Fuzzy Comprehensive Assessment Method to Determine Tectonic Stress Patterns

The tectonic stress patterns were determined by a fuzzy comprehensive assessment method. Data of in-situ survey and fault information were utilized in the method. First, by making pressure and tension in the directions of along-river, cross-river, shear clockwise, and shear counterclockwise , 26 types of tectonic stress patterns were presented. And the stress vector of each pattern was obtained with FE software by taking unit displacement as boundary load. Then, by taking the 26 types of tectonic stress patterns as index set and 3 main stresses as factor set and choosing various operators, comparison of directions of computational stress vector and survey stress vector was made and the most possible tectonic stress pattern was obtained. Taking the 26 types of tectonic stress patterns as index set and strike angle as factor set, comparison of relationships between formation of fault and tectonic stress was made,and the tectonic stress patterns were assessed with known fault information. By summarizing the above assessment results, the most impossible tectonic stress pattern was obtained . Finally an engineering case was quoted to validate that the method is more feasible and reliable than traditional empirical method.     

The judgement processes involved in the moderation of teacher-assessed projects

Classroom-based assessments have the potential to enhance validity by facilitating the assessment of important skills that are difficult to assess in written examinations. Such assessments tend to be marked by teachers. To ensure consistent marking standards, quality assurance procedures are needed. In the context of continued debate over the robustness of assessment by teachers, this research aimed to provide insights into the cognitive and social processes involved in the moderation of project work in General Certificate of Secondary Education qualifications (taken by many 16 year olds in England). The research involved nine examiners across three subject areas ‘thinking aloud’ whilst moderating the marks given to six students (treated as a mock school). The participants were also interviewed. These methods were chosen to provide an in-depth look at the judgement processes involved. The research provides an improved understanding of moderation judgements and how aspects of this process relate to existing theories of judgement. Improving our understanding of the judgement processes involved when an examiner moderates teacher marking can help to evaluate the appropriateness of this assessment method, may contribute to debate on whether teacher marking can be sufficiently well verified by quality assurance procedures, and may inform moderation practice.

A model for making decisions about ethical dilemmas in student assessment

In this mixed-methods study we investigated the development of a generalized ethics decision-making model that can be applied in considering ethical dilemmas related to student assessment. For the study, we developed five scenarios that describe ethical dilemmas associated with student assessment. Survey participants (i.e., educators) completed an online survey to express their decision-making process when faced with ethical dilemmas relating to student assessment. Based on the literature and the educators’ written responses to the scenarios, elements to consider in an ethics decision-making model related to student assessment include the following: (1) the critical incident giving rise to the ethical dilemma; (2) identification of the conflict elements; (3) decisions about the ethicality of the elements; (4) justification of the decisions; (5) implications; and (6) alternative suggestions. This model offers guidance to educators in considering the dimensions of an ethical dilemma in assessment prior to making a decision.     

An ecological approach to the on-line assessment of problem-solving paths: Principles and applications

In this paper, we propose a theoretical framework for designing on-line situated assessment tools for multimedia instructional systems. Based on an ecological psychology approach to situated learning, a graph theoretic methodology is applied to monitor students' performance (solution paths) throughout the learning activity. Deviation of the student's path from the target (expert) path generates indicators which can function as alerts to the student and to the instructor. The information collected in the dribble files and presented visually enables the instructor to identify problems quickly and intervene appropriately. The feasibility of the methodology is explored in case studies describing three instructional systems that teach (1) critical thinking and problem-solving skills, (2) principles of hemodynamic monitoring and treatment, and (3) orthodontic treatment, respectively.

Chinese award-winning tutors’ perceptions and practices of classroom-based assessment

This study examines Chinese tertiary award-winning tutors’ perceptions and reported practices of classroom-based assessment. Seventeen tutors in the final stage of a national university teaching contest were individually interviewed. An interview framework was developed using three process dimensions of assessment for learning (AfL). A sequential and iterative analysis of resulting data was conducted based on Miles and Huberman’s protocols for qualitative analysis. Participants demonstrated a complex set of connections between perceptions and practices around issues of sharing standards, delivering feedback and response to external assessments. Results deviate from widely promoted principles of AfL and classroom-based assessment espoused in the international literature; in doing so, they challenge existing research and assumptions about the standardised and international nature of award-winning instructors’ assessment practices. Findings are discussed in relationship to understanding best practices in tertiary assessment, given emerging tertiary education markets. Practical implications for the further development of learning and assessment practices and theoretical implications for the AfL theory are also discussed.     

Validating a computerized scoring system for assessing writing and placing students in composition courses

How do scores from writing samples generated by computerized essay scorers compare to those generated by “untrained” human scorers and what combination of scores, if any, is more accurate at placing students in composition courses? This study endeavored to answer this two-part question by evaluating the correspondence between writing sample scores generated by the IntelliMetric™ automated scoring system and scores generated by University Preparation English faculty, as well as examining the predictive validity of both the automated and human scores. The results revealed significant correlations between the faculty scores and the IntelliMetric™ scores of the ACCUPLACER™ OnLine WritePlacer Plus test. Moreover, logistic regression models that utilized the IntelliMetric™ scores and average faculty scores were more accurate at placing students (77% overall correct placement rate) than were models incorporating only the average faculty score or the IntelliMetric™ scores.     

Assessment of Cooperative Learning: A Goal-Criterion Approach

The problem of assessment of non-traditional teaching techniques has long challenged educational administrators and faculty. The approach to assessment that we followed in this instance employed a model that we developed to assess group learning, variously known as cooperative learning, collaborative learning, or team learning. We applied the model to group-based case study courses that included innovative enhancements such as group exams and group-based role-play. The model required balanced representation among multiple learning criteria arranged in six goal-criterion sets, all drawn from the literature on group learning. We designed a test instrument based on the model and administered the instrument to 85 students near the end of three business strategy courses. Imbalances among criteria in the six goal-criterion sets helped identify and correct weaknesses in course design and in methods of instruction.
