The purpose of this study was to construct and study the impact of a research‐based sequence for teaching the concept of modelling to seventh‐grade science students. We identified students' notions of models and the aspects of school science to be addressed regarding the model concept, which were then taken into account when we planned the learning sequence. The idea of modelling in science was taught while the students were learning about the change of states of matter in seventh‐grade physics. A pre‐interview revealed that the students' notions of models were very limited, while a post‐interview showed that this improved in the course of the series of lessons. There was also a statistically significant difference in the students' understanding of modelling between our target group and a control group consisting of ninth‐grade students who had received only the normal teaching. However, a delayed post‐questionnaire completed a few months after the teaching sequence showed that the stability of learning results were dependent on whether models and modelling were used in the normal teaching conducted after the teaching sequence. Implications for teaching, teacher education and research are also addressed in this paper.  相似文献

This article examines the impact of an adjunct English language tutorial program on the academic performance of first‐year Architecture students. With increasing numbers of international students enrolling in Australian universities, language and academic skills programs have shifted from generic to more discipline‐specific models; however, there has been little research on the effects of these programs on ESL students' academic performance. This study uses a mixed‐method approach to evaluate the effectiveness of an English as a second language (ESL) intervention program. Findings indicate that students value a highly discipline‐specific approach to language and academic skills support and that regular participation in a content‐based ESL program can lead to positive learning outcomes for students. Preliminary findings also suggest that there are positive longer‐term benefits on students' academic outcomes. The authors suggest the need for longitudinal studies on the impact of discipline‐based programs for ESL students.  相似文献

The aim of this study was to identify how and why doctoral students do interdisciplinary research. A mixed-methods approach utilising bibliometric analysis of the publications of 195 students identified those who had published interdisciplinary research. This objective measurement of the interdisciplinarity, applying the Rao-Stirling index to Web of Science and Scopus citations, allowed for a comparison of students’ interdisciplinary research outcomes from three different computer science programmes: a traditional programme, a multidisciplinary doctoral school and an interdisciplinary doctoral college. Applying a sociocultural approach, interviews with the 15 most interdisciplinary students were analysed to understand how dispositions and experiences of students and factors of the different programmes affect the circumstances and processes of becoming an interdisciplinary early career scientist. The data indicate that student motivations, previous skills and knowledge interacted with policies and programme structures including type of funding and supervisor expectations to play a crucial role in interdisciplinarity at the doctoral level. These factors can give rise to interdisciplinary research even in programmes without interdisciplinary focus and compromise the interdisciplinary goals of interdisciplinary programmes.  相似文献

I respond to Pike and Dunne by exploring the utilization of citizen science in science education. Their results indicate that students fail to pursue science beyond the secondary level, in part, because of prior educational experiences with science education. Students lack motivation to pursue degrees and careers in science because they feel science is not relevant to their lives or they are simply not good at science. With this understanding, the science education community now needs to move beyond a discussion of the problem and move forward with continued discourse on possible solutions. Science educators need to focus on developing connections between students’ everyday lives and science so that they will have tangible reasons for continuing with the lifelong learning of science. In this response, I will show that citizen science as an educational context holds much promise, respectively. Participation in citizen science projects moves scientific content from the abstract to the tangible involving students in hands-on, active learning. In addition, if civic projects are centered within their own communities, then the science becomes relevant to their lives because it is focused on topics in their own backyards.  相似文献

ABSTRACT

Higher-education students now have more alternatives for searching for information than previous generations had. The Internet is a vast ocean of information sources, albeit with diverse reliability and quality. In Web 2.0 platforms, any participant can be a content creator. This reality is challenging for both the instructors and the students. We conducted interviews with 12 Computer Science students and 8 instructors from two universities to (a) identify the difficulties students encounter, if at all, (b) identify the learning processes that students undergo, if at all, when using the Internet for their CS studies, in particular, programming tasks; and (c) elicit instructors’ perceptions of students’ use of the Internet. Both students and instructors agreed that although using the Internet is not trivial, direct teaching of this skill is unnecessary. Instructors differed in their attitudes towards students’ use of the internet. We found that in the first year the students’ use of the Internet and their difficulties are similar to reports in the empirical literature, and echo the instructors’ concerns. However, after extensive experience, students undergo a learning process, and their ability to navigate the myriad sources, as well as to search, manage, and effectively evaluate Internet sources improves. Students mentioned their improved abilities to code as a means to effectively evaluate information sources.  相似文献

In the past 20 years, the landscape of Higher Education in the United Kingdom has changed considerably. With the prospect of tuition fees spiralling above £9,000 per year, per student, it is important to explore the impact this has upon the student experience. In spite of the vast financial investment current students make towards their education, student attendance and engagement remain low. The present study therefore adopted a qualitative approach using focus groups to explore reasons for non-attendance at university teaching sessions. Four key themes emerged; these surrounded issues about a sense of belonging to university, views of the teaching (material taught and the personality and method of the tutor), perceptions of being a consumer and external pressures. This research suggests that universities should pay particular attention to the reasons why students do not attend and possibly change practice, providing more support where appropriate.  相似文献

In the past decade there has been a dramatic growth in UK student numbers. Widening participation policies are encouraging students from non‐traditional backgrounds to enter higher education. Southampton Institute has found that many non‐traditional students have had little preparation for academic life. These students often have unrealistic expectations of higher education, expectations that sometimes are at odds with a successful transition from secondary to higher education. In addition higher education institutions are often unaware of the way that higher education is perceived by non‐traditional students. This situation cannot remain unchecked and requires some form of discourse. In this paper, a framework used to model a reflective discourse between stakeholders (student, institution) is introduced, and a case study demonstrating the behaviour of an automated negotiation mechanism is presented.  相似文献

Abstract

This is a multiple‐indicators evaluation of an innovative approach, using self‐paced learning modules accompanying computerised exercises as an adjunct to teaching quantitative concepts and skills to environmental science students at university. The evaluation data, based on a pre‐unit and a post‐unit questionnaire survey completed by 38 students, show high levels of student satisfaction with the unit as a whole, and the self‐paced workbooks in particular. Students also indicated a clear preference for learning from self‐paced workbooks compared to learning from textbooks. Some students applied the quantitative skills acquired to other academic units, or took the initiative to learn to use additional statistical procedures (not covered in the unit) for academic purposes. However, comparison of students’ levels of interest and confidence in quantitative subjects before and after the completion of the unit did not yield significant changes. Implications of the research findings for university science education are discussed.  相似文献

This paper explicates a pattern of scientific argumentation in which scientists respond to causal questions with the generation and test of alternative hypotheses through cycles of hypothetico‐predictive argumentation. Hypothetico‐predictive arguments are employed to test causal claims that exist on at least two levels (designated stage 4 in which the causal claims are perceptible, and stage 5 in which the causal claims are imperceptible). Origins of the ability to construct and comprehend hypothetico‐predictive arguments at the highest level can be traced to pre‐verbal reasoning of the sensory‐motor child and the gradual internalization of verbally mediated arguments involving nominal, categorical, causal and, finally, theoretical propositions. Presumably, the ability to construct and comprehend hypothetico‐predictive arguments (an aspect of procedural knowledge) is necessary for the construction of conceptual knowledge (an aspect of declarative knowledge) because such arguments are used during concept construction and conceptual change. Science instruction that focuses on the generation and debate of hypothetico‐predictive arguments should improve students' conceptual understanding and their argumentative/reasoning skills.  相似文献

This article is a response to Pike and Dunne’s research. The focus of their analysis is on reflections of studying science post-16. Pike and Dunne draw attention to under enrollments in science, technology, engineering, and mathematics (STEM) fields, in particular, in the field of physics, chemistry and biology in the United Kingdom. We provide an analysis of how the authors conceptualize the problem of scientific career choices, the theoretical framework through which they study the problem, and the methodology they use to collect and analyze data. In addition, we examine the perspective they provide in light of new developments in the field of students’ attitudes towards science and mathematics. More precisely, we draw attention to and explicate the authors’ use of identity from the perspective of emerging theories that explore the relationships between the learner and culture in the context of science and mathematics.  相似文献

As concerns about participation rates in post-compulsory science continue unabated, considerable research efforts have been focused on understanding and addressing the issue, bringing various theoretical lenses to bear on the problem. One such conceptual lens is that of ‘science capital’ (science-related forms of social and cultural capital), which has begun to be explored as a tool for examining differential patterns of aspiration and participation in science. This paper continues this line of work, attempting to further refine our conceptualisation of science capital and to consider potential insights it might offer beyond existing, related constructs. We utilise data from two surveys conducted in England as part of the wider Enterprising Science project, a broader national survey and a more targeted survey, completed by students from schools generally serving more disadvantaged populations. Logistic regression analyses indicated that science capital was more closely related than cultural capital to science aspirations-related outcome variables. In addition, further analyses reflected that particular dimensions of science capital (science literacy, perceived transferability and utility of science, family influences) seem to be more closely related to anticipated future participation and identity in science than others. These patterns held for both data sets. While these findings are generally in alignment with previous research, we suggest that they highlight the potential value of science capital as a distinct conceptual lens, which also carries particular implications for the types of interventions that may prove valuable in considering ways to address disparities in science engagement and participation.  相似文献

The effects of levels of aggregation on measures of goodness of fit and higher order parameter estimates obtained from confirmatory factor analysis (CFA) were investigated. For a higher order model of academic self‐concept, 3 levels of aggregation were considered—disaggregated, partially disaggregated, and partially aggregated. In the disaggregated model, measured variables represented individual items. In the partially disaggregated model, testlets (groups of 4 items) represented measured variables. In the partially aggregated model, subscale scores represented measured variables. Three indexes of fit were employed: the Tucker‐Lewis Index (TLI), the Comparative Fit Index (CFI), and chi‐square. Solutions for the disaggregated models consistently evidenced poor fit. TLI and CFI values for partially disaggregated and partially aggregated solutions were satisfactory. Standardized parameter estimates were similar across all solutions. Implications of these findings are discussed with consideration of other research on model complexity in CFA.  相似文献

ABSTRACT

This cross-sectional study explored students’ conceptions of science learning via drawing analysis. A total of 906 Taiwanese students in 4th, 6th, 8th, 10th, and 12th grade were asked to use drawing to illustrate how they conceptualise science learning. Students’ drawings were analysed using a coding checklist to determine the presence or absence of specified attributes. Data analysis showed that the majority of students pictured science learning as school-based, involving certain types of experiment or teacher lecturing. In addition, notable cross-sectional differences were found in the ‘Activity’ and ‘Emotions and attitudes’ categories in students’ drawings. Three major findings were made: (1) lower grade level students conceptualised science learning with a didactic approach, while higher graders might possess a quantitative view of science learning (i.e. how much is learned, not how well it is learned), (2) students’ positive and negative emotions and attitudes toward science learning reversed around middle school, and (3) female students expressed significantly more positive emotions and attitudes than their male counterparts. In conclusion, higher graders’ unfruitful conceptions of science learning warrant educators’ attention. Moreover, further investigation of girls’ more positive emotions and attitudes found in this study is needed.  相似文献

Abstract

An increasing number of researchers are investigating the effect of students’ prior knowledge and beliefs on their development of scientific concepts. Much of this research is taking place within the framework of constructivism, and is attracting the attention of science educators in non‐western countries. This integrative research review has been undertaken to help researchers and practitioners to identify issues for further investigation and reflection. The results suggest that ‘cosmetic’ attempts to nationalize western science curricula in non‐western countries are likely to prove ineffective because the problem, from the students’ perspective, is one of poor ‘fit’ between their world‐views, language meanings and prior beliefs and those inherent in the subject. A constructivist paradigm seems to offer good prospects for both understanding the problem and formulating learning strategies in science education which are better suited to non‐western cultures. Nevertheless, constructivist pedagogies imported from the West should be examined for their cultural appropriateness.  相似文献

Primary science education is a concern around the world and quality mentoring within schools can develop pre‐service teachers' practices. A five‐factor model for mentoring has been identified, namely, personal attributes, system requirements, pedagogical knowledge, modelling, and feedback. Final‐year pre‐service teachers (mentees, n = 211) from three Turkish universities were administered a previously validated instrument to gather perceptions of their mentoring in primary science teaching. ANOVA indicated that each of these five factors was statistically significant (p<.001) with mean scale scores ranging from 3.36 to 4.12. Although mentees perceived their mentors to provide evaluation feedback (95%), model classroom management (88%), guide their preparation (96%), and outline the science curriculum (92%), the majority of mentors were perceived not to assist their mentees in 10 of the 34 survey items. Professional development programmes that target the specific needs of these mentors may further enhance mentoring practices for advancing primary science teaching.  相似文献
