A Comparison of Experimental and Observational Approaches to Assessing the Effects of Time Constraints in a Medical Licensing Examination

Test administrators are appropriately concerned about the potential for time constraints to impact the validity of score interpretations; psychometric efforts to evaluate the impact of speededness date back more than half a century. The widespread move to computerized test delivery has led to the development of new approaches to evaluating how examinees use testing time and to new metrics designed to provide evidence about the extent to which time limits impact performance. Much of the existing research is based on these types of observational metrics; relatively few studies use randomized experiments to evaluate the impact time limits on scores. Of those studies that do report on randomized experiments, none directly compare the experimental results to evidence from observational metrics to evaluate the extent to which these metrics are able to sensitively identify conditions in which time constraints actually impact scores. The present study provides such evidence based on data from a medical licensing examination. The results indicate that these observational metrics are useful but provide an imprecise evaluation of the impact of time constraints on test performance.     

The use of digital storytelling in elementary Math teachers’ education

Technological devices are widely used in various forms and for various purposes with educational systems. Teachers are required to not only use technology with the utmost efficiency, but to also act as role models for students in terms of appropriate use of technology. However, many teacher candidates are not aware of the educational use of technology classroom; hence, technology must be especially integrated into undergraduate teacher training programs through courses and field experience. Various methods, techniques, tools, and equipment are utilized in order to improve the efficiency of teaching and learning processes in the classroom, of which digital storytelling is one of them. The use of digital stories in education is beneficial both for teachers and students. For this reason, this research investigates the use of digital stories in mathematics education as well as the opinions and experiences of mathematics teacher candidates about creating, using, and evaluating digital stories. Data of the study were collected via semistructured interviews, transcribed, and content analyzed. The results of the study showed that prospective math teachers preferred GoAnimate program to create digital stories due to its ease of use, design, and the characters and visuals it suggests. Furthermore, the prospective teachers were found to aspire to use digital stories in their future careers.     

Perceived social support,quality of life and satisfaction with life in elderly people

The aim of this study examines the relationship between quality of life, satisfaction with life and multidimensional perceived social support in people aged 65 years and older. The implementation part of the study was carried out with elderly people living in the city center of Burdur, Turkey. Data were collected in March 2018 from 517 participants and then assessed. The results of the analyses revealed that perceived social support explained 11.7% of the total variance in the satisfaction with life, 22.1% of the total variance in the quality of life. In addition to, the perceived social support and the quality of life explained 28.6% of the total variance in the satisfaction with life. And the quality of life was the most influential variable on the satisfaction with life. The findings of this study suggest that making improvements to the elderly people social support and quality of life will increase their satisfaction with life.     

A Clearer Vision: Creating and Evolving a Model to Support the Development of Science Teacher Leaders

This paper describes a professional development model for developing science teacher leaders that has evolved and been refined through working with 16 high school chemistry and physics teachers in high-needs schools over the past 3 years. The theoretical framework draws upon Goodwin’s notion of professional vision and Dempsey’s four metaphors to inform an understanding of professional identity consistent with innovation and empowerment in (a) the classroom setting with students and (b) with teachers in collegial environments. Thus, leadership practices and purposes are discussed at two distinct levels and contexts, which interact reflexively. Sociolinguistic discourse analysis of multiple data sources enabled us to identify the professional development features that promoted or hindered the teachers’ growth toward a leadership perspective and disposition. Implications for science teacher renewal and retention as well as limitations of the study and proposed leadership model are also shared and discussed.

Educational technology research trends in Turkey from a critical perspective: An analysis of postgraduate theses

The aim of this study is to explore the research trends in the context of postgraduate programmes in the field of Educational Technology (ET) in Turkey between 1996 and 2016, and to uncover the possible factors that influence these trends from the perspective of ET faculty members. This study was informed by critical theory and employed the critical inquiry method. In the first phase, content analysis technique was used in order to explore trends in research methods and topics in theses completed in ET postgraduate programmes in Turkey. In the second phase, in-depth interviews were conducted with 11 faculty members regarding the possible influential factors. The findings of the content analysis indicated that ET research was dominated by quantitative research designs in the examined theses. Critical methods were overlooked and social, cultural, and political issues were largely silenced. The findings of the interviews showed that the factors that have been influential on ET research trends were the social impact of the research, personal interests and skills, disciplinary and departmental culture, and feasibility concerns. This study presents implications for better ET research by addressing blind spots of the field and providing suggestions for ET postgraduate students, ET scholars, policymakers and practitioners in a global context and other developing countries since the resulting trends in Turkey were found similar to international trends in the field.     

The relationship between Turkish pre-service ICT teachers’ educational philosophies and occupational anxieties

This study examines Turkish pre-service Information and Communication Technologies teachers’ educational philosophies and occupational anxieties. A total of 800 pre-service teachers participated in the study. Results showed that the predominant educational philosophies among the participants were the existentialism, progressivism, reconstructionism, and perennialism, respectively. Essentialism was the least preferred educational philosophy. In addition, the majority of pre-service teachers expressed a strong belief in both existentialism (95.6%) and progressivism (95.5%). The participants reported low levels of occupational anxiety. Pearson correlations showed very weak or no relationship between the educational philosophies and occupational anxieties. Implications are discussed.     

Utilization of biological variation data in the interpretation of laboratory test results – survey about clinicians’ opinion and knowledge

IntroductionTo interpret test results correctly, understanding of the variations that affect test results is essential. The aim of this study is: 1) to evaluate the clinicians’ knowledge and opinion concerning biological variation (BV), and 2) to investigate if clinicians use BV in the interpretation of test results.Materials and methodsThis study uses a questionnaire comprising open-ended and close-ended questions. Questions were selected from the real-life numerical examples of interpretation of test results, the knowledge about main sources of variations in laboratories and the opinion of clinicians on BV. A total of 399 clinicians were interviewed, and the answers were evaluated using a scoring system ranked from A (clinician has the highest level of knowledge and the ability of using BV data) to D (clinician has no knowledge about variations in laboratory). The results were presented as number (N) and percentage (%).ResultsAltogether, 60.4% of clinicians have knowledge of pre-analytical and analytical variations; but only 3.5% of them have knowledge related to BV. The number of clinicians using BV data or reference change value (RCV) to interpret measurements results was zero, while 79.4% of clinicians accepted that the difference between two measurements results located within the reference interval may be significant.ConclusionsClinicians do not use BV data or tools derived from BV such as RCV to interpret test results. It is recommended that BV should be included in the medical school curriculum, and clinicians should be encouraged to use BV data for safe and valid interpretation of test results.
