Coverage of CS1 programming concepts in C++ and Java textbooks

Introductory programming: a systematic literature review

“…More formally, researchers have studied the concepts in introductory programming courses and the extent to which these concepts are covered. Most of these studies are fairly general, conducted either by surveys of academics [65,260,579] or by analysis of textbooks [68,434]. These are supplemented by the occasional paper surveying students to explore the difficulty of specific topics such as recursion and iteration [446].…”

Viral Diseases and the Neglected Commandment of Creation Care

“…16 The composition of the surface layers was forever altered: certain areas experienced greater erosion (when roots split rocks apart and acidification of ground water dissolved vulnerable rock layers), while other areas had less erosion and became bogs; vast regions became cooler because of the altered albedo. 17 Algae are now recognized to be accelerating the melting of glaciers by also decreasing the albedo of those ice masses. 18 These naturally caused geological changes are considered to be beautiful; but, to whatever extent similar changes can be attributed to humans, the latter are seen as detrimental and destructive.…”

“…Today, less than 2 percent does. 17 The "Manifesto" also notes that intensification of agriculture is good for the environment:…”

“…The outbreak was easily contained because there was no human transmission, but it highlights the dangers of introducing wild animals into our human environment. 17 An unmanaged and uncontrolled wild animal market is a melting pot of zoonotic viruses. Nipah virus represents another example of spillover due to human activities.…”

“…16 Computer programs often implement mathematics and algorithms to solve problems, and desirable characteristics include correctness, performance, and efficiency. 17 These contribute to the development and design of beautiful code.…”
