Simulations are dynamic resources that have been found useful for communicating abstract fundamental ideas such as stoichiometry and several other concepts. In this chapter the authors present their recent work on designing and implementing an interactive simulation called Combustion Lab based on reaction stoichiometry - a topic that has continually been a challenge for chemistry learners. Several researchers have reported persistent student misconceptions in stoichiometry. In order to address this challenge, a novel computer simulation was developed to assess student understandings of stoichiometry based on student problem solving performance, and also to promote student conceptual understanding. The Combustion lab was particularly focused on the stoichiometry of these reactions, problem solving, and the relevance of stoichiometry for its everyday applications. Results of this sequential exploratory study show that the simulation was effective in revealing student understanding and student treatment of stoichiometry problems based on analysis of various data collected.

Reputation is an important organization asset, particularly in the era of e-commerce. In an online consumer-to-consumer (C2C) auction market, a trader’s reputation sends an important signal to his/her trading partners in their decision-making on C2C transactions, due to the nature of the anonymous transaction process. While prior research has shown that reputation systems, such as eBay’s Feedback Forum, facilitated buyer-seller transactions, several fundamental issues with the transaction mechanism remained unclear. Based on the empirical reputation data directly collected from eBay.com, we find that the distribution of reputation scores can be approximated in a geometric function. We analyze the formation of the distribution with a stochastic process model. The computer simulation using the Monte Carlo approach further validates the findings of the empirical study.

Processing Information

Crisiscom is a computer simulation of national decision makers processing information during a crisis. The project has several purposes: 1. It is designed to increase our understanding of the process of deterrence by exploring how far the behavior of political decision makers in crisis can be explained by psychological mechanisms. This is done by comparing the output of the highly simplified computer model based on principles of individual psychology with records of actual political behavior. 2. It is designed to put together a good deal of what we know about the psychology of deterrence into a rigorous and formal system and thus to serve as an integrating device for that body of knowledge. 3. It is designed to be used in human games of the type represented by Bloomfield's DETEX games to provide inputs for teams that cannot be staffed with humans and to represent aspects of the environment that are not played out by the human players. 4. It is designed perhaps ultimately to provide a way of simulating a variety of possible crises. It will be some time before we have enough confidence in the model to use it in such a semi-predictive fashion, but that cannot be ruled out.

AbstractIn proficiency testing (PT), the peer-group mean is conventionally computed after twice removing values exceeding the mean±3 SD. However, this adjustment fails if there are many outliers. In this study an iterative method was evaluated as a more robust way to estimate the means. The methodology repeatedly removes a proportion of the population (usually those exceeding the mean±1.6 SD), assuming the presence of a Gaussian distribution in the central portion, and reinflates the SD to compensate for the trimming. A computer simulation revealed that the estimated mean of a known Gaussian distribution was less affected by a subpopulation that overlaps the main population than was the conventional method. When the overlapping portions were removed, the iterative method predicted the true mean correctly. The method was applied to external PT results for 44 analytes. Although most peer-group distributions were clearly non-Gaussian, the segment included by the predicted mean±1.6 SD was regarded as Gaussian in 85.9% by the new method and 73.4% by the conventional method. The proposed methodology appears to be an improved way of estimating peer-group means.

The present research aimed to understand the concerns of 20 Learning-Disabled adolescents in their academic and Non-academic areas. This was an exploratory study using interview method, that probed expression of the challenges they face in their school. The sample was selected in a child guidance clinic in Delhi. They were led by directional open-ended questions, leading them to talk about their concerns in academic and non-academic areas. Findings indicated their feelings of dejection and demotivation, inappropriate manner of teaching, choice of subjects, judgements based on marks and feeling unheard. They were restricted for games, library, zero-periods, third language and activity periods and were taught by special educators instead of subject specialised teachers. This added to conflicts, maladjustment, inappropriate labelling, loss of peer group and a feeling of inadequacy. They added that reduced and simplified content, compromised expectations, simpler subjects offered by the boards have made the academic journey easier, but it has also kept their potentials from full bloom.

scholarly journals Who’s “mixing” the languages? Statistical-sociolinguistic analyses of differently developed bilingual practice of Albanian-speaking school pupils in German-speaking Switzerland

AbstractThe extent to which the many Albanian-speaking children and adolescents in Switzerland apply a bilingual mode differs considerably. As part of a larger project, a quantitative exploratory study seeks to understand whether the frequency of code-switching is determined by demographic, individual, and peer-group-related factors. The fact that no striking relationships between these factors can be observed will be discussed with a view to the specificity of Albanian migration. Furthermore, these results raise questions with regard to the determinants of bilingual practice and the characteristics of “prototypical code-switch-speakers.”
