“Let’s Review.” A Look at the Effects of Re-teaching Basic Mathematic Skills

In this action research study of my classroom of 8th grade mathematics, I investigated the effect of reviewing basic fraction and decimal skills on student achievement and student readiness for freshman Algebra. I also investigated the effect on the quality of student work, with regards to legibility by having students grade each other’s work anonymously. I discovered that students need basic skill review with fractions and decimals, and by the end of the research their scores improved. However, their handwriting had not. At the end of the research, a majority of the students felt the review was important, and they were ready to take math next year in high school. As a result of this research, I plan to implement weekly fraction and decimal review assignments in all middle school grades: 6th, 7th, and 8th. In addition, fraction and decimals must be incorporated into daily assignments, where appropriate, in order to encourage students to retain these skills.

Memorial Stadium: Expansion, Renovation, Addition

The Memorial Stadium project will investigate the current conditions of facilities, study existing programs with regard to renovation and modification, and establish capacities for expansion. The project necessitates knowledge of sports facilities and the specific needs of the football program. This may involve research into the need of individuals ranging from the players themselves to the coaches, and ultimately the fans as well. The result will lead to a program which provides excellent solutions to the found needs. It is assumed that these needs will include updated training, locker room, and medical facilities for the athletes. Other programs include offices and meeting rooms for coaches, additional seating for fans—raising overall seating capacity of Memorial Stadium, as well as the possible addition of luxury skyboxes. Existing spaces will be scrutinized and renovation options will be explored. Programs may be changed or moved within the existing stadium spaces. Study will uncover the most feasible and reasonable solutions to programming spaces within the stadiums current facilities. This project will seek to connect the architecture of a stadium with the experience of the game. The design of athletic facilities and the addition of seating will embody the tradition of winning and the excitement of the future for Nebraska Football in Memorial Stadium. Mark Hoistad, mentor.

Effects of addition of a bird repellent to fish diets on their growth and bioaccumulation

The effects of adding the nonlethal bird repellent methyl anthranilate (MA), at levels of 100 and 1000 mg/kg, to fish feed on the bioaccumulation and growth of juvenile (10 g) hybrid striped bass (Morone chrysops x M. saxatilis) and juvenile (1g) African cichlid fish Aulonocara jacobfreibergi were investigated under laboratory conditions. The bird repellent did not have any effect on the fish growth or survival over a period of 6 weeks. MA residues at low levels of 11.2 ± 2.6 mg/g were found in lipophilic tissues (liver) of MA-fed fish. Control fish, which had no MA added to their diet, had a much lower level of 0.6 ± 0.3 mg/g MA in their liver. Fish muscle was found to contain negligible MA residues, while the outer body surface mucus did not contain any MA. Following a 6-week depuration period, during which the previously MA-fed hybrid striped bass were fed a feed to which no MA was added, the levels of MA residues detected were reduced by one order of magnitude.
