Using commonly-available technologies to create online multimedia lessons through the application of the Cognitive Theory of Multimedia Learning.

Principles derived from the Cognitive Theory of Multimedia Learning (CTML; Mayer in: Multimedia learning, Cambridge University Press, Cambridge, 2021) provide valuable guidance for enlisting commonly-available technologies to create effective online multimedia lessons. Specifically, CTML can guide instructional designers on the use of slide-sharing programs to create concise, narrated animation segments; the use of survey programs to interpolate questions and prompts between these segments to facilitate generative learning activities; and the use of video-sharing sites to provide learners with control over relatively superficial aspects of instruction. The application of CTML to the design of online multimedia lessons raises a number of theoretical and practical questions, including the need to better understand the relationship between working memory capacity and working memory duration, the importance of retrieval as a learning process, and the relative impact of selection and organization processes on learning.

Age-Related Changes on the Effects of Job Characteristics on Job Satisfaction: A Longitudinal Analysis.

Older adults constitute an increasingly large share of the workforce. Older workers often contribute positively to organizational outcomes through characteristics such as deep organizational knowledge and long-standing client relationships. Thus, it is important to understand how to maintain or increase older workers' job satisfaction, a variable that has been linked to positive work outcomes. In this study, several hypotheses regarding job satisfaction and age were derived from Carstensen's socioemotional selectivity theory and were tested using longitudinal analysis of a cross-sequential sample. Supporting socioemotional selectivity theory, results showed that autonomy became increasingly important to job satisfaction as workers age. Contrary to the theory, annual income also became increasingly important to job satisfaction. We discuss the importance of our findings for theory, research, and practice.

Perceived parental investment in school as a mediator of the relationship between socio-economic indicators and educational outcomes in rural America.

Each year, 1.3 million students fail to graduate, dropping the United States' high school graduation rate to 69%. One of the most salient predictors of high school dropout is socio-economic status (SES), which makes important an improved understanding of the reasons why SES affects educational outcomes. In this study, multilevel mediation models were utilized to examine parental investment in school as a mediator of the relationship between SES and educational outcomes among an ethnically diverse sample of 64,350 7th to 9th grade students from 199 rural communities and towns in the U.S. (50% male, 63% non-Hispanic White). These relationships were assessed at the individual and school district level. Results indicate that parental investment is an important mediator at both levels. Within school districts, 28% of the effect of SES on the expectation to graduate from high school is mediated by perceived parental investment. Between school districts, 60% of the effect of concentrated disadvantage on the district's high school graduation rate and nearly all (87%) of the effect of concentrated disadvantage on the average expectation to graduate from high school among students in the district is mediated by perceived parental investment. Implications for prevention are discussed.

Arousal, working memory, and conscious awareness in contingency learning.

There are wide individual differences in the ability to detect a stimulus contingency embedded in a complex paradigm. The present study used a cognitive masking paradigm to better understand individual differences related to contingency learning. Participants were assessed on measures of electrodermal arousal and on working memory capacity before engaging in the contingency learning task. Contingency awareness was assessed both by trial-by-trial verbal reports obtained during the task and by a short post-task recognition questionnaire. Participants who became aware had fewer non-specific skin conductance responses and tended to score higher on a digit span assessment. Skin conductance level was not significantly lower in the aware group than in the unaware group. These findings are consistent with studies showing that lower arousal and greater cognitive processing capacity facilitate conscious perception of a greater breadth of information within a scene or a task.
