古代教学语用学思想探析

古代是教学语用学思想的孕育和形成时期.在这一时期,教学语用学思想的雏形已基本形成,主要包括注重教学话语使用、强调教学话语理解、重视教师理解学生等方面的内涵,并为教学语用学在近代的发展奠定了坚实的基础.     

促进深度学习的教学推理:实践逻辑与策略选择

学生的深度学习是以学生的知识理解与运用为价值取向,以培养学生的高阶思维能力和问题解决能力为目标的一种学习。但知识论证不充足、知识点状分布、绝对真理知识观等表层知识教学已偏离了学习的本质及价值,产生了知识教学阻滞深度学习的困局。教学推理是教师根据已知教学条件及个体情境认知,确定问题并生成教学策略的连续性思维活动。它克服了以往僵化的教学方式,为促进深度学习提供可能逻辑。其中,学科知识逻辑能促进学习触及知识的意义世界,学生经验逻辑能促进学习进入学生的心灵世界,实践自为逻辑能促进学习关联自我的生活世界。最后,促进深度学习的教学推理策略应着力于以"批判与交融"为取向的教学理解,形成以"联结与转化"为纽带的教学逻辑,开展以"假设与证据"为核心的课堂论证教学,创设以"推断与评估"为特质的教学情境。     

A new instrument for measuring pre-service biology teachers' pedagogical content knowledge: The PCK-IBI

Teachers' pedagogical content knowledge (PCK) is highly important for effective design and implementation of school teaching. Thus, the current status, development and efficacy of this knowledge, its relationships with teaching quality parameters, and its impact on students' learning processes and success, require rigorous examination. Thoroughly validated, objective and reliable test instruments that are highly sensitive to changes in variables of proven knowledge-related relevance in teacher education are also required. Previous attempts to design such instruments for assessing science teachers' PCK have largely focused on mathematical content. Therefore, here we present an instrument (the pedagogical content knowledge in biology inventory, PCK-IBI), based on conceptualizations of teachers' professional competence, for assessing secondary school pre-service biology teachers' PCK. In a series of three evaluations and refinements it was tested with samples of N = 274 and N = 432 German pre-service as well as one sample of n = 65 German pre-service and n = 35 German in-service biology teachers. Item analysis, scale analysis and empirically obtained indicators of validity suggest that the final 34-item-version of the PCK-IBI is unidimensional, provides objective test scores and enables reliable and valid registration of pre-service biology teachers' PCK. Thus, hypotheses regarding specific aspects of the model on which the PCK-IBI's construction is based on are empirically supported. The results of our study provide empirical support for the instrument's potential utility.     

What Is Happening with Portable Computers in Schools?

This study was an exploratory of the Landes initiative to supply all pupils and teachers with portable computers and Internet at school. These surveys involved 817 pupils and parents and produced a response rate of 98% for pupils from the first survey at the beginning of the year and 798 pupils at the end of the year. The approach, which consists of identifying any variances in individual perceptions of technology, was tested in an initial In-Tele research programme in which we were involved. The questionnaire-based survey reveals low usage of information technology in terms of teaching, with no difference between the portable and test groups. Moving on from the first level study, characterizing the sites and studying their viewing frequency produces the surprising outcome that the very high number of sites viewed actually conceals a much more pessimistic reality about pedagogical uses.     

Habermas, Carr and the Possibility of a Science of Education

A recent attempt to answer questions on the scientific status of education draws on the thoughts of Jürgen Habermas. There is a tension in Habermas's work because he consigns scientific endeavour to the realm of instrumental action, while attempting to base his theory of communication on scientific results. This suggests that either his theory is wrong and science is not merely instrumental, or that his recent proposals mistake manipulation for understanding. This proposition is considered by examining the work of Wilfred Carr, who has taken up the ideas of Habermas. Carr interprets and develops Habermas's theory within an analytical framework, situating it in relation to recent developments in the philosophy of education and philosophy more generally, bringing new light on the relationship between critical theory and education, and overcoming certain limitations of previous scientific characterisations. However, it is argued here that Habermas's idea of science is too abstract to provide a sufficiently complex grounding for substantive, socially liberating, educational practise.

Learning to teach: pedagogical content knowledge in adventure-based learning

Background: Many alternative curricular models exist in physical education to better meet the needs of students than the multi-activity team sports curriculum that dominates in the USA. These alternative curricular models typically require different content knowledge (CK) and pedagogical CK (PCK) to implement successfully. One of the complexities of learning to teach these models for pre-service teachers (PTs) is understanding the different CK and PCK required which is compounded by their personal lack of experience of the model.

Purpose: The purpose of this study was to explore the PCK enacted by PTs learning to teach an alternative curricular model (adventure-based learning [ABL]) in urban middle schools.

Research design: Qualitative methods were used to explore how the PTs demonstrated their PCK while teaching an ABL unit to urban middle school students. The study took place at a major university and in three middle schools in a large urban school district in Midwestern USA.

Participants: Thirteen PTs enrolled in the secondary methods course and associated internship agreed to participate in this study. The PTs (five males and eight females) ranged in age from 21 to 26 years and all self-identified as white.

Data collection and data analysis: Three methods of data collection were employed in this study: interviews, daily reflections called critical friends, and stimulated recall reflection of teaching an ABL lesson. Data were analyzed using constant comparison. Trustworthiness was established through triangulation of the data using multiple data sources, peer debriefing, member checking, and negative case analysis.

Findings: Four themes represented the PTs' demonstration of PCK when learning to teach ABL in urban middle schools. The themes were (a) trusting the sequence, (b) knowing your students, (c) facilitate don't dictate, and (d) processing the experience. The findings provide further insight into the demonstration of PTs' PCK in secondary physical education, and specifically relative to teaching ABL in urban middle schools. To better equip PTs to be able to teach using these models, we recommend the following: (a) they have the opportunity to ‘live the curriculum' in their PETE programme, (b) developing the PTs' specific CK and student-centered pedagogical knowledge for specific alternative curricular models is imperative in developing the PCK for such model, (c) developing PTs' knowledge of students relative to the complexities of learning to teach each specific model, (d) observing an expert teach the model to K-12 students, and (e) recognizing that learning to teach these models is a developmental process and providing the PTs with an emotionally safe and caring space to explore teaching such models is crucial.     

The influence of content knowledge on teaching and learning in Traditional and Sport Education contexts: an exploratory study

Background: Our understanding of the role in which content knowledge (CK) can strengthen instructional models and how that knowledge matters for professional development is limited. It is contended that mere use of an instructional model is insufficient to impact psychomotor learning in meaningful ways.

Purpose: This study was conducted to investigate how a teacher's enacted pedagogical content knowledge (PCK) differed as a function of CK and Sport Education (SE), and to investigate the relative contribution of CK and Sport Education on student learning in terms of swimming performance.

Methods: Four intact classes comprising 88 secondary school students (age: 16–17 years) were randomly assigned to a Traditional, an Sport Education, a Traditional-CK, and a SE-CK group. All classes were taught by the same teacher during a 10-day unit of instruction in the front crawl.

Results: Results showed that the teacher's PCK differed as a function of improved CK. For verbal representations, the amount of cues in the Traditional-CK and SE-CK groups increased about sixfold compared to the Traditional and the SE group. For visual representations, more partially incorrect demonstrations were observed than correct demonstrations in the Traditional and the SE group. More mature and developmentally appropriate tasks were observed in the Traditional-CK and the SE-CK group compared to the Traditional and the SE group. Students in the Traditional-CK and SE-CK groups demonstrated a significant reduction of their amount of strokes on 50?m compared to the Traditional group. A significant interaction effect revealed a larger increase in swimming performance in the CK groups compared to the Traditional and the SE group. Finally, students in the SE group swam significantly more laps than their counterparts in the other groups.

Discussion and conclusion: These results show the impact on student learning when CK was added to both Traditional and Sport Education conditions and contribute to the literature for pre- and in-service teachers. The Sport Education model did not contribute to students’ swimming performance. Students in the Traditional and the SE group did not get the same quality of instruction as students in the Traditional-CK and SE-CK conditions. The latter groups received content that was presented differently both as a presentation and in terms of the actual task. In short, students in the Traditional and Sport Education conditions experienced the content differently than those in the Traditional-CK and SE-CK conditions. These instructional differences resulted in students in the Traditional-CK and SE-CK conditions improving their swimming performances in terms of technical efficiency and in terms of 50?m times.
