It is not possible to achieve the objectives and skills of a program in economics, at the secondary and undergraduate levels, without resorting to graphic illustrations. In this way, the use of educational software has been increasingly recognized as a useful tool to promote students’ motivation to deal with, and understand, new economic concepts. Current digital technology allows students to work with a large number and variety of graphics in an interactive way, complementing the theoretical results and the so often used paper and pencil calculations. The computer algebra system Mathematica is a very powerful software that allows the implementation of many interactive visual applications. Thanks to the symbolic and numerical capabilities of Mathematica, these applications allow the user to interact with the graphical and analytical information in real time. However, Mathematica is a commercially distributed application which makes it difficult for teachers and students to access. The main goal of this paper is to present a new dynamic and interactive tool, created with Mathematica and available in the Computable Document Format. This format allows anyone with a computer to use, at no cost, the PES(Linear)-Tool, even without an active Wolfram Mathematica license. The PES(Linear)-Tool can be used as an active learning tool to promote better student activity and engagement in the learning process, among students enrolled in socio-economic programs. This tool is very intuitive to use which makes it suitable for less experienced users.

The use of technological learning tools has been increasingly recognized as a useful tool to promote students’ motivation to deal with, and understand, mathematics concepts. Current digital technology allows students to work interactively with a large number and variety of graphics, complementing the theoretical results and often used paper and pencil calculations. The computer algebra system Mathematica is a very powerful software that allows the implementation of many interactive visual applications. The main goal of this work is to show how some new dynamic and interactive tools, created with Mathematica and available in the Computable Document Format (CDF), can be used as active learning tools to promote better student activity and engagement in the learning process. The CDF format allows anyone with a computer to use them, at no cost, even without an active Wolfram Mathematica license. Besides that, the presented tools are very intuitive to use which makes it suitable for less experienced users. Some tools applicable to several mathematics concepts taught in higher education will be presented. This kind of tools can be used either in a remote or classroom learning environment. The corresponding CDF files are made available as supplement of the online edition of this article.

AbstractA Logistic-Normal random variable (Y) is obtained from a Normal random variable (X) by the relation Y = (ex)/(1 + ex). In Monte-Carlo analysis of decision trees, Logistic-Normal random variates may be used to model the branching probabilities. In some cases, the probabilities to be modeled may not be independent, and a method for generating correlated Logistic-Normal random variates would be useful. A technique for generating correlated Normal random variates has been previously described. Using Taylor Series approximations and the algebraic definitions of variance and covariance, we describe methods for estimating the means, variances, and covariances of Normal random variates which, after translation using the above formula, will result in Logistic-Normal random variates having approximately the desired means, variances, and covariances. Multiple simulations of the method using the Mathematica computer algebra system show satisfactory agreement with the theoretical results.

This research is expected to provide an overview and information on the effectiveness of the ‘Quick on the Draw’ cooperative learning model implementation, so that it can be used as a reference material and develop it in a vocational high school study. This research is a classroom action research, aiming to improve the quality or solving problems occurring in a subject group that is researched and observed as a level of success or impact of his actions. The effectiveness of the model is assessed by student activity, student learning outcomes, and student response to the use of the model. The total score of the student activity observation is 87.5% (85% < RA ≤ 100%) in ‘very active’ category. The percentage of students that are collectively completed is 100%, which means that the criteria for the effectiveness of learning devices are met. The interval of the student responses received from the average from student response poll became the class response, where the response of this class is at the range of 3.2 (͞R ≥ 3), meaning the average of overall response is positive and meet the criteria of the learning device effectiveness. The use of this learning model is expected to address the problems often faced by both teachers and students.

The study aimed to identify the effect of problem-based learning on the achievement of first grade students in mathematics. The researcher followed the semi-empirical approach by examining the effect of the independent variable at its three levels (the "problem-based learning" method, the "problem-based learning with the use of learning software" method and the "usual" method); The sample of the study consisted of (69) students from the first grade in the second semester of the academic year 1431-1432. The sample students were divided into three groups: the first of which was an experiment that was taught in a "problem-based learning" "Problem-based learning with the use of educational software", and the third was an officer taught in the "usual" manner, and the number of members of each group (23) students. The researcher prepared the [teacher's guide (1), the student activity record (1) for the first experimental group, the teacher's guide 2, and the student activity record 2 for the second experimental group, according to the proposed teaching methods in the engineering, ). The study groups were subjected to a pre - and post - mental test to measure the levels of memory and comprehension. The test consisted of (30) questions. It was prepared, tuned, codified, verified, and fixed to measure the differences between the average scores of the students of the three groups. The researcher used the data analysis statistically (ANCOVA), Alpha Kronbach and T-Test to validate the hypotheses. The study found the following results: There is a statistically significant difference at the level of significance (aa) 0.05) among the average scores of the first experimental group students who studied "problem-based learning", which obtained an average of (18.83) and the scores of the control group students and obtained an average of (14.87) in mathematics achievement for the experimental group. There was a statistically significant difference at the level of significance (aa 0.05) between the average scores of the students of the second experimental group who studied the method of "problem-based learning with the use of educational software", which obtained an average of (23.21) and the grades of students of the control group in the achievement of mathematics I got an average (14.87), for the benefit of the experimental group. There was a statistically significant difference at the mean level (aa 0.05) between the average scores of the students of the first experimental group, which obtained an average of (18.83) and the scores of the students of the second experimental group, which obtained an average of (23.21) in mathematics achievement for the second experimental group. Based on the results, the study recommended a set of recommendations for the activation of problem-based learning. In addition to some important proposals ..

<p><em>The teacher's speech dominates in interactive activities with students in learning Arabic. To realize communicative and interactive learning, the teacher obeys the maxim of quantity proposed by Grice, which is to speak as briefly and clearly as possible so that the information conveyed can be understood easily. This article examines how to comply with Grice's maxim of quantity in the teacher's speech in Arabic class interaction. This research uses a qualitative case study approach in which data is collected through the documentation method and then analyzed using an interactive method. The results of this study are, the observance of the maxim of quantity in the teacher's speech is used in several categories; namely, 1) Requestives "begging", 2) Requestives "Praying"; 3) Requestives Ask; 4) Questions "ask"; 5) Questions "probing", and 6) Prohibitives "Prohibiting". Compliance with the maxim of quantity in Arabic classroom interactions between teachers and students positively impacts student activity and makes learning more conducive.</em></p><p><strong><em>Keywords: </em></strong><em>the maxim of quantity, Speech act, classroom interaction.</em></p>
