EMTEACHLINE MATH TEST AUTHORING SOFTWARE  TIMESAVING & COSTEFFECTIVE SOLUTION FOR MATH TEACHERS
Press release
ABSTRACT. EMTeachline Software has released a PCbased test authoring mathematics software package that offers a comprehensive set of test authoring tools for math teachers and a large repository of math problems in arithmetic, prealgebra, algebra, precalculus, trigonometry and hyperbolic trigonometry, with answers and solutions. Authoring options enable teachers to select math problems by topic, difficulty level and solution method, create printable math tests, quizzes, exams and homeworks of varied complexity and develop numerous similar variants around each constructed test. The software is suitable for elementary, middle and high school use.
1. MATH SOFTWARE OVERVIEW
Teaching problem solving skills in math requires a large amount of training in solving math problems. The EMTeachline Math Test Authoring Software EMTask helps math teachers in the organization of the teaching and learning process. Provide each student in your class with an individual practice test!
The software modules are organized by subject. Each module offers hundreds of math problem types, with dozens of similar problems within one type. Math problems of 11 levels of complexity are presented in a logical sequence from basic to advanced. All problems are solved in detail.
A comprehensive set of test authoring options makes preparation of math tests, quizzes, homeworks and exams an easy and creative work. With thousands of math problems at hands, teachers do not have to search for fresh examples. They can select math problems by complexity level, solution method and type of task; develop customizable math tests of varied complexity in a minute and generate up to 30 similar variants around each constructed test. All developed materials with or without the solutions can be printed out or stored in a file and reused. A set of variant tests is ready for students to review and reinforce their math skills.
2. MATH SKILLS COVERED
