In studying on-line communities, researchers must consider the unique environmental factors involved in order to minimize potential harm to human subjects. In particular, the often commented upon disinhibiting effect of computer-mediated communication can encourage people to agree to or even insist on a kind of public exposure by which they may eventually be harmed. On the Internet, where perceptions of interpersonal affect and effects may be obscured by the nature of the medium itself, care must be taken to guard against not only any increased tendency for researchers to objectify subjects, but also the tendency for subjects to underestimate the potential consequences of consent. The criteria for informed consent that may be sufficient in face-toface research environments are not necessarily so in a medium in which subjective experience is easily objectified and information is easily devalued. 相似文献
Environmental education in schools is an important strategy in achieving environmental improvement. However, it needs to be based on children's understandings of environment rather than on assumptions of what children know and believe. This paper reports on a research project where school children's answers to a question 'I think the term/word environment means ' were analysed using the qualitative research method of phenomenography. Six distinct conceptions were isolated, ranging from the least sophisticated--environment as a place--to the most inclusive and expansive--environment and people in a relationship of mutual sustainability. An important qualitative difference was found between conceptions that treat the environment as an object and relational conceptions. The implications of these findings for environmental education are discussed. 相似文献
OBJECTIVE: The primary goal of the present research was to determine whether retrospective reports of childhood disciplinary experiences and perceptions of that discipline correspond to actual childhood events and whether the accuracy of that report was influenced by the affective state of the respondent. METHOD: Eighty-three adolescent and young adult males completed a retrospective measure of physical child maltreatment, Assessing Environments (AEIII), and the Brief Symptom Inventory (BSI). As children the participants had been observed naturalistically in their homes interacting with their parents an average of 10 years earlier. RESULTS: Analyses were consistent with the hypothesis that both current mood and actual observations of parent-child interactions during childhood predict self-reported recollections of childhood maltreatment by one's parents. Further the veridicality of such recollections appears to depend upon the objective specificity versus the perceptive nature of the questions used to elicit the recollections. CONCLUSIONS: The findings suggest that assessment instruments suitable for obtaining information regarding earlier childhood victimization must utilize behaviorally specific items. Thus, items that are either global or intimate a normative comparison should be avoided. 相似文献
Entirely predictable examinations are ones for which the questions are known in advance. Some assessments are designed this way, but in public examinations, predictability is subtler. Students familiarise themselves with the requirements broadly: likely topics that will come up, question formats and how to maximise their marks. If students can predict what they have to do, they can memorise performances, such as essays, and restrict their learning to fit only with examination requirements. The danger is that this focus could undermine curriculum aims. Further, examinations that are overly predictable might produce results that do not generalise to other performances or have predictive validity. This paper presents part of a broader project investigating whether the Higher Level Irish Leaving Certificate (LC) examinations were too predictable. Here, the development of a rating scale for students’ views of examination predictability is described. Data were collected from 1002 Irish LC students taking higher level examinations in biology (n?=?536), English (n?=?749) and geography (n?=?387). Students’ views on predictability of the examination could be grouped consistently across subject areas into three factors: valuable learning, predictability and narrowing of the curriculum. Belief that narrowing of the curriculum was a good examination preparation tactic had a negative relationship with examination scores and perceived learning value of examinations was positively associated with students’ scores in biology and English. These findings indicate that the scoring system rewards students who believe they must study the discipline broadly. 相似文献
Predicting item difficulty is highly important in education for both teachers and item writers. Despite identifying a large number of explanatory variables, predicting item difficulty remains a challenge in educational assessment with empirical attempts rarely exceeding 25% of variance explained.
This paper analyses 216 science items of key stage 2 tests which are national sampling assessments administered to 11 year olds in England. Potential predictors (topic, subtopic, concept, question type, nature of stimulus, depth of knowledge and linguistic variables) were considered in the analysis. Coding frameworks employed in similar studies were adapted and employed by two coders to independently rate items. Linguistic demands were gauged using a computational linguistic facility. The stepwise regression models predicted 23% of the variance with extended constructed questions and photos being the main predictors of item difficulty.
While a substantial part of unexplained variance could be attributed to the unpredictable interaction of variables, we argue that progress in this area requires improvement in the theories and the methods employed. Future research needs to be centred on improving coding frameworks as well as developing systematic training protocols for coders. These technical advances would pave the way to improved task design and reduced development costs of assessments. 相似文献
In this paper, we reflect on a study in Brazil’s Cerrado that attempts to address a lack of attention to an aesthetic dimension in environmental education practice and research. We start by tracing this lack to the overvaluing of the cognitive sphere in the educational process, noting its echo in the low aesthetic value attributed to the Cerrado biome. Then, through reflecting on an empirical, interview based study of sensations, perceptions and feelings evoked by aesthetic experiences in the Cerrado, we draw on insights from a hermeneutic phenomenological approach to identify key themes for environmental education research and practice in this regard. These include: recognising the singularity of experience; attending to the qualities of experience; acknowledging the value/s of ‘lighter’ and ‘darker’ experiences; and deepening emotions and verbal communication. In our final considerations, we discuss the limitations of the study, alongside new directions in studies of perception, experience, aesthetics and pedagogy that may also advance attention to an aesthetic dimension in environmental education practice and research. 相似文献
Culturally diverse books are written for children to promote acceptance of diversity; however, there is little research that has examined their use. The purpose of this study was to examine the culturally diverse book use of preschoolers in daycare. Research Findings. Thirty-five children (ages 44-65 months) and their teachers in two daycare classrooms participated. The children represented a variety of socioeconomic levels and raciaVcultura1 groups. Observations of book use were conducted during freeplay and naptime. In a multiple baseline time series experimental design, comparisons were made between the use of culturally diverse books and books depicting no cultural diversity (Euro-American books). It was determined that one category of culturally diverse books (Culturally Conscious) was not being used as frequently as others. The Culturally Conscious books depicted characters from one of three cultural groups—Black, Asian, and Latino. A simple intervention was implemented in which the teachers introduced some of the Culturally Conscious books at group times and this led to an increase in their use. Additional book use information was gained through parent questionnaires, teacher interviews, and teachers' anecdotal notes. Implications for Practice. In daycare centers similar to the ones used in this study, it is likely that children will use culturally diverse books when available. Teacher introductions of infrequently used culturally diverse books may be an efficient and effective practice for encouraging their use. 相似文献
