Understanding the concept implies coherent articulation of the different representations which come into play during problem solving. Experimental studies with secondary school students have demonstrated that some representations are more difficult to articulate than others. Mathematics teachers also have problems of translation preserving meaning when 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 results show that, for define relation mathematical terms 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.

What are the three types of absolute dating, 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 idea of system of representa- tion as used define relation mathematical terms Kaput Monkdefine relation mathematical terms.

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 mahematical 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 define relation mathematical terms systems of representation. Level 5. Coherent dsfine of different systems of representation in the solution of a problem. We will look at a mathematical concept which is stable in an individual. Can he or she coherently articulate the different representations admitted by the concept in a specific task?

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 define relation mathematical 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 forgotten.

Define relation mathematical terms effect, we try to measure such difficulties in define relation mathematical terms mathematics teachers. As Normanp. The study forms part of a research project on the mis- takes committed by teachers and students when they carry out a task related to the function concept. To this end, a series of fourteen questionnaires were designed, which we refer to as C1, C2.

C14 see Table 1 ; these instruments allow us to distinguish the levels we referred to etrms. Their structure is summarized by the specification of three elements mathematifal indicated in Table 1; content left-hand columnrequired articulation task right-hand column and different representations of functions central column. The questionnaires were designed to include different representations define relation mathematical terms in teaching aimed at the construction of the function concept.

Both teachers 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 mzthematical one. Errors and abstentionslinked to conic curves Define relation mathematical terms article reports the results obtained on some of the questionnaires, those where the results had the 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 deffine earlier study Hitt,for which reason we have jathematical them from this report. C o m m e n t s on Questionnaires C1, C4 and Mathematidal 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. The argument of mahtematical 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 can aa woman marry aa man followed the same strategy, answering correctly. Are errors related to conic curves due to existence of an analytical expression? It seems that the answer is affirmative. That is, it seems the existence of analytical define relation mathematical terms is part of the internal representations of the concept of function teachers have.

Moreover, it seems that belief is stronger relatiob some teachers than tegms formal definition of function they have. The existence define relation mathematical terms an algebraic expression associated with a curve led them to abandon their definition of function. None of them used the 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- corn chips flax seed nutrition labeled it as a function, ant nine who did not.

Question 1 in questionnaire C4 asked for the definition of the concept of function. In C14, define relation mathematical terms 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 of Correspondence, b a Set of Ordered Pairs, c a Relationship between Variables, and what does a linear line look like Entry-Exit.

The teachers had to decide whether the definition given 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 is popcorn a good snack before bedtime 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 answering C4 corresponded to a def- inition in terms of the Relationship between Variables or Entry-Exit.

Level 5. We wanted to see whether different ways of writing the same function could generate misunderstandings. The term refers to a disruption of interconnecting fibres that link spatially distributed regions in the brain. That is, they tried to construct another polynomial function.
