The study analyzes students conceptions of the representational nature attributed to images in biology. The conceptions regarding the relationship between representation and referent can be categorized into realism and constructivism. 171 students aged 12, 14, and 16 participated in the study. Some had had specific instruction in biology and some had not. Several instruments, such as Likert scale questionnaires, and multiple choice and open-ended questions were used to measure the conceptions. Students show realistic conception about the nature of a cell microphotography. The primacy of perceptive aspects in visual representations may explain these results, the difficulties students have in learning them, and the need of their explicit instruction.

The conceptions regarding the relationship between representation and referent can be categorized into realism and constructivism. 171 students aged 12, 14, and 16 participated in the study.
Some had had specific instruction in biology and some had not.
Several instruments, such as Likert scale questionnaires, and multiple choice and open-ended questions were used to measure the conceptions.

The primacy of perceptive aspects in visual representations may explain these results, the difficulties students have in learning them, and the need of their explicit instruction. Este estudio tuvo como objetivo analizar las concepciones de los estudiantes sobre la naturaleza representacional de las imágenes en biología. Las concepciones sobre la relación entre la representación y el referente pueden categorizarse como realista o constructivista.
Para tal fin, 171 estudiantes de 12 a 16 años, con y sin instrucción específica en biología, respondieron cuestionarios de escala Likert, con preguntas abiertas y de opción múltiple.
