School districts and educational institutions across the globe invest billions of dollars annually into professional development (PD). Yet, despite this massive financial and temporal commitment, the return on investment remains notoriously inconsistent. Too often, teacher training defaults to a passive paradigm: educators sit in large auditoriums, listen to back-to-back lectures or keynotes, and receive an avalanche of abstract information with little structural support to process, integrate, or apply what they have learned.
However, a quiet revolution is underway in educational consulting, spearheaded by experts who refuse to treat adult learners like passive sponges. Jenn White and Josh Kurzweil, co-founders of the educational consulting firm Berkeley LTC, have demonstrated that transforming teacher training does not require expensive technology or sweeping systemic overhauls. Instead, it relies on thoughtful, intentional instructional design.
Recently highlighted on the Cult of Pedagogy podcast, White and Kurzweil implemented a series of elegant, low-cost structural adjustments for a major teacher union training day attended by over 200 educators. By anchoring their design in the concept of "loop input"—teaching instructional strategies by modeling them directly to learners—they deployed three straightforward yet powerful frameworks: Pre-During-Post (PDP), Curated Q&A, and Poster Sessions.
This report examines how these foundational strategies elevate professional learning from a forgettable checkbox exercise into a dynamic, reflective, and deeply collaborative experience for K-12 and higher education institutions alike.
Detailed Chronology: Anatomy of a Transformed PD Day
To understand how these strategies work in practice, it is necessary to examine the architecture of the training day observed by presenters and participants alike. Rather than relying on a disconnected sequence of events, White and Kurzweil structured the day as an integrated continuum of learning.
Morning: Establishing Context via Pre-During-Post (PDP)
The day opened with a keynote presentation delivered to an audience of over 200 educators seated at round tables of ten. Rather than walking straight onto the stage and launching into a lecture, the event coordinators utilized the Pre phase of the PDP framework.
Pre-Keynote: For the first several minutes, table groups engaged in guided discussions addressing core questions directly related to the keynote’s central themes. Simultaneously, participants reviewed a concise outline of the upcoming presentation. This activated prior knowledge and mentally primed the audience.
During-Keynote: As the presenter spoke, attendees followed along with the structured outline, utilizing it as a flexible anchor for optional note-taking, ensuring sustained focus without cognitive overload.
Post-Keynote: Immediately following the presentation, the massive audience dispersed into breakout rooms. Crucially, these groups were intentionally mixed across different geographic regions and subject-matter specializations. Supported by trained facilitators, participants clarified concepts, shared initial takeaways, and brainstormed immediate classroom applications.
Midday: Workshops, Collaboration, and Curating Inquiry
Following the morning debriefs, the schedule transitioned into a flexible block featuring collaborative workshops, lunch, and regional networking. During the breakout and workshop sessions, embedded "instructor coaches" distributed index cards, prompting educators to jot down pressing questions, lingering curiosities, or practical dilemmas sparked by the morning keynote.
These cards were collected, reviewed, and organized to feed directly into a structured afternoon Q&A session. By filtering the questions in advance, the facilitators eliminated repetitive queries, grouped related topics into thematic clusters, and ensured that the limited Q&A time addressed the most substantive pedagogical challenges in the room.
Afternoon: Tapping Internal Expertise Through Poster Sessions
Before the final closing session and structured Q&A, the training day incorporated an interactive poster session. Rather than bringing in external authorities or relying on passive slide decks, the organizers leveraged the deep pedagogical expertise already present in the room: the instructor coaches themselves.
Coaches designed focused, visual summaries of specific teaching strategies, research findings, or classroom management techniques.
Participants rotated through various stations in small groups, engaging in dynamic, conversational deep-dives rather than listening to lectures.
This format validated the expertise of the coaching staff while giving attendees tangible, highly practical tools they could immediately adapt for their own learning communities.
Supporting Context & Metrics: The Science of Adult Learning
The success of White and Kurzweil’s design choices is not accidental; it is firmly rooted in cognitive science and decades of research into how the adult human brain processes, stores, and retrieves information.
The Problem with the "Yadda Yadda Yadda" Effect
Josh Kurzweil highlighted a pervasive flaw in traditional professional development during his interview:
"You can experience something, but then kind of yadda yadda yadda it and not really understand what just happened and how you felt."
In cognitive psychology, this phenomenon is linked to cognitive overload and a lack of consolidation time. When educators are subjected to hours of continuous lecture without structured processing pauses, working memory is overwhelmed. Information enters short-term memory but fails to undergo semantic encoding, meaning it is largely forgotten within hours or days.
Grounding in TESOL and Loop Input
White and Kurzweil trace their methodological roots to the field of TESOL (Teaching English to Speakers of Other Languages). Within TESOL training, educators frequently study loop input—a term originally coined by prominent teacher educator Tessa Woodward.
Loop input operates on a brilliantly simple premise: the medium is the message. Instead of telling teachers about collaborative learning, active engagement, or formative assessment via a lecture, professional developers experience those exact strategies as learners.
As Jenn White articulated during the podcast:
"Everything that we’re asking our instructors to do, we also want to model in the design and the delivery of our professional development."
Principles of Learning
Informed by foundational cognitive science texts—such as Daniel Willingham’s critically acclaimed Why Don’t Students Like School?—White and Kurzweil synthesized their approach into a formal set of sixteen Principles of Learning. These principles mandate that every professional learning experience must include:
Active Retrieval: Regularly prompting learners to recall prior knowledge before introducing new concepts.
Social Construction of Knowledge: Designing spaces for peer-to-peer dialogue, debate, and collaborative sense-making.
Structured Reflection: Allocating dedicated time blocks to process new ideas and connect them directly to professional practice.
Immediate Application: Bridging the gap between theoretical models and real-world execution within the span of the training day.
Official Statements & Expert Perspectives
The pedagogical insights shared by White, Kurzweil, and the observing presenters underscore a growing consensus across the educational sector: professional development must evolve from a compliance-driven administrative duty into a deeply respectful, intellectually stimulating form of adult education.

Primary Impact on PD Design
Jenn White (Berkeley LTC)
“Everything that we’re asking our instructors to do, we also want to model in the design and delivery of our PD.”
Eliminates hypocrisy in teacher training; ensures pedagogical consistency between presenter methods and teacher practices.
Josh Kurzweil (Berkeley LTC)
“You can experience something, but then kind of yadda yadda yadda it and not really understand what just happened.”
Highlights the urgent need to slow down professional learning to allow for genuine cognitive processing and metacognition.
Observing Presenter (Cult of Pedagogy)
“None of these ideas are particularly revolutionary… They’re just simple, thoughtful design choices that create more opportunities to think, talk, and learn.”
Validates that systemic improvement does not require astronomical budgets, but rather an intentional redistribution of time and conversational structures.
Future Outlook: Scaling Thoughtful PD Design in K-12 and Higher Education
As school districts, universities, and educational unions grapple with teacher burnout, retention crises, and the imperative to modernize instructional methods, the demand for high-quality professional development has never been more acute.
However, throwing more money at expensive software subscriptions, flashy keynote speakers, or rigid curriculum packages will yield diminishing returns if the underlying architecture of professional learning remains flawed. The strategies pioneered by Berkeley LTC point toward a more sustainable, human-centric future for teacher training.
Key Takeaways for Educational Leaders
Prioritize Processing Time Over Content Volume: District leaders must resist the temptation to pack every minute of a PD day with dense presentations. Cutting lecture time by 30% to make room for structured Pre-During-Post reflection dramatically increases knowledge retention and application.
Invest in Facilitator Support: The inclusion of trained instructor coaches during breakout sessions is a game-changer. Without skilled facilitation, group discussions frequently drift off-topic or lose momentum. Investing in internal leadership coaching pays massive dividends in participant engagement.
Curate, Don’t Collect: Moving away from haphazard open-mic Q&A sessions toward curated, card-based inquiry respects participants’ time and ensures that professional learning addresses the actual, collective needs of the staff.
Leverage Internal Expertise: Poster sessions featuring local educators and instructional coaches validate internal talent, foster a culture of professional community, and cost virtually nothing to implement.
Ultimately, reforming professional development is not about inventing complex new pedagogies. It is about applying the very best principles of teaching and learning to the adults tasked with educating the next generation. By slowing down the pace, structuring reflection, and honoring teachers as active, intelligent professionals, districts can transform PD from a chore into a catalyst for lasting educational excellence.
