Construct Validation of the Perceptions of Assessment Tasks Inventory
Get PDFIntroduction: Students\u27 perceptions of the assessment tasks can be a basis for optimizing the classroom assessment environment. In an attempt to quantify students\u27 perceptions of assessment, Dorman and Knightley (2006) developed Perceptions of Assessment Tasks Inventory (PATI). This study sought to provide evidence for the construct validity of the PATI. Method: A descriptive research design was employed in this study. Using a cluster sampling process, the participants were 330 Omani students (175 females and 155 males) enrolled in grade 11 science classes. Three instruments were used in the study concerning self-efficacy, perceptions of classroom assessment environment, and perceptions of assessment tasks. Data were analyzed using confirmatory factor analysis, cluster analysis, multivariate analysis of variance, one-way analysis of variance, and Pearson product-moment correlation analysis. Results: Results indicated that a five-factor structure of the PATI provided a good fit to the observed data. Cluster analyses suggested three clusters of students who were distinct with regard to their perceptions of the assessment tasks. Scores of the PATI subscales correlated positively with perceived learning assessment environment and negatively with perceived performance assessment environment. The PATI scores had acceptable levels of internal consistency reliability.Conclusion: In conclusion, the results support the utility of the PATI for research and instructional purposes. It offers information that can be used by teachers to better orient classroom assessment toward improved student motivation and learning. Researchers might need to conduct studies linking between perceptions of assessment tasks and other characteristics of students and teachers
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Psychometric properties of the teacher assessment literacy questionnaire for preservice teachers in Oman
No full textAbstractThis study examined psychometric properties of the Teacher Assessment Literacy Questionnaire (TALQ) developed by Plake and Impara (1992) to measure teachers’ assessment literacy. Preservice teachers (N = 259) enrolled in an educational measurement course in Oman completed the TALQ. Results showed that (a) the items demonstrated acceptable levels of difficulty, discrimination, reliability, and validity; (b) the TALQ measures a unitary construct of the assessment literacy; (c) the TALQ's scores had an adequate internal consistency; and (d) the TALQ's scores correlated positively with total course’ scores. Percentile ranks were extracted as norms for the raw scores. The results support the utility of the TALQ for instructional and assessment purposes
Variations on the Author
Get PDF“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
Get PDFWe 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

Get PDFDispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Predicción del logro académico de los estudiantes: contribuciones desde la percepción de tareas de evaluación en el aula y estrategias de aprendizaje motivado
No full textIntroduction. Students are daily exposed to a variety of assessment tasks in the classroom. It has long been recognized that students’ perceptions of the assessment tasks may influence student academic achievement. The present study aimed at predicting academic achievement in mathematics from perceptions of the assessment tasks after controlling for gender and motivated learning strategies.Method. The participants were 232 students enrolled in grade 11 mathematics classes selected from public schools in Oman. Data were collected using the Motivated Strategies for Learning Questionnaire and Perceptions of Assessment Tasks Inventory. Students’ final grades earned in the subject were obtained from the school administration at the end of the semester.Results. A hierarchical multiple regression analysis showed that consultation and transparency were significantly related to mathematics achievement after controlling for gender and motivated learning strategies.Discussion. The findings contributed to the existing assessment literature by demonstrating the intersection between classroom assessment and self-regulation of learning and their effects on student achievement. Implications and recommendations for research and practice were discussed.</jats:p
