The purpose of the present study was to investigate the predictive influences of epistemological beliefs, achievement motivation, learning approaches on sixth grade students&rsquo / achievement in classification concepts. The study was carried out in the fall 2006-2007 semester. One thousand forty one 6th grade students from twenty five randomly selected elementary schools in &Ccedil / ankaya district of Ankara participated in this study. In this study Turkish version of the Learning Approach Questionnaire, Epistemological Beliefs Questionnaire, Achievement Motivation Questionnaire and Classification Concept Test were used as measuring instruments to collect relevant data. Multiple Regression Correlation Analyses was computed in order to find out the contribution of students&rsquo / learning approaches, epistemological beliefs and achievement motivation to their achievement in classification concepts. The results revealed that these variables explaining 14% of the variation in students&rsquo / achievement in classification concepts. Stepwise multiple regression analyses was conducted in order to find out which variable best predicted students&rsquo / achievement in classification concepts. Students&rsquo / learning approaches were found to be the best predictor of achievement explaining 12% of the variance. The remaining 2% of variance was explained by epistemological beliefs of the students. Achievement motivation, however did not contribute to students&rsquo / achievement in classification concepts. Results also revealed significant positive correlations between students&rsquo / achievement in classification concepts, their learning goal orientations, epistemological beliefs and learning approaches. Students&rsquo / performance goal orientations, and self efficacy beliefs, however, were not found to be related to their achievement in classification concepts.

The purpose of this study is to examine the relationship between 6th grade students&rsquo / problem solving achievement scores after completing instruction on problem solving and their mathematics achievement mean scores related to Least Common Multiple (LCM), Greatest Common Factor (GCF), Sets and Whole Numbers topics obtained throughout the semester. In addition, the relationship between 6th grade students&rsquo / problem solving achievement scores after completing instruction on problem solving and their actual mathematics net scores obtained from Level Determination Exam (SBS) was investigated. In total, 170 sixth grade students from a private school in Istanbul participated in the study. The data were collected via three sources namely / Problem Solving Achievement Tests (PSATs), Mathematics Achievement Tests (MATs) and SBS exam. Quantitative methods were utilized to examine the research questions and a correlational design was used. The results of the statistical analysis showed that there was a significant positive correlation between students&rsquo / problem solving achievement scores after completing instruction on problem solving and their mathematics achievement mean scores obtained through out the semester related to LCM, GCF, Sets and Whole Numbers Topics. In addition, the findings of the analysis showed that there was a significant large positive correlation between the problem solving achievement scores after completing instruction on problem solving and students&rsquo / actual mathematics net scores obtained from SBS.

The main purpose of the study was to investigate the effect of origami-based instruction on fourth, fifth, and sixth grade students&rsquo / spatial ability in mathematics. More specifically, how origami-based instruction affected students&rsquo / spatial visualization and spatial orientation ability was examined. In addition, elementary students&rsquo / self-reported perceptions related to origami-based instruction was investigated. In other words, students&rsquo / attitude towards origami-based instruction, their views about the benefits of origami-based instruction and its connection to mathematics, and the difficulties that students encountered while making origami as well as by whom they overcame these difficulties were investigated. The data was collected from 38 fourth, fifth, and sixth grade students in a private school in Eryaman neighborhood in Ankara. The participants were given a Spatial Ability Test (SAT) as pretest and posttest in order to assess the effect of origami-based instruction on their spatial ability in terms of spatial visualization and spatial orientation. In addition, the participants were asked to write reflection papers related to origami-based instruction in order to examine their perceptions. The results indicated that there was a significant positive effect of origami-based instruction on elementary students&rsquo / both spatial visualization and spatial orientation ability. Moreover, the findings showed that students had positive attitude toward origami-based instruction where they wanted to continue origami-based instruction. Students also thought that origami-based instruction was beneficial for them especially in geometry topics in mathematics, and they have common views that origami-based instruction was directly related with mathematics. Furthermore, results revealed that students were generally encountered with folding and assembling difficulties, and they overcame these difficulties by themselves, by the help of the teacher, and by the help of their friends.

The use of mobile and social learning media for K-12 students continues to rapidly increase in both formal and informal learning environments. While many educational apps have been developed for adult visitors to museums and science and technology centres (STCs), very few programs exist that are specifically designed to meet the unique learning and interpretive needs of elementary students in these learning environments. This dissertation explores the inclusion and development of children’s ideas and digitally mediated interpretive activities for peers within the exhibits of the natural history gallery at the Royal British Columbia Museum (RBCM) in Victoria, British Columbia. In this triangulated case study, thirteen Grade 4 and 5 students, five museum interpreters, and six elementary teachers worked in teams to design educational apps for their peers using experimental software specifically designed for this project. Five design teams composed of 2-3 students, one teacher, and a museum educator designed a wide variety of science activities for the natural history gallery at the RBCM. The results of analytic triangulation indicate that mobile interpretive apps acted as imperfect but important educational mediating tools for the participants in this study. The analysis revealed that, despite initial preconceptions and frustrations students and educators had about mobile design and technologies, Grade 4 and 5 elementary students were capable and highly interested creating mobile science apps for the natural history galleries at RBCM. Students and educators designed content and activities that extended participant-based learning opportunities beyond the existing science programs and curriculum currently available at the RBCM. The dissertation concludes with an examination of how informal science institutions can move beyond educational interactivity to more participatory frameworks that include the ideas and voices of young people within mobile learning and educational app development at natural history museums and STCs in the future. / Graduate

The problem of this study was to determine the cognitive development sequence of music skills. This sequence was determined by finding the music skills level, the Piagetian developmental level, and the developmental art level for twelve students differing in reading ability and in the first through fourth grades.The students were individually tested, using Piaget's semi-clinical interview technique. The students were tested on seven Piagetian tasks, ten music tasks, and one art task. The validity was determined through the interview process. The examiner redirected questions until he was certain the subjects were responding from conviction. The reliability of the study was achieved through a test-retest procedure and impartial expert evaluation of the test sessions.

Introdução: A anemia ferropriva tem uma distribuição universal e atinge a população em geral acarretando conseqüências importantes para as condições de vida, em especial para grupos vulneráveis entre os quais estão os escolares. Objetivo: Identificar a ocorrência de anemia e seus fatores associados em alunos ingressantes no ensino fundamental de escolas públicas do município de São Bernardo do Campo. Metodologia: Este estudo utilizou dados secundários da pesquisa: "Contribuição para a promoção da saúde infantil em uma comunidade". A população foi constituída por uma amostra probabilística de 613 escolares com idades entre 5 e 9 anos. A caracterização demográfica e socioeconômica da população foi obtida por meio de um questionário estruturado. Para a avaliação do consumo alimentar foi utilizado um Questionário de Freqüência Alimentar (QFA). A estimativa da prevalência de anemia foi realizada pela dosagem de hemoglobina em sangue venoso. Foram considerados anêmicos os escolares com valores de hemoglobina abaixo de 11,5g/dL. Resultados: A prevalência média de anemia para o grupo estudado foi de 5,71% não havendo diferenças dessa deficiência entre meninos e meninas. A anemia mostrou-se associada à baixa escolaridade materna, situação de trabalho do chefe da família e ao maior número de irmãos, moradia com um único cômodo e ausência de água na residência. Os alimentos mais representativos como fonte de ferro foram: carnes, feijão e pão. Frutas e carnes, que auxiliam a absorção do mineral foram consumidas pela maioria dos escolares estudados. O Programa Nacional de Alimentação Escolar (PNAE), popularmente conhecido como "merenda escolar" mostrou-se representativo no fornecimento do mineral na alimentação dos escolares, e supre 50% do ferro total necessário. Conclusões: A alimentação referida no domicílio contém os itens de uma alimentação saudável. A alimentação fornecida às crianças pelo PNAE que anteriormente à fortificação das farinhas de trigo e milho não era representativa em ferro, atualmente supre 50% das recomendações diárias explicando a baixa prevalência de anemia encontrada. / The iron deficiency anemia has an universal distribution and it reaches some population groups with important consequences for their life conditions, specially for vulnerable groups as students ranged from 6 to 12 years. Objective: To identify the anemia occurrence and its factors associate in elementary beginner students of public schools in São Bernardo do Campo. Methods: This study had used some secondary data from: "Contribution to promote the children's health in a community". The population was constituted by a probabilistic sample of 613 students ranged from 5 to 9 years. The demographic, social and economic population shape had been known by a structure questionnaire. The Food Frequency Questionnaire (FFQ) was used to evaluate the food intake. The hemoglobin dosage in venous blood was used to estimate the anemia prevalence. The hemoglobin values under 11,5g/dL. Results: The anemia average prevalence for all groups that had been studied was 5,71%. There was no difference between the sexes. The anemia was associated with low school maternal knowledge, the family boss situation, and the biggest number of brothers and sisters, as well as a big association between the water supply and the kind of housing. The most representative food intakes as ferrous source were: meat, bean and bread. The auxiliaries to its absorptions were: fruits and meats. The school lunch had been showed a good representative as the mineral supplier for the students. It supplies 50% of the necessary and bio available ferrous. Conclusions: The food practical has been adequate. Previously the school lunch feeding wasn't representative in ferrous, but now, it supplies 50% of the recommendation, and it's the reason for the low prevalence of anemia that has been gotten in this study.

Ten experimental and 10 control subjects in elementary special education were exposed to a semester of contingency management procedures for up to 6 1/2 hours per day. The experimental group was taught by teachers who were exceptionally well trained and qualified behavior analysts, while the control group was instructed by teachers with varying degrees of expertise in behavioral techniques. Both groups were given the Bender Gestalt as a pretest and posttest to determine the effect of such treatment on the diagnostic indicators of "acting out" tendencies. Furthermore, the rate of actual "acting out" was measured for all subjects by counting the number of verbal corrections resulting in placement in time out and/ or warning of forthcoming time out during 20 class days of baseline and the last 20 days of treatment.

In order for America to retain its superior position in a global economy it is imperative that all students receive educational opportunities that will prepare them for the future. Currently, African-American economically disadvantaged students in the United States perform lower on standardized tests than their grade and age-level peers. Educators must find ways to improve the performance of students in this group in order to maximize future opportunities. Through a mixed-methodology approach, the current study finds three school factors that may positively impact the performance of African-American economically disadvantaged students: high expectations, student-teacher relationships and teacher effectiveness. Quantitative and qualitative analysis provides perspectives from principals primarily from a large urban school district on the impact of these factors on student performance.

How children perceive their physical ability is important in understanding their reported adequacy, preferences, and predilection of physical activity. This relationship is useful in identifying lifelong physical activity behaviors. Purpose: The relationship between perceived physical ability and classroom engagement was investigated in elementary school children. Methods: Students (n = 120) in grades K5 completed the Perceived Physical Ability Scale (PPAS) and the Children’s Self-Perceptions of Adequacy and Predilection for Physical Activity (CSAPPA). Results: A statistically strong significant positive correlation (r = .49, P < .01) was found between the PPAS and CSAPPA indicating that students with higher perceived physical ability also reported higher scores on the CSAPPA. The high CSAPPA scores are indicative of students having a higher likelihood of choosing physical activity over a non-active option. No significant differences were noted between males and females or across grade levels. Conclusions: Based on these results students who have a greater perception of their physical ability also report being more likely to select a physically active option when given the choice. The findings of this study are noteworthy as previous studies have shown that differences between male and female students may exist with similar measures. These results may be indicative of the environment that has been created at the study site. The study site promotes a culture centered on respect, care, and a growth mindset within its student body. Future research comparing student to teacher ratio, cohesive student groups, and school schedules should be conducted to compare students’ PPAS and CSAPPA results. Programs designed to enhance perceived physical ability and enjoyment of physical activity are needed to promote lifetime physical activity habits.
