This study examined the following question: What is the relationship, if any, between COMPASS placement scores and the student success in the first online course during the students first semester? Discriminant function analysis was used to examine the relationship.This study used existing data from new students, who took the COMPASS placement test, and were enrolled in an online course at community colleges in Idaho, Montana, Oregon, and Washington over 5 academic years from 2010 to 2015. Data collected from the participating community colleges included COMPASS placement test scores for reading, and writing, any of the four math sections, online course(s) attempted in the first semester, age, gender, course grade, and number of credits attempted during the student's first semester.Statistically significant relationships were found between reading and writing COMPASS test scores and success in online humanities, natural science, and social science courses. For the math COMPASS scores, pre-algebra had a statistically significant relationship to success in online math courses and natural science courses. College algebra had a statistically significant relationship to success in an online natural science course. Prediction model results were just above and below 70% for each of the statistically significant relationships. The models included students who were predicted to be successful but were unsuccessful.
CoverL Division has developed a new, high-power lO0-fs laser to study solid-density plasmas. A colliding-pulse mode-locked (CPM) dye laser is used to generate tile initial laser pulses. The photograph shows the saturable absorber dye jet that modelocks the laser to provide pulsed operation from a continuous-wave pumped laser cavity. The saturable absorber consists of a 30-to 50-1_m-thick jet of DODCI dye dissolved i,, ethylene glycol. The solution is pumped through the nozzle at the top of the photograph and collected in the funnel at the bottom. The jet is enclosed by two concave mirrors, forming a subresonator that focuses the intercavity beam on the jet. Shown is tile 620-nra wavelength intercavity beam of the CPM laser. This beam is then anlplified in a series of dye and titanium sapphire amplifiers to produce 100-fs pulses with 1 J of energy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
