Description
ABSTRACT The phenomenon of cyberbullying has captured the attention of educators and researchers alike as it has been associated with multiple aversive outcomes including suicide. Young people today have easy access to computer mediated communication (CMC) and frequently use it to harass one another -- a practice that many researchers have equated to cyberbullying. However, there is great disagreement among researchers whether intentional harmful actions carried out by way of CMC constitute cyberbullying, and some authors have argued that "cyber-aggression" is a more accurate term to describe this phenomenon. Disagreement in terms of cyberbullying's definition and methodological inconsistencies including choice of questionnaire items has resulted in highly variable results across cyberbullying studies. Researchers are in agreement however, that cyber and traditional forms of aggression are closely related phenomena, and have suggested that they may be extensions of one another. This research developed a comprehensive set of items to span cyber-aggression's content domain in order to 1) fully address all types of cyber-aggression, and 2) assess the interrelated nature of cyber and traditional aggression. These items were administered to 553 middle school students located in a central Illinois school district. Results from confirmatory factor analyses suggested that cyber-aggression is best conceptualized as integrated with traditional aggression, and that cyber and traditional aggression share two dimensions: direct-verbal and relational aggression. Additionally, results indicated that all forms of aggression are a function of general aggressive tendencies. This research identified two synthesized models combining cyber and traditional aggression into a shared framework that demonstrated excellent fit to the item data.

Description
Recent legislation allowing educational agencies to use Response to Intervention (RTI) in determining whether a child has a specific learning disability, coupled with a focus on large-scale testing and accountability resulted in the increasing use of curriculum based measurement (CBM) as a tool for understanding students' progress towards state standards, particularly in reading through the use of oral reading fluency measures. Extensive evidence of oral reading fluency's predictability of reading comprehension exists, but little research on differential effects across racial, gender, and socioeconomic subgroups is available. This study investigated racial, gender, and socioeconomic bias in DIBELS Oral Reading Fluency (DIBELS ORF) probes predictive and concurrent relationship with MAP reading comprehension scores for African American and Caucasian students. Participants were 834 second through fifth grade students in a school district located in a southeastern US state. The dataset consisted of student fall and spring DIBELS ORF scores and spring MAP reading comprehension scores. Concurrent correlation results between spring DIBELS ORF and MAP reading comprehension scores were moderate to large and statistically significant across all grades and demographic groups; however, correlations between fall DIBELS ORF and MAP reading comprehension scores were generally weak. Stepwise multiple regression analyses were used to examine the best variable, or combination of variables, in predicting MAP reading comprehension scores. Models differed for each grade level; however, spring DIBELS ORF scores were always included, whether alone or in combination with demographic variables, in the best prediction model. Potthoff's procedure was used to simultaneously test for slope and intercept differences among regression equations to determine if DIBELS ORF scores from fall and spring differentially predicted MAP reading comprehension scores across demographic groups. Nine of 24 simultaneous contrasts demonstrated a significant effect; seven were related to race, one was related to gender, and one was related to socioeconomic status. Racial bias in predicting MAP reading comprehension performance from spring DIBELS ORF was found. Differential prediction among gender and SES groups was not consistent indicating little to no practical significance. Results are discussed in the context of practical implications of differential validity, both predictive and concurrent, and potential impact on disproportionality.

Description
The purpose of this study was to investigate the impacts of visual cues and different types of self-explanation prompts on learning, cognitive load and intrinsic motivation, as well as the potential interaction between the two factors in a multimedia environment that was designed to deliver a computer-based lesson about the human cardiovascular system. A total of 126 college students were randomly assigned in equal numbers (N = 21) to one of the six experimental conditions in a 2 X 3 factorial design with visual cueing (visual cues vs. no cues) and type of self-explanation prompts (prediction prompts vs. reflection prompts vs. no prompts) as the between-subjects factors. They completed a pretest, subjective cognitive load questions, intrinsic motivation questions, and a posttest during the course of the experience. A subsample (49 out of 126) of the participants' eye movements were tracked by an eye tracker. The results revealed that (a) participants presented with visually cued animations had significantly higher learning outcome scores than their peers who viewed uncued animations; and (b) cognitive load and intrinsic motivation had different impacts on learning in multimedia due to the moderation effect of visual cueing. There were no other significant findings in terms of learning outcomes, cognitive load, intrinsic motivation, and eye movements. Limitations, implications and future directions are discussed within the framework of cognitive load theory, cognitive theory of multimedia learning and cognitive-affective theory of learning with media.

Description
The purpose of this experimental study was to investigate the effects of textual and visual annotations on Spanish listening comprehension and vocabulary acquisition in the context of an online multimedia listening activity. 95 students who were enrolled in different sections of first year Spanish classes at a community college and a large southwestern university were randomly assigned to one of four versions of an online multimedia listening activity that contained textual and visual annotations of several key words. Students then took a comprehension and vocabulary posttest and a survey to measure cognitive load and general attitudes towards the program. Results indicated that textual annotations had a significant positive effect on listening comprehension and that visual annotations had a significant positive effect on how successful students felt. No statistically significant differences were found for other variables. Participants also reported positive attitudes towards vocabulary annotations and expressed a desire to see more annotations during multimedia listening activities of this type. These findings provide further evidence of the impact that multimedia may have on language acquisition. These findings have implications for multimedia design and for future research. Language listening activities should include a variety of vocabulary annotations that may help students to understand what they hear and to help them learn new vocabulary. Further research is needed outside of the laboratory, in the online and increasingly-mobile language learning environment in order to align the research with the environment in which many students currently study. The incorporation of motivation into multimedia learning theory and cognitive load should be explored, as well as new measures of cognitive load.
