Esta investigación tuvo como objetivo determinar la estrategia de aprendizaje predominante que se relaciona con el desarrollo de la autonomía de los estudiantes del VII ciclo de una institución educativa pública de Lima. Se desarrolló bajo el tipo sustantivo enmarcado y el enfoque cuantitativo. Su diseño fue no experimental y transversal correlacional. La población estuvo conformada por 171 estudiantes, a quienes se les aplicó dos cuestionarios. Los resultados demostraron que la estrategia de codificación de información ejerce mayor peso en el desarrollo de la autonomía de los estudiantes en cuestión. Así también, es una estrategia de riesgo que significa que un estudiante que no la maneje presentará siempre bajos niveles de aprendizaje autónomo.

Biomass (ф) production from Spirulina sp. batch cultures was optimized in laboratory scale photobioreactors (LPB) of 0.2 L, by the effect of X1: intensity of light emitting diodes (LEDs) and X2: photoperiod, between 1.25-41.7 klux and 12/12-24/0 hours of light/dark (L/D) respectively using a central composite rotational design (CCRD) and response surface methodology (RSM). The hydraulic characteristics and ф value from Spirulina batch cultures were also evaluated in a closed-loop channel photobioreactor open to the atmosphere (PB-CLOA) by the effect of the lighting LED of 8.3±1.9 klux and photoperiod of 12/12 and 24/0 h L/D. Two optimal zones of ф in LPB were identified, both with a 21.5 klux LED intensity and photoperiod relationship of 12/2 and 24/0 h L/D, with values of 1.65 and 1.62 ф respectively. The mathematical model which indicated the optimal zones was of 2nd order, which ...
