In addition to being cost effective, studies have shown that the academic efficacy of students has been the same or even increased when utilizing OER. Among them, John Hilton III and his colleagues have conducted several large-scale studies over the years in different programs, majors and multiple colleges (Hilton, Robinson, Wiley, & Ackerman, 2014 Hilton, Gaudet, Clark, Robinson, & Wiley, 2013 Hilton, 2016 Ikahihifo, Spring, Rosecrans, & Watson, 2017). Using Open Educational Resources instead of traditional textbooks has been shown to be cost effective based on many studies. We briefly discuss research measuring these elements below. Current research on its impact measures not only Cost, but also Outcomes, Usage, and Perceptions (known as COUP Framework, Open Education Group, n.d.). The influence of OER, however, goes beyond cost. Mark Perry credits Open Educational Resources publishers as responsible for this historical break in the trend (Perry, 2017). While speculating about possible reasons, Dr.
In 2017, for the first time, prices have stopped rising and started to decrease. The price of textbooks has risen steadily, increasing more than 1000% since 1977 (Popken, 2015). Students enrolled in OER courses performed better than those enrolled in the same courses using a commercial textbook. Some professors felt that the textbook lacked important content, but because of its openness, they added their own content to the book. The students’ perception was very positive, and faculty’s opinions on the textbooks used were mixed. This pilot program delivered strong results. To measure the results, we surveyed students and conducted a faculty survey and a focus group, in addition to analyzing the students’ final grades. Furthermore, we highlight the successes and shortcomings in having the library as a central OER partner.
We discuss the pedagogical changes as well as explore the impact of Open Educational Resources (OER) on students’ savings, their academic outcomes and perceptions of OER. The differences are purely cosmetic.This case study describes the library’s experience of collaborating with an undergraduate Psychology Department at Touro College to integrate open textbooks into their program. This option is the pie and exploded pie types in three dimensions, tilted slightly away from the viewer for a more dramatic appearance. The only difference is that the breakup of the combined slice is shown in a separate stacked bar, instead of a separate pie. The bar of pie subtype is almost the same as the pie of pie subtype. This chart is great for emphasizing specific data it's demonstrated in the next chapter. With this subtype, you can break out one slice of a pie into its own, smaller pie (which is itself broken down into slices). This technique uses the ordinary pie subtype, as explained in the next chapter. Usually, Excel charting mavens prefer to explode just a single slice of a pie for emphasis. The name sounds like a Vaudeville gag, but the exploded pie chart simply separates each piece of a pie with a small amount of white space.

The basic pie chart everyone knows and loves, which shows the breakup of a single series of data.
If you create a pie chart that uses one or more negative values, the negative values will be converted to positive values-which is probably not what you intended! The values used in a pie chart must all be positive numbers.
A pie chart with too many data points can be very difficult to interpret. Generally, a pie chart should use no more than five or six data points (or slices). Pie charts are most effective with a small number of data points. A pie chart is useful when you want to show relative proportions or contributions to a whole.
