TILT
Transparency in Learning and Teaching
Developed by Dr. Mary-Ann Winkelmes, TILT is a small, high-leverage change to how assignments are written. Many students, especially those first in their family to attend college, struggle not because the work is too hard but because the unwritten rules of the assignment are unclear. TILT fixes that by making three things explicit on every assignment. It is deliberately lightweight: transparency, not more work.
- Purpose — why am I doing this? The skills students practice, the knowledge they gain, and how it connects to real life and course outcomes.
- Task — what exactly do I do? The steps to follow, what to do and what to avoid, and any productive-struggle steps left open on purpose.
- Criteria — how is it judged? A checklist or rubric, what a successful piece looks like, and annotated examples of real work.
An AAC&U pilot (2014–15) across 7 minority-serving institutions, 1,180 students and 35 faculty, found that applying TILT to just two assignments produced statistically significant gains of medium-to-large magnitude in academic confidence, sense of belonging, and skill mastery, with the largest gains for first-generation, low-income, and underserved students (Winkelmes et al., Peer Review, AAC&U, 2016).
How to apply it
- Design assessments using the three headings. Structure each assignment as Purpose / Task / Criteria, often just reorganizing what already exists.
- Name the real-world relevance. State the durable skill the task builds and how it links to a course outcome, so the work feels worth doing.
- Add annotated exemplars. Show one or two samples of successful work with notes on why they succeed.
- Start small. The research shows the effect from TILTing as few as two assignments; pick the highest-stakes ones first.
Quick self-check before publishing an assignment
- Could a first-generation student, reading only this prompt, explain why the assignment matters?
- Are the steps and the “what to avoid” spelled out?
- Is there a rubric or checklist, and at least one example of success?
Pairs with the two-lane model. Once a task sits in the open (AI-permitted) lane, TILT is where you make the AI rules explicit: the Task section states exactly how students may use AI, and the Criteria reward their judgment over the raw AI output.

Two-Lane
Thinking about two purposes for assessment
Why we’re sharing it. We think this model offers a promising way to conceptualize assessments within a course and within a program. It is important to the workshop and will organize much of our work together. But we also want to know what you think of it: would you refine it? Revise it? Reject it? In short, we are asking that you work with this model, but not that you do so uncritically.
The two-lane model (University of Sydney; Danny Liu and Adam Bridgeman, 2024–2025) starts from a simple premise: assessment now has to do two jobs at once. It must assure, in the accreditation sense of providing trustworthy evidence, that students actually achieved the learning outcomes, and it must help students learn to work productively with AI. One assessment type cannot do both jobs well, so the model sorts every assessment into one of two lanes. Lane 1 assessments are secure and supervised; they may restrict or prohibit AI use, though a ban is not required. Lane 2 assessments are open, allowing instructors to assess a course’s learning outcomes as students will actually encounter them, in a world where AI tools are available.
Our context: online and asynchronous. Lane 1 is defined by controlled conditions, not by a physical room, so the model fits async online directly. Online, we achieve “controlled” through course and platform design. The specific methods are an area our team should continue to refine to meet our learners’ needs and our model.
Lane 1 — Controlled (Assessment of Learning). The conditions are controlled enough to assure the work reflects this student’s own capability. The distinction is about conditions and purpose, not location.
- AI may be banned, restricted, or deliberately permitted in specified ways, depending on the learning outcome being assured.
- Options include identity-verified time-boxed tasks, authenticated performance work, and other methods, an area our team should continue to refine.
- Purpose: a defensible signal of genuine achievement.
Lane 2 — Open (Assessment for and as Learning). Uncontrolled conditions, where AI use is permitted and even encouraged. This lane still assesses the course’s own learning outcomes. Students demonstrate their skills and knowledge in the environment where they will actually use them, while also developing AI literacy: evaluating, refining, and taking responsibility for AI output rather than simply submitting it.
- Authentic, process-focused, real-world tasks, the natural home of most async coursework.
- Guide AI use as a menu, not a traffic light: don’t micro-restrict; steer students toward the choices better for learning.
- Process artifacts (drafts, AI chat logs, reflections) make the thinking visible.
- Purpose: develop and assess students’ skills and knowledge in an AI-rich environment, building AI-capable graduates along the way.
The key move: assign lanes at the assessment level. Lane assignment is a course-level, assessment-by-assessment decision guided by each task’s purpose (program-level coordination is optional). Put controlled assessment only where an outcome genuinely needs to be assured, and let most of the course live in the open lane. A single task can combine both, for example an open project capped by a short controlled check. Lane 1 options are an area our team should continue to refine to meet our learners’ needs and our model.
Pairs with TILT. The two-lane model decides which lane a task lives in; TILT makes the rules of that lane explicit to students, especially the open lane, where “how may I use AI here, and how will it be graded?” must be stated plainly.
How to apply it in an async course
- Consider each assessment on its own. Does the learning outcome call for controlled conditions, or would students benefit from working with AI? Label the lane for students.
- Choose the control method deliberately. Where a task is controlled, work with the design team to select a method that fits; the method is deliberately left open here and should be refined over time.
- Make the open lane AI-authentic. If AI can complete the task in one shot with no learning, redesign it around the student’s judgment and critique of AI, and collect the process, not just the product.
- Focus on developing AI literacy rather than relying primarily on detection. Lead with clear expectations and AI-integrated design, and state AI-use rules plainly in every brief.
Common misreads to avoid
- Lane 1 is not “in person” and does not have to be “no AI.” It means controlled conditions to assure authorship; AI may be restricted or purposefully permitted within them.
- Lane 2 is not “unsecured” or a free-for-all. Open tasks are deliberately designed for critical, responsible AI use.
- Consider where controlled conditions are truly necessary. Controlling every task raises cost and anxiety and crowds out authentic learning; aim for proportion, not maximum surveillance.
