This study used used co-occurrence network analysis to study the experience of college students when solving statistics or algebra problems. Students generated words to describe their perceptions of solving a standard deviation problem and a quadratic computation. Results indicated that the statistics problem was associated with words indicating "anxiety" and "confusion". Conversely, words, such as "relaxed and "familiar" were used to describe solving the quadratic computation. Additionally, rating scales measuring statistics anxiety, math anxiety, and math helplessness, showed that meth anxiety tended to predict statistics anxiety for all students, above and beyond math helplessness. <br>

Abstract.Mathematical knowledge is very important in the lives of people, therefore, it is necessary understand it and make good use of mathematics in everyday life. Therefore, the aim of this work is to identify whether there is a set of latent variables that allow explain the anxiety toward math on students at Instituto Tecnológico de Tuxtepec, Oaxaca. The study is quantitative; and the study sample was formed of 303 college students from several profiles of the social sciences and engineering areas. The instrument utilized, is the scale of Munoz and Mato (2007) and was applied face to face to sample of study, in order to get data that allow us measure mathematics anxiety. The results show that students consider about the exposed variables that, the most prominent variable is the anxiety toward mathematics when faced in real life situations. The results allow us to observe that the studied variables explained 81% of variance that explains the math anxiety; the remaining 19% is explained by other variables that have not been considered in this research. Hence, if the student increases their anxiety in one of those, for example toward compression of mathematical problems, other variables also increase as the results show that there is a direct relationship between them.Keywords: Anxiety, Mathematics, Attitude toward mathematics, mathematics evaluationResumen.Los conocimientos matemáticos son de suma importancia en la vida de las personas, por lo tanto en la actualidad es necesario entender y hacer buen uso de las matemáticas en la vida diaria. El objetivo de este trabajo es identificar si en los alumnos del Instituto Tecnológico de Tuxtepec, existe un conjunto de variables que pueden explicar la ansiedad frente a las matemáticas. El estudio es cuantitativo, la muestra de estudio se conformó de 303 estudiantes del nivel universitario del Instituto Tecnológico de Tuxtepec, Oaxaca, de varios perfiles de ciencias sociales e ingeniería. Se utilizó el cuestionario Muñoz y Mato-Vázquez (2007), para medir la ansiedad a las matemáticas. Los resultados muestran que los estudiantes consideran que de las variables expuestas, la más preponderante es la ansiedad que les causa las matemáticas cuando se encuentran en situaciones de la vida real. Los resultados dejan ver que las variables analizadas contribuyen con el 81% a determinar la ansiedad hacia las matemáticas, el 19% restante es explicado por otras variables que no han sido consideradas en esta investigación. De ahí que, si el estudiante incrementa su ansiedad en una de ellas por ejemplo hacia la compresión de los problemas matemáticos, las otras variables también se incrementan ya que los resultados muestran que hay una relación directa entre ellas.Palabras clave: Ansiedad, Matemáticas, Actitud hacia las matemáticas, Evaluación matemática.

In this brief report, we present MMPI-2 basic validity and clinical scale data of Latino-descent persons from Puerto Rico ( n = 290), Mexico ( n = 1,920), and the United States ( n = 28). All were administered one of three Spanish translations of the MMPI-2. A review of the mean scores of these respective groups indicates similarities across all scales. Differences among these three groups, with the exception of the Mf scale (which is keyed to sex), were well within the one standard deviation band. More importantly, these findings are promising given the fact that three different translations of the MMPI-2 were applied.

This study investigated the extent to which standardized reading performance, individual perceptions of reading and test taking skills, and test anxiety predict the amount of extended time needed to equalize test access for college students with disabilities. Thirty-seven college students with a specific learning disorder (LD) and/or an attention deficit hyperactivity disorder (ADHD) diagnosis who received university test accommodations were recruited to participate in this study, along with 37 controls. All participants individually completed standardized reading tests and rating scales, and a timed reading comprehension task in a group setting. Results indicated that participants receiving test accommodations utilized approximately 14% more time than control participants to complete the timed reading task. Regression analyses indicated that the differences in time required to complete the reading comprehension task were related to participants’ reading fluency and decoding, as well as perceptions of the strength of their reading and test taking skills.

Most construction managers use deterministic scheduling techniques to plan construction projects and estimate their duration. However, deterministic techniques are known to underestimate the project duration. Alternative methods, such as Stochastic Network Analysis, have rarely been adopted in practical contexts as they are commonly computer-intensive, require extensive historical information, have limited contextual/local validity and/or require skills most practitioners have not been trained for. In this paper, we propose some mathematical expressions to approximate the average and the standard deviation of a project duration from basic deterministic schedule information. The expressions’ performance is successfully tested in a 4100-network dataset with varied activity durations and activity durations variability. Calculations are quite straightforward and can be implemented manually. Furthermore, unlike the Project Evaluation and Review Technique (PERT), they allow drawing inferences about the probability of project duration in the presence of several critical and subcritical paths with minimal additional calculation.
