Context-based chemistry education aims to improve student interest and motivation in chemistry by connecting canonical chemistry concepts with real-world contexts. Implementation of context-based chemistry programmes began 20 years ago in an attempt to make the learning of chemistry meaningful for students. This paper reviews such programmes through empirical studies on six international courses, ChemCom (USA), Salters (UK), Industrial Science (Israel), Chemie im Kontext (Germany), Chemistry in Practice (The Netherlands) and PLON (The Netherlands). These studies are categorised through emergent characteristics of: relevance, interest/attitudes/motivation and deeper understanding. These characteristics can be found to an extent in a number of other curricular initiatives, such as science-technology-society approaches and problem-based learning or project-based science, the latter of which often incorporates an inquiry-based approach to science education. These initiatives in science education are also considered with a focus on the characteristics of these approaches that are emphasised in context-based education. While such curricular studies provide a starting point for discussing context-based approaches in chemistry, to advance our understanding of how students connect canonical science concepts with the real-world context, a new theoretical framework is required. A dialectical sociocultural framework originating in the work of Vygotsky is used as a referent for analysing the complex human interactions that occur in context-based classrooms, providing teachers with recent information about the pedagogical structures and resources that afford students the agency to learn.  相似文献

ABSTRACT

In this paper we explore the views and opinions of four secondary education science teachers regarding the teaching of scientific competences. Their views were gathered in the context of a training programme in which they had to design, implement, and assess their own teaching unit for developing students’ scientific competences by means of context-based learning. Analysis of the data yielded a set of 14 categories distributed across 5 areas: scientific competence and context-based teaching; the teacher and his/her professional environment; implementation in the classroom; development of the teaching unit; and assessment. This process also identified the aspects which teachers believed either facilitated or acted as an obstacle to the development of scientific competences through context-based teaching. We discuss the implications of our findings and suggest ways in which a shift towards a context-based approach to teaching scientific competences can best be achieved, and consider a series of factors related to teachers’ professional identity that may influence this process.  相似文献

ABSTRACT

This qualitative metasynthesis investigated students’ meaningful learning experiences amid andragogical teacher education programmes. The programmes catered to the specific learning needs of adult students in the context of university-based teacher education. This study aimed to provide a wider picture of the frames of students’ meaningful learning in andragogical teacher education programmes. The findings revealed three major learning worlds of adult students’ meaningful learning, which formed a common system widening from the professional awakening to the transformative community and agency in society. Based on the findings, this study argues that in andragogical teacher education, which emphasises collaboration and networking in accordance with the current trend in higher education, teacher students may become empowered participants and active agents in society. The findings can be used in planning curricula, and developing programmes of higher education in general and teacher education in particular.  相似文献

ABSTRACT

International education achievement indicators potentially obscure students’ localised experiences of school. This paper examines adolescent purpose to understand what drives students’ learning experiences in high-performance schooling in Singapore. Purpose is a long-term intention to engage with the world in ways meaningful to oneself and to others. Using clinical interviews, the authors analysed students’ perspectives of the purpose of schooling and learning against the tensions of preparing students for performance-focused outcomes in schools. Findings indicated purpose clusters with prevalent self-oriented academic achievement goals. About one-third of the students with forms of support had nascent beyond-the-self life goals. To think about teaching and learning in a more integrated manner, this study shows it is important to look closely into students’ learning experiences, as these provide critical insights into how policies are implemented in schools, and how curricula can be made significant and meaningful in a more humanising vision of what schools might become.  相似文献

ABSTRACT

Many studies in science education acknowledge the positive effects of context-based learning on students’ interest and attitudes. However, little is known about the design criteria of contextual situations generating these effects and how facets of students’ situational interest are affected while learning in a contextualised setting. This paper ties in with this initial situation and reports results of two projects analysing the influence of context characteristics on students’ situational interest, referring to contexts as task parameters in the first project and as learning activities in the second. In the first project, everyday related and unique contexts are compared, and the effects of different contextual topics on student learning are investigated. Particularly, regarding the feeling- and value-related valence of situational interest, the results of different studies will be compared and interpreted. The second project investigated structures of interest related to activities along an adapted version of the ‘RIASEC’-model for different content areas and age groups. The chosen contents were embedded in personal as well as societal and professional context settings. Finally, we summarise the relevance of the different models, results and instruments to better understand different notions of interest and outline implications for further studies about teaching that improves student learning.  相似文献

ABSTRACT

In order to create conditions for students’ meaningful and rigorous intellectual engagement in science classrooms, it is critically important to help science teachers learn which strategies and approaches can be used best to develop students’ scientific literacy. Better understanding how science teachers’ instructional practices relate to student achievement can provide teachers with beneficial information about how to best engage their students in meaningful science learning. To address this need, this study examined the instructional practices that 99 secondary biology teachers used in their classrooms and employed regression to determine which instructional practices are predictive of students’ science achievement. Results revealed that the secondary science teachers who had well-managed classroom environments and who provided opportunities for their students to engage in student-directed investigation-related experiences were more likely to have increased student outcomes, as determined by teachers’ value-added measures. These findings suggest that attending to both generic and subject-specific aspects of science teachers’ instructional practice is important for understanding the underlying mechanisms that result in more effective science instruction in secondary classrooms. Implications about the use of these observational measures within teacher evaluation systems are discussed.  相似文献

ABSTRACT

Caribbean students are repeatedly engaged in rigid forms of writing to meet the requirements of external exams, which often leads to negative attitudes to writing. With current shifts to multimodal and multi-literate texts to engage students’ multiple literacies in learning, students’ creation of graphic novels in Caribbean English classrooms can enable their engagement in meaningful creative writing. To illustrate this, I draw on my recent experiences with four inner-city boys at a Jamaican high school who showed marked improvement in their attitudes and their creative writing skills after creating graphic novels. The preliminary findings from my research suggest a need for more personalised learning strategies and for more opportunities for students to use their home language in Caribbean classrooms.  相似文献

Background and purpose : Knowing how students learn physics is a central goal of physics education. The major purpose of this study is to examine the strength of the predictive power of students’ epistemic views and conceptions of learning in terms of their approaches to learning in physics. Sample, design and method : A total of 279 Taiwanese high school students ranging from 15 to 18?years old participated in this study. Three questionnaires for assessing high school students’ epistemic views on physics, conceptions of learning physics and approaches to learning physics were developed. Step-wise regression was performed to examine the predictive power of epistemic views on physics and conceptions of learning physics in terms of their approaches to learning physics. Results and conclusion: The results indicated that, in general, compared to epistemic views on physics, conceptions of learning physics are more powerful in predicting students’ approaches to learning physics in light of the regression models. That is, students’ beliefs about learning, compared with their beliefs about knowledge, may be more associated with their learning approaches. Moreover, this study revealed that the higher-level conceptions of learning physics such as ‘Seeing in a new way’ were more likely to be positively correlated with the deep approaches to learning physics, whereas the lower-level conceptions such as ‘Testing’ were more likely to positively explain the surface approaches, as well as to negatively predict the deep approaches to learning physics.  相似文献

The committees for the current Dutch context-based innovation in secondary science education employed teachers to design context-based curriculum materials. A study on the learning of science teachers in design teams for context-based curriculum materials is presented in this paper. In a correlation study, teachers with (n?=?25 and 840 students) and without (n?=?8 and 184 students) context-based curriculum material design experience were compared on context-based competence. Context-based competence comprises context handling, regulation, emphasis, design, and school innovation. Context-based teaching competence was mapped using both qualitative and quantitative research methods in a composite instrument. Due to the differences in design team set-up for different science subjects, teachers with design experience from different science subjects were also compared on their context-based competence. It was found that teachers with design experience showed more context-based competence than their non-designing colleagues. Furthermore, teachers designing for biology showed more context-based competence than their peers from other science subjects.  相似文献

Background: Recent research and curriculum reforms have indicated the need for diversifying teaching approaches by drawing upon student interest and engagement in ways which makes learning science meaningful. Purpose: This study examines the integration of informal/free choice learning which occurred during learning experiences outside school (LEOS) with classroom learning using digital technologies. Specifically, the digital technologies comprised a learning management system (LMS), Moodle, which fits well with students’ lived experiences and their digital world. Design and Method: This study examines three out-of-school visits to Informal Science Institutes (ISI) using a digitally integrated fieldtrip inventory (DIFI) Model. Research questions were analysed using thematic approach emerging along with semi-structured interviews, before, during and after the visit, and assessing students’ learning experiences. Data comprised photographs, field notes, and unobtrusive observations of the classroom, wiki postings, student work books and teacher planning diaries. Results: We argue, that pre- and post-visit planning using the DIFI Model is more likely to engage learners, and the use of a digital learning platform was even more likely to encourage collaborative learning. The conclusion can also be drawn that students’ level of motivation for collaborative learning positively correlates with their improvement in academic achievement.  相似文献

ABSTRACT

There is growing interest in how to engage middle school students in science to improve their enthusiasm for science and to arrest the decline in uptake in the senior years. Also, there is interest in improving students’ application of science to real-life situations, a requirement for international tests. One approach that offers hope for improving students’ connections between concepts and context is the context-based approach. Context-based units that connect canonical science with the real-world of the student’s local community have been trialled in the senior years but are new in the middle years. Research in senior classes has shown that students who were taught through a context-based approach demonstrated fluid transitions between the context and concepts in written work and student-student conversations. In the current ethnographic study we built on our previous work and investigated how students make connections between the environmental science concepts and the context of the weekly visits to the local creek. Students were immersed in the real-world context by completing an 11-week environmental science unit that required assessment of the health of a creek. Two assertions emerged; firstly, student-student conversations at the creek afforded students the opportunity for interconnections between environmental science concepts and the context (defined as resonance); and secondly, students’ written reports about the health of the creek demonstrated resonance. Furthermore, group work encouraged students the agency to complete sets of tasks that privileged visually obvious environmental science concepts such as pollution, identification of plants/animals or turbidity/flow rate.  相似文献

There is on-going international interest in the relationships between assessment instruments, students’ understanding of science concepts and context-based curriculum approaches. This study extends earlier research showing that students can develop connections between contexts and concepts – called fluid transitions – when studying context-based courses. We provide an in-depth investigation of one student’s experiences with multiple contextual assessment instruments that were associated with a context-based course. We analyzed the student’s responses to context-based assessment instruments to determine the extent to which contextual tests, reports of field investigations, and extended experimental investigations afforded her opportunities to make connections between contexts and concepts. A system of categorizing student responses was developed that can inform other educators when analyzing student responses to contextual assessment. We also refine the theoretical construct of fluid transitions that informed the study initially. Implications for curriculum and assessment design are provided in light of the findings.  相似文献

ABSTRACT

Standards-based grading (SBG) tightly links student assessment to course learning objectives, providing students with meaningful feedback. A well-designed SBG system should ease first-year engineering (FYE) students’ transition to tertiary education by setting clear expectations and enabling self-monitoring of learning progress. However, when students fail to access and use resources and feedback to guide their learning, the effort to construct an SBG system is not commensurate with the student learning benefits. FYE students in a course using SBG self-reported their access to and use of SBG resources and feedback to guide their work on assignments and prepare for exams. Access and use was low at the start or the semester but improved mid-semester around exam time. In a subsequent semester, strategies were employed to increase students’ engagement with the SBG system. Students’ access and use was significantly higher in the beginning of the semester. Insights on students’ engagement related to course management decisions are offered.  相似文献

ABSTRACT

Promoting preservice science teachers’ experimentation competency is required to provide a basis for meaningful learning through experiments in schools. However, preservice teachers show difficulties when experimenting. Previous research revealed that cognitive scaffolding promotes experimentation competency by structuring the learning process, while metacognitive and multimedia support enhance reflection. However, these support measures have not yet been tested in combination. Therefore, we decided to use cognitive scaffolding to support students’ experimental achievements and supplement it by metacognitive and multimedia scaffolds in the experimental groups. Our research question is to what extent supplementing cognitive support by metacognitive and multimedia scaffolding further promotes experimentation competency. The intervention has been applied in a two-factorial design to a two-month experimental course for 63 biology teacher students in their first bachelor year. Pre-post-test measured experimentation competency in a performance assessment. Preservice teachers worked in groups of four. Therefore, measurement took place at group level (N?=?16). Independent observers rated preservice teachers’ group performance qualitatively on a theory-based system of categories. Afterwards, experimentation competency levels led to quantitative frequency analysis. The results reveal differing gains in experimentation competency but contrary to our hypotheses. Implications of combining scaffolding measures on promoting experimentation competency are discussed.  相似文献

The current trend in science curricula is to adopt a context-based pedagogical approach to teaching. New study materials for this innovation are often designed by teachers working with university experts. In this article, it is proposed that teachers need to acquire corresponding teaching competences to create a context-based learning environment. These competences comprise an adequate emphasis, context establishment, concept transfer, support of student active learning, (re-)design of context-based materials, and assistance in implementation of the innovation. The implementation of context-based education would benefit from an instrument that maps these competences. The construction and validation of such an instrument (mixed-methods approach) to measure the context-based learning environment is described in this paper. The composite instrument was tested in a pilot study among 8 teachers and 162 students who use context-based materials in their classrooms. The instrument’s reliability was established and correlating data sources in the composite instrument were identified. Various aspects of validity were addressed and found to be supported by the data obtained. As expected, the instrument revealed that context-based teaching competence is more prominently visible in teachers with experience in designing context-based materials, confirming the instrument’s validity.  相似文献

Context-based chemistry education aims at making connections between real life and the scientific content of chemistry courses. The purpose of this study was to evaluate context-based chemistry studies. In looking for the context-based chemistry studies, the authors entered the keywords ??context-based??, ??contextual learning?? and ??chemistry education?? in well-known databases (i.e. Academic Search Complete, Education Research Complete, ERIC, Springer LINK Contemporary). Further, in case the computer search by key words may have missed a rather substantial part of the important literature in the area, the authors also conducted a hand search of the related journals. To present a detailed thematic review of context-based chemistry studies, a matrix was used to summarize the findings by focusing on insights derived from the related studies. The matrix incorporates the following themes: needs, aims, methodologies, general knowledge claims, and implications for teaching and learning, implications for curriculum development and suggestions for future research. The general knowledge claims investigated in this paper were: (a) positive effects of the context-based chemistry studies; (b) caveats, both are examined in terms of students?? attitudes and students?? understanding/cognition. Implications were investigated for practice in context-based chemistry studies, for future research in context-based chemistry studies, and for curriculum developers in context-based chemistry studies. Teachers of context-based courses claimed that the application of the context-based learning approach in chemistry education improved students?? motivation and interest in the subject. This seems to have generated an increase in the number of the students who wish to continue chemistry education at higher levels. However, despite the fact that the majority of the studies have reported advantages of context-based chemistry studies, some of them have also referred to pitfalls, i.e. dominant structure of out-of-school learning, tough nature of some chemistry topics, and teacher anxiety of lower-ability students.  相似文献

ABSTRACT

A critical issue in educator preparation is how to ascertain if program graduates are sufficiently prepared to be effective through the acquisition of meaningful evidence of graduates’ impact on their students. Challenges to proving specific impact of educator-preparation programs on student learning include identifying and following program completers as they move into diverse teaching environments. Barriers include lack of access to measures such as students’ achievement scores and work samples. This article puts the research on educator-preparation-program accountability into perspective and provides a discussion about whether or not we have the capacity at this moment in time to access meaningful data about and proof of teacher impact.  相似文献

Abstract

In meaningful learning tasks the acquisition process is influenced by the way in which the individual learner interprets and encodes the material. Early attempts to recall written materials largely determine subsequent retention, even when the learner's errors are corrected. To provide an indication of how information was interpreted and encoded by learners, adult students were asked to write notes on a meaningful prose extract they heard, and they were later asked to attempt recall. Whereas the meaningful items recorded in a subject's notes had a .34 probability of recall one week later, items not recorded in notes were recalled on only .047 of occasions, suggesting that the notes learners make provide a useful indication of the products of individual encoding processes In meaningful verbal learning and memory.  相似文献
