High school students’ difficulties in understanding osmosis   总被引:1,自引:0,他引:1  
Preconceptions and misconceptions of 500 secondary students in years 9‐12 regarding osmosis were studied through the use of five different kinds of instruments: prior learning inventory, self‐report knowledge inventory, true/false test, definitions and clinical interviews. Some of the major findings were: (1) The most frequent explanation offered to osmosis is ‘a desire or drive towards equalizing concentrations’. (2) Hardly any student uses the concept ‘water concentration’. (3) Most students fail to realize that in dynamic equilibrium water molecules keep moving. (4) Students have special difficulty in understanding osmotic relations in plants. (5) Many students have difficulty in grasping solute‐solvent and concentration‐quantity relations. (6) Students often perform laboratory experiments without really understanding the underlying principles. Practical and theoretical implications are discussed.  相似文献

This study focuses on the development of the understanding of historical time of pupils in primary school. We present a developmental model with three stages: emergent, initial and continued understanding of historical time. Based on this model, we constructed an instrument to measure how pupils aged 6–12 perform. The participants were 1457 pupils from 7 Dutch primary schools. The analysis of the data showed that in all three stages pupils in higher grades significantly outperformed pupils in lower grades and that pupils’ performances were influenced by the variables gender and parents’ education. In all grades, there seemed to be room for improvement, especially in the lower grades (ages 6–9) where pupils have hardly had any teaching on the understanding of historical time. However, in the higher grades as well (ages 10–12), pupils could improve on the level of continued understanding of historical time.  相似文献

Current reform efforts call for an emphasis on the use of representation in the mathematics classroom across levels and topics. The aim of the study was to examine teachers’ conceptions of representation as a process in doing mathematics, and their perspectives on the role of representations in the teaching and learning of mathematics at the middle-school level. Interviews with middle school mathematics teachers suggest that teachers use representations in varied ways in their own mathematical work and have developed working definitions of the term primarily as a product in problem solving. However, teachers’ conception of representation as a process and a mathematical practice appears to be less developed, and, as a result, representations may have a peripheral role in their instruction as well. Further, the data suggested that representation is viewed as a topic of study rather than as a general process, and as a goal for the learning of only a minority of the students—the high-performing ones. Implications for mathematics teacher education, prospective and practicing, are discussed.  相似文献

Some schools in the neighbourhood of Sefako Makgatho Health Sciences University (SMU) in South Africa persistently yielded poor mathematics results in the past years. This was of concern since maths is the main subject for many opportunities, including admissiontoSMUstudy programmes. Some SMU maths lecturers partnered with local schools to prepare the students in these schools. The aimwas to improve maths teaching and matric maths results. The teachers were assisted with maths concepts of most difficulty. This article describes the initiatives by some academics of SMU in achieving this.  相似文献

ABSTRACT

Background: While the school leader’s role is undoubtedly instrumental in school effectiveness, the specific influence of formal leadership on pupil learning is indirect and can be difficult to determine. Research findings suggest that school leaders can influence school organisation and pupil learning by acting catalytically, thus unlocking their schools’ existing potential. In school-based development, school leaders and their staff undergo a workplace development process, using school resources to contribute to it.

Purpose: This article explores the concept of leadership in school-based development, focusing on leading teacher learning processes in relation to pupil learning. The research problem is formulated in the following question: How is the school leader’s role enacted and experienced when enhancing teachers’ learning in school-based development? The intent of the study was to further the understanding of leadership in school-based development.

Sources of information and method: A qualitative interview study was conducted with teachers and leaders from three lower secondary schools, roughly 2 years after the schools participated in a formal school-based development project which was initiated by the Norwegian education authority. To present the findings based on the collected data, narrative texts were constructed.

Findings: The findings draw attention to the importance of leaders’ participation in the teacher learning processes of school-based development. The study highlights the importance of leaders building trust in their schools: development processes must be collegium-rooted with common goals for the whole school. The interplay of culture, structure and content is found to be necessary for successful school-based development. Furthermore, school leaders need to balance internal and external accountability, moving school practices towards local goals, which are constructed within national overall aims.

Conclusions: The study suggests that leaders require an overview of developmental processes to manage to support and progress development; leadership needs to be distributed. Further research on leaders’ learning in relation to school-based development can generate knowledge that serves as a thinking tool, thereby informing leaders’ actions in support of school-based development.  相似文献

Abstract

This paper highlights the importance of teaching all students in inclusive settings multiple literacies through their subject disciplines in the secondary school. After briefly discussing the responsibilities of the major stakeholders in the literacy process, the author provides examples of how strategies can be used to improve students’ literacy skills in the different subject disciplines.  相似文献

In a sample of 466 Chinese high school students, we examined the relationships between Chinese high school students’ stress in the school and their academic achievements. Regression mixture modelling identified two different classes of the effects of Chinese high school students’ stress on their academic achievements. One class contained 87% of the students. In this class, the students’ stress negatively predicted their academic achievements. For the other 13% of the students, their stress did not predict their academic achievements. Furthermore, we found that gender did not moderate the relationships between Chinese high school students’ stress in the school and their academic achievements.  相似文献

Principal’s hands-on strategies reflecting their theories of changing have a substantial effect on the development of their schools and on how the large-scale reform takes root. The study explores five comprehensive school principals’ leadership strategies during a large-scale school reform in Finland. The principals’ strategies in the middle of reform acknowledged the process nature of leading and involved coherence-making. The inclusive and learning-oriented strategies were applied quite consistently in terms of the horizontal, but not so much in the vertical coherence-making. Exclusive strategies we used to decrease teachers’ workload. Principals’ theories of changing seem to focus on creating and protecting teachers’ opportunities for meaningful learning.  相似文献

This paper is based on a preliminary exploration of the in‐depth interviews and focus groups that are part of a more extensive research project on the education of children of immigrants in Spain. In the process of migration, families undergo profound transformations that are often complicated by extended periods of separation—not only from extended family members, but also from the nuclear family. Though many immigrant families are involved in transnational separation and reunion processes of this kind, there has been little research on the impact of these forms of family transformations on the vision of education held by immigrants. This impact seems to be two‐fold. On one hand, family separation and living or work conditions hamper educational support and monitoring; on the other, the experience of migration poses a tremendous faith in the benefits of education and makes families highly motivated in education. The main idea underlying this paper is that an accurate knowledge of the schooling experience of the children of immigrants has to be related to the moral and psychological effects of this adaptive transformation and, in a very special way, to the weave of projects, expectations and frustrations that permeate the life of an immigrant family. The psychosocial consequences of the processes of adjustment and relearning that immigration entails, the need for a comparative perception of success and the willingness to make an effort and work hard make immigrant families strongly meritocratic and—contrary to some common beliefs—able to show a high level of commitment and expectations in relation to the education of their children.  相似文献

While there are several positive outcomes from implementing game design in a formal learning context, there are also challenges that have to be considered in order to improve game-based learning. This is explored in the article, using the concepts of activity frames and stancetaking, focusing on the social organization of the game design activity. Building on video data from one 6th grade class and one 7th grade class designing computer games based on their social studies curriculum, this article shows that tensions arise when students fail to agree on what the activity they are doing is really about: The academic content and what students commonly perceive as school activities, or a game design activity informed by their leisure time. The main argument is that the students position themselves as students, game designers or characters, and that this may cause tensions in the students’ social interactions.  相似文献

Teachers’ innovative behaviour influences not only their teaching practices and professional habits, but also has an impact on students’ creation of novel and original ideas. In spite of the increasing demand for innovative behaviour, and also relatively high academic achievements of Estonian students in international comparison, teachers in Estonia often do not use innovative teaching practices, according to Teaching and Learning International Survey (TALIS). This study explores possible school environmental factors that may support the innovative behaviour of teachers. A model, where self-efficacy as a trait and different types of teaching practices as behaviour, are components of the model of teachers’ innovative behaviour. It is supposed that teachers’ innovative behaviour appears in school environments and may be supported by the following factors: interaction and involvement, need and freedom for innovation. The study is carried out as a secondary data analysis, based on a sample of TALIS survey. The results indicate that although the three factors mentioned do not constitute the integrated phenomenon, they do describe different aspects of a teachers’ innovative behaviour.  相似文献

In the present online survey, 158 teachers in regular and special education teaching in grades six to nine were asked to rate the importance of probable reasons for problematic school absenteeism. On average, the teachers estimated that among their students, 19 students had presented with problematic school absenteeism over the last five years. Teachers viewed school absenteeism as a multifactorial problem. Family factors were considered to contribute most and low mood or depression were rated as one of the five most contributing factors. Teachers in special education viewed school factors as more influential than teachers in mainstream education did (t156 = ?3.94, p < 0.05). The current findings stress the importance of collaboration between the school, parents and the student to be able to address all factors that may lead to problematic school absenteeism.  相似文献

School connectedness has been shown to be an important protective factor in adolescent development, which is associated with reduced risk-taking behavior. Interventions to increase students’ connectedness to school commonly incorporate aspects of teacher training. To date, however, research on connectedness has largely been based on student survey data, with no reported research addressing teachers’ perceptions of students’ connectedness and its association with student behavior. This research attempted to address this gap in the literature through in-depth interviews with 14 school teachers and staff from two Australian high schools. Findings showed that teachers perceived students’ connectedness to be important in regard to reducing problem behavior, and discussed aspects of connectedness, including fairness and discipline, feeling valued, belonging and having teacher support, and being successfully engaged in school, as being particularly important. This research enables the development of school-based intervention programs that are based on both student- and teacher-focused research.  相似文献

In previous research, few studies have examined the effects of adolescents’ stress in school on the change rates of their academic achievement. In the present study, we seek to examine the longitudinal relationships between adolescents’ stress in school and the change rates of their academic achievement. The results indicated that for those whose academic achievement significantly declined over time, the students’ stress from teacher–student interaction significantly predicted the change rates of their academic achievement. The findings provided support to the notion that stress was a risk factor in students’ academic development.  相似文献

Abstract

Despite a wide international literature on the effect of vocational and general education on school-to-work transition, relatively little is known about the role of having studied specific subjects in explaining inequalities in young people’s labour market outcomes. This paper aims to fill this gap by examining differences in employment chances of young people who left education early, either at the end of compulsory schooling or at the end of secondary school. Using data from the Scottish Longitudinal Study, a large-scale linkage study created using data from administrative and statistical sources, we found little gender differences but strong parental background differences in school leavers’ employment status and type of occupation entered. Social inequalities in labour market outcomes were only partly explained by curriculum choices. Moreover, after controlling for social origin and grades, only history and business for lower-secondary leavers and maths for upper-secondary leavers were associated with a reduction in the chances of being unemployed/inactive.  相似文献

This article explores how comprehensive school teachers’ sense of professional agency changes in the context of large-scale national educational change in Finland. We analysed the premises on which teachers (n = 100) view themselves and their work in terms of developing their own school, catalysed by the large-scale national change. The study included theory-driven interventions in the case school communities, as well as pre- and post-test measurements. The results suggested that the learning of active professional agency was facilitated among teachers during the 2 years of development work. A significant number of teachers had adopted a more holistic orientation towards the reform. Moreover, the number of teachers who considered themselves as the subjects of the development work increased slightly. This increase suggests that teachers’ intentional and responsible management of new learning proceeds from the interpersonal meaning-making process to the internal process that regulates the elements of a teacher’s professional agency.  相似文献

Groups of mathematically strong and weak second-, fourth- and sixth-graders were individually confronted with numerosities smaller and larger than 100 embedded in one-, two- or three-dimensional realistic contexts. While one third of these contexts were totally unstructured (e.g., an irregular piece of land jumbled up with 72 cars), another third had a clear structure (e.g., a 16x4 rectangular parking lot completely filled with 64 cars), and a last third had a “semi-structure” (e.g., the same 16x4 parking lot but with a number of cars missing). Besides analyzing the effects of different task and subject variables on pupils’ accuracy and response-time data, the study involved and analysis of their estimation strategies, with an emphasis on multiplicative strategies that profited by some of the tasks’ geometrical (semi-)structure. It was found that many children actually made use of such strategies, that using these strategies did however not always led to accurate estimations, and that their frequency and efficiency increased with age.  相似文献

This paper explores teachers’ and school leaders’ perceptions of commercialisation in Australian public schools, reporting on findings from an open-ended survey question from an exploratory study that sought to investigate teacher and school leader perceptions and experiences of commercialisation. Commercialisation, for the purposes of this paper, is understood as the creation, marketing and sale of education goods and services to schools by for-profit providers and often includes (but is not limited to) the provision of curriculum content, assessment services, data infrastructures, digital learning, remedial instruction, professional development and school administration support. Our account highlights that commercialisation is prevalent in the day-to-day practice of Australian public schools. The perceptions of teachers and leaders suggest that commercialisation is complex, with both affordances and challenges. Respondents acknowledged that aspects of commercialisation are necessary for successfully running schools and classrooms in the 21st century, but also noted that there is a fine line beyond which these seemingly innocuous services become perilous. Concerns focused on how particular services are leading to the deprofessionalisation of teachers as they have less autonomy over what to teach and how to teach it. Moreover, teachers and school leaders reported being perturbed by the idea that commercial providers and services might work to replace teachers in the future. Drawing on these data we argue that growing commercialisation in Australian public schools clearly requires an ethical debate that schools, education professionals, policy makers and interested publics are yet to have.  相似文献

Widely thought to be something worth encouraging in young learners, creativity has popularly been associated more with music and art than with other areas of the curriculum. There have been many studies of creativity but few that focus explicitly on what counts as creative thinking in specific subject areas. The aim of the research reported here was to determine pre-service teachers’ conceptions of creativity within the curriculum for English. The study involved analyses of primary school trainee teachers’ responses to questionnaires and follow-up focus group discussion to identify their conceptions. A group of 48 trainees in the final year of an undergraduate degree in primary education leading to qualified teacher status in England completed the questionnaire. Of these, eight volunteered to participate in a follow-up focus group discussion to further explore ideas. Responses were analysed quantitatively and qualitatively. Conceptions of creativity in English were found to be limited, focused mainly on naïve views of story writing and dramatic activity. Responses indicated that they were often unable to distinguish clearly between the concept of creativity, an example of its occurrence in the classroom, and what feature of that example made it creative. Consequently, their limited constructions of creativity were confused. It is important that teachers in schools as well as those responsible for training teachers in universities are advised that trainees’ conceptions of creativity in English may be inadequate in several respects and that they may not recognise opportunities for creativity. Pre-service training programmes could well benefit from structured courses on the forms and applications of creativity.  相似文献

The aim of the present study was to examine the relations of students’ intrinsic motivation in physical education lessons with factors such as perceived locus of causality, perceived competence and outcome expectancies. Five hundred sixteen students of grades 7–12 participated in the study. The students were randomly selected from three schools located in a medium sized town in Greece. Perceived locus of causality was examined using Ryan and Connell’s (1989) motivational orientation scales, while intrinsic motivation was assessed by means of the Intrinsic Motivation Inventory (Ryan, 1982). Outcome expectancies for ten possible outcomes of school physical education were assessed by means of two different scales, namely outcome evaluation and outcome likelihood. Causal modelling analysis showed that intrinsic motivation was mainly influenced by perceived usefulness which in turned was influenced by outcome expectations. Moreover, outcome expectations also influenced perceived locus of causality. These results show that students’ outcome expectancies for their participation in school physical education is an important factor influencing their intrinsic motivation.  相似文献
