Description
The purpose of this study was to investigate the impacts of visual cues and different types of self-explanation prompts on learning, cognitive load and intrinsic motivation, as well as the potential interaction between the two factors in a multimedia environment that was designed to deliver a computer-based lesson about the human cardiovascular system. A total of 126 college students were randomly assigned in equal numbers (N = 21) to one of the six experimental conditions in a 2 X 3 factorial design with visual cueing (visual cues vs. no cues) and type of self-explanation prompts (prediction prompts vs. reflection prompts vs. no prompts) as the between-subjects factors. They completed a pretest, subjective cognitive load questions, intrinsic motivation questions, and a posttest during the course of the experience. A subsample (49 out of 126) of the participants' eye movements were tracked by an eye tracker. The results revealed that (a) participants presented with visually cued animations had significantly higher learning outcome scores than their peers who viewed uncued animations; and (b) cognitive load and intrinsic motivation had different impacts on learning in multimedia due to the moderation effect of visual cueing. There were no other significant findings in terms of learning outcomes, cognitive load, intrinsic motivation, and eye movements. Limitations, implications and future directions are discussed within the framework of cognitive load theory, cognitive theory of multimedia learning and cognitive-affective theory of learning with media.

In times of fast paced technology, the ability to differentiate quality differences between a reproduction and an original work of art has new urgency. The use of digital reproductions in the classroom is a useful and convenient teaching tool, but can convey visual distortions specifically in regards to texture, size, and color. Art educators often struggle to achieve a balance between incorporating the use of digital technology and fostering an appreciation for experiences with original artworks. The purpose of this study was to examine the ways in which Dewey's theory of experiential learning explains how thoroughly high school students differentiate between a reproduction and original artwork. This study also explored the influences of painting style (realistic or semi-abstract) and sequence on a student's ability to identify the differences and select a preference between the reproduction and original artwork. To obtain insight into how a student is able to differentiate between a reproduction and an original artwork, this study engaged 27 high school student participants in viewing a digital reproduction and the respective original artwork of one realistic and one semi-abstract painting at the ASU Art Museum. Analysis of qualitative and quantitative data suggests that sequence influences a student's ability to differentiate between a reproduction and original artwork. Students who saw reproductions before viewing the originals, demonstrated a more comprehensive understanding of the differences between the two presentation formats. Implications of this study include the recommendation that art educators address definitional issues surrounding the terms original and reproduction in their teaching, and consider collaborative ways to prepare students for meaningful experiences with original artworks.

Description
Adolescents' clay sculpture has been researched significantly less than their drawings. I spent approximately six weeks in a ceramics class located at a high school in a suburb of Phoenix, Arizona in order to explore how gender affected subject matter preference in students' three dimensional clay sculpture. Gender studies on children's drawings reveal that males favor fantasy, violence, aggression, sports, and power, while females favor realism, domestic and social experience, physical appearance, care and concern, nature and animals. My three main research questions in this study were 1) How did gender affect subject matter in adolescents' three-dimensional clay sculpture? 2) What similarities or differences existed between females' and males' subject matter preference in sculpture and their subject matter preference in drawing? 3) Assuming that significant gender differences existed, how successful would the students be with a project that favored opposite gender themed subject matter? I found that although males and females had gender differences between subject matter in their clay sculptures, there were exceptions. In addition, the nature of clay affected this study in many ways. Teachers and students need to be well prepared for issues that arise during construction of clay sculptures so that students are able to use clay to fully express their ideas.

Description
This study examines the possibility of using social and historical contexts, image analysis, and personal themes to engage adolescent photography students in the craft of photography. This new curriculum was designed around large themes that correspond to the developmental stage of adolescence. Issues such as self-identity, teenage stereotypes, school, family, and community were explored through examining historical documents and photographs, comparing popular culture perspectives, and learning basic semiotics. The students then worked within these ideas by creating their own photographs and reflecting upon their art making choices. The new approach was implemented in an analog film class in which basic 35mm camera and film techniques are taught. It is argued that meaning making motivates the adolescent photographer rather than the achievement of strong technical skills. This qualitative study was conducted using an action research approach, in which the author was both the classroom teacher and the researcher. The study incorporates data collected from student-created photographs, student written responses, interviews of students, interviews of photography teachers, and the researcher's field notes. Major themes were discovered over time by applying a grounded theory approach to understanding the data. The curriculum brought a new level of student engagement, both in participation in the course and in the complexity of their image making. By incorporating the chosen topics, students' images were rich with personal meaning. Students retained concepts of historical and social uses for photography and demonstrated a base understanding of semiotic theory. Furthermore, the data points to a stronger sense of community and teacher-student relationships within the classroom. The researcher argues that this deeper rapport is due to the concentration on personal themes within the practice of photography. Setbacks within the study included censorship by the school of mature subjects, a limited amount of equipment, and a limited amount of time with the students. This study demonstrates the need for art curriculum to provide connections between visual art, interdisciplinary associations, students' level of development, and students' personal interests. The research provides a possible approach to redesigning curriculum for photography courses for the twenty-first century student.

Description
Lots of previous studies have analyzed human tutoring at great depths and have shown expert human tutors to produce effect sizes, which is twice of that produced by an intelligent tutoring system (ITS). However, there has been no consensus on which factor makes them so effective. It is important to know this, so that same phenomena can be replicated in an ITS in order to achieve the same level of proficiency as expert human tutors. Also, to the best of my knowledge no one has looked at student reactions when they are working with a computer based tutor. The answers to both these questions are needed in order to build a highly effective computer-based tutor. My research focuses on the second question. In the first phase of my thesis, I analyzed the behavior of students when they were working with a step-based tutor Andes, using verbal-protocol analysis. The accomplishment of doing this was that I got to know of some ways in which students use a step-based tutor which can pave way for the creation of more effective computer-based tutors. I found from the first phase of the research that students often keep trying to fix errors by guessing repeatedly instead of asking for help by clicking the hint button. This phenomenon is known as hint refusal. Surprisingly, a large portion of the student's foundering was due to hint refusal. The hypothesis tested in the second phase of the research is that hint refusal can be significantly reduced and learning can be significantly increased if Andes uses more unsolicited hints and meta hints. An unsolicited hint is a hint that is given without the student asking for one. A meta-hint is like an unsolicited hint in that it is given without the student asking for it, but it just prompts the student to click on the hint button. Two versions of Andes were compared: the original version and a new version that gave more unsolicited and meta-hints. During a two-hour experiment, there were large, statistically reliable differences in several performance measures suggesting that the new policy was more effective.

Description
The current study analyzed existing data, collected under a previous U.S. Department of Education Reading First grant, to investigate the strength of the relationship between scores on the first- through third-grade Dynamic Indicators of Basic Early Literacy Skills - Oral Reading Fluency (DIBELS-ORF) test and scores on a reading comprehension test (TerraNova-Reading) administered at the conclusion of second- and third-grade. Participants were sixty-five English Language Learners (ELLs) learning to read in a school district adjacent to the U.S.-Mexico border. DIBELS-ORF and TerraNova-Reading scores were provided by the school district, which administers the assessments in accordance with state and federal mandates to monitor early literacy skill development. Bivariate correlation results indicate moderate-to-strong positive correlations between DIBELS-ORF scores and TerraNova-Reading performance that strengthened between grades one and three. Results suggest that the concurrent relationship between oral reading fluency scores and performance on standardized and high-stakes measures of reading comprehension may be different among ELLs as compared to non-ELLs during first- and second-grade. However, by third-grade the correlations approximate those reported in previous non-ELL studies. This study also examined whether the Peabody Picture Vocabulary Test (PPVT), a receptive vocabulary measure, could explain any additional variance on second- and third-grade TerraNova-Reading performance beyond that explained by the DIBELS-ORF. The PPVT was individually administered by researchers collecting data under a Reading First research grant prior to the current study. Receptive vocabulary was found to be a strong predictor of reading comprehension among ELLs, and largely overshadowed the predictive ability of the DIBELS-ORF during first-grade. Results suggest that receptive vocabulary scores, used in conjunction with the DIBELS-ORF, may be useful for identifying beginning ELL readers who are at risk for third-grade reading failure as early as first-grade.

Description
The current study is a follow up to a previous evaluation of Believe It!, an internet-based career development program for adolescent girls. This study attempted to extend the program's effectiveness by manipulating animated agent appearance based on literature suggesting that agent appearance has implications for human-computer program interface. Participants included 52 Latinas (ages 11 to 14) randomly assigned to view one of two versions of the revised career program. Each version contained identical content but included animated agents designed to represent different ethnicities. Pre and post-treatment scores for three career belief measures and an occupational stereotype measure were analyzed using a MANCOVA. The results were not significant and further analyses revealed that the results were confounded by complications with the perceived ethnicity of the animated agents. Despite a lack of significance the results provide enriching information about Latina adolescent perception of ethnicity.
