Between the years 2001 and 2005, a total of 72,895 female mosquitoes were trapped during their season of abundance, and analyzed. They were sorted into 4,723 pools belonging to 20 Culicidae species from the Anopheles, Aedes, Ochlerotatus, Culex, Culiseta, Coquillettidia, and Uranotaenia genera. The aim was to detect arboviral RNA directly from mosquito(More)
In this paper, we present a blended e-learning experience consisting of supplying an undergraduate student population (in addition to traditional on-site classes) with a learning tool called OOPS (Object Oriented Programming System) and a testing system called SIETTE. OOPS is a problem-solving environment in which students can resolve Object Oriented(More)
OBJECTIVE To evaluate the diagnostic concordance between static electronic images versus glass slides for breast fine needle aspiration (FNA) cytology. STUDY DESIGN Nine malignant and 12 benign breast FNA cases were imaged using the Roche Image Manager, at a resolution of 1,024 x 768 pixels. A cytotechnologist or pathology resident selected five to nine(More)
One of the most popular student modeling techniques currently available is Constraint Based Modeling (CBM), which is based on Ohlsson's theory of learning from performance errors. It focuses on the domain principles to correct faulty knowledge and assumes that a student will reach a correct solution without violating these fundamental domain concepts.(More)
This paper introduces a set of resources that provide web learning environments with student modeling services. SAMUEL is a user modeling server for registering, updating and maintaining student knowledge data from different sources that use their own ontologies. In order to make inferences about student knowledge, it becomes necessary to establish(More)
In this paper we present a framework for constructing problem solving environments for assessing procedural knowledge, i.e. the student’s ability to apply his/her knowledge in order to accomplish a task. Our proposal combines the most recent technologies for web-based development (e.g. service oriented architectures, JSF, JBoss rules, etc.) with a(More)
When a quantitative student model is constructed, one of the first tasks to perform is to identify the domain concepts assessed. In general, this task is easily done by the domain experts. In addition, the model may include some misconceptions which are also identified by these experts. Identifying these misconceptions is a difficult task, however, and one(More)
One of the most popular student modeling approaches is Constraint-Based Modeling (CBM). It is an efficient approach that can be easily applied inside an Intelligent Tutoring System (ITS). Even with these characteristics, building new ITSs requires carefully designing the domain model to be taught because different sources of errors could affect the(More)
