在过去的十年中,对数学教师专业知识(包括例如数学内容知识,数学教学内容知识和一般教学知识)的评估研究已经变得突出;然而,基于视频的评估方法的发展是一个较新的主题。本文遵循的呼吁,更多的情境和绩效相关的方法来评估教师的能力。我们讨论的理论和方法的挑战,连接到这些工具的发展,并在后续研究的国际“教师教育和发展研究数学(TEDS-M)”,称为TEDS-FU的工具开发。借鉴认知心理学的新手-专家框架,分析数学教师专业能力的结构与发展。最近的概念,教师注意到课堂情况和学生的活动被纳入这个基于视频的评价工具,这是本文详细描述,通过评估感知,解释和决策技能。可靠性和有效性问题仍然是这种评估的一个问题,为此提出了解决办法。总体而言,本文表明,一个更全面的评价教师的能力,包括认知情感和情境方面是可能的,并已实现。
Research on the evaluation of the professional knowledge of mathematics teachers (comprising for example mathematical content knowledge, mathematics pedagogical content knowledge and general pedagogical knowledge) has become prominent in the last decade; however, the development of video-based assessment approaches is a more recent topic. This paper follows the call for more situated and performance-related ways to assess teacher competence. We discuss the theoretical and methodological challenges connected to the development of such instruments and exemplify these by an instrument developed within the follow-up study of the international “Teacher Education and Development Study in Mathematics (TEDS-M)”, called TEDS-FU. Drawing on the novice-expert framework from cognitive psychology allows analysing the structure and development of mathematics teachers’ professional competence. More recent concepts on teacher noticing of classroom situations and students’ activities are incorporated into this video-based evaluation instrument, which is described in detail in this paper, by assessing perceptual, interpretative and decision-making skills. Reliability and validity concerns remain an issue of such assessments for which solutions are proposed. Overall, the paper shows that a more comprehensive evaluation of teachers’ competence comprising cognitive-affective and situated facets is possible and has been achieved.
