Inquiry-Based Science: Turning Teachable Moments into Learnable Moments

This study examines how an inquiry-based approach to teaching and learning creates teachable moments that can foster conceptual understanding in students, and how teachers capitalize upon these moments. Six elementary school teachers were videotaped as they implemented an integrated inquiry-based science and literacy curriculum in their classrooms. In this curriculum, science inquiry implies that students search for evidence in order to make and revise explanations based on the evidence found and through critical and logical thinking. Furthermore, the curriculum material is designed to address science key concepts multiple times through multiple modalities (do it, say it, read it, write it). Two types of teachable moments were identified: planned and spontaneous. Results suggest that the consolidation phases of inquiry, when students reinforce new knowledge and connect their empirical findings to theory, can be considered as planned teachable moments. These are phases of inquiry during which the teacher should expect, and be prepared for, student utterances that create opportunities to further student learning. Spontaneous teachable moments are instances when the teacher must choose to either follow the pace of the curriculum or adapt to the students’ need. One implication of the study is that more teacher support is required in terms of how to plan for and effectively utilize the consolidation phases of inquiry.

Teachable Moments,Learnable Moments: Medical Rounds as a Paradigm for Education

The medical profession has for almost a century employed various types of “Rounds” as pedagogical tools to engage physicians, physicians‐in‐training, and their health care teams in the clinical diagnosis and treatment of patients. More recently, this validated paradigm of medical rounds (MR) has been extended to the field of education, where it is being used as an effective strategy for administrators to better understand their own domain. There are four distinct types of MR which can be further analyzed to find commonalities and parallels with the domain of education. The four types of MR are (1) Morning Rounds, (2) Chart Rounds, (3) Grand Rounds, and (4) Ongoing Collaborations—each have unique pedagogical characteristics and serve different functions. They are, however, unified by common threads of dynamic and interpersonal interactions wherein teacher (physician) and learner (physician‐in‐training) share learning and fluidly exchange roles in the pedagogy. MR models supplant the now outmoded theory of the “empty vessel” and corroborate the concept of the teaching brain. A formal analysis of MR underscores its ongoing utility in education both for its pedagogical innovations and for the Interactive and inherently human attributes that are required between teacher and learner for its efficacy.

<正>我们往往用记忆来衡量生活。最快乐或最震惊的、最激动或最紧张的、最有趣或最艰苦的,从一个到下一个里程碑的奋斗,在我们脑海中最为突出。这些是我们不遗余力地去做、去计划、去效力、去付出的事情。广告鼓励我们去尝试用尽可能多的体验填满生活。当重要的时刻到来时,我们用智能手机拍照,上传到社交媒体甚至日志,或者告诉我们的朋友和孩子。这些事情我们能记住很多年,但是在这些事情间隙里的其他事情都被     

Numinous Moments in the Classroom

Abstract

Service learning combines community service with academic learning. Students learn and develop critical thinking through active participation in organized service experiences. The purpose of this study was to describe the growth of 94 nursing students' critical thinking through service-learning experiences. Results revealed two major themes: development of both professional and community perspectives. Outcomes of the study provide a framework for developing service-learning experiences across the curriculum.

意大利锡耶纳的中古时光

锡耶纳似乎是每个意大利鉴赏家所钟爱的城市。该城不仅有众多可赏之处,其本身就是一道风景。手捧一杯冰激凌,加入晚间散步的人流中,最后来到锡耶纳壮丽的、由红砖砌成的主广场。倚柱而立,落日的余辉抚弄着石头和天空,两者的色彩随之变幻不定。黄昏时分,天空幻化为宝蓝色的穹顶,恰如高高擎着它的中世纪塔楼一般夺目辉煌,初涉诗坛者玩味着这一奇妙的时刻。
