Recommendations for improving the assessment of postgraduate dental education.

This paper makes recommendations for the improvement of assessment in postgraduate dental education. The recommendations are based on a twelve-month study conducted in 1998/99 which evaluated the strengths and weaknesses of the existing assessment systems. Evidence was taken from examination syllabi, assessments and records. Semi-structured interviews were conducted with representatives from national bodies and with trainers and trainees in the West Midlands. Strengths in parts of the system include: commitment and professional experience; commissioned work; opportunity to share experience; a monitoring framework; procedures for maintaining standards and examples of broadbased assessments. Weaknesses include: lack of assessment of quality; existence of some forms of unregulated assessment; lack of transparency and lack of clarity between training and assessment. Development is recommended in three broad areas: a competence-based model of assessment; distinguishing assessment from the analysis of educational needs and quality assurance. The introduction of a competence-based model is the most significant and is addressed in some detail. Specific proposals for consideration by national regulatory bodies and education providers include: strengthening the management of assessment; national leadership in the development of a competence model of assessment; widening the assessment base; clearer criteria for inspection; revisions to how vocational training, HO/SHO training and general professional training are assessed and training for trainers.

Assessment in postgraduate dental education: an evaluation of strengths and weaknesses.

UNLABELLED: This paper describes a study designed to evaluate assessment in postgraduate dental education in England, identifying strengths and weaknesses and focusing specifically on its relevance, consistency and cost-effectiveness. METHODS: A four-phase qualitative method was used: a mapping of current career paths, assessment policy, and issues (phase 1); more detailed studies of the practice of assessment for a range of courses, and the systemic/management perspective of assessment (i.e. quality assurance) (phases 2 and 3), and analysis and reporting (phase 4). Data were analysed from documents, interviews, group consultations and observations. RESULTS AND DISCUSSION: Five key issues may be distilled from the findings: (i) lack of formal assessment of general professional training; (ii) trainer variation in assessment; (iii) the extent to which assessments are appropriate indicators of later success; (iv) the relationship between assessment and patient care, and (v) data to assess the costs of assessment. CONCLUSION: Current assessment procedures might be improved if consideration is given to: assessment which supports an integrated period of general professional training; training for trainers and inspection procedures to address variation; more authentic assessments, based directly on clinical work and grading cases and posts, and better data on allocation of resources, in particular clinicians' time given to assessment.

A role for clinical audit and peer review in the identification of continuing professional development needs for general dental practitioners: a discussion.

The purpose of this paper is to discuss how the role of peer review and clinical audit may be used in the identification of the continuing professional development (CPD) needs of general dental practitioners (GDPs). Clinical audit and peer review are intrinsically valuable in terms of the continued professional development of GDPs. Collaborative clinical audit, in particular, can provide a framework for short course input and there are particular benefits to this combination of activities which might usefully be more widely encouraged. If open to analysis in a way which retains individual anonymity, peer review and clinical audit resumes, these could be used to inform the provision of CPD and, linked to the knowledge of audit facilitators, short courses might more closely match the CPD needs of local dentists.

A framework for the evaluation of continuing education short courses in dentistry.

The objective of this paper is to propose an evaluation framework for short courses in continuing education for general dental practitioners (GDPs) (so called, Section 63 courses). Existing monitoring and evaluation procedures in the West Midlands deanery were examined and an improved evaluation framework was then devised, piloted and revised. A 5 phase method was used incorporating the examination of existing practice (Phases 1 and 2), development of a new framework (Phase 3), piloting (Phase 4) and revision of the evaluation framework in the light of the pilot. This approach will be implemented in the West Midlands and may be adapted for national use (Phase 5). It was found that existing monitoring and evaluation was inconsistent in prevalence and scope. Those involved in short courses were in favour of a more consistent and visible evaluation, including some assessment of impact-on-practice and cost-effectiveness. In conclusion, meaningful evaluation needs to include four key processes: data gathering; data analysis; dissemination and, action planning (reviewing provision in the light of the data analysis). Thus, this evaluation framework feeds into a quality development cycle designed to ensure high quality and relevant short course provision for general dental practitioners.

Continuing education courses in dentistry: assessing impact on practice.

INTRODUCTION: In the context of movement towards mandatory continuing dental education, this paper describes how a delayed postal questionnaire can be used in course evaluation. Specifically, the value of the questionnaire as a tool for assessing the impact of short course attendance on general dental practice is examined. METHOD: Questionnaires were distributed to all those attending three courses, ranging in size, in the West Midlands region. As well as reflecting on the course, respondents were asked their views on the usefulness of the questionnaire, the length of time between course attendance and assessment of impact, and types of courses likely to have greatest impact. RESULTS: Respondents thought the questionnaire an appropriate tool for assessing impact on practice, that an appropriate interval of time between the course and the delayed questionnaire is about six weeks, and that courses most likely to impact on practice are those which offer updates on common clinical topics and are hands-on in nature. DISCUSSION: A delayed questionnaire could be a useful mechanism for evaluating the impact on practice of some types of courses. Response rates from those attending large lecture courses might be low. Course evaluation is also limited by resources and time. Criteria for identifying which courses should be subject to such evaluation might include high cost per participant and links with review cycles. CONCLUSION: There is scope for more structured evaluation of continuing dental education, including the assessment of impact on practice. The questionnaire described is a useful component of an evaluation framework.

The possible-word constraint in the segmentation of continuous speech.

We propose that word recognition in continuous speech is subject to constraints on what may constitute a viable word of the language. This Possible-Word Constraint (PWC) reduces activation of candidate words if their recognition would imply word status for adjacent input which could not be a word--for instance, a single consonant. In two word-spotting experiments, listeners found it much harder to detect apple, for example, in fapple (where [f] alone would be an impossible word), than in vuffapple (where vuff could be a word of English). We demonstrate that the PWC can readily be implemented in a competition-based model of continuous speech recognition, as a constraint on the process of competition between candidate words; where a stretch of speech between a candidate word and a (known or likely) word boundary is not a possible word, activation of the candidate word is reduced. This implementation accurately simulates both the present results and data from a range of earlier studies of speech segmentation.

The strong/weak syllable distinction in English.

Strong and weak syllables in English can be distinguished on the basis of vowel quality, of stress, or of both factors. Critical for deciding between these factors are syllables containing unstressed unreduced vowels, such as the first syllable of automata. In this study 12 speakers produced sentences containing matched sets of words with initial vowels ranging from stressed to reduced, at normal and at fast speech rates. Measurements of the duration, intensity, F0, and spectral characteristics of the word-initial vowels showed that unstressed unreduced vowels differed significantly from both stressed and reduced vowels. This result held true across speaker sex and dialect. The vowels produced by one speaker were then cross-spliced across the words within each set, and the resulting words' acceptability was rated by listeners. In general, cross-spliced words were only rated significantly less acceptable than unspliced words when reduced vowels interchanged with any other vowel. Correlations between rated acceptability and acoustic characteristics of the cross-spliced words demonstrated that listeners were attending to duration, intensity, and spectral characteristics. Together these results suggest that unstressed unreduced vowels in English pattern differently from both stressed and reduced vowels, so that no acoustic support for a binary categorical distinction exists; nevertheless, listeners make such a distinction, grouping unstressed unreduced vowels by preference with stressed vowels.

The perception of rhythm and word boundaries in noise-masked speech.

The present experiment tested the suggestion that human listeners may exploit durational information in speech to parse continuous utterances into words. Listeners were presented with six-syllable unpredictable utterances under noise-masking, and were required to judge between alternative word strings as to which best matched the rhythm of the masked utterances. For each utterance there were four alternative strings: (a) an exact rhythmic and word boundary match, (b) a rhythmic mismatch, and (c) two utterances with the same rhythm as the masked utterance, but different word boundary locations. Listeners were clearly able to perceive the rhythm of the masked utterances: The rhythmic mismatch was chosen significantly less often than any other alternative. Within the three rhythmically matched alternatives, the exact match was chosen significantly more often than either word boundary mismatch. Thus, listeners both perceived speech rhythm and used durational cues effectively to locate the position of word boundaries.
