The Impact of Speedometry on Student Knowledge,Interest, and Emotions

Given the dearth of high-quality curriculum materials aligned with the new standards (NGSS and CCSS) and low student persistence in STEM fields, we sought to develop and test a STEM curriculum that would improve student knowledge, interest, and emotions. A cluster randomized control trial was conducted to assess the impact of Speedometry, a two-unit STEM curriculum that uses familiar toy cars to explore math and science concepts. A total of 1,615 fourth-grade students across 48 classrooms and 17 schools in an urban district participated in the study. Using a 3-level multilevel model (students nested within teachers and schools) and controls for student and teacher characteristics, we found that Speedometry led to significant increases in student knowledge and positive emotions such as excitement. Speedometry also led to significant decreases in negative emotions such as boredom, frustration, and confusion. The curriculum was implemented with high fidelity as evidenced by classroom observations and teacher self-reports.     

The occurrence of analogies in elementary school science books

An analogy is a model drawn from one contextand used to support understanding in anothercontext. This study investigates the extent towhich analogies in instructional science booksare provided by authors. The books surveyed areavailable from commercial suppliers andintended for use in the elementary schoolclassroom with 7 to 11 year old children.Eighty texts were analysed for the presence orabsence of analogies. Forty-five of the booksoffered no analogies at all. In the remainingthirty-five books, 92 analogies were found.These were classified in line with earlier workon analogies for older students by Curtis andReigeluth (1984) and the findings arediscussed. The extent to which teachers candraw upon the analogies in such texts tosupport children's understanding isconsidered.     

Contrasting landscapes: A comparison of the impact of different induction programs on beginning secondary science teachers' practices,beliefs, and experiences

Induction programs are essential in addressing the unique pedagogical and content needs of secondary science teachers. Yet most secondary science teachers have little access to general induction programs, and even less opportunity to participate in specialized science induction programs. This study examines the impact of three different induction programs on secondary science teachers. The teachers were matched by grade level among three groups; one group participated in a science‐focused support program, another participated in a general support program, and a third had no formal support. All teachers were monitored during the spring semester to understand their teaching beliefs, instructional practices, and experiences in the classroom. The analysis of data revealed that the secondary science teachers in the science‐focused support program implemented more student‐centered inquiry lessons, held beliefs aligned with student‐centered practices, and felt fewer constraints in their teaching than did the other two groups of teachers. This study reinforces the importance of induction programs for teachers, suggests there is a need for specialized support programs for beginning science teachers, and recommends that universities and school districts work together to develop such programs. © 2003 Wiley Periodicals, Inc.

Observed peer victimization during early elementary school: continuity, growth, and relation to risk for child antisocial and depressive behavior

The rate at which 266 boys and girls ages 5 to 7 years old were victimized by peers was observed on multiple occasions in kindergarten and first grade. Individual differences in victimization were observed at kindergarten entry and in growth over the subsequent 2 years. Victimization increased for some children but decreased for others. Growth in victimization was reciprocally related to growth in teacher-reported antisocial and depressive behavior for boys. For girls, kindergarten victimization was related to growth in parent-reported antisocial behavior, teacher-reported depressive behavior to growth in victimization, and growth in victimization to parent-reported depression. At a short-term group level, antisocial behavior had a lagged suppressive effect on victimization for boys but a facilitating effect for girls.
