DIRECT AND INDIRECT EFFECTS OF PHONOLOGICAL ABILITY AND VOCABULARY KNOWLEDGE ON MATH PERFORMANCE IN ELEMENTARY SCHOOL
One merit of Trends in International Mathematics and Science Study (TIMSS) is that apart from a direct school students cognitive appraisal, it enables to collect information on teachers of these students, on their education, work experience and teaching practices. The first difference method was used to determine how teachers characteristics were associated with students achievements and to overcome restrictions of TIMSS correlation design. In addition, effects of teachers characteristics were evaluated by the conventional regressions method. The discovered associations differed across subject areas, and the first difference method results differed from the conventional correlation analysis results. For mathematics the first difference method revealed negative association of reproductive tasks and collaborative learning with achievements, and tasks aimed at comprehension and development of metasubject skills showed positive association. For natural science reproductive tasks showed, on the contrary, positive association, while tasks aimed at comprehension and development of metasubject skills either did not produce any effects, or they were negative. Also, for natural science, unlike mathematics, a teachers experience considerably influenced students achievements.
This article consider The project of the scientific and educational Center for integration of multimedia technologies in science, education and culture, as space-technological environment for the implementation of innovative scientific and educational projects of the 21st century, which should become the support for the master's programs, especially interdisciplinary; at the intersection of science, art and information technologies, and implementation of innovative scientific and commercial projects, which are to become a master's thesis.
The three already traditional volumes of the WDS Proceedings you are holding in the hands are composed of the contributions which have been presented during the 21st Annual Conference of Doctoral Students that was held in Prague, at Charles University, Faculty of Mathematics and Physics from May 29 to June 1, 2012. In this year, 100 student manuscripts were submitted to publishing and 88 were accepted after the review process.
Now we have the need for methodics of teaching the topic "parallel computing" in secondary school. The paper presents a three-year experience of the author in this field: a methodical approach, the selection of materials, the business games, experience of tasks on parallel computing at the contest "TRIZformashka", classes of tasks, examples of tasks, program executors, texts for propaedeutic textbook on informatics.
The present study tested the possibility of operationalizing levels of knowledge acquisition based on Vygotskyђs theory of cognitive growth. An assessment tool (SAMMath) was developed to capture a hypothesized hierarchical structure of mathematical knowledge consisting of procedural, conceptual, and functional levels. In Study 1, SAM-Math was administered to 4th-grade students (N = 2,216). The results of Rasch analysis indicated that the test provided an operational definition for the construct of mathematical competence that included the three levels of mastery corresponding to the theoretically based hierarchy of knowledge. In Study 2, SAM-Math was administered to students in 4th, 6th, 8th, and 10th grades (N = 396) to examine developmental changes in the levels of mathematics knowledge. The results showed that the mastery of mathematical concepts presented in elementary school continued to deepen beyond elementary school, as evidenced by a significant growth in conceptual and functional levels of knowledge. The findings are discussed in terms of their implications for psychological theory, test design, and educational practice.
This article presents the results of a pilot study assessing the level of formation of a stochastic competence among teachers of mathematics. Besides, the indicators that reflect the competence of formation of stochastic students are identified and ranked in order of importance. Different instruments (questionnaires, tests, assignments) have been used to solve the problem under study.
The authors estimate contribution of different factors in reading skills of 15?year-olds by using four models of multilevel regression analysis. It turned out that the most significant factor is family background — not only at the individual level, but at the school level as well (average school socio-economic status of schoolchildren families effects average reading skills). At the school level the aggregated family characteristics of students affect individual achievements, and this effect surpasses an effect of school resources and localization of schools — those school factors that show a significant contribution to achievement. Attitudes toward reading and learning are significant at the individual level, but at the school level children’s attitudes toward reading and school don’t make an independent contribution to the individual results.
In response to a growing demand for highly proficient speakers of foreign languages, both from private and government sectors, an added emphasis has been placed on developing communicative skills in the foreign language classroom. While time in a target language culture certainly plays a valuable and needed role, this research demonstrates that innovative curricular design and development in the university foreign language classroom can equal if not exceed uptake that occurs in extended immersion environments. A thorough description of the research design is provided, including the application of lexical items (connectors), listening, reading, written exercises, and videoconference debates involving students from National Research University Higher School of Economics in Moscow, Russia and Brigham Young University in Provo, Utah. Assessment instruments used to measure language uptake among students included pre- and post-written proficiency testing and oral proficiency interviews in one’s respective target language as administered by certified American Council on the Teaching of Foreign Languages (ACTFL) raters. In addition, students completed a background language questionnaire designed to elicit data relative to individual learner motivation.
The book is to be used as a supplement to an Upper Intermediate course in General English aiming to develop academic skills of reading and writing around the topics and vocabulary of 5 Units in the course book «Upstream Upper Intermediate» by Bob Obee –Virginia Evans (1, 2, 3, 6 and 9). Each section of the book includes instructions on developing basic reading and writing skills and several tasks to practise the skills.
Institutions affect investment decisions, including investments in human capital. Hence institutions are relevant for the allocation of talent. Good market-supporting institutions attract talent to productive value-creating activities, whereas poor ones raise the appeal of rent-seeking. We propose a theoretical model that predicts that more talented individuals are particularly sensitive in their career choices to the quality of institutions, and test these predictions on a sample of around 95 countries of the world. We find a strong positive association between the quality of institutions and graduation of college and university students in science, and an even stronger negative correlation with graduation in law. Our findings are robust to various specifications of empirical models, including smaller samples of former colonies and transition countries. The quality of human capital makes the distinction between educational choices under strong and weak institutions particularly sharp. We show that the allocation of talent is an important link between institutions and growth.
