Pulling the other one: 1st- and 2nd-order visual information interact to determine perceived location.

Whitaker, David J., McGraw, Paul V., Keeble, David R.T., Skillen, Jennifer January 2004 (has links)
No / We demonstrate that the 1st- and 2nd-order characteristics of a visual stimulus can have a profound influence on each other in terms of perceived position. We use the parameter of spatial separation to selectively manipulate the effect of one characteristic upon the other. 1st-order features have their largest effect upon the perceived position of 2nd-order structure when separation is small, whilst the reciprocal effect is maximal at large separations. Implications for models of 1st- and 2nd-order interaction are discussed.

The 7th grade is considered to be at the center of the problem related to Mathematics learning at Basic School, as it is sustained by Scholar Efficiency Evaluation System of São Paulo State (SARESP) reports of 2005 and 2007. Besides, at this school level there is an expressive concentration of Algebra and its main content which is 1st order equation. For these reasons, our intention in this study is to identify and analyze those teachers concepts of 1st order equation, and investigate the relationships between these conceptions and teachers’ practices concerning 1st order equation.

Plodnost prvního pořadí a jedináčci v České republice / The fertility of first order and only children in Czech republic

Zikmundová, Iveta January 2015 (has links)
The aim of this thesis is an analysis of fertility of 1st order in the Czech Republic at period 1950 2014 including international comparision, an enumeration of cohort fertility and also analysis of structure and count of households according to number of childern. The thesis is divided into four parts for accomplishment of the aim. The first part focuses the theoretical interpretation and the analysis of fertility of order in the Czech Republic using indicators like number of live birth, total fertility rate, mean age of birth and portion of children born inside or outside of marriage. The second part compares level of fertility of 1st order in European countries according to NIDI 1999. The third part deals with cohort fertility which is ilustrated with complete cohort fertility rate and mean age at birth. The fourth part analyzes structure and count of complete and incomplete family households according to number of children. All parts are commented with context of progression of reproductive behaviour

Made available in DSpace on 2016-04-27T16:57:17Z (GMT). No. of bitstreams: 1 Juliano de Paula Mineli.pdf: 2480017 bytes, checksum: e6777d50d1d15cbae78249914a247c2f (MD5) Previous issue date: 2012-06-15 / This research aimed to study the formation of skills of elementary school students to solve problems, or more specifically, problems whose solutions can be expressed by 1st order equations. My teaching experience has made me raise a hypothesis that the difficulties that students encountered in the organization of the equation, related to the situations of Generalization of Patterns. From then define the objectives of this research is to: investigate problems related to skills training for the Generalization of Patterns and teaching situations to facilitate the training. For data collection, drafted a sequence containing three Curriculum Activities supported on the elements of Fractal Geometry, with a view to generalization of Standards and their implementation based on the Theory of Didactic Situations of Brousseau - theoretical framework used in this research.This sequence was applied in seven sessions to a class of 7th grade (6th grade) of a private Institution located in the city of Ribeirão Preto.This is a qualitative research study using a methodology supported by the Didactic Engineering. The observations and analyzes showed that: the characteristics of fractal figures provide pattern recognition, pattern recognition encourages students to make generalization, the use of geometric shapes provides better organization of data from a mathematical problem, which favors their resolution; generalization of a given situation helps the development of algebraic thinking as well as their attitudes and autonomy in order to observe, raising conjectures, draw conclusions and justify their answers / Esta pesquisa objetivou estudar formação de habilidades de estudantes do Ensino Fundamental para resolver problemas, ou mais especificamente problemas cujas soluções podem ser expressas por equações do 1º grau. Minha experiência docente me fez levantar uma hipótese de que as dificuldades que os estudantes encontravam, na organização da equação, relacionavam-se à situações de Generalização de Padrões. A partir daí definimos os objetivos desta pesquisa que são: investigar dificuldades relacionadas à formação de habilidades para a Generalização de Padrões e de situações de ensino facilitadoras para essa formação. Para a coleta de dados, elaborei uma Sequência Didática contendo três Atividades apoiadas nos elementos da Geometria Fractal, tendo em vista a Generalização de Padrões e sua aplicação baseada na Teoria das Situações Didáticas de Brousseau referenciais teóricos utilizados nesta pesquisa. Essa Sequência foi aplicada em sete sessões a uma turma do 7° ano (6ª série) de uma instituição privada situada na cidade de Ribeirão Preto. Trata-se de uma pesquisa de caráter qualitativo com metodologia apoiada na Engenharia Didática. Como conclusão podemos apontar que: as características das figuras fractais propiciam o reconhecimento de padrões; o reconhecimento de padrões favorece ao aluno realizar generalização; a utilização de figuras geométricas propicia melhor organização dos dados de um problema matemático, o que favorece sua resolução; a generalização de uma dada situação auxilia o desenvolvimento do pensamento algébrico, bem como suas atitudes e autonomia no sentido de observar, levantar conjecturas, tirar conclusões e justificar suas respostas

ŽELEZNÝ, Zdeněk January 2012 (has links)
This thesis deals with the solution of differential equations of the first degree. The work is intended to serve as a textbook (a collection of exercises) for students of teaching mathematics at lower secondary schools. Each chapter contains a summary of basic concepts, solved task models of the related topic, sorted by difficulty, and finally tasks assigned for independent practicing. This thesis aims to present basic knowledge about ways of solving differential equations of the first degree, including practical skills for their solution.
