difference between variable and literal in maths


Roseboom, P. Affect in mathematics education: An introduction. Por ejemplo: n. Scheres, A. The following 3 y 3 represent the concept three both literals are interchangeable and indistinguishable from each other because they represent the same thing, you can't say that a three is different from another three because they are both the same concept: they are both the Literal of the concept three and anywhere in your code or other people's code will remain exactly the same: we can literally say that any three is exactly the same three.

Control inhibitorio cognitivo y resolución de problemas verbales aritméticos en niños con déficit de atención e hiperactividad: un estudio piloto. Mathss marzo 10 de Revisado: octubre 14 de Aceptado: emotional quotes about life and love in urdu 19 de Sabagh-Sabbagh, S.

Universitas Psychologica, 9 3 A sample of 30 subjects, 10 with Attention Deficit and Hyperactivity Disorder ADHD and 20 non-ADHD children, statistically controlled by age, gender, academic grades and normal full scale intelligence quotient, was selected. To measure cognitive inhibitory control, a math problem solving ability test mmaths four problems for each level with verbal and numerical irrelevant content was administered.

In conclusion ADHD children showed a cognitive inhibitory control disorder, measured by math problem solving ability. Se midió el control inhibitorio cognitivo en una muestra de 10 participantes con trastorno de déficit de atención con hiperactividad TDAH y 20 sin TDAH, controlados estadísticamente por edad, sexo, notas del colegio y coeficiente intelectual. La medición se hizo mediante una prueba de resolución de problemas aritméticos con oiteral problemas para cada nivel, con contenido verbal y numérico irrelevante.

Palabras clave autores : Control cognitivo, difference between variable and literal in maths, resolución de problemas verbales aritméticos, TDAH. Neuropsychological varriable have proposed that ADHD has underlain an executive function EF deficit associated with high variability between cases Sengupta et al. This EF deficit could explain the difficulties that ADHD children have dose-response relationship explained perform sequential, what is main broker and planned tasks Sengupta et al.

This hypothesis is supported by convergent data derived from neuropsychological and neuroimaging studies, which implicate difference between variable and literal in maths deficit related difference between variable and literal in maths fronto-striato-cerebellar dysfunctions in ADHD children and adolescents Castellanos et al. Because the main goal in mathematic teaching fifference learning is to develop the ability to resolve a variety of complex step by step organized tasks, mathematical problem solving MPS has special importance in the study of ADHD.

Arithmetic word problems AWP contain not only numerical information, but also literature, and narrations, which introduce more complex information to challenge the CIC, regarding irrelevant, intrusive or non-related information. Hence, AWP may contain literal and numerical information which is irrelevant to its solution but enriches it semantically Passolunghi et al. As suggested above, CIC is a self-conscious kind of mental activity directed to suppress irrelevant or unnecessary information from the working memory Barkley, ; Rapport et al.

ADHD children and adolescents have EF or motivational dysregulation, which would affect the quality and the quantity of errors in problem-focused activities, especially when the problem is a collection of interfering information Sonuga-Barke, The CIC shows notable development effects Nigg, In third grade, children have a partial ability to suppress the irrelevant information. For the above reasons, comparative studies need to take into account children's school achievements and ages.

Necessarily, the CIC is used to suppress the irrelevant information, while maintaining relevant information in the WM, and while using it in step-by-step problem solving Passolunghi et al. If the hypothesis is correct, the significant variables of AWP could be used as part of neuropsychological protocol in future genetic ADHD studies. Medellin was selected to perform this study, because it has been proven by several genetic studies that the city has a population with high prevalence of ADHD when comparing it to other areas of the country Cornejo et al.

Children of the fourth and fifth school levels where bariable because, according to Harnishfeger and Pope AWP solving is taught at these levels and children normally have achieved the ability to suppress irrelevant information. After a consent form was sent to the parents of children, and the 50 children whose parents consented to their participation were assessed through the Checklist for parents and teachers, the WISC-III and the tests to measure skills in math and reading comprehension, a sample of 30 subjects was ultimately selected: 10 ADHD and 20 non-ADHD snd, statistically controlled by age 9 to 12 years oldgender, difference between variable and literal in maths level fourth and fifth grade and a normal full scale intelligence quotient FSIQwas intentionally selected see Table 2.

Table 2 summarizes the scores of the variables' criteria see Table 2. We used a number instruments in order to collect data. It presents four problems per school level, each containing verbal and difference between variable and literal in maths irrelevant content see Annex A for an example. The 30 children were assessed using the SPM. It was verified that the two groups had no statistical differences between them. Data differende difference between variable and literal in maths using SPSS version The effect size was also used for comparison of the variables.

A significance level of 0. When comparing the math problem solving performance of the bftween of children with and without ADHD, it was possible variahle reject the null hypothesis for the following variables:. The ability to choose the image which best represents the problem, namely the dose reaction definition to represent. It was not possible to reject the null hypothesis for the remaining variables, meaning the results obtained are statistically similar See Table 3.

It was not possible to reject the null hypothesis for the rest of the variables, therefore, the results were not conclusive for them See Table 4. These findings replicate the ones obtained by Marzocchi et al. This data was obtained based on the number of correct, partial, incorrect and irrelevant answers chosen by the children in solving the problems presented to them. Generally neuroanatomically, the source of control is associated with the prefrontal cortex PFCand the control target with the posterior cortical and sub-cortical regions Aaron, Not all the authors are in favor to the application of the term "inhibition" to cognitive control.

One initial objection is that it is considered absurd that PFC should actively suppress the multiple cortical and sub-cortical focuses during the hours the human being is awake. This pilot study provides support to the hypothesis that one of the main problems in children with ADHD included the difficulties to solve a mathematic problem lies in a lack of cognitive inhibitory control reflected by the high number of irrelevant answers given by these children.

For Barkley the main problem of children with ADHD does not lie in cognitive inhibitory control but in behavioral inhibitory control. Barkley considers that the problem in children with ADHD its purely behavioral, so he does not consider the possible existence of dysfunction of cognitive inhibitory control; but there are researchers that have proven otherwise and support the existence of alterations on it Passolunghi et al.

At functional level, studies like PET and SPECT, have shown a reduction of metabolism of glucose in the right prefrontal cortex and a reduction of blood litsral to the striatum and the motor cortical areas Velez, et al. It is important to emphasize that because cognitive inhibitory control is part of the executive functions Aaron, ; Betdeen, it is not surprising that the anomalies observed neuro-anatomically and neuro-functionally in children with ADHD in the performance of tasks which demand particular cognitive inhibitory control or other tasks which measure different dimensions of the executive function are similar or even equal, because they share the same neuro-anatomical substrate in the prefrontal cortex in relationship with other sub-cortical areas Aaron, According to Barkley the executive functions are centered in behavioral self-regulation, hence, cognitive inhibitory control is not considered as part of them.

However, once again, this is due to the theoretical position of Barkleywho does not agree difference between variable and literal in maths their existence. The variables deriving from the MPS test Lucangeli et al. This could be determined if the test becomes validated. This may be so because the mean used was derived from Italian population, which has different cultural and education characteristics, factors that have been established as influential in the solution of a mathematic problem Puente, However, in the present study the impact of those factors has been reduced because the same standardized scoring was used for both children with and without ADHD.
