学生——交际语言教学法中最重要角色(英文)

教师和学生是在交际语言教学法中的两个重要角色。在传统教育理念中,学生的角色没有引起老师足够重视。该文再次强调交际语言教学法中的教师和学生角色,让教师们能更清楚理解学生在交际教学法中充当更主要角色。为了培养学生的英语交际能力,教师应该重新思考学生角色并鼓励学生在课堂发挥更积极的作用。     

听讲式接受学习过程中存在的一些问题--一种来自认知负荷的观点

听讲式接受学习仍是传统课堂教学的主要模式，但它存在着很多固有的缺陷。从认知负荷的观点来看，在这种模式下，教师很难有效地解决学生认知负荷的个别差异，大部分学生不能满负荷学习；学生也很难有效地使用认知资源、认知容量、认知策略和信息外存。剖析这些影响学习荻取知识和技能的因素，可给课堂教学改革以启迪。     

Communicative-based curriculum innovations between theory and practice: implications for EFL curriculum development and student cognitive and affective change

This qualitative study examines the influence of teacher conceptualisations of communicative language teaching on their actual classroom practice and student cognitive and affective change. The qualitative paradigm underpinned this research at the levels of ontology (multiple teacher realities), epistemology (interaction with, rather than detachment from, the respondents), and methodology through using an idiographic strategy (qualitative case study), instruments (qualitative interviews, participant observation and questionnaires), and data analysis technique (explanation-building). The results indicated that teachers who understood CLT and managed to materialise its principles into action significantly improved student language learning (cognitive change) and motivation (affective change). Moreover, traditional, structural and didactic teaching as well as communicative knowledge that was not translated into practice had almost a typical negative impact on student learning and motivation. Recommendations for curriculum development, teacher development, teacher training and future research are made.     

Interdisciplinary Perspectives Inspiring a New Generation of Cognitive Load Research

This special issue consists of six theoretical papers and an introduction. Each paper describes a current advance to the applications and focus of cognitive load theory (CLT). Four of the papers use an interdisciplinary approach outside of educational psychology by combining CLT with elements of evolutionary biology, mirror neuron research, cognitive brain science, and the philosophy of science. The remaining two papers use an intradisciplinary approach within educational psychology by applying CLT to self-regulation and heuristic learning. This paper introduces CLT, overviews each contribution, and summarizes the main themes.     

Example-Based Learning in Heuristic Domains: A Cognitive Load Theory Account

One classical instructional effect of cognitive load theory (CLT) is the worked-example effect. Although the vast majority of studies have focused on well-structured and algorithmic sub-domains of mathematics or physics, more recent studies have also analyzed learning with examples from complex domains in which only heuristic solution strategies can be taught (e.g., troubleshooting, mathematical proving). Is learning by such examples also effective, and do the same instructional design principles apply? We discuss the main findings of an own research program and of related studies that addressed such questions. We found that CLT’s basic design principles also hold true for heuristic domains: Reduce extraneous load by employing examples, maximize germane load by fostering self-explanations, prevent cognitive overload by pretraining in the case of difficult learning materials, and by focusing attention on the most relevant aspects. Other typical CLT assumptions (e.g., better provide information for novice learners) were not confirmed in its generality. The present findings extend the applicability of CLT but also identify some potentially too simplistic assumptions.     

Cognitive Load Theory and Complex Learning: Recent Developments and Future Directions

Traditionally, Cognitive Load Theory (CLT) has focused on instructional methods to decrease extraneous cognitive load so that available cognitive resources can be fully devoted to learning. This article strengthens the cognitive base of CLT by linking cognitive processes to the processes used by biological evolution. The article discusses recent developments in CLT related to the current view in instructional design that real-life tasks should be the driving force for complex learning. First, the complexity, or intrinsic cognitive load, of such tasks is often high so that new methods are needed to manage cognitive load. Second, complex learning is a lengthy process requiring learners motivational states and levels of expertise development to be taken into account. Third, this perspective requires more advanced methods to measure expertise and cognitive load so that instruction can be flexibly adapted to individual learners needs. Experimental studies are reviewed to illustrate these recent developments. Guidelines for future research are provided.     

Modeling teachers’ reactions to unexpectedness

BackgroundEven experienced teachers make inconsistent classroom decisions in unexpected situations. From the cognitive load theory perspective, the effective handling of the novel, unexpected events by teachers depends on the cognitive load of the task, the teaching context in which the unexpectedness appears, and the available cognitive capacity.AimsTeachers’ reactions to unexpected mathematical events, in particular the unexpectedness of the arithmetic calculation, was modeled, investigated experimentally, and explained within the theoretical framework of cognitive load theory.Sample64 mathematics teacher trainees took part in the experiment.MethodsIn a dual-task arrangement, participants verified alternative answers to simple mathematical questions while memorizing task-irrelevant information. The answers represented low (schematic good responses), and high (unexpected good responses) processing load conditions, and control condition (incorrect responses). The memory load was low or high representing levels of extraneous load. The participants’ cognitive capacity was estimated by a complex working memory span task.ResultsThe verification of unexpected but correct answers was slow and more error-prone as compared with the processing speed and accuracy of schematic answers, presumably due to elevated processing (intrinsic) load. The increase in memory load resulted in slower and more inaccurate verifications. However, working memory capacity was found to mediate the extraneous load effect.ConclusionsThe results stress the importance of well-organized schemas for effective reactions to unexpected classroom events. Furthermore, it highlights the importance of accurately understanding and being aware of the impact of cognitive load on teachers to improve teaching practice.     

The Scientific Value of Cognitive Load Theory: A Research Agenda Based on the Structuralist View of Theories

In this paper, two methodological perspectives are used to elaborate on the value of cognitive load theory (CLT) as a scientific theory. According to the more traditional critical rationalism of Karl Popper, CLT cannot be considered a scientific theory because some of its fundamental assumptions cannot be tested empirically and are thus not falsifiable. According to the structuralist view of theories introduced by Joseph D. Sneed, a theory may be considered scientific even if it comprises nontestable fundamental assumptions. Rather, the scientific value of a theory results from the holistic empirical content of the overall theory net built around fundamental assumptions and from the successful applications of this theory net to explain and predict empirical findings. This latter view is helpful to explicate some implicit methodological assumptions of CLT research and to avoid the potential circularity of CLT’s fundamental assumptions. Additionally, the structuralist view of theories can be directly used to derive a research agenda for the future development of CLT.     

Pedagogical Content Knowledge: How do student teachers identify and describe the causes of their pupils' learning difficulties?

This study examines the pedagogical content knowledge of student teachers of biology during their teaching practice in school. The research focuses on the assessment of the teachers' ability to identify their pupils' learning difficulties and characterise their presumed sources. Diaries, kept by 40 student teachers in the course of the two stages of their teaching practice (comprising observation of their mentors in action and their own teaching experience), provided the data for a qualitative and quantitative analysis of the findings. A difference between the two stages was found only with regard to the identification of difficulties: the student teachers identified learning difficulties in most of the lessons they observed, but only in half of the lessons they taught. Their characterisation of the sources of the pupils' difficulties and their recurrence were similar during both stages. The sources of the difficulties were defined according to four categories: the pupil's cognitive and affective characteristics, the type of content, the teacher's methods, and factors inherent in the lesson. The characteristics of the pupil were considered the most frequent source of the difficulties. The study points to the need to increase the teacher educators' awareness of the important role of didactic processes, aimed at exposing the student teachers to their pupils' learning difficulties and help them deal with them effectively.

Taming a beast of burden – On some issues with the conceptualisation and operationalisation of cognitive load

Research on cognitive load theory (CLT) has not yet provided facet-specific measures of cognitive load. The lack of valid methods to measure intrinsic, extraneous and germane cognitive load makes it difficult to empirically test theoretical explanations of effects caused by manipulations of instructional designs. This situation also imposes challenges to testing CLT as a theory. This paper critically reflects the conceptualisation of CLT's core concept and the implications for its operationalisation. In order to address some of the challenges we propose a complexity framework that allows the derivation of a priori estimates of mental load that go beyond CLT's notion of element interactivity. In a study we test hypotheses with regard to effects of the variation of sources for intrinsic cognitive load (increase of complexity within tasks) and the variation of sources for extraneous cognitive load (reduction of extraneous cognitive load between tasks) in three ability groups. Complexity-based estimates prove superior to element interactivity-based estimates of mental load in the prediction of performance outcomes. Results also indicate that individual differences in information-processing capacity determine to what extent complexity is reflected as cognitive load. In this respect the proposed framework extends the focus of CLT beyond the discussion of the role of prior knowledge and acquired levels of expertise.     

Does school context moderate longitudinal relations between teacher-reported self-efficacy and value for student engagement and teacher-student relationships from early until midcareer?

Teachers’ self-efficacy and value represent two central components of their motivation. However, there is a scarcity of knowledge regarding the relevance of value for teaching quality and student outcomes, as well as the extent to which interrelations depend on contextual resources and demands. Engaging students in their learning is an essential aspect of teachers’ work which should promote warm and positive relationships between them and their students. Not only teachers’ self-efficacy for student engagement, but also the value they attach to being able to engage students, should be important for teacher-student relationship quality. Using longitudinal structural equation models, we analyzed relations between self-efficacy and value for student engagement, reported teacher-student relationships, and the potential moderating roles of perceived excessive work demands and the resource of school belonging. Data from 395 Australian teachers in primary and secondary schools encompassed 3 timepoints from the end of teacher education, during teachers’ early career (average 3 years teaching), and midcareer (average 10 years teaching). Informed by social cognitive, expectancy-value and job demands-resources theories, key findings revealed that teachers’ reported relationships with their students at midcareer were predicted only at low levels of perceived excessive demands, by early career self-efficacy and early career value in interaction with self-efficacy. At midcareer, value associated with teacher-reported relationships with students only at low levels of excessive demands, and school belonging. Conversely, perceived teacher-student relationship in early career predicted teachers’ value for student engagement at midcareer. Implications for theory, teacher education and teachers’ professional practice are discussed.     

Active teaching to manage course difficulty and learning motivation

Given the recent reported common occurrence of mediocre or substandard academic performance by students in colleges and universities, it has become essential to identify pedagogical factors that might lessen or reverse this trend. Kolb’s experiential learning, Pintrich’s student learning motivation, and cognitive load theories were used as a framework to assess active teaching moderation of the effects of course difficulty on course performance and learning motivation. Hierarchical ordinary least squares (OLS) regression was used to analyse the data. Research subjects were recruited from a medium-sized historically Black college and university (HBCU) students enrolled in STEM (science, technology, engineering, and mathematics) and Business (i.e. management, economics, or accounting) classes. Active teaching was a positive predictor of course grade and learning motivation. Course difficulty was a negative predictor of course grade. Interaction analysis revealed that increases in active teaching reduced (i.e. moderated) the negative relationship between course difficulty on both course grade and learning motivation. Overall, the findings suggest that student learning outcomes are certainly a function of pedagogy (e.g. active teaching), psychological/affective (e.g. learning motivation), and learning content complexity. Active teaching environments should (1) address both cognitive load and emotional responses attributed to difficult coursework, and (2) provide efficacy building opportunities during instructional delivery.     

Effects of different video- or text-based reflection stimuli on pre-service teachers’ emotions,immersion, cognitive load and knowledge-based reasoning

To reflect on ones own or other teachers teaching practices as well as on different reflection stimuli (e.g. videos or texts) can evoke different emotions and entail varying degrees of cognitive load and knowledge-based reasoning for pre-service teachers. Participants in this study were distributed to four groups (“memory”; "video+memory”; “video other”, and “text other”) and reflected online on classroom management facets. Pre-service teachers in the “video+memory” group reported significantly more immersion and enjoyment while reflecting than the other three groups. All groups showed a moderate level of germane load and there were no differences between the groups. Participants in the video+memory and memory group showed higher levels of knowledge-based reasoning than those who reflected on other teachers’ classroom practice. Enjoyment was a significant positive predictor of both immersion and germane load, whereas boredom was a negative predictor. Implications for future research and reflection processes during teacher education are discussed.

Key experiences in student teachers’ development

This study focuses on the question of why student teachers stay in teaching even after a profound ‘practice shock,’ i.e., a shock that in itself seems to characterize the complex and emotionally challenging first year of student teaching. Using a line drawing technique, the study investigates student teachers’ views of their first year of teaching by examining how they picture their development, their key experiences during that development, and the ways in which they coped with these experiences. The results suggest that most student teachers perceive their own development not as a steadily ascending line as is often suggested by research on the development of teachers’ professional identity. Instead, we now surmise that most student teachers view their development as a path with highs and lows that include transformative moments or periods. This relates to the idea of transformative learning and to theories on identity development that suggest people need a crisis for identity development to occur. During such a crisis, we saw that student teachers explicitly reconsidered their connections to teaching and that this reconsideration led to a regained motivation for teaching. It appeared that supervisors or mentor teachers played a significant role in first‐year (student) teachers’ regaining motivation for teaching.     

Standards-based performance assessment for the evaluation of student teachers: a consequential validity study

The instrument Samples of Teaching Performance (STP) was developed to assess student teachers' capacity to plan, deliver and evaluate a unit of instruction. The current study reports consequential validity data collected from supervisors (n?=?20) and student teachers (n?=?62) from three elementary and five secondary teacher preparation programs in Chile that participated in the field-testing of the STP. Student teachers described how this assessment had honed their sense of professionalism and promoted learning of the skills assessed. Supervisors reported enlarging the topics discussed with student teachers and making some changes to the supervisory process. These findings are complemented by an analysis of the STP scores obtained by 24 student teachers, which showed better development of instructional skills when compared to pedagogical reasoning and reflection. These results raise questions about the structure of student teaching to support the implementation of standards-based assessments that entail tasks at different levels of cognitive complexity.     

Prospective teachers’ teaching experience: teacher learning through the use of video

Background: Future teachers need to observe, interpret and analyse teaching during the initial teacher education period. The use of videoed teaching and learning in teacher education promotes reflection, and analysing videos of teaching is helpful in learning effective classroom practices that prospective teachers mostly do not have the chance to observe during fieldwork experiences. The analysis of videos of teaching can be seen as a way to enhance the development of prospective teachers’ professional vision, which, in turn, improves instruction. Purpose: The purpose of this study was to examine prospective teachers’ reflections on video examples depicting their own teaching experiences. It aimed to create a professional development environment to facilitate the prospective teachers’ reflection on their own videos and those of their peers to improve their professional vision. Sample: This study was conducted with over 200 (in 31 groups) third-year prospective mathematics teachers in a university in Western Turkey. The student teachers, receiving training to teach first- to fourth-grade elementary school pupils, were taking a teaching methods course. Design and methods: In the first week of the semester, the student teachers, working in groups, were assigned mathematics topics to teach the elementary school pupils. During the semester, each group prepared by trying out their activities in front of other student teachers in other groups. At the end of the semester, one student teacher from each group presented a short lesson related to their mathematical topic to the elementary school pupils. This lesson was videotaped, then later it was watched and discussed by the student teachers. Of the student teachers who undertook the teaching in the videos, 22 volunteers agreed to be interviewed. All groups of student teachers provided written reflections on their experience. Selected videos of the class discussions about the videos of teaching were also used for triangulation. The data were analysed to identify the issues the prospective teachers reflected upon. A content analysis technique was employed. Results: The data indicated that the prospective teachers were able to reflect on several issues related to effective teaching, connect their theoretical knowledge to their practice and consider issues related to pupil learning and difficulties. Conclusion: The findings suggested that the use of video, together with discussions between the student teachers, had the potential to create promising learning opportunities for prospective teachers.     

Science teaching based on cognitive load theory: Engaged students,but cognitive deficiencies

To improve science learning under demanding conditions, we designed an out-of-school lesson in compliance with cognitive load theory (CLT). We extracted student clusters based on individual effectiveness, and compared instructional efficiency, mental effort, and persistence of learning. The present study analyses students’ engagement. 50.0% of our sample (n = 250, 5th–8th graders) showed satisfying results, 11.2% were not motivated; 38.8% had difficulties to cope with the learning situation. Presumably, most of them had problems in identifying relevant contents, some were precarious about their capabilities. We suppose that those students may have improved performance with extended active support. We may advance future research on guidance in CLT, and its integration in the field of science education.
