Experimental Lessons in the PEN System
Improving Student Learning and Teacher Practice Together
In many schools, professional development sits outside the classroom. Workshops are attended, ideas are discussed, and strategies are shared—but what happens in daily teaching often remains unchanged.
The PEN (Professional Educators Network) system takes a different approach. It places professional development where it matters most: inside the classroom, through structured, purposeful practice.
At the center of this approach are experimental lessons.
An experimental lesson is designed to address a clearly identified learning need within the school. This may be a gap in literacy, a weakness in numeracy, a need to strengthen critical thinking, or a focus on social-emotional learning. The lesson is intentional, evidence-informed, and aligned with the school’s strategic plan.
This is the first prong: improving student learning through targeted intervention.
The second prong is equally important and often overlooked. The experimental lesson is also designed to improve the teacher’s own methodology.
Teachers begin with self-reflection. Using a tool such as Danielson’s Framework for Teaching (FFT), they identify an area of their own practice that requires development. This may include questioning techniques, differentiation, pacing, or classroom management. The experimental lesson then becomes a vehicle for working deliberately on that aspect of teaching while still addressing a specific learner need.
In this way, the lesson serves two purposes at once. It is not only about what students learn, but also about how the teacher facilitates the learning.
As with all PEN processes, the lesson is not done in isolation.
Teachers share their plans with their PLC, outlining both the targeted student learning need and the aspect of their own practice they are working to improve. After the lesson, the discussion focuses on what actually happened. How did students respond? Was the intended learning achieved? Did the teacher’s chosen strategy strengthen their own practice?
Not all experimental lessons are successful—and that is precisely where their value lies.
Students may respond in unexpected ways. A strategy aimed at improving classroom management, for example, may not produce the intended effect, requiring the teacher to adapt in the moment. These experiences provide rich material for reflection and discussion within the PLC.
Other lessons are highly successful. Students engage, demonstrate deeper understanding, and respond positively to the teacher’s refined approach. These lessons often reveal effective methodologies that can be extended and adapted across other classrooms.
In both cases, the practice is always shared.
This shared reflection strengthens the entire PLC. Teachers recognize patterns, anticipate challenges, and refine strategies together. A method that did not work in one context can be adjusted based on collective insight. A successful approach can be adopted and scaled.
Over time, this creates a culture where teaching is not private, but continuously examined and improved.
Successful lesson designs, along with reflections on teacher practice, are documented and added to a schoolwide shared database. This ensures that both effective strategies and valuable lessons learned from challenges contribute to the school’s collective knowledge.
During professional development days, PLCs present their most effective methodologies to the wider staff. These presentations are grounded in real classroom experience and demonstrate how both student learning and teacher practice have improved.
The impact is twofold and powerful.
Students benefit from targeted, responsive teaching that addresses real learning needs. At the same time, teachers become more reflective and intentional in their practice, using structured frameworks to guide their growth.
This is the strength of the PEN system. It is a two-pronged approach: improving student learning while simultaneously refining teacher methodology. Each lesson becomes an opportunity not only to teach, but to learn—individually and collectively.

PEN 系統中的實驗性課堂：同時提升學生學習與教師教學實務
在許多學校中，專業發展往往存在於課堂之外。教師參加研習、討論理念、分享策略——但日常教學中的實際情況往往沒有真正改變。
PEN（專業教育者網絡）系統採取不同的做法。它將專業發展放在最重要的位置：透過有結構且有目的的實務，直接在課堂內進行。
這個方法的核心是實驗性課堂。
實驗性課堂是為了解決學校中明確辨識出的學習需求而設計的。這可能是讀寫能力的不足、數學能力的弱點、需要加強批判性思維，或是關注社會情緒學習。課堂設計具有明確目的，依據證據，並與學校的策略計畫保持一致。
這是第一個面向：透過有針對性的介入來提升學生學習。
第二個面向同樣重要，但常被忽略。實驗性課堂同時也是為了提升教師自身的教學方法。
教師從自我反思開始。透過如 Danielson 教學架構（FFT）等工具，他們辨識出自身教學中需要改進的面向。這可能包括提問技巧、差異化教學、節奏掌控或班級經營。實驗性課堂因此成為一個載體，使教師在回應特定學習需求的同時，有意識地改進自身的教學實務。
透過這樣的方式，一堂課同時達成兩個目的。它不僅關乎學生學到了什麼，也關乎教師如何促進學習的進行。
如同所有 PEN 的運作流程，課堂不會在孤立的情況下進行。
教師會在 PLC 中分享課堂設計，說明所針對的學生學習需求，以及自身希望改進的教學面向。課後的討論聚焦於實際發生的情況。學生如何回應？預期的學習是否達成？教師所採用的策略是否強化了自身的教學實務？
並非所有實驗性課堂都會成功——而這正是其價值所在。
學生可能出現未預期的反應。例如，一個旨在改善班級經營的策略，可能未能產生預期效果，教師需要在課堂中即時調整。這些經驗為 PLC 的反思與討論提供了豐富的素材。
也有一些課堂非常成功。學生投入其中，展現更深層的理解，並對教師調整後的教學方式產生正向回應。這些課堂往往揭示出可在不同班級中延伸與應用的有效教學方法。
無論成功或否，實務都必須被分享。
這種共享的反思強化了整個 PLC。教師能辨識模式、預見挑戰，並共同調整策略。在某個情境中未奏效的方法，可以透過集體的洞見加以修正；成功的方法則可以被採用並擴展。
隨著時間推進，這樣的運作會形成一種文化：教學不再是個人的，而是持續被檢視與改進的專業實務。
成功的課堂設計，以及對教學實務的反思，會被記錄並納入全校共享的資料庫。這確保了有效策略與從挑戰中獲得的寶貴經驗，能夠成為學校的集體知識。
在專業發展日中，PLC 會向全體教師呈現最有效的教學方法。這些分享建立在真實課堂經驗之上，並展現學生學習與教師教學實務如何同時獲得提升。
其影響具有雙重且強而有力。
學生從針對性且具回應性的教學中受益，學習需求得到真正的關注。同時，教師也變得更加具反思性與目的性，透過結構化的架構引導自身專業成長。
這正是 PEN 系統的優勢。這是一種雙軌並進的方法：在提升學生學習的同時，持續精進教師教學方法。每一堂課不僅是教學的機會，更是學習的機會——對個人與整個團隊而言皆然。
