Plant nutrition from teachers thinking

In this work, it′s analyzed which contents related to plant nutrition are considered important by a group of secondary education teachers. Its objective is also to determine the existence of any correlations among teachers, depending on the selected and most valued contents in the evaluation activities and questions.The analysis of the obtained results has shown that the contents in which teachers are more focused are those describing the differences between autotrophic and heterotrophic nutrition, the photosynthesis process and the structures involved on it (plant and cellular organs). On the other hand, the less considered contents are related to the nutrition general concept, breathing concept and those associated to the ecological dimension of plant nutrition. The existence of certain trends among the teachers taking part in this study has been confirmed; a prevailing correlation has also been found. The majority trend is the physiogical.
