This study focused on development of a portfolio evaluation tool to guide the assignment of valid and reliable scores. Tool development was facilitated by a literature review, guidance of a faculty committee, and validation by content experts. Testing involved a faculty team that evaluated 60 portfolios. Calculation of interrater reliability and a paired-samples t test were used to judge effect...

OBJECTIVE To adapt a pre-existing educational game, making it specific to the teaching of blood pressure auscultatory measurement, and to apply this game in a pilot study. METHOD The original game cards were altered by the authors and submitted to content validation by six experts in the field. After redesigns, the game was applied to 30 subjects, who answered a questionnaire (pre-test and po...

This paper presents a new approach to Automatic GUI Test Case Generation and Validation: a use case-guided technique to reduce the effort required in GUI modeling and test coverage analysis. The test case generation process is initially guided by use cases describing the GUI behavior, recorded as a series of interactions with the application widgets (e.g. widgets being clicked, data input, etc....

The validation of a test method is the process by which the relevance and reliability of the method are assessed for a particular purpose. It is an essential stage in the evolution of the method from its development to its acceptance and application for regulatory purposes. The principles according to which alternative tests should be validated have been agreed upon at an international level, a...

Cross-validation is an established technique for estimating the accuracy of a classifier and is normally performed either using a number of random test/train partitions of the data, or using kfold cross-validation. We present a technique for calculating the complete cross-validation for nearest-neighbor classifiers: i.e., averaging over all desired test/train partitions of data. This technique ...

veryfew attempts have been made in the past to develop instruments to measure pragmatic knowledge of second language (l2) learners. the absence of such instruments in the literature of english language teaching (elt) underscores the need for the researchers to develop new tests that are specifically designed to assess this crucial but less explored aspect of language learners’ (lls) knowledge. ...

Functional validation is one of the major bottlenecks in processor design: up to 70% of the design development time and resources are spent on functional verification. Simulation is the most widely used form of microprocessor validation. A major challenge in simulation-based validation is how to reduce the overall validation time and resources. Traditionally, billions of random tests are used d...
