Performance Assisted Learning (PAL) is a teaching method that can yield great benefits—such as personal growth—all the while accomplishing immediate syllabus objectives. PAL is inspired by approaches to learning such as communicative language teaching (CLT). Kindred to CLT, PAL activities sometimes ask learners to extend themselves (for their ultimate benefit) beyond their habitual comfort zones. Without due diligence though, such activities can be difficult to evaluate and document to everyone’s satisfaction—learners, teachers, and administrators… Spreadsheets can help remedy this quandary. Unfortunately, they are an under-employed (dare I say mystery?) resource for many classroom practioners. Basic spreadsheet usage is not difficult, and teachers can use them to facilitate and actualize a realm of CLT/PIE possibilities. This Show & Tell presentation will demonstrate spreadsheet use for (a) enabling latitudes of choice for learners, (b) guiding and mentoring learners in online or face to face conditions, and (c) rapidly conveying feedback to students about their efforts.
