The ability to solve mathematical problems related to purchasing and personal finance is important in promoting skill generalization and increasing independence for individuals with moderate intellectual disabilities (IDs). Using a multiple probe across participant design, this study investigated the effects of modified schema-based instruction (MSBI) on personal finance problem solving skills, purchasing an item on sale or leaving a tip, and using a calculator or iDevice (i.e., iPhone or iPad) for three middle school students diagnosed with a moderate ID. The results showed a functional relation between MSBI using a calculator on the participant’s ability to solve addition and subtraction personal finance word problems and generalize to iDevices. The findings of this study provide several implications for practice and offer suggestions for future research.

Problem solving is one of the basic abilities in mathematics learning. Problem solving skills can encourage students to think critically, creatively, and can develop other mathematical abilities. The research conducted aims to analyze students 'problem solving abilities in solving problems in mathematical problems and to determine students' self-efficacy towards mathematics. The approach used is a qualitative descriptive approach. The test given is a description problem and attitude scale to measure students' self-efficacy. Questions were tested on class VIII students in one of the junior high schools in the city of Bandung. The results of the study showed that as many as 1 student could not identify the adequacy of the data to solve the problem so that he got a score of 0, while 21 students were not precise in understanding the problem given, while 7 students could not complete the mathematical model and could not verify the correct solution, so it can be stated that the problem solving abilities of students in one of the junior high schools in Bandung are still low so that efforts need to be made to improve, but students have good self-efficacy in mathematics.

Problem solving is important for mathematical learning because it enables students to enhance high thinking skills and positive attitudes. This research aimed at describing and comparing the abilities of junior high school students in grade VIII from one of the regencies/cities in Central Kalimantan (Indonesia) in solving mathematical problems based on schools’ accreditations (A, B, C, and unaccredited), and schools’ status (public and private). The researcher gave three mathematical problems to the students from 20 samples of schools. The schools were randomly selected from the population consisting of 62 junior high schools. Each student’s solution was scored using a holistic rubric. The scores were summarized using some statistics represented in tables and graphics and were analyzed using a Kruskal-Wallis nonparametric test because the data were not normally distributed. The finding indicated that the average scores of the public and private schools’ students were 4.71 and 3.49 (scale 0-12), respectively. Based on the percentages, namely 1.91% and 39.66%, the students were classified as good and naive problem solvers, respectively. Further test revealed that the students from the A-accredited public schools significantly achieved the highest score for problem solving skills. Meanwhile, the students in the A-accredited and the unaccredited private schools did not show a significant difference in the skills. Similar result was also found in the public schools which were accredited B and C, and unaccredited.

El desarrollo de habilidades para resolver problemas ha de estar en el foco de especial atención por la importancia que reviste desde el punto de vista práctico. La resolución de problemas ha sido uno de los grandes pilares del aprendizaje de las matemáticas porque implica, entre otras cosas, saber integrar de manera coherente y con comprensión objetos, definiciones, representaciones matemáticas y saber usar esas configuraciones para encontrar respuestas correctas. Con ese objetivo, en esta investigación se ofrecen ejercicios que favorezcan la comprensión en la resolución de problemas matemáticos en los estudiantes de la Educación de Adultos. Estos se elaboraron en función de las principales causas de las insuficiencias identificadas en el contexto educativo tunero. Estos se enfocaron en reconocer otros modos o vías para resolver problemas, en la identificación de sub-metas, las posibilidades de los estudiantes para esbozar, graficar o modelar lo planteado y en plantear el problema con sus propias palabras. Además, es destacable la incidencia de la escala y el producto informático aportados para aplicarlos al desarrollo de investigaciones, en función de la recopilación y análisis de datos referidos a conjuntos lo más numerosos posible, donde destacan la variabilidad y la incertidumbre. La investigación fue realizada en la Educación de Jóvenes y Adultos de la provincia de Las Tunas, según un muestreo estratificado proporcional para un nivel de confianza del 93% y un máximo de error permitido del 9%. Esta se implementó en las 17 Facultades Obrera y Campesina distribuidas en cada uno de los municipios tuneros. PALABRAS CLAVE: Matemática; resolución de problemas; educación de adultos. EXERCISES TO PROMOTE UNDERSTANDING OF MATHEMATICAL PROBLEMS IN ADULT EDUCATION ABSTRACT The development of problem-solving skills must be in the focus of special attention because of its practical importance. Problem solving has been one of the great pillars of learning mathematics because it involves, among other things, knowing how to integrate objects, definitions, mathematical representations in a coherent and comprehensible way and knowing how to use those settings to find correct answers. With this objective, this research offers exercises that favor understanding in the resolution of mathematical problems in Adult Education students. These were developed according to the main causes of the shortcomings identified in the educational context of Las Tunas. They focused on recognizing other ways of solving problems, identifying sub goals, the possibilities for students to sketch, graph or model the problem, and posing the problem in their own words. In addition, the incidence of the scale and the computer product contributed to apply them to the development of research, based on the collection and analysis of data referring to as many sets as possible, where variability and uncertainty stand out. The research was carried out in the Youth and Adult Education of the province of Las Tunas, according to a stratified proportional sampling for a confidence level of 93% and a maximum allowed error of 9%.
