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.     

论民事诉讼法中诚实信用原则的确立

关于诚实信用原则的适用范围能否成为民事诉讼法的基本原则,理论上的争论早已存在,其中关键在于诚实信用原则是否具备独立价值和意义,以及适合民事诉讼法的土壤能否生存。从三方面阐述并论证诚实信用原则在民事诉讼法中被确立为基本原则的必然性,从而得出:在当代民事诉讼理论及实践的大背景下,确立诚实信用原则具有积极的意义。     

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.

How to encourage a lifelong learner? The complex relation between learning strategies and assessment in a medical curriculum

Abstract

To foster lifelong learning skills, we need new didactic approaches with aligned assessment methods. Therefore, we investigated whether the outcomes of a project assignment show a different relation to learning strategies than a longitudinal knowledge-based assessment. We studied learning strategies of first year students of medicine and biomedical sciences (n?=?248) and performed hierarchical regression analyses for the learning strategies and grades of the longitudinal knowledge-based test and project assignment. Scores of students, measured with the Motivated Strategies for Learning Questionnaire (Likert scale 1–7), were relatively low for critical thinking (3.53), compared to rehearsal (4.40), elaboration (4.82), organisation (4.69) and metacognitive self-regulation (4.33). Knowledge based tests showed a significant relation to elaboration (p?<?0.01). For the project-based assessment, we did not find a significant relation to any learning strategy (p?=?0.074). Explained variance of the grades was low for all learning strategies (R² < 0.043). Different types of assessment did not discriminate between students with high or low scores on learning strategies associated with lifelong learning. An explanation is that the curriculum is not aligned with assessment, or students do not benefit in terms of grades. We conclude that, if assessment is to drive lifelong learning skills, this is not self-evident.
