Since the availability of lecture recordings, there have been limited studies of any associations between face-to-face lecture attendance and academic outcomes. The aims of the study, in an introductory pathophysiology course, where lecture recordings were available, were 1) to quantify lecture attendance and any associations between academic outcomes and lecture attendance, and 2) to determine why students do or do not attend lectures. Data were analyzed for the whole cohort before separating the nursing (∼60%) and nonnursing students. Of 288 enrolled students, 205 consented to sign the attendance register, and 139 to undertake the online survey. Lecture attendance was higher (41%) before the midsemester exam than afterwards (24%), P < 0.001, due to higher attendance by the nursing than nonnursing students. Students who attended ≥50% of lectures consistently got higher academic outcomes than those that attended <50%, e.g., examinations, 11 percent points higher. Pearson’s or Spearman’s correlation coefficients for students from both the sign-in and survey showed that there were positive associations between lecture attendance and academic outcomes, which were mainly weak for nursing students ( P ≤ 0.05), with no association for nonnursing students. From the survey, most students who attended lectures did so because they considered they learned more by attending lectures, whereas not liking the lecture time was the most common reason for not attending lectures. In conclusion, even though students have access to lecture recordings, lecture attendance is still a determinant of academic outcomes for some students of pathophysiology.

The One

The effect of lecture recordings on academic outcomes is not clear, and it is not known whether lecture recordings alter the association between attending lectures and academic outcomes. In a third-year pharmacology course, 39 of 42 students consented to the study. Sixty percent of the students attended the first lecture monitored, and then lecture attendance declined to an average of 41%/lecture. The final marks were significantly higher for students who attended ≥ 50% than those who attended < 50% of lectures. There was a weak positive association between lecture attendance and the final course mark in pharmacology. Thirteen of the 39 students did not access any lecture recordings, and an additional 10 students did not access any lecture recordings to ≥ 60% completion. For the 26 students who accessed the lecture recordings, there was a weak negative association between number of lectures accessed to ≥ 80% completion and final mark, but no correlation when the one student who failed the course was removed from the analysis. From this study, it does not seem that lecture recordings can be used as an effective replacement of face-to-face lectures. As lecture recordings were accessed more by the students who subsequently had poorer outcomes, it is possible that they would have had even poorer outcomes without this access.

The Relationship

Historically, lecture attendance was considered a predictor of better academic outcomes. However, it is not known whether this is true for the human biosciences or whether it still applies with the introduction of lecture recordings. The aims were to determine (i) any association between lecture attendance and academic outcomes for students studying the human biosciences, and (ii) whether this was altered by the availability of lecture recordings. There were 27 studies of the association between lecture attendance and academic outcomes in 32 courses, and for 24 courses (75%) there was a positive association. The positive association occurred in a similar percentage of undergraduate courses for allied health students and science students (72%) and courses for dental and medical students (82%), who are predominantly postgraduate students. Eleven studies reported the use of lecture recordings with a positive association between lecture attendance and academic outcomes being reported for 11 of the 16 courses (69%). From 16 studies/courses not reporting the availability of lecture recordings, 13 did show (82%) a positive association, and three did not show (18%) an association between lecture attendance and academic outcomes. In conclusion, as most studies show a positive relationship between lecture attendance and academic outcomes, it seems reasonable to continue to provide face-to-face lectures, and encourage students to attend. To date, there is no definitive evidence that the availability of lecture recordings alters the positive relationship between lecture attendance and academic outcomes.

Abstract Background: Most studies, in the absence and presence of lecture recordings, have shown that there is an association between lecture attendance and academic performance for students of the biological sciences, but it is not known whether this occurs when lecture attendance is low. The effect of accessing lecture recordings on academic outcomes is not clear. The aims were (i) to determine any association between lecture attendance and academic outcomes for students who had access to lecture recordings, (ii) to describe how students use lecture recordings, and (iii) to determine any association between accessing lecture recordings and academic outcomes.Methods: During the lecture in week 1 and workshops in week 2, written consent was sought from the students to undertake the study. Lecture attendance and lecture recording access were measured. To determine whether there was an association between attending lectures or accessing lecture recordings and academic outcomes, Pearson’s correlation coefficients were calculated.Results: Consent was forthcoming from 48 students (75%). The main findings in this study of lecture attendance and lecture recording access in second year undergraduate optometry students in a pharmacology course were (i) lecture attendance was very low (mean, 15%), (ii) there was no association between lecture attendance and academic outcomes, (iii) early in semester, most of the accessing of lecture recordings was shortly after the lecture was presented, whereas later in the semester, most of the accessing was prior to the examination, and (iv) there was a significant weak association between accessing lecture recordings and academic outcomes.Conclusions: It is possible that as lecture attendance decreases and students become more reliant on lecture recordings, the positive association between lecture attendance and academic outcomes is lost, and a positive association between accessing lecture recordings and academic outcomes emerges.

Recent progress in the electron-mirror microscopy (EMM), e.g., an improvement of its resolving power together with an increase of the magnification makes it useful for investigating the ferroelectric domain physics. English has recently observed the domain texture in the surface layer of BaTiO3. The present authors ) have developed a theory by which one can evaluate small one-dimensional electric fields and/or topographic step heights in the crystal surfaces from their EMM pictures. This theory was applied to a quantitative study of the surface pattern of BaTiO3).

Preliminary Study

Purpose The purpose of this study was to investigate executive function measures as they relate to clinical and academic performance outcomes of graduate speech-language pathology students. Method An observational design incorporating correlations and stepwise multiple regressions was used to determine the strength of the relationships between clinical outcomes that occurred at various time points throughout the graduate program (clinical coursework grades throughout the program and case study paper scores at the end of the program), academic outcomes (graduate grade point average and Praxis II exam in speech-language pathology scores), and executive function (EF) scores (EF assessment scores, self-reported EF scores). Participants were 37 students (36 women, M age = 24.1) in a master's degree program in speech-language pathology at a southeastern U.S. university during the 2017–2018 academic year. Results Findings of this preliminary study indicated that a limited number of objective EF scores and self-reported EF scores were related to clinical and academic outcomes of graduate speech-language pathology students. Conclusion As results of this preliminary study suggest that EF tests may be related to clinical and academic outcomes, future research can move to study the potential role of EF measures in the graduate admissions process in clinical graduate programs such as speech-language pathology.

Abstract Complex trauma resulting from chronic maltreatment and prenatal alcohol exposure can significantly affect child development and academic outcomes. Children with histories of maltreatment and those with prenatal alcohol exposure exhibit remarkably similar central nervous system impairments. In this article, I will review the effects of each on the brain and discuss clinical implications for these populations of children.
