Background: Past studies have shown significant associations between students’ conceptions of learning science and their science learning self-efficacy. However, in most of the studies, students’ science learning self-efficacy has often been measured by a singular scale.

Purpose: Extending the findings of these studies, the present study adopted a multi-dimensional instrument to assess Taiwanese high school students’ science learning self-efficacy and investigate the relationships with their conceptions of learning science.

Sample: A total of 488 Taiwanese high school students (265 male and 223 female) were invited to participate in this survey.

Design and method: All the participants responded to the Conceptions of Learning Science (COLS) questionnaire regarding ‘Memorizing’, ‘Testing’, ‘Calculating and practicing’, ‘Increase of knowledge’, ‘Applying’ and ‘Understanding and seeing in a new way’ and the Science Learning Self-Efficacy (SLSE) instrument, including ‘Conceptual understanding’, ‘Higher-Order cognitive skills’, ‘Practical work’, ‘Everyday application’ and ‘Science communication’.

Results: The path analysis results derived from the structural equation modeling method indicated that, of all five SLSE dimensions, the ‘Understanding and seeing in a new way’ COLS displayed as a positive predictor, while the ‘Testing’ COLS was a significant negative predictor. The ‘Applying’ COLS item can only positively contribute to the SLSE dimensions of ‘Higher-Order thinking skills’, ‘Everyday application’ and ‘Science Communication’.

Conclusions: In general, students in strong agreement with learning science as understanding and seeing in a new way or the application of learned scientific knowledge are prone to possess higher confidence in learning science. However, students who consider learning science in terms of preparing for tests and examinations tend to hold lower science learning self-efficacy.  相似文献

Background: Inquiry-based science education (IBSE) is suitable to teach scientific contents as well as to foster scientific skills. Similar conclusions are drawn by studies with respect to scientific literacy, motivational aspects, vocabulary knowledge, conceptual understandings, critical thinking, and attitudes toward science. Nevertheless, IBSE is rarely adopted in schools. Often barriers for teachers account for this lack, with the result that even good teachers struggle to teach science as inquiry. More importantly, studies indicate that several barriers and constraints could be ascribed to problems teacher students have at the university stage.

Purpose: The purpose of this explorative investigation is to examine the problems teacher students have when teaching science through inquiry. In order to draw a holistic picture of these problems, we identified problems from three different points of view leading to the research question: What problems regarding IBSE do teacher students have from an objective, a subjective, and a self-reflective perspective?

Design &; method: Using video analysis and observation tools as well as qualitative content analysis and open questionnaires we identified problems from each perspective.

Results: The objectively stated problems comprise the lack of essential features of IBSE especially concerning ‘Supporting pupils’ own investigations’ and ‘Guiding analysis and conclusions.’ The subjectively perceived problems comprise concerns about ‘Teachers’ abilities’ and ‘Pupils’ abilities,’ ‘Differentiated instruction’ and institutional frame ‘Conditions’ while the self-reflectively noticed problems mainly comprise concerns about ‘Allowing inquiry,’ ‘Instructional Aspects,’ and ‘Pupils’ behavior.’

Conclusions: Each of the three different perspectives provides plenty of problems, partially overlapping, partially complementing one another, and partially revealing completely new problems. Consequently, teacher educators have to consider these three perspectives.  相似文献

Background: In Bangladesh, a common science curriculum caters for all students at the junior secondary level. Since this curriculum is for all students, its aims are both to build a strong foundation in science while still providing students with the opportunities to use science in everyday life – an aim consistent with the notion of scientific literacy.

Purpose: This paper reports Bangladeshi science teachers’ perspectives and practices in regard to the promotion of scientific literacy.

Sample: Six science teachers representing a range of geographical locations, school types with different class sizes, lengths of teaching experience and educational qualifications.

Design and method: This study employed a case study approach. The six teachers and their associated science classes (including students) were considered as six cases. Data were gathered through observing the teachers’ science lessons, interviewing them twice – once before and once after the lesson observation, and interviewing their students in focus groups.

Results: This study reveals that participating teachers held a range of perspectives on scientific literacy, including some naïve perspectives. In addition, their perspectives were often not seen to be realised in the classroom as for teachers the emphasis of learning science was more traditional in nature. Many of their teaching practices promoted a culture of academic science that resulted in students’ difficulty in finding connections between the science they study in school and their everyday lives. This research also identified the tension which teachers encountered between their religious values and science values while they were teaching science in a culture with a religious tradition.

Conclusions: The professional development practice for science teachers in Bangladesh with its emphasis on developing science content knowledge may limit the scope for promoting the concepts of scientific literacy. Opportunities for developing pedagogic knowledge is also limited and consequently impacts on teachers’ ability to develop the concepts of scientific literacy and learn how to teach for its promotion.  相似文献

ABSTRACT

Background: Teachers have the potential to make an enormous positive impact on the lives of their students, and may enter the classroom with a deep-set belief that education is, fundamentally, benevolent and good. However, such an uncritical stance may fail to account for the negative experiences of Indigenous students in Australia, where teachers are often cited as the primary reason Indigenous students leave school or refuse to go to school. Despite this, Aboriginal communities remain strong advocates of education and continue to lobby for a genuine and meaningful role in decision making.

Purpose: Given teachers’ critical influence, a collaboration was formed between the two authors: a Gamilaroi (Aboriginal) woman and a non-Indigenous Canadian woman, to conduct a review of the research. We asked: ‘What are the personal (non-academic) attributes a teacher needs to engage Indigenous students effectively in the learning process?’

Method: The literature review focused primarily on the Australian context and used a framework-based synthesis approach, whereby a decolonising ‘Relationally Responsive Standpoint’ framework was identified a priori. This provided the structure for extracting and synthesising the literature.

Findings and Discussion: The themes arising from the literature review were organised and considered through the framework, which foregrounds awareness through Respecting (self/motivations), Connecting (interpersonal) and Reflecting (knowledge) before concluding by Directing (future role). In Directing, the implications of the findings are discussed through yarning, a dialogical and dynamic approach with a strong future focus regarding the next steps of research and action.

Conclusions: Reviewing the literature in this way offers teachers, researchers, teacher educators and, arguably, policy-makers an opportunity to consider the personal attributes necessary to engage Indigenous students. It highlights the importance of critical self-reflection to being a relationally responsive teacher. We believe that the findings span international and professional boundaries and could impact on Indigenous Peoples globally, if all professions engage with an understanding of their own axiology and ontology.  相似文献

Background: Research has primarily concentrated on adults’ implicit theories about high quality science education for all students. Little work has considered the students’ perspective. This study investigated high school students’ implicit theories about what helped them learn science.

Purpose: This study addressed (1) What characterizes high school students’ implicit theories of what facilitates their learning of science?; (2) With respect to students’ self-classifications as African American or European American and female or male, do differences exist in the students’ implicit theories?

Sample, design and methods: Students in an urban high school located in south-eastern United States were surveyed in 2006 about their thoughts on what helps them learn science. To confirm or disconfirm any differences, data from two different samples were analyzed. Responses of 112 African American and 118 European American students and responses from 297 European American students comprised the data for sample one and two, respectively.

Results: Seven categories emerged from the deductive and inductive analyses of data: personal responsibility, learning arrangements, interest and knowledge, communication, student mastery, environmental responsiveness, and instructional strategies. Instructional strategies captured 82% and 80% of the data from sample one and two, respectively; consequently, this category was further subjected to Mann-Whitney statistical analysis at p < .05 to ascertain ethnic differences. Significant differences did not exist for ethnicity but differences between females and males in sample one and sample two emerged.

Conclusions: African American and European American students’ implicit theories about instructional strategies that facilitated their science learning did not significantly differ but female and male students’ implicit theories about instructional strategies that helped them learn science significantly differed. Because students attend and respond to what they think and perceive to be important, addressing students’ implicit theories may be one way to enhance science education reform.  相似文献

This study investigated Indonesian and Japanese senior high-school students’ understanding of electrochemistry concepts.

Sample

The questionnaire was administered to 244 Indonesian and 189 Japanese public senior high-school students.

Design and methods

An 18-item multiple-choice questionnaire relating to five conceptual categories (reactions occurring during electrolysis, differences between electrolytic and voltaic cells, movement of ions in voltaic cells, poles in voltaic cells, voltaic cell reactions) was administered.

Results

The findings of this study show that difficulties and alternative conceptions previously reported in the literature are held equally by students from a developing and developed country, Indonesian and Japan respectively.

Conclusions

Collectively, the findings suggest that students’ understanding of electrochemistry concepts is relatively weak. Students from both samples shared common difficulties and displayed several alternative conceptions dealing with electrolysis, electricity flow, the voltaic cell and the electrode reactions. Not surprisingly, the students displayed limited consistency in understanding of the concepts in the five categories. This study has implications for teaching and learning, particularly in classroom discussions using models and computer animations in order to reinforce understanding at the sub-microscopic level.  相似文献

Background and Context: Encouraging undergraduate programming students to think more about their software development processes is challenging. Most programming courses focus on coding skill development and mastering programming language features; subsequently software development processes (e.g. planning, code commenting, and error debugging) are undervalued. Moreover, many of these processes involve tacit thinking that is often seemingly invisible, meaning it can be difficult for teachers to identify and address shortcomings in student processes.

Objective: In this paper, we employ a novel approach called Interpersonal Process Recall (IPR) to encourage students to think more about their software development processes.

Method: We conducted IPR sessions with five undergraduate programming students—we screen captured them working on programming assignments, and then used the screen captures to stimulate reflection. IPR is hallmarked by several key features, namely its developmental (rather than evaluative) focus, and the use of a facilitator to guide reflection in a structured way.

Findings: We found IPR was useful for both the teaching staff and the students, revealing incongruence between the value students placed on certain development processes and what they actually do in practice.

Implications: IPR is a novel approach for shining a light on student software development processes. We hope this paper encourages other practitioners to consider adding IPR to their toolbox of approaches for encouraging students to reflect on their software development processes.  相似文献

Background: As one part of scientific meta-knowledge, students’ meta-modelling knowledge should be promoted on different educational levels such as primary school, secondary school and university. This study focuses on the assessment of university students’ meta-modelling knowledge using a paper–pencil questionnaire.

Purpose: The general purpose of this study was to assess and to describe university students’ meta-modelling knowledge. More specifically, it was analysed to what extent the meta-modelling knowledge, as expressed in a questionnaire, depends on the scientific discipline to which university students relate their answer and the concrete model to which they refer while answering.

Sample: N = 184 students from one German university voluntarily participated in this study.

Design and methods: The questionnaire was developed based on a theoretical framework for model competence and includes constructed response items asking about the purpose of models, ways for testing models and reasons for changing models. Students written answers were first analysed qualitatively based on the theoretical framework to decide whether they expressed advanced understandings or not. Further analyses then were conducted quantitatively.

Results: Findings suggest that only few university students possess an advanced meta-modelling knowledge. However, significant more students who relate their answers to the STEM-disciplines expressed advanced understandings than those who referred to social sciences or linguistics/philology. Furthermore, university students who expressed an advanced meta-modelling knowledge referred to rather abstract kinds of models in order to explain their view.

Conclusions: The present study supports the assumption that meta-modelling knowledge may be situated and contextualised. Both the scientific discipline and the concrete model to which university students refer seem to be relevant item features influencing university students’ expressed meta-modelling knowledge. Implications for assessment and teaching are discussed in the article.  相似文献

Research in nature of science (NOS) among Asia-Pacific countries such as Singapore is arguably scarce. This study aimed to survey Singaporean secondary school students’ views of NOS with a newly developed instrument named Students’ Views of Nature of Science (SVNOS), which included various key aspects of NOS that are generally agreed upon by the science education community. Moreover, the relations between some demographic factors, including gender and grade, and students’ views of NOS were explored.

Sample, design and method

In total, 359 Singaporean seventh and eighth graders were invited to participate in this survey. The reliability, validity and structure of the SVNOS instrument were ensured by confirmatory factor analysis. A two-way multivariate analysis of variance was then conducted to determine the interaction effects between the gender variable and the grade-level variable.

Results and conclusion

The results indicated that the SVNOS instrument is reliable and valid to assess students’ views of NOS regarding seven distinct NOS dimensions. The male students were more prone to have constructivist-oriented views of NOS in the most of the SVNOS dimensions, while the female students conveyed more non-objective views of NOS. In addition, the eighth graders revealed more empiricist-oriented views of NOS than the seventh graders in several SVNOS dimensions. This result seems to contradict the results of previous studies that students’ views of NOS may reflect a developmental trend with their increasing educational experiences.  相似文献

Careers in dairy: adolescents perceptions and attitudes   总被引：1，自引：0，他引：1  
ABSTRACT

Purpose: This paper examines the attitudes and perceptions of Irish adolescents towards potential careers in dairy farming within the context of generational renewal for a dynamic agri-food sector.

Design/methodology/approach: The lens of occupational choice theory was used to present a framework within which potential careers are considered. A questionnaire-survey was undertaken with 490 Irish adolescents (15–18 yrs).

Findings: While parents have the greatest influence on the career choices of adolescents, there was a positive correlation between studying agricultural science in school and considering an agricultural related career. Adolescent's attitudes towards careers in dairy farming were subject to perceptions about gender, farm ownership, potential income and work-life balance. There was a high degree of openness to gaining work experience on dairy farms.

Practical implications: With an increased interest in agricultural science in second level schools in Ireland, the findings point to opportunities to influence awareness and attitudes of adolescents and their parents about career possibilities in dairy farming and to encourage both familial and non-familiar generational renewal.

Theoretical implications: The paper contributes an understanding of career choices and aspirations in adolescence to add to the growing body of literature on generational renewal in farming.

Originality/value: This paper focuses specifically on dairy farming, providing more detailed information about adolescents’ perceptions of dairy farming careers. The study highlights the positive relationship between studying agricultural science in school and subsequent interest in agricultural related careers. The results indicate that generation renewal in agriculture can be enhanced by giving increased attention to agriculture in school curricula.  相似文献

Background: In research on design-based learning (DBL), inadequate attention is paid to the role the teacher plays in supervising students in gathering and applying knowledge to design artifacts, systems, and innovative solutions in higher education.

Purpose: In this study, we examine whether teacher actions we previously identified in the DBL literature as important in facilitating learning processes and student supervision are present in current DBL engineering practices.

Sample: The sample (N=16) consisted of teachers and supervisors in two engineering study programs at a university of technology: mechanical and electrical engineering. We selected randomly teachers from freshman and second-year bachelor DBL projects responsible for student supervision and assessment.

Design and method: Interviews with teachers, and interviews and observations of supervisors were used to examine how supervision and facilitation actions are applied according to the DBL framework.

Results: Major findings indicate that formulating questions is the most common practice seen in facilitating learning in open-ended engineering design environments. Furthermore, other DBL actions we expected to see based upon the literature were seldom observed in the coaching practices within these two programs.

Conclusions: Professionalization of teachers in supervising students need to include methods to scaffold learning by supporting students in reflecting and in providing formative feedback.  相似文献

Background and purpose:

The purpose of this study was to investigate the comparative effects of a prediction/discussion-based learning cycle (HPD-LC), conceptual change text (CCT) and traditional instruction on 10th grade students’ understanding of genetics concepts.

Sample:

Participants were 112 10th basic grade male students in three classes of the same school located in an urban area. The three classes taught by the same biology teacher were randomly assigned as a prediction/discussion-based learning cycle class (n?=?39), conceptual change text class (n?=?37) and traditional class (n?=?36).

Design and method:

A quasi-experimental research design of pre-test–post-test non-equivalent control group was adopted. Participants completed the Genetics Concept Test as pre-test–post-test, to examine the effects of instructional strategies on their genetics understanding. Pre-test scores and Test of Logical Thinking scores were used as covariates.

Results:

The analysis of covariance showed a statistically significant difference between the experimental and control groups in the favor of experimental groups after treatment. However, no statistically significant difference between the experimental groups (HPD-LC versus CCT instruction) was found.

Conclusions:

Overall, the findings of this study support the use of the prediction/discussion-based learning cycle and conceptual change text in both research and teaching. The findings may be useful for improving classroom practices in teaching science concepts and for the development of suitable materials promoting students’ understanding of science.  相似文献
