“…By contrast, the current experiments explicitly involved only processbased biology concepts. There is evidence that learners better remember sentences and/or paragraphs that describe cause-and-effect relationships (e.g., Beck, McKeown, Sinatra, & Loxterman, 1991;Fillenbaum, 1971), link beginning and end states in a coherent matter (e.g., McNamara, Kintsch, Songer, & Kintsch, 1996), and/or incorporate descriptions of events in chronological order (e.g., Blount & Johnson, 1973;Clark & Clark, 1968), relative to text materials that lack such information. These effects have been attributed to improved comprehension, memory organizational processes, and other mechanisms.…”
