Pre-service teachers use e-learning technologies to enhance their learning

The purpose of this study was twofold. The primary purpose was to improve pre-service teacher education by using technology to help pre-service teachers bridge the gap between academic preparation and practice. The secondary, but still important, objective was to familiarize pre-service teachers in the use of technology to support their future pedagogical activities. Therefore, this research sought to develop a method for training undergraduate students in designing, implementing, and evaluating lesson plans to solidify the relationship between research, pedagogy, and teaching practice. Specifically, this study investigated the implementation of e-learning as a method of instruction to help pre-service teachers evaluate and improve upon the implementation of their lesson plans during their real world practicum experiences. The study was guided by the following research questions: 1) What successes, challenges, and benefits do university instructors and pre-service teachers experience in using and analyzing video in teacher education methods coursework? 2) In what ways did the use of e-learning help the pre-service teachers improve their teaching during the practicum experience? Results showed that participants reported improved lesson planning, improved lesson implementation, visual interpretations of best practices, modeling, and peer and university instructor feedback as successes of the e-learning project. Challenges included participants’ frustrations of being overworked and overwhelmed with the technical problems associated with e-learning. Overall participants judged the e-learning project as a very positive aspect of their teacher training

Negotiate or Litigate? Effects of WTO Judicial Delegation on U.S. Trade Politics

Goldstein and Steinberg argue that the World Trade Organization Appellate Body has been able to use its authority to engage in judicial lawmaking to reduce trade barriers in ways that would not otherwise have been possible through negotiation. This lawmaking authority was not the result of a purposeful delegation; rather, it was an unintended byproduct of the creation of an underspecified set of rules and procedures. There is nevertheless a high rate of compliance with Appellate Body decisions because decentralized enforcement can induce domestic importers to lobby for trade liberalization. In the US, this judicial lawmaking may also allow the President to achieve trade policies that are more liberal than those desired by Congress, if compliance can be achieved by a regulatory change or by sole Executive action

Special 301 : Its Requirements, Implementation, and Significance

This Article reviews the Special 301 provisions and their implementation to date. Special 301 is designed to use the credible threat of unilateral retaliation by the United States to persuade trading partners to reform currently deficient IP practices. The article praises the US\u27s use of Special 301 use thus far but warns against taking harsher action

Science education on the U.S./Mexico border: Field-based studies for future teachers in bilingual/binational schools

The University of Texas at El Paso’s field-based program of studies for future teachers provides opportunities for powerful learning through a dialectical union of reflection and action. Methods courses in academic disciplines are linked with seminars and coursework on community partnerships, dual language education and culturally responsive education. This article illustrates the processes of planning, implementation and evaluation of this approach, highlighting the impacts of forging connections among schools, communities and university personnel to improve education on the U.S./Mexico border and in communities with culturally/linguistically diverse student populations. Parents, students and future teachers interact in bilingual workshops that center on pupil achievement and conceptually correct science education. Preliminary outcomes indicate that two-way dual language (TWDL) bilingual programs (i.e., validating native language literacy along with English language acquisition) with a strong parental engagement component provide a strong framework for teaching/learning that can help improve educational outcomes for ELL/immigrant children and deepen future teachers’ skills and knowledge. Focusing on academic enrichment for all students, these field-based experiences enable future teachers to learn strategies that integrate students’ and families’ linguistic and cultural experiences as a resource for learning. The co-authors highlight qualitative data findings from the Science in Our Homes – Ciencia en Nuestras Casas field-based project in a multilingual, multicultural K-8 school on the U.S./Mexico border, providing insights for educators in diverse communities whose efforts focus on closing the achievement gap for English language learners and/or immigrant students

Psychological tools for knowledge acquisition

Knowledge acquisition is said to be the biggest bottleneck in the development of expert systems. The problem is getting the knowledge out of the expert's head and into a computer. In cognitive psychology, characterizing metal structures and why experts are good at what they do is an important research area. Is there some way that the tools that psychologists have developed to uncover mental structure can be used to benefit knowledge engineers? We think that the way to find out is to browse through the psychologist's toolbox to see what there is in it that might be of use to knowledge engineers. Expert system developers have relied on two standard methods for extracting knowledge from the expert: (1) the knowledge engineer engages in an intense bout of interviews with the expert or experts, or (2) the knowledge engineer becomes an expert himself, relying on introspection to uncover the basis of his own expertise. Unfortunately, these techniques have the difficulty that often the expert himself isn't consciously aware of the basis of his expertise. If the expert himself isn't conscious of how he solves problems, introspection is useless. Cognitive psychology has faced similar problems for many years and has developed exploratory methods that can be used to discover cognitive structure from simple data
