Selected AbstractsGender Differences in a Comparison of Two Tested Etiological Models of Cigarette Smoking Among Elementary School Students,JOURNAL OF APPLIED SOCIAL PSYCHOLOGY, Issue 8 2007Randall C. Swaim The theory of reasoned action (TRA), theory of planned behavior (TPB), and a revised TPB were evaluated using manifest variable structural equation modeling among 4th - through 6th -grade students for effectiveness in predicting lifetime cigarette use. TRA was an adequate model for female students, but not male students. TPB resulted in improved model fit over TRA for both male and female students, and a revised TPB model improved fit marginally among female students. Tests for differences across gender indicated that the relationship between intention to use and lifetime cigarette use was stronger among female compared to male students. The results indicate that the TPB is an effective model for predicting lifetime cigarette use among late elementary-school-aged children. [source] Parents of Elementary School Students Weigh in on Height, Weight, and Body Mass Index Screening at SchoolJOURNAL OF SCHOOL HEALTH, Issue 10 2006Martha Y. Kubik However, there are little empirical data available to guide decision making about the acceptability and safety of programs. A pilot study was conducted using a quasiexperimental research design. In fall 2004, children in 4 suburban elementary schools (kindergarten to sixth grade) in the St Paul/Minneapolis, MN, metropolitan area completed height/weight screening. The following spring, parents in 2 schools received letters containing height/weight and BMI results. A self-administered post-only survey examined parents' opinions and beliefs regarding school-based BMI screening and parent notification programs (response rate: 790/1133 = 70%). The ,2 test of significance was used to examine differences in program support by treatment condition, child's weight status, and sociodemographic characteristics. Among all parents, 78% believed it was important for schools to assess student's height/weight annually and wanted to receive height, weight, and BMI information yearly. Among parents receiving the letter, 95% read most/all of the letter. Most parents (80%) and children (83%) reported comfort with the information in the letter. Parents of overweight children were more likely to report parental discomfort as well as child discomfort with letter content. There was considerable parental support for school-based BMI screening and parent notification programs. Programs may be a useful overweight prevention tool for children. However, continued attention to how best to support parents and children affected by overweight is required.

Andrade The purpose of this study was to investigate the effect of reading a model written assignment, generating a list of criteria for the assignment, and self-assessing according to a rubric, as well as gender, time spent writing, prior rubric use, and previous achievement on elementary school students' scores for a written assignment (N = 116). Participants were in grades 3 and 4. The treatment involved using a model paper to scaffold the process of generating a list of criteria for an effective story or essay, receiving a written rubric, and using the rubric to self-assess first drafts. The comparison condition involved generating a list of criteria for an effective story or essay, and reviewing first drafts. Findings include a main effect of treatment and of previous achievement on total writing scores, as well as main effects on scores for the individual criteria on the rubric. The results suggest that using a model to generate criteria for an assignment and using a rubric for self-assessment can help elementary school students produce more effective writing. [source] The Stability of Rater Severity in Large-Scale Assessment ProgramsJOURNAL OF EDUCATIONAL MEASUREMENT, Issue 2 2000Peter J. Congdon The purpose of this study was to investigate the stability of rater severity over an extended rating period. Multifaceted Rasch analysis was applied to ratings of 16 raters on writing performances of 8, 285 elementary school students. Each performance was rated by two trained raters over a period of seven rating days. Performances rated on the first day were re-rated at the end of the rating period. Statistically significant differences between raters were found within each day and in all days combined. Daily estimates of the relative severity of individual raters were found to differ significantly from single, on-average estimates for the whole rating period. For 10 raters, severity estimates on the last day were significantly different from estimates on the first day. These fndings cast doubt on the practice of using a single calibration of rater severity as the basis for adjustment of person measures. [source] System thinking skills at the elementary school levelJOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 5 2010Orit Ben-Zvi Assaraf Abstract This study deals with the development of system thinking skills at the elementary school level. It addresses the question of whether elementary school students can deal with complex systems. The sample included 40 4th grade students from one school in a small town in Israel. The students studied an inquiry-based earth systems curriculum that focuses on the hydro-cycle. The program involved lab simulations and experiments, direct interaction with components and processes of the water cycle in the outdoor learning environment and knowledge integration activities. Despite the students' minimal initial system thinking abilities, most of them made significant progress with their ability to analyze the hydrological earth system to its components and processes. As a result, they recognized interconnections between components of a system. Some of the students reached higher system thinking abilities, such as identifying interrelationships among several earth systems and identifying hidden parts of the hydrological system. The direct contact with real phenomena and processes in small scale scenarios enabled these students to create a concrete local water cycle, which could later be expanded into large scale abstract global cycles. The incorporation of outdoor inquiry-based learning with lab inquiry-based activities and knowledge integration assignments contributed to the 4th grade students' capacity to develop basic system thinking abilities at their young age. This suggests that although system thinking is regarded as a high order thinking skill, it can be developed to a certain extent in elementary school. With a proper long-term curriculum, these abilities can serve as the basis for the development of higher stages of system thinking at the junior,high/middle school level. © 2009 Wiley Periodicals, Inc.

Data were combined from two sources: interviews with 20 individuals and an open-ended questionnaire that was administered to 240 students (121 upper elementary school students and 119 middle school students). We observed a wealth of approaches ranging from accounts of energy transfer and transformation to responses identifying specific objects or processes as the cause of changes. The findings also provide evidence that students do not seem to appreciate the transphenomenological and unifying nature of energy. Students' thinking was influenced by various conceptual difficulties that are compounded by traditional science teaching; for instance, students tended to confuse energy with force or electric current. In addition, the comparison between the responses from middle school students and those of elementary school students demonstrates that science teaching and maturation appeared to have a negligible influence on whether students had constructed a coherent energy model, which they could use consistently to account for changes in certain physical systems. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 45: 444,469, 2008 [source] Middle school students' beliefs about matterJOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 5 2005Mary B. Nakhleh The objective of this study was to examine middle school students' developing understanding of the nature of matter and to compare middle school students' ideas to those of elementary schools students, as was done by Nakhleh and Samarapungavan [J Res Sci Teach 36(7):777,805, 1999]. Nine middle school students were interviewed using a scripted, semistructured interview. The interview probed students' understanding of the composition and particulate (atomic/molecular) structure of a variety of material substances; the relationship between particulate structure and macroscopic properties such as fluidity and malleability; as well as understanding of processes such as phase transition and dissolving. The results indicate that most of the middle school students interviewed knew that matter was composed of atoms and molecules and some of them were able to use this knowledge to explain some processes such as phase transitions of water. In contrast, almost no elementary students knew that matter was composed of atoms and molecules. However, the middle school students were unable to consistently explain material properties or processes based on their knowledge of material composition. In contrast to elementary school students, who had scientifically inaccurate but relatively consistent (macrocontinuous or macroparticulate) knowledge frameworks, the middle school students could not be classified as having consistent knowledge frameworks because their ideas were very fragmented. The fragmentation of middle school students' ideas about matter probably reflects the difficulty of assimilating the microscopic level scientific knowledge acquired through formal instruction into students' initial macroscopic knowledge frameworks. © 2005 Wiley Periodicals, Inc. [source] Web portal design guidelines as identified by children through the processes of design and evaluationPROCEEDINGS OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE & TECHNOLOGY (ELECTRONIC), Issue 1 2006Andrew Large The Web is an important source of information for school projects, but young users do not always find it easy to locate relevant material. A critical factor in success is the portal through which they search or browse web content. Traditionally web portals have been designed by adults with young users in mind, but there is very little evidence that the latter make use of them. In this paper design guidelines are elaborated for such portals that are based upon focus group and operational evaluations by elementary school students of two prototype web portals designed by two intergenerational teams, each comprising elementary school students and adult designers. The evaluations offer strong support for involving children throughout the design process for portals that both in presentation and functionality reflect the cognitive and affective needs of young users rather than adults.
