Curriculum developers and researchers have promoted context-based programmes to arrest waning student interest and participation in the enabling sciences at high school and university. Context-based programmes aim for student connections between scientific discourse and real-world contexts to elevate curricular relevance without diminishing conceptual understanding. This interpretive study explored the learning transactions in one 11th grade context-based chemistry classroom where the context was the local creek. The dialectic of agency/structure was used as a lens to examine how the practices in classroom interactions afforded students the agency for learning. The results suggest that first, fluid transitions were evident in the student–student interactions involving successful students; and second, fluid transitions linking concepts to context were evident in the students' successful reports. The study reveals that the structures of writing and collaborating in groups enabled students' agential and fluent movement between the field of the real-world creek and the field of the formal chemistry classroom. Furthermore, characteristics of academically successful students in context-based chemistry are highlighted. Research, teaching, and future directions for context-based science teaching are discussed.  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

Even though several studies have reported positive attitudinal outcomes from context-based chemistry programs, methodological obstacles have prevented researchers from comparing satisfactorily the chemistry-learning outcomes between students who experience a context-based program with those who experience a content-driven program. In this narrative inquiry we are able to address the question: how do the recalled experiences of a student and her teacher in context-based and concept-based chemistry programs compare? From the student’s unique perspective of experiencing both programs with the same teacher, we have constructed our collective account around four themes; namely, the extent to which the student makes connections between chemistry concepts and real-world contexts, developing research independence through engaging in extended experimental investigations related to contexts, learning chemistry concepts through contexts, and conceptual sequencing in a context-based program. The student reported real-world connections between chemistry concepts and contexts, found her engagement in the context-driven tasks interesting and productive, and identified connected sequences of concepts across the contexts studied. Despite difficulties for teachers who are required to shift pedagogies, the student’s lived experiences and outcomes from a context-based program provide some encouragement in working through these issues.  相似文献

Context-based science courses stimulate students to reconstruct the information presented by connecting to their prior knowledge and experiences. However, students need support. Formative assessments inform both teacher and students about students’ knowledge deficiencies and misconceptions and how students can be supported. Research on formative assessments suggests a positive impact on students’ science achievement, although its success depends on how the formative assessment is implemented in class. The aim of this study was to provide insights into the effects of formative assessments on achievement during a context-based chemistry course on lactic acid. In a classroom action research setting, a pre-test/post-test control group design with switching replications was applied. Student achievement was measured in two pre-tests, two post-tests and a retention test. Participants were Grade 9 students from one secondary school in the Netherlands. Repeated-measures analysis showed a significant effect of formative assessments on students’ achievement. During the implementation of the formative assessments, intriguing discussions emerged between students, between students and teacher, and between teachers. Adding formative assessments to context-based approaches reinforces their strength to meet with the current challenges of chemistry education. Formative assessments affect students’ achievement positively and stimulate feedback between students and teacher(s).  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

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

This study examined early childhood educators' perceptions about nature, science, and environmental education. Preservice early childhood teachers (n = 195) and early childhood professionals currently practicing in the field (n = 162) rated the importance of providing specific nature/science experiences for young children, the importance of specific nature/science learning outcomes, and their confidence implementing specific activities. Research Findings: Consistent with our hypotheses, both professionals and students rated the curricular domain of nature/science as the least important for young children in terms of experiences and learning outcomes in comparison to other curricular domains. Similarly, both professionals and students reported that they were least confident implementing nature/science activities compared to activities in other curricular domains. Qualitative analysis of open-ended questions yielded themes related to definitions of nature, specific activities in and about nature that can promote children's learning and development, and what educators need to know and be able to do in order to be effective “nature educators.” Practice or Policy: Preservice and in-service teacher professional development would benefit from (a) the inclusion of content on nature, science, and environmental education, including the interrelatedness of human and natural systems; (b) a focus on place-based education and/or emergent curriculum; and (c) the provision of experiences in nature that help teachers to develop confidence implementing activities in nature.

Context-based curriculum reforms in chemistry education are thought to bring greater diversity to the ways in which chemistry teachers organize their teaching. First and foremost, students are expected to perceive this diversity. However, empirical research on how students perceive their teacher's teaching in context-based chemistry classrooms, and whether this teaching differs from traditional chemistry lessons, is scarce. This study aims to develop our understanding of what teaching looks like, according to students, in context-based chemistry classrooms compared with traditional chemistry classrooms. As such, it might also provide a better understanding of whether teachers implement and attain the intentions of curriculum developers. To study teacher behaviour we used three theoretical perspectives deemed to be important for student learning: a content perspective, a learning activities perspective, and an interpersonal perspective. Data were collected from 480 students in 24 secondary chemistry classes in the Netherlands. Our findings suggest that, according to the students, the changes in teaching in context-based chemistry classrooms imply a lessening of the emphasis on fundamental chemistry and the use of a teacher-centred approach, compared with traditional chemistry classrooms. However, teachers in context-based chemistry classrooms seem not to display more ‘context-based’ teaching behaviour, such as emphasizing the relation between chemistry, technology, and society and using a student-centred approach. Furthermore, students in context-based chemistry classrooms perceive their teachers as having less interpersonal control and showing less affiliation than teachers in traditional chemistry classrooms. Our findings should be interpreted in the context of former and daily experiences of both teachers and students. As only chemistry is reformed in the schools in which context-based chemistry is implemented, it is challenging for both students and teachers to deal with these reforms.  相似文献

Curriculum discourse focuses understandably, on the formal and enacted curriculum; however, studies demonstrate that much of individuals’ waking hours are spent in task-unrelated thinking and mind-wandering. No less, this pervasive phenomenon has been shown to affect us in many ways that can be linked to education. This paper examines this null-hidden inner curriculum that is enacted within students’ minds when they are not attentive to the formal/enacted curriculum. Drawing on a review of research in cognitive science, the paper develops a theory of ‘the mind as a curriculum deliberator’ and explains how the mind can be seen as ‘schooling itself’. Different states of mind such as mind-wandering, rumination and mindfulness are discussed in terms of their educational effects and a systematic framework that renders them in curricular terms is suggested. Based on this analysis, the paper aims to mobilize this inner curriculum from opaqueness and absence to a more explicit presence in curricular discourse, in an attempt to broaden our understanding of how the mind can both enhance and hinder education.  相似文献

ABSTRACT

Since the 1990s, the low number of students choosing to study science and technology in higher education has been on the societal agenda and many initiatives have been launched to promote awareness regarding career options. The initiatives particularly focus on increasing enrolment in the engineering programmes. This article describes and compares eight European initiatives that have been established and operated by universities (and in some cases through collaboration with other actors in society). Each initiative is summarised in a short essay that discusses motivation, organisation, pedagogical approach, and activities. The initiatives are characterised by comparing the driving forces behind their creation, how the initiative activities relate to the activities at the university, size based on the number of participants and cost per participant and pedagogical framework. There seem to be two main tracks for building outreach activities, one where outreach activities are based on the university's normal activities, and one where outreach activities are designed specifically for the visiting students.  相似文献

Is it still possible to combine two programmes of study in higher education, and if so, what are the characteristics of these double‐students and what kind of obstacles do they face? In the Netherlands, about 10 percent of students in university education take two studies at the same time.

Different theoretical approaches offer hypotheses to explain the choice of students for a second study, compared to students who pursue the regular one‐study programme. Human capital as well as financial (socio‐economic) capital theory provides some insights in this choice process. Education programme‐related factors, as well as motivational and (social and academic) integration (Tinto, 1987 Tinto V 1987 Leaving College: Rethinking the Causes and Cures of Student Attrition Chicago The University of Chicago Press  [Google Scholar]) factors, will possibly be important determinants for pursuing one or two study programmes in higher education.  相似文献

ABSTRACT

In science education, context-based learning is mostly based on problem-oriented tasks [Gilbert, J. K. (2006). On the nature of “context” in chemical education. International Journal of Science Education, 28(9), 957–976]. Therefore, a relevant question is, how do students integrate the information given in the task into their problem-solving process? The basic assumption is that there is a transition from the situation described in the task to a science model needed to solve the problem [Mestre, J. (2002). Probing adults’ conceptual understanding and transfer of learning via problem posing. Journal of Applied Developmental Psychology, 23(1), 9–50]. The transition needs to be described by parameters of the situation, the science model and the transition process itself. This investigation focuses on the influence of these three elements on the problem-solving process to understand variations in performance [Bennett, J., Lubben, F., & Hogarth, S. (2007). Bringing science to life: A synthesis of the research evidence on the effects of context-based and STS approaches to science teaching. Science Education, 91(3), 347–370]) and the interaction with interest. Despite the large body of research on the mutual influence of context-based problem-solving and interest, research attempting to examine their interplay regarding performance is still lacking. We conducted a hierarchical regression analysis with 178 participants from German high-track schools to investigate three parameters with regard to their influence on affective variables and successful problem-solving: contextualisation of the situation described in the task; the complexity of the scientific model underlying the task; and transparency, which assesses whether and how the learner can identify this model [Löffler, P., & Kauertz, A. (2015). Modellanwendung in kontextualisierten Problemlöseaufgaben [Applying models in contextualised problem solving tasks]. In S. Bernholt (Ed.), Heterogenität und Diversität - Vielfalt der Voraussetzungen im naturwissenschaftlichen Unterricht (Vol. 35, pp. 648–650). Kiel: IPN; Durik, A., & Harackiewicz, J. (2007). Different strokes for different folks: How individual interest moderates the effects of situational factors on task interest. Journal of Educational Psychology, 99(3), 597–610)]. Our findings suggest that these parameters have different effects on how interest is triggered and maintained. Aspects of transparency exhibit small effects on successful problem-solving processes. The results support the assumption that the transition process is the main aspect of context-based problem-solving and can therefore be operationalised as the use of elements of the scientific model in students’ statements. Surprisingly, the usage of such elements cannot be sufficiently explained by pre-knowledge or cognitive abilities.  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

We investigated curricular and pedagogical innovations in an undergraduate science methods course for elementary education majors at the University of Maryland. The goals of the innovative elementary science methods course included: improving students’ attitudes toward and views of science and science teaching, to model innovative science teaching methods and to encourage students to continue in teacher education. We redesigned the elementary science methods course to include aspects of informal science education. The informal science education course features included informal science educator guest speakers, a live animal demonstration and a virtual field trip. We compared data from a treatment course (n = 72) and a comparison course (n = 26). Data collection included: researchers’ observations, instructors’ reflections, and teacher candidates’ feedback. Teacher candidate feedback involved interviews and results on a reliable and valid Attitudes and Beliefs about the Nature of and the Teaching of Science instrument. We used complementary methods to analyze the data collected. A key finding of the study was that while benefits were found in both types of courses, the difference in results underscores the need of identifying the primary purpose for innovation as a vital component of consideration.  相似文献

Expectancy-value motivation profiles were identified in a sample of US ninth-grade students in 2009 (n = 19,259) using latent profile analysis. Of four distinct profiles, two were high, one typical, and one low in math and in science. In each area, the two high profiles were distinguished by (1) high self-efficacy with lower utility value and (2) high utility value with lower self-efficacy. High-ability was identified by a math score at least one standard deviation above the mean within the race/ethnicity group. Forty-one percent of high-ability students had high math motivation, while only 27% had high science motivation. Evidence of disidentification was observed. Some high-ability students had low motivation in math (15%) and science (28%). Implications for talent development and gifted education are discussed.  相似文献

ABSTRACT

The aim of this study is to provide an understanding of context-based inquiry teaching within a humanistic perspective on science education by studying pre-service teachers’ beliefs about inquiry and their implementations of inquiry in their context-based teaching sequences. Therefore, five pre-service teachers enrolled in a university undergraduate course called ‘Inquiry-based chemistry education II’ (5 ECTS) were involved in an empirical case study. The pre-service teachers’ implementations of inquiry were studied from their reports on self-designed context-based inquiry teaching sequences for students age 13–15, and their beliefs by interviewing them after the course. The results indicate that the most frequent aspects of inquiry, which were implemented, were that inquiry (i) includes a context, (ii) is a way to act, (iii) is a way to think, and (iv) includes source/information evaluation and argumentation. The pre-service teachers’ beliefs about inquiry were shown to reflect manifold aspects of inquiry, such as the difficulty in explaining it. However, this difficulty in encapsulating inquiry into a clear-cut definition is not necessarily an impediment to inquiry-based teaching. Furthermore, inquiry is inherently context-bound, and context-based teaching requires extra-situational knowledge from the context and not only declarative knowledge from science. This should be considered to support effective professional development.  相似文献

The population of urban migrants in developing countries has received little specific notice within the field of adult education, although, because of its size and importance to the economic and social development of much of the world, this group deserves significant attention. Examination of urban migrants as learners provides important insight for policies and programmes that support developing their creative potential, building on individual and community strengths. Two characteristics of the motivation and learning needs of urban migrants stand out. First, individual characteristics relating to personality or motivation somehow differentiate migrants from non‐migrants, beyond generalized economic or macro‐level factors that affect migration decisions. On the other hand, it appears that group learning processes that incorporate the participation of the members and build on their networks, motivation, and coping skills, are particularly effective. Both of these aspects are important in identifying appropriate policies and programmes that stimulate the positive potential of this group. This paper examines evidence related to the demographic and cognitive characteristics of the urban migrant population in developing countries, how these relate to the learning tasks facing this group, and the implications for successful adult education programmes. In addition, these characteristics have implications for broader policies designed to take advantage of the role that communities of urban migrants can play, within a more participative development approach.  相似文献

Honours programmes have become part of higher education systems around the globe, and an increasing number of students are enrolled in such programmes. So far, effects of these programmes are largely under-researched. Two gaps in previous research on the effects of such programmes were addressed: (1) most studies lack a comparable control group of students not enrolled in honours programmes and (2) few studies have longitudinally investigated effects of honours programmes on student characteristics other than academic achievement. By using propensity score matching, the current study investigated the effects of Dutch honours programmes on students’ ability, motivation, creativity and academic achievement. Students’ self-perceived ability, perseverance, mastery orientation, performance orientation, intellectual curiosity and self-efficacy, as well as students’ gender and study grades were used to match undergraduate honours students to non-honours students (N?=?94). Results showed no overall differences in ability, motivation and creativity halfway into the honours programme, although honours students seemed to slightly increase in intellectual curiosity, while non-honours students tended to decrease in mastery orientation. Outcomes of the study give rise to considerations about the role of honours programmes in curricula.  相似文献

Research on predictors of achievement in science is often targeted on more traditional content-based assessments and single student characteristics. At the same time, the development of skills in the field of scientific inquiry constitutes a focal point of interest for science education. Against this background, the purpose of this study was to investigate to which extent multiple student characteristics contribute to skills of scientific inquiry. Based on a theoretical framework describing nine epistemological acts, we constructed and administered a multiple-choice test that assesses these skills in lower and upper secondary school level (n?=?780). The test items contained problem-solving situations that occur during chemical investigations in school and had to be solved by choosing an appropriate inquiry procedure. We collected further data on 12 cognitive, motivational, and sociodemographic variables such as conceptual knowledge, enjoyment of chemistry, or language spoken at home. Plausible values were drawn to quantify students’ inquiry skills. The results show that students’ characteristics predict their inquiry skills to a large extent (55%), whereas 9 out of 12 variables contribute significantly on a multivariate level. The influence of sociodemographic traits such as gender or the social background becomes non-significant after controlling for cognitive and motivational variables. Furthermore, the performance advance of students from upper secondary school level can be explained by controlling for cognitive covariates. We discuss our findings with regard to curricular aspects and raise the question whether the inquiry skills can be considered as an autonomous trait in science education research.  相似文献

ABSTRACT

Context-based approaches can bridge the gap between abstract, difficult science concepts and the world students live in. However, the relevance of specific contexts to different groups of learners, and its stability over time, have not been extensively explored. This study used four datasets, collected in different formal and informal settings, to examine which types of contexts could capture the interest of many students and remain so for many years. In the formal setting, responses to closed-ended questionnaires in which 4–12th graders indicated their interest in studying the answers to science questions were compared. Over 700 questionnaires collected in 2007 were compared to over 1600 questionnaires collected in 2016. To document the stability of children’s interest in informal science learning settings we compared over 1600 science questions sent to a TV science show in 2004 with over 7000 science questions submitted to a commercial exhibition in 2014. Although there were some differences across ages, students’ interest in science remained relatively stable over the 10 years. In the formal setting, this similarity was reflected in the significant linear relationship between the two databases (r?=?0.917) with regard to the questions students found interesting. In the informal setting, there was a striking similarity in the proportions of spontaneous questions in biology, astrophysics, Earth Science and chemistry. Based on the findings of this study and the literature we recommended, frequently asked questions are a valuable resource for context-based teaching which can serve to identify contexts that enhance the relevance of science in students’ lives.  相似文献
