The Math Center is a noncredit, Community Education class which provides assistance in mathematics as a completely free service. Current Allan Hancock College students as well as other individuals who are 18 years or older may register for the Math Center each semester and take part in the following services as frequently as they want:

50. Are there instructional considerations required for grouping students in a special class?

Yes. Students with disabilities grouped together for purposes of instruction must be grouped in consideration of similarity of needs, including the levels of knowledge and development in subject and skill areas, (e.g., activities of daily living, level of intellectual functioning, adaptive behavior, expected rate of progress in acquiring skills and information, and learning style). The range of academic or educational achievement of such students must be limited to assure that instruction provides each student appropriate opportunities to achieve his or her annual goals. For students placed in a special class, except for a 12:1+ (3:1) special class, where the range of achievement levels in reading and mathematics exceeds three years, special notification to the CSE and parents must be provided. The learning characteristics of students in the group must be sufficiently similar to assure that this range of academic or educational achievement is at least maintained (i.e., no students fall behind in academic achievement because their instructional needs are not being addressed due to the range of learning characteristics of students in the class).

In response, some researchers and public officials have argued that, while gender differences have disappeared in average mathematics ability (i.e., the middle of the distribution), men nevertheless remain overrepresented as high-performers (i.e., right-tail of the distribution) (Ceci et al., 2014). On the one hand, nationally representative samples indeed reveal slight but consistent advantages for boys on standardized math tests, with a 2:1 overrepresentation among math high-performers from kindergarten (Penner and Paret, 2008) to grade 7 (Wai et al., 2010). On the other hand, these same studies reveal that the gender gap in high-performers has closed rapidly over time, moving from 13.5:1 in the 1980s, to 3.8:1 in the 1990s, to 2:1 today (Penner and Paret, 2007; Wai et al., 2010). This rapid closing of the gap on both average and high-performing math ability (Wai et al., 2010; Hyde, 2014) challenges the assumption that differences are rooted in immutable traits.

We consider quasi-stationary (travelling wave type) solutions to a nonlinear reaction-diffusion equation with arbitrary, autonomous coefficients, describing the evolution of glioblastomas, aggressive primary brain tumors that are characterized by extensive infiltration into the brain and are highly resistant to treatment. The second order nonlinear equation describing the glioblastoma growth through travelling waves can be reduced to a first order Abel type equation. By using the integrability conditions for the Abel equation several classes of exact travelling wave solutions of the general reaction-diffusion equation that describes glioblastoma growth are obtained, corresponding to different forms of the product of the diffusion and reaction functions. The solutions are obtained by using the Chiellini lemma and the Lemke transformation, respectively, and the corresponding equations represent generalizations of the classical Fisher-Kolmogorov equation. The biological implications of two classes of solutions are also investigated by using both numerical and semi-analytical methods for realistic values of the biological parameters. 2351a5e196
