Daily Learning Contract
- Topic: Evidence-First Notes
- Objective: Students will identify how evidence-first written communication transfers from HVAC service notes to another career.
- TEKS: d(4)(B)
- Demonstration of Learning: Four fictional service notes and one written-communication transfer response.
Time: 50 minutes
TEKS: d(4)(B)
Evidence: four fictional service notes and one transfer sentence
Before class
Per student: FYF workbook pp. 185–190, pencil, and one Canvas-capable device to view the locked tickets and submit privately. Print the six-page safe-label fallback only for a student without the workbook or needing enlarged access. Students never complete both surfaces. Notes are independent; pairs may rehearse one bounded sentence. Collect one workbook upload/typed route or one fallback packet per student.
Project this non-ticket model: The note states that one room feels warmer and shows a partly blocked return area. This could be consistent with restricted airflow, but one image does not prove the cause. A qualified HVAC professional checks the full airflow path and system conditions. Never ask students to inspect, diagnose, reset, clean, or repair real equipment.
50-minute flow
- Warm-up, 5 min. What makes a work note useful to the next person?
- Evidence language, 8 min. Relabel the FYF fields before students write: keep Observation; treat Diagnosed problems as Supported possibility; treat Action as Evidence limit + qualified next check.
- Parts reference, 7 min. Use the workbook reference to locate filter, indoor coil/evaporator, outdoor condenser, and airflow evidence. This is vocabulary, not technician authorization.
- Four tickets, 25 min. Students complete FYF pp. 187–190 or the safe-label fallback. They may say “could be consistent with” but may not claim a complete diagnosis from one image.
- Exit, 5 min. Rewrite one vague note into an evidence-first note and explain how the same written-communication skill transfers to another career.
Teacher interpretation guide
- Ticket 1: visible ice buildup and weak cooling/airflow. This could be consistent with restricted airflow or another system issue. The image does not determine the root cause; a qualified HVAC professional checks airflow, filter, coil, and other system conditions.
- Ticket 2: visibly heavy dust/debris on the indoor coil with uneven airflow. A qualified professional evaluates cleaning and the complete airflow path.
- Ticket 3: visibly dirty filter plus supplied weak/dusty airflow. The evidence strongly supports a restricted filter, but students still route service to the authorized adult/professional rather than performing classroom repair directions.
- Ticket 4: visibly weathered/dirty outdoor unit with insufficient cooling. The photo does not prove the failed component. A qualified professional evaluates the condenser and full system.
Accept other careful interpretations tied to the supplied evidence. Do not reward confident guessing over a bounded claim.
Monitor, pivot, and trim
- Minute 13: Students have relabeled Diagnosis as Supported possibility and Action as Evidence limit + qualified next check. If one-third write certain diagnoses, project the non-ticket model and circle could, does not prove, and qualified.
- Minute 30: Tickets 1–2 include evidence, possibility, limit, and next check.
- Minute 42: All four tickets are complete.
- Safe trim: Accept one precise sentence across the four labels per ticket. Do not drop a ticket, limit, next check, or transfer response. Use the final five minutes for transfer, collect one route, and close devices.
Access route
Every ticket is embedded with neutral alt text and adjacent complaint/extra-information text. Allow workbook, zoom, read-aloud, typed response, dictation, or the enlarged fallback. No personal home/HVAC story is required.
