“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.

Stochastic Partial Budgeting: A New Look at an Old Tool

Farm business managers are constantly making adjustments in their businesses for smoother operations and profitability. Many times, these choices involve actions to enhance the financial return of the farm business; while other times these decisions are made out of necessity to minimize the effects of unfavorable conditions or events such as drought or changes in the market conditions. Some of these decisions are relatively simple, requiring making choices among alternatives within an enterprise; while others are complex involving a total overhaul of the business and its enterprises. Alternative choices within an individual enterprise can have a differential impact on farm profitability. Therefore, making the best decision may make the difference between profit or loss for that enterprise. Partial budgeting is very useful in making such changes within an enterprise of a farm.

Children’s Play in Cross-Cultural Perspective: A New Look at the Six Cultures Study

A qualitative and quantitative reanalysis of the Six Cultures data on children’s play, collected in the 1950s, was performed to revisit worlds of childhood during a time when sample communities were more isolated from mass markets and media than they are today. A count was performed of children aged 3 to 10 in each community sample scored as engaging in creative-constructive play, fantasy play, role play, and games with rules. Children from Nyansongo and Khalapur scored lowest overall, those from Tarong and Juxtlahuaca scored intermediate, and those from Taira and Orchard Town scored highest. Cultural norms and opportunities determined how the kinds of play were stimulated by the physical and social environments (e.g., whether adults encouraged work versus play, whether children had freedom for exploration and motivation to practice adult roles through play, and whether the environment provided easy access to models and materials for creative and constructive play).
