Lower teaching evaluations can affect students’ willingness to recommend an online course. To maintain online course quality, it is important to keep the “integrity” of a course, that is, offer to the extent possible, the same content and learning outcomes in an online course as the face‐to‐face (F2F) equivalent. This study explored the impact of background, technological, and course‐related variables on perceived favorability of online (versus F2F) courses and willingness to recommend courses using two independent “mixed course format” samples of business undergraduates, that is, simultaneously taking online/hybrid and F2F courses. Participants were recruited based on their enrollment in at least one online or hybrid course. A complete data sample of 259 students filled out an online survey in the Fall 2015 semester, followed by a second independent sample of 269 students in the Spring 2016 semester. Hierarchical regression results showed that after controlling for background variables, one course‐related variable (instructor effectiveness) and one technological‐related (perceived ease of use) consistently explained perceived favorability of online (versus F2F) courses across both samples. For the willingness to recommend courses, after controlling for background variables, both course‐related variables (instructor effectiveness and student motivation) and the perceived favorability of the online course were each significant across both samples.  相似文献

Multiple myeloma (MM) is diagnosed and monitored by correlating panel of test results including serum Protein electrophoresis (SPE), Immunofixation electrophoresis (IFE), serum Free Light chain (sFLC) measurements. This audit is aimed to evaluate the prevalence of non-correlation and discrepancies amongst the three investigations (SPE/IFE/sFLC) for assessment of MM. 106 MM patients were reviewed over 16 months in a tertiary cancer care center by the availability of 3 serum test results (SPE/IFE/sFLC). Patients were divided into 2 groups: group1, newly diagnosed MM patients who were yet to receive myeloma specific treatment (n = 48); and group2, already diagnosed MM patients on treatment and followup (n = 58). Treatment modalities included stem cell transplantation and standard chemotherapy regimens. Non-correlation between the three test results (IFE/SPE/sFLC) was observed (21% in group1 and 45% in group2). Three types of discrepancies were detected as follows: (a) IFE showing less number of restriction bands as compared to SPE (8.6% patients in group2); (b) SPE/IFE negative with an abnormal sFLC ratio (12.5% patients in group1 and 13.7% in group2); (c) SPE/IFE positive but normal sFLC ratio (8% in group1 and 22% in group2). To conclude, IFE may sometimes provide information that does not always correlate with either of the SPE or sFLC results due to different sensitivities, antigen–antibody interactions, or treatment. Hence, SPE plus sFLC may be more useful particularly for patients on follow-up while IFE plus sFLC may help screen the new patients. The judicious selection of the biochemical assays can effectively reduce the treatment cost in a developing country like India.  相似文献

Hampshire LEA has carried out two longitudinal studies: from reception intake to the end of Year 2, and from the end of Year 2 to the end of Year 6. A total, respectively, of 161 and 114 schools and about 6400 and 4700 pupil records have been analysed. Test scores at baseline (entry to reception), Key Stage 1 and Key Stage 2 have been used, together with pupil and school level variables. Multilevel models have been fitted and show that schools differ along several dimensions, both by curriculum subject and by prior attainment of pupil. The research sought ways of communicating the results to head teachers in ways which were meaningful without destroying the underlying complexity of the relationships uncovered. The paper describes how this can be done, in ways which can assist the process of school improvement.  相似文献
