How do learners make sense of what they are learning? In this article, I present a new framework of sense-making based on research investigating the benefits and boundaries of generative learning activities (GLAs). The generative sense-making framework distinguishes among three primary sense-making modes--explaining, visualizing, and…

We have developed a metabolic pathways visualization skill test (MPVST) to gain greater insight into our students' abilities to comprehend the visual information presented in metabolic pathways diagrams. The test is able to discriminate students' visualization ability with respect to six specific visualization skills that we identified as key to…

Biological systems and living processes involve a complex interplay of biochemicals and macromolecular structures that can be challenging for undergraduate students to comprehend and, thus, misconceptions abound. Protein synthesis, or translation, is an example of a biological process for which students often hold many misconceptions. This article…

Developing "Thinking and Understanding in Young Children" presents a comprehensive and accessible overview of contemporary theory and research about young children's developing thinking and understanding. Throughout this second edition, the ideas and theories presented are enlivened by transcripts of children's activities and conversations taken…

How can we teach science to English language learners (ELLs) when even our native English speakers have trouble reading the textbook? To help science teachers meet this challenge, this article presents six text-comprehension strategies used by English for Speakers of other Languages (ESOL) teachers: metalinguistic awareness development,…

According to the National Council of Teachers of Mathematics (NCTM) (1989, 2000), students at all levels should be exposed to geometry and measurement topics. Standards documents have identified the importance of primary school students selecting appropriate units for measurements in one- and two-dimensional space (NCTM 1989, 2000). This paper…

"Dimensional analysis" (or "factor-label") is the method most frequently used to teach reaction stoichiometry. However, because it is a strictly arithmetical approach, a pictorial framework that facilitates conceptualization of a reaction as a coherent process is advocated and described. (JN)

For English-language learners, comprehension can be hindered by a lack of understanding of homonyms, homophones, and homographs, but the right instructional strategies can alleviate this problem. Following a discussion of issues such as the importance of being aware of a student's literacy skills in his or her home language and the need to…

Describes a novel modeling and simulation package and assesses its impact on students' understanding of chemistry. Connected Chemistry was implemented inside the NetLogo modeling environment. Using Connected Chemistry, students employed problem -solving techniques characterized by stronger attempts at conceptual understanding and logical…
