This study offers a holistic examination of 8 grade student performance in mathematics in schools in Botswana based on the country’s sample data from the IEA’s Trends in International Mathematics and Science Study (TIMSS) of 2003. The analyzed sample is comprised of 4,805 students in 136 schools. Missing data was treated at the student level using multiple imputation and at the school level usi...

This study investigated adolescents’ developmental trajectories of mathematics interest and explored related effects of gender, family, and school context. Latent growth curve modeling was used to analyze longitudinal data of N 3,193 students (51% female) from grades 5 to 9 from all 3 ability tracks of the German state school system. Annual assessments involved student ques tionnaires on intere...

Science and mathematics are becoming computational endeavors. This fact is reflected in the recently released Next Generation Science Standards and the decision to include ‘‘computational thinking’’ as a core scientific practice. With this addition, and the increased presence of computation in mathematics and scientific contexts, a new urgency has come to the challenge of defining computational...

Constructing smooth freeform surfaces of arbitrary topology with higher order continuity is one of the most fundamental problems in shape and solid modeling. Most real-world surfaces are with negative Euler characteristic number χ = 2 − 2g − b < 0, where g is genus, b is the number of boundaries. This paper articulates a novel method to construct C∞ smooth surfaces with negative Euler numbers b...

Constructing smooth freeform surfaces of arbitrary topology with higher order continuity is one of the most fundamental problems in shape and solid modeling. Most real-world surfaces are with negative Euler characteristic χ < 0. This paper articulates a novel method to construct C∞ smooth surfaces with negative Euler numbers based on hyperbolic geometry and discrete curvature flow. According to...

The purpose of this correlational research was to examine the relationship between achievement emotions, motivation, and classroom engagement in mathematics among Turkish middle school students, determine how these three variables predicted academic mathematics. 549 seventh grade students a province located south-west region Turkey participated study. Relations were examined by utilizing struct...

My research is at the interface between applied mathematics and climate atmosphere ocean science. My primary applied mathematics research interests are in geometrical data analysis algorithms and statistical modeling of dynamical systems. These tools are applied in a range of applications in climate science, including intraseasonal oscillations of organized tropical convection and arctic sea-ic...
