To design an effective computer science curriculum, educators require a systematic method of classifying the difficulty level of learning activities and assessment tasks. This is important for curriculum design and implementation and for communication between educators. Different educators must be able to use the method consistently, so that classified activities and assessments are comparable across the subjects of a degree, and, ideally, comparable across institutions. One widespread approach to supporting this is to write learning objects in terms of Bloom’s Taxonomy. This, or other such classifications, is likely to be more effective if educators can use them consistently, in the way experts would use them. To this end, we present the design and evaluation of our online interactive web-based tutorial system, which can be configured and used to offer training in different classification schemes. We report on results from three evaluations. First, 17 computer science educators complete a tutorial on using Bloom’s Taxonomy to classify programming examination questions. Second, 20 computer science educators complete a Neo-Piagetian tutorial. Third evaluation was a comparison of inter-rater reliability scores of computer science educators classifying programming questions using Bloom’s Taxonomy, before and after taking our tutorial. Based on the results from these evaluations, we discuss the effectiveness of our tutorial system design for teaching computer science educators how to systematically and consistently classify programming examination questions. We also discuss the suitability of Bloom’s Taxonomy and Neo-Piagetian theory for achieving this goal. The Bloom’s and Neo-Piagetian tutorials are made available as a community resource. The contributions of this paper are the following: the tutorial system for learning classification schemes for the purpose of coding the difficulty of computing learning materials; its evaluation; new insights into the consistency that computing educators can achieve using Bloom; and first insights into the use of Neo-Piagetian theory by a group of classifiers.  相似文献

This paper is based on a multiple-case study of the learning process in three asynchronous computer conferences. The conferences were part of the distance learning component in doctoral degree courses in computing technology in education offered at an American university. The conferences were analyzed from a number of perspectives, the emphasis in this paper being on the dimensions of interaction and cognition. Although similar interaction patterns were identified in the three conferences, each conference also showed distinctive patterns, which were related to factors such as instructor moderation, structuring of the instructional task and the emergence of student moderation of the discussion in specific threads. Three models were used to evaluate cognition: Bloom's Taxonomy (Bloom, Engelhart, Furst, Hill, & Krathwohl, Handbook 1, Cognitive Domain, Longman, London, 1956), the SOLO Taxonomy (Biggs & Collis, Evaluating the Quality of Learning: The SOLO Taxonomy, Academic Press, New York, 1982) and the Practical Inquiry Model of Cognitive Presence (Garrison, Anderson & Archer, The American Journal of Distance Education 15(1)7, 2001). Correspondences were found among the three models and all three conferences were characterized by higher-order thinking. When higher-order thinking was defined in terms of the distributed cognition occurring during practical inquiry, the advanced phases of cognition were found to be related to synergistic interaction in the conference threads. The findings serve to define the knowledge-building processes occurring in asynchronous computer conferencing. They also lend support to views of learning as dialogical and to social constructivist approaches to learning and teaching.  相似文献

Higher education has traditionally privileged language-based text as evidence of students’ levels of critical thinking and literacy. Twenty-first century education at all levels however, has focused on multimodal literacies and how educators can engage students who are seeing the world through diverse representations and a myriad of forms. Many scholars maintain that we live in a visual culture where we are becoming increasingly proficient at reading images of all kinds. However, our criteria for assessing student learning and measures of assessment have not moved much beyond the traditional written texts outside art and design disciplines. While much has been written about the role of visual literacy, there is little research on assessing visual literacy competencies. This paper proposes a Visual Literacy Competency (VLC) rubric based on the Biggs and Collis (1982. Evaluating the Quality of Learning: The SOLO Taxonomy (Structure of the Observed Learning Outcome). New York: Academic Press) SOLO taxonomy and describes applications for assessing assignments in two undergraduate communications courses with a focus on further developing and shaping student learning.  相似文献

For five years, from 1995 until 2000, a group of eight educators and researchers met twice annually in Syracuse, NY, for the purpose of revising Bloom's Taxonomy. Based in part on the structure of educational objectives, in part on advances in cognitive psychology, and in part on numerous other attempts to classify educational objectives that were made since the publication of Bloom's Taxonomy, this group produced a two-dimensional table, known simply as the Taxonomy Table. The horizontal dimension was a modification of Bloom's Taxonomy, with verb forms replacing the noun forms of the original category labels: Remember, Understand, Apply, Analyze, Evaluate, and Create. The vertical dimension consisted of four types of knowledge: Factual Knowledge, Conceptual Knowledge, Procedural Knowledge, and Metacognitive Knowledge. The purposes of this article are to (1) describe the major differences between the original Taxonomy and the Taxonomy Table, (2) discuss ways in which the Taxonomy Table can be used to examine and ultimately improve the quality of assessment and instruction, and (3) explore how the Taxonomy Table can be used to provide more accurate estimates of curriculum alignment and opportunity to learn.  相似文献

Validity evidence based on test content is critical to meaningful interpretation of test scores. Within high-stakes testing and accountability frameworks, content-related validity evidence is typically gathered via alignment studies, with panels of experts providing qualitative judgments on the degree to which test items align with the representative content standards. Various summary statistics are then calculated (e.g., categorical concurrence, balance of representation) to aid in decision-making. In this paper, we propose an alternative approach for gathering content-related validity evidence that capitalizes on the overlap in vocabulary used in test items and the corresponding content standards, which we define as textual congruence. We use a text-based, machine learning model, specifically topic modeling, to identify clusters of related content within the standards. This model then serves as the basis from which items are evaluated. We illustrate our method by building a model from the Next Generation Science Standards, with textual congruence evaluated against items within the Oregon statewide alternate assessment. We discuss the utility of this approach as a source of triangulating and diagnostic information and show how visualizations can be used to evaluate the overall coverage of the content standards across the test items.  相似文献

A major assumption of problem-based learning (PBL) is that learning issues, generated by students while discussing a problem, are used as guides for self-directed learning activities. This assumption, though basic to PBL, has never been tested. At the University of Limburg, the Netherlands, two procedures have been developed that reflect the extent to which students are able to identify important learning issues given a particular problem, and whether subsequent, independent, learning corresponds with these learning issues. The focus of the present article will be on the relationship between the two. We have explored to what extent student-generated learning issues are a major factor influencing the nature of students' self-study, or whether other factors may be involved in decisions on what to study and how much time to spend on topics selected. First, the production of learning issues was studied and represented as the percentage of overlap between learning issues raised by students and pre-set faculty objectives for each problem. The second procedure consisted of the administration of a Topic Checklist (TOC) which purports to measure students' actual self-directed learning activities. The TOC consists of a list of topics specifying the intended course content. Students were asked to indicate on a five-point Likert scale how much time they had spent studying each topic and to what degree they had mastered that topic. Third, learning issues and TOC topics were compared directly in a qualitative sense. Comparisons between the procedures revealed that a low proportion of variance of TOC scores could be predicted from the percentage of faculty objectives identified for each problem and the direct match between learning issues and TOC scores. It is concluded that scrutinizing student-generated learning issues and topics covered during self-study may provide information about what content is covered by students in tutorial groups. The discrepancy between the results of the measurements suggests, however, that learning issues produced during group discussion are not the sole source on which students base self-study decisions. Several other factors may be involved, such as tutor guidance, content already covered in previous units, issues raised during sessions with resource persons, and the nature of the learning resources available. Therefore, the relationship between learning issues and content covered during self-study is not as straightforward as is suggested.  相似文献

This paper reports on an investigation into students' understanding of the concept of plant growth. There are three aspects to the research. First, responses of Australian primary students to questions concerning plant growth are compared with those identified in British research (Russell & Watt, 1990). Second, the answers of secondary students, Year 7-Year 12, to questions concerning plant growth were analysed and common categories of responses were identified. Finally, the response categories were considered within the framework offered by the SOLO Taxonomy of Biggs and Collis (1982, 1991). In particular, interest was focused on whether the findings of an earlier study (Levins, 1992) in which cycles of development in the understandings of the concept of evaporation were established, might be observed in the concept of plant growth.

This study compares the equal percentile (EP) and partial credit (PC) equatings for raw scores derived from performance-based assessments composed of free-response (open-ended) items clustered around long reading selections or multistep mathematics problems. Data are from the Maryland School Performance Assessment Program. The results suggest that Masters (1982; Wright & Masters, 1982) partial credit model may be useful for equating examinations composed of moderately easy (or not too difficult)items sharing a first principal component with at least 25% of the total variance. This conclusion appears to hold even in the presence of some level of response dependency for the items within each cluster. Although visible discrepancies were found between PC and EP equated scores in the skewed tail of the score distributions, the direction of these discrepancies is unpredictable. Therefore, it cannot be concluded from the study that the two methods give equivalent results when the distributions are markedly skewed.  相似文献

Tertiary students' knowledge of their own learning and a SOLO Taxonomy   总被引:2,自引:0,他引:2  
This paper is a report of the analysis of statements by 869 students and their 21 lecturers in 12 courses in 5 Faculties in the Queensland University of Technology (QUT). The students and lecturers were asked to write a page about learning. The objectives were to collect data to devise a taxonomy of levels of knowledge of learning held by tertiary students and lecturers and to use this to describe student knowledge to lecturers as a basis for planning for teaching. The statements were categorised, using the SOLO Taxonomy as a model (c.f., Biggs and Collis 1982, 1989), by two trained researchers and checked by the author and a consultant. The majority of responses for both students and lecturers were multistructural. A MANOVA for SOLO levels by deep, surface and achieving motives and strategies showed that as SOLO levels increased surface motives declined and deep motives and strategies assumed more importance. The key concepts in learning identified by a random sample of 100 students were further analysed and described for each SOLO level. A SOLO type model of levels of knowledge of learning is proposed, based on the structure of the responses.  相似文献

This paper focuses on students' ability to transfer modelling performances across content areas, taking into consideration their improvement of content knowledge as a result of a model-based instruction. Sixty-five sixth grade students of one science teacher in an urban public school in the Midwestern USA engaged in scientific modelling practices that were incorporated into a curriculum focused on the nature of matter. Concept-process models were embedded in the curriculum, as well as emphasis on meta-modelling knowledge and modelling practices. Pre–post test items that required drawing scientific models of smell, evaporation, and friction were analysed. The level of content understanding was coded and scored, as were the following elements of modelling performance: explanation, comparativeness, abstraction, and labelling. Paired t-tests were conducted to analyse differences in students' pre–post tests scores on content knowledge and on each element of the modelling performances. These are described in terms of the amount of transfer. Students significantly improved in their content knowledge for the smell and the evaporation models, but not for the friction model, which was expected as that topic was not taught during the instruction. However, students significantly improved in some of their modelling performances for all the three models. This improvement serves as evidence that the model-based instruction can help students acquire modelling practices that they can apply in a new content area.  相似文献

The comparability of examinations in different subjects has been a controversial topic for many years and a number of criticisms have been made of statistical approaches to estimating the ‘difficulties’ of achieving particular grades in different subjects. This paper argues that if comparability is understood in terms of a linking construct then many of these problems are resolved. The Rasch model was applied to an analysis of data from over 600,000 candidates who took the General Certificate of Secondary Education (GCSE) examinations in England in 2004. Thirty‐four GCSE subjects were included in the final model, which estimated the relative difficulty of each grade in each subject. Other subjects failed to fit, as did the fail grade, U. Significant overall differences were found, with some subjects more than a grade harder than others, though the difficulty of a subject varied appreciably for different grades. The gaps between the highest grades were on average twice as big as those between the bottom grades. Differential item functioning (DIF) was found for male and female candidates in some subjects, though it was small in relation to variation across subjects. Implications of these findings for various uses of examination grades are discussed.  相似文献

This paper is a discussion of the use of the SOLO (Structure of Observed Learning Outcomes) Taxonomy (Biggs & Collis, 1982, 1989; Biggs, 1991, 1992a, 1992b; Boulton‐Lewis, 1992, 1994) as a means of developing and assessing higher order thinking in Higher Education. It includes a summary of the research into its use to date as an instrument to find out what students know and believe about their own learning, to assess entering knowledge in a discipline, to present examples of structural organization of knowledge in a discipline, to provide models of levels of desired learning outcomes, and in particular to assess learning outcomes. A proposal is made for further research.  相似文献

This paper deals with the statistical modeling of latent topic hierarchies in text corpora. The height of the topic tree is assumed as fixed, while the number of topics on each level as unknown a priori and to be inferred from data. Taking a nonparametric Bayesian approach to this problem, we propose a new probabilistic generative model based on the nested hierarchical Dirichlet process (nHDP) and present a Markov chain Monte Carlo sampling algorithm for the inference of the topic tree structure as well as the word distribution of each topic and topic distribution of each document. Our theoretical analysis and experiment results show that this model can produce a more compact hierarchical topic structure and captures more fine-grained topic relationships compared to the hierarchical latent Dirichlet allocation model.  相似文献

The diversity of engineering education research provides an opportunity for cross-fertilisation of ideas and creativity, but it also can result in fragmentation of the field and duplication of effort. One solution is to establish a standardised taxonomy of engineering education terms to map the field and communicate and connect research initiatives. This report describes the process for developing such a taxonomy, the EER Taxonomy. Although the taxonomy focuses on engineering education research in the United States, inclusive efforts have engaged 266 individuals from 149 cities in 30 countries during one multiday workshop, 7 conference sessions, and several other virtual and in-person activities. The resulting taxonomy comprises 455 terms arranged in 14 branches and 6 levels. This taxonomy was found to satisfy four criteria for validity and reliability: (1) keywords assigned to a set of abstracts were reproducible by multiple researchers, (2) the taxonomy comprised terms that could be selected as keywords to fully describe 243 articles in 3 journals, (3) the keywords for those 243 articles were evenly distributed across the branches of the taxonomy, and (4) the authors of 31 conference papers agreed with 90% of researcher-assigned keywords. This report also describes guidelines developed to help authors consistently assign keywords for their articles by encouraging them to choose terms from three categories: (1) context/focus/topic, (2) purpose/target/motivation, and (3) research approach.  相似文献

The topic of test reliability is about the relative consistency of test scores and other educational and psychological measurements. In this module, the idea of consistency is illustrated with reference to two sets of test scores. A mathematical model is developed to explain both relative consistency and relative inconsistency of measurements. A means of indexing reliability is derived using the model. Practical methods of estimating reliability indices are considered, together with factors that influence the reliability index of a set of measurements and the interpretation that can be made of that index.  相似文献

Little research has been conducted to differentiate between multiple, and frequently simultaneously available, discrete object foci in academic achievement situations that emotions can be generated from, including technology and academic topics. Using R. Pekrun’s control-value theory of achievement emotions and Sharples and colleagues’ Mobile Learning Theory, we examined whether appraisals of control over technology and task value predicted emotions directed toward using a mobile app (technology-related emotions) and queer history content (topic emotions). In turn, we examined whether technology-related and topic emotions predicted objective and subjective knowledge outcomes. The main results of this study that examined 57 undergraduate students at a Canadian University were the following: (1) Learners reported high mean levels of technological control over the app. (2) Relatively high mean levels of task value. (3) High mean levels of enjoyment and low mean levels of boredom across both technology-related and topic emotions. (4) Learners’ appraisals of task value contributed to multiple regression models that statistically significantly predicted all emotions; appraisals of control over technology contributed to the multiple regression model (along with task value) that statistically significantly predicted technology-related enjoyment. And (5) technology-related enjoyment and topic boredom contributed to multiple regression models that statistically significantly predicted perceived success of learning. Findings and implications are discussed from a critical-analytical perspective.  相似文献

Support is needed to promote problem-based learning (PBL) and to enhance critical thinking skills in discussion-based Internet forums. By advancing the capabilities of chat room and forum software, problem-based discussions for learning can be supported further in online learning environments. In this paper, the authors report on MALESAbrain, an intelligent learning tool. The model is built on the notions of threshold and knowledge weight from the discipline of machine learning. The model encourages learners to judge or critically evaluate the solutions posted by others before exploring further knowledge content. The system then sums up the judgment scores as its knowledge weight to pass the thresholds setup for ranking/arranging the learning issues. This constraint design, therefore, becomes a mechanism for critical thinking in a problem-based learning activity. MALESAbrain as a model helps transform the forum and chat room into rich learning discussion environments.  相似文献
