Five levels of the ecological model, applied to a fitness instructor's work on Tucson's south side, are the substance of this HW106 Unit 3 ecological model application paper. McLeroy and colleagues' original five levels and Brown and colleagues' call for health and fitness professionals to work beyond the individual client frame the analysis. The neighborhood has hot summers, few shaded sidewalks, a broken park fountain and a school track locked after hours, and few residents meet the federal activity guidelines. One action is proposed at each level, from a goal-setting talk with new members to asking the school district to open the track in the evenings. Purdue Global HW 106 asks BS in Health and Wellness students to see their roles at more than one level. The paper ends by sorting the actions by authority and linking reach to career choice.

Unit 3 Ecological Model Application Paper

[Instructor Name]

[Date]

The student, gym, school and neighborhood are composite; the frameworks and sources cited are real.

What this part is doingContrasting the class with the neighborhood in the lead sets up the shift from individual to wider levels that the model requires.

The Ecological Model

The model treats a habit like exercise as the product of nested influences, each wrapped around the last. McLeroy et al. (1988) named five rings: what is inside the person, the people around them, the places they work or study, how a neighborhood's organizations and streets fit together and the laws and rules over all of it. The model's lesson for practitioners is that changing one level while ignoring the others rarely lasts.

Brown et al. (2023), writing for health and fitness professionals, argue that the field has concentrated on the individual level, the client in front of the trainer, and that professionals can do more for the nation's health by working at the other levels too. They point to evidence that environments, programs and policies shape whether people are active, and they encourage fitness professionals to partner with schools, employers, health departments and planners.

My Neighborhood

The neighborhood around the community gym where I teach has hot summers, few shaded sidewalks, a park with a broken water fountain and an elementary school whose track is locked after hours. Many residents work two jobs, and many are Spanish-speaking families. Federal guidance sets a weekly target of 150 moderate-intensity minutes for grown-ups and a daily hour for kids (U.S. Department of Health and Human Services, 2018). Few of my neighbors meet those targets, and the reasons sit at every level of the model.

Individual Level

What I do now. I teach classes, adjust exercises for injuries and answer questions after class.

One action. Add a five-minute goal-setting conversation for new members in their first week, asking what they want from exercise and what usually gets in the way. That moves my work from instruction toward coaching.

Interpersonal Level

The influence. Friends and family shape whether people come back. Several of my regulars started because a sister or coworker brought them.

One action. Start a "bring someone" class once a month in English and Spanish, where members invite a family member free, and pair new members with a regular for their first month.

Organizational Level

The influence. The gym's schedule fits people with standard hours; it has no classes before 6:00 a.m. or after 7:30 p.m., and no childcare.

One action. Propose to the gym's director an early-morning class for shift workers and a family class where children exercise alongside parents, solving the childcare problem in a different way.

My class is the one place in the neighborhood where I have complete control, and it is the place where I can change the least.

What this part is doingNoting the limits of the individual level before moving outward shows the writer understood the model's argument, not only its levels.

Community Level

The influence. The park is unpleasant in summer, and the only safe walking route after dark is the lit school track, which is locked.

One action. Partner with the parent group at the elementary school and the neighborhood association to run a free evening walking group at the park in the cooler months, and to ask the city parks department to repair the fountain and add shade. Brown et al. (2023) describe exactly this kind of partnership as a way fitness professionals can reach people who will never enter a gym.

Policy Level

The influence. Whether the school track can be opened depends on the district's facility-use policy and liability concerns.

One action. Join the parent group in asking the school district for an agreement that opens the track to the public on weekday evenings, an approach many districts use to share facilities with communities. I can contribute what a fitness professional knows: how many people would use it, at what times, and what supervision would make it safe.

Why the Levels Interact

The levels do not act separately. A new member's motivation, the individual level, fades quickly if the class time clashes with her shift, an organizational barrier. A walking group, a community action, works better when friends invite each other, an interpersonal effect. Opening the school track, a policy change, matters only if someone organizes people to use it. McLeroy et al. (1988) made this point when they first set out the model: programs that target one level while ignoring the others tend to produce short-lived change. For my work, it means the early-morning class, the bring-someone night and the park walking group should be planned together and promoted together, in both languages, so that each supports the others.

What I Can and Cannot Do

At the individual and interpersonal levels I can act on my own. At the organizational level I need the gym director's agreement. At the community and policy levels I would be one voice among many, and my credibility would depend on partnerships with people who already have standing, such as parents, the neighborhood association and public health staff. The model shows that the most important changes are at the levels where I have the least authority.

What this part is doingSorting the actions by how much authority the writer has makes the application realistic rather than aspirational.

What This Means for My Career Choice

Working across the levels is not equally part of every wellness role. A health and wellness coach works mainly at the individual and interpersonal levels. A community health worker works across individual, interpersonal and community levels, connecting people to resources. A health education specialist designs programs for organizations and communities and often contributes to policy. If I want to work on the park and the school track and not only in my classroom, the CHW and health education paths fit better than private coaching.

What Partners Would Need From Me

Partnerships at the community and policy levels work only if each partner gets something. The parent group wants safe places for children to play after school. The neighborhood association wants a livelier park and fewer complaints about the broken fountain. The school district wants to avoid liability and extra cost. A fitness instructor can offer free leadership of the walking group, attendance counts that show demand and a plan for supervision. Being clear about what each partner gains makes it more likely that the track opens and stays open.

Conclusion

The ecological model shows that the inactivity I see in my neighborhood has causes at every level, from individual habits to a locked school track. A fitness instructor can act at each level, with decreasing control and increasing reach. Applying the model to my own work made clear that the roles I am considering differ partly in how far up the levels they reach, and that matters for which one I choose.

The Purdue Global HW106 Unit 3 instructions

Unit 3 commonly asks students to apply the ecological model to the work of a health or fitness professional. Expect to explain the model's levels briefly, then give a realistic example of influence and action at each level for a real or composite setting. Instructors look for application beyond the individual client, since the point of the unit is that health behavior is shaped by relationships, organizations, communities and policy. Many prompts ask what the professional can and cannot do at each level and how the levels interact. A source on the model and one on the role of fitness or wellness professionals usually support the paper. The best papers connect the analysis to the student's own career path, asking which roles reach which levels.

How this HW106 Unit 3 example is built

The paper opens by contrasting one evening class with the neighborhood beyond it. A section explains the model through McLeroy and colleagues and Brown and colleagues' argument for fitness professionals. The neighborhood is described with its heat, shade, park and locked track, measured against federal activity guidelines. Each of the five levels then gets the influence and one action, under a highlighted line that the class is where the writer has complete control and can change the least. A section explains how the levels interact, followed by what partners would need. Another sorts the actions by the writer's authority. The final sections link reach across levels to the three career options and close with what the model showed.

Reading the HW106 Unit 3 grading rubric

Ecological model papers usually earn their points through application. Each level should be illustrated with a realistic influence and a specific action, not a definition. Graders reward attention to the levels beyond the individual and to how the levels interact. Honest discussion of what the professional can and cannot do, and what partners would need, shows practical judgment. Accurate use of the model's sources and of any activity guidelines cited earns credit. Connecting the analysis to career choice fits the course's purpose. Clear headings by level make the paper easy to follow. Three sources, the model, the professional application and the guidelines, should appear in APA 7.

HW106 Unit 3 help: mistakes that cost points

Many papers on this unit stay at the individual level, describing classes and personal training in detail and adding one sentence each on community and policy. Others list the levels with textbook definitions but no actions. Some propose policy changes no fitness professional could influence, without naming partners. Ignoring how levels interact misses one of the model's central lessons. Activity guideline figures are often misquoted, so check the current federal guidelines. Papers that never connect the model to the student's own role lose the course link. Before writing, walk around the setting you have in mind and note one barrier at each level. Share the setting and role, and the paper can be built from those barriers.
