    Abstract:

    The power of feedback has been widely acclaimed in research on learning and motivation. However, in educational practice, feedback has typically been conceptualized as an outcome of learning efforts, and not enough attention has been given to its self-reflective role--as a beginning point in cyclical self-regulatory efforts to understand, motivate, and improve one's efforts to learn. This experimental study investigated the influence of various forms of feedback on college students' strategic efforts to learn to solve complex math problems. Participants were assigned randomly to one of five conditions: 1) control, 2) strategy instruction, 3) strategy instruction plus summative feedback, 4) strategy instruction, summative feedback, and formative feedback, and 5) strategy instruction, summative feedback, formative feedback, and adaptive feedback. Summative feedback indicated whether a solution was correct or incorrect, while formative feedback involved an indication of the sources of errors, and adaptive feedback referred to the student's application of feedback to correct errors plus the experimenter's indication of accuracy on adjustments made by the student. Students attempted to solve multiple examples of a novel mathematic task during an instruction phase, learning phase, and posttest phase. The results showed a positive linear trend between increasing levels of elaborative feedback students received and their performance accuracy. In addition, there was a positive linear trend for increased elaborative feedback and strategy adaptation after making errors. Thus, the optimal level of feedback during learning involved information about the source of errors accompanied by self-reflective practice in making strategic adaptations. Progressively elaborative feedback also had additive effects on the important self-reflection phase processes of self-evaluation and self-satisfaction. As hypothesized, self-efficacy predicted performance accuracy and strategy adaptation, as well as self-evaluation and self-satisfaction. Understanding about contexts that help students' to adaptively use feedback to self-regulate has significant implications for classroom assessment that directly fosters learning.

    Abstract:

    The study assessed mothers' knowledge and beliefs about child development and compared these results to their children's performance on a child outcome measure. It was conducted under the auspices of Save the Children, the non-profit agency. Data was gathered in both rural and urban areas of Tanzania, and included typically developing children, and children identified with developmental delays. The study also examined the relationship between the mothers' income and education levels and their knowledge and beliefs in respect to child development, the relationship between parenting style and self-efficacy beliefs, the development of the construct of self-efficacy in the Tanzanian context, and the effects of birth location and maternal age on child developmental outcome. Participants included 103 mothers and their children. Forty-nine resided in the urban location and 54 in the rural location. Parental knowledge and belief were assessed using the Health and Safety, Milestone and Parenting subscales from the Knowledge of Infant Development Inventory (MacPhee, 1981), the Maternal Self-Efficacy Scale (Teti & Gelfand, 1991), the Parenting Tasks Checklist (Sanders & Wooley, 2005), and the Parent Modernity Scale (Schaefer & Edgerton, 1985). Child developmental outcome was assessed using the Battelle Developmental Inventory Screening Test (Newborg, 2005). All measures were translated into Kiswahili and piloted on a small sample. Results indicated that a combined measure of parent beliefs was more reliable than results from the individual measures, however no relationship was found between scores on this combined measure and results on the child outcome measure. Significant differences were found in the scores of all the parent measures between mothers from urban versus rural areas of the country when controlling for other demographic variables. There was also a positive relationship between maternal education and scores on the combined belief measure. Item analyses on the measures highlighted parental beliefs about child-care and child development within the Tanzanian context. Findings from the study demonstrate the lack of intervention services for children with disabilities/developmental delays in rural areas of the country and highlighted the health and policy implications associated with this.

    Abstract:

    The objective of this study was to explore beginners' knowledge of short vowel letter-sounds and its relationship to children's word reading and spelling abilities. Twenty-four five and six-year-old children completed several tasks assessing knowledge of vowel letter-sound and sound-letter associations, word and pseudoword reading, and spelling. Performance on the vowel tasks was used to separate children into high and low vowel knowledge groups. All children learned to read two sets of simplified spelling words to criterion: one set with vowels, and the other set without. It was expected that children with high vowel knowledge would learn words containing vowels faster and with more ease than words without vowels, whereas children with less vowel knowledge would learn words without vowel letters with more ease. Findings suggested that order of acquisition of short vowels reflects not only teaching, but also the distinctiveness of articulatory features among the vowels. Children's mistakes in short vowel sound production showed usage of a letter name strategy. Short vowel knowledge was significantly correlated with reading and spelling performance. Children with high short vowel letter-sound knowledge learned significantly more words and in fewer trials than children possessing low short vowel letter-sound knowledge. Contrary to our expectations, however, vowel letters in the target words did not affect learning. Individual analysis of children's performance revealed that children who reached criterion in the learning task in fewer than ten trials had achieved mastery or near mastery to at least three vowel letter-sounds. Findings are discussed in terms of the role of automatization of letter-sound knowledge in word recognition theories, and the role of decoding in helping children acquire more vowel knowledge. Acquisition of the idea of a vowel system to represent letters and sounds may be particularly helpful in enhancing word learning and spelling.

    Abstract:

    This dissertation tested the varying branches of research that have explored the issue of automaticity and its relation to goals in sports. One view shows support for a process avoidance perspective on athletic skill development. Another contends that skill development is enhanced when deliberate attention is paid to the execution of a skill's sub-processes. A third social-cognitive view is represented in the current dissertation. This view is reflected in self-regulation theory and suggests that, while both views are valid, the learner must be capable of shifting adaptively from processes to outcomes following extended practice for optimal skill development to occur. Extended attention to processes and attributing errors to strategy are both proposed to represent expert self-regulatory practice methods. Forty novice participants were randomly assigned to one of four groups: a) Extended Process, b) Intermediate Process, c) Self-Shifting, or, d) Outcome Goal. Each group received identical demonstrations of a beginner forehand tennis stroke, followed by sixty attempts at the stroke. The Extended Process Group attended to process goals for forty of sixty attempts then shifted to outcome goals for the final twenty attempts. The Intermediate Process Group attended to processes for twenty attempts then shifted to outcome goals for the remaining forty attempts. The Outcome Goal Group attended to outcomes throughout the sixty attempts. A Self-Shifting Group determined for itself when to shift from processes to outcomes. Results generally supported hypotheses, with the Extended Process Group outperforming other groups on measures of forehand skill and accuracy, in particular following the final phase of practice.

  • REEXAMINING LINGUISTIC RELATIVITY: WHAT ADULT BILINGUALS CAN TEACH US ABOUT CULTURE, LANGUAGE, AND COGNITION

    Abstract:

    Extending Whorf's popular notion of linguistic relativity (LR) to bilingual contexts, one would argue that a speaker's first language (L1) influences her thinking and behavior under second language (L2) conditions. According to one interpretation of LR, inter-language relativity, L1 instills in its speakers habitual ways of thinking and thus influences their perception and categorization in L2 contexts. Under intra-speaker relativity, bilinguals follow either L1 or L2 patterns of performance, depending on L2 proficiency. Finally, according to usage-based accounts of language, there is no qualitative difference between mono- and bilingual speakers, and a bilingual's performance under L2 conditions is best viewed in terms of their ongoing engagement with L2. To investigate how much each interpretation contributes to our understanding of cognition, language, and culture, two studies were conducted with a sample of 45 adult Russian-English bilinguals. Each study was based on a popular research paradigm and tested all three interpretations of LR for their explanatory value. Study one utilized a one-word association task conducted in both languages, a common way to examine the conceptual organization of the bilingual lexicon. Study two utilized a different kind of association task to investigate influences of L1 (grammatical gender) under L2 conditions. In both studies, there was no evidence in support of either inter-language or intra-speaker relativity. There was evidence in support of usage-based accounts of language: bilinguals' use of informal English appeared to moderate their performance under L2 conditions.

    Abstract:

    Studies by Moats (1995), Mather, Bos, and Babur (2001), and McCutchen, et al (2002) have begun to identify the relationship between teachers' linguistic knowledge and what is known, scientifically, about how literacy is acquired by learners. Findings from these studies support the idea that linguistic knowledge--particularly knowledge of English phonology and orthography--is important for teachers of reading and can improve student outcomes in the early elementary grades. Moats (1995) and Mather et al (2001) found that teacher participants in their studies did not have the levels of linguistic knowledge that would enable expert teaching of reading. The present study takes the research on teachers' linguistic knowledge as its thematic source and examines how linguistic knowledge enhances teachers' thinking about early literacy. Three groups of first-grade teachers participated in the present study. The first two groups were recruited from organizations that offer training in multisensory methods of teaching reading such as the Orton-Gillingham, Spalding, or Wilson methods. Multisensory (MS) methods of reading instruction involve teaching students to use more than one sense to internalize the relationships between phonemes and the letters that represent them in print. Training courses for teachers generally involve a thorough analysis of English orthography as well as practice and feedback in use of the teaching methods. This study compared three groups of teachers: teachers who had received recent multisensory training (n=8), teachers who had received multisensory training more than one year ago (n=8), and teachers who had not been trained in multisensory methods (n=8). Participants responded to surveys that measured their level of linguistic knowledge, familiarity with popular children's literature, and their theoretical orientation toward the teaching of reading. They also watched two segments of a video, each featuring a child reading aloud with a teacher. For each segment, teachers responded to six prompts that were designed to tap their on-task thinking about beginning reading acquisition and instruction. While the three groups of teachers in this study did not differ significantly in their measured levels of linguistic knowledge, they did differ in the ways in which they responded to the video and prompts. Multisensory trained teachers made more specific comments about the readers in the video and suggested more teaching strategies in their responses to the prompts. Multisensory trained teachers also showed higher levels of approval for basic skills practices, and used specific information about the readers in the video to formulate teaching strategies. Implications for future research on the teaching of reading are discussed.

    Abstract:

    Managed care rations health care to populations by using gate keeping methods to counterbalance cost. Subsequently, managed care dictates treatment decisions made by practitioners. Managed care has been implicated in damaging relationships within the clinical practice of psychology that unethical and fraudulent practitioner behaviors, and undesirable the client-practitioner relationships. The present study built on the design and results from the pilot study. It was an attempt to explore the relationship between managed care and psychologists' &rsquo: unethical behaviors, and understand the characteristics, specifically empathy and narcissism, of psychologists who behave unethically when assigning diagnosis required by managed care companies. Of particular interest to this research was an examination of individuals who report incongruous personal ethical personal standards and behaviors. The pilot study revealed a sample of the participants who reported that they acted ethically and abided by professional ethical standards all of the time. These same individuals also reported that they would incorrectly diagnose a client who did not meet diagnostic requirements to receive payment for services through managed care. Participants included 101 mental health practitioners. Data were collected with an online survey, that included measures of personal characteristics, professional ethics, empathy (Spreng et al., 2009), narcissism (Corry et al., 2008), motivated reasoning, and diagnostic decisions. Correlational analyses indicated that personal and professional characteristics are positively related to practitioners reporting that there are reasons to assign unmerited diagnoses to clients. Conjoint analysis, using logistic regression, indicated that practitioners who reported that there are reasons to assign unmerited diagnoses to clients and unwavering adherence to the APA ethics code most frequently assigned unmerited diagnoses to fictional clients. A sub-group of the participants from the current work again reported that they acted ethically and abided by professional ethical standards all of the time but demonstrated unethical behavior. This finding and practitioner individual differences related to diagnostic behavior are both topics for fruitful future research.

    Abstract:

    A meta-analysis was conducted to determine the effectiveness of interventions designed to help college students acquire self-regulated learning strategies. Fifty-five primary studies were included in the analysis, and ninety-three effect sizes were calculated and grouped into three outcome categories: academic achievement, strategy use, and self-efficacy. Total sample size consisted of 6, 669 students. The overall weighted effect size (Hedge's g) for all studies was 0.335 (95% CI = 0.240, 0.431), a significant small to medium effect. Interventions were coded based on their theoretical bases: metacognitive, social-cognitive, motivational, or an integration of these. Moderator analyses were conducted on several variables: content area, group work, type of assessment instrument, computer-mediated instruction, type of college/university, randomization of subjects, and intervention length. These analyses showed different effect sizes, although moderators accounted for little of the between-studies variation. Educational implications and recommendations for future research are proposed.
