When teachers are clear about what success looks like and what evidence will show it, instruction becomes focused and responsive. Effective lessons share a set of essential components that work together to support learning. These components do not prescribe a script or template, nor are they a lesson plan to be followed step by step. Instead, they offer a way for teachers to think more deliberately about how learning is designed and supported.
The TIRES Framework: What Effective Lessons Share
TIRES is an organizing framework we created for instructional thinking. It identifies five components of effective lessons across grade levels and content areas: Tasks, Input, Responses, Evidence, and Success. The components do not need to be addressed in a fixed order, and much like the tires on a car, they are in rotation. What matters is that none of them are overlooked—because when one component is missing or underdeveloped, learning becomes harder to see and support. Let’s take a closer look at the individual components.
Evidence
Evidence is the anchor of effective lesson design. If we don’t know what evidence we’re looking for, we won’t recognize learning when it happens (Almarode et al., 2025). In the TIRES framework, evidence refers to the observable indicators that show students have met the learning intention. Evidence is not the same as activity completion or engagement. A student can be busy and compliant without demonstrating understanding. Instead, evidence is intentional, aligned, and elicited through carefully designed opportunities for students to reveal their thinking. When teachers begin with evidence, instructional decisions become more precise. They ask, What will students say, write, create, or do that demonstrates learning? The answer shapes the rest of the lesson.
Success
Success clarifies what learning looks like from the student’s point of view, and success criteria are aligned to the learning intention and written in language students can use to monitor their own learning. When success is broken into manageable increments, students are more likely to persist and make adjustments during the lesson. For teachers, incremental success criteria provide a clearer window into student understanding, allowing feedback and support to be targeted. When progress is visible, learning becomes more intentional and more likely to stick.
Input
Input refers to what students need before they are asked to demonstrate learning. This includes explanations, models, examples, demonstrations, and think-alouds that support understanding. Too much input can limit thinking, while too little leaves students without a clear path forward. In the TIRES framework, input is calibrated to prepare students for the task ahead, not to remove all challenge. It can be planned in advance or adjusted in the moment as teachers observe student responses. When input is well aligned, students are more likely to engage in productive struggle and demonstrate meaningful learning.
Tasks
Tasks are the means through which students produce evidence of learning. In effective lessons, tasks are selected because they align to the evidence teachers are seeking and the success criteria students are working toward. A well-designed task surfaces student thinking and allows both the teacher and the learner to determine whether progress is being made. In TIRES, tasks give students an opportunity to apply input, work toward incremental success criteria, and demonstrate understanding in observable ways. Thoughtful task design ensures that time spent working translates into information teachers can use to respond instructionally.
Responses
Responses are where instruction and assessment meet. They are the moments when students show what they understand, and teachers gather information about learning in progress. Responses can take many forms, including speaking, writing, drawing, or demonstrating, but all are planned deliberately and are connected to the evidence teachers are seeking. Teachers attend to patterns across student responses, not just correctness, and use that information to decide whether to extend, clarify, or adjust instruction (Fisher & Frey, 2021). Responses also support student reflection by helping learners recognize progress toward incremental success criteria.
TIRES in Action
In the video that accompanies this column, 8th grade science teacher Allyson Sorenson from Avondale Elementary School District in Glendale, Arizona, leads a lesson about heat transfer. Her evidence of learning requires hypothesis generation, so the task she has designed does just that: She solicits hypotheses from her students but does not tell them whether they are correct or not. Instead, she allows them to return to the data time and again to examine it for patterns. She uses incremental success criteria to move learning forward, providing input as needed.
When lessons like Sorenson’s run on TIRES, teachers spend less time guessing and students spend more time learning.
