Development and Validation of a Multimedia-based Assessment of Scientific Inquiry Abilities     

Che-Yu Kuo  Tsung-Hau Jen  Ying-Shao Hsu 《International Journal of Science Education》2013,35(14):2326-2357

The potential of computer-based assessments for capturing complex learning outcomes has been discussed; however, relatively little is understood about how to leverage such potential for summative and accountability purposes. The aim of this study is to develop and validate a multimedia-based assessment of scientific inquiry abilities (MASIA) to cover a more comprehensive construct of inquiry abilities and target secondary school students in different grades while this potential is leveraged. We implemented five steps derived from the construct modeling approach to design MASIA. During the implementation, multiple sources of evidence were collected in the steps of pilot testing and Rasch modeling to support the validity of MASIA. Particularly, through the participation of 1,066 8th and 11th graders, MASIA showed satisfactory psychometric properties to discriminate students with different levels of inquiry abilities in 101 items in 29 tasks when Rasch models were applied. Additionally, the Wright map indicated that MASIA offered accurate information about students’ inquiry abilities because of the comparability of the distributions of student abilities and item difficulties. The analysis results also suggested that MASIA offered precise measures of inquiry abilities when the components (questioning, experimenting, analyzing, and explaining) were regarded as a coherent construct. Finally, the increased mean difficulty thresholds of item responses along with three performance levels across all sub-abilities supported the alignment between our scoring rubrics and our inquiry framework. Together with other sources of validity in the pilot testing, the results offered evidence to support the validity of MASIA.  相似文献   

Does STES‐Oriented Science Education Promote 10th‐Grade Students’ Decision‐Making Capability?     

Tami Levy Nahum  David Ben‐Chaim  Ibtesam Azaiza  Orit Herskovitz 《International Journal of Science Education》2013,35(10):1315-1336

Today’s society is continuously coping with sustainability‐related complex issues in the Science‐Technology‐Environment‐Society (STES) interfaces. In those contexts, the need and relevance of the development of students’ higher‐order cognitive skills (HOCS) such as question‐asking, critical‐thinking, problem‐solving and decision‐making capabilities within science teaching have been argued by several science educators for decades. Three main objectives guided this study: (1) to establish “base lines” for HOCS capabilities of 10th grade students (n = 264) in the Israeli educational system; (2) to delineate within this population, two different groups with respect to their decision‐making capability, science‐oriented (n = 142) and non‐science (n = 122) students, Groups A and B, respectively; and (3) to assess the pre‐post development/change of students’ decision‐making capabilities via STES‐oriented HOCS‐promoting curricular modules entitled Science, Technology and Environment in Modern Society (STEMS). A specially developed and validated decision‐making questionnaire was used for obtaining a research‐based response to the guiding research questions. Our findings suggest that a long‐term persistent application of purposed decision‐making, promoting teaching strategies, is needed in order to succeed in affecting, positively, high‐school students’ decision‐making ability. The need for science teachers’ involvement in the development of their students’ HOCS capabilities is thus apparent.  相似文献   

Measured lives: the rise of assessment as the engine of change in English schools     

Mary James 《Curriculum Journal》2013,24(3):343-364

The year 2000 marks the end of compulsory education for the first cohort of students to experience the National Curriculum throughout their school careers. This article describes their experience of assessment and compares it with the testing regime that those children who start school in 2000 are likely to experience. Changes in policy from the early Task Group on Assessment and Testing proposals are analysed, especially the increasing priority given to the use of assessment for monitoring and evaluating the performance of teachers, schools and local education authorities. This shift is interpreted in terms of underlying assumptions about effective strategies for change. While Conservative and Labour governments have pursued somewhat different goals, they have used a similar change strategy. This explains why the general thrust of policy has continued in a broadly similar direction - towards ever more testing in schools and the use of results as performance indicators. It is argued, however, that this strategy cannot be pursued indefinitely. After a point, further improvements will only be made if teachers are helped to work ‘smarter’, not just harder. Policy-makers need, therefore, to look again at the contribution that formative assessment - or assessment for learning as part of pedagogy - can make to lifelong learning, in a more coherent, balanced and ‘educational’ system.  相似文献

Connecting Forensics and Assessment in the Twenty-First Century     

Kristopher Copeland  Jacob Stutzman  Sarah Collins 《Communication Studies》2015,66(4):474-486

A major feature of education in the twenty-first century is assessment. Forensic educators should heighten the importance of learning outcomes and utilize assessment efforts to directly measure how forensic programs develop educational foundations for students. This article focuses on the use of tournaments and noncompetitive educational outcomes, such as engagement within academic communities, service-learning, and the promotion of the value of forensics, to connect the educational benefits of the activity to help define the mission of forensics in the twenty-first century.  相似文献   

Motivation and transfer in professional training: A meta-analysis of the moderating effects of knowledge type, instruction, and assessment conditions     

Andreas Gegenfurtner 《Educational Research Review》2011,6(3):153-168

This meta-analysis (148 studies, k = 197, N = 31,718) examined the relationship between motivation and transfer in professional training. For this purpose, motivation was conceptualized in the following nine dimensions: motivation to learn, motivation to transfer, pre- and post-training self-efficacy, mastery orientation, performance orientation, avoidance orientation, expectancy, and instrumentality. Population correlation estimates ranged between −0.11 and 0.52. Three moderator effects were estimated. First, correlations were higher when the training focused on declarative and self-regulatory, rather than on procedural, knowledge. Second, learner-centered environments tended to show greater numbers of positive correlations than did knowledge-centered environments. Third, when compared with external, supervisory, or peer assessment, self-assessment of transfer produced upwardly biased population estimates irrespective of the transfer criterion. These findings are discussed in terms of their implications for theories of training effectiveness and their significance for the practice of training evaluation.  相似文献
