educational blog as a scientific one, in a hierarchical order.
  21. 21. Criteria for evaluating an educational blog as a scientific one 21 1. Quality of Content  clarity - understandability of information  objectivity in the presentation of issues  completeness in coverage that addresses the blog  lack of spelling and grammar errors  frequency of new content  blog posts refer on other reliable sources  accuracy of the information provided  support the blog posts with literature
  22. 22. Criteria for evaluating an educational blog as a scientific one 22 2. Transparency declaration of the purpose and the goals of the blog declaration of blog’s topics declaration of who sustains and / or finance the blog
  23. 23. Criteria for evaluating an educational blog as a scientific one 23 3. Contribution to Scientific Knowledge  they make more accessible to the public scientific works and researches  contribute to the dissemination of scientific knowledge  allow readers to judge and comment on previously published works and articles  the interaction of readers develop critical thinking that contributes to building knowledge  offer to everyone the opportunity to publish their work and put them in public review
  24. 24. Criteria for evaluating an educational blog as a scientific one 24 provide the ability to all researchers to publish their works, but without criteria  their posts should be published first in scientific journals and / or conferences  should apply peer review process for unpublished works and researches before posting them
  25. 25. Criteria for evaluating an educational blog as a scientific one 25 4. Design ability to internally search in blog posts archiving blog posts accessibility for people with disabilities the overall aesthetics of the blog (colors, background, etc.) possibility of translation into foreign languages
  26. 26. Conclusion 26 Grouping the above criteria in the category of contribution to scientific knowledge of four aspects of science, leads to the following ranking in order of importance: 1. dissemination of scientific knowledge 2. test of scientific knowledge 3. dispute of scientific knowledge 4. production of new scientific knowledge
