Starting up or starting over: the role of intentions to increase and maintain the behavior of exercise initiates

Across various social cognitive theories, behavioral intention is broadly argued to be the most proximal and important predictor of behavior (Ajzen, 1991; Gibbons, Gerrard, Blanton, & Russell, 1998; Rogers, 1983). It seems probable that an intention to increase behavior might be differentially determined from an intention to maintain behavior. Thus, the purpose of the current study was to examine (1) the change in two types of behavioral intention over time and (2) the relationship between intention and the social-cognitive factor mental imagery. Behavioral intention, exercise imagery, and observed exercise behavior was measured in 68 exercise initiates participating in a 12-week exercise program. Results revealed that behavioral intention to increase exercise behavior decreased over the exercise program, whereas intentions to maintain exercise behavior increased. Appearance and technique imagery were found to be significant predictors of intention to increase behavior during the first 6 weeks of the program, and only appearance imagery predicted intention to maintain exercise behavior during the last 6 weeks. These findings suggest that the two types of behavioral intention are distinguishable and may be useful targets for exercise behavior interventions.     

Consequences of "minimal" group affiliations in children

Three experiments (total N=140) tested the hypothesis that 5-year-old children's membership in randomly assigned "minimal" groups would be sufficient to induce intergroup bias. Children were randomly assigned to groups and engaged in tasks involving judgments of unfamiliar in-group or out-group children. Despite an absence of information regarding the relative status of groups or any competitive context, in-group preferences were observed on explicit and implicit measures of attitude and resource allocation (Experiment 1), behavioral attribution, and expectations of reciprocity, with preferences persisting when groups were not described via a noun label (Experiment 2). In addition, children systematically distorted incoming information by preferentially encoding positive information about in-group members (Experiment 3). Implications for the developmental origins of intergroup bias are discussed.     

Children's word structure knowledge: Implications for decoding and spelling instruction

Research has shown that not all children internalize the structure of English orthography as they learn to decode and spell. In fact, many children have difficulty mastering these two skills. In this paper, the relevance of word structure knowledge to decoding and spelling instruction and performance is discussed. It was anticipated that explicit, discussion oriented, and direct decoding instruction based on word origin and structure would result in improved reading and spelling performance. During the instruction, students compared and contrasted letter-sound correspondences, syllable patterns, and morpheme patterns in English words of Anglo-Saxon, Romance, and Greek origin. Upper elementary grade students receiving the decoding instruction made significant gains in word structure knowledge and in decoding and spelling achievement.     

Television Literacy Curriculum in Action: a long‐term study

A major concern in the area of television's effect on children has been how children interpret both the content and form of the medium. As a form of representation, television has its own code. Messages are transmitted by manipulating this code. The last decade has seen a growth of interest in ways of combating the influence television has on children by increasing their awareness and understanding of the conventions of the medium. The research described here is a media literacy project that takes children ‘behind the scenes’ of television's ‘magic’ by providing them with the opportunity of producing a programme for community access cable television. This was accomplished by having two groups of grade five children experience a 10‐week media literacy curriculum. Following the curriculum phase, one group ‘produced’ a programme for telecast at the local cable studio. Pre‐, post‐, and long‐term media literacy tests were administered to the two groups and a control group. Results reveal that not only did the groups who had experienced the media literacy curriculum perform significantly better on the test, but also that their scores improved significantly between post‐and long‐term testing. In conclusion, the media literacy curriculum led to significant increases in understanding of media‐related concepts.     

Research‐capacity building,professional learning and the social practices of educational research

There have been numerous attempts in the past few years within education research—and social science research more generally—to alter the character of research practice(s). In particular, there has been a systematic effort to address perceived shortcomings in research practice through a series of ‘research‐capacity building’ initiatives, aimed at the restructuring of professional learning. In this article the authors explore empirically the ways in which different modes of professional learning are implicated in the social practices of education research. These considerations lead to the conclusion that the currently dominant approaches to research‐capacity building are based on an underestimation of the difficulties in influencing the professional learning of educational researchers significantly and, thereby, changing the practices of educational research. More realistic expectations of these forms of research‐capacity building, in turn, suggest the need to develop alternative approaches that acknowledge the exigencies of the current social organisation of educational research more fully.

The differential effects of preschool: Evidence from Virginia

This study investigated the differential and persistent effects of a state-funded pre-K program, the Virginia Preschool Initiative (VPI). We analyzed data from a cohort of over 60,000 students nested in approximately 1000 schools from the beginning of kindergarten to the end of first grade using two-level hierarchical logistic regression models. While controlling for student- and school-level variables, we found that attending a VPI-funded program was beneficially associated with a lower likelihood of repeating kindergarten and improved probabilities of meeting or exceeding minimum literacy competencies. The benefits of attending pre-K were greatest upon kindergarten entry and persisted until the end of the first grade for Hispanic and Black students, as well as for students with disabilities, despite VPI-funded program attendees going to schools with higher concentrations of poverty.     

Gifted native American students: Underperforming,under‐identified,and overlooked

There has been limited focus among researchers on the nature and needs of gifted Native American students in the past 30 years, and the work that has been done frequently generalizes findings across Native American cultures. This article reviews recent literature on Native American youth and on gifted Native American students; examines the current condition of education in the Diné (Navajo) Nation through a sociocultural motivation lens and based on work with one tribal community on this reservation; calls researchers and educators to action and to recognize that, as with all ethnic groups, many individual cultures exist within Native American populations; and offers suggestions for education personnel. © 2012 Wiley Periodicals, Inc.     

Can dynamic visualizations improve middle school students' understanding of energy in photosynthesis?

Dynamic visualizations have the potential to make abstract scientific phenomena more accessible and visible to students, but they can also be confusing and difficult to comprehend. This research investigates how dynamic visualizations, compared to static illustrations, can support middle school students in developing an integrated understanding of energy in photosynthesis. Two hundred 7th‐grade students were randomly assigned to either a dynamic or a static condition and completed a web‐based inquiry unit that encourages students to make connections among energy concepts in photosynthesis. While working on the inquiry unit, students in the dynamic condition interacted with a dynamic visualization of energy transformation, whereas students in the static condition interacted with a series of static illustrations of the same concept. The results showed that students in both conditions added new, scientific ideas about energy transformation and developed a more coherent understanding of energy in photosynthesis. However, when comparing the two conditions, we found a significant advantage of dynamic visualization over static illustrations. Students in the dynamic condition were significantly more successful in articulating the process of energy transformation in the context of chemical reactions during photosynthesis. Students in the dynamic condition also demonstrated a more integrated understanding of energy in photosynthesis by linking their ideas about energy transformation to other energy ideas and observable phenomena of photosynthesis than those students in the static condition. This study, consistent with other research, shows that dynamic visualizations can more effectively improve students' understanding of abstract concepts of molecular processes than static illustrations. The results of this study also suggest that with appropriate instructional support, such as making predictions and distinguishing among ideas, both dynamic visualizations and static illustrations can benefit students. This study underscores the importance of curriculum design in ensuring that dynamic visualizations add value to science instructional materials. © 2012 Wiley Periodicals, Inc.
