leslessen

Leslessen is a term used in Dutch-speaking education to describe a unit of teaching that groups together a coherent sequence of activities within a single lesson or across a block of lessons. The aim is to create a structured, observable path toward defined learning objectives, often incorporating direct instruction, guided practice, collaborative work, and formative assessment.

The word combines les (lesson) with lessen (lessons) to emphasize the content and structure of instructional time. In many contexts, leslessen function as building blocks within a larger curriculum and are planned to align with curriculum standards and assessment frameworks.

A typical lesles includes learning objectives, a teacher-led opening or warm-up, instructional activities (demonstrations, explanations, or experiments), guided practice, independent or collaborative practice, and an assessment or reflection moment. Materials and differentiation strategies are planned in advance to accommodate diverse learners. Leslessen can be delivered in person or online and may be organized as part of a daily routine or as longer blocks within a unit.

Leslessen are often compared with lesson plans (lesplan) and with broader course modules or units. Their emphasis on coherent sequencing and objective alignment reflects common practices in instructional design and curriculum development. Critics note that overly rigid leslessen can constrain creativity, while supporters argue they support consistency, assessment readiness, and inclusive teaching.
