The purpose of this study was to determine the effects of a simulation with workedexamples on the creation of episodic memories and the troubleshooting ability of maintenance technician students. Previous research shows that domain knowledge, conceptual knowledge, strategic knowledge, and episodic memories are all required to successfully troubleshoot. While domain, conceptual, and strategic knowledge can all be taught using traditional instruction, episodic memories require students to experience the actual troubleshooting of a fault. Simulations and worked examples are two instructional methods that have proven effective at teaching troubleshooting. This research specifically examined how a simulation combined with worked examples would affect 1) immediate troubleshooting abilities, 2) the creation of episodic memories, and 3) delayed troubleshooting abilities. This study was conducted in two stages and administered via a learning management system due to COVID-19 restrictions. The first stage included a pre-test, a training session using the simulation with worked examples, and an immediate post-test for near and far transfer of troubleshooting abilities. The second stage occurred one week later and included the final posttest for near and far transfer of troubleshooting abilities and creation of episodic memories. Answers to four troubleshooting questions on each of the pre-test and immediate and delayed post-tests were collected to determine any differences in the immediate and retained troubleshooting abilities. Answers to the solution mapping questions were collected to determine the creation of episodic memories. A repeated measure analysis of variance was conducted in SPSS to analyze the results of the troubleshooting pre- and post-tests. A correlational coefficient was used to determine any interaction between episodic memories and delayed troubleshooting abilities. Previous experience levels and participants’ major of study were also examined to determine their effect on the results. The findings show the simulation with worked examples had a statistically significant effect on delayed troubleshooting abilities and the created episodic memories had a positive correlation with the delayed troubleshooting, both with a medium effect size. However, the simulation with worked examples had no statistically significant effect on immediate troubleshooting abilities. Levels of previous experience and participants’ major of study had little effect on the results.

Adversarial examples are among the most widespread attacks in adversarial machine learning. In this work, we define new targeted and non-targeted attacks that are computationally less expensive than standard adversarial attacks. Besides practical purposes in some scenarios, these attacks can improve our understanding of the robustness of machine learning models. Moreover, we introduce a new training scheme to improve the performance of pre-trained neural networks and defend against our attacks. We examine the differences between our method, standard training, and standard adversarial training on pre-trained models. We find that our method protects the networks better against our attacks. Furthermore, unlike usual adversarial training, which reduces standard accuracy when applied to previously trained networks, our method maintains and sometimes even improves standard accuracy.

When teaching discriminations, many researchers and practitioners recommend presenting multiple examples of both the correct and incorrect stimuli. To test this suggestion, we compared two procedures for presenting multiple examples. In one, multiple examples across trials (ME, Across), one correct (S+) and one incorrect (S-) stimulus were presented each trial; examples then changed across trials. In another procedure, multiple examples within trials (ME, Within), three stimuli (either 2 S+'s and 1 S-, or 1 S+ and 2 S-'s) were presented each trial; examples again changed across trials. Two experiments were conducted to test these procedures. The first procedure used a non-fading program to teach discrimination; the second used a fading procedure. In the first experiment, we taught 10 persons to identify words under these two procedures. The former procedure was superior in acquisition; the latter procedure, however, was better under generalization for most participants. In the second experiment, we presented the two procedures within a fading paradigm. The results replicated those in Experiment 1: ME, Across was better for acquisition, but ME, Within was better for generalization. Results were discussed and follow-up studies suggested.

Informed parent advocates are essential to planning the educational outcomes of their children with special needs in the K through 12 public school system. However, inappropriate instructional techniques used in advocacy training may reduce trainees' learning outcomes by adding complexity and increasing cognitive load. This study examined whether using worked examples to break down complex problems into component parts to build long term schema could lower cognitive load and thus improve learning outcomes for parent advocacy trainees. Based on cognitive load theory, this 2 x 3 factorial design study examined the efficacy of noninteractive video lessons for parent trainees using worked examples to reduce extraneous cognitive load. Research questions explored the relationships between the independent variables of using worked examples and parents' perceived class relevance on the dependent variable, change in cognitive load of parent trainees, as well as the interaction between training type and perceived class relevance. Two groups of 65 adults in advocacy training (N = 130) participated in a video lesson in either the worked examples or nonworked examples format as part of their advocacy training. The NASA Task Load Index and the Perceived Class Relevance Survey instruments were used to measure cognitive load of trainees and perceptions of training relevance. Key findings included a significant main effect between the use of worked examples and change in cognitive load and significant interaction effects with the perception of class relevance. Training was developed for advocacy trainers in the use of worked examples for learners new to a domain. Implications for social change include improved learning outcomes for parents who must learn IEP terminology in beginning classes to effectively advocate for their children.

Bayesian statistical methods have long been computationally out of reach because the analysis often requires integration of high-dimensional functions. Recent advancements in computational tools to apply Markov Chain Monte Carlo (MCMC) methods are making Bayesian data analysis accessible for all statisticians. Two such computer tools are Win-BUGS and SASR 9.2's PROC MCMC. Bayesian methodology will be introduced through discussion of fourteen statistical examples with code and computer output to demonstrate the power of these computational tools in a wide variety of settings.

This study was designed to compare the effects of the use of worked examples and self-explanation on motivation for male and female students. More specifically, the present study examines whether there are differences between males and females with regards to their achievement goals and if gender plays a role in how students respond to questions about their motivation in the presence of other male or female students. Comparisons of student responses on Achievement Goal Questionnaire-Revised (AGQ-R) and the Patterns of Adaptive Learning Scales (PALS) were also conducted. Participants were 147 seventh-, eighth- and ninth-grade non-honors Algebra I students (82 girls and 65 boys) from three schools and eight classrooms within the same school district on the east cost of the United States of America. Results replicated the finding that females have more mastery goals than males, however no gender differences were found for either performance. In addition, it appears that students respond differently to some questions about their motivation in the presence of other male or female students. Finally, the AGQ-R and the PALS appear to be consistent representations of students' achievement goals. / School Psychology

iii ABSTRACT The study focused on two competent, qualified, experienced secondary Mathematics teachers working in contrasting South African school contexts (fee-paying and no fee schools). The study investigated: on how teachers chose and used examples and how they explained their choices and usage; and what considerations were in play when these teachers chose and used examples. These teachers were purposely selected because we can learn more from their experiences as Mathematics teachers especially when they teach quadratic functions. Quadratic functions were used as unit of analysis to illuminate their choice and use of examples.

Esta dissertação tem por objetivo analisar a atividade docente de Ferdinand de Saussure (1857-1913) relativa à Linguística Geral, em 1907, quando o então experiente professor assumiu, pela primeira vez, o ensino da disciplina (Curso I). Nossos pressupostos teóricos provêm da Historiografia Linguística, tal como praticada por Auroux (1994), Koerner (1996) e Swiggers (2004). Nossa problemática parte do reconhecimento de que uma das maneiras de perpetuar a presença de Saussure no cânone dos estudos linguísticos consiste em repetir metáforas e exemplos a ele creditados, como a célebre metáfora do jogo de xadrez para ilustrar o conceito de língua. A partir de estudos historiográficos das funções semiótica e argumentativa de definições e de exemplos de língua (Rey, 1995; Quijada Van den Berghe e Swiggers, 2009; Chevillard et al., 2007), repartimos o material de análise (Saussure, 1996[1907]) em três porções, a que chamamos domínios (Caussat, 1978): Fonologia, Fonética e Analogia, temas do Curso I, para os quais estabelecemos três objetivos principais de pesquisa [1 a 3], e um objetivo secundário [4]: [1] levantar e caracterizar definições nos três domínios; [2] levantar e caracterizar os exemplos de língua nos três domínios; [3] correlacionar o uso de definições e de exemplos de língua nos três domínios; [4] correlacionar os dados apurados em [3] com com o contexto imediato de emergência do Curso I, ou seja, com o ensino da disciplina Linguística Geral na Faculté de Lettres et Sciences Sociales, em Genebra, em 1907 (Vincent, 2013). Nossas análises, que abarcaram 60 (sessenta) definições, apontam para a preferência de se construir uma definição pelo termo (definitio nominis), e não pela coisa (definitio rei), quando se trata de apresentar definições prioritárias ao assunto. Quanto aos exemplos, foram apuradas mais de 2000 (duas mil) ocorrências, com saliente revezamento entre francês e alemão nos três domínios, acompanhados por latim e grego, em uma representação das línguas-objeto feita principalmente por compreensão, ou seja, pelo uso generalizável dos exemplos de língua, que ilustram o conteúdo temático de maneira não-exaustiva. A unidade majoritária dos exemplos é a palavra, e sua disposição espacial preferencial são séries paralelas, ora em contraste simultâneo, ora em relação de sucessão temporal, com poucos paradigmas e declinações. As perguntas retóricas desempenham papel didático frequente e flexível, desde o teste de hipóteses até a apresentação de definições. Observamos, ainda, a ocorrência de definições que apresentam diretamente exemplos de língua, em uma relação bastante forte de interdependência. Reunimos, ainda, mecanismos de organização dos conteúdos temáticos (numerais, grafemas alfabéticos) e de esquematização (tabelas, símbolos e outras rupturas com a linearidade da exposição oral e da anotação escrita). Por fim, observamos estruturas de negação em todos os mecanismos investigados: definições que apresentam aquilo que não é antes daquilo que é, exemplos de língua que não ilustram determinado assunto, perguntas retóricas com respostas frequentemente negativas e oposições entre conceitos, de modo que as relações de oposição, algumas antinômicas, parecem caracterizar de maneira geral a didática de Saussure antes mesmo da formulação explícita do conceito de signo linguístico, que ocorreu, como sabemos, no curso de 1910-1911. / This paper aims to examine the teaching activity of Ferdinand de Saussure (1857- 1913) as to General Linguistics, in 1907, when the experient professor first started a course on the subject. Our work assumes that one way of perpetrating the canon consists of repeating some metaphors and examples accredited to him, as it goes to the famous saussurian chess game metaphor which illustrates the concept of langue. Our theoretical background lies on the Historiography of Linguistics, as professed by Auroux (1994), Koerner (1996) and Swiggers (2004), and the same applies for our methodological assumptions (Rey, 1995). Having established three separate domains within the first course (Saussure, 1996[1907]), Phonology, Phonetics and Analogy, we have then settled three main goals [1 to 3] and one secondary objective [4]: [1] to describe the definitions given in the three domains; [2] to describe and assess the language examples provided by the three domains; [3] relate the uses of definitions to those of language examples; [4] to relate [3] to the immediate context of emergence of the first course, the institutional background of General Linguistics at the Faculté de Lettres et Sciences Sociales, (Geneva, 1907). In order to accomplish the first step [1], we have adopted the classification of definitio rei, definitio nominis, as far as the definition incidence is concerned, and essencial, formal and functional definition, as to its content (Quijada Van den Berghe e Swiggers, 2009). The language examples [2] were analysed through their démarcation, the way they appear in the text; the way the languages being described are represented in the text, which can assume two forms: either par extension, when the totality of the cases are listed, either par compréhension, when the examples are models from which one can generate new instances (Chevillard et al., 2007). Our corpus comprises 60 (sixty) definitions and over two thousand examples. In general terms, the definitio nominis is enhanced when it comes to define priority terms, such as phonology. As to the examples, four languages appear intensely in the domains: french, german, greek and latin. These languages entertain a kind of representation mainly in comprehension.These instances occur as words, in horizontal and parallel series, scarcely in paradigms or declensions. There are definitions which exemplify overtly and directly, with no more material to accomplish a definition, which shows the strict interdependence of these constructions, together with a different mechanism, the rethorical questions. We have gathered, as well, organizing mechanisms (items, topics) and schematization procedures (tables, symboles and strategies that lessen the linearity of the text). Eventually, we have spotted the wide-spread use of negative strategies, such as defining something by what it is not, or excluding elements from a definition, as well as providing language examples which uncorrectly illustrate what is being said, in order to anticipate possible mistakes. Such procedures seem to be a hallmark on Saussures teaching.

As obras frequentemente consideradas como as mais relevantes para o estudo da filosofia kantiana são as três críticas que apresentam o rigor do pensamento filosófico e marcam uma mudança de perspectiva no pensamento moderno, apontando limites e novos horizontes para o conhecimento humano. Porém, concomitantemente ao desenvolvimento destas obras encontramos outras que também são importantes para a compreensão do projeto filosófico kantiano como um todo. Destaca-se no presente projeto de pesquisa a Antropologia de um ponto de vista pragmático e sua relevância para o estudo da formulação da noção moral a partir da observação das ações humanas e da possibilidade de identificação e formação do cidadão do mundo para Kant. / The works often regarded as the most relevant to the study of Kant\'s philosophy are the three critical presenting the rigor of philosophical thought and mark a change of perspective in modern thought, pointing limits and new horizons to human knowledge. However, concurrently with the development of these works find others that are also important for understanding the Kantian philosophical project as a whole. Stands out in this research project Anthropology from a pragmatic point of view and its relevance to the study of the formulation of the moral sense from the observation of human actions and the possibility of identifying and training the \"world citizen\" to Kant.
