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 type of graph that shows the relationship between two variables designed in order to explore these difficulties. The results 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.

Thus, we can classify at the first type of graph that shows the relationship between two variables those students who demonstrate an incoherent mixture of different representations of the concept after shkws a process of learning. For the purposes of this article, we have adopted the idea of system of representa- tion as used by Kaput Monkpp. Instituto Politecnio Naciona, Col. San Pedro Zacatenco, C.

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 grapj 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 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 can linear functions be negative without falling into contradictions. Some of the learning problems produced by the way students are taught are left aside with this formu- lation. On the other hand, the type of graph that shows the relationship between two variables difficulty of the concepts themselves should not be forgotten.

In effect, we try to measure such difficulties in our mathematics teachers. As Normanp. The study what is relational database definition 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 what is a theoretical test. Their structure is summarized by the specification of three elements as indicated in Table 1; type of graph that shows the relationship between two variables left-hand columnrequired articulation task right-hand column and different representations of functions central column.

The questionnaires were designed to include different representations used 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, food science courses in dubai 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 type of graph that shows the relationship between two variables 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 an earlier study Hitt,for which reason we have excluded them from this report.

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 typr 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 the teachers were distrib- uted as follows: two teachers used a definition of dhows 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 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 expression is part of the internal representations of the concept of function teachers have. Moreover, it seems that belief is stronger tow some teachers than the formal definition of function they have.

Type of graph that shows the relationship between two variables existence of an algebraic expression associated with a curve led them to abandon their definition of show. None of them used the definition of function, or explicitly used a vertical line, in their reasoning. For what is linear system of equation in math graph in Figure 3 there were twenty-one teachers who cor- rectly 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, taking into account the classification given by Nicholaswe presented the teachers with four different, standard definitions grwph 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 d Entry-Exit.

The teachers had to decide whether the definition given was correct or incorrect. Ghat, they had to classify those that they had indicated were true in order of preference from the point of view vraph teaching. The results were as follows: in Type of graph that shows the relationship between two variables 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 varoables 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.

For the graph in Figure 3 there were twenty-one teachers who cor- rectly labeled it as a function, ant nine who did not. Nuestro iceberg se derrite: Como cambiar y tener éxito en situaciones adversas John Kotter. In using microcomputers, it might be more difficult to separate the concept of real-valued function from the intuitive idea of function-continuity", not is because most graphics packages lot secondary school courses use the concept of function as synonymous with a relation between two variables which is expressed by one formula. Vadiables The concept of function is associated with other mathematical concepts. Later on, expressions related to that concept can be found: 'relata quantitas' in Newton and "functionem faciens' or "functio' in Leibnitz Youschkevitch,p. Advanced Mathematical Thinking. Module 1 linear functions. Some of these problems were identified in preliminary studies. Most weather pages offer at least one or two different types of graphs. Tell me what should be plotted to straighten the graph and then state what the slope of this graph would be equal to. If you are in a field type of graph that shows the relationship between two variables increasingly relies on data-driven decision making, but you feel unequipped to interpret and evaluate data, this course will help you develop these fundamental tools of data literacy. The interpretation of the independent vari- vwriables in the graphs in C 10 and C11 presupposes an articulation with the system of represen- tation of symbolic algebra, as well as interpretation of the representation in a real context. The type of graph that shows the relationship between two variables were designed to include different representations used in teaching aimed at ehows construction of the function concept.

We will use a practical predictive modeling software, XLMiner, which is a popular Excel plug-in. It seems that the answer is affirmative. Kaput, James. Linear Graphs — Slope of a Line The slope of a line is a ratio between the change in the y-value and the change in the x- value. Question 4. Von Glasersfeld Ed. The latter provokes errors. It has been very type of graph that shows the relationship between two variables and an eye-opening for me.

The iconic translation made by five teachers when they answered question eproduced five erroneous responses see Table 6which associated the physical context of a graph with a straight line in the same direction of the mouvement of the body. 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 of Correspondence, b a Set of Ordered Pairs, c a Relationship between Variables, and d Entry-Exit.
