Adaptive chemical behavior is essential for an organism's function and survival, and it is no surprise that biological systems are capable of responding both rapidly and selectively to chemical changes in the environment. To elucidate an organism's biochemistry, its chemical reactions need to be characterized in ways that reflect the normal…

A significant proportion of American high school students struggle with reading comprehension. Theoretical models of reading comprehension might help researchers understand these difficulties, because they can point to variables that make the largest contributions to comprehension. On the basis of an extensive review of the literature, we created…

The theory of conceptual change is criticized because it focuses only on supposed underlying logical structures and rational process processes, and lacks attention to affective aspects as well as motivational constructs in students' learning science. This is a vast underestimation of the complexity and diversity of one's change of conceptions. The…

A model of reading comprehension of geometric proofs (RCGP) has recently been proposed by the authors. This article further investigates students' development of such comprehension based on this model, looking at the relationship between students' reading comprehension and their prior knowledge and logical reasoning. The results show that (1)…

This paper reports on the use of a constructivist-based pedagogy to enhance understanding of some features of solution chemistry. Pre-service science teacher trainees' prior knowledge about the dissolution of salts and sugar in water were elicited by the use of a simple diagnostic tool. The test revealed widespread alternative conceptions. These…

The development of a conceptual model that provides a theoretical framework for understanding the conative factors of desire, resourcefulness, initiative, and persistence in autonomous learning considered the related variables of gender, education level, age, and marital status. The relevance of these demographic variables is based on prior…

Standards are the results of concerted efforts to improve the quality of education found in distance education. Legal and ethical standards are needed to ensure a positive educational environment. Participants from different cultural, physical, economical, and intellectual backgrounds should have equal access to all the positive aspects of…

Purpose: This paper sets out to examine whether the process of accrediting prior experiential learning (APEL) as used in UK universities is the most appropriate approach for providing academic recognition for work-based projects and learning. Design/methodology/approach: Work-based projects that had already been assessed in the context of a…

In this article, the author shares her experience in teaching sixth grade Spanish at Autrey Mill Middle School in Alpharetta, Georgia. Through the school's implementation of the middle school teaming concept, the author and her colleague on the sixth grade team have teamed up with other teachers in order to provide reading and writing…

Problem-based learning (PBL) is a student centered approach whereby students deal with ill-structured problems while working in small groups. In this study, a path model was utilized to model the relationships among reasoning ability, learning approach, prior knowledge, motivational variables, and achievement in genetics in PBL classes. 126 eighth…

For decades the National Science Foundation has been funding the development of instructional materials whose design is based upon the recommendations of educational research. These recommendations include the idea that learning be sequenced and organized using an experiential learning cycle or an instructional model such as the Biological Science…

Background: Optimum sequencing of skills so that learners can benefit from the transfer of previous learning is an important issue in teaching and learning of motor skills. There is a lack of empirical evidence on the specificity and transfer of learning and its application to teaching/coaching situations. Purpose: To investigate the concepts of…

To know the age effects in foreign language learning for children in China, we made both qualitative survey on the English teachers, the students and their parents by means of questionnaire; and quantitative survey on the students' scores from junior 1 to senior 2 (5 years) in the secondary school by analyses between those (over 30 students) who…

Accounting educators struggle with ways to incorporate the development of critical thinking and communication skills into the curriculum. Case analysis is one tool for developing these skills. We examine whether students' case analysis scores improve as a result of participation in peer grading and peer review. We find that students improve their…

The ability to apply existing knowledge in new situations and settings is clearly a vital skill that all students need to develop. Nowhere is this truer than in the rapidly developing world of Web-based learning, which is characterized by non-sequential courses and the absence of an effective cross-subject guidance system. As a result, questions…
