📚 Year 9 CAIE Physics: Teacher Teaching Suggestions and Lesson Plan Sharing | 九年级CAIE 物理：教师教学建议与教案分享
Year 9 marks the crucial bridge between lower secondary general science and the more formal, disciplinary study of Physics at IGCSE level. For many students, this is the year when abstract concepts become tangible, equations move from intimidating symbols to powerful tools, and a genuine curiosity about how the universe works begins to take root. This article compiles practical teaching suggestions and ready-to-adapt lesson plan frameworks for CAIE Year 9 Physics teachers, focusing on strategies that build both conceptual understanding and the core skills required for future success.
九年级是初中综合科学向 IGCSE 阶段正式分科物理学习过渡的关键桥梁。对许多学生来说，这一年抽象概念变得具体，公式从令人生畏的符号转变为强大的工具，对宇宙运行规律的好奇心也真正开始萌芽。本文为 CAIE 九年级物理教师汇编了实用的教学建议和可直接调整的教案框架，重点聚焦于既能建立概念理解，又能培养未来成功所需核心技能的教学策略。
1. Overview of Year 9 CAIE Physics Curriculum | 课程概览
The CAIE Year 9 Physics syllabus typically serves as a foundation year for the IGCSE 0625 course. Core topics usually include measurement and units, general physics (length and time, speed, velocity and acceleration, mass, weight and density, forces and motion, energy, work and power, pressure), thermal physics (simple kinetic molecular model of matter, thermal properties and temperature), waves (general wave properties, light and sound), electricity and magnetism (simple phenomena of magnetism, electrical quantities, electric circuits), and atomic physics (radioactivity, the nuclear atom). Teachers must map these topics not only to conceptual outcomes but also to the experimental skills and data-handling competencies expected at this level.
CAIE 九年级物理课程通常作为 IGCSE 0625 科目的基础年。核心主题通常包含测量与单位、普通物理（长度与时间、速率、速度与加速度、质量、重量与密度、力与运动、能量、功与功率、压强）、热物理（简单的物质分子动理论模型、热性质与温度）、波（波的一般特性、光与声）、电学与磁学（磁学简单现象、电量、电路）以及原子物理（放射性、核原子）。教师不仅要将这些主题对应到概念性学习成果，还需对应到该阶段预期的实验技能与数据处理能力。
2. Effective Teaching Strategies | 有效的教学策略
Begin each topic with a concrete demonstration or a relatable phenomenon. For example, when introducing forces, use a suspended mass on a spring to immediately connect the abstract idea of weight with a visible extension. This 'phenomenon-first' approach creates a 'need to know' and anchors learning in experience rather than in definitions alone. Inquiry-based learning, even in a structured form, is highly effective. Pose a question like 'Why does a crumpled paper fall faster than a flat sheet?' and let students design a simple investigation before introducing air resistance and terminal velocity. This builds scientific reasoning and engagement.
每个主题都以具体的演示或贴近生活的现象开始。例如，介绍力的概念时，使用弹簧悬挂重物，立即将抽象的“重量”概念与可见的伸长联系起来。这种“现象先行”的方法创造了“需要知道”的情境，并将学习锚定在体验而非单纯的定义之上。探究式学习，即使是结构化的形式，也非常有效。提出诸如“为什么揉皱的纸比平整的纸下落更快？”的问题，让学生先设计一个简单的调查，再介绍空气阻力和终极速度。这可以培养学生的科学推理能力和参与度。
g speed-time graphs, show the graph, write down the description of motion in words, and express the relationship as v = u + at. This triple representation caters to different learning styles and strengthens mental models. Regular retrieval practice via short, low-stakes quizzes at the start of every lesson keeps prior knowledge accessible and identifies gaps early.
坚持使用双重编码：将口头解释与清晰的图表、图形和方程式并排呈现。例如，在教授速度-时间图时，展示图形、用文字写下运动描述，并用 v = u + at 表达关系。这种三重表示法适应不同的学习风格并强化心智模型。每节课开始时通过简短、低压力的测验进行定期提取练习，可使先前知识保持可调用状态，并及早发现知识漏洞。
3. Common Misconceptions and How to Address Them | 常见误区及应对方法
Misconceptions are not simply 'wrong answers'; they are logical constructs built from everyday experience. In Year 9, one of the most persistent is that 'motion implies a force'. Students often believe that if an object is moving, there must be a force acting on it in the direction of motion. Address this by using frictionless tracks or hovercraft simulations to demonstrate that an object in motion will stay in motion at constant velocity unless a resultant force acts. Directly conflict with the misconception through predict-observe-explain (POE) demonstrations.
误区不仅仅是“错误答案”，它们是从日常经验中建构出的逻辑产物。在九年级，最顽固的误区之一是“运动就意味着有力的作用”。学生通常认为，如果物体在运动，就必定有一个力沿着运动方向作用于它。解决这个问题的方法是使用气垫导轨或气垫船模拟，展示如果没有合力作用，运动的物体将以匀速保持直线运动。通过“预测-观察-解释”（POE）演示，直接与误区产生认知冲突。
Another misconception is confusing temperature with heat. Students might say 'the metal feels colder than the wood, so it has a lower temperature', misunderstanding thermal conductivity and thermal equilibrium. Use an infrared thermometer or temperature sensors to show that both objects at room temperature are actually the same temperature, then discuss the transfer of energy. Similarly, many think that heavier objects always fall faster, reinforcing Aristotle's idea. Use a vacuum pump and a feather-and-coin tube to demonstrate that in the absence of air resistance, all objects accelerate equally.
另一个误区是混淆温度与热量。学生可能会说“金属摸起来比木头冷，所以它的温度更低”，这是对导热性和热平衡的误解。使用红外温度计或温度传感器显示两者在室温下实际温度相同，然后讨论能量的转移。同样，许多人认为重物总是下落得更快，强化了亚里士多德的观念。使用真空泵和羽毛硬币管演示在没有空气阻力的情况下，所有物体以相同的加速度下落。
4. Lesson Plan Structure | 教案结构
A robust Year 9 physics lesson plan follows a predictable rhythm that balances direct instruction, active learning, and reflection. Start with a 5-minute retrieval starter: three quick questions from last lesson, last week, and last month. This activates schema. Then move to a 10-minute 'hook' and new material introduction, using a demonstration or a question. Follow with 20 minutes of main activity, which should be a mixture of guided problem-solving, paired work, or a short practical. End with a 10-minute plenary that includes student summary, self-assessment against learning objectives, and a preview of the next topic. Homework should extend practice, not introduce new content.
一节高质量的九年级物理课遵循一个可预测的节奏，平衡直接教学、主动学习和反思。以五分钟的提取性起始活动开始：三个包含上节课、上周和上月内容的快速问题。这能激活图式。然后进入十分钟的“导入”和新内容介绍，使用一个演示或一个问题。接下来是二十分钟的主要活动，应混合有指导的问题解决、配对合作或简短实验。最后以十分钟的总结结束，包括学生小结、根据学习目标的自我评估以及下一主题的预告。家庭作业应延伸练习，不应引入新内容。
A sample lesson on 'Density' might look like this: Starter – which is heavier, a kilogram of feathers or a kilogram of iron? (address mass vs volume). Hook – predict whether a can of regular soda and a can of diet soda will float or sink in water. Main activity – measure mass and volume of regular and irregular solids, then calculate density. Plenary – explain the soda can results using density, and complete an exit ticket with one calculation. Build in scaffolding by providing partially completed data tables and formula prompts for weaker students, while offering extension questions connecting density to particle spacing for high achievers.
一节关于“密度”的示范课可能如下：起始活动—— 一千克羽毛和一千克铁，哪个更重？（解决质量与体积的问题）。导入—— 预测一罐普通汽水和一罐无糖汽水在水里会浮起还是下沉。主要活动—— 测量规则和不规则固体的质量与体积，然后计算密度。总结—— 用密度解释汽水罐的结果，并完成一张包含一个计算的出门票。通过为程度较弱的的学生提供部分完成的数据表和公式提示来搭建支架，而为程度较高的学生提供将密度与粒子间距联系起来的拓展问题。
5. Integrating Practical Work | 融入实验教学
Practical work in Year 9 should move beyond simple 'recipe following' and towards developing investigative skills. Focus on a few key experiments done well: measuring the acceleration of free fall (using a trapdoor and electromagnet or light gates), investigating factors affecting the period of a pendulum, exploring Ohm's law with a resistor and variable power supply, and measuring the specific heat capacity of a metal block. For each, explicitly teach the skill of identifying independent, dependent, and control variables. Use the SC1-style framework: ask students to write a clear hypothesis, design a fair test, record results in a table with correct headings and units, plot a graph, and write a conclusion that references the graph and evaluates reliability.
九年级的实验教学应从简单的“照着步骤做”转向发展探究技能。聚焦于做好几个关键的实验：测量自由落体加速度（使用挡板电磁铁或光门）、探究影响单摆周期的因素、用电阻和可调电源探究欧姆定律、测量金属块的比热容。每个实验都要明确地教授识别自变量、因变量和控制变量的技能。使用类似 SC1 的框架：要求学生写出清晰的假设，设计一个公平测试，在表格中记录结果（含正确的表头与单位），绘制图形，并写出引用图形并评估可靠性的结论。
Simple equipment can be very powerful. Use smartphone sensors (accelerometer, microphone for sound waveforms, light sensor) to bring data logging into the classroom without expensive lab gear. For instance, measure the acceleration of a lift or a car, or capture a sound wave's amplitude and frequency. Always link the practical back to the theoretical model: after measuring current and voltage, have students model the circuit using the rope loop analogy or the Coulombs in a pipe analogy to make the abstract tangible.
简单的设备也可以非常强大。使用智能手机传感器（加速度计、用于声波波形的麦克风、光传感器）在没有昂贵实验室设备的情况下，将数据记录引入课堂。例如，测量电梯或汽车的加速度，或者捕捉声波的振幅和频率。始终将实验与理论模型联系起来：在测量电流和电压之后，让学生用绳圈类比或管道中库仑电荷的类比来模拟电路，使抽象变得具体。
6. Using Technology and Simulations | 运用科技与模拟
When physical labs are limited, interactive simulations like PhET (University of Colorado Boulder) are indispensable. For example, the 'Forces and Motion: Basics' simulation allows students to apply forces, see resulting motion, and graph velocity and acceleration in real time. The 'Circuit Construction Kit' lets them build circuits safely and visualize electron flow. Use simulations not as a replacement for real practicals but as a complementary tool for pre-lab preparation, post-lab reinforcement, and 'what-if' exploration. Always accompany simulation use with a structured worksheet that asks prediction, observation, and analysis questions, preventing aimless clicking.
当物理实验室条件有限时，像 PhET（科罗拉多大学博尔德分校）这样的交互式模拟是不可或缺的。例如，“力与运动：基础”模拟可以让学生施加力，观察产生的运动，并实时绘制速度和加速度图像。“电路组建套件”使他们能够安全地构建电路并可视化电子流动。使用模拟不是为了取代真实的实验，而是作为实验前准备、实验后强化和“假如”探索的补充工具。使用模拟时，始终要配上一份结构化学习单，其中包含预测、观察和分析问题，防止无目的的点击。
Online quiz platforms like Kahoot, Quizizz, or Socrative provide instant feedback and can be used for formative assessment at any point in the lesson. Create 'mash-up' quizzes that mix conceptual questions with simple calculations. For instance: 'A force of 10 N is applied to a 2 kg mass. What is the acceleration? A. 5 m/s² B. 20 m/s² C. 0.2 m/s²' followed by 'If the mass is doubled and the force stays the same, the acceleration...'. This encourages flexible thinking. Use virtual labs like the 'Falling Bodies' simulation to discuss air resistance and terminal velocity in a visually striking way.
Kahoot、Quizizz 或 Socrative 等在线测验平台能提供即时反馈，可在课堂的任何环节用于形成性评估。创建混合了概念性问题与简单计算的“混搭”测验。例如：“一个 10 N 的力作用于一个 2 kg 的物体。加速度是多少？A. 5 m/s² B. 20 m/s² C. 0.2 m/s²”，紧接着“如果质量加倍而力不变，加速度将……”。这能鼓励灵活的思维。使用诸如“落体”虚拟实验，以视觉冲击力强的方式讨论空气阻力和终极速度。
7. Differentiated Instruction | 差异化教学
ome. For the topic of kinetic energy (E = ½ m v²), provide three tiers of practice: Tier 1 – solve for E given m and v, with all units consistent. Tier 2 – solve for v given E and m, requiring rearrangement and square root. Tier 3 – ic energy, and analyse why so much more energy is needed to stop a car at high speeds. Use 'must, should, could' learning objectives to make progression routes explicit.
九年级班级在数学流利度和抽象推理能力上差异很大。可从任务、资源和成果上进行差异化教学。对于动能主题（E = ½ m v²），提供三个层级的练习：第一级—— 根据 m 和 v 求解 E，所有单位一致。第二级—— 根据 E 和 m 求解 v，需要变形和开平方根。第三级—— 一个开放式探究：设计一个实验来验证速度与动能的关系，并分析为什么在高速下使汽车停下来需要如此巨大的能量。使用“必须、应该、可以”的学习目标，使进阶路径清晰可见。
Support learners with 'toolkits' – a single A4 sheet for a topic containing key formulas, a model worked example, and common pitfalls. For English as an Additional Language (EAL) learners, explicitly teach command words like 'state', 'describe', 'explain', and 'calculate', using Frayer models. Pair strong linguists with strong mathematical thinkers in group work to build both language and reasoning. Stretch high attainers with 'Physics beyond the syllabus' reading, such as Newton's original writings or articles on GPS relativity, fostering deeper curiosity.
以“工具箱”支持学习者——针对一个主题的一张 A4 纸，包含关键公式、一个示范例题和常见陷阱。对于英语作为附加语言（EAL）的学习者，使用 Frayer 模型明确教授诸如“state”、“describe”、“explain”和“calculate”等指令词。在小组活动中，将语言能力强的学生与数学推理能力强的学生配对，以同时发展语言和推理能力。通过“超越大纲的物理”阅读材料，如牛顿的原著或关于 GPS 相对论的文章，来拓展高水平学生的思维，培养更深层次的好奇心。
8. Formative Assessment Techniques | 形成性评估技巧
Effective formative assessment in physics goes beyond marking for correctness. Use 'hinge questions' – carefully designed multiple-choice questions that reveal specific misconceptions. For example, on circuits: 'A bulb is in series with a variable resistor. The resistance is increased. What happens to the bulb? A) gets brighter B) gets dimmer C) stays the same D) goes out'. Distractor A addresses the misconception that more resistance means more 'effort' from the battery. Analyse responses in real time and adapt instruction accordingly. Use mini-whiteboards for whole-class simultaneous response, ensuring every student engages.
物理学科中有效的形成性评估不仅仅是对正确与否进行批改。使用“枢纽问题”——精心设计的多项选择题，能够揭示具体的误区。例如，关于电路：“一个灯泡与一个可变电阻串联。电阻增大，灯泡会怎样？A) 变亮 B) 变暗 C) 不变 D) 熄灭”。干扰项 A 针对“电阻越大，电池提供的‘努力’越多”的误区。实时分析回答并相应调整教学。使用迷你白板进行全班同步作答，确保每个学生都参与。
Introduce 'concept mapping' as a revision and assessment tool. After teaching energy, ask students to create a map linking: energy stores (kinetic, gravitational potential, thermal, chemical, etc.), transfers (mechanical work, electrical work, heating, radiation), and the principle of conservation. Look for correct links and missing links to gauge understanding. Provide written feedback that requires action: instead of 'improve your graph', say 'Redraw your graph using a line of best fit and calculate the gradient. What physical quantity does this gradient represent?' Feedback should move learning forward.
引入“概念图”作为复习和评估工具。在能量教学后，要求学生创建一张图，将能量储存（动能、重力势能、热能、化学能等）、转移途径（机械功、电功、加热、辐射）与守恒原理联系起来。通过正确的连接和缺失的连接来判断理解程度。提供需要采取行动的书面反馈：不要说“改进你的图表”，而应该说“用一条最佳拟合线重新绘制你的图表，计算斜率。这个斜率代表什么物理量？”反馈必须推动学习向前发展。
9. Preparing for Progression to IGCSE | 为衔接IGCSE做准备
Year 9 should consciously build the academic habits required for IGCSE Physics. This includes correct use of scientific vocabulary: 'proportional' vs 'directly proportional', 'precision' vs 'accuracy', 'random error' vs 'systematic error'. Embed these terms in everyday discourse. Teach graph-plotting rigorously: independent variable on x-axis, labeled quantity and unit, sensible scales, points plotted as small crosses, and line of best fit (curve or straight). Insist on working shown for calculations: formula in symbols, substitution, answer with correct units and significant figures (usually 2 or 3 sf at IGCSE).
九年级应有意识地培养 IGCSE 物理所需的学术习惯。这包括科学词汇的正确使用：'proportional'与'directly proportional'、'precision'与'accuracy'、'random error'与'systematic error'。将这些术语嵌入日常交流中。严格教授图表绘制：自变量在 x 轴，标注物理量和单位，合理的标度，点用小叉号表示，以及最佳拟合线（曲线或直线）。强调计算过程的展示：符号公式、代入、答案带正确的单位与有效数字（IGCSE 中通常为 2 或 3 位有效数字）。
Familiarize students with the command words used in CAIE exams. Create a classroom poster with 'Define – give the precise meaning of a word or phrase', 'Describe – state the points of a topic / give characteristics and main features', 'Explain – set out purposes or reasons / make the relationship between things evident', and so on. Start using past-paper style questions, but in a scaffolded manner: provide a model answer framework for the first few attempts. Build exam technique early, not as a cramming activity later.
让学生熟悉 CAIE 考试中使用的指令词。制作一张教室海报，写上“Define——给出单词或短语的确切含义”、“Describe——陈述一个主题的要点 / 给出特征和主要特色”、“Explain——阐明目的或原因 / 使事物之间的关系清晰明了”等等。开始使用考试真题风格的问题，但以支架式方式进行：在最初几次尝试中提供模型答案框架。尽早建立考试技巧，而不是后来作为突击活动。
10. Sample Lesson Plan: Forces and Motion | 教案示例：力与运动
Topic: Balanced and Unbalanced Forces, Resultant Force
Year: 9
Duration: 60 minutes
Learning Objectives: By the end of the lesson, students will be able to: 1) Distinguish between balanced and unbalanced forces. 2) Calculate the resultant force from a simple force diagram. 3) Predict the motion of an object given the resultant force.
Starter (5 min): Show an image of a tug-of-war with no movement. Ask: 'Are forces acting? Why is the rope not moving?' Elicit the idea of balanced forces. Quick paired discussion.
Introduction (10 min): Demonstrate with a dynamics trolley. Push it with a single finger (unbalanced force, it accelerates). Then push with two fingers from opposite sides with equal force (balanced, constant velocity or stationary). Define resultant force. Draw force diagrams on board, using arrows with magnitude labels. Show how to find resultant (add if same direction, subtract if opposite).
Main Activity (20 min): Students work in pairs using a card sort activity. Cards have force diagrams (e.g., 5 N left, 3 N right; or 2 N up, 2 N down, 4 N left). For each, they calculate resultant force and match a 'motion description' card (accelerates to left, stationary, moves at constant speed). Provide a worksheet with graduated difficulty: starting with collinear forces, then perpendicular forces (introduction to equilibrium). Circulate and support.
Plenary (10 min): Mini-whiteboard quiz: Show force diagrams, students write resultant magnitude and direction. Address common error: forgetting direction. Then an exit ticket: 'A car engine provides a driving force of 4000 N and friction is 1500 N. The mass is 1000 kg. Calculate resultant force and acceleration.' Collect to assess next lesson.
Differentiation: Provide pre-drawn diagrams for weaker students; extension for high achievers: 'If the car's driving force abruptly drops to zero, describe the subsequent motion using forces.' Use of vector addition with perpendicular forces for those ready.
课题：平衡力与非平衡力，合力
年级：九年级
时长：60 分钟
学习目标：本节课结束时，学生将能够：1) 区分平衡力与非平衡力。2) 根据简单的力示意图计算合力。3) 根据合力预测物体的运动。
起始活动（5 分钟）：展示一张拔河比赛绳子不动的图片。提问：“有力作用吗？为什么绳子不动？”引出平衡力的概念。快速配对讨论。
导入（10 分钟）：用力学小车进行演示。用单根手指推它（非平衡力，它加速）。然后用两根手指从相反侧以相同的力推（平衡，匀速或静止）。定义合力。在黑板上画力示意图，使用带大小标签的箭头。展示如何计算合力（同向相加，反向相减）。
主要活动（20 分钟）：学生两人一组，使用卡片分类活动。卡片上印有力示意图（例如，5 N 向左，3 N 向右；或 2 N 向上，2 N 向下，4 N 向左）。对于每张卡片，他们计算合力并匹配一张“运动描述”卡片（向左加速、静止、匀速运动）。提供一份难度递增的练习单：从共线力开始，然后到垂直力（引入平衡概念）。巡视并提供支持。
总结（10 分钟）：迷你白板测验：展示力示意图，学生写出合力的大小和方向。纠正常见错误：忘记方向。然后是一张出门票：“一辆汽车的发动机提供 4000 N 的驱动力，摩擦力为 1500 N。质量为 1000 kg。计算合力和加速度。”收集以评估下节课的内容。
差异化：为程度较弱的学生提供预先画好的示意图；为高水平学生拓展：“如果汽车的驱动力突然降为零，请用力的概念描述随后的运动。”对于准备好的学生，引入垂直力的矢量合成。
11. Classroom Management Tips | 课堂管理建议
Physics practicals can easily become chaotic if routines are not established. Implement a '3-2-1-Go' countdown for transitions: 3 – stop talking, eyes on teacher; 2 – put down equipment; 1 – hands free, ready to listen. Teach this explicitly in the first lesson and practice. Assign lab roles within groups: 'Resource Manager' collects and returns apparatus, 'Director' reads instructions, 'Experimenter' handles setup, and 'Recorder' logs data. Rotate roles every practical. This ensures all students are accountable and engaged, and avoids reliance on a single 'active' member.
如果不建立常规，物理实验很容易变得混乱。实施“3-2-1-开始”的倒计时用于过渡：3——停止交谈，眼睛看老师；2——放下器材；1——双手空出，准备听讲。在第一节课中明确教会并练习这一点。在小组内分配实验角色：“材料管理员”领取并归还仪器，“指导员”阅读说明书，“实验员”负责搭建，“记录员”记录数据。每次实验轮换角色。这确保所有学生都有责任并参与其中，避免依赖单一“活跃”成员。
For discipline, use a non-confrontational approach. If a student is off-task, use private, proximate correction: quietly say, 'I see you haven't started the graph yet. What's making it difficult?' Focus on the learning barrier rather than the behaviour. Maintain a positive climate by celebrating 'good mistakes' – those that reveal a common misconception and provide a learning opportunity for the whole class. Say: 'Thank you for that answer – it's exactly what many scientists used to think! Let's see how we can test it.' This normalizes error as part of science.
在纪律方面，使用非对抗性方法。如果学生走神，使用私下的、近距离的纠正：“我看到你还没开始画图。是什么让它变得困难？”关注学习障碍而不是行为本身。通过表扬“好的错误”来维持积极氛围——那些揭示常见误区并为全班提供学习机会的错误。说：“谢谢你给出那个答案——这正是许多科学家过去所认为的！让我们看看如何检验它。”这使错误成为科学的一部分而变得正常。
12. Collaboration and Resource Sharing | 合作与资源共享
Build a professional learning community within your school science department. Schedule regular 'moderation meets' where teachers compare student work against a standardized rubric, especially for practical write-ups and extended responses. This ensures consistent grading and reveals different instructional approaches to the same concept. Create a shared digital repository of resources: lesson slides, worksheets, PhET simulation guides, and model answers, organized by topic and trialled in class. Use a simple versioning system to refine materials year on year.
在学校科学部门内部建立专业学习社群。安排定期的“评分校准会议”，教师根据统一的评分标准比较学生作业，特别是对实验报告和拓展回答进行评估。这能确保评分一致性，并揭示针对同一概念的不同教学方法。创建一个共享的数字资源库：课程幻灯片、练习单、PhET 模拟指南和模型答案，按主题排列并已在实际课堂中试用。使用简单的版本控制系统逐年完善材料。
Connect beyond the school via online teacher communities like the CAIE Teacher Support hub, UK-based STEM Learning, or physics-specific forums. Share a particularly successful lesson plan, a demonstration that went well, or a tricky concept explanation. When adapting resources from others, always filter them through the lens of your specific students' needs. Peer observation is a powerful tool: invite a colleague to observe a lesson specifically looking for student engagement and questioning techniques, and reciprocate. Professional growth in physics teaching is a collaborative, continuous process.
通过在线教师社群建立学校以外的联系，例如 CAIE 教师支持中心、英国 STEM Learning 或物理学科专业论坛。分享一节特别成功的教案、一个顺利进行的演示或对一个棘手概念的解释。在借鉴他人资源时，始终要根据自己学生的具体需求进行筛选。同伴观察是一个强大的工具：邀请一位同事观摩一堂课，专门观察学生参与度和提问技巧，并予以回报。物理教学的专业成长是一个协作的、持续的过程。
