A Framework to Analyze Argumentative Knowledge Construction in Computer-Supported Collaborative Lear
Computer-supported collaborative learning (CSCL) is often based on written argumentative discourse of learners, who discuss their perspectives on a problem with the goal to acquire knowledge. Lately, CSCL research focuses on the facilitation of specific processes of argumentative knowledge construction, e.g., with computer-supported collaboration scripts. In order to refine process-oriented instructional support, such as scripts, we need to measure the influence of scripts on specific processes

Middle School Portal: Math and Science Pathways (MSP2)
This virtual manipulative offers two modes for examining the patterns of multiples found on a grid displaying the numbers 2-200. In one mode, the student clicks a number on the grid, turning it red and removing all multiples of the number from the grid. This process can be repeated until only prime numbers remain. In the other mode, the student highlights one or two numbers, with multiples of the first turning red and the second blue. In both modes, number patterns and relationships can be obser

Plaque behavior characteristics and regrowth of plaque in diseased arteries tissue during post-cryop
Atherosclerosis is a leading cause of heart diseases and mortality around the world. Recently cryoplasty has emerged as a potentially effective method to treat atherosclerosis. Finite element heat transfer and mass transfer models are developed in ANSYS in this study. The heat transfer model analyzes the heat transfer within the atherosclerotic plaque and arterial wall during the cryopalsty procedure. The model is useful in predicting the transient temperature through diseased wall tissues. The
Enhancing early literacy skills of pre-kindergarteners with histories of expressive phonological imp
Seven boys who had received intervention for highly unintelligible speech were tested for metaphonological awareness skills and alphabetic knowledge at the beginning of the summer prior to their entering kindergarten. Five of these boys participated in 12 small-group [2-hour] sessions that incorporated lessons from a comprehensive multisensory early literacy program. Two of the seven boys were not able to participate in the sessions because of summer activity conflicts. Post-treatment scores wer
Morphological variation of the proximal femur in selected skeletal remains
The purpose of this thesis is to examine the structural variation of the proximal femur in human skeletal samples. The goal was to investigate and further describe the morphology of the proximal femur through quantitative observation. Subsets of measurements were used to calculate platymeric indices, which demonstrate the presence or absence of platymeria in a population. Metric analyses of the femur were also used to study size and shape differences in populations for indications of sexual dimo
Evaluating cardiac gene expression in maternal phenylketonuria offspring
Maternal phenylketonuria (MPKU) is a teratogenic syndrome, caused by development of offspring in a uterine environment made toxic by the metabolic imbalance of PKU. The birth defects resulting from untreated MPKU include microcephaly with concomitant mental retardation, growth retardation, and congenital heart defects. Congenital heart defects have been identified and characterized in MPKU offspring, using the BTBR-PAHenu2 mouse MPKU model. Subsequently, this mouse model was used to start invest
Reassessment of intra- and extra-ovarian expression of growth differentiation factor-9
Mammalian ovarian organogenesis is characterized temporally by oogonial mitosis, oogonial apoptosis, rescue of germ cells via interaction with somatic cells to form primordial follicles, and entrance into meiosis. Recent studies suggest that germ cell’s activity participate in this process via the production of local regulatory factors. Growth differentiation factor-9 (GDF-9), a novel transforming growth factor-family member, is expressed in ovaries of various species as a crucial factor in ov
Characterization of mechanical systems with real joints and flexible links
The field of multibody simulations has seen great strides in recent years. Most multibody simulations are carried out under the assumption that the joints involved are ideal. However many real joints are not ideal; they possess some clearance between their components. The existence of these clearances allows for the freeflight motion of some of the joint’s constituent components. This motion is usually followed by an impact leading to load amplification and chaotic motion. The effects of impac
