Students' metacognitive skills and perceptions are considered important variables for high-quality learning. In this study, students' perceptions were used to identify histological threshold concepts (integrative, irreversible, transformative, and troublesome) in three health sciences curricula. A specific questionnaire was developed and validated to characterize students' perceptions of histological threshold concepts. A sample of 410 undergraduate students enrolled in the dentistry, medicine, and pharmacy degree programs participated in the study. Concepts assessed in the study were clustered to ten categories (factors) by exploratory and confirmatory factor analysis. Concepts linked to tissue organization and tissue functional states received the highest scores from students in all degree programs, suggesting that the process of learning histology requires the integration of both static concepts related to the constituent elements of tissues and dynamic concepts such as stem cells as a tissue renewal substrate, or the euplasic, proplasic and retroplasic states of tissues. The complexity of integrating static and dynamic concepts may pose a challenging barrier to the comprehension of histology. In addition, several differences were detected among the students in different degree programs. Dentistry students more often perceived morphostructural concepts as threshold concepts, whereas medical students highlighted concepts related to two-dimensional microscopic identification. Lastly, pharmacy students identified concepts related to tissue general activity as critical for the comprehension and learning of histology. The identification of threshold concepts through students' perceptions is potentially useful to improve the teaching and learning process in health sciences curricula. 相似文献

ABSTRACTContext-based learning (CBL), promoting students' scientific text comprehension, and fostering metacognitive skills, plays an important role in science education. Our study involves CBL through comprehension and analysis of adapted scientific articles. We developed a module which integrates metacognitive prompts for guiding students to monitor their understanding and improve their scientific text comprehension. We investigated the effect of these metacognitive prompts on scientific text comprehension as part of CBL in chemistry. About 670 high school chemistry students were randomly divided into three groups exposed to high- and low-intensity CBL. One of the high-intensity groups was also exposed to metacognitive prompts. Research tools included pre- and post-questionnaires aimed at measuring students' conceptual chemistry understanding and metacognitive knowledge in the context of reading strategies, before and after exposure to the CBL. Chemistry understanding was reflected by students' ability to identify the main subject of the adapted article and by explaining concepts both textually and visually. We found that high-intensity CBL combined with metacognitive prompts improved students' chemistry understanding of the adapted scientific articles and the ability to regulate their learning. Our study establishes that reading context-based adapted scientific articles advances students' conceptual chemistry understanding. These gains are strongly amplified by domain-specific metacognitive prompts. 相似文献

There has been extensive investigation into factors affecting digital technology integration in learning and teaching, but the complexity of integration continues to elude understanding. Thus, questions about how digital technologies can be best used to support learning persist. This paper argues that methods designed to address complex systems are needed to understand the interplay between teaching, learning and digital technologies. Starting with a developing system model of teachers' technology integration, this study revises the model to include factors of students' experience using digital technologies and beliefs about learning. The revised model is then used to demonstrate possible effects of student experiences in a technologically integrated group learning task. Analysis draws on data from a large-scale Australian study of technology innovation (N = 7406). Data mining techniques are used to identify patterns of students' technology use and perceptions of group work. Findings inform revision of the model to include factors of students' experience and learning and their effects on teachers' practice. Implications for learning design and students' learning experiences are explored. 相似文献

This study examined Chinese and US middle-school science teachers' perceptions of autonomy support. Previous research has documented the link between teachers' perceptions of autonomy and the use of student-oriented teaching practices for US teachers. But is not clear how the perception of autonomy may differ for teachers from different cultures or more specifically how motivation factors differ across cultures. The survey measured teachers' motivation, perceptions of constraints at work, perceptions of students' motivation, and level of autonomy support for students. Exploratory factor analysis of responses for the combined teacher sample (n?=?201) was carried out for each of the survey assessments. Significance testing for Chinese (n?=?107) and US (n?=?94) teachers revealed significant differences in teachers' motivation and perceptions of constraints at work and no significant differences for perceptions of students' motivation or their level of autonomy support for students. Chinese teachers' perceptions of constraints at work, work motivation, and perceptions of student motivation were found to significantly predict teachers' autonomy support. For the US teachers, teacher motivation was the only significant predictor of teachers' autonomy support. A sub-sample of teachers (n?=?19) was interviewed and results showed that teachers in both countries reported that autonomy was important to their motivation and the quality of science instruction they provided to students. The primary constraints on teaching reported by the US teachers related to materials and laboratory space while the Chinese teachers reported constraints related to the science curriculum and standards. 相似文献

Teachers' instructional practice is pedagogically vulnerable when not anchored within detailed and comprehensive observation and understanding of students' immediate responses during instruction. Professional noticing ability, then, is central to, and integrated within, teachers' ability to provide instruction appropriately adapted to students' immediate needs. This article explicates a model of expert noticing for literacy instruction and relates this model to the characteristics of microadaptive teaching decisions. Characteristics, for example, that distinguish expert from less expert noticing during literacy instruction include detailed hypothesizing, breadth and depth of elaboration, observation of learners' metacognitive behavior, and identification of pivotal events. Teacher noticing ability is generally not related to years of experience, but can be learned through participation in sustained, multilevel professional development with an explicit focus on noticing ability. This complex learning integrates teachers' pedagogical and content knowledge with observation of student behaviors, and supports teachers' learning from practice. 相似文献

Two focusing hypotheses were evaluated. First, do adjunct questions, focusing on science concepts and inserted after computer-animated sequences, selectively alter students' attentional or practice processing and thus produce differential learning effects? Theoretically, such questions selectively focus students' attention and enhance concept learning of focused concepts. Second, do these questions still provide enough metacognitive scaffolding to produce differential learning effects when only the first 8 out of 12 sequences are followed by focusing questions? Eighth-grade students (n = 160) were randomly assigned to a control group (lesson alone) or one of four treatment groups (lesson plus 12 questions focusing either on heat or on temperature, or lesson plus the same first 8 questions on heat or temperature followed by 4 placebo questions). Two significant two-way interactions with widely varying F ratios supported the differential focusing hypotheses (12 questions—more robust interaction, 8—less robust interaction). 相似文献

This article presents reflections and guidance concerning assessment literacy in teacher education. Previous inadequacies in teacher training in educational assessment highlight the need for teachers to be assessment literate. Assessment literacy consists of an individual's understanding of the fundamental assessment concepts and procedures deemed likely to influence educational decisions. Due to the current focus on accountability assessments, it is in teachers' best interest, and also the students', that teachers develop a level of understanding in assessment. Assessment, when used appropriately, is also a powerful tool for learning. What is needed to facilitate assessment literacy in teacher education is more than a brief mention of assessment in a course. A course in assessment with an appropriate text is necessary to bring a more complete understanding of assessment to beginning teachers. 相似文献

The need for renewable and non-fossil fuels is now recognised by nations throughout the world. Consequently, an understanding of alternative energy is needed both in schools and in everyday life-long learning situations. This study developed a two-tier instrument to diagnose students' understanding and alternative conceptions about alternative energy in terms of: sources of alternative energy, greenhouse gas emission, as well as advantages, and disadvantages. Results obtained with Years 10 and 11 students (n?=?491) using the 12-item two-tier instrument (α?=?0.61) showed that students' understanding of alternative energy was low (M?=?7.03; SD?=?3.90). The 23 alternative conceptions about alternative energy sources that could be identified from the instrument are reported. The implications for teaching and learning about alternative energy and suggestions for further development and improvement of the instrument are presented. 相似文献

Establishing a well-organized classroom conducive to learning is a key element of high-quality teaching. However, less is known about the degree to which the classroom management process is affected by the specific students in the classroom. Using two large-scale datasets of German secondary school students, the present two studies examined the effectiveness of teachers' classroom management in mathematics while taking into account students' disruptive behavior in the classroom. When controlling for the average level of disruptions in the classroom, both students' disruptive behavior and teachers' monitoring activity were negatively associated with students' mathematics achievement, whereas no associations occurred for teachers' structure and rule clarity. The results suggest that teachers' monitoring activity needs to take into account students’ disruptive behavior in the classroom, highlighting the complexity of effective classroom management. 相似文献

This study is part of a broader research project. The main aim was to find out pedagogic practices which can improve students' science achievement, namely, in complex cognitive competencies. The study is based on Bernstein's theory. Previous studies have suggested that the explicitness of the criteria of evaluation is related to students' scientific understanding and achievement. One of the many ways in which the evaluation criteria can be made explicit to students is through assessment tests, and their correction and marking. In this study, we analyze the extent to which students understand teachers' evaluation criteria, more specifically, teachers' marking criteria and procedures (i.e., the extent to which they have recognition and realization rules to the assessing context). We also analyze the relation of that understanding with social class, social context of the school, teacher's conceptual demand, teachers' explicitness of criteria, and science achievement. A clear relation between students' acquisition of recognition and realization rules and social class is shown: the higher the social class, the higher that acquisition. A privileged school's social context and the teacher's explicitness of assessing criteria also contribute to students' understanding of teachers' evaluation criteria. This understanding influences science achievement, especially in complex competencies. © 1996 John Wiley & Sons, Inc. 相似文献

Previous research has shown that cognitive processing and achievement strategies are important for motor learning and achievement. Despite this, there are few studies identifying the role of motivational beliefs in the cognitive self-regulation of students' learning in physical education classes. This study reports the results of multivariate analyses of the relationships between thirteen to fourteen-year-old secondary school pupils' (n=343) implicit theories of ability and their self-regulated learning in PE. Self-regulation measures included metacognitive/elaboration strategies, effort regulation and adaptive help seeking. Results revealed consistent relationships between motivational beliefs and pupils' use of self-regulation strategies. The results underscore the educational value of reappraising pupils' implicit theories of ability, making them believe in the modifiability of ability through effort and hard work and learning. The results illustrate the importance of linking pupils' motivational and cognitive characteristics to provide a fuller understanding of their self-regulation of learning in physical education. 相似文献

Recent instructional reforms in science education aim to change the way students engage in learning in the discipline, as they describe that students are to engage with disciplinary core ideas, crosscutting concepts, and the practices of science to make sense of phenomena (NRC, 2012). For such sensemaking to become a reality, there is a need to understand the ways in which students' thinking can be maintained throughout the trajectory of science lessons. Past research in this area tends to foreground either the curriculum or teachers' practices. We propose a more comprehensive view of science instruction, one that requires attention to teachers' practice, the instructional task, and students' engagement. In this study, by examining the implementation of the same lesson across three different classrooms, our analysis of classroom videos and artifacts of students' work revealed how the interaction of teachers' practices, students' intellectual engagement, and a cognitively demanding task together support rigorous instruction. Our analyses shed light on their interaction that shapes opportunities for students' thinking and sensemaking throughout the trajectory of a science lesson. The findings provide implications for ways to promote rigorous opportunities for students' learning in science classrooms. 相似文献

Problems persist with physics learning in relation to students' understanding and use of representations for making sense of physics concepts. Further, students' views of physics learning and their physics learning processes have been predominantly found to reflect a ‘surface’ approach to learning that focuses on mathematical aspects of physics learning that are often passed on via textbooks and lecture-style teaching. This paper reports on a teacher's effort to stimulate students' metacognitive reflection regarding their views of physics learning and their physics learning processes via a pedagogical change that incorporated the use of a representational framework and metaphors. As a consequence of the teacher's pedagogical change, students metacognitively reflected on their views of physics and their learning processes and some reported changes in their views of what it meant to understand physics and how they might learn and understand physics concepts. The findings provide a basis for further explicit teaching of representational frameworks to students in physics education as a potential means of addressing issues with their physics learning. 相似文献

The purpose of this study was to examine the ways in which elementary teachers applied their understanding of conceptual learning and teaching to their instructional practices as they became knowledgeable about conceptual change pedagogy. Teachers' various ways to interpret and utilize students' prior ideas were analyzed in both epistemological and ontological dimensions of learning. A total of 14 in‐service elementary teachers conducted an 8‐week‐long inquiry into students' conceptual learning as a professional development course project. Major data sources included the teachers' reports on their students' prior ideas, lesson plans with justifications, student performance artifacts, video‐recorded teaching episodes, and final reports on their analyses of student learning. The findings demonstrated three epistemologically distinct ways the teachers interpreted and utilized students' prior ideas. These supported Kinchin's epistemological categories of perspectives on teaching including positivist, misconceptions, and systems views. On the basis of Chi's and Thagard's theories of conceptual change, the teachers' ontological understanding of conceptual learning was differentiated in two ways. Some teachers taught a unit to change the ontological nature of student ideas, whereas the others taught a unit within the same ontological categories of student ideas. The findings about teachers' various ways of utilizing students' prior ideas in their instructional practices suggested a number of topics to be addressed in science teacher education such as methods of utilizing students' cognitive resources, strategies for purposeful use of counter‐evidence, and understanding of ontological demands of learning. Future research questions were suggested. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 44: 1292–1317, 2007 相似文献

Cooperative learning may improve students' motivation, understanding of course concepts, and academic performance. This study therefore enhanced a cooperative, group-project learning technique with technology resources to determine whether doing so improved students' deep learning and performance. A sample of 118 engineering students, randomly divided into two groups, participated in this study and provided data through questionnaires issued before and after the experiment. The results, obtained through analyses of variance and structural equation modelling, reveal that technology-enhanced, cooperative, group-project learning improves students' comprehension and academic performance. 相似文献

This study had the goal of investigating the association among elementary students' (N = 276) science and math beliefs and the relationship between those beliefs and teachers' ratings of mathematical and science understanding. Results of structural path analysis indicate that in science, intellectual risk‐taking (IRT; the willingness to share tentative ideas, ask questions, attempting to do, and learn new things) was positively related to teachers' ratings of science understanding, while creative self‐efficacy (CSE) beliefs (i.e., students' confidence in their ability to generate ideas and solutions in science) were indirectly related (working through IRT). Results also indicate that students' scientific certainty beliefs (i.e., the belief that science knowledge is stable, fixed, and represented by correct answers) were negatively related to teachers' ratings of science understanding. With respect to math, results indicate that students' CSE beliefs were positively related to teachers' ratings of math understanding; whereas students' mathematical source beliefs (i.e., believing that math knowledge originates from external sources) were negatively related. © 2012 Wiley Periodicals, Inc.

This paper examines how a team of teachers in a Norwegian upper secondary school responds to, negotiates, and evaluates students' writing in and across different disciplines. The purpose is to identify discourse strategies and professional development as the teachers discuss students' texts, and to explore how the teachers develop a shared understanding of how writing relates to students' learning. The findings show how the teachers' discourse reflects an emerging understanding of how writing is both a subject-specific and interdisciplinary skill conducive to learning, but also how institutional traditions and discipline-specific concerns together allow for and constrain teachers' learning. 相似文献

The present study investigated effects of two hypermedia environments on 95 preservice university teachers' self-regulated learning (SRL) in the context of technological pedagogical content knowledge (TPCK): hypermedia with metacognitive instruction (HYP + META) and without (HYP). The study combined online reflections with self-report measures to assess SRL processes. Results showed that exposure to metacognitive support using the IMPROVE self-questioning method may enhance preservice teachers' ability to reflect on and regulate their learning processes. This, in turn, can develop their TPCK, both as learners (comprehension skills) and as teachers (design skills). Further analysis indicated high correlations within SRL measures (self-reports, online reflections) and between SRL and TPCK tasks. Implications are discussed for teacher training in SRL-integrated TPCK contexts. 相似文献

Many studies have pointed to the limited direct effectiveness of instructional interventions and one explanation of this has drawn attention to the importance of 'instructional metacognitive knowledge'. In this exploratory study, instructional metacognitive knowledge of university freshmen is addressed by means of a survey covering: (a) instruction in general, (b) instruction in two different environments, and (c) specific delivery systems and concrete instructional interventions. While some differences appeared in the answers on different sets of questions, also large similarities were found. The results show students' knowledge about instruction to be mainly affected by their instructional experiences. The students' view is 'reactive' and places instructional agents at the core of the instructional process. The findings provide additional support for the importance of correspondence between learners' and teachers' views on instructional interventions if forms of support for students' learning are to be effective. 相似文献
