Text density level as a design variable in instructional displays

Presenting narrative text in computer-based instruction (CBI) is more difficult than in print lessons due to limited screen resolution and display area. The present research aimed at achieving a more compatible match between lesson content and the attributes of the presentation media. Subjects received either a print or CBI statistics lesson containing low-density (concise) narrative text, high-density (conventional) text, or the density type they preferred (learner-control). Results showed the low-density lesson to reduce completion time relative to the high-density version, while yielding equivalent achievement. Subjects receiving the lesson in the print mode had shorter completion times and higher achievement than their CBI counterparts. Attitude results showed that CBI was favorably regarded, but perceived as longer and slow-moving than print. Implications of results for designing instructional material in accord with CBI attributes and learner characteristics are discussed.     

Culturally and Linguistically Relevant Readalouds

The teacher readaloud is an instructional tool established in its ability to foster children's language and literacy development. Increasing cultural and linguistic diversity and changing standards place pressure on teachers to provide literacy and language instruction relevant to children's everyday lives and learning. This article presents a framework for conducting culturally and linguistically relevant readalouds within two essential components, talk and text, in terms of developing cultural competence, maintaining high academic expectations, and fostering a critical stance. Particular attention is given to the interactive nature of these readalouds and how they can be used to promote children's active co-construction of textually-based meaning.     

INFLUENCE OF ASCRIBED AND ACHIEVED SOCIAL STATUSES,VALUES, AND REWARDS ON JOB SATISFACTION AMONG COMMUNITY COLLEGE FACULTY

Research on job satisfaction among community college faculty has been largely atheoretical. The present study examined the contribution of four sets of factors to explaining faculty job satisfaction in the community college. According to Kalleberg's (1977) theory of job satisfaction, employee's affective reactions to their jobs are largely determined by ascribed social statuses, achieved social statuses, job values, and job rewards. A random sample was drawn of 371 full‐time faculty from a multi‐campus community college district located in a metropolitan area in the Southwest. Nonresponses and partial responses resulted in an effective sample size of 261. A correlation analysis revealed that institutional age and physical safety job value were significantly, inversely related to job satisfaction and that all job rewards were significantly, positively related to job satisfaction. A simultaneous multiple regression analysis indicated that institutional age was a significant, inverse predictor of job satisfaction and that chronological age, and the good supervision and work itself job rewards were significant, positive predictors of job satisfaction. Of the variation in job satisfaction scores accounted for by all predictors, approximately 5% may be attributed to ascribed and achieved social statuses and to job values, and 48% to job rewards. For faculty in the district we surveyed, the keys to promoting job satisfaction would be to enhance the satisfying aspects of the work itself and good supervision. Programs which afford faculty who are less than satisfied with their jobs opportunities to be “origins” rather than “pawns” may be beneficial.     

The Mediating Effects of Student Engagement on the Relationships Between Academic Disciplines and Learning Outcomes: An Extension of Holland’s Theory

This research examined the relationships among students?? academic majors, levels of engagement, and learning outcomes within the context of Holland??s person?Cenvironment theory of vocational and educational behavior. The study focused on the role of student engagement as a mediating agent in the relationships between academic majors and student learning. Drawing on data from a stratified random sample of 20,000 seniors who participated in the 2008 National Survey of Student Engagement, results revealed that students?? academic majors were significantly related to levels of engagement and learning outcomes. Student engagement was also significantly related to learning outcomes. Students?? academic majors generally were not indirectly related to learning outcomes through levels of engagement. An important exception to this result was found for students in Enterprising environments where indirect relationships among Enterprising disciplines and Enterprising learning outcomes were positive, statistically significant, and substantially larger than the direct relationship.     

Social media campaigns,electoral momentum,and vote shares: evidence from the 2016 Hong Kong Legislative Council election

By studying candidates’ Facebook fan pages and rolling poll data during the Hong Kong Legislative Council election in 2016, this article aims at examining the relationships between candidates’ campaign performance on social media, electoral momentum, and vote shares. We contend that, under specific contextual conditions, social media campaigns could affect candidates’ momentum during the election period, which can in turn affect vote shares. We also examine how the relationships between social media performance and electoral momentum vary according to the candidates’ background characteristics, including age, political affiliation, incumbency status, and scale of the campaign of the political group to which the candidates belong. The results show that candidates’ social media performance can indeed predict vote shares indirectly via the mediation of electoral momentum. The predictive power of social media performance is stronger for pro-democracy candidates, incumbents, and candidates belonging to political groups with larger election campaigns.     

Selected factors associated with achievement of biology preparatory students and their follow-up to higher level biology courses

This study was undertaken to determine whether a biology preparatory course given at an urban community college was helping students to develop the proper skills and background necessary for them to successfully complete follow-up courses in biology. A group of students who enrolled in a biology preparatory course, and subsequently, a follow-up anatomy and physiology or general biology course (experimental group) was compared to a group of students who should have registered for the preparatory course, but who enrolled directly into the anatomy and physiology or general biology course (control group). It was shown that there was no significant difference in their anatomy and physiology or general biology grades. Furthermore, only 16% of the initial group of preparatory students enrolled in and passed a follow-up biology course. Examination of the preparatory group using discriminant analysis ascertained that mathematics score was the principle discriminator between pass/fail groups. A stepwise multiple regression analysis of the variables explaining the preparatory grade showed that mathematics score, reading score, and type of high school degree explained 33% of the variance. Of the students who did pass the preparatory course and enrolled in a follow-up biology class, their preparatory grade was a good predictor of their achievement (measured by follow-up course grade), as determined by multiple regression.
