TL;DR: A geoboard has a board member with a plurality, advantageously four edges An array of holes which is preferably in the form of a matrix, is provided in the board member for receiving slidably mounted push-up pins Each pushup pin has upper and lower positions and the pins are arranged in the matrix for engagement by an elastic band to form shapes on the board members as discussed by the authors.
Abstract: A geoboard has a board member with a plurality, advantageously four edges An array of holes which is preferably in the form of a matrix, is provided in the board member for receiving slidably mounted push-up pins Each push-up pin has upper and lower positions and the pins are arranged in the matrix for engagement by an elastic band to form shapes on the board member Each of the edges includes spaced-apart notches for receiving fixed slider pins which extend in a row on a slider Each slider is slidably mounted along one of the edges for extending the matrix of push-up pins
TL;DR: The effect of using Geoboard in teaching Euclidean geometry in grade 11 mathematics learners is described in this article, where a qualitative research design was adopted in the study This design was preferred as it provides the conceptual understanding of the teaching methods of the teachers.
Abstract: The effect of using Geoboards in teaching Euclidean geometry in Grade 11 mathematics learners is described A qualitative research design was adopted in the study This design was preferred as it provides the conceptual understanding of the teaching methods of the teachers The participants were taught Euclidean Geometry with the use of Geoboard and an assessment was done and marks were recorded Thereafter, convenience sampling was used to select twenty (n = 20) participants from two secondary schools in the following order: eight (n = 8) of the top learners, four (n = 4) of the middle learners, and eight (n = 8) of the bottom learners were randomly selected from the Euclidean geometry test mark list to form four focus groups Only five (n = 5) participants were assigned to each group The study used the constructivism theory as the lens through which the data will be analyzed The data were collected by means of focus groups and analyzed using thematic analysis The findings of the study revealed that the Geoboard gives learners the freedom to learn on their own and in small groups while the teacher provides supervisory guideline using geometric theorem worksheets that support and guide learners It was also noted that a Geoboard allows learners to work collaboratively with their peers while promoting learner-centered learning
TL;DR: In this article, the Geoboard Triangles with One Interior Point (GTP) with one interior point are described. But they do not specify the interior point of the triangle.
