This research is motivated by the low mathematical reasoning ability of students in Indonesia, especially class XI students of the high school. The low mathematical reasoning ability of students can be seen from the test results that the researcher gave to 29 students of the high school students of class XI which measured three indicators of mathematical reasoning ability, namely: 1) performing mathematical manipulations; 2) provide reasons or evidence against the correctness of the solution; and 3) draw conclusions from the statement. Based on the results of the student's mathematical reasoning ability test, it was found that the students' mathematical reasoning ability was still low. on the second and third indicators more students who cannot do it than students who can do it completely and correctly. The low ability of students' mathematical reasoning can be caused by the learning process obtained by these students so that to develop it can also be done through the learning process.
The current learning process carries the theory of constructivism where teachers are required to provide opportunities for students to acquire their own knowledge. Active learning requires the help of interesting teaching materials so that they can lead students to the learning information they want to learn, one of which is by using teaching materials in the form of e-modules that are presented on the website. By using such teaching materials, students who have difficulty understanding the material when it is only presented in text form can more easily understand because the material in the teaching materials is presented in the form of learning videos. One of the materials that are difficult for students to master is the limit of algebraic functions. Seeing these problems, the researchers conducted research that aimed to: produce products in the form of website-based teaching materials for the limit of algebraic functions to facilitate valid and practical mathematical reasoning abilities of the high school students of class XI.
The form of this research is development research using the Borg and Gall model. The steps that must be followed to produce a product include: research and information collecting, planning, development of website-based teaching materials, preliminary field testing, product revisions, main field testing, product revisions, and dissemination. The development phase of website-based teaching materials starts from the research and information collecting. This phase consists of analysis of teaching material needs, material analysis, and analysis of student characteristics. Based on these three analyses, the researcher chose to develop a website-based teaching material on the limit of algebraic functions that can facilitate the mathematical reasoning abilities of the high school students of class XI. The next phase is planning. At this stage, the researcher designed the material, designed the appearance of the website-based teaching materials, and prepared a validity assessment questionnaire and student response questionnaire. The results of the design of materials and teaching materials are developed into first products at the next phase, namely the develop preliminary form of product
iv
phase. At this phase, the product that has been successfully developed will be validated by media experts as well as material experts. The purpose of the validation is to test the feasibility of teaching materials in terms of content, presentation, and language, as well as the feasibility of the website in terms of graphics, and programs.
The validation results carried out by the researchers concluded that the average percentage of validation scores of the three validators was 94.21%. Based on the validation criteria, the average is "high value", so this online learning material on the limits of algebraic functions can be practically tested with revisions. One of the validators' recommendations is to add the mathematical reasoning ability to each sample and practice question, and to provide a rating slip. The researchers modified the learning materials on the site based on the reviewer's suggestions.
The next phase after develop preliminary form of product is preliminary field testing. Verified and revised web-based learning materials tested on six students from Class XII IPS 2 of MAN 1Pekanbaru, whio have studied about algebraic functions and have the heterogeneous potential. From the results of the analysis of the limited test questionnaires, the advantages of using web-based learning materials include easy access to study materials on the web, the ability to use them without support/ tutorials, the appearance of web-based learning materials. attractive, Video is unique because it uses unusual audio, email availability. The modules are fun to use and the information provided in the training materials on the website is complete and easy to read and understand. Besides the advantages of using web-based learning materials, one disadvantage is identified as the background sound of the video is too loud, making it difficult to hear the explanation in the video. Based on these observations, the researcher corrected the background sound level for each learning video.
The revised product from the preliminary field testing phase is evaluated for its level of practicality during the main field testing phase. The main field testing phase were conducted with the participation of all students in Class XI IPA IT of MAN 1 Pekanbaru. The results of the student response distribution survey on the practicality of web-based learning materials show that web-based learning materials have a good response, with an average percentage of 83.3% for material on the limits of algebra functions, and is at a practical level. Based on expert validation, preliminary field testing results, and results of student response surveys, it can be concluded that the website teaching materials for the limits of algebraic functions meet the requirements for validity and practicality.
