Crosscutting concepts and achievement: Is a sense of size and scale related to achievement in science and mathematics?

This study examined the relationship between students' (N = 229) concepts of size and scale and students' achievement in science and mathematics over a 3-year period. Size and scale are considered one of the big ideas in science that permeates disparate science and mathematics content areas, yet little is known about the relationship between students' conceptualization of size and scale and students' achievement in science and mathematics. The study used a modified panel longitudinal design to follow the same class of students over a 3-year period. The goal was to explore whether understandings of size and scale are related to achievement in mathematics and science. Results indicated a strong positive significant relationship existed between students' understanding of size and scale and students' science achievement in grades 5 and 8. There was a positive significant relationship between students' concepts of size and scale and students' mathematics achievement in grades 5, 6, 7, and 8. An examination of the relationships is included as well as a discussion of the integration of crosscutting concepts into science and mathematics instruction as a way to support deep learning.     

Early number and arithmetic performance of Ecuadorian 4-5-year-olds

This study aimed at (a) constructing a reliable and valid test to assess Ecuadorian 4–5-year olds’ number and arithmetic skills; (b) providing empirical data on Ecuadorian 4–5-year olds’ number and arithmetic skills; and (c) confronting these children’s actual performances with the performances expected by national experts in this domain. We administered the Test of Early Number and Arithmetic (TENA), developed on the basis of the Ecuadorian mathematics standards to 86 Preschoolers and 127 Kindergartners and asked 10 experts to evaluate TENA’s validity and predict children’s performances on it. Results supported the overall reliability and validity of the TENA. Furthermore, we observed differences in number and arithmetic competencies between and within Preschoolers and Kindergartners, but not between boys and girls. Finally, experts overestimated children’s performances on the test. The scientific and practical implications of these results are discussed.     

Reliability of a Cryoscopic Micro-Osmometer Using 15-µL Plasma Samples to Measure Hydration Status in Varied Environmental Conditions

Measurement of plasma osmolality (P_osm) remains popular for assessing hydration status in exercise science. However, a controlled reliability assessment of micro-osmometry using small sample volumes to measure P_osm remains to be performed. This study aimed to examine the reliability of a cryoscopic micro-osmometer requiring 15-μL samples across varied environmental conditions. Thirteen young adults (26.4 ± 5.7 years) completed a 20-min steady-state cycling protocol on separate occasions in cool/dry conditions and hot/humid conditions. P_osm was assessed using fingertip capillary samples taken in duplication prior to and following 20-min acclimatization and recovery periods around the cycling bout. Absolute (typical error of measurement = .62–.83 mOsmol·kg^–1; coefficient of variation = .9% to 1.3%) and relative (intraclass correlation coefficient = .60–.85) reliability of this approach were supported. These findings suggest micro-osmometry requiring small plasma samples (15 μL) can be reliably used by practitioners to assess longitudinal changes and cross-sectional hydration status in varied environmental conditions.     

The continuing bonds of US expatriates living in Egypt

This study used the continuing bonds model, which describes the process of loss and mourning, to build a theory about the acculturation process of US expatriates. We examined six case studies of US expatriates permanently residing and working in Egypt. Participants were interviewed about the loss of their US culture and their cultural experiences in Egypt. All participants acknowledged losing aspects of their US culture, and kept continuing bonds with it, but these bonds took different forms depending on the way they responded to their loss and the way they negotiated the influences of both host and native cultures. We present three of these case studies in this paper due to space limitations. One participant believed that his continuing bonds might be imagined or outdated and used religion to avoid the influences of both US and Egyptian cultures in his life. Another participant used his continuing bonds to inspire marginalized Egyptians and refugees. The third participant used his continuing bonds to isolate himself from the Egyptian culture and lead an exclusive American lifestyle. External factors such as political climate of host country, family members, privilege, circumstances of coming to Egypt, and age influenced the mourning process.     

Cross-Cultural Perspectives on Intercultural Communication Competence

This study examined the process of developing intercultural communication competence (ICC) with particular attention to cross-cultural differences in communication patterns. A qualitative approach involving 40 interviews with Americans living in Sweden and Swedes living in the US was employed in order to gain a nuanced, in-depth, and contextual understanding of how immigrants and expatriates experience the process. Several differences in verbal and nonverbal communication patterns between the two cultures emerged. The findings provide insights into how ICC is developed differently across cultures, as well as how the cognitive, affective, and behavioral components of ICC are interrelated and influenced by culture-specific aspects.     

Safety and security in schools in KwaZulu-Natal

This article is based on research conducted on the topic: Safety and security in schools: The case of KwaZulu-Natal. For the research project a purposive sample consisting of secondary school learners, teachers, school governing body chairpersons and principals were selected from the rural and township schools used in this study to explore the views of respondents about the state of safety and security in their school environments. The research was grounded in the social interpretive tradition, using an ethnographic research design, with one-on-one and focus group interviews. Data were analysed using critical discourse analysis to construct the main theme: namely, safety within schools. The findings indicated that learners and teachers are not safe in their schools. Lack of safety and security is characterised by the vulnerability of schools with regard to issues such as fighting, violent murders, sexual harassment, stabbings, the use of derogatory language and threats. It is argued that there is an urgent need to address the concerns of the participants.     

Epistemic beliefs: Setting the standards for self-regulated learning

Relations were examined between epistemic beliefs, achievement goals, learning strategies, and achievement. We sought to empirically test Muis’ [Muis, K. R. (2007). The role of epistemic beliefs in self-regulated learning. Educational Psychologist, 42, 173–190] hypothesis that epistemic beliefs influence processes of self-regulated learning via the standards students set for learning once goals are produced. Two hundred one undergraduate students from an educational psychology course completed questionnaires designed to measure the various constructs. Students’ final grades were also collected at the end of the semester. Students’ recollections of course tasks revealed that their epistemic beliefs are activated during learning. Results from structural equation modeling revealed epistemic beliefs influenced the types of achievement goals students adopted, which subsequently influenced the types of learning strategies they used in their education course, and their achievement. Moreover, achievement goals mediated relations between epistemic beliefs and learning strategies, and learning strategies mediated relations between achievement goals and achievement.     

Within-year oral reading fluency with CBM: a comparison of models

This study examined the type of growth model that best fit within-year growth in oral reading fluency and between-student differences in growth. Participants were 2,465 students in grades 3–5. Hierarchical linear modeling (HLM) analyses modeled curriculum-based measurement (CBM) oral reading fluency benchmark measures in fall, winter, and spring with grade level and student characteristics (including special education and Limited English Proficiency status) as covariates. Results indicated that a discontinuous growth model fit the data better than a linear growth model, with greater growth in the fall than in the spring. Oral reading fluency growth rates also differed by grade and student characteristics. Implications for school practice and research are discussed.
