The purpose of the study was to investigate the effects of inquiry-based computer simulation with heterogeneous-ability cooperative learning (HACL) and inquiry-based computer simulation with friendship cooperative learning (FCL) on (a) scientific reasoning (SR) and (b) conceptual understanding (CU) among Form Four students in Malaysian Smart Schools. The study further investigated the effects o...

Inspired by a quantum mechanical formalism to model concepts and their disjunctions and conjunctions, we put forward in this paper a specific hypothesis. Namely that within human thought two superposed layers can be distinguished: (i) a layer given form by an underlying classical deterministic process, incorporating essentially logical thought and its indeterministic version modeled by classica...

Many studies have reported that naming disorders may affect selectively certain semantic categories (animals vs. vegetables or artifacts, see Caramazza and Shelton, 1998, for a review) or syntactic categories (open vs. closed class items, Friederici and Schoenle, 1980, nouns vs. verbs, Baxter and Warrington, 1985; Caramazza and Hillis, 1991; Daniele et al., 1994; McCarthy and Warrington, 1985; ...

A concept to introduce external models in object oriented databases is presented, such that application programs do no longer interface directly the whole conceptual schema, but work against external schemas specii-cally designed for the applications requirements. There are virtually no restrictions for such applications, since the interaction with the database takes place via updateable views....

Since the early software models, abstraction and conceptual semantics have proven their importance in software engineering methodologies. For example, Object-Oriented conceptual modeling offers the power in describing and modeling real-world data semantics and their inter-relationships in a form that is precise and comprehensible to users. Conversely, XML is becoming the dominant standard for s...

To add time support to the relational model, both first normal form (INF) and non-INF approaches have been proposed. Each has associated dii]iculties. Remaining within INF when time support is added may introduce data redundancy. The non-lNF models may not be capable of directly using existing relational storage structures or query evaluation strategies. This paper describes a new, conceptual t...

Methods for Conceptual Clustering may be explicated in two lights. Conceptual Clustering methods may be viewed as extensions to techniques of numerical taxonomy, a collection of methods developed by social and natural scientists for creating classification schemes over object sets. Alternatively, conceptual clustering may be viewed as a form of learning by observation or concept formation, as o...

To add time support to the relational model, both rst normal form (1NF) and non-1NF approaches have been proposed. Each has associated diiculties. Remaining within 1NF when time support is added may introduce data redundancy. The non-1NF models may be incapable of directly using existing relational storage structures or query evaluation technologies. This paper describes a new, conceptual tempo...
