Impacts of an Early Childhood Mathematics and Science Intervention on Teaching Practices and Child Outcomes

abstract

This randomized controlled trial examined effects of the MyTeachingPartner-Math/Science intervention on the quality and quantity of teachers’ mathematics and science instruction, and children’s mathematics and science outcomes in 140 pre-kindergarten classrooms. Teachers participated in the intervention for two years with consecutive cohorts of children. Results from Year 1 are considered experimental, however due to high levels of attrition, results from Year 2 are considered quasi-experimental. Across both years, intervention teachers exhibited higher quality and quantity of instruction. In Year 1, there were no significant effects of the intervention on children’s outcomes. In Year 2, children in intervention classrooms made greater gains in teachers’ ratings of mathematics and science skills and performed better on a spring assessment of science skills. These results have implications for designing and evaluating professional development aimed at supporting children’s mathematics and science knowledge and skills.

Using Blackboard in Library Instruction: Addressing the Learning Styles of Generations X and Y

Studies show that recent generations of college students have a learning style with identifiable characteristics. Library instruction efforts must adapt to these learning styles. Course management software (CMS), such as Blackboard, is one resource available to academic librarians to meet the challenges posed by the "Net Generation." At Stetson University, the use of Blackboard courseware in library instruction sessions successfully addressed the unique learning styles of students.     

ONE'S OWN TEACHER AND THE CHOICE OF THE TEACHING PROFESSION

Gustafsson, J.‐E. Differential Effects of Imagery Instructions on Pupils with Different Abilities. Scandinavian Journal of Educational Research, 21, 157‐179. A study investigating interactions between imagery instructions and aptitude variables is presented. A group of seven fifth‐grade classes was given imagery instructions in the reading of a short text, while another group read the text in a regular way. Three different outcomes covering different types of learning were registered. Tests of verbal ability and spatial (or imagery) ability were used as aptitude variables. The data analysis indicated that there were differences for the girls between the treatment groups among the aptitude variables; the results for the girls thus had to be excluded. A positive effect of imagery instructions was found for boys high in verbal and imagery ability with respect to the acquisition of simple terms. For other outcomes and groups of subjects either no effect or a negative effect was found.
