Discuss how robotics furthers engineering thinking and design among learners.
What will be an ideal response?
Answers will vary and include: Robotics has become part of an increasingly popular strategy for getting students interested in engineering principles and careers. Science-oriented curriculum, camps, and national competitions that focus on robotics have expanded their reach into all states. Creating and building robots requires engineering, including design thinking, problem solving, programming, and computational thinking. Students have expressed that they engage in collaborative work (Video Example 12.5) in the process of working with robots.

What will be an ideal response?
Which of the following statements is NOT a characteristic of frequency distributions?
a) They enable identification of clusters of scores. b) They identify isolated scores. c) They indicate the shape of a distribution. d) The scores are ranked according to their frequencies.
Planning and ________ are generally associated with prewriting
A) drafting B) organizing C) re-evaluating D) editing
A medical researcher was interested in examining what factors influenced patient’s scores in a fitness test. He ran a multiple linear regression, which included four predictors (‘hours spent taking part in physical activity per day’, ‘calories consumed per day’, ‘BMI’, and ‘hours spent sitting per day’). His model had a R2of .665, an adjustedR2of .661, an F-statistic of 112.56 (p 0.00). How would you interpret his findings?
A. It is not a significant model. B. It becomes difficult to assess the individual importance of predictors and it increases the standard errors of the b coefficients making them unreliable. C. It is a significant model where the four predictors account for 112% of the variance in the patient’s scores in the fitness test. D. It is an significant model where the four predictors account for 0.661 of the variance in the patient’s scores in the fitness test.
