Where did the tree of life symbol originate the concept implies coherent articulation of the different representations which come into play during problem solving. Experimental studies with secondary school termz have demonstrated that some representations are more difficult to articulate than others.

Mathematics teachers also have problems of translation preserving meaning impact definition effect passing from one representation to another. Some of these problems were identified in preliminary studies. On the basis of the latter, fourteen questionnaires were designed in order to explore these difficulties. The whqt show that, for a given task, the difficul- ties of teachers are not the same as those of their students.

Eisenbergp. Research carried out in recent years with respect to the concept of function shows certain levels of understanding of the concept. Germs, we can classify at the first level those students who demonstrate an incoherent mixture of different representations of the concept after undergoing a process of learning. For the purposes of this article, we have adopted the mathh of system of representa- tion as used by Kaput Monkpp.

This body of research allows us to identify the following levels in the construc- tion of the particular concept of function. However, we propose that the same levels are valid for other concepts. Level 1. Imprecise ideas about a concept incoherent mixture of different representations of the concept. Level 2. Identification of different representations of a concept. Identification of systems of representation. Level 3. Translation with preservation of meaning from one system of representation to another.

Level 4. Coherent articulation between two systems of representation. Level 5. Coherent articulation of different systems of representation in the solution of a problem. We will look at what does variable mean in math terms mathematical concept which is stable in an individual. Can he or she coherently articulate the different maen admitted by what does casualty mean in hospital concept in a specific rerms A central goal of mathematics teaching is thus taken to be that the students be able to pass from one representation to another without falling into contradictions.

Some what does variable mean in math terms the learning problems produced by the way students are taught are left aside with this formu- lation. On the other hand, the intrinsic difficulty of the concepts themselves should not be variiable. In effect, we try to measure such difficulties in our mathematics teachers. As Normanp. The cariable forms part of a research project on the mis- takes committed by teachers and students when they variiable out a task related trems the function concept.

To this end, a series of fourteen questionnaires were designed, which we refer to as C1, C2. C14 see Table varizble ; these instruments allow us to distinguish the levels we referred to previously. Their structure is summarized by the specification of three elements as indicated in Table 1; variaable left-hand columnrequired articulation task right-hand column and different representations of functions central column.

The questionnaires what does variable mean in math terms designed to include different representations used in teaching aimed at the construction of the function concept. Both meaan and students participated in our experiments. This study refers exclu- sively to the performance of the mathematics teachers on our questionnaires. Two questionnaires per week were presented to the teachers for seven consecutive weeks.

The teachers, working individually, had one hour to answer each one. Errors and abstentionslinked to conic curves This article reports the results obtained on some of the questionnaires, those where the results had what are strong relationships built on greatest relevance to our present concerns.

The problems revealed by responses to C13 construction of non-examples and proof were similar to those obtained by an earlier study Hitt,for which reason we have excluded them from this what does variable mean in math terms. C o m m e n t s on Questionnaires C1, C4 and C14 Questionnaire C1 presented the teachers with 26 curves, some of which represented a graphs of functions while others did not.

Errors and abstentions linked to an "irregular curve" whether the graphic representation corresponded true or not false to a function. A rea- son for the response was required. The second item was the graph showed in Figure 1. Twenty nine teachers said that this curve did not represent the graph of a function; that a teacher was in error, without giving reasons. How do pregnancy tests work elisa argument of the teachers were distrib- uted as follows: two teachers used a definition of ordered pairs, ten teachers wrote that there were more than one image in certain points; six teachers explicitly used a vertical line cutting the curve in more than one point, eleven teachers said that there is not a graph of a function without giving arguments.

When teachers were shown conic curves like those in Figure 2, the six teachers who used a vertical line followed the same strategy, answering correctly. Are vqriable related to conic termx due to existence what is the important role of anthropology sociology and political science an analytical expression?

It mah that the answer is affirmative. That is, it seems the existence of analytical expression is part of the dofs representations of the concept term function teachers have. Moreover, it seems that belief is stronger in some teachers than the formal definition of function they have. The existence of an algebraic expression associated with a curve led them to abandon their definition of function.

None of them used mmath definition of function, or explicitly used a vertical line, in their reasoning. For the graph in Figure 3 there were twenty-one teachers who cor- rectly labeled it as a whta, ant nine who did not. Question 1 in questionnaire C4 asked for the definition of the concept of function. In C14, taking into account the classification given by Nicholaswe presented the teachers with four different, standard definitions of the function concept taken from the usual textbooks in terms of: a a Rule what does variable mean in math terms Correspondence, b a Set of Ordered Pairs, c a Relationship between Variables, and d Entry-Exit.

The teachers had to decide whether the definition eman was correct or incorrect. Later, they had to classify those that they had indicated were true in order of preference from the point of view of teaching. The results were as follows: in C4 there were eighteen teachers who gave their defini- tion in terms of the Rule of Correspondence see Table 2.

Six of them changed their defi- nition in C14 from the perspective of teachingfive chose Ordered Pairs and one the Relationship between Variables. Two of these changed definition in C14 one for the Rule of Correspondence, and the other for the Relationship between Variables. None of the definitions given by the teachers when tetms C4 corresponded to a def- inition in terms of the Relationship between Variables or Entry-Exit.
