This workshop equips STEM laboratory educators with the tools to design and evaluate effective Intended Learning Outcomes (ILOs) aligned with the principles of Constructive Alignment (CA) and structured through the SOLO taxonomy (Structure of Observed Learning Outcomes). Participants will learn to critically assess and reformulate their laboratory ILOs to reflect progressive levels of student understanding, from surface to deep learning, thus promoting student-centered learning. In a hands-on format, attendees will first (re)develop ILOs for their own (digital) laboratories and then design corresponding pre- and post-tests to systematically assess learning progress. The workshop emphasizes how CA connects ILOs, Teaching and Learning Activities (TLAs), and Assessment Tasks (ATs) to ensure coherence and transparency in laboratory pedagogy. Through a guided example of a cross-reality chemical extraction laboratory, participants will explore how to construct meaningful assessments that capture changes in students’ declarative and functioning understanding. By the end of the session, educators will be able to design laboratory experiences that not only enhance student motivation and autonomy but also provide measurable evidence of learning gains, fostering deeper engagement and reflective teaching practices in STEM laboratory education.
