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

Purpose: This is a report of teacher and student reflections on some of the tensions, reconciliations and feelings they experienced as they worked together to engage in inquiry learning. The study sought to find out how networked ICT use might offer new and different ways for students to engage with, explore and communicate science ideas within inquiry.
Sample: This project developed case studies with 6 science teachers of year 9 and 10 students, with an average age of 13 and 14 years in three New Zealand high schools. Teacher participants in the project had varying levels of understanding and experience with inquiry learning in science. Teacher knowledge and experience with ICT were equally diverse.
Design and Methods: Teachers and researchers developed initially in a joint workshop a shared understanding of inquiry, and how this could be enacted. During implementation, the researchers observed the inquiry projects in the classrooms and then, together with the teachers, reviewed and analysed the data that had been collected.
Results: At the beginning of the project, some of the teachers and students were tentative: inquiry based teaching supported by ICT meant initially that the teachers were hesitant in letting go some of the control they felt they had over students learning, and the students felt insecure in adopting some responsibility for their own learning. Over time a sense of trust and ease developed and this ‘control of learning’ balance moved from what was traditionally accepted, but not without modifications and reservations.
Conclusions: There is no clear pathway to follow in moving towards ICT-supported science inquiry in secondary schools. The experience of the teacher, the funds of knowledge the students bring to the classroom, the level of technological availability in the school and the ability of the students are all variables which determine the nature of the experience. 相似文献
Purpose: This study examines the relationships between classroom goal structure perception variables (motivating tasks, autonomy support, and mastery evaluation), engagement (behavioral, emotional, cognitive, and agentic engagement), self-efficacy, and science achievement.
Sample: The study participants included 744 seventh-grade students from 9 public schools in two districts of Gaziantep in Turkey.
Design and methods: Data were collected through the administration of four instruments: Survey of Classroom Goals Structures, Engagement Questionnaire, Motivated Strategies for Learning Questionnaire, and Science Achievement Test. The obtained data were subjected to path analysis to test the proposed model.
Results: Students’ perceptions of classroom goal structures (i.e. motivating tasks, autonomy support, and mastery evaluation) were found to be significant predictors of their self-efficacy. Autonomy support was observed to be positively linked to all aspects of engagement, while motivating tasks were found to be related only to cognitive engagement. In addition, mastery evaluation was shown to be positively linked to engagement variables, except for cognitive engagement, and self-efficacy and engagement (i.e. behavioral, emotional, and cognitive engagement) were observed to be significant predictors of science achievement. Finally, results revealed reciprocal relations among engagement variables, except for agentic engagement.
Conclusions: Students who perceive mastery goal structures tend to show higher levels of engagement and self-efficacy in science classes. The study found that students who have high self-efficacy and who are behaviorally, emotionally, and cognitively engaged are more successful in science classes. Accordingly, it is recommended that science teachers utilize inquiry-based and hands-on science activities in science classes and focus on the personal improvement of the students. Furthermore, it is also recommended that they provide students with opportunities to make their own choices and decisions and to control their own actions in science classes. 相似文献
Purpose: The focus of this research is development and testing of a new classroom observation protocol specifically designed for SSI-based instructional contexts.
Design and methods: Development of this SSI-Observation Protocol (SSI-OP) took place in four distinct phases: review of existing protocols and SSI-based instruction frameworks, writing and revision of protocol items, initial testing of the draft protocol, and soliciting feedback from SSI experts.
Sample: Following the four stages of SSI-OP development, we progressed to a series of field tests. The field tests were conducted with three different samples. The first sample was an experienced (10 + years) high school biology teacher and one of her honors biology classes. The second sample consisted of seven Turkish Pre-service Science Teachers (PST) participating in a science methods course. The third sample included two Thai PST from a field experience course embedded within a teacher education program.
Results: The final version of the protocol addressed five dimensions of SSI-based instructional activities: focus of instruction, teaching moves, role of teacher, role of students, and classroom environment.
Conclusions: The SSI-OP could be used in a variety of ways for research including documentation of current practices, impacts of professional development and/or curricula on teaching practices, and changes in teaching over time. We offer the SSI-OP as a new tool with the potential to contribute to science teacher education and research that may advance the teaching and learning of science through SSI. 相似文献
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
Purpose: It is designed to help students deconstruct the level of organisation of each tier of a genetic diagram, as the symbols used in such diagrams (i.e. lines and letters) can be too abstract to serve as hints for students to identify the level of organisation.
Design and method: The method employs hybrid dynamic visualisation, which combines static (e.g. a genetic diagram) and dynamic visualisations (e.g. meiotic cell division, fertilisation). The method also addresses the learning problem wherein students isolate the conceptual components of the processes of meiotic cell division and fertilisation from the procedural components of genetic diagrams. The new pedagogy was trialled in a voluntary enrichment course with 22 Secondary Six (or 12th grade) students.
Results: The results of conceptual assessments and individual interviews show that the participating students, in general, provided more explanations at the molecular level, although there is considerable room for improvement in making a smooth macro–micro transition. Students also had a better grasp of the symbolic representation and mathematical concepts of genetics. In addition, their responses in individual interviews revealed that they shared a restricted understanding of the term ‘recessiveness’.
Conclusion: Possible scaffolds for revisiting the concept of recessiveness in regular teaching are suggested. 相似文献
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
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
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
A consecutive approach to training implies that a student spends a part of the training period in an educational institution and a part in a practical situation (i.e. on teaching practice). However, the consecutive system presents considerable problems in respect both of organisation and of the psychology of learning. Organisationally, there is the question of sequence to be faced, if the elements of theory and practice are to be brought together.
On the basis of a study of the literature of other forms of professional training, the following suggestions are made:
-
students’ activities in the school must re‐inforce their learning and be integrated with their work in the training institution;
-
their educational studies must support the acquisition of the competences needed by the teacher at the outset of his/her professional career;
-
attention must be paid to the learning needs and the potential of each student.
The article describes how a teacher training programme may follow these guidelines, leading to a ‘concurrent’ set of cycles bringing together elements of theory, practice and reflection upon practice, and in which a student may alternate between the academic institution and school practice.
After giving an overview of possible models of training the author focuses upon a specific example and provides a model of the institution‐practice link. What is important is that the learning style of the student be taken into account. Each student selects from four alternative programmes, namely: instructional variants, reflection variants, selfstudy variants, and practice variants. The contents of these four programmes are explained, and the learning outcomes of students from these differentiated programmes compared with those of students from undifferentiated, ‘normal’ programs. In summary, it is claimed that in the research project described there are positive indications for a theory‐practice link which gives students a choice of approaches and a better integration of their learning into the practical classroom situation. 相似文献
Design/Methodology/Approach: This study was conducted in Ireland using a pre-test, post-test experimental design. All students were instructed on how to complete two skills using either a traditional or blended methodology. They were subsequently assessed to determine their ability to perform the practical skills.
Findings: The findings stressed the suitability of blended learning not only when it was found that there was no significant difference between method of teaching and skill acquisition but also when it was revealed that student demographics had no major influence on skill acquisition.
Practical Implications: It can be concluded that blended learning can be used effectively for the instruction of a diverse range of practical skills in agricultural college and benefit in the successful knowledge transfer to a growing and diverse student population with more emphasis placed on the students taking charge of their own learning environment.
Originality/Value: The article demonstrates the value of blended learning as a successful medium for practical skill attainment within the agricultural college environment.

This individualized learning programme is defined and illustrated. The components of the role of mentor are likewise defined and illustrated. Then the implications of being a mentor working with individual students are spelt out as they illuminate the relationships of mentors in academia.
The conclusion is offered that the mentor's commitment to his/her students is an exhibition of his/her fundamental commitment to a philosophical stance in education which surmounts primary loyalty to one's academic faculty.
The final whimsical question is whether or not individualized learning and distance education are compatible or conflicting. 相似文献
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
The responsive social context is increasingly seen by developmental psychologists (Bronfenbrenner, 1979; Wood, 1982) as of fundamental importance for the acquisition of intellectual skills. It is within responsive social contexts that individuals acquire not only specific skills but also generic knowledge about how to learn. It is this generic knowledge that allows individuals a measure of control over, and hence independence in, these social contexts.
Educational policy statements, school prospectuses and, more recently, the Core Curriculum, abound with aims and objectives to do with achieving individual autonomy and independence as a learner. Yet there is growing evidence that in many contemporary classrooms at primary, secondary and tertiary levels, we may be providing precisely the wrong contexts for students to become autonomous and independent learners. Too many classroom learning environments simply do not qualify as responsive social contexts. Individual learners have minimal control over learning interactions and hence are excessively dependent on external control by teachers.
Theoretical explanations for differences between unskilled and skilled performance are being sought increasingly in terms of characteristics of the specific contexts in which performance occurs and less in terms of qualitative differences in global capacities or in thinking processes between individuals (Wood, 1982). For example, differences in complexity of oral language between three‐year‐old children might be explained by differences in the amount and quality of language exchange with caregivers. They might also be explained by differences in caregiver skills in interpreting and responding to needs signalled by an individual child's use of language in a particular context. If we are genuinely concerned about aims of autonomy and independence in learning, then we need to discover and analyse those characteristics of responsive environments which support and promote independent learning. On the basis of existing research it is possible to specify four such characteristics of responsive learning contexts.
Purpose: The study was designed to conduct and evaluate the effectiveness of a repertoire of interventions aimed at enhancing secondary school students’ metacognitive capabilities and their achievements in science.
Sample: A class of 35 Year 9 students participated in the study.
Design and methods: The study involved a pre-post design, conducted by the first author as part of the regular designated science programme in a class taught by him.
In order to enhance the students’ metacognitive capabilities, the first author employed clearly stated focused outcomes, engaging them in collaborative group work, reading scientific texts and using concept mapping techniques during classroom instruction. The data to evaluate the effectiveness of the metacognitive interventions were obtained from pre- and post-test results of two metacognitive questionnaires, the Metacognitive Support Questionnaire (MSpQ) and the Metacognitive Strategies Questionnaire (MStQ), and data from interviews. In addition, pre-test and post-test scores were used from a two-tier multiple-choice test on Light.
Results: The results showed gains in the MSpQ but not in the MStQ. However, the qualitative data from interviews suggested high metacognitive capabilities amongst the high- and average-achieving students at the end of the study. Students gains were also evident from the test scores in the Light test.
Conclusion: Although the quantitative data obtained from the Metacognitive Strategies Questionnaire did not show significant gains in the students’ metacognitive strategies, the qualitative data from interviews suggested positive perceptions of students’ metacognitive strategies amongst the high- and average-achieving students. Data from the Metacognitive Support Questionnaire showed that there were significant gains in the students’ perceptions of their metacognitive support implying that the majority of the students perceived that their learning environment was oriented towards the development of their metacognitive capabilities. The effect of the metacognitive interventions on students’ achievement in the Light test resulted in students displaying the correct declarative knowledge, but quite often they lacked the procedural knowledge by failing to explain their answers correctly. 相似文献
Purpose: The study aims to understand how seventh grade students perceive a collaborative web-based science project in light of Wolff’s design categories. The goal of the project is to develop their technological and collaborative skills, to educate them about technology integration practices, and to provide an optimum collaborative, PBL experience.
Sample: Seventh grade students aged 12–14 (n = 15) were selected from a rural K–12 school in Turkey through purposeful sampling.
Design and methods: The current study applied proactive action research since it focused on utilizing a new way to enhance students’ technological and collaborative skills and to demonstrate technology integration into science coursework. Data were collected qualitatively through interviews, observation forms, forum archives, and website evaluation rubrics.
Results: The results found virtual spaces such as online tutorials, forums, and collaborative and communicative tools to be beneficial for collaborative PBL. The study supported Wolff’s design features for a collaborative PBL environment, applying features appropriate for a rural K–12 school setting and creating a digitally-enriched environment. As the forum could not be used as effectively as expected because of school limitations, more flexible spaces independent of time and space were needed.
Conclusions: This study’s interdisciplinary, collaborative PBL was efficient in enhancing students’ advanced technological and collaborative skills, as well as exposing them to practices for integrating technology into science. The study applied design features for a collaborative PBL environment with certain revisions. 相似文献
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
Purpose: LBD uses the context of design challenges to learn, among other things, science. Previous research shows that this approach to subject integration is quite successful but provides little profit on (scientific) concept learning. For this, a lack of (knowledge of) proper teaching strategies is suggested as an important reason. This study explores these strategies and more specific the interaction with concept learning.
Sample: Six Dutch first-year bachelor’s degree science student teachers, between the ages of 16 and 18, and two science teacher trainers (principal investigators included) were involved.
Design and methods: A mixed methods study was used to study LBD’s teaching practice in depth. Based on a theoretical framework of (concept) learning-related teaching strategies video recordings of a guided LBD challenge were analysed to unravel teacher handling in detail. Complemented by questionnaire and interview data and students’ learning outcomes (pre- and post-exam) the effectiveness of teaching strategies was established and shortcomings were distracted.
Results: Students reached medium overall learning gains where the highest gains were strongly task-related. Teacher handling was dominated by providing feedback and stimulating collaboration and only 13% of all teacher interventions concerned direct explication of underlying science. And especially these explicit teaching strategies were highly appreciated by students to learn about science.
Conclusions: In accordance with insights about knowledge transfer, LBD needs to be enriched with explicit teaching strategies, interludes according to poor-related science content important for cohesive understanding and de- and recontextualisation of concepts for deeper understanding. 相似文献
