The Flex Model
The Flex Model of Blended Learning is a model that is often used to decrease dropout rates as well as programs for upgrading or increasing school credits (Rambo, 2011). In this model, the majority of the learning is done online, although students may be expected to complete offline activities sometimes. The students and teachers work at a shared site, with the teachers providing support and extensions as needed. Homework is completed off the school site (Horn & Staker, 2014). The students' programs are customized, and flexible and are taught in a variety of forms. Student support is provided as needed (Horn & Staker, 2017).
Enriched Virtual Model
With the Enriched Virtual Model, students are able to take courses that require face-to-face learning, but students are permitted to do their learning activities in a place of their choosing. The students and teachers meet on a regular schedule but rarely every day (Horn & Staker, 2015; Cordero et al., 2021). These meetings are a required part of the course and are not optional meetings. This model allows students the opportunity and freedom to manage their learning time and speed in the way that works best for them (Nafl'ah et al, 2022). Online classes may occur synchronously, where the students and teacher work together, or asynchronously, where the learning occurs independently, and lectures are recorded (Cordero et al., 2021).
A La Carte Model
When participating in an A La Carte Model of Blended Learning, students attend their regular school while also attending one or more fully online courses as well. This model provides students the opportunity to take classes that may not be offered at their regular school while also providing more opportunities to adapt their timetables (Horn & Staker, 2015; Chukwuemeka et al., 2020). This model allows courses to be made available to students who live in rural areas where smaller schools may not have the ability to provide courses that students want or need to improve their qualifications for post-secondary admission (Horn & Staker, 2015). In addition, the A La Carte Model has relevance in both education as well as in the professional world where employees can take courses while driving or in the comfort of their own homes (Chukwuemeka et al., 2020). It allows people to control the time, pace, and space of their learning, an important aspect of Blended Learning.
