金无足赤,大器晚成

当每一年稍纵即逝的时候,我们常常纠结我们理应做过什么,或者我们期望自己做过什么。这些可以是任何一件小事儿,从上课不迟到,保持卧室整洁乃至花多点时间去练习一门乐器,都是可能的。但当我们年少时,我们中的大多数都     

FL-IDE: hypertext for structuring a conceptual design for computer-assisted language learning

A compelling problem for language pedagogues is teaching foreign languages to students so they can retain and use the language skills in real communicative situations. One way to help students learn these skills is to understand and improve current pedagogical approaches to language learning. New technology such as Computer-Assisted Language Learning (CALL) provides pedagogues with rich, multimedia environments for presenting instruction. At the same time, deciding what to present and how to organize the instruction in CALL provides a new challenge. In response to this problem, we discuss preliminary results of a research effort for developing an instructional design environment (IDE) that is uniquely tailored to the needs of developing foreign language instruction. Hypertext features in the IDE software are used to capture and organize into one coherent framework the corpora of theoretical, instructional, and content material that affects foreign language instruction.     

Integrating diversity,equity, and inclusion principles into instruction: Case studies from the University of Florida's Health Science Center Libraries

Librarians at the University of Florida Health Science Center Libraries have begun to intentionally incorporate diversity, equity, and inclusion (DEI) principles into teaching during design, implementation, and evaluation. This article uses four case studies to provide an overview of the librarians' approaches to inclusive teaching (1) an annual workshop for Physical Therapy students on the intersection between DEI, health literacy, and patient education; (2) a librarian-taught one-credit course for public health students, which was revised to create a more inviting syllabus and integrate elements of universal design; (3) an annual project for first year medical students highlighting health disparities and community resources; and (4) piloting the application of critical librarianship principles in library standalone sessions on database searching and reference management. Suggestions are provided for other librarians who are interested in developing a culture of inclusive teaching in their own libraries.     

DVD sales and the R-rating puzzle

In the last decade, attendance at movie theaters has been relatively stagnant, while sales of digital versatile discs (DVDs) have grown dramatically. In this paper, we look at the factors determining sales of individual DVDs in the United States. Using data on new motion pictures released on DVD between 2006 and 2008, we find the demand for new DVDs is price-inelastic and that DVD sales are counter-cyclical. We find that previous box office success has strong positive effects on DVD sales. Production budget also has a positive effect on DVD sales, albeit indirectly through its effect on box office revenues. Critical acclaim has significant positive effects on both box office revenue and DVD sales, but the effect is smaller in regard to DVDs. There is some evidence to suggest that DVD sales are higher for movies with more sexual content and more violent content and lower for movies with more profanity, but these effects are indirect through the changes in the box office of these movies. We find that sales of R-rated DVDs are not as dependent upon critical acclaim as movies of other ratings, and are thus less risky for movie studios to produce. Our findings provide another explanation for the R-rating puzzle.     

The dark side of innovation: Exploring obsolescence and supply chain evolution for sustainment-dominated systems

The problem of technological obsolescence in vendor supplied parts in the new product development process has increased in importance in recent years. This is compounded by both the rapid pace of technological advance and increasingly disintegrated supply chains. This issue has become particularly problematic for products with both a high degree of technology and long life cycles. This exploratory study relates empirical obsolescence findings to theoretically predicted models of innovation diffusion for different product-market conditions. Implications are analyzed for supply chain evolution and obsolescence management.     

Fostering a “head start” in math: observing teachers in early childhood mathematics engagement

ABSTRACT

Studies show that early engagement with mathematics leads to increased math achievement later in life. Yet, early childhood teachers do not regard mathematics as critical to young learners’ development and lack confidence with helping children learn mathematics. Early childhood teacher comfort and engagement with mathematics is a critical element to promoting intentional math instruction. Research was conducted to examine the effects of an innovative professional development program for Head Start preschool teachers with the goal of increasing pedagogical content knowledge and confidence in teaching mathematics. The findings in this article focus on classroom observations that concentrated on teacher engagement with mathematics.     

A Mixed Methods Investigation of Maternal Perspectives on Transition Experiences in Early Care and Education

ABSTRACT

Research Findings: Strong relationships among children, families, and early care and education (ECE) providers are key to quality infant–toddler care. These relationships are shaped during the initial transition period to group care. We used a mixed methods approach to (a) assess maternal perspectives on the transition to group care, (b) explore mothers’ perceptions of factors that made for easy or difficult transitions, and (c) examine associations between maternal and child characteristics and the ease of the transition. Through qualitative interviews, mothers identified factors that played a role in their child’s transition, including the child’s age, the ECE provider’s support, and the number of transitions the child experienced. For mothers, an easy transition was characterized by ease of child adjustment to group care, comfort with nonparental care and returning to work, and being able to exercise some control over the transition. Quantitative analyses revealed that an easy child transition was associated with younger child age, low maternal distress reactions to child distress, and low child social fearfulness. Higher maternal depressive symptoms and maternal distress reactions to child distress were associated with mothers having a difficult transition. Practice or Policy: Implications of the findings for ECE provider training and ECE policy development related to transitions are discussed.
