This study examines the reasons why authors publish in ‘predatory’ OA journals. In total, 50 journals were randomly selected from Beall's list of ‘predatory’ journals. Different methods, including WHOIS tracking, were utilized to query basic information about the selected journals, including location and registrant. Then, 300 articles were randomly selected from within selected journals in various scientific fields. Authors of the selected articles were contacted and sent survey questions to complete. A grounded theory qualitative methods approach was used for data collection and analysis. The results demonstrated that most of these journals were located in the developing world, usually Asia or Africa, even when they claimed they were in the USA or UK. Furthermore, four themes emerged after authors’ survey responses were coded, categorized, and sub‐categorized. The themes were: social identity threat, unawareness, high pressure, and lack of research proficiency. Scholars in the developing world felt that reputable Western journals might be prejudiced against them and sometimes felt more comfortable publishing in journals from the developing world. Other scholars were unaware of the reputation of the journals in which they published and would not have selected them had they known. However, some scholars said they would still have published in the same journals if their institution recognised them. The pressure to ‘publish or perish’ was another factor influencing many scholars’ decisions to publish in these fast‐turnaround journals. In some cases, researchers did not have adequate guidance and felt they lacked the knowledge of research to submit to a more reputable journal. More needs to be done by institutions and reputable journals to make researchers aware of the problem of ‘predatory’ journals. 相似文献

The purpose of this paper is to extract features from vibration signals measured from motors subjected to accelerated bearing fluting aging and to detect the effects of bearing fluting at each aging cycle of induction motors. This trending of bearing degradation is achieved by monitoring the changes in the vibration signals at various sub-band levels. This is accomplished by the application of wavelet transforms and multi-resolution analysis in order to extract information from selected frequency bands with minimum signal distortion. 相似文献

This paper provides an overview of the status of educational technology in Turkey. In the face of severe social and economic challenges, many developing nations, including Turkey, are looking to education as a potential remedy. Recognizing that in an increasingly technology-dependent world, information and communications technology skills and knowledge are critical in order to compete in the global marketplace, Turkey is firmly committed not only to improving its education system, but also to incorporating the use of educational technologies into the instructional strategy and curriculum used in schools. This is a critical initiative because, as research shows, technology-enriched educational environments can provide students with significantly expanded learning opportunities, which are linked with increased levels of academic achievement. However, like many other developing countries, Turkey is struggling to overcome a number of serious barriers to full technology integration at the classroom level, the most significant of which is non-compliance on the part of teachers. With respect to technology use in education, teachers are consistently failing to utilize technological tools for instruction purposes, for a variety of reasons. Turkey must address these reasons in order to ensure that the agenda of technology adoption into schools, an enormously expensive undertaking, does not fail. 相似文献

This study examined whether teachers prioritize the use of technology. More specifically, this paper focused on how Turkish teachers think about the importance of technology and technological tools for their daily routines. The research design employed both qualitative and quantitative methods. The data were collected through document analyses, interviews, and a survey. The results showed that the following factors lead teachers to prioritize the use of technology in the classroom: (a) globalization, (b) society’s needs, (c) technological literacy, (d) student learning, and (e) practicability. 相似文献

The effective continuing professional development (CPD) programs primarily aim to have an impact on teachers’ knowledge bases, beliefs, and views and their classroom practices, which rationally lead most of the researchers to investigate those changes on teachers primarily. Although neglected, the interrelationship between CPD programs and students is considered complex, and CPDs ultimately aim to have an impact on students’ views, too. Therefore, the purpose of this study is to survey the changes of middle school students’ views of the nature of science (NOS) by providing a large-scale CPD to their teachers and, in other words, identify the impact of CPD on ultimate beneficiaries, namely students. In this study, 10 science teachers’ data and, in the first phase, 481 and, in the second phase, 422 students’ data and the changes in their NOS views were analyzed. Results showed that the students’ and teachers’ NOS views changed positively. For the impact of teachers on the students’ views, the teachers’ prior NOS knowledge, years of experience, and the number of implemented activities were found to be the influential factors for the transmission of NOS views.

In the educational sciences, many discussions on the use of computer games occur. Most of the scientists believe that traditional computer games are time-consuming software and that game-playing activities negatively affect students’ academic performance. In this study, the accuracy of this general opinion was examined by focusing on the real game-playing scores of an elementary school students in Turkey. First, researchers selected a single-player strategy game. Second, the selected game was given to 105 fifth-grade students, who had not played it before, so that they could play it over a 30-minute period. The most successful student of the group finished the 23rd level of the game and collected 8152 points in total. In order to investigate the correlation between strategy game performance and academic performance, researchers derived the students’ average exam scores for six different courses (mathematics, physical science, science and technology, visual arts, music, and social sciences) from official documents. At the end of the study, it was found that participants’ mathematical or physical science skills were positively correlated with game success; however, a negative relationship was not exists between an individual's computer game success and academic performance. 相似文献

Understandings of current environmental issues: Turkish case study in six teacher education colleges
The purpose of this study is to profile future science teachers’ understandings of current environmental issues in the context of an education reform in Turkey. Knowledge base and understandings of elementary and secondary prospective science teachers about biodiversity, carbon cycle, global warming and ozone layer depletion were targeted in the study. Questionnaire surveys developed for this purpose were adapted and used in this investigation. The questionnaires were administered to 360 participants in six universities. Analysis involved frequencies, percentages and comparing means for students majoring in elementary and secondary science teaching. Analysis of variance for differences among majors and responses to different issues are also included. Findings are compared and contrasted with the previous research in other countries. The study has implications for the prospective preparation of teachers and the future of environmental literacy movement in Turkey. 相似文献

Though initially proposed as a means of overcoming common barriers to higher education, MOOCs often exacerbate the very issues of accessibility and exclusivity that they were designed to avoid. Students from developing countries in particular face considerable obstacles that hinder or outright prevent their enrollment in and completion of MOOCs. This study finds that, for these students, participation in MOOCs is often complicated by language barriers, limited technological resources, and prevailing Americentric or Eurocentric designs and mindsets, among other issues. These findings were determined and reinforced by a study of Turkish college students from a large state-sponsored metropolitan university, who indicated different levels of knowledge regarding MOOCs as well as various issues, concerns, and complaints. These issues of accessibility and exclusivity must be addressed before MOOCs will truly be able to democratize access to high-quality university-level education, and the best solutions are those that acknowledge the multicultural nature of their user communities. 相似文献

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65–83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country. 相似文献
