Background: The sophistication of students’ conceptions of science learning has been found to be positively related to their approaches to and outcomes for science learning. Little research has been conducted to particularly investigate students’ conceptions of science learning by laboratory.

Purpose: The purpose of this research, consisting of two studies, was to explore Taiwanese university science-major students’ conceptions of learning science by laboratory (CLSL).

Sample: In Study I, interview data were gathered from 47 university science-major students. In Study II, 287 university science-major students’ responses to a CLSL survey were collected.

Design and methods: In Study I, the interview data were analyzed using the phenomenographic method. Based on the findings derived from Study I, Study II developed an instrument for assessing students’ CLSL by exploratory factor analysis.

Results: Study I revealed six categories of CLSL, including memorizing, verifying, acquiring manipulative skills, obtaining authentic experience, reviewing prior learning profiles, and achieving in-depth understanding. The factor analysis in Study II revealed that the ‘verifying’ category was eliminated, but found another new category of ‘examining prior knowledge.’

Conclusions: This study finally proposes a framework to describe the variations of CLSL, consisting of three features: cognitive orientation, metacognitive orientation, and epistemic orientation. Possible factors influencing students’ CLSL are also discussed.  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

Background: Many international science curriculum documents mandate that students should be able to participate in argument, debate and decision-making about contemporary science issues affecting society. Termed socioscientific issues, these topics provide students with opportunities to use their scientific knowledge to discuss, debate and defend their decisions and to evaluate the arguments of their peers.

Purpose: This study describes the development and trialling of scenarios based on the socioscientific issue of climate change. The scenarios required students to make and justify a decision and were designed to assess students’ argumentation skills.

Sample: A sample of 162 Year 10 students from five schools in Perth, Western Australia participated in this study.

Design and methods: Recent media articles were reviewed to identify relevant contexts for scenarios related to climate change that could be used to develop and assess students’ argumentation skills. In the first phase, students trialled scenarios about wind farms and hydrogen fuel buses using writing frames with scaffolding questions to generate as many reasons as possible to justify their decision. The responses were categorised into themes which were used to prepare a scoring rubric. In the second phase, students generated written arguments about the scenarios to support their decision. The arguments were analysed using both the scoring rubric developed from the first phase and Toulmin’s argumentation pattern of claim, data, backing, qualifier and rebuttal.

Results: Students’ responses to the scaffolded questions were categorised into themes of agriculture, economy, energy, environment, human impact and ethical factors. The themes of economy and the environment predominated with ethical justifications cited infrequently. An analysis of the arguments generated revealed a majority of students’ responses consisted of a claim and data with backings, qualifiers and rebuttals rarely provided.

Conclusions: Scenarios about climate change socioscientific issues can be used by teachers to both develop and assess students’ argumentation skills in classroom settings.  相似文献

Background: Recently, there is a growing interest in independent learning approaches globally. This is, at least in part, due to an increased demand for so-called ‘21st century skills’ and the potential of independent learning to improve student skills to better prepare them for the future.

Purpose: This paper reports a study that explored the effectiveness of two different independent learning approaches: (i) guided independent learning and (ii) unguided independent learning with independent research, in enabling students in an undergraduate Macromolecules course to acquire knowledge in one chemistry context and apply it successfully in another.

Sample: The study involved 144 chemistry students commencing their first term of undergraduate study at a northern university in England. Students completed pre- and post-intervention tests containing 10 diagnostic questions, of which 4 measured students’ knowledge acquisition in one context and 6 measured their ability to apply it in another.

Design and methods: Diagnostic questions had been identified using a Delphi approach. Paired t-tests and chi-square tests were used to analyse the significance of any change in students’ responses to the diagnostic questions and the number of responses evidencing misconceptions, respectively.

Results: Whilst guided independent learning settings were found to improve students’ knowledge and ability to apply that knowledge in novel situations, unguided independent learning had no statistically significant effect. Unguided independent learning was also linked to a statistically significant increase in the number of student misconceptions in one of the diagnostic questions.

Conclusions: The results of this study show that guidance in independent learning activities is a key necessity for effective learning in higher education. This paper has strong relevance and high significance to tertiary STEM education, especially in the light of increased importance of teaching, such as the Teaching Excellence Framework in the UK, and shifts to more independent learning activities.  相似文献

Background: In recent research, affective learning environments and affective support have been receiving increasing attention for their roles in stimulating students’ learning outcomes. Despite its raising importance, little is known about affective support in educational contexts in developing countries. Moreover, international student assessment programmes (e.g. PISA and TIMSS) reveal poor science proficiency of students in most of those countries, which provokes the question of how to make positive changes in students’ perspectives and attitudes in science.

Purpose: In the current study, the purpose was to investigate the relations among perceived teacher affective support (PTAS), academic emotions (academic enjoyment, academic anxiety, and academic hopelessness), academic self-efficacy and behavioural engagement in elementary school science classrooms in Turkey.

Sample: A total of 633 fourth- and fifth-grade students in eight elementary schools in Istanbul, Turkey were participated in the study.

Design and methods: A self-report questionnaire was administered to participating students. The data were analysed using structural equation modelling.

Results: Findings showed that PTAS was both directly and indirectly related to the given variables. PTAS was found to be significantly positively associated with students’ academic enjoyment, academic self-efficacy and behavioural engagement and significantly negatively related to their academic anxiety and academic hopelessness in science classrooms. An important finding is that the total effect of PTAS on behavioural engagement, a factor strongly associated with academic success in all disciplines, was as strong as the effect of students’ perceived academic self-efficacy beliefs in science.

Conclusions: Findings suggest that PTAS may help promoting positive emotions and motivation among students in science classrooms, eventually leading to more desirable attitudes and achievement outcomes in science. Teacher affective support deserves greater recognition from researchers, educational policy-makers, administrators and teachers to build better learning conditions for all students.  相似文献

Background: Reading is an interactive and constructive process of making meaning by engaging a variety of materials and sources and by participating in reading communities at school or in daily life.

Aim: The purpose of this study was to explore the factors affecting digital reading literacy among upper-elementary school students.

Method: A 3-stage stratified cluster sampling was implemented that resulted in a sample of 592 upper-elementary students from 29 classes in 7 schools. Self-Regulated Learning Strategies Assessment (S-RLSA), Digital Reading Literacy Assessment (DRLA), and student reports of their parents’ education backgrounds were used to collect data on the outcome and predictor variables. Interpretation of these data involved two highly regarded statistical techniques. First, structural equation modeling was used to explore relationships amongst the constructs. Second, multi-group invariance (MI) analyses were used to assess the influence of parental education and self-regulated learning strategies on students’ digital reading literacy.

Results: Enriching students’ family learning resources and strengthening their self-regulated learning abilities could have very important influences on promoting upper-elementary school students' digital reading literacy -webpage information retrieval, reading and communication abilities.

Conclusions: This study also provides information on how teachers can address student resources to improve digital reading literacy and self-regulated strategies.  相似文献

Since early 1974, a pilot project for integrated teacher training has been in progress at Oldenburg University. This is currently the only extensive teacher training reform which exist in the German Federal Republic.

All plans for this integrated training program are designed to provide training normally encompassed by the traditional two‐stage programm.

The integrated training program includes:

- studies in the areas of education and social science;

- studies in two major subjects which are later to be taught at school;

- practical studies and activities.

The new model leads to the following degrees:

- nine semesters of study for a Certificate of Qualification for primary and lower‐level secondary school;

- eleven semesters for a Certificate of Qualification for higher‐level secon dary school and the education of exceptional children.

Theoretic training in major subject areas and related didactic training as well as education and social studies take place chiefly in the form of projects. A basic assumption is that interdisciplinary projects which are practice‐ and problemoriented permit a highly desirable integration of theory and practice on the whole.

In the project, contact teachers are an essential link between field practice at school and academic training at the university. Contact teachers are under contact to the university for an extended period of time (generally three years). In place of remunation, their teaching loads are reduced by ten hours per week.

In 1978/79 the project will be put to the test as the first generation of students prepares for State Board Examinations.  相似文献

Background: Complexity models have provided a suitable framework in various domains to assess students’ educational achievement. Complexity is often used as the analytical focus when regarding learning outcomes, i.e. when analyzing written tests or problem-centered interviews. Numerous studies reveal negative correlations between the complexity of a task and the probability of a student solving it.

Purpose: Thus far, few detailed investigations explore the importance of complexity in actual classroom lessons. Moreover, the few efforts made so far revealed inconsistencies. Hence, the present study sheds light on the influence the complexity of students’ and teachers’ class contributions have on students’ learning outcomes.

Sample: Videos of 10 German 8th grade physics courses covering three consecutive lessons on two topics each (electricity, mechanics) have been analyzed. The sample includes 10 teachers and 290 students.

Design and methods: Students’ and teachers’ verbal contributions were coded manual-based according to the level of complexity. Additionally, pre-post testing of knowledge in electricity and mechanics was applied to assess the students’ learning gain. ANOVA analysis was used to characterize the influence of the complexity on the learning gain.

Results: Results indicate that the mean level of complexity in classroom contributions explains a large portion of variance in post-test results on class level. Despite this overarching trend, taking classroom activities into account as well reveals even more fine-grained patterns, leading to more specific relations between the complexity in the classroom and students’ achievement.

Conclusions: In conclusion, we argue for more reflected teaching approaches intended to gradually increase class complexity to foster students’ level of competency.  相似文献

For the present development of teacher training system in Slovenia (Yugoslavia) two trends are characteristic: the prolongation of studies for elementary school teachers (grades 1‐8) from two to four years and an institutional shift of responsibility for subject teacher training from ‘mono‐technical’ (pedagogical academies) to ‘polytechnical’ institutions (different faculties or departments of the universities).

These trends are having important implications for the scope of practical training and its relationship to other parts of the studies. Traditional forms of practical training that had developed at pedagogical academies are being discontinued but the new ones are not yet firmly established.

The existing forms of practical training of student teachers are briefly described (exercises in general professional courses, exercises in classroom observation, teaching attempts and block practice). In addition, the role of teachers of special didactics and the role of practice teachers is analysed.

The pragmatic character of practical training has to be overcome on the basis of systematic attempts to confront students’ subjective theories on teaching and learning, based on experience, with scientific theories throughout the process of their training.

An important prerequisite for the necessary integration of different components of study and especially of theory and practice is cooperation between university teachers of academic, general professional subjects and special didactics. How do we achieve such a cooperation and overcome the negative attitude of teachers of academic subjects toward professional and practical training of students? This remains one of the open problems in the reform of teacher training in Slovenia.  相似文献

The author sees the Hungarian teacher education system as being in a state of transition and development and identifies a number of the planning issues to be faced.

There has existed, traditionally in Hungary, the two routes through teacher‐training familiar to many Western countries, characterised as the e'cole normale/university dichotomy. This has revealed a familiar problem: the older the age‐range for which the student is being trained, the less emphasis on pedagogy in the training.

Hungarian teacher education faces other problems. There is still a shortage of teachers, despite a high level of demand for training; demographic problems weigh heavily.

Attempts at finding solutions through mergers of institutions at different levels meet resistance, and the conflict of values from universities and teachers’ colleges echoes similar debates in, for example, France and Greece. The problems encountered raise a fundamental question: who should decide the nature of the teacher‐training programme: the specialist academics and pedagogues, or the employing community? In Hungary, the debate continues.  相似文献

Background: In developed countries, it is challenging for teachers to select pedagogical practices that encourage students to enrol in science and technology courses in upper secondary school.

Purpose: Aiming to understand the enrolment dynamics, this study analyses sample-based data from Finland’s National Assessment in Science to determine whether pedagogical approaches influence student intention to enrol in upper secondary school physics courses.

Sample: This study examined a clustered sample of 2949 Finnish students in the final year of comprehensive school (15–16 years old).

Methods: Through explorative factor analysis, we extracted several variables that were expected to influence student intention to enrol in physics courses. We applied partial correlation to determine the underlying interdependencies of the variables.

Results: The analysis revealed that the main predictor of enrolment in upper secondary school physics courses is whether students feel that physics is important. Although statistically significant, partial correlations between variables were rather small. However, the analysis of partial correlations revealed that pedagogical practices influence inquiry and attitudinal factors. Pedagogical practices that emphasise science experimentation and the social construction of knowledge had the strongest influence.

Conclusions: The research implies that to increase student enrolment in physics courses, the way students interpret the subject’s importance needs to be addressed, which can be done by the pedagogical practices of discussion, teacher demonstrations, and practical work.  相似文献

This paper reports some data of an ARC funded study of academic staff in a number of disciplines in colleges of advanced education and universities. Generally, more university than college academics scored high on academic motivation, on teaching‐research synergy and promotion of student independence, with college academics scoring higher on good teaching practice. There are disciplinary differences, too.

Slightly more than an average proportion of staff in the Social Sciences report good teaching practices. They are highly committed to promoting student independence, experience a fairly high level of teaching‐research synergy and have high intrinsic academic motivation. There is large‐scale consensus among Arts staff with university Arts academics scoring highest on promoting student independence, academic motivation, and teaching‐research synergy, and academics in CAE Arts departments scoring highest of all on good teaching practices.

Science staff seem to have different academic values and practices. Their academic motivation is about “average”, and fewer science academics report good teaching practices or practices that promote student independence. In their own work they also experience less teaching‐research synergy. Engineering staff show the lowest academic motivation, least commitment to student independence, experience least teaching‐research synergy, and report below average good teaching practices.

Health Science staff are akin to staff in Arts and Social Sciences in areas concerned with students, e.g. good teaching practices and promotion of student independence. In the areas which tap into their values as academics, e.g. academic motivation and teaching‐research synergy, they seem to be more like science and engineering staff.

Commerce/Law staff were on all aspects somewhere in the middle.  相似文献

Background: Microorganisms are very important in day-to-day life, but they are inadequately addressed in the Spanish educational system. It is essential that students are well informed about their characteristics and functions.

Purpose: The study aims to find out primary school students’ perceptions of microorganisms and to analyze whether theoretical or practical teaching interventions produce different levels in student’s learning about this topic.

Sample: The sample consisted of 199 primary students in 2nd (aged 7–8) and 6th (11–12) grades from two public schools in Albacete (Spain).

Design and method: This study uses a pre- and post-intervention questionnaire to evaluate the knowledge of students on the issue of microorganisms. We compare differences by age and two teaching–learning intervention methodologies: theoretical and practical.

Results: Results from the pre-test showed a poor understanding and several misconceptions. Children have a limited and negative view of microorganisms, mainly derived from non-formal learning. Both types of intervention provided an improvement in knowledge, but closed questions did not reveal clear statistically significant differences between methods. Open questions showed how the scientific use of the language and quality of verbalization is much better in the groups that received a practical intervention.

Conclusion: The findings can be a starting point for curriculum planners and for teachers interested in engaging students in science learning.  相似文献

Background Global climate change (GCC) has become one of the most debated socio-scientific issues after an increase in media attention. Recently, there have also been several studies describing students’ and teachers’ alternative conceptions about GCC. Therefore, designing learning environments at the college level that focus on accurate conceptions of GCC has become important in order for pre-service teachers to correct their alternative conceptions. There are, however, a limited number of studies that aim to both increase pre-service teachers’ knowledge about these issues and explore their perceptions of teaching this subject.

Purpose The purpose of this study was to investigate the effects of inquiry-based activities on pre-service teachers’ knowledge about GCC and their perceptions of teaching this subject.

Sample The participants were 102 pre-service middle school mathematics and science teachers who were enrolled in an environmental education course.

Design and methods A one group pre-test–post-test design was employed to identify changes after pre-service teachers engaged in a learning unit on GCC. The inquiry-based GCC unit was implemented during the spring semester at a public university in northeastern Turkey. The unit was implemented over seven sessions. Data were collected through two questionnaires: the ‘GCC content questionnaire’ and the ‘perceptions of teaching GCC questionnaire’. Each questionnaire was administered both before and after implementation of the unit. Content questionnaire responses were analyzed using a paired-samples t-test. Responses to the perceptions of teaching questionnaire were analyzed using inductive open coding.

Results Results indicated that after the implementation the pre-service teachers significantly improved their understanding of GCC across all items in the content questionnaire, saw several benefits of and challenges about teaching GCC, and perceived themselves as better prepared to teach about GCC in their future classrooms.

Conclusions Teacher education programs should integrate inquiry-based GCC instruction to increase pre-service teachers’ knowledge as well as their preparedness to teach about this important planetary issue.  相似文献

Background: Feedback is one of the most significant factors for students’ development of writing skills. For feedback to be successful, however, students and teachers need a common language – a meta-language – for discussing texts. Not least because in science education such a meta-language might contribute to improve writing training and feedback-giving.

Purpose: The aim of this study was to explore students’ perception of teachers’ feedback given on their texts in two genres, and to suggest how writing training and feedback-giving could become more efficient.

Sample: In this study were included 44 degree project students in biology and molecular biology, and 21 supervising teachers at a Swedish university.

Design and methods: The study concerned students’ writing about their degree projects in two genres: scientific writing and popular science writing. The data consisted of documented teacher feedback on the students’ popular science texts. It also included students’ and teachers’ answers to questionnaires about writing and feedback. All data were collected during the spring of 2012. Teachers’ feedback, actual and recalled – by students and teachers, respectively – was analysed and compared using the so-called Canons of rhetoric.

Results: While the teachers recalled the given feedback as mainly positive, most students recalled only negative feedback. According to the teachers, suggested improvements concerned firstly the content, and secondly the structure of the text. In contrast, the students mentioned language style first, followed by content.

Conclusions: The disagreement between students and teachers regarding how and what feedback was given on the students texts confirm the need of improved strategies for writing training and feedback-giving in science education. We suggest that the rhetorical meta-language might play a crucial role in overcoming the difficulties observed in this study. We also discuss how training of writing skills may contribute to students’ understanding of their subject matter.  相似文献
