Cutnell and Johnson has been the Number one text in the algebra-based physics market for over 20 years. Over 250,000 students have used the book as the equipment they need to build their problem-solving confidence, push their limits, and be successful. The tenth edition continues to offer material to help the development of conceptual understanding, and show the relevance of physics to readers lives and future careers. Helps the reader to first identify the physics concepts, then associate the appropriate mathematical equations, and finally to work out an algebraic solution

This open access report explores the nature and extent of students’ misconceptions and misunderstandings related to core concepts in physics and mathematics and physics across grades four, eight and 12. Twenty years of data from the IEA’s Trends in International Mathematics and Science Study (TIMSS) and TIMSS Advanced assessments are analyzed, specifically for five countries (Italy, Norway, Russian Federation, Slovenia, and the United States) who participated in all or almost all TIMSS and TIMSS Advanced assessments between 1995 and 2015. The report focuses on students’ understandings related to gravitational force in physics and linear equations in mathematics. It identifies some specific misconceptions, errors, and misunderstandings demonstrated by the TIMSS Advanced grade 12 students for these core concepts, and shows how these can be traced back to poor foundational development of these concepts in earlier grades. Patterns in misconceptions and misunderstandings are reported by grade, country, and gender. In addition, specific misconceptions and misunderstandings are tracked over time, using trend items administered in multiple assessment cycles. The study and associated methodology may enable education systems to help identify specific needs in the curriculum, improve inform instruction across grades and also raise possibilities for future TIMSS assessment design and reporting that may provide more diagnostic outcomes.

Individuals need the academic knowledge and skills that equip them to succeed in today's economy. Almost 90 percent of new jobs require more than a high school level of literacy and math skills. The knowledge content of work is increasing, education is the key to maintaining a competitive edge, and everyone in society benefits when student achievement in primary and secondary school increases. The Third International Math and Science Study (TIMSS) compared performance in mathematics and science by a half-million students worldwide at age ranges corresponding roughly to grades 4, 8, and 12, including 33,000 Americans. While U.S. students at the fourth-grade level were near the first in the world in science, and were above the international average in mathematics, by the eighth grade, U.S. performance had fallen to slightly above the international average in science and to below the international average in mathematics. The message of TIMSS is that the U.S. still has a long way to go to ensure that all children achieve at world-class levels.
