The motor and gestural competition determines the position within the group. Some societies have highlighted the nature of the motor energetic male, while q in girls have highlighted the aesthetic and rhythmic own sex. Nowadays, although attitudes are changing, the results are slow and unspectacular. 6.3.3.La school, the media and the middle school material should not let the Ds motor q occurs spontaneously and randomly. The younger the child + + varied and diverse opportunities should receive. The mass media, especially TV, have great influence (vicarious learning) in the drive to the young. The facility to explore space and tb materials will influence the motor. The materials whose characteristics can change them, encourage children to perform> features not manipulative. Qa Kerkowitz She said the choice of materials must consider: _ = Materials with shape, but with ? sizes. Materials _ q children can manipulate and adapt to his motor and physical. _ Materials whose size is graduated and, pt, its complexity increases progresivax. The environment promotes physical and motor development, the process of socialization and manipulation.ITEM 7. ASSESSMENT INSTRUMENTS ENGINE DEVELOPMENT 1. Preliminary questions. 2. Instruments quinometrica evaluation. OBJECTIVES 1. Identify preliminary issues in the use of assessment instruments. 2. Analyze the properties (goals, age, etc.) of different assessment instruments. 3. Assessment tools in the driving Ds instruments have emerged to assess, analyze and study the motor status. Since 1930 numerous scales Ds mate engine: Gesell, Bayley, Shirley McCarthy or Denver Ds scale, or scale or Brunet-Lezin motometrica of Ozeretsky battery adapted by several authors to Europe, USA or Canada. 7.1. 7.1.1 Preliminary questions. Terminology-TEST: specifies a particular task performed by a subject explored q be a quality or aspect of psychomotor funcionam. -BATTERY: q T tests set the intention to assess and measure all aspects ? psychomotor. -SCALE: Test Suite shaped so as to provide a gradual difficulty to explore minuciosax Ds ? sectors. -REVIEW OR BALANCE: A set of tests or tests used to determine the Ds psychomotor reached by a subject.
