Ernst Haeckel was a very versatile and complete biologist, equally at home with imaginative leaps of conceptualization, serious natural history in the wild, and meticulous experimentation in embryology. His work shaped the development of a holistic evolutionary perspective that brought ecology, ontogeny, phylogeny, and biogeography together into a unified explanation of the patterns of diversity seen in the living world. He, along with Darwin and Mendel, was perhaps one of the three most consequential biologists of the nineteenthcentury, in many ways the golden age of biology.  相似文献

Although scholars and popular press writers are critical of school district failures to remove inadequately performing teachers, little has been said about the thinking of principals on this issue. Because principals are the front-line implementers of evaluation policy, their beliefs about barriers (real or perceived) are likely to influence their actions. This study asked elementary and middle school principals in the state of Oregon to identify barriers to deal effectively with inadequately performing teachers. Results demonstrated that principals believe teacher unions to be the most significant barrier, and blame the union representatives more often than the language of the negotiated contract. In addition, principals identify the amount of time required to engage in the process as a barrier. Continued study of principal beliefs about these factors may suggest (1) areas of needed reform in the implementation of evaluation and (2) administrative training needs.  相似文献

The aim of this paper is to present the findings of a qualitative study carried out on perceptions of high school students on the use of ICT in learning in a secondary school in Mombasa, Kenya. The study involved 18 students in the 11th grade (form three). The students took part in three focus group discussions and six one-on-one interviews over a period of 2 weeks. Several themes on the learners’ understanding of and reaction to ICT were identified. It was revealed that learners had a sound understanding of the various types of ICT and could even define them while explaining the uses of these ICT tools. Findings showed that the learners were generally motivated about using ICT and that ICT encouraged student-centered learning leading to better understanding and performance in their studies. All in all, the findings from this study indicate that learners are aware of the importance of ICT in their learning and feel that at the moment the use of ICT in school is no longer a luxury but a necessity that has taken too long to materialize.  相似文献

A recent review of research revealed that much of the advice given for writing multiple-choice test items is based on experience and wisdom rather than empirical research. The present study involved the testing of two common item-writing rules: (1) the phrasing of the stem in the form of a question versus a partial sentence and (2) the use of the inclusive “none of the above” option instead of a specific content option. Limited empirical research suggests that using the partial sentence format and the inclusive “none of these” option may lead to undesirable item and test characteristics, whereas textbook authors essentially are divided on the opinions about the validity of each rule. Results of this experimental study offer no evidence to support the use of either type of stem and limited evidence to caution against the option “none of the above.”  相似文献

The National Science Education Standards emphasize teaching unifying concepts and processes such as basic functions of living organisms, the living environment, and scale (NRC 2011). Scale includes understanding that different characteristics, properties, or relationships within a system might change as its dimensions are increased or decreased (NRC 2011). One such relationship involves surface area to volume which is a pervasive concept that can be found throughout different sciences. This concept is important for students to not only understand the association of the two, but to also be able to apply this relationship in science contexts. The purpose of this study is to investigate the factors that influence the understanding surface area to volume relationships. This study examined middle school students’, high school students’, and science teachers’ logical thinking skills (including proportional reasoning), visual-spatial skills, and understandings of surface area to volume relationships. Regression results indicated that participants’ reasoning abilities and components of visual-spatial skills could be possible predictors for one’s ability to understand surface area to volume relationships. Implications for teaching scale concepts such as surface area to volume relationships in the science classroom are discussed.  相似文献

The ability to identify individuals by voice is fundamental for communication. However, little is known about the expectations that infants hold when learning unfamiliar voices. Here, the voice-learning skills of 4- and 8-month-olds (N = 53; 29 girls, 14 boys of various ethnicities) were tested using a preferential-looking task that involved audiovisual stimuli of their mothers and other unfamiliar women. Findings reveal that the expectation that novel voices map on to novel faces emerges between 4 and 8 months of age, and that infants can retain learning of face-voice pairings via nonostensive cues by 8 months of age. This study provides new insights about infants’ use of disambiguation and fast mapping in early voice learning.  相似文献

Curricular implementations are unlikely to deliver the anticipated benefits for mathematics learners if written guidance to teachers is interpreted and enacted differently from the ways that policymakers and curriculum designers intend. One way in which this could happen is in relation to the mathematics tasks that teachers deploy in the classroom. Teachers and curriculum designers have developed an extensive vocabulary for describing tasks, using adjectives such as ‘rich’, ‘open’, ‘real-life’, ‘engaging’ and so on. But do teachers have a shared understanding of what these adjectives mean when they are applied to mathematics tasks? In study 1, we investigated teachers’ appraisals of adjectives used to describe mathematics tasks, finding that task appraisals vary on seven dimensions, which we termed engagement, demand, routineness, strangeness, inquiry, context and interactivity. In study 2, focusing on the five most prominent dimensions, we investigated whether teachers have a shared understanding of the meaning of adjectives when applied to mathematics tasks. We found that there was some agreement about inquiry and context, some disagreement about routineness and clear disagreement about engagement and demand. We conclude that at least some adjectives commonly used to describe tasks are interpreted very differently by different teachers. Implications for how tasks might be discussed meaningfully by teachers, teacher educators and curriculum designers are highlighted.  相似文献

A teacher evaluation system can be threatening to faculty, especially if used for summative decisions. Therefore, it is important to obtain valid and pertinent information. Since students are extensively exposed to course elements, students’ evaluation of instruction should be one of several components in the teacher evaluation system. Since traditional methods, such as Cronbach’s alpha and ordinary least squares regression, do not address the hierarchical data of the classroom, the current study used the statistical techniques of confirmatory factor analysis and hierarchical linear modelling in order to properly investigate the reliability and validity of the Students’ Assessment of Instruction (SAI) instrument. Use of hierarchical linear modelling to analyse teacher evaluation instruments could not be found in the literature, although it has been used in educational settings. This study will illustrate its usefulness in determining what measures are related, either as evidence of validity or as a bias, to instructional effectiveness. Student responses were also compared with faculty self-evaluations, one indicator of effective teaching, in order to determine if the SAI does measure instructional effectiveness. Overall, the SAI was found to have good reliability and validity with relatively few biases and could be used to extract five distinguishable traits of instructional effectiveness.  相似文献

With the increased requirement to incorporate counter-terrorism measures into the British education system, teachers are now expected to discuss terrorism within the classroom setting. However, this is a challenging endeavour due to the complex nature of the phenomenon, including definitional questions and links made to certain ideologies, in particular religious motivations. This paper explores my research findings from a project conducted over several years into pupils’ perceptions of terrorism and its links to religion in general, as well as the specific links made with Islam, Sikhism and Christianity. To contextualise the research, a brief overview of the methods and results has been provided, followed by an analysis of the issues raised. Overall, the pupils thought that religion in general, as well as Islam in particular, was something that motivated terrorism. However, many pupils also expressed concerns about associating entire religious communities with terrorism, perceiving it as a stereotype, and expressed interest in discovering more about how and why religion was used to justify such violent attacks.  相似文献

Students conceive of assessment in at least four major ways (i.e., assessment makes students accountable; assessment is irrelevant because it is bad or unfair; assessment improves the quality of learning; and assessment is enjoyable). A study in New Zealand of 3469 secondary school students’ conceptions of assessment used a self‐report inventory and scores from a standardised curriculum‐based assessment of reading comprehension. Four inter‐correlated conceptions based on 11 items were found with good psychometric properties. A path‐model linking the four correlated conceptions with student achievement in reading, while taking into account student ethnicity, student sex, and student year, had good psychometric properties. The conception that assessment makes students accountable loaded positively on achievement while the three other conceptions (i.e., assessment makes schools accountable, assessment is enjoyable, and assessment is ignored) had negative loadings on achievement. These findings are consistent with self‐regulation and formative assessment theories, such that students who conceive of assessment as a means of taking responsibility for their learning (i.e., assessment makes me accountable) will demonstrate increased educational outcomes.  相似文献

Attitude statements, mostly concerned with the social implications of science, were administered to 2100 pupils of age 14+. The sample was divided into the top 25oO ('GCE') and the next 30‐40oo ('REST') of the ability range and further divided by sex and by coeducation and single‐sex education.

Factor analysis yielded measures of five independent attitudes to (1) science as a school subject (SUBATT) and to its implications (SOCATT) regarding (2) aesthetic/humanitarian issues; (3) practical benefits (4) value to the state for money invested (S) the activities of scientists. The attitude scores were correlated with the biology, chemistry and physics choices made at this age and with liking for these subjects’ teachers. There were 26/60 significant but low overall correlations with physics and chemistry choices, but only 5/30 for biology. A further 26 significant correlations arose either at high or low teacher liking, the former predominating with boys and the latter with girls.

A Kruskal‐Wallis analysis indicated that some attitudes in the ‘GCE’ group were unaffected by the school attended and possibly derived from the media. Adverse attitudes to the social implications of science may be a factor in the swing away from physical science and technology.  相似文献

Change across wider English society in the 1960s was characterised by a managed and relatively consensual social liberalism. There was a discernible cultural shift toward greater personal and sexual freedom. Within education in England, a revisionist approach sought to extend traditional education to a wider constituency, in particular incorporating the sometimes disaffected and unskilled working class. This context presented new challenges for 1960s teachers in their relationships with pupils. Through the 1950s and 1960s, English cinema portrayed England’s changing teacher–pupil relations. This article examines the nature of change in teacher–pupil relations, with particular regard to its impact upon teachers’ authority. English cinema’s representation is located within English societal change in the 1960s in relation to youth culture, education and attitudes to authority.

Several themes are identified. Teacher status appeared to contribute rather less to 1960s teachers’ authority and teachers’ personalities rather more. 1960s teacher–pupil relations were somewhat volatile. Relationships began to take place beyond the school gates. Films depicted greater diversity in teachers’ strategies to maintain their authority, with some teachers making concessions to pupils to preserve harmonious relations. A more prominent approach was teachers’ still more firm imposition of traditional discipline, attempting to hold back the tide of increased pupil hostility in classrooms, which more frequently featured the particular challenges posed by girls.

The analysis has relevance beyond England and beyond the 1960s. It explores the variety and fragility of teacher authority, highlights the pressure that maintaining discipline places upon individual teachers and recognises the appeal of classroom conservatism.  相似文献

The Campaign for Learning’s Learning to Learn Phase 4 was a research project in which teachers undertook practitioner enquiry to explore innovative pedagogies under the umbrella term of learning to learn. In 2008, to gain greater understanding of what this process meant to the participating teachers the research team at Newcastle University undertook narrative interviews which examined three key areas: the motivation for undertaking practitioner enquiry, the experience for both teachers and students, and the support needed to facilitate success. This paper examines how the decision to use narrative interviews in conjunction with an iterative validation process supported a meaningful and ethical exchange between the teachers and researchers, where knowledge generation was foregrounded, and how despite each teacher producing a unique, highly contextual story, cross-narrative themes emerged which have enabled the research team to broaden our understanding of practitioner enquiry.  相似文献
