Background: The popularised notion of models-based practice (MBP) is one that focuses on the delivery of a model, e.g. Cooperative Learning, Sport Education, Teaching Personal and Social Responsibility, Teaching Games for Understanding. Indeed, while an abundance of research studies have examined the delivery of a single model and some have explored hybrid models, few have sought to meaningfully and purposefully connect different models in a school's curriculum (see Kirk, D. 2013 Aim: To provide a first empirical insight into using a MBP approach involving several models to teach physical education. At its heart, this paper presents the reader with the realistic and nuanced challenges that arise in striving towards, engaging with, planning for, and enacting a broader, multimodel notion of MBP. Method: While the study itself was broader, we focus primarily on three units (one using Cooperative Learning, one using a Tactical Games/ Cooperative Learning hybrid and a third using Sport Education) taught to boys in two different age groups (i.e. 11-12 and 14-15). Two analytical questions inform and guide our enquiry: (1) What do we learn about MBP implementation through this project that would help other physical education practitioners implement a multimodel MBP approach? and (2) What are the key enablers and constraints of early MBP implementation? Data sources included (a) 21 semi-structured interviews with student groups, (b) teacher post-lesson and post-unit reflective analyses, (c) daily teacher reflective diaries, and (d) teacher unit diaries. Data were analysed comparatively considering the two analytical questions. Results: The data analysis conveys strong themes around the areas of teacher and student prior learning, working toward facilitating a change in practice, sufficient time to consider changes in practice, and changing
