The book should not only be attractive and interesting, but also upto the mark with the age level of students, appropriateness of content, relevance, utility, etc. Every new book should be thoroughly evaluated before it is given a place in list of textbook or suggestive readings or after introducing in a course. An exercise for evaluating a textbook has been presented in the current book. For this purpose, a textbook for class IX Mathematics, introduced in schools, has been selected. The study goes through explaining various aspects of evaluating the book. It makes an effort to see the book through the lenses of teachers as well as students. The book looks forward to place teachers not just as mere followers of the book introduced, but as reflectors, too, upon various aspects of the book. http://www.merlot.org/merlot/viewMaterial.htm?id=732215 In this book, the entire study consisted of basically five phases. In the present investigation, the definition of standardization has been adopted as given by Roger T. Lennon i.e. here standardization means to determine validity, reliability and norms of the test. The definition is also mentioned in "Measurement in Physical Education" by Donald K. Mathews (1978) The five phases are as follows: Phase I: Planning and preparation of a test set of 50 questions from Trigonometry for class IX. Phase II: Percentage of agreeability or content-cum-face validity with the help of subject experts and field experts. Phase III: Group try out for Item analysis. Phase IV: The final try-out to obtain reliability Phase V: Developing norms for the test. The above design of the study is also supported by Lee J. Cronbach (1984). http://www.merlot.org/merlot/viewMaterial.htm?id=731857 'With MyScript© Calculator, perform mathematical operations naturally using your handwriting.Easy, simple and intuitive, just write the mathematical expression on the screen then let MyScript technology perform its magic converting symbols and numbers to digital text and delivering the result in real time.

Moving fractions to their correct place on the number line is the only way to return. By playing Motion Math, learners improve their ability to perceive and estimate fractions in multiple forms.Loved by children as young as 7 and as old at 17 (and adults too!), Motion Math gives learners a physical experience of the number line and an intuitive feeling for fractions. Fractions are a notoriously difficult area and if a learner never gains a gut sense for them, it can impede progress in more advanced forms of math. One reason fractions are tough is that they can be written in so many different ways! Motion Math helps learners perceive and estimate many representations -- numerator over denominator (1/2), percents (50%), decimals (.5), and even pie charts.Motion Math was inspired by embodied cognition, research suggesting that connecting one's body to abstract concepts can deepen understanding. By estimating each problem with its distance on the number line, learners can develop a fast, accurate perception of fractions.----------ENGAGING PLAYThe Motion Math game follows a star trying to return to its home in a far-away galaxy. Moving up through different levels motivates a player to keep playing and keep learning, while bonus levels practice an important variation on the number line theme - is one fraction more or less than another? Progress stars, sound and star effects, and exclamations (“Yes!” “Perfect!”) reward a player for solving problems.----------PROBLEM HINTSIf a player is having trouble, increasingly helpful hints (what educators call "scaffolding”) guide him or her to the correct place on the number line.- First, a directional arrow is shown.- Next, tick marks show the fraction’s denominator.- Third, similar fractions are shown for comparison.- Lastly, in early levels, a vertical arrow shows exactly where to go.----------ADDITIONAL FEATURES- Intro level shows player how to tilt to control the star.- Later levels practice improper fractions and negative decimals.- Beginner, medium, and expert modes for different learners.'This app costs $1.99 http://www.merlot.org/merlot/viewMaterial.htm?id=713368 'Taking discrete mathematics?
