Though guided-inquiry learning, discovery learning, student-centered learning, and problem-based learning are commonly believed to be recent new approaches to the teaching of chemistry, in fact, the concept dates back to the late 19th century. Here, we will show that it was the British chemist, Henry Armstrong, who pioneered this technique,…

Drawing primarily on interview data from a 5-year ethnography on the school experiences of Mexican immigrant children in a New Latino Diaspora community, we explore how their teachers understood and responded to increasing deportation-based immigration practices affecting children's lives. We illustrate how teachers fell along a continuum…

Numerous educational reforms have been initiated in Serbia since 2000. The aim of this study was to examine education policymaking in Serbia in order to provide policymakers and stakeholders with recommendations on how to minimize pitfalls and increase success of future educational endeavors. In the study, we utilized the education policy cycle…

The purpose of this narratological heuristic multiple case study is to describe the specific components that teachers need in both their knowledge and skills to meet the individual needs of their students in a blended learning classroom. The study was conducted in six schools--elementary, middle, and high schools--located in a suburban district.…

This paper reports an innovative approach to teaching problem solving in secondary school mathematics classrooms based on a specifically designed problem-solving module.This approach adopts the science practical paradigm and rides on the works of Polya and Schoenfeld in order to give greater emphasis to the problem solving processes. We report the…

Although the process of diagnosing invariably begins with a heuristic, we encourage our learners to support their diagnoses by analytical cognitive processes, such as Bayesian reasoning, in an attempt to mitigate the effects of heuristics on diagnosing. There are, however, limited data on the use ± impact of Bayesian reasoning on the accuracy of…

One of the challenges for undergraduate students is to comprehend abstract and theoretical concepts in communication classes. Given today's college students' expectations for in-class interaction (Rocca, 2010), it is important that instructors integrate hands-on activities in their lesson plans while teaching theoretical concepts.…

Our aim in this article is to elaborate the role of training in representational change theory (RCT), particularly in terms of Ohlsson's (2011) spread of activation explanation (named "redistribution theory"), and to develop novel training manipulations that effect the re-encoding mechanism proposed by RCT (Ohlsson, 1992). Two…

An inconsistent database is a database that violates one or more of its integrity constraints. In reality, violations of integrity constraints arise frequently under several different circumstances. Inconsistent databases have long posed the challenge to develop suitable tools for meaningful query answering. A principled approach for querying…

Generally, universities have complex and large websites, which include a collection of many sub-sites related to the different parts of universities (e.g. registration unit, faculties, departments). Managers of academic institutions and educational websites need to know types of usability problems that could be found on their websites. This would…

Previous studies suggest in line with dual process models that interoceptive skills affect controlled decisions via automatic or implicit processing. The "framing effect" is considered to capture implicit effects of task-irrelevant emotional stimuli on decision-making. We hypothesized that cardiac awareness, as a measure of interoceptive…

This dissertation investigates the temporal relation identification task. The goal is to construct consistent temporal relations between temporal entities (e.g., events and time expressions) in a narrative. Constructing consistent temporal relations is challenging due to the exponential increase in the number of candidates for temporal relations…

Problem solving task design is not only the design of a non-routine problem to be solves by the students. Our task design also requires a supporting document, the practical worksheet, which would act as a cognitive scaffold for the students in the initial stages of the problem solving process before they can internalize the metacognitive…

This study demonstrates the need for the integration of multiculturalism in the K-12 curriculum as well as provides a heuristic based on the work conducted by Sleeter and Grant (2009) to evaluate literature for level of multiculturalism. In the study, the researcher uses an evaluate heuristic to critically analyze and evaluation ten of the books…

In a cluster-randomized study, we investigate the impact of an argument-based approach to teaching science in elementary school on science learning and critical thinking skills. Forty-eight schools participated in the study, with data on 9,963 students across the 2 years of the intervention. Annual standardized tests assessing science content…
