Researchers have found that teacher preparation programs are not universally preparing teacher candidates in concepts associated with the alphabetic principle. Yet, the majority of students with reading disabilities or who struggle with beginning reading have difficulty with phonology and concepts associated with the alphabetic principle. The purpose of this study was to examine the efficacy of a series of multimedia modules on participants' (N = 76) knowledge and skills related to early reading instruction. The multimedia modules covered basic literacy concepts primarily related to phonology and phonics. Results from the experimental, control-group design indicated that the modules were successful in teaching foundational literacy constructs to participants. Thus, multimedia modules may be a promising avenue for providing instruction for teacher candidates. Additional research, however, is needed to ensure mastery of knowledge and to evaluate how principles of effective instruction can guide multimedia module use by teacher educators. 相似文献

The primary aim of this study was to investigate whether and, if so, how formal teacher competence relates to the relationship between pupil reading achievement and teachers judgements’ of pupils’ reading achievement. The data come from the Swedish participation in the Progress in International Reading Literacy Study (PIRLS) 2001 in Grade 3. Information was obtained from pupils (N = 5271) and teachers (N = 351). Analyses were conducted using multilevel structural equation modeling (SEM) with random slopes. Teacher competence was operationalized using multiple observed indicators and defined as a latent variable. A higher correspondence between teacher judgements and pupil reading achievement for teachers with higher competence was found. The results highlight the importance of teacher competence in assessment practice. 相似文献

Science educators, historians of science and their students often share a curiosity about historical instruments as a tangible link between past and present practices in the sciences. We less often integrate instruments into our research and pedagogy, considering artefact study as the domain of museum specialists. We argue here that scholars and teachers new to material culture can readily use artefacts to reveal rich and complex networks of narratives. We illustrate this point by describing our own lay encounter with an artefact turned over for our analysis during a week-long workshop at the Canada Science and Technology Museum. The text explains how elements as disparate as the military appearance of the instrument, the crest stamped on its body, the manipulation of its telescopes, or a luggage tag revealed the object’s scientific and political significance in different national contexts. In this way, the presence of the instrument in the classroom vividly conveyed the nature of geophysics as a field practice and an international science, and illuminated relationships between pure and applied science for early twentieth century geologists. We conclude that artefact study can be an unexpectedly powerful and accessible tool in the study of science, making visible the connections between past and present, laboratory and field, texts and instruments. 相似文献

This paper synthesizes findings from three studies to answer a general question: What do casual, adult visitors learn about science from their science‐related experiences in free‐choice settings? Specifically we asked whether there are changes in how people think about science in their daily lives, the nature and use of scientific knowledge, and its communication by scientists. The three studies involved samples of visitors to an interactive science centre, visitors to a traditional natural history museum, and attendees at a series of public lectures, each given by an expert scientist in human genetics. Pretest and post‐test data collected by parallel questionnaires indicated that, despite the different nature of their experience in the three different settings, participants became more positive about the value of science and the work done by scientists and their ability to communicate with the public. At all venues, however, participants became less scientific in their thinking about the nature of scientific knowledge, becoming more likely to believe it to be infallible. The consistency of these findings was surprising, and participants’ changed views about the nature of scientific knowledge were unexpected. Possible explanations for theses outcomes were suggested in terms of participants’ reasons for attending the venue, the nature of their engagement, and the non‐controversial ways in which the exhibitions and lectures were structured. The findings suggest that the educational role of free‐choice settings should be considered carefully, particularly with regard to the representation of science. 相似文献

Educational researchers and teachers are well aware that misconceptions—erroneous ideas that differ from the scientifically accepted ones—are very common amongst students. Daily experiences, creative and perceptive thinking and science textbooks give rise to students' misconceptions which lead them to draw erroneous conclusions that become strongly attached to their views and somehow affect subsequent learning. The main scope of this study was to understand what students consider a mineral to be and why. Therefore, the goals were (1) to identify eleventh-grade students' misconceptions about the mineral concept; (2) to understand which variables (gender, parents' education level and attitude towards science) influenced students' conceptions; and (3) to create teaching tools for the prevention of misconceptions. In order to achieve these goals, a diagnostic instrument (DI), constituted of a two-tier diagnostic test and a Science Attitude Questionnaire, was developed to be used with a sample of 89 twelfth-grade students from five schools located in central Portugal. As far as we know, this is the first DI developed for the analysis of misconceptions about the mineral concept. Data analysis allows us to conclude that students had serious difficulties in understanding the mineral concept, having easily formed misconceptions. The variables gender and parents' education level influence certain students' conceptions. This study provides a valuable basis for reflection on teaching and learning strategies, especially on this particular theme. 相似文献

Based on the teachers’ lectures and evaluations we elaborate on a model of the aspects of learning. Inside the framework of this model three ways for solving a given problem relating to the previous teaching are presented. We describe and analyse a method which is useful in selecting an evaluation task adapted to intended objectives, helps in the interpretation of the students’ performances and acts as a guide to the possible inferences about what the students acquire. 相似文献

ABSTRACTThe understanding of what makes a question difficult is a crucial concern in assessment. To study the difficulty of test questions, we focus on the case of PISA, which assesses to what degree 15-year-old students have acquired knowledge and skills essential for full participation in society. Our research question is to identify PISA science item characteristics that could influence the item’s proficiency level. It is based on an a-priori item analysis and a statistical analysis. Results show that only the cognitive complexity and the format out of the different characteristics of PISA science items determined in our a-priori analysis have an explanatory power on an item’s proficiency levels. The proficiency level cannot be explained by the dependence/independence of the information provided in the unit and/or item introduction and the competence. We conclude that in PISA, it appears possible to anticipate a high proficiency level, that is, students’ low scores for items displaying a high cognitive complexity. In the case of a middle or low cognitive complexity level item, the cognitive complexity level is not sufficient to predict item difficulty. Other characteristics play a crucial role in item difficulty. We discuss anticipating the difficulties in assessment in a broader perspective. 相似文献

This study investigated plant and animal photographs in elementary science textbooks to discern whether there were disparities in the number of plant and animal photographs or in how those photographs were labelled. We examined the Life Science sections of two nationally syndicated (USA) textbook series. For each text, we identified the photographs with plant and/or animal content and evaluated them for two features: (1) the subject of the photograph, and (2) the specificity of the label (name) provided. We found that photographs with animal subjects were more numerous than those with plant subjects; they also represented a greater diversity of animals and had a higher instance of repetition than did plant photographs. We also found a significant naming disparity: animal photographs were three times more likely to be provided with a specific label (common name) than were plant photographs. Not only were plant photographs less likely to be provided with a specific name for the plant (e.g. orchid or dandelion), but also they were commonly identified only by the name for a plant part (such as flower or leaf) or life‐form (e.g. tree or shrub). To address the disparity revealed by this study, and to encourage student interest in and knowledge about plants, we recommend that educators go beyond textbooks to expose students to a diversity of named plants, and present plants as distinct organisms rather than as a collection of parts. 相似文献

ABSTRACTStudents in senior pre-university education encounter difficulties in the application of mathematics into physics. This paper presents the outcome of an explorative qualitative study of teachers’ beliefs about improving the transfer of algebraic skills from mathematics into physics. We interviewed 10 mathematics and 10 physics teachers using a semi-structured questionnaire that was based on an algebraic transfer problem. Almost all teachers acknowledged this transfer problem and considered it to be important. We found a continuum of teachers’ beliefs about aspects influencing transfer, including beliefs on improving this transfer. Together with identified improvement aspects about coherent mathematics education, these may help reduce physics teachers’ frustrations who spend extra time on re-teaching mathematics. Teachers think that transfer does not happen, because students see both subjects as separate disciplines. Contrary to most physics teachers, most mathematics teachers do not feel the need to collaborate with physics teachers. We found two extreme, opposite beliefs about the transfer of algebraic skills into physics. An intermediate group believes that only an integrated approach can solve the transfer problem. Some of the teachers’ beliefs could be organised into a beliefs system. Further research could investigate to which extent such beliefs systems exist and which beliefs these contain. 相似文献
