Origami and Spatial Thinking of College-Age Students

Issues in applied survey research, including minimizing respondent burden to encourage survey completion and the increasing administration of questionnaires over smartphones, have intensified efforts to create short measures. We conducted two studies to examine the psychometric properties of single-item measures of four close-relationship variables: satisfaction, love, conflict, and commitment. Study 1 was longitudinal, surveying an initial sample of 121 college-age dating couples at three monthly phases. Romantic partners completed single- and multi-item measures of the four constructs, along with other variables, to examine test-retest reliability and convergent (single-item measures with their corresponding multi-item scales), concurrent, and predictive validity. Our single-item measures of satisfaction, love, and commitment exhibited impressive psychometric qualities, but our single-item conflict measure performed somewhat less strongly. Study 2, a cross-sectional online survey (n = 280; mainly through Facebook), showed strong convergent validity of the single-item measures, including a .60 correlation between single- and multi-item conflict measures.

ABSTRACTThis document approach the research phase of the Master's degree in mathematics didactics at the Caldas University, called comparative study between universal learning design and conventional methods as a strategy for strengthening spatial thinking and geometric systems in the children of the first grade of the Institución Educación Nuestra Señora del Rosario in Manzanares, (Caldas). The objective of this preliminary analysis is to evaluate the effectiveness of learning through the DUA and compare it with the traditional method.RESUMENEste documento abordó la fase de indagación del trabajo de grado de la Maestría en didáctica de la matemática de la Universidad de Caldas, denominado estudio comparativo entre el diseño universal de aprendizaje y los métodos convencionales como estrategia para el fortalecimiento del pensamiento espacial y los sistemas geométricos en los niños del grado primero de la Institución educativa Nuestra Señora del Rosario del municipio de Manzanares, (Caldas). El objetivo de este análisis preliminar consistió en evaluar la eficacia del aprendizaje por medio del DUA y compararlo con el método tradicional.
