Teachers' knowledge of students' knowledge in mathematics problem solving: Correlational and case analyses.

This study examined the relationship of teachers' knowledge of students' knowledge to teachers' mathematics instruction and to students' mathematics problem solving. First-grade teachers (N?=?20) participated in a 4-week workshop in which they were given access to research-based knowledge on children's mathematics learning. Teachers were observed for 16 days throughout the school year. In May, teachers completed interviews and questionnaires about their knowledge and beliefs; their students completed achievement tests. Correlational analyses showed significant positive relationships between teachers' knowledge of students' knowledge and students' mathematics problem-solving achievement. Teachers with more knowledge of their students questioned students about problem-solving processes and listened to their responses. Teachers with less knowledge of their students explained problem-solving processes to students or observed students' solutions. Case analyses of knowledge and behavior of the most effective teacher and the least effective teacher supported these conclusions and showed important differences in how these teachers thought about and used students' knowledge.

A researcher€ducator collaborative interview study of transactional comprehension strategies instruction.

Reading educators are translating the comprehension strategies research of the 1970s and 1980s into strategies-based reading instruction, meshing decoding, comprehension, and interpretational strategies into transactional strategies instruction. The teachers in 1 prototypical program were interviewed to determine their perceptions of program effects. Teacher satisfaction with program effects was also tapped, as were teachers' perceptions about program shortcomings. A unique feature of this study was that the educators responsible for the program helped determine what they would be asked during the systematic interview; that is, an attempt was made to take full advantage of the insider information possessed by the program developers and teachers. In general, the teachers specified a large number of potential program effects acceptable to them. They also identified some potential shortcomings that should be addressed.

Electronic diagnosis of occlusal caries in vitro: adaptation of the technique for epidemiological purposes

OBJECTIVES: The aim was to assess the awareness and knowledge of family physicians about diagnostic and clinical features of fibromyalgia syndrome (FS), and to evaluate the contribution of rheumatology education to the improvement of this knowledge. METHODS: A detailed questionnaire on FS was completed by 172 family physicians. A composite score, based on five items, was constructed to quantitatively assess knowledge of FS (maximum score of 5). A comparison was made between physicians exposed to extensive education on FS (in Beer Sheva medical centre) and physicians without such exposure (in other centres). RESULTS: Ninety-six per cent of the physicians claimed to be familiar with FS. They recognized most of the FS-related symptoms, but had limited knowledge of the diagnostic criteria, treatment modalities and prognosis. Only 55% knew that FS is associated with widespread pain and 25% were familiar with the point count criterion. Physicians trained in Beer Sheva scored significantly higher than those trained elsewhere: 3.0 +/- 1.2 versus 2.4 +/- 1.2, respectively (P = 0.006), and their knowledge of FS treatment was significantly better. CONCLUSION: Family physicians in Israel are quite unfamiliar with the diagnostic criteria of FS, though educational exposure improves their awareness and knowledge.     

Moderate asthma in adults: diagnosis and management in general medical practice

Moderate asthma is a frequent disorder in general medicine. In 1990, the British Thoracic Society published their first guidelines on the management of asthma. Three years later, we have studied, using a questionnaire, the diagnosis and therapeutic criteria of moderate asthma used by general physicians, and comparing these to the guideline recommendations. Out of 46 physicians questioned in Bordeaux, 40 (87 per cent) agreed to participate in the study. Thirty two physicians (80 per cent) described as moderate an asthma which was mild according to the guidelines; eight physicians (20 per cent) described a moderate asthma according to the guidelines; twenty five (63 per cent) considered as severe a moderate asthma according to the recommendations, although eleven (28 per cent) considered it as moderate and four (10 per cent) did not give an opinion. In total, four (10 per cent) judged asthma severity according to the guidelines (Group R), twenty one (52 per cent) over-estimated the severity of moderate asthma (Group S), and fifteen (37 per cent) gave an inconsistent assessment (Group 1). Twenty six (65 per cent) prescribed an association of beta-2-agonists and inhaled corticosteroids for moderate asthma. Although most of the questioned physicians gave an appropriate treatment for moderate asthma treatment adapted to the severity of the situation, their therapeutic approach did not seem to be based upon the same criteria than that recommended in the guidelines.     

The use and effectiveness of a comparison routine in diverse secondary content classrooms.

The purpose of this investigation was to explore teachers' use and effectiveness of a comparison routine to help students understand comparisons of important content information in secondary content classes containing students of diverse ability. Various research methodologies, including single-subject and large-group experimental designs, were used. Measures included students' knowledge of information involving comparisons, the numbers and types of comparisons teachers used, teachers' use of the instructional routine, and teachers' and students' satisfaction with the instruction. Use of the routine led to significantly better retention and expression of information by students in the experimental condition compared with students participating in a traditional lecture-discussion format. Teachers easily learned the routine, delivered more complete instruction, and used the routine to teach regularly scheduled curricula. Teachers indicated that they were satisfied with the routine; in general, students were neither satisfied nor dissatisfied with the routine.

Teachers' occupational well-being and quality of instruction: The important role of self-regulatory patterns.

Teachers' occupational well-being (level of emotional exhaustion and job satisfaction) and quality of instruction are two key aspects of research on teaching that have rarely been studied together. The role of occupational engagement and resilience as two important work-related self-regulatory dimensions that predict occupational well-being and teachers' instructional performance in the classroom was investigated. In Part 1 of the study, self-regulatory data from 1,789 German mathematics teachers were subjected to a latent profile analysis, yielding four self-regulatory types (healthy-ambitious, unambitious, excessively ambitious, and resigned) that differed significantly on emotional exhaustion and job satisfaction. In Part 2, the association between teachers' self-regulatory type and instructional performance was examined in a subsample of 318 teachers. Results showed that teachers' self-regulatory type predicted the quality of instruction in three of the four aspects of instructional performance examined. Moreover, teachers' self-regulatory type was systematically linked to differences in students' motivation. No association was found between teacher self-regulation and student achievement.

The effect of temperature and humidity on dengue virus propagation in Aedes aegypti mosquitos

School children are important targets for sun awareness education, but the knowledge, attitudes and behaviour of school teachers with respect to sun awareness are poorly understood. A questionnaire-based survey of 76 school teachers was undertaken. Twenty-four per cent of teachers indicated previous experience in teaching sun awareness, but 93% of teachers had no classroom resources for teaching sun awareness. Sun awareness was perceived by respondents as unimportant relative to other health education issues. There was considerable scope for improvement in attitudes and behaviour of teachers with respect to sun awareness. Teachers need more information about environmental factors which affect strength of sunlight, individual risk factors for sunburn and sunscreen strength. Intervention strategies involving school teachers need simple messages, emphasizing the importance of shade, clothing and hats in sun avoidance.     

Resection-line involvement in gastric cancer: a continuing problem

Surgeons are aware of the adverse effect that resection-line disease has on anastomotic leakage, perioperative mortality and long-term survival. In an attempt to assess the effect of this knowledge on surgical practice, patients entered into the second British Stomach Cancer Group adjuvant therapy trial were studied. The presence of resection-line disease was compared with the operative stage. Of 555 patients for whom complete data were available, resection-line disease was present in 105 (19 per cent). Of 424 patients undergoing what the surgeon considered to be a potentially curative operation, 55 (13 per cent) had involvement of one or both resection lines, rendering the surgery palliative. Only 9 per cent of patients with stage I-III disease and resection-line involvement survived beyond 5 years, compared with 27 per cent of those with clear lines. Despite knowledge of the adverse effects of resection-line disease, surgeons continue to perform inadequate resections. This demonstrates the need for a more aggressive approach to assessment of resection margins at operation.     

The occlusal status of disabled children

The occlusal status of children in 6 schools for the handicapped was determined using the Occlusal Index (O.I.) of Summers (1966). Two dentists examined 381 children who had not previously received orthodontic treatment. An additional questionnaire investigating treatment interests and habits was also completed for each child. The study showed that 74,5 per cent required treatment, 10,5 per cent had good occlusions and 15 per cent had slight malocclusions where treatment was not considered essential. The mean O.I. was 7,92 +/- 4,33. Schools with mainly cerebral and mentally disabled children had a slightly higher O.I. but the difference in values was not statistically significant. The analysis also showed that 40,6 per cent of children were interested in receiving orthodontic treatment, but only 0,5 per cent were planning to seek it. There is a need for orthodontic treatment amongst disabled children and this should be taken into account in future oral health care planning.     

Prognostic value of dipyridamole thallium-201 screening to minimize perioperative cardiac complications in diabetics undergoing kidney or kidney-pancreas transplantation

A survey of knowledge, attitude and practice (KAP) regarding human immunodeficiency virus infection was performed on 899 students from 3 government-administered high schools located in the Bangkok Metropolitan area. Initially, all students completed a written questionnaire (pre-test) regarding HIV/AIDS. Following this, they attended a slide lecture presentation given by a specialist physician. The same test questionnaire was then completed by the same students six weeks (post-test) later for comparison of their previous KAP. The subjects composed of male to female ratio equal to that of the median age 15-16 years old. Sixty-seven per cent of the subjects were living with their parents, 16.3 per cent with relatives and 15 per cent with friends. Ninety nine per cent of the subjects had received information on HIV/AIDS before enrollment to this study. The source of knowledge ranged from television (89.1%), teachers (81.6%), pamphlets (80.2%), newspapers (75%), radio (55%), health care workers (53.4%), friends (38.6%) and only 32.5 per cent from their parents. The subjects' knowledge about HIV/AIDS and risk factors in the post-test questionnaire was significantly increased (P < 0.001) from the pre-test status. However, their attitudes to an HIV infected person were not significantly changed in the post-test questionnaire: only the "attending school" question showed significantly (P < 0.05) increased numbers of agreement. Similarly, the attitudes and practices to prevent HIV infection were not significantly (P > 0.05) different between pre-test and post-test questionnaires. The result of this study is to recommend regular school-based programs of education to increase awareness of preventive strategies for HIV/AIDS and sexually transmitted diseases.     

Immunisation practices of general practitioners in metropolitan Sydney

An anonymous postal survey of all known general practitioners in the Northern Sydney Health Area (N = 987) examined the provision of immunisation services in general practice. Questions were asked about knowledge of storage of vaccines, the ages of patients administered measles-mumps-rubella vaccine, the use of reminder systems for subsequent vaccinations and whether maternal and family health was discussed at immunisation visits. There were 394 (40 per cent) respondents. Only 30 per cent used temperature monitors in their vaccine refrigerators, and 26 per cent correctly identified the period after opening that Sabin may be used (eight hours). Forty-one percent correctly injected infants in the anterolateral aspect of the thigh and 40 per cent administered measles-mumps-rubella vaccine by the recommended age of 12 months. Forty-one percent of respondents always used visits for immunisation to discuss other issues of maternal and child health and 16 per cent used reminder systems for follow-up. Sixty-six per cent of general practitioners stated that they were more likely to review the immunisation status of adolescents routinely, compared to 55 per cent who reviewed adults and 44 per cent who reviewed senior citizens. Routine review of all three groups was carried out by 43 per cent. These results must be interpreted with caution because of low response rates, and cannot necessarily be generalised to all general practitioners providing immunisation services. Nevertheless, important deficiencies in knowledge and practice of immunisation have been identified.     

Outcome and predictors of success of biofeedback for constipation

BACKGROUND: A study was undertaken to determine outcome and to identify predictors of success for biofeedback for constipation. METHODS: Patients who had at least one biofeedback session were evaluated whether or not they completed a treatment course. Parameters assessed included use of cathartics, number of spontaneous bowel movements per week, presence of rectal pain, number of biofeedback sessions and results of anorectal physiology. RESULTS: A total of 194 patients (59 male, 135 female) of median age 71 (range 11-96) years, including 30 with concomitant rectal pain, were treated. The median number of spontaneous bowel movements per week before treatment was 0. Some 35 per cent of patients had complete success (three or more spontaneous bowel movements per week with discontinuation of cathartics), 13 per cent had partial success (fewer than three spontaneous bowel movements per week with continued use of cathartics) and 51 per cent had no improvement. Neither patient age, sex nor duration of symptoms significantly affected outcome. Only 18 per cent of patients who had between two and four sessions had complete success, compared with 44 per cent of those who had five or more (P < 0.001). A total of 63 per cent of patients who completed the treatment protocol experienced complete success, compared with 25 per cent of those who self-discharged (P < 0.0001). CONCLUSIONS: This large study indicates that the success rate of biofeedback for patients with constipation is less than previously reported. However, the success rate improves significantly after five or more sessions and is significantly related to the patient's willingness to complete treatment.     

What kind of information does the health services give to children with asthma and their parents?

Good information to families who have children with bronchial asthma is essential for treatment and in helping the family to cope. The aim of this study was to find out what kind of information the parents meant they had received, their knowledge about asthma, and what sanitary measures had been taken at home. A questionnaire was sent to all children (N = 431) who, during a five year period, were entered into the records of the Department of Paediatrics, Innherred Hospital, Norway, with the diagnosis bronchial obstruction. A selected group of 55 children and their parents were also interviewed. The results showed that the parents were not satisfied with the information they had received about the illness and about effects and side effects of the medication. Furthermore, their knowledge about these matters was not satisfactory, judged both by themselves and by the interviewer. It was more difficult to quit smoking or to stop keeping animals than to do extra cleaning at home. Few parents were informed about their possibilities of receiving financial support and about patient organisations. Only in a few cases did the health service provide the school with information on the child's disease.     

Strong preference for non-invasive prenatal diagnosis in women pregnant through intracytoplasmic sperm injection (ICSI)

Intracytoplasmic sperm injection (ICSI) is a new and most powerful technique to treat severe forms of human infertility. While the follow-up studies have not shown an increased malformation risk so far, the genetic implications of ICSI are still not fully understood. For this reason, many institutions routinely recommend or even enforce invasive prenatal tests after successful intracytoplasmic sperm injection. We have counselled 107 women pregnant through ICSI about prenatal diagnosis. Sixty-five had already received genetic counselling prior to the treatment (group 1), while 42 had not attended our clinic before (group 2). They were free to choose between invasive and non-invasive diagnosis or no prenatal tests at all. Fifty-four per cent of these patients had an indication for prenatal karyotyping or other invasive procedures independent of ICSI. Only 17 per cent of the total cohort made use of amniocentesis or fetal blood sampling, 82 per cent opted for non-invasive tests (ultrasound, serum screening), and one couple did not wish any prenatal studies. The preference for non-invasive procedures was stronger in group 1 (94 per cent) than in group 2 (65 per cent). We suggest that if patients pregnant through ICSI have the option to choose freely between invasive and non-invasive prenatal tests, they strongly favour the latter.     

Treatment of severe acute exacerbation of asthma and chronic obstructive lung disease. An interview study

A telephone survey was conducted of all the 71 Danish hospitals with the capacity to receive acutely ill medical patients. The purpose was to register treatment regimes used in acute asthma and exacerbations in chronic obstructive pulmonary disease (COPD). The house officer on duty was interviewed and questioned about the use of nebulizers, oxygen therapy, bronchodilators, steroids, theophyllins and monitoring of the patient's condition. The physician survey was supplemented by a smaller survey among emergency room nurses about nebulizing systems. The answers showed inadequate knowledge of nebulizing systems. There was a noticeable variation in the dosing of oxygen and in the dosing of bronchodilators and steroids. beta 2-agonist treatment by nebulizer differed with a factor 14 in dose. The majority of the physicians had no specific parameters for monitoring severity of disease. CONCLUSION: There is a need for improvement of the knowledge of nebulizing systems, including specific knowledge of the appropriate use of propellant gasflow and time of nebulizing for optimum performance of the used nebulizer. Divergent answers from the nurses and the physicians show the need for interdisciplinary instruction. The noticeable variation in treatment in this Danish survey displays a need for quality control in terms of concise guidelines for medical therapy in acute exacerbations of asthma and COPD and guidelines for monitoring of the response to the treatment. A suggestion for a treatment regime is proposed.     

Gonorrhoea in the asymptomatic patient: presentation and the role of contact tracing for heterosexual men and women and for homosexual men

Clinically silent gonorrhoea is the major problem in the control of the disease. Only 12 per cent of infected women reported in 1974 because of symptoms, compared with 97 per cent of infected heterosexual men and only 35 per cent of homosexual men with gonococcal proctitis alone. Homosexual men, compared with heterosexual men, had twice as many subsequent sexual contacts after infection and had a higher incidence of early syphilis. Eighty-four per cent had experienced passive anorectal intercourse. Ninety-seven per cent of men with gonococcal urethritis reported because of symptoms, but occasionally (particularly after unsuccessful treatment) urethral gonorrhoea in men may be clinically silent and even require tests of the overnight urethral secretion for diagnosis. For women, and for homosexual men who have had passive anorectal (or oral) intercourse, the indication for attendance for tests for gonorrhoea should be having run the risk, and not the presence of symptoms. Routine tests of the anorectum for gonorrhoea are essential in cases of 80 women at risk, and for most homosexual men since over 80 per cent of these men will have had passive anorectal intercourse. Because gonococcal infections following treatment-failure are often clinically silent in both women and men, symptoms cannot be relied upon to indicate such failure. Follow-up smears and cultures are always essential.     

Knowledge of asthma among parents of asthmatic children

The knowledge and attitude towards asthma, of parents, of 85 asthmatic children was assessed using a 17 item questionnaire. Results showed that 34.1% believed asthma to be contagious, 48.2% of the parents hesitated in referring to their child's illness as asthma. Other commonly held beliefs were that asthma is a life long illness (35.3%); food items are important precipitating factors for acute attacks (88.2%); mild exacerbations need to be treated with bronchodilators (6.3%); bronchodilators should be started at home before consulting a physician in case of an acute attack (61.2%); and cure of asthma is possible through modern drugs (30.6%) or through alternative systems of medicine (65%). Ninety one per cent of parents lacked an awareness of the side effects of anti-asthma medication. It is concluded that parental education through improved physician parent communication is necessary for enhancing the quality of care being provided to children with asthma, a fact also highlighted by the International Consensus Report on Management of Asthma.     

Fate of occupational asthma. A follow-up study of patients with occupational asthma due to Western Red Cedar (Thuja plicata)

Thirty-eight patients with red cedar asthma proved by inhalation provocation test were studied after they had left exposure for more than 6 months. Twenty-seven patients became asymptomatic, with normal lung function (group A). Three patients had persistent chronic bronchitis with a moderate degree of airway obstruction, probably as a result of cigarette smoking (group B1). Eight patients continued to have recurrent attacks of asthma that decreased in severity after cessation of exposure, and their symptoms were probably due to previous exposure (group B2). The effect of breathing helium on maximal expiratory flow at 50 per cent of the vital capacity was studied. All except one patient in group A were responders (change in maximal expiratory flow at 50 per cent of vital capacity greater than 30 per cent). Two patients in group B1 and 2 in group B2 were nonresponders, suggesting obstruction in the small airways. All patients with red cedar asthma demonstrated bronchial hyperreactivity to methacholine to the same extent as patients with nonoccupational asthma. This hyperreactivity persisted after they left exposure, irrespective of symptoms. It is not known at present whether bronchial hyperreactivity is the predisposing factor in occupational asthma or is the result of the disease.     

Death certification by house officers and general practitioners--practice and performance

The objective of this study was to assess the knowledge, attitudes and behaviour of House Officers and General Practitioners (GPs) in relation to death certification, to determine the scope for future intervention. A postal questionnaire was used to survey all House Officers (174) and a 10 per cent random sample of GPs (131) in Mersey Region. The main outcome measures were: death certification experience; knowledge, attitudes and behaviour in relation to data uses and coding; and acceptability of Cause of Death statements. Response rates were comparable-119/174 House Officers (68.4 per cent) and 95/131 GPs (72.5 per cent). Most House Officers (78.8 per cent) and GPs (85.3 per cent) reported that they made the best possible Cause of Death statement but, respectively, 62.4 per cent and 59.3 per cent of these might modify a statement in some circumstances. Significantly more House Officers (70.3 per cent) than GPs (44.2 per cent) acknowledge room for improvement and were amenable to more training (86.6 per cent versus 52.5 per cent), but significantly fewer felt sufficiently instructed (23.7 per cent versus 52.6 per cent). Most respondents (> 90 per cent) considered accurate death certification important, but 46.2 per cent of House Officers had not read the death certificate book instructions. Knowledge was variable, especially concerning Underlying Cause of Death. Written Cause of Death statements were broadly similar in style and standard between groups. Experience did not appear to improve death certification practice. Better and co-ordinated undergraduate and early post-graduate education (which should be continuing and audited), and practical accessible guidance on death certificate completion, might improve standards of practice and performance within the existing framework. Alternative methods of presenting guidance on death certificate completion should be explored.
