Observations of the contemporary news media environment often revolve around the topics of ideological polarization and blurred boundaries between mass and interpersonal communication. This study explores these topics through a focus on the association between ideologically oriented online news use, commenting on online news, and political participation. We hypothesize that both ideological online news use generally and proattitudinal online news use are positively related to political participation and that online news commenting creates “differential gains” by augmenting these relationships. Yet we also hypothesize that counterattitudinal online news use is negatively related to political participation and that online news commenting creates “differential losses” by exacerbating this relationship. Analyses of two independently collected and nationally representative surveys found that frequent ideological online news use, proattitudinal online news use, and commenting are all positively related to political participation. We found no evidence for differential gains as a result of online commenting but only for differential losses—counterattitudinal online news use interacts with commenting to create a negative relationship with political participation. 相似文献

This study seeks to discover whether handball goalkeepers employ a general anticipatory strategy when facing long distance throws and the effect of uncertainty on these strategies. Seven goalkeepers and four throwers took part. We used a force platform to analyse the goalkeeper's movements on the basis of reaction forces and two video cameras synchronised at 500 Hz to film the throw using 3D video techniques. The goalkeepers initiated their movement towards the side of the throw 193 ± 67 ms before the release of the ball and when the uncertainty was reduced the time increased to 349 ± 71 ms. The kinematics analysis of their centre of mass indicated that there was an anticipatory strategy of movement with certain modifications when there was greater uncertainty. All the average scores referring to velocity and lateral movement of the goalkeeper's centre of mass are significantly greater than those recorded for the experimental situation with bigger uncertainty. The methodology used has enabled us to tackle the study of anticipation from an analysis of the movement used by goalkeepers to save the ball. 相似文献

Students enter college chemistry courses with different sources of motivation, appropriate or inappropriate assumptions about
their probability of success and how to study. This study is theoretically aligned with self-regulated learning research.
Clearly, academic performance is closely related to student motivational beliefs and learning strategies. This study investigated
the motivational beliefs and learning strategies of 2 years of college students in the second semester of organic chemistry.
Responses to the Motivational Beliefs and Learning Strategies Questionnaire indicated that student self-efficacy was highly
correlated with academic performance (semester grades). Gender differences were quite pronounced. Male academic performance
was associated with intrinsic motivation as well as the importance placed on the learning task. Test anxiety was negatively
associated with male grades. Extrinsic motivation was negatively correlated with female grades. Responses to students’ sense
of control over learning, the value of the learning task, and self-efficacy were significantly higher for males compared to
females. Faculty who attend to these different patterns may influence beliefs as well as learning strategies. Correcting erroneous
assumptions about how to learn chemistry may help students shift both their attitudes and their learning practices. The notable
gender difference suggests that female chemistry students may especially profit from focused faculty intervention. 相似文献

ABSTRACTReading is a tool that promotes the learning of science across schooling. Scientific texts are conceptually and linguistically complex, especially for students from low-income contexts because they have neither the experience with the language nor the literacy skills to face the challenges of scientific knowledge. This study used a mix method approach to compare the cognitive scaffolding practiced by teachers during science reading activities in high- and low-performing schools. Three teachers and 141 fourth grade students from low socioeconomic background schools participated in 48 class sessions. Classes were video-recorded and transcribed. The data were analyzed using Sanchez’ Pedagogic Practice Analysis System. The results show that teachers from both types of schools continuously use reading as a tool for learning. The effective teacher uses reading with non-invasive scaffolding and varied verbal participation to elaborate knowledge, promoting literal and inferential comprehension and more opportunities for the students to construct knowledge. By contrast, less effective teachers use reading with invasive scaffolding and little verbal participation of the students to consolidate knowledge, promoting mainly literal comprehension. This study shed light on different approaches teachers use to foster reading comprehension for science learning. 相似文献

Although the research literature regarding language growth trajectories is burgeoning, the shape and direction of English Language Learners' (ELLs) language growth trajectories are largely not known. This study used growth curve modeling to determine the shape of ELLs' language growth trajectories across 12,248 oral narrative language samples (6,516 Spanish; 5,732 English) produced by 1,723 ELLs during the first 3 years of formal schooling (M age at first observation = 5 years 7 months). Results indicated distinct trajectories of language growth over time for each language differentially impacted by summer vacation and gender, significant intra‐ and interindividual differences in initial status and growth rates across both languages, and language‐specific relations between language growth and initial status. Implications of ELLs' language growth are discussed. 相似文献

FOR THE GOOD OF OTHERS: CENSORSHIP AND THE THIRD-PERSON EFFECT 总被引：2，自引：0，他引：2

The third person effect hypothesis, which states that individualsexposed to a mass media messaage will expect the communicationto have a greater effect on others than on themselves, may helpto explain the growing trend in support of media censorship.It is suggested here that overestimating the effect of mediaon others may play an important role in the forces underlyinga willingness to restrict various types of communication. Toexamine this relationship, this study focused on the discrepancybetween perceived media effects on others and self, and itsrelation to pro-censorship attitudes within three major topics:the media in general, violence on television, and pornography.The results of this study support the existence of the third-personeffect in mass communication. The findings also indicate thatas the gap between perceived firstand third-person effects increases,individuals are more likely to manifest pro-censorship attitudes.This relationship remained for all three topics even when avariety of potentially confounding demographic, media use, andattitudinal variables were controlled. The data also suggestthat for pornography the effects gap is related to a willingnessto act in favor of censoring. 相似文献

ABSTRACTThe centrality of social relationship for older adults living in prison cannot be underestimated. While previous studies have investigated the loss of social functioning among older prisoners, there is no known information pertaining to how engagement is experienced among this vulnerable group. This grounded study purports to describe the process by which engagement is experienced among a select group of incarcerated Filipino elderly. Strauss and Corbin’s Grounded Theory design was utilized. A total of 25 incarcerated Filipino elderly in the largest penitentiary in the country were purposively chosen to participate in semi-structured interviews. Field texts were subjected to thematic analysis involving open, axial, and selective coding. Finally, themes were validated via member checking procedure. Interestingly, the study afforded the development of de Guzman, Herrera, Hernando, Hipe, and Valdez Zipper of Engagement Theory among incarcerated elderly. Interestingly, three phases relative to engagement emerged, namely: Initiating, Connecting, and Enabling. Primarily, the Initiating phase involves feelings of fear and nervousness as the incarcerated elderly familiarize themselves with the prison environment. The Connecting phase typifies recognition of the benefits of engagement leading to voluntary participation in activities. Finally, in the Enabling phase, inmates empower themselves and others to grow as they fully acquire the sense of engagement. Gerontological education and research implications are discussed. 相似文献
