The Professor’s Puzzle is designed as a handbook for new and aspiring professors to help them transition from the independent research of their doctoral program to classroom teaching. Unfortunately, acquiring a Ph.D. often does not involve real preparation for teaching. One cannot assume that mastering content necessarily means one is qualified to teach it. Drawing from years of experience training young faculty members, professor Michael S. Lawson gathers together the best of educational research and practices, leavened with the yeast of Christian theology, so that readers are equipped to put the “teaching puzzle” together. Ideal for aspiring professors in Christian higher education, as well as all who enter the teaching profession, so they may learn artful teaching and careful administration. The following translations are available from the publisher: Chinese, German, French, Russian, and Spanish.

Puzzle fanatics will enjoy the many riddles, illusions, cryptograms and other mind-benders offered for analysis." --Psychology Today "... a bristlingly clear... always intriguing survey of the history and rationale of puzzles....

"Traditionally, scientists have emphasized what they call the first and second natures of personality--genes and culture, respectively. But today the field of personality science has moved well beyond the nature vs. nurture debate. In Who Are You, Really? Dr. Brian Little presents a distinctive view of how personality shapes our lives--and why this matters. Little makes the case for a third nature to the human condition--the pursuit of personal projects, idealistic dreams, and creative ventures that shape both people's lives and their personalities. Little uncovers what personality science has been discovering about the role of personal projects, revealing how this new concept can help people better understand themselves and shape their lives"--Provided by publisher.

Nancy and her friends must try to figure out why a girl is acting strangely after visiting a haunted house in this sixteenth book of the Nancy Drew Diaries, a fresh approach to the classic mystery series. Nancy’s classmate, Willa, needs her help. Willa is convinced something is terribly wrong with her friend Izzy, but everyone has dismissed Willa’s concerns, saying it’s just teen angst. But Willa thinks it’s more than that; she thinks Izzy is possessed. It all started when Willa and Izzy snuck into an abandoned house with some of their friends. After running around and exploring, Willa went in to the basement and found Izzy staring into space. Izzy was conscious, but she was acting weird—she wouldn’t speak and she didn’t seem to recognize Willa. And when Izzy finally woke up from her trance, she had no memory of the previous few hours. Since then, Izzy’s continued to act strangely. She’s usually funny and easygoing, but now she’s high strung and has intense fits. Once she even threatened to hurt Willa. Nancy is sure there’s a rational explanation for all of this and has a feeling she’ll find it at the “haunted” house. But what she finds has her questioning her resolve. Could Willa be right? Is Izzy possessed by the ghost of Heliotrope Lane?
