Next generation crosscutting themes: Factors that contribute to students' understandings of size and scale

This study examined the degree to which individual differences in students' (N = 232) concepts of size and scale are explained by factors such as students' innate sense of number, out‐of‐school science experiences, exposure to size and scale instruction, gender identities, and racial/ethnic identities. There is increasing emphasis being placed on the use of crosscutting concepts to promote deep learning in science. A multiple linear regression indicated students' racial/ethnic identities, experiences with scale outside of school, and exposure to size and scale instruction significantly added to the prediction model. Results from this study can both inform the movement toward incorporating crosscutting concepts into pedagogy as well as inform educators, administrators, and other stakeholders of the factors that may shape students' understanding of the cross‐cutting concept of scale, proportion, and quantity.     

Online Political Discourse: Exploring Differences in Effects of Civil and Uncivil Disagreement in News Website Comments

An experiment (N = 272) demonstrated that disagreement—either civil or uncivil—may have a chilling effect on the public discourse vital to a deliberative democracy. Both forms of disagreement—in comments posted on a news story about abortion—caused negative emotion and aggressive intentions. However, only uncivil disagreement led people to respond back uncivilly and indirectly led to greater intention to participate politically, if it aroused aggressive feelings. Findings support extending face and politeness theories to the computer-mediated space of online commenting. Results are discussed in relation to the impact on the public discourse.     

Construct Validation of the Self-Efficacy Teaching and Knowledge Instrument for Science Teachers-Revised (SETAKIST-R): Lessons Learned

Described herein is the academic lineage and independent validation of the Self-Efficacy Teaching and Knowledge Instrument for Science Teachers-Revised (SETAKIST-R). Data from 334 K-12 science teachers were analyzed using Partial Credit Rasch models. Principal components analysis on the person-item residuals suggest two latent dimensions: Knowledge and Teaching Self-Efficacies. Item-fit statistics were used to select items for each subscale. Person and item separation (reliability) indices were quite low, and we noted disordered response patterns on the person-item maps that revealed problems with item content and/or scaling for both subscales. These issues include the presence of: verbal negatives, ambiguous modifiers, counter-intuitive scaling, and an “undecided/uncertain” option. The SETAKIST-R, in its current form, cannot be recommended as a measure of science teacher self-efficacy.     

Language, social behavior, and the quality of friendships in adolescents with and without a history of specific language impairment

Language is drawn on extensively in friendships but has received scant attention in the developmental literature. This study compared friendship quality in 16-year-old adolescents with and without specific language impairment (SLI), testing the extent it is predicted by individual differences in social behaviors and language ability. Participants were 120 adolescents with SLI and 118 typically developing (TD) adolescents. After considering the effects of nonverbal IQ and prosocial and difficult behavior, language measures were found to be associated with friendship quality. The TD participants enjoyed normal friendships, whereas the participants with SLI were more likely to exhibit poorer quality (although 60% experienced good quality of friendships). Longitudinal analyses identified early language difficulties as predictive of poorer friendship quality in adolescence.     

A person-oriented approach to understanding dimensions of parenting in low-income mothers

The purpose of this study was to examine parenting types in a low-income sample from a person-oriented approach. Data were used from a public use data set from the Early Head Start Research and Evaluation Project (EHSREP) along with new extant ratings of parenting behavior from the EHSREP archive of videotaped parent–child observations. Parenting behavior indicators were examined using latent class analysis as a grouping strategy across three time points to characterize this sample of 2631 Early Head Start mothers. Three latent classes of mothers were identified at 14, 24, and 36 months: developmentally supportive (the largest group in this sample), unsupportive, and negative. Predictors of parenting types were also examined and parenting types were linked to child outcomes. The results of these analyses show common characteristics of these distinct types of parents likely to be in Early Head Start programs and may help programs identify which families would most benefit from services to help them increase behaviors to promote their young children's early development.     

Exploring early childhood preservice teachers’ mathematics anxiety and mathematics efficacy beliefs

Early childhood preservice teachers participated in a qualitative multiple case study to explore and examine the effectiveness of reform-based constructivist methods used in a mathematics methods course to change their mathematics anxiety, mathematics self-efficacy, and mathematics teachers’ efficacy beliefs. Findings indicated that instructor’s use of a variety of reform-based strategies to teach and model concepts were effective in reducing their mathematics anxiety and improving their mathematics self-efficacy and mathematics teaching efficacy beliefs. Based on these findings, it is recommended that mathematics methods course instructors use reform-based constructivist methods in their courses as outlined by the NCTM’s (2014) principles. Teacher educators must also consider carefully their attitudes and disposition toward mathematics along with the type of classroom and learning environment they establish in mathematics methods courses. They must emphasize conceptual understanding during mathematics methods courses, understand the connection between preservice teachers’ mathematics anxiety and mathematics efficacy beliefs, and integrate field experiences as well as peer teaching opportunities into mathematics methods courses.     

Challenging Traditional Sex Role Stereotypes in Careers Education Broadcasts: the reactions of young secondary school pupils

The ways in which television presents images of male and female roles to the young have recently been subjected to much scrutiny and criticism. Educational television has the scope to contribute to changes in the balance of sex role portrayal but little is known of the likely effects of modifications. This paper reports an experimental study of young secondary school pupils’ reactions to careers education materials in which men and women are shown in occupations traditionally associated with the opposite sex. Children viewing counter‐stereotyped programmes are found to be no less stereotyped in their career beliefs than peers viewing a ‘traditional’ programme or controls who view no programme. The results are discussed in terms of the resilience of sex role and career beliefs in early adolescence and it is concluded that intervention attempts will need to be more extensive and more protracted.     

Investigating English reading comprehension growth in adolescent language minority learners: some insights from the simple view

The development of reading skills in language minority (LM) learners, particularly during the middle school years, remains unclear despite the increasing need for educators to serve this rapidly growing population. In this study, the English reading comprehension growth of middle school LM learners was investigated using a longitudinal design and the simple view of reading as a theoretical framework. Students were assessed at four time points between fifth and seventh grades on standardized measures of listening comprehension, word reading, and reading comprehension. Individual growth modeling revealed that both listening comprehension and word reading assessed in fifth grade predicted the elevation of students’ developmental trajectories in reading comprehension. However, neither skill predicted students’ growth in reading comprehension, and there was no significant variation across children in growth rates, indicating that students in seventh grade remained on a trajectory established in fifth grade. The implications of the slowing rate of reading comprehension development during the middle school years are discussed.     

Personal digital assistant-based drug information sources: potential to improve medication safety.

OBJECTIVES: This study compared the potential for personal digital assistant (PDA)-based drug information sources to minimize potential medication errors dependent on accurate and complete drug information at the point of care. METHODS: A quality and safety framework for drug information resources was developed to evaluate 11 PDA-based drug information sources. Three drug information sources met the criteria of the framework: Eprocrates Rx Pro, Lexi-Drugs, and mobileMICROMEDEX. Medication error types related to drug information at the point of care were then determined. Forty-seven questions were developed to test the potential of the sources to prevent these error types. Pharmacists and physician experts from Creighton University created these questions based on the most common types of questions asked by primary care providers. Three physicians evaluated the drug information sources, rating the source for each question: 1=no information available, 2=some information available, or 3 = adequate amount of information available. RESULTS: The mean ratings for the drug information sources were: 2.0 (Eprocrates Rx Pro), 2.5 (Lexi-Drugs), and 2.03 (mobileMICROMEDEX). Lexi-Drugs was significantly better (mobileMICROMEDEX t test; P=0.05; Eprocrates Rx Pro t test; P=0.01). CONCLUSION: Lexi-Drugs was found to be the most specific and complete PDA resource available to optimize medication safety by reducing potential errors associated with drug information. No resource was sufficient to address the patient safety information needs for all cases.
