The aim of this study was to provide a better understanding of the main difficulties hindering undergraduate biology students in learning histology. The study utilized a self-administered questionnaire which included three closed-ended and two open-ended questions: (1) if students had difficulty in learning about each tissue type; (2) what might be the problem in learning about the tissue at hand; (3) which topics were the most difficult; (4) what were the possible reasons that made image identification of tissue types difficult; and (5) how to improve the course curriculum from a student perspective. The survey was administered to 139 undergraduate biology students enrolled in a histology course, of which 101 surveys were completed and analyzed both qualitatively and quantitatively. The topics that students experienced the most difficulties with were: nervous tissue, plant tissues, bone tissues, and glandular epithelial tissue. The main reasons students experienced difficulties with these tissue types, according to the students themselves, were the nature of the topic, grasping the terminology used, and insufficient teaching time. Students suggested the adoption of strategies such as: teaching based on practical tasks; reducing the content of the histology curriculum; adding anatomy subjects; and making histology education more interesting.  相似文献

The study aimed to investigate how students in an introductory educational sciences course experienced and understood their own actorship during the course, in relation to conditions for learning created by the teachers. The analyses were based on students’ answers to an evaluation questionnaire that produced both quantitative and qualitative data. Those students who experienced opportunities to influence the course activities also stated that they had contributed to the development of the course to a greater extent than did those who experienced no such opportunities. There was no correlation between not feeling informed about the conditions for the course and seeking complementary information. The analysis also generated five different categories based on how the students viewed their own actorship, varying from ‘no actorship since it is not meaningful’ to ‘Real actorship exists’. The results are discussed in relation to methodological reflections and as implications for increasing students’ actorship.  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

Internet offers people with intellectual disabilities (ID) unique opportunities to access information and to participate in society. But concerns have been raised about the potential risks they face when accessing the Internet (e.g. giving credit to false information, being exposed to manipulative content). As part of the current debate between positive risk-taking and overprotection, our study empirically tested the extent to which 43 adults with ID identified and selected topically relevant as well as trustworthy web pages while searching the Internet for several topics (e.g. Can social networks use your pictures for advertisement?). Participants also justified their search decisions. Results revealed that while searching familiar topics (i.e. social networks), participants selected more relevant and trustworthy pages than irrelevant and less trustworthy ones. Searches of less familiar topics (i.e. daily health), were carried out randomly, that is, without applying a specific criterion. Results point to the importance of topic familiarity on people’s with ID performance on Internet searching tasks. This pattern of results suggests that, first, we should avoid overprotection when people with ID search for familiar topics and, second, they need more support when searching for information about less familiar topics.  相似文献

This paper deals with the topic of child protection in Irish primary schools, and reports on a recently completed survey of newly qualified teachers’ knowledge of and familiarity with their school's child protection policies and procedures. The study was undertaken by means of a questionnaire survey, and conducted with 103 teachers from different schools. The child protection roles and responsibilities of schools are clearly spelt out in national guidelines. However, the findings from this research indicate that compliance with the requirement to inform new staff about the guidelines and ensure that they have read them is weak. This is evidenced by the data concerning the teachers’ reported knowledge of, and familiarity with, their school's child protection policies. Half of the respondents did not know if their school had a child protection policy or not. Of those who were aware of their school's child protection policy, only just over half had read it. Well under half of the respondents knew if there was a Designated Liaison Person (DLP) with responsibility for child protection in their school. Furthermore, nearly two-thirds of respondents reported uncertainty or lack of confidence in being able to identify suspected child abuse. The paper draws on international research on child protection in education to provide the context for a discussion on the factors that influence schools’ motivation and willingness to collaborate as key protectors of children's safety and welfare, and makes recommendations for policy makers, school managers and frontline staff.  相似文献

The last year of a National Science Foundation (NSF) funded scholarship program was used to provide pseudo-formal peer mentoring activities to engineering, mathematics, and science undergraduates. A one-credit class was used to afford time for peer mentors and mentees to interact. During the fall semester, seniors augmented each week’s topics with personal experiences as to how they used the skill/topic that they had learned in their freshmen class in a future sophomore, junior or senior level course or on their co-op assignment. The last 10 min of every class were used for the seniors and freshmen to have an informal discussion. During the spring semester, the seniors served as an additional technical resource for the freshmen as they completed their class project. All participants found the one-credit class, project and peer mentoring activities beneficial to their education and would highly recommend the experience to incoming students.  相似文献

This study focused on teachers’ transfer of a variety of teaching methods from a teaching module on nanotechnology, which is an example of a topic outside the science curriculum, to teaching topics that are part of the chemistry curriculum. Nanotechnology is outside the science curriculum, but it was used in this study as a means to carry out a change in the way chemistry teachers teach. The participants in the study included nine high school in-service chemistry teachers. Three research tools were used: (1) semistructured interviews that were conducted with the teachers, after they had finished teaching their nanotechnology module, and follow-up semistructured interviews that were conducted 2 years after the teachers had taught the nanotechnology module , and teachers’ assessment and evaluation of their own teaching method, determining how the nanotechnology modules influenced the students who learned according to this program. The data collection process continued for 5 years. Most of the teachers indicated that they continued teaching the nanotechnology module that they designed and all of them stated that they integrated the unique teaching methods into their teaching of chemistry. High efficacy beliefs were built based on the self-evaluation process that was part of the teachers’ professional development program. Teaching self-efficacy beliefs and organization efficacy beliefs was found to contribute to teachers’ sustainable changes. The findings in the current research are only limited to the topic of nanotechnology; however, we believe that similar results can be obtained for any modern scientific topic that is outside the high school science curriculum. We suggest that more research should be done to determine whether the same findings emerge by using the same approach but on another topic.  相似文献

The primary objective was to investigate the effect of an important motivational variable — interest ∶ on sixth-grade children’s performance on a writing task. Because our previous research showed that prior knowledge has an inordinate effect on writing, we augmented the children’s knowledge of the topics they were to write about. Students studied one of four texts (two high-interest/moderate-knowledge and two low-interest/high-knowledge) and then were assigned to either a tutorial condition, in which they studied and wrote about the same topic, or a control condition, in which they studied one topic and wrote about a companion topic at the same interest and knowledge level. Our general expectation, that children writing with tutorial support on high-interest topics would do better than all other groups because of the motivational effect, was not supported. The results unexpectedly showed that low-interest topics supported by tutorials resulted in longer productions. In addition high interest topics facilitated only better quality ideas, but not qualitatively better writing. These results indicate that the motivational power of generally interesting topics in writing is confounded with the role of prior knowledge. It is further suggested that attentional factors may explain why topic interest has a limited effect on children’s writing performance.  相似文献

The present research addressed the issue of ‘life after a course’. The study aimed to evaluate the efficacy of four in‐service teacher‐training courses at the Hong Kong Institute of Education in terms of their usefulness and relevance to the teachers’ needs on return to school. An end‐of‐course evaluation questionnaire and a follow‐up questionnaire were sent six months after the courses to see if there were any significant differences in the participants’ views on the effectiveness of a course at two different time points. Qualitative data collected from interviews between the tutors and participants six months after the courses were also analysed to find out which aspects of the courses were considered to be most useful to the teachers on their return to school, and why they were useful. The findings from the research give valuable insights into the design of teacher‐education courses.  相似文献

This paper studies the teacher perceived applicability of historical topics for interpretational history teaching and the criteria teachers use to evaluate this applicability. For this study, 15 expert history teachers in the Netherlands striving for interpretational history teaching were purposefully selected. Teachers were asked to mention historical topics using a ranking task technique to rank topics in order of applicability and to elaborate on how the topics were ranked. The results showed a large variation in perceived applicability among topics, both within and between teachers. Eight different topic-applicability criteria were discerned in the teachers’ elaborations: (1) topic knowledge; (2) topic affinity; (3) topic constructedness; (4) topic deconstructability; (5) topic abstractedness; (6) topic sensitivity; (7) topic materials; and (8) topic inclusion in the history curriculum. We found that teachers tended to judge topics as applicable for interpretational history teaching partly depending on the degree of ‘canonised interpretativity’ in lesson materials and the curriculum, and to the degree to which they belonged to ‘cold’ (morally neutral) or ‘hot’ (morally sensitive) history. A theoretical implication of the findings is that interpretational history teaching is topic-dependent. Teachers can be supported to teach history as interpretation by structured pedagogies.  相似文献

Professors and teachers were compared relative to their perspectives on preservice educational measurement courses. Twenty-four professors from different colleges in seven states and 360 teachers from elementary and secondary schools in one midwestern state responded via mailed questionnaire. Professors reported the emphasis given to each of eight topics in preservice educational measurement courses, and teachers reported the emphasis they believed should be given to each topic. In five of the eight content areas, the relative emphases given by professors differed from that recommended by teachers. Major differences emerged in nontest evaluation, statistical analysis, and formative and summative evaluation. Implications of these results are discussed.  相似文献

A study was conducted to quantify the effectiveness of concept maps in learning physics in engineering degrees. The following research question was posed: What was the difference in learning results from the use of concept maps to study a particular topic in an engineering course? The study design was quasi-experimental and used a post-test as a measuring instrument. The sample included 114 university students from the School of Industrial Engineering who were divided into two equivalent homogeneous groups of 57 students each. The amount of learning attained by the students in each group was compared, with the independent variable being the teaching method; the experimental group (E.G.) used concept maps, while the control group (C.G.) did not. We performed a crossover study with the two groups of students, with one group acting as the E.G. for the topic of optical fibers and as the C.G. for the topic of the fundamental particles of matter and vice versa for the other group. For each of the two topics studied, the evaluation instrument was a test of 100 dichotomous items. The resulting data were subjected to a comparative statistical analysis, which revealed a significant difference in the amount of learning attained by the E.G. students as compared with the C.G. students. The results allow us to state that for the use of concept maps, the average increment in the E.G. students’ learning was greater than 19 percentage points.  相似文献

In the past few years, science educators and the nation at large have become increasingly concerned about the “Crisis in Science Education.” An underlying cause of this crisis is the nonuniform quality of instruction delivered by secondary science teachers. One way to improve the quality of teaching in the schools is the application of science education research findings to teaching. Most teachers are unaware of the research findings and/or do not apply them in their classrooms. This study helps determine the areas of research which are of greatest interest to secondary science teachers. Results will be used by NSTA to determine the contents of future volumes of the monograph What Research Says to the Science Teacher. A random sample of 600 secondary science teachers was obtained from the National Registry of NSTA. Teachers were sent a 23 item questionnaire that asked them to rate their interest in each research topic on a five point scale. The questionnaire contained the 12 items prepared by a NARST-NSTA committee in 1979 and an additional 11 items using the same format. Demographic data collected from the survey included sex, teaching assignment, role in school, type of school, type of community, years of teaching experience, and familiarity with What Research Says. … Data were analyzed using this demographic data as well as according to whether teachers returned the original or a follow-up questionnaire. Teachers who returned the first questionnaire had basically the same preferences as those who returned the follow-up questionnaire. Sixty percent of the teachers completed the questionnaire in usable form. Overall results of the study based on both frequency of response and on mean rating indicate that the following five topics are of greatest interest to secondary science teachers: laboratory experiences, motivational techniques, effect on college courses, problem solving, and meaningful learning. Analysis of data according to the subject taught indicated that chemistry and physics teachers are more interested in problem solving than biology teachers, and that chemistry, physics, and earth science teachers are also interested in the sequence of the content. Males and females had the same top five interests but in a different order. The same is true for teachers of grades 7–9 versus grades 10–12. Rural teachers preferences varied substantially from those in other settings and differences were also found for teachers familiar with What Research Says … compared to the rest of the sample. For every classification of teacher, the area of least interest was sex difference research.  相似文献

The integrative role that Evolutionary theory plays within Biology is recognised by most scientific authors, as well as in governmental education policies, including Brazilian policies. However, teaching and learning evolution seems problematic in many countries, and Brazil is among those. Many factors may affect teachers’ and students’ perceptions towards evolution, and studies can help to reveal those factors. We used a conceptual questionnaire, the Measure of Acceptance of the Theory of Evolution (MATE) instrument, and a Knowledge test to assess (1) the level of acceptance and understanding of 23 undergraduate Biology students nearing the end of their course, (2) other factors that could affect these levels, including course structure, and (3) the most difficult topics regarding evolutionary biology. The results of this study showed that the students, on average, had a ‘Very High Acceptance’ (89.91) and a ‘Very Low Knowledge’ (59.42%) of Evolutionary theory, and also indicated a moderate positive correlation between the two (r?=?0.66, p?=?.001). The most difficult topics were related to the definition of evolution and dating techniques. We believe that the present study provides evidence for policymakers to reformulate current school and university curricula in order to improve the teachers’ acceptance and understanding of evolution and other biological concepts, consequently, helping students reduce their misconceptions related to evolutionary biology.  相似文献

This study investigated the relationship between problem familiarity and students’ learning in a problem-based course. Problem familiarity in this study refers to the extent to which a problem fits with students’ prior knowledge and experiences. As part of regular course work, 172 students were given two problems on different occasions. These problems varied in the extent of problem familiarity. Students’ report of their learning activities and tutor’s assessment of the students’ learning were collected at the end of the problems. Results showed that both the students and tutors found the familiar problem to be better for learning. However, some elements of unfamiliarity may not be all that bad. For instance, unfamiliarity may result in more questioning, thinking and reasoning. However, this did not contribute to significant difference in terms of overall critical reasoning. Results also indicated a need to closely examine students’ critical reasoning (in terms of evaluating multiple perspectives) and students’ collaborative learning (in terms of brainstorming and discussion) when given familiar/unfamiliar problems.  相似文献

Learners may increasingly encounter conflicting expert reports. However, little is known about how they deal with this challenge. We examined how learners' familiarity with a controversial historical topic affects their epistemic judgments of conflicting expert claims and sources, the interplay of their claim and source evaluation strategies, and their meta-epistemic understanding of the legitimacy of the disagreement (absolutist, multiplist, and evaluativist perspectives). In two studies, topic familiarity increased agreement with belief-consistent expert claims and the perceived trustworthiness of the expert who presented these claims. Topic familiarity also impacted the coordination of evaluation strategies and led to greater reliance on knowledge-based validation. However, topic familiarity did not affect meta-epistemic understanding of the legitimacy of the controversy. In the second study, reading an explanation about reasons for disagreements between historians resulted in higher evaluativism. Teaching about expert disagreement may be a productive approach for promoting appreciation of the diversity of knowledge.  相似文献

ABSTRACT

Despite a growing number of Second Language (L2) researchers working in cross-cultural and cross-linguistic settings, issues related to these uniquely situated researcher identities have only scantily been addressed. In order to close this gap, we investigated three U.S.-based Korean female researchers in L2 studies. We sought to understand (1) the ways in which these researchers chose research topics, contexts, and participants; (2) how they related themselves to their research participants; and (3) to what extent and how they negotiated identities in conducting and reporting their research. With theoretical frameworks of positionality and intersectionality of researcher identities, we drew upon a few salient points from multiple data sources such as interviews, published papers, and field notes. We found not only that their research interests stemmed from their life experiences and graduate training, but accessibility, familiarity, and researcher’s self-identification also influenced their research topics, contexts, and relationships with their research participants. Furthermore, researchers’ active positioning themselves in relation to research content, contexts, and participants using their intersecting identities proved to be beneficial to their research. What our findings further suggest is that researchers embrace hybridity and multiplicity of subjectivities and identities in order to make a fair contribution to knowledge construction.  相似文献

A survey was carried out among all ex‐B.Ed. (Hons) students who are currently teaching in Maltese state primary and secondary schools to investigate the relevance and interest of the topics covered in the educational psychology and human development area of the course. Using a postal questionnaire, 183 respondents (55 per cent of the population) rated each of 45 topics on a five‐point scale in terms of interest and relevance. The t‐test analyses revealed statistical significance in the difference between the mean interest and relevance ratings for the majority of the topics. The relevance of each topic for the primary and the secondary school teacher was also investigated; in only 9 topics was the difference in the ratings for relevance statistically significant. The implications of the findings for the revision of the syllabus are outlined.  相似文献

A category learning judgment (CLJ) involves judging one’s learning or performance for a given topic or category. The present study was the first to investigate CLJs in a classroom, where students’ judgments of how well they have learned topics may be particularly relevant for guiding their study decisions. In an undergraduate statistics class, students predicted their performance on six different exam topics, as well as predicting their global exam performance, for each exam during the semester. Regarding the absolute accuracy of CLJs, we observed slight overestimation (bias), substantial deviation from accuracy (absolute bias), and little improvement across exams. Students’ CLJs varied among topics, but they were less variable than actual topic performance and were poor at discriminating well-learned from poorly-learned topics (i.e., low relative accuracy). We examined two factors predictive of CLJ accuracy: topic difficulty and student mastery of the topics. Regarding topic difficulty, a hard-easy effect was observed, such that more difficult topics produced greater overestimation and easier topics produced more underestimation. A hard-easy effect also extended to absolute bias: difficult topics produced larger deviations from accuracy than easy topics did. Regarding student mastery of topics, we found that lower mastery predicted CLJ overestimation and higher mastery predicted CLJ underestimation. Lower mastery was also associated with larger absolute bias. Compared to global judgments, CLJs were less accurate, although students were more confident in their CLJs. In sum, developing methods to improve the accuracy of CLJs in classrooms is an important direction for future research.  相似文献

《Assessing Writing》2008,13(2):93-110
Writing performance is greatly affected by task-related elements such as topic familiarity, difficulty, task-type, and subject matter of the prompt, which are perceived differently by each individual writer. Yet, little has been reported on the direct relationship between writers’ perceptions of a prompt and their actual performance on the prompt. The present study explored possible associations between students’ perceptions of a writing prompt and their actual writing performance on a field-specific (FS) English for academic purposes (EAP) writing test, compared to those on a general-topic test. Each of the 124 students produced two writing samples, one on an assigned regular topic and the other on one chosen from the four FS prompts. The writers also responded to a survey of their perceptions of the FS prompts and the FS test in general. The subjects’ performances on the two tests were compared across the four prompt subgroups, and analyzed against their survey responses. It was found that students’ performances were not statistically different on the two different tests or across the prompts chosen on the FS EAP writing test. Further analysis revealed that student subgroups varied in their perceptions of the degree of prompt familiarity. Based on the results, future research implications are proposed for EAP testing and L2 writing research.  相似文献
