Objective: Decreasing participation in intervention research among college students has implications for the external validity of behavioral intervention research. We describe recruitment and retention strategies used to promote participation in intervention research across a series of four randomized experiments. Method: We report the recruitment…

In online courses, much of the course communication occurs in public spaces. In synchronous courses, the video and audio channels represent a shared space, and although private chat messages are possible, they may not be substantial or frequent. In asynchronous courses, discussion boards are the allocated space for communication. In these…

Reversing the trend of US STEM graduation rates lagging other industrialized nations requires that we look at the entire pipeline of potential STEM students, including the vast number that start their journeys in remedial math classrooms in two-year colleges. Most research to date has focused on either Learning Support (LS) success or STEM…

Dynamic structural equation modeling (DSEM) is a useful technique for analyzing intensive longitudinal data. A challenge of applying DSEM is the missing data problem. The impact of missing data on DSEM, especially on widely applied DSEM such as the two-level vector autoregressive (VAR) cross-lagged models, however, is understudied. To fill the…

This study investigates the relationship between academic procrastination, self-control, time management, and academic self-efficacy among vocational college students. Grounded in self-control theory, the study utilized convenience sampling to conduct an online survey of 994 students from vocational colleges in Henan Province, China. Descriptive…

This qualitative exploratory study investigated the selection and change of majors for nine HBCU (Historically Black Colleges and Universities) students. The study included individual structured interviews that provided data that answered the following research questions: 1) what factors influenced the initial selection of major, and 2) what…

The problem this qualitative case study addressed is how poor online teacher communication has resulted in students enrolled in full-time virtual schools underperforming academically with assignment completion. The purpose of this study was to explore teachers' perceptions of how their online communication strategies contribute to the timeliness…

Research Findings: This study investigated the sequential mediating effects of parental material investment (MI) and time investment (TI) upon the correlation between family socioeconomic status (SES) and toddlers' development (TD). Data derived from a 2016 data set, including a sample of 1,316 toddlers based in 117 villages across 22 counties…

Smartphone multitasking is prevalent in university classrooms, yet the nature and characteristics of this behavior have not been sufficiently understood. This empirical study explores in-class smartphone multitasking behaviors using diverse research approaches to achieve a more authentic and holistic understanding of this pervasive behavior.…

Longitudinal studies provide developmental science with invaluable information about how variables and the associations between variables change across time, but typically give limited attention to the length of time over which that change occurs. The present study re-analyzed data from previously published meta-analyses of longitudinal data…

Higher numeracy is associated with better comprehension and use of numeric information as well as reduced susceptibility to some decision biases. We extended this line of work by showing that increased numeracy predicted probability maximizing (versus matching) as well as a better appreciation of large sample sizes. At the same time, we replicated…

This article explores bells, and objects in general, from a philosophical perspective. More specifically, it explores the way objects orient our being, but only partially as aspects of things always remain withdrawn from access. Through an exploration of the elemental forms of bells, this article positions object exploration as a wholly spiritual…

This large-scale study characterizes the algebraic learning of a cohort of nearly 800 French students during the last year of middle school (9th grade, 14-15 years old) and examines their evolution in relation to the composition of the classes to which the students belong. Based on the Anthropological Theory of the Didactic (ATD), the study is…

Successful language comprehension requires the rapid deployment of working memory resources alongside the capacity to predict upcoming linguistic input. While previous research views these as competing factors, this dissertation explores a unified theory of processing complexity and evaluates the interaction between memory and prediction. The…

Within the past two decades there has been an increased amount of interest in human-centered information retrieval research beyond the traditional system-focused view embodied by Cranfield- and TREC-style evaluation. From blending search and recommender systems to work on search as learning, the limits of conventional search engines' focus on…
