Heavy content, high volume courses commonly create challenges for undergraduate students. Two such courses at our university are the introductory semesters of anatomy and physiology for first-year nursing students, taught by biology instructors. Despite the vast literature indicating the efficacy of using concept maps as a tool for learning, it is…

Teachers often encountered difficulties or even failure in conducting the classroom due to the students' inability to understand the learning materials. Most students find it's challenging to associate their existing knowledge with the new one because of the learning setting that they generally have. Teachers do not consider it important to set…

Young children's estimates of numerical magnitude increase approximately logarithmically with actual magnitude. The conventional interpretation of this finding is that children's estimates reflect an innate logarithmic encoding of number. A recent set of findings, however, suggests that logarithmic number-line estimates emerge via a dynamic…

This research applied the learning strategies to predict in an effect longitudinal growth of cognitive structure of students in biology. The aim of the research is to assess the effect of activating learning strategies on cognitive structures regarding biology. The research was conducted by using control group design. The sample of research was…

From the perspective of the Fuzzy Trace Theory, this study investigated the impacts of concept maps with two strategic orientations (comprehensive and thematic representations) on readers' performance of cognitive operations (such as perception, verbatim memory, gist reasoning and syntheses) while the readers were reading two history articles that…

When children learn to count and acquire a symbolic system for representing numbers, they map these symbols onto a preexisting system involving approximate nonsymbolic representations of quantity. Little is known about this mapping process, how it develops, and its role in the performance of formal mathematics. Using a novel task to assess…

Preschoolers made numerical comparisons between sets with varying degrees of shared surface similarity. When surface similarity was pitted against numerical equivalence (i.e., crossmapping), children made fewer number matches than when surface similarity was neutral (i.e, all sets contained the same objects). Only children who understood the…

This article describes a detailed analysis of knowledge building in a problem-based learning group. Knowledge building involves increasing the collective knowledge of a group through social discourse. For knowledge building to occur in the classroom, the teacher needs to create opportunities for constructive discourse in order to support student…

Twenty-three intermediate grade students (seven with learning difficulties) completed a concept mapping and vocabulary quiz, with instructions highlighting the value of learning goals or performance goals. Children with varying learning histories mediated in-school learning with qualitatively distinct epistemologies, and the "learning goals" task…

Differences in the status of ontological categories on the concept maps of secondary-, undergraduate- and graduate-level chemistry students were analyzed with the "Pathfinder" scaling algorithm and multidimensional scaling. Results indicate differences among groups in the structural significance of abstract process-related nodes and…

This study presents a quantitative method for scoring concept maps generated by students learning introductory college chemistry. Concept maps measure the amount of chemical information the student possesses, reasoning ability in chemistry, and specific misconceptions about introductory and physical chemistry concepts. They provide a visualization…

A control group of 40 eighth graders completed a unit on elements and compounds. An experimental group of 42 completed concept maps on the same topic. Results of a one-tailed T test demonstrated the usefulness of concept maps as advance organizers. (KR)

Discussed is the relationship of concept-mapping by students to the meaningful learning of genetics and ecological concepts. The implications of these results for teacher education in biology are addressed. (KR)

Reports on part of a larger study of how 11- and 12-year-old students construct knowledge of electricity and magnetism by drawing on aspects of their experiences during the course of a school visit to an interactive science museum and subsequent classroom activities linked to the science museum exhibits. (Contains 24 references.) (Author/YDS)

A longitudinal study of students' developing understanding of decimal notation has been conducted by testing over 3000 students in Grades 4 to 10 up to 7 times. A pencil-and-paper test based on a carefully designed set of decimal comparison items enabled students' responses to be classified into 11 codes and tracked over time. The paper reports on…
