Learning across boundaries:how parents and teachers are bridging children’s interests

When a young person discovers something that sparks an interest, opportunities to unlock even deeper levels of learning emerge as she becomes motivated to master her knowledge about a particular subject. This report presents findings from separate surveys of 1,550 U.S. parents and 600 pre-K–8 teachers on whether, to what extent, and how U.S. children ages 3–12 are linking their learning experiences across home, school, and community settings. The inquiry paid particular attention to the ways in which caregivers and teachers support and, in some cases, impede the development of young children’s interests and the learning associated with pursuing these interests. Focusing on differences across demographics, the developed environment, and socio-economic status while taking an equity perspective, findings highlight areas of weakness and strength in this ecosystem of connected learning, suggesting what we need to pay attention to if we are intent on facilitating seamless learning across boundaries.

How Much Knowledge Is Too Little? When a Lack of Knowledge Becomes a Barrier to Comprehension

Previous research has shown that students who lack sufficient reading skills, including decoding and vocabulary, fare poorly relative to their peers. However, this study suggests that a knowledge threshold may also be an essential component of reading comprehension. A sample of students took a background-knowledge test before working on a reading-comprehension test on the topic of ecology. Results revealed a knowledge threshold: Below the threshold, the relationship between comprehension and knowledge was weak, but above the threshold, a strong and positive relation emerged. Further analyses indicated that certain topically relevant words (e.g., ecosystem, habitat) were more important to know than others when predicting the threshold, and these keywords could be identified using natural-language-processing techniques. The findings underscore the importance of having reached a basic knowledge level to be able to read and comprehend texts across different subjects:

Knowledge and Practice: The Real Keys to Critical Thinking

Willingham, D. (May 2016). Knowledge and Practice: The Real Keys to Critical Thinking. Knowledge Matters, Issue Brief #1.

A strong body of evidence shows that analysis requires deep knowledge of the topic, and therefore critical thinking can’t be reduced to a set of skills and strategies. In short, to “think like a scientist,” a student must know the facts, concepts, and procedures that a scientist knows. Background knowledge is absolutely integral to effectively deploying important cognitive processes. What this means for teachers: (1) facts should be meaningful; (2) knowledge acquisition can be incidental; and (3) knowledge learning should start early.

 

Reading Comprehension Requires Knowledge — of Words and the World

E.D. Hirsch, Jr. Reading Comprehension Requires Knowledge — of Words and the World. American Educator (2013) 27, 10-29.

Research indicates that the chief cause of the achievement gap between socioeconomic groups is a language gap. Much work on the subject of language and vocabulary neglects a fundamental element of word acquisition that is so basic as to be almost invisible: The relationship between language and the world knowledge to which language refers is extremely strong — there is evidence that by teaching solid content in reading classes we increase students’ reading comprehension more effectively than by any other method. A good, effective language-arts program that is focused on general knowledge and makes effective use of school time will not only raise reading achievement for all students, it will also narrow the reading gap — and the achievement gap — between groups.
