This study investigated whether mathematics education based on a multi-tiered response to intervention (RTI) model can support students' arithmetic competence in primary schools in Sweden. The intent was to identify and support students at risk of failure. In this study, 113 students participated in the intervention, and 30 students participated in the control group. Both groups were followed from Grade 1 to the end of Grade 2 and compared. During the first semester in Grade 1, all students were taught basic addition and subtraction with explicit instructions in Tier 1. Those who did not respond to Tier 1 after one semester were provided support within Tier 2 during the second semester. The same was repeated in grade 2 and the students that did not respond to Tier 2 were supported within Tier 3. At the end of Grade 2, students in the intervention group performed significantly higher on the basic arithmetic competence in the number range 1–9 than the control group. No significant difference was found in a test measuring basic arithmetic competence in the number range 10–19. This study shows that using multi-tiered RTI might be sufficient to identify and support students at risk in early arithmetic competence.  相似文献

With the increasing popularity of peer assessment as an assessment tool, questions may arise about its measurement quality. Among such questions, the extent peer assessment practices adhere to standards of measurement. It has been claimed that new forms of assessment, require new criteria to judge their validity and reliability, since they aim for specific goals and address different aspects of learning. But although new criteria have been formulated, little is known about how they are deployed and operate in actual peer assessment practices. This study intends to explicate the quality criteria relevant to the context of peer assessment. We conducted a survey in vocational education on peer assessment quality criteria applied in classrooms. Fifty-six teachers using peer assessment rated several quality criteria as relevant to their teaching practice. The findings suggest that peer assessment practices entail many of the quality criteria recognized in measurement and evaluation, although in an embedded way: the generic quality criteria are tuned or adapted to the peer assessment setting. The findings also show that peer assessment is very much in the hands of the teacher, who organizes and orchestrates the appraisal process in which students receive clear guidelines to appraise one another's work. Our results indicate that quality criteria hardly differ from the function peer assessment serves in classrooms, either within a summative or formative evaluation context. By gaining insight on the specific criteria of peer assessment and their precise purposes, we believe it becomes possible to help teachers improve its measurement quality.  相似文献

This article discusses rural schoolteachers’ relationships with local village communities in mid-twentieth-century Finland. At the time, Finnish rural teachers were typically very public figures in their local community. To deal with the pressures of their position, teachers resorted to coping strategies which the authors name ‘local’ and ‘cosmopolitan’ after Robert K. Merton’s well-known categories. The local strategy required that teachers adapt themselves to the social demands of community life, whereas the cosmopolitan strategy was manifested in the teachers’ efforts to distance themselves from the local community, reflecting the increasing professionalisation of Finnish schoolteachers as well as a general social transition in which traditional community ties were gradually replaced by modern individualism.  相似文献

A number of measures have been taken by the society to ensure gender equality in higher education. Nevertheless, women still face great difficulties when pursuing an academic career. Our aim is to increase the understanding of how the society, conceptualised as the organisational field, interacts with organisational factors and personal actions as women try to establish themselves within academia. We followed a group of female PhD students and their struggle to graduate at a Swedish, traditionally male‐dominated, university department. The paper analyses how actors and regulations in the society interact with the department’s gendered structures and practices. Three processes that influenced the women’s career opportunities have been identified – a process of integration, liberation and legitimatisation. We also show that women can get accepted and realise their short‐term objective, based on support from the society, while not necessarily being included by the department in a longer‐term perspective.  相似文献

The article presents some findings from the York‐Jyväskylä Teacher Professionalism project. The project was a follow‐up study to earlier case‐study research in six schools in Finland and six schools in England on the impact of educational reforms on teachers' work. Data were collected by re‐interviewing a sample of teachers from the original schools six years later. The views of English and Finnish teachers concerning the ways in which changes in practice, pay and working conditions affected their perception of teaching as a profession are contrasted. The crucial factors discouraging teachers from remaining in teaching were work intensification, low pay, deteriorating pupil behaviour and a decline in public respect. Positive influences on teacher retention were commitment to children, professional freedom and supportive colleagues. Suggestions are offered as to how policy makers should act to preserve the commitment of primary teachers and to promote their retention.  相似文献

Evaluating the performance of a biotrickling filter for the treatment of wastewaters produced by a company manufacturing beer was the aim of this study. A pilot scale trickling filter filled with gravel was used as the experimental biofilter. Pilot scale plant experiments were made to evaluate the performance of the trickling filter aerobic and anaerobic biofilm systems for removal of chemical oxygen demand (COD) and nutrients from synthetic brewery wastewater. Performance evaluation data of the trickling filter were generated under different experimental conditions. The trickling filter had an average efficiency of (86.81±6.95)% as the hydraulic loading rate increased from 4.0 to 6.4 m3/(m2·d). Various COD concentrations were used to adjust organic loading rates from 1.5 to 4.5 kg COD/(m3·d). An average COD removal efficiency of (85.10±6.40)% was achieved in all wastewater concentrations at a hydraulic loading of 6.4 m3/(m2·d). The results lead to a design organic load of 1.5 kg COD/(m3·d) to reach an effluent COD in the range of 50–120 mg/L. As can be concluded from the results of this study, organic substances in brewery wastewater can be handled in a cost-effective and environmentally friendly manner using the gravel-filled trickling filter.  相似文献

Objective. This article focuses on identity as a parent in relation to parenting and psychological functioning in middle age. Design. Drawn from the Jyväskylä Longitudinal Study of Personality and Social Development, 162 participants (53% females) with children (age 36), represented the Finnish age-cohort born in 1959. Parental identity was assessed at ages 36, 42, and 50. Results. In both women and men, parental identity achievement increased from age 36 to 42 and remained stable to 50. The level of parental identity achievement was higher in women than in men. Achievement was typical for women and foreclosure for men. Participants’ education, occupational status, and number of offspring were not related to parental identity status. As expected, parental identity achievement was associated with authoritative (indicated by higher nurturance and parental knowledge about the child’s activities) parenting style. No significant associations emerged between parental identity foreclosure and restrictiveness as an indicator of authoritarian parenting style. The diffused men outscored others in parental stress. Achieved parental identity was related to generativity in both genders and to higher psychological and social well-being in men. Conclusions. At present, many parenting programs are targeted to young parents. This study highlighted the importance of a later parenting phase at around age 40, when for many, the children are approaching puberty. Therefore, parenting programs and support should also be designed for middle-aged parents. Specifically men may need additional support for their active consideration and engagement in the fathering role.  相似文献

ABSTRACT

What are the current challenges and opportunities for bringing actor-network theory (ANT) into issues-based science education? This article discusses experiences gained from introducing an educational version of ANT deploying digital technology into an upper secondary school science class. This teaching innovation, called controversy mapping, has been pioneered in different contexts of higher education before being adapted to school education. Experimenting with controversy mapping in a Swedish science class raised both conceptual and practical issues. These centre on: (1) how ANT-inspired controversy mapping redesigns the citizenship training enacted by institutionalized approaches to issues-based education as socioscientific issues (SSI); (2) how controversy mapping reconfigures the interdisciplinarity of issues-based science education; and (3) how controversy mapping displaces scientific literacy and knowledge of the nature of science as guiding concerns for teaching in favour of new preoccupations with digital literacy and digital tools and methods as contemporary infrastructures of free and open inquiry.  相似文献
