Block scheduled versus traditional biology teaching—an educational experiment using the water lily     

Christoph Randler  Konstanze Kranich  Monika Eisele 《Instructional Science》2008,36(1):17-25

In this study, we compared a traditional teaching sequence (four distinct lessons) with a block schedule dealing with the ecological adaptations of the water lily. The educational unit contained original plant material and both experimental groups received the same tasks and working sheets. Pupils worked together in groups of three to four pupils in a self-regulated manner, carrying out hands-on experiments. However, both groups differed in their time schedule (four distinct lessons of 45 min versus one block of 180 min). Pupils from the traditionally scheduled education performed significantly better in the immediate post-test while these differences merged in retention.  相似文献   

Diagnostic and prognostic value of the urinary excretion of beta-aminoisobutyric acid in patients with urinary bladder cancer     

R. L. Gupta  K. Ramachandran  Monika  J. S. Chowhan 《Indian journal of clinical biochemistry : IJCB》1996,11(1):59-61

Urinary excretion of beta-aminoisobutyric acid (BAIB), was determined in 28 active and 12 inactive bladder cancer patients. Mean excretion of BAIB was higher in active cancer patients-187.8 mg/24 hours whereas it was 120.4 mg/24 hours in inactive cancer patients. The increased BAIB excretion in both disease groups was independent of tumour stage. BAIB appears to be a useful diagnositic aid in the assessment of bladder cancer patients.  相似文献   

NEGOTIATING POLITICIANS’ RESPONSIBILITIES IN NEWS INTERVIEWS     

Mats Ekström  Monika Djerf-Pierre  Bengt Johansson  Nicklas Håkansson 《Journalism Practice》2016,10(8):983-1004

News interviews are contexts in which political responsibilities are articulated and negotiated. Although the accountability interview is recognized as a commonsense practice in journalism, and the research on political interviews is substantial, it partly remains to explore how responsibilities are negotiated in different forms of questioning in journalism. This study investigates three generic forms of questioning: accountability questioning, the clarifying of promises, and the principal assessments. Key features of the different forms are specified. The empirical study investigates how the questionings are performed in news on industrial crises in Sweden, in the different political regimes in the 1970s and the 2000s. The data consist of 27 news interviews with the formally responsible Ministers. The method is based on Conversation Analysis and includes detailed analyses of questions and answers. The study shows (1) how the forms of questioning differ when it comes to the action agenda and in how responsibilities are invoked and negotiated; (2) how the questionings tend to reproduce particular expectations of Governmental interventions; (3) how increased assertiveness and adversarialness in interviewing coincide with reduced expectations of political responsibilities.  相似文献   

Validity of Holland’s theory in adolescence: evidence from a Slovak sample     

Martončik  Marcel  Kačmárová  Monika  Hruščová  Eva  Magáčová Žilková  Ivana  Kravcová  Michaela 《International Journal for Educational and Vocational Guidance》2020,20(3):543-565

The underlying calculus assumption of Holland’s theory was tested in two samples of primary school students (N₁ = 400 and N₂ = 250) with an average age of 13.86 and 14.14 years, respectively. Both exploratory and confirmatory multidimensional scaling and Hubert and Arabie’s randomization test of hypothesized order relations were calculated. The circular spatial arrangement of RIASEC types was not confirmed in either of the two samples. The study discusses possible causes of the inappropriateness of using Holland’s model in an adolescent sample.

Towards professionalisation? Restructuring of administrative work force in universities   总被引：1，自引：0，他引：1  

Åse Gornitzka  Ingvild Marheim Larsen 《Higher Education》2004,47(4):455-471

This article examines the restructuring ofadministrative staff in universities throughempirically documenting such processes andproviding a theoretically foundedinterpretation and analysis of change. Theempirical material is drawn from a context ofNorwegian universities the last two decades.Two major changes can be observed in thisperiod. First, a period of steep growth inuniversity administration in early 1990sfollowed by a period of moderate growth and insome cases even decline. The second dominantdevelopment pattern in the 1980s and 1990s isthe change within administrative staff,which could be interpreted as a professionalisation of administrative staff.The article concludes by presenting possibleexplanations to the structuring of theadministrative work force in universities onthe basis of different theoretical approachesto organisational change.  相似文献   

A Preliminary Examination of Identity Exploration and Commitment among Polish Adolescents with and without Motor Disability: Does Disability Constitute Diversity in Identity Development?     

Monika Dominiak-Kochanek 《International Journal of Disability, Development & Education》2016,63(3):357-368

The aim of this study was to define whether, and to what extent identity formation in late adolescence is disability specific. Ninety-eight adolescents participated in this study, including 43 students with motor disability and 55 students without disability. Identity exploration and commitment was measured by the Utrecht-Groningen Identity Development Scale which consists of subscales covering three identity domains: a school domain and a relational domain divided into two subdomains concerning relationships with peers and parents. The results showed that the amount of commitment and exploration was lesser in those with motor disability compared to those without disability; the most common identity status in participants with motor disability was diffusion, whereas those without disability were primarily achievers across the three domains. However, the findings revealed consistently non-significant interaction effects between disability/non-disability and commitment and exploration. Thus, what constitutes diversity in identity development is the amount of commitment and exploration made by adolescents with and without disability, suggesting a different pace, but not a different direction of identity change in both groups.  相似文献   

To give or not to give: children's and adolescents' sharing and moral negotiations in economic decision situations     

Gummerum M  Keller M  Takezawa M  Mata J 《Child development》2008,79(3):562-576

This study interconnects developmental psychology of fair and moral behavior with economic game theory. One hundred eighty-nine 9- to 17-year-old students shared a sum of money as individuals and groups with another anonymous group (dictator game). Individual allocations did not differ by age but did by gender and were predicted by participants' preferences for fair allocations. Group decision making followed a majority process. Level of moral reasoning did not predict individual offers, but group members with a higher moral reasoning ability were more influential during group negotiations and in influencing group outcomes. The youngest participants justified offers more frequently by referring to simple distribution principles. Older participants employed more complex reasons to justify deviations from allocation principles.  相似文献   

A Person-Centered Approach to Students' Evaluations of Perceived Fear Appeals and Their Association With Engagement     

Laura J. Nicholson  David W. Putwain  Ghada Nakhla  Benjamin Porter  Anthony Liversidge  Monika Reece 《Journal of Experimental Education》2019,87(1):139-160

A person-centered approach was employed to investigate how students' evaluation of perceived teacher utility value messages, i.e., fear appeals, as a threat and as a challenge, combined within individuals and how these combinations related to student engagement. Two studies were conducted with students in their final two years of secondary education. Empirically distinct clusters emerged at two time points in the academic year. Evaluating the message in the fear appeal at a higher level of challenge than threat was beneficial. Unexpectedly, high threat was associated with high engagement, as long as high challenge was also present, however, this combination was also related to high emotional disaffection. Moderate threat combined with moderate challenge had the most detrimental relationship with student engagement. Educational interventions should aim to increase the likelihood of a challenge evaluation.  相似文献   

Between the Academic Mathematics and the Mathematics Education Worlds     

CÅNDIDA QUEIROZ MOREIRA 《欧洲师范教育杂志》1997,20(2):171-189

Change is always difficult, and there is no great doubt that teachers need time to come to terms with it. This fact is, however, too often forgotten. In the spirit of my earlier work, this paper is shaped by an action research perspective. It provides some insights into the learning experiences of a group of eleven experienced secondary mathematics teacher, who were enrolled in a Perspectives on Mathematics Education two semesters course, within the context of a Masters on Mathematics Teaching programme, held at a Department of Mathematics, in a Portuguese University. The first part of the paper highlights the conflicting pressures and stresses suffered, during the first semester course, by the participating teachers. Confrontation with new ideas about both mathematics and mathematics education, as well as work overload, had a damaging impact on the teachers’ self‐confidence and morale. The second part of the paper covers the second semester course by addressing three fundamental questions for teachers, which aimed at helping the students bridge the academic mathematics and the mathematics education worlds. Finally, brief scenarios of three participating teachers’ professional development throughout the course are discussed in order to illustrate the challenges they had to face and the possibilities the course (and the Masters programme) offered to promote individual change.  相似文献   

Increased Implementation of Emergent Literacy Screening in Pre-Kindergarten     

Marcia Invernizzi  Timothy J. Landrum  Avery Teichman  Monika Townsend 《Early Childhood Education Journal》2010,37(6):437-446

The recent emphasis on universal prekindergarten programs, coupled with ongoing concern about children’s’ early literacy development in the first years of school, carry significant implications for how preschool educators program for literacy and assess literacy growth. We discuss the evolving role of literacy development in expanded preschool, examine key features of literacy assessments with particular attention to the content that might be assessed in preschool, and provide as an example one preschool literacy assessment tool that is in widespread use in the United States. We discuss the policy and practice implications of the growing emphasis on literacy assessment in preschoolers.  相似文献
