The aims of this study were to evaluate reliability and validity of the Students’ Perception of Assessment Questionnaire (SPAQ), to evaluate students’ perception on assessment, and to evaluate gender‐based, grade‐based, and ethnicity‐based differences in students’ perceptions. The validity and reliability coefficients revealed that the SPAQ was suitable for assessing students’ perceptions on five assessment dimensions. The average scale‐item mean values for all the scales were less than 3.0, which indicates a need to address these dimensions of assessment at classroom level. The mean value for Student Consultation scale was 1.96 out of 4, indicating a need for special attention in this area. The perceptions of students grouped on the basis of gender and of grade level groups were comparable, but on the basis of ethnic groups were statistically significantly different. Assuming these differences to be real, does it mean that teaching approaches will need to be addressed? Future research in this area is warranted. 相似文献

Methods of statistical process control were briefly investigated in the field of educational measurement as early as 1999. However, only the use of a cumulative sum chart was explored. In this article other methods of statistical quality control are introduced and explored. In particular, methods in the form of Shewhart mean and standard deviation charts are introduced as techniques for ensuring quality in a measurement process for rating performance items in operational assessments. Several strengths and weaknesses of the procedures are explored with illustrative real and simulated rating data. Further research directions are also suggested . 相似文献

e-Government readiness varies significantly across nations. This research explored the relationship of national culture values and practice to e-Government readiness. Eighteen hypotheses were formulated and tested. With the exception of performance orientation and assertiveness, national culture values and practices correlated negatively and positively with e-Government readiness. In addition, gender egalitarianism, institutional collectivism, performance orientation, and uncertainty avoidance values were found to be key determinants of e-Government readiness. The findings of this research provide a foundation for culturally-based policies and strategies aiming at enhancing e-Government readiness across nations. 相似文献

THE DIMENSIONS OF EXPRESSION INHIBITION: PERCEPTIONS OF OBSTACLES TO FREE SPEECH IN THREE CULTURES 总被引:1,自引:0,他引:1

As part of a comparative study of attitudes toward freedom ofexpression, Americans, Israeli Jews, and Israeli Arabs wereasked about the social contexts in which they feel unfree tospeak and about the reasons that inhibit them. Home was theleast inhibiting locus in all three cultures and, for the U.S.respondents, the workplace was most inhibiting. Responding toa battery of 33 reasons for not speaking out, all three culturesgave highest ratings to items related to the fear of hurtingothers. Questions measuring fear of being disapproved or hurtby othersincluding fear of isolation from the majorityand fear of legal restraintwere ranked lower. An overallindex of inhibition items proved highly reliable cross-culturally.Americans claimed least inhibition and Israeli Arabs most. Malesand those with higher education levels and incomes were alsoless inhibited across the three cultures. Expression inhibitionwas negatively, through weakly, related to support for expressiverights among both Israeli groups and American whites but notAmerican blacks, where the relation was positive. Expressioninhibition was negatively related to political activity amongAmericans and Israeli Jews but not among Arabs. 相似文献

AbstractThis study examines the promotion and knowledge of online patent literature search among students, librarians, and instructors to enhance university scientific output in Zanzibar. The study was guided by four key questions: What is the level of awareness of students, instructors and library staff about patent documents as source of information? To what extent do students and instructors access online patent databases? What is the library experience in training students about online patent literature searching?, and what are the challenges facing library and instructors in promoting patent literature search? The study used survey approach whereby questionnaire and interview were used to collect data. The recent literatures regarding online patent literature searching were also critically reviewed. A survey was conducted at two Universities in Zanzibar namely the State University of Zanzibar and Zanzibar University, whereby 20 library staff, 10 instructors and 140 undergraduate students from the School of Computing and the Faculty of Engineering were involved in this study. The findings show that more than three quarters of respondents were either partially aware or not aware at all about the existence of free online patent databases. Likewise, the majority of students had no enough skills of patent literature searching. However, usually the library organizes training on general online literature searching skills but patent literature searching was not effectively taught and a big challenge observed in this study regarding promotion of patent literature searching is inadequate patent searching skills among library and instructors. Based on the findings, the study proposed several recommendations to rectify the existing problem. 相似文献

This research presents an enhanced approach for Aspect-Based Sentiment Analysis (ABSA) of Hotels’ Arabic reviews using supervised machine learning. The proposed approach employs a state-of-the-art research of training a set of classifiers with morphological, syntactic, and semantic features to address the research tasks namely: (a) T1:Aspect Category Identification, (b) T2:Opinion Target Expression (OTE) Extraction, and (c) T3: Sentiment Polarity Identification. Employed classifiers include Naïve Bayes, Bayes Networks, Decision Tree, K-Nearest Neighbor (K-NN), and Support-Vector Machine (SVM).The approach was evaluated using a reference dataset based on Semantic Evaluation 2016 workshop (SemEval-2016: Task-5). Results show that the supervised learning approach outperforms related work evaluated using the same dataset. More precisely, evaluation results show that all classifiers in the proposed approach outperform the baseline approach, and the overall enhancement for the best performing classifier (SVM) is around 53% for T1, around 59% for T2, and around 19% in T3. 相似文献
