It is of great significance to discriminate good writing and poor writing and Coh-Metrix,a computational tool of reliability and validity,was used to find out the variables distinguishing the quality of students’ timed compositions.Based on the findings,indices of number of words,average words per sentence and Flesch-Kincaid Grade Level(0-12) have a predicative power as a function of essay quality distinguishing well-graded writing and less-graded writing in 90 texts chosen at random.These findings indicate that the textual features of good writing and poor writing lies not in the readability of the text comprehension but longer text with more words embedded in sentences. 相似文献

Over the last decade, the pressure has increased for teachers to facilitate the best possible learning for all children. States
collect much information to ensure that schools are accountable to all students. But is this information helping to improve
provision for a diverse student population in inclusive settings? It is well established that teachers’ attitudes and beliefs
influence students’ learning. Research evidence also shows that teachers seem to face particular difficulties in trying to
understand students who have a disability or are performing poorly. Teacher education could contribute more substantially
towards helping teachers to adequately understand those student characteristics most relevant to learning. This article presents
a model to help understand the complex competency required to assess students adequately. It is suggested that introducing
teachers to a functional language for describing disability could help teachers to focus on enabling learning and development
rather than labelling. 相似文献

In teacher education programmes, written portfolios or text-based self-evaluations are generally used to document the development of student teachers’ competence. However, such approaches do no justice to the complex nature of teaching as they tend to lead to evidence in which teacher competencies are disconnected and removed from the actual teaching practice. In one postgraduate teacher education programme, video narratives were evaluated as a valid way to assess student teachers’ teaching competencies, promoting connections amongst different competencies, situating these in practice and showing their development over time. Data were gathered from self-reports of both teacher educators and student teachers as well as student teachers’ completed video narratives. Most student teachers succeeded in meeting the set criteria for the video narrative assignment with connected video clips and text frames. However, student teachers also came up with only a few video episodes and loosely connected clips, reflections and other sources. Although most of the students during the programme did explicitly reflect upon their personal development towards becoming a teacher, almost none of them explicitly connected these ideas to their long-term development. We conclude that video narratives show potential to be used as a valid assessment of student teachers’ teaching competence. Yet, structured guidance as well as ill-structured assignments are needed in framing assessment of student teachers in teacher preparation: the former to clarify the aims, format and criteria and the latter to enable student teachers to reflect on their teaching in a personally, meaningful way. 相似文献

Background: Many international science curriculum documents mandate that students should be able to participate in argument, debate and decision-making about contemporary science issues affecting society. Termed socioscientific issues, these topics provide students with opportunities to use their scientific knowledge to discuss, debate and defend their decisions and to evaluate the arguments of their peers.
Purpose: This study describes the development and trialling of scenarios based on the socioscientific issue of climate change. The scenarios required students to make and justify a decision and were designed to assess students’ argumentation skills.
Sample: A sample of 162 Year 10 students from five schools in Perth, Western Australia participated in this study.
Design and methods: Recent media articles were reviewed to identify relevant contexts for scenarios related to climate change that could be used to develop and assess students’ argumentation skills. In the first phase, students trialled scenarios about wind farms and hydrogen fuel buses using writing frames with scaffolding questions to generate as many reasons as possible to justify their decision. The responses were categorised into themes which were used to prepare a scoring rubric. In the second phase, students generated written arguments about the scenarios to support their decision. The arguments were analysed using both the scoring rubric developed from the first phase and Toulmin’s argumentation pattern of claim, data, backing, qualifier and rebuttal.
Results: Students’ responses to the scaffolded questions were categorised into themes of agriculture, economy, energy, environment, human impact and ethical factors. The themes of economy and the environment predominated with ethical justifications cited infrequently. An analysis of the arguments generated revealed a majority of students’ responses consisted of a claim and data with backings, qualifiers and rebuttals rarely provided.
Conclusions: Scenarios about climate change socioscientific issues can be used by teachers to both develop and assess students’ argumentation skills in classroom settings. 相似文献

The ability of graduates to proactively develop, adapt and repackage their capabilities (or attributes) is an essential aspect of employability. This study was conducted at Deakin University, where graduate capabilities have been recast as graduate learning outcomes, and employability is frequently referenced. In light of significant curriculum reform to make graduate capabilities prominent, we investigated student perceptions of graduate capabilities and associated learning outcomes, as well as preparation for employment, to better understand how we can engage students in developing and showcasing their employability. We interviewed 45 students across 10 focus groups and qualitatively analysed their responses for commonly recurring themes. Focus groups were completed in two stages with data analysis and adjustment of questions between stages to enable validation and greater depth of understanding. Our analysis suggests that even with capabilities renamed as learning outcomes, students find graduate learning outcomes too generic to be meaningful and are most likely to engage with learning outcomes that are contextualised and assessed. Our case study illustrates ways to combat this – particularly the importance of assessment design and consistent, student-focused communication in engaging students in the development of capabilities and in the curation of evidence for employability. Students also suggest that advice from employers, professionals and recent graduates, and exposure to industry-related experiences could help make graduate capabilities more meaningful. 相似文献

Several concepts have been developed to implement research-oriented teaching in higher education in the last 15 years. The definition of research competences, however, has received minor attention so far. Some approaches to modeling research competences describe these competences along the research process but either focus on a specific academic discipline and/or specific facets or offer no empirical verification for cross-disciplinary approaches. We have developed a new approach to model research competences across various academic disciplines in form of a competence model—the RMRC-K-model. This model comprises five dimensions: skills in reviewing the state of research, methodological skills, skills in reflecting on research findings, communication skills, and content knowledge. In this study, we present an instrument (R-Comp) developed on the basis of this cross-disciplinary competence model. The factorial structure of the R-Comp was examined with data from 391 university students in three groups, either enrolled in a Bachelor’s degree, Master’s degree, or a PhD program. The sample represented various academic disciplines. Results from confirmatory factor analyses supported the hypothesized structure of the R-Comp for the five dimensions in accordance with the RMRC-K-model. Additionally, results provided evidence for a more detailed differentiation of all dimensions with sub-dimensions reflecting theorized facets of the model. Both Cronbach’s α and construct reliability H indicated overall good reliability. Despite limitations to this study, there is some first evidence of a valid and reliable assessment of student research competences. 相似文献

In Europe, national quality assurance systems of higher education have begun to be established. In Finland, this development has had the consequence of forcing universities to take notice of assessment procedures. However, little is known about the procedures taking place in individual academic departments as a result of this pan‐European trend. This article describes how academics currently comprehend quality assessment, paying particular attention to self‐evaluations and quality assurance systems. Altogether, the paper casts light on how academics are responding to the increasing university assessment activities. 相似文献

The present study investigated the problem-solving performance of 101 university students and their interactions with a computer modeling tool in order to solve a complex problem. Based on their performance on the hidden figures test, students were assigned to three groups of field-dependent (FD), field-mixed (FM), and field-independent (FI) learners, and were instructed to use integrated-format materials and Model-It® in order to solve a problem about immigration policy. The results showed that there were significant differences among the three groups of learners in terms of their problem-solving performance. Consequently, the study employed educational data mining (EDM) methods in order to examine how FD and FI learners actually interacted with Model-It® in order to solve the problem. The EDM methods provided rich analytical information and details about learners’ interactions with the computer tool. Implications for designing effective joint cognitive systems are discussed. 相似文献

This study addresses the following questions in cases of suspected child abuse and neglect (CAN) in children up to four years of age: 1) How many professionals intend to seek inter-organizational consultation? 2) What types of organizations do professionals prefer to consult? and 3) What factors can be identified as facilitator(s) or barrier(s) regarding inter-organizational consultation, based on professionals’ experiences? Professionals working with children in 101 organizations in a medium-sized Dutch city were invited to fill in an online questionnaire. The questionnaire included a vignette about a suspected case. Quantitative, qualitative, and social network analysis approaches were used to analyze the data. Seventy-eight questionnaires were available for analysis. Fifty-five respondents (71%) intended to seek inter-organizational consultation. Ten different organization types were mentioned. The most frequently mentioned organization was preventive child healthcare. In total, 82 text fragments from 39 participants were available to analyze barriers and facilitators to inter-organizational consultation, 60 fragments that entailed a facilitator and 22 fragments that entailed a barrier. The text fragments were subdivided into twelve factors. The three factors that were most often identified as a facilitator were ‘support’, ‘undertaking action’, and ‘regard’. Barriers were found in relation to all twelve factors. No specific barrier(s) stood out. This study demonstrated that most professionals are inclined to seek inter-organizational consultation when they suspect CAN. They are especially likely to seek consultation from preventive child health care organizations. Their experiences mainly revealed facilitators and few barriers. The implications for research and practice are also discussed. 相似文献

Over the past 40 years, numerous instruments have been developed to assess the learning environment for a variety of purposes. Despite this plethora of available surveys, there are few that have been developed for use at the primary school level, and even fewer that have been comprehensively validated. This article describes the development of a long-overdue learning environment survey that is suited to primary school students. Evidence to support the validity of the survey, in terms of translation and criterion validity, was guided by Trochim and Donnelly’s (2006) construct validity framework. A pilot test involving one class of 30 students and interviews with six students was used to examine the face validity of individual items. Analyses of data collected from 609 students in 31 classes supported the convergent, concurrent, discriminant and predictive validity, the results of which were all satisfactory. This article is significant in that it provides educators and researchers with a valid tool to assess the learning environment. The instrument, named the Classroom Climate Questionnaire—Primary (CCQ-P), is described and its practical advantages and limitations are discussed. 相似文献

Background: Correct identification of misconceptions is an important first step in order to gain an understanding of student learning. More recently, four-tier multiple choice tests have been found to be effective in assessing misconceptions.
Purpose: The purposes of this study are (1) to develop and validate a four-tier misconception test to assess the misconceptions of pre-service physics teachers (PSPTs) about geometrical optics, and (2) to assess and identify PSPTs’ misconceptions about geometrical optics.
Sample: The Four-Tier Geometrical Optics Test (FTGOT) was developed based on findings from the interviews (n = 16), open-ended testing (n = 52), pilot testing (n = 53) and administered to 243 PSPTs from 12 state universities in Turkey.
Design and Methods: The first phase of the study was the development of a four-tier test. In the second phase of this study, a cross-sectional survey design was used.
Results: Validity of the FTGOT scores was established by means of some qualitative and quantitative methods. These are: (1) content and face validations by six experts; (2) Positive correlations between the PSPTs’ correct scores considering only first tiers of the FTGOT and their confidence score for this tier (r = .194) and between correct scores considering first and third tiers and confidence scores for both of those tiers (r = .218) were found as evidences for construct validity. (3) False positive (3.5%), false negative (3.3%) and lack of knowledge (5.1%) percentages were found to be less than 10% as an evidence for content validity of the test scores. (4) Explanatory factor analysis conducted over correct and misconception scores yielded meaningful factors for the correct scores as an evidence for construct validity. Additionally, the Cronbach alpha coefficients were calculated for correct scores (r = 0.59) and misconception scores (r = 0.42) to establish the reliability of the test scores. Six misconceptions about geometrical optics, which were held by more than 10% of the PSPTs, were identified and considered to be significant.
Conclusions: The results from the present investigation demonstrate that the FTGOT is a valid and reliable instrument in assessing misconceptions in geometrical optics. 相似文献

This yearlong study was implemented in seventh-grade life science classes with the students' regular teacher serving as teacher/researcher. In the study, a method of scoring concept maps was developed to assess knowledge and comprehension levels of science achievement. By linking scoring of concept maps to instructional objectives, scores were based upon the correctness of propositions. High correlations between the concept map scores and unit multiple choice tests provided strong evidence of the content validity of the map scores. Similarly, correlations between map scores and state criterion-referenced and national norm-referenced standardized tests were indicators of high concurrent validity. The approach to concept map scoring in the study represents a distinct departure from traditional methods that focus on characteristics such as hierarchy and branching. A large body of research has demonstrated the utility of such methods in the assessment of higher-level learning outcomes. The results of the study suggest that a concept map might be used in assessing declarative and procedural knowledge, both of which have a place in the science classroom. One important implication of these results is that science curriculum and its corresponding assessment need not be dichotomized into knowledge/comprehension versus higher-order outcomes. © 1998 John Wiley & Sons, Inc.

In order to evaluate the effectiveness of an experimental elementary mathematics field experience course, we have designed
a new assessment instrument. These video-based prediction assessments engage prospective teachers in a video analysis of a
child solving mathematical tasks. The prospective teachers build a model of that child’s mathematics and then use that model
to predict how the child will respond to a subsequent task. In this paper, we share data concerning the evolution and effectiveness
of the instrument. Results from implementation indicate moderate to high degrees of inter-rater reliability in using the rubric
to assess prospective teachers’ models and predictions. They also indicate strong correlation between participation in the
experimental course and prospective teachers’ performances on the video-based prediction assessments. Such findings suggest
that prediction assessments effectively evaluate the pedagogical content knowledge that we are seeking to foster among the
prospective teachers. 相似文献

The purpose of this study was to develop an index to assess and evaluate the competitive advantage of a country’s human resource development system. Based on an extensive literature review, a theoretical model of a human resource development system at the national level (named National Human Resource Development: NHRD) was constructed. The model consists of four factors—supply conditions, demand conditions, environment, and supporting systems—and NHRD system competitiveness was measured by the cumulative sum of a country’s achievement in each of these four factors. The four factors were divided into 10 sub-categories, and 45 indicators were selected based on criteria such as relevance, international comparability, reliability, timeliness, and accessibility. Finally, by using the Analytic Hierarchy Process, the individual weights of the 45 indicators were calculated. In addition, the relationships between the NHRD competitiveness scores of OECD member countries and other relevant variables, including GDP per capita and the scores from other national competitiveness studies, were analyzed to examine the validity of the index. 相似文献
