A New Approach To Expectation Theory: Rationality Revisited, Tamas Forgacs

Masters Theses

Expectations play an important role in economics. Traditionally two major branches of expectation theory are distinguished: that of adaptive and rational expectations. This study sets out the goal of investigating inflationary expectations based on real world experiences. The model proposed and tested here abandons the traditional fixed-time-interval-update models for a non-fixed-time-interval-update model. Although the penalty function attached to each error is still subject to debate, it is shown that by reacting with faster updates to errors in expectations economic agents achieve more precise expectations compared to those of a fix time interval update model. We also find the model rational …

The Effects Of Field-Based Learning On The Knowledge, Behaviors And Practices Of Teachers And Students, Mary Jo Kosco

Masters Theses

The outdoor environment has the potential to serve as a teeming laboratory with numerous opportunities for students to study various science-related phenomena and processes. However important teachers deem outdoor experiences in science, they also bear doubts about their abilities to teach in these natural surroundings. Providing teachers with the training necessary to teach using field-based activities would help develop and strengthen the teachers' and consequently their students' interest in science, their background knowledge of basic science concepts and processes and possibly affect their behaviors towards the environment. This study was designed to measure the extent science teachers' field-based learning experiences …

These reacted silica gels were analyzed using diffuse reflectance infrared Fourier transform spectroscopy and ICP-AES elemental analysis. CH/Metal ratios were calculated using specific peaks in the IR spectra to elucidate the surface bonded species. Elemental analysis was used to determine how much metal was bonded …

Relations Of Explanatory Style, Learning Orientation, And Gender With Children's Academic Performance, Jennifer Grubar

Masters Theses

Several explanations have been offered to account for sex differences in academic achievement patterns. Two in particular have been looked at extensively in past research: learned helplessness/mastery orientation theory and attribution theory (explanatory style). Most studies look at these two explanations separately, but it seems important to examine them together. The present study explored how learning orientation, explanatory style and gender relate to children's academic performance.

The hypotheses of this study were that more girls would fall into the helpless category, but would still be optimistic and would have higher grade point averages (GPA' s). More boys were expected to …

Learning Disabilities: The Definitional Dilemma, Gretchen Burman

Masters Theses

As professionals in the fields of education and psychology, we often focus on the children who are having difficulty learning in and adjusting to school, children who may have learning disabilities. We examine test results and what they say about how a child learns; we consider what the teacher says about the difficulties the child has in the classroom. Teachers discuss how frustrating it is to work with children who are ''slow learners" or who "learn differently." However, the definition of learning disability is so variable that we may fail to identify, or we may over-identify, those with a learning …

Comparison Of Ability-Achievement Discrepancies Among The Wechsler Individual Achievement Test, Woodcock-Johnson-Revised Tests Of Achievement, And Wechsler Intelligence Scale For Children-Third Edition In A Sample Of Students Referred For Evaluation Of Learning Disabilities, Tracy L. Cole

Masters Theses

Under current IDEA definitions, a significant or severe discrepancy between intellectual ability and academic achievement is the primary criterion by which a student may be classified as having a specific learning disability. By recommendation of the Work Group on Measurement Issues in the Assessment of Learning Disabilities (1984), the most common method of determining such a discrepancy is to calculate the discrepancy between an individual's score on an individually administered intelligence test and his/her score on an individually administered achievement test using a regression-based formula to correct for the regression of IQ on achievement.

Because two previous studies suggested that …

Lithologic And Stratigraphic Analysis Of Glacial Diamictons, Sturgis, Michigan, R. Christopher Gardner

Masters Theses

Seven diamictons are identified in the subsurface glacial drift near Sturgis, Michigan using textural analyses and x-ray diffraction of clay minerals. The clay mineral content is quantified by comparing the 7-A/10- A peak height ratios from x-ray diffraction diffractograms of oriented clay-size particle (< 2um) mounts. Two diamictons occur at the base of the drift. Unit 1 is gray , resembling the shale it overlies. The texture of Unit 1 is sandy clay loam to loam and average 7-A/10-A peak height clay mineral ratios of 0.446 ±0.069. Unit 2 is a yellowish-brown diamicton, it overlies Unit 1, and is a sandy loam to loam with average 7-A/10-A clay mineral ratio of 0.657 ±0.151. Diamicton Units 4 and 5 overlie a thick unit of sand and gravel on top of Unit 2. Units 4 and 5 have similar color and texture, however the 7-A/10-A ratios are 1.059 ±0.090 and 0.810 ±0.072 respectively. Unit 6 is a thin diamicton unit, leached of calcite, and x-ray diffraction suggests that there is a range of weathering horzins between borings. Unit 7 is loamy, whereas Unit 8 generally ranges from sandy clay loam to sandy loam with average 7-A/10-A ratios of 0.865 ±0.090 and 1.195 ±0.189.
