In the current world of percentages and averaging percentage points, finding a way to measure concepts like grit and effort is daunting. For instance, all of us in the group loved the idea of allowing students to redo and redo work until they achieve mastery. But, how is that possible when grades are closed at numerous seemingly arbitrary cut-off dates (end of a quarter, cycle, semester, etc.)?
How would this assessment model address the learning process? To avoid centering on results, this cafeteria-style model would remove the time limits imposed in the traditional classroom. So, instead of assigning projects/essays/etc. and setting specific due dates, the teacher would make the list of assessment options available to students at the beginning of the school year. Then, students could choose the way they want to present their learning and work on it (redoing and redoing as necessary) and then submitting the work, when they are satisfied with it, throughout the school year.
Beginning in the fall of 2021, Harrisburg Area Community College (HACC) was forced to examine and revise its traditional model of student success and particularly its reliance on the cafeteria model as the result of declining enrollment and retention rates, stagnant completion, a review of Title IV compliance, and an overarching need to improve student success outcomes. HACC recognized the importance of adopting best and research-based practices in student support delivery, and, over the years, several incremental changes have been made to operationalize a variety of student success practices and to improve student outcomes. These changes included but were not limited to the adoption of a relational advising approach, the utilization of advising curriculum clusters, and a shared advising model (faculty advisors, professional academic advisors, and success coaches).
To address this issue and promote greater student success and completion, HACC moved to implement enhancements after a thorough review of the issue in the fall of 2021. These steps included the following:
Required educational plans for all students. The most important enhancement was requiring all students to have an electronically recorded educational plan. That move was new for HACC, but it was necessary to help foster student success. This move was phased in over several semesters.
Creation of a working group to address the issue. This working group included members from advising, the welcome center, financial aid, student success, and registration and records. This working group attacked the problem in this manner.
Offered professional development for the educational planning process and on-demand resources to faculty advisors and professional advisors. Advisors needed to have training and tools to support students and the creation of their educational plans.
Coupled the new educational plan process with an early registration push. HACC knew that part of its retention issue was with students waiting to register, so it created campaigns to get students to register early using their new educational plans.
Identified data needed to track progress. HACC knew its teams needed to use data and metrics to ensure the new educational plan process was working as designed to support student success. Therefore, it began tracking the following data points relative to this new process.
Delegated responsibilities. To ensure success, HACC assigned each team member in the working group (and others within the Student Success division) specific tasks related to the new educational plan process. The college then tracked progress with short weekly check-in meetings.

Obesity has reached epidemic proportions worldwide and reports estimate that American children consume up to 25% of calories from snacks. Several animal models of obesity exist, but studies are lacking that compare high-fat diets (HFD) traditionally used in rodent models of diet-induced obesity (DIO) to diets consisting of food regularly consumed by humans, including high-salt, high-fat, low-fiber, energy dense foods such as cookies, chips, and processed meats. To investigate the obesogenic and inflammatory consequences of a cafeteria diet (CAF) compared to a lard-based 45% HFD in rodent models, male Wistar rats were fed HFD, CAF or chow control diets for 15 weeks. Body weight increased dramatically and remained significantly elevated in CAF-fed rats compared to all other diets. Glucose- and insulin-tolerance tests revealed that hyperinsulinemia, hyperglycemia, and glucose intolerance were exaggerated in the CAF-fed rats compared to controls and HFD-fed rats. It is well-established that macrophages infiltrate metabolic tissues at the onset of weight gain and directly contribute to inflammation, insulin resistance, and obesity. Although both high fat diets resulted in increased adiposity and hepatosteatosis, CAF-fed rats displayed remarkable inflammation in white fat, brown fat and liver compared to HFD and controls. In sum, the CAF provided a robust model of human metabolic syndrome compared to traditional lard-based HFD, creating a phenotype of exaggerated obesity with glucose intolerance and inflammation. This model provides a unique platform to study the biochemical, genomic and physiological mechanisms of obesity and obesity-related disease states that are pandemic in western civilization today.
Many promising findings from pre-clinical research have failed to translate to the clinic due to their inability to incorporate human disease co-morbidity. A variety of rodent diets and feeding durations are currently used in models of human metabolic syndrome, obesity and diabetes. One model, the Cafeteria (CAF) diet, makes use of grocery store-purchased food items that more closely approximate the human ultra-processed diet than commercial high-fat or high-sugar rodent diets. The present study describes the development of metabolic syndrome in rats fed a CAF diet as well as the recovery of metabolic syndrome following a healthy "lifestyle" change. In addition, we explored the effects of CAF diet on spatial learning and memory and on neuroinflammation. Three-week old male Sprague-Dawley rats were fed a CAF diet for three months that consisted of 16 highly palatable human food items along with standard chow and a 12% sucrose solution to mimic soda consumption. Thereafter, a sub-group of CAF diet rats was switched to a chow diet (SWT) for one month. Both CAF and SWT groups were compared to control rats maintained on a standard chow diet (SD). Prior to the diet switch, CAF and SWT animals developed features akin to metabolic syndrome. Both groups of rats displayed significant abdominal obesity with increased visceral adiposity, hyperinsulinemia, glucose intolerance and dyslipidemia with elevated serum triglyceride levels and reduced HDL cholesterol. Switching to a chow diet for one month completely reversed these features in SWT animals. Although acquisition of the Barnes maze was not affected by the CAF diet, these animals exhibited greater hippocampal neuroinflammation compared to both SD and SWT rats as assessed by Iba1 staining. These results demonstrate that the CAF diet is very effective in creating metabolic syndrome with hippocampal inflammation in rats over a relatively short time span. This model may be of great heuristic importance in determining potential reversibility of metabolic and cerebrovascular pathologies across the lifespan and as a co-morbid factor in other disease models such as stroke.
"A cafeteria plan is an employee benefits plan that allows employees to choose among a variety of options to create a benefits plan that best meets their needs and those of their family. In a cafeteria plan, an employee receives a certain amount of money from the employer to "purchase" particular components of a benefits plan".

Genetic models of obesity, such as ob/ob mice and db/db mice, have proved to be useful to elucidate the underlying mechanisms of many associated pathologies. However, obesity models induced by feeding rodents with a hypercaloric diet are widely used by investigators for preclinical testing of therapeutic agents because they closely mimic human obesity owe to their polygenic background. Two common variations include the high-fat diet, which causes obesity due to its high energy density, and the cafeteria diet, which stimulates hyperphagia (and subsequent obesity) due to its palatability.
