    DEVELOPING A SELF-EFFICACY SCALE TOWARD PHYSICS SUBJECTS FOR LOWER-SECONDARY SCHOOL STUDENTS

    No full text
    Physics subjects or topics as a part of science education enable students to explore nature and natural events by using physics laws and scientific methods. In the lower-secondary school, physics is a subfield within the science curriculum developed holistically with the broad field curriculum design unlike the subject-centred curriculum in the upper-secondary education. As an important factor that directs the achievement, self-efficacy is one of the predecessors of these cognitive and affective skills. Accordingly, most of the scales which evaluate the students' cognitive or affective skills in the lower-secondary school are related to science course in a general context. This research aimed to develop a valid and reliable scale measuring the students' self-efficacy beliefs toward physics subjects for lower-secondary schools. The sample consists of 2737 students. The draft scale consisted of 52 items and was applied to 1882 students in the first stage. To construct validity of the scale, exploratory factor analysis was performed. The results showed that the scale consisted of single-factor with 28 items. To confirm its factor structure, the scale was applied to 785 students. The research findings indicate that the scale is a valid and reliable instrument to measure the self-efficacy beliefs towards physics subjects.Bolu Abant Izzet Baysal University Scientific Research Projects Committee in Turkey [2016.02.02.1101]The research which supported by funding from the Bolu Abant Izzet Baysal University Scientific Research Projects Committee in Turkey (Project Number: 2016.02.02.1101) was derived from first author's PhD dissertation conducted under the supervision of the second author

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Integrating augmented reality into problem based learning: The effects on learning achievement and attitude in physics education

    This study investigates the effects of Problem Based Learning (PBL) assisted with Augmented Reality (AR) on learning achievement and attitude towards physics subjects as a part of science education. The sample of the study included 91 seventh graders from a province in the north of Turkey. A quasi-experimental design with two experimental groups and a control group was utilized. Based upon marker-based AR technologies, FenAR software was developed to support with PBL activities in the classroom. The experimental results indicated that integrating AR into PBL activities both increased students' learning achievement and promoted their positive attitudes towards physics subjects. This technology contributed to students' long-term retention of the concepts in the field of physics. In semi-structured interviews, the students emphasized that AR applications were more useful, realistic, and interesting for their learning; helped them to understand and analyse the problem scenarios. Apart from educational advantages, AR applications may lead to physical disorders among some of the students. It has been suggested that AR technology can be a potential and effective tool for activating students' positive emotions in PBL process. Moreover, implications on use of AR for physics education and recommendations for further studies are also discussed in the study.Bolu Abant Izzet Baysal University Scientific Research Projects Committee in Turkey [:2016.02.02.1101]The study which supported by funding from the Bolu Abant Izzet Baysal University Scientific Research Projects Committee in Turkey (Project Number:2016.02.02.1101) was derived from first author's PhD dissertation conducted under the supervision of the second author.

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
