This evaluation focuses on the quality of content, the potential effectiveness as a Teaching-Learning tool, and the ease of use of the resource. This learning resource definitely presents valid concepts, model, and skills. The concept of graphing a linear function using the slope-intercept form, y=mx+b, is correctly used. The concepts of the slope (m) and the y-intecept (b) are correct, and the linear representation on the graph is also valid. The concept, model, and skill presented in this learning material is one of the most important ideas in the study of Algebra 1. To be successful in high school mathematics, students need to have an in-depth understanding of these concepts as well as mastery of the skills presented in this learning tool.
This material can be used in the "Practice" stage of the learning process. One of the learning objectives of this resource is to reinforce the understanding of the y-intercept when given the linear function in the form of y=mx+b and being able to graph it on a coordinate plane. Another goal is to reinforce the concept of slope, and how it can be used to assist in graphing a line. This should be targeted to students who are learning Algebra 1. It provides teachers with a different medium of presenting information and reinforcing concepts, and at the same time, provides students with a different way to practice and learn what has already been introduced to them prior to this learning activity. This software can easily be integrated in the Algebra 1 curriculum. It can be used at various occasions during the teaching and learning of linear functions. It is relatively a "basic" reinforcement resource and does not extend to other levels of understandings of linear functions. This resource, however, does have a link for students to review topics/concepts that involve graphing lines. Access to this information allows teachers to use this learning tool as a revision/warm-up activity of graphing lines using the y-intercepts and slopes during the study of other Algebra 1 concepts as well.
Overall, this resource is relatively easy to use. The general layout, buttons, and text are visually distinct and consistent. It is easy to follow along, and the directions are clear and concise. It also allows students to click on the "hint" button if they are unsure of how to proceed. The software provides immediate feedback and guides students who are having difficulty on how they should solve the problem. The concept of graphing, the coordinate plane, and the slope-intercept form is commonly used in the Algebra 1 course/curriculum, so students should be able to recognize them easily. The resource is also well laid out and sufficiently attractive.
