NorthStar, Fourth Edition, a five-level series, engages students through authentic and compelling content and empowers them to achieve their academic and personal goals. The approach to critical thinking in both the Reading/Writing and Listening/Speaking strands challenges students to move beyond basic comprehension to higher-level analysis. Conceptualized to promote critical thinking, NorthStar infuses analysis, synthesis, evaluation, and application throughout every lesson, not just in a critical thinking section like in other series. Components: Print or eText Student Book with MyEnglishLab -- Building on the success of previous editions, NorthStar continues to engage and motivate students through new and updated contemporary, authentic topics in a seamless integration of print and online content. eText with MyEnglishLab -- Offering maximum flexibility for different learning styles and needs, a digital version of the Student Book can be used on iPad and Android devices. MyEnglishLab: NorthStar -- Students use MyEnglishLab to access additional practice online, view videos, listen to audio selections, and receive instant feedback on their work. Teachers assign MyEnglishLab activities to reinforce the skills students learn in class and monitor progress through an online gradebook. Teacher Resource eText -- Each strand of NorthStar has an accompanying Teacher Resource eText with the following: digital Student Book, downloadable achievement tests, classroom audio, lesson planners, video activities, videoscripts, teacher's manuals, answer keys, and a downloadable placement test. Accessible through MyEnglishLab: NorthStar. Classroom Audio CD -- Listening and Speaking audio contains the recordings and activities as well as audio for the achievement tests.
