Force	Tension
Common offer and different entrants	Reusable content reduces repeated development, while differences in preparation or access can require different routes.
Competent account and acquisition	A precise method account can support competent use while leaving a novice unable to acquire the required operation.
Whole tasks and manageable effort	Whole tasks preserve meaning and selection, while missing prerequisites or excessive simultaneous demands can prevent useful practice.
Other people’s contribution	Peers and providers can improve available reasoning or feedback while concealing the learner’s missing contribution.
Content and medium	A medium can make an operation accessible while adding production, access and maintenance costs without changing learning.
Scale and support	More learners can share fixed development costs while increasing individual checking, peak demand and recovery work.
Early comparison and stronger claims	A constructed route can expose a defect before delivery, while actual learning, transfer and causal effectiveness require their own observations.
