Assessment in a Common Core Era: Revolutionary or Evolutionary?
Creators: name: Dimacali, Allen M.
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2012

description: In conjunction with the adoption and subsequent implementation of the Common Core State Standards for Mathematics (CCSSM), state-led consortia are developing next-generation assessments aligned to the CCSSM. This paper discusses the progress and plans of two main coalitions of states—the Partnership for Assessment of Readiness for College and Careers (PARCC) and the SMARTER Balanced Assessment Consortium (SBAC)— as they work to develop new and innovative assessments to measure the CCSSM and replace current state assessments. They attempt to integrate into each of their assessment systems various facets of testing (e.g., online administration, computer adaptive testing, performance-based tasks) already in existence. What is proposed to be revolutionary and innovative in testing appears more like the next evolutionary step in assessment. Scheduled for full implementation in 2014–2015, what remains to be seen is whether these assessments can accomplish two goals: (1) close the gap with NAEP and (2) replace college placement tests.

Assessment of Mathematical Modeling
Creators: name: Leong, Ronny Kwan Eu
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2012

description: Modeling is now being given prominence as one of the six high school subject areas in the Standards for Mathematical Content in the Common Core State Standards for Mathematics (CCSSM). The CCSSM document suggests that mathematical modeling should not be taught as an isolated topic but instead should be employed along with other topics. The essence of a modeling problem is constructing a mathematical model for the situation at hand. Assessing mathematical modeling is a new field that requires more study. Developing more tools and ideas to assess modeling tasks is essential and beneficial for mathematics teachers. Rubrics that assess the modeling process are a good beginning in finding suitable methods of assessing mathematical modeling. This article provides two methods for assessing modeling tasks. The first is a scoring rubric that is based on the process of CCSSM’s modeling cycle while the second instrument intends to assess the affective domain of mathematical modeling.

Simulation of jet installation effects at Mach=0.9: influence of numerical methodology and physical insights
Creators: name: Huet, Maxime
Publisher: name: Zenodo
Year: 2023

description: The noise radiated by an isothermal, single-stream jet with a Mach number M=0.9 and diameter-based Reynolds number ReD = 106 is investigated numerically without and with the presence of a flat plate. Noise sources are predicted with Zonal Detached Eddy Simulations mode 3 together with turbulence tripping inside the nozzle to recover an initially turbulent flow, while radiated pressure is extrapolated with integral methods. Numerical methodology, namely grid and statistical convergence of the signals, is assessed for the isolated jet. Noise levels are accurately simulated at least up to St = 8 and integrated pressure levels collapse within 1 dB with the experiments. In the presence of the plate, an innovative noise radiation methodology based on integral methods is proposed to reconstruct the pressure signals at microphone locations with a reduced numerical cost. The simulation compares very favorably with the experimental data, azimuthal noise variations induced by the plate are correctly captured and noise levels collapse within 1 dB. It is concluded the numerical methodology is mature enough for application in an industrial context.

Year: 2012

description: The Common Core State Standards for Mathematics presents challenges and opportunities to contribute to a common understanding of the mathematical proficiencies expected of our students. This paper discusses the movement to establish multi-state assessment consortia in the United States based in the standards movement set in motion by the National Council of Teachers of Mathematics and the increased accountability of student learning through the No Child Left Behind Act. The consortia intend to assess the full range of student learning expectations to include both standards for mathematical content and mathematical practices through construction of comprehensive systems of assessments that accurately measure student progress toward college and career readiness. The systems are to include interim and summative assessments primarily taken in an online environment that allows for automated or timely scoring.

description: We have measured the sub-milli-arcsecond structure of 274 extragalactic sources at 24 and 43 GHz in order to assess their astrometric suitability for use in a high frequency celestial reference frame (CRF). Ten sessions of observations with the Very Long Baseline Array have been conducted over the course of $\sim$5 years, with a total of 1339 images produced for the 274 sources. There are several quantities that can be used to characterize the impact of intrinsic source structure on astrometric observations including the source flux density, the flux density variability, the source structure index, the source compactness, and the compactness variability. A detailed analysis of these imaging quantities shows that (1) our selection of compact sources from 8.4 GHz catalogs yielded sources with flux densities, averaged over the sessions in which each source was observed, of about 1 Jy at both 24 and 43 GHz, (2) on average the source flux densities at 24 GHz varied by 20%-25% relative to their mean values, with variations in the session-to-session flux density scale being less than 10%, (3) sources were found to be more compact with less intrinsic structure at higher frequencies, and (4) variations of the core radio emission relative to the total flux density of the source are less than 8% on average at 24 GHz. We conclude that the reduction in the effects due to source structure gained by observing at higher frequencies will result in an improved CRF and a pool of high-quality fiducial reference points for use in spacecraft navigation over the next decade.

Relaxation dynamics in a molecular ultracold plasma : control and modeling
Creators: name: Wang, Ruoxi
Publisher: name: University of British Columbia
Year: 2023

description: In many-body systems out-of-equilibrium, strong coupling triggers emergent properties that can act to limit the natural dissipation of energy and matter. The physics of strong coupling plays an important but incompletely understood role in the dynamics of natural plasmas over a wide range of length scales. Particularly remarkable signs of hindered transport appear under laboratory conditions in the self-organized avalanche, bifurcation, and quench of the nitric oxide molecular ultracold plasma. Here, a UV-UV double-resonant excitation of nitric oxide, cooled to 500 mK in a skimmed supersonic molecular beam prepares an ellipsoidal Rydberg gas of known initial density in a single selected state of principal quantum number, n₀. Penning ionization, followed by an avalanche of electron-Rydberg collisions, forms a plasma of NO⁺ ions and weakly bound electrons, in which a residual population of n₀ Rydberg molecules evolves to a state of high orbital angular momentum, ℓ. A 60 MHz radio frequency pulse with a peak-to-peak amplitude as low as 400 mV/cm, applied to a plasma in a state of arrested relaxation, depletes the residual Rydberg signal. Similarly, mm-wave fields in the range from 70 to 100 GHz tuned to resonance with n₀f (2)→(n₀ ±1)d(2) transitions deplete the plasma signal to an amplitude near zero. We associate both effects with Rydberg electronic orbital angular momentum redistribution. New theoretical work has developed a primitive picture of this system using a Lindblad master equation to describe the Markovian dynamics that arise when a closed quantum system of disordered, randomly interacting molecular dipoles couples to a thermal continuum of free atoms.

Estimating the Gumbel scale parameter for local alignment of random sequences by importance sampling with stopping times

description: The gapped local alignment score of two random sequences follows a Gumbel distribution. If computers could estimate the parameters of the Gumbel distribution within one second, the use of arbitrary alignment scoring schemes could increase the sensitivity of searching biological sequence databases over the web. Accordingly, this article gives a novel equation for the scale parameter of the relevant Gumbel distribution. We speculate that the equation is exact, although present numerical evidence is limited. The equation involves ascending ladder variates in the global alignment of random sequences. In global alignment simulations, the ladder variates yield stopping times specifying random sequence lengths. Because of the random lengths, and because our trial distribution for importance sampling occurs on a different sample space from our target distribution, our study led to a mapping theorem, which led naturally in turn to an efficient dynamic programming algorithm for the importance sampling weights. Numerical studies using several popular alignment scoring schemes then examined the efficiency and accuracy of the resulting simulations.

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: The paper presents an analytical description of the growth of a two-component bubble in a binary liquid-gas solution. We obtain asymptotic self-similar time dependence of the bubble radius and analytical expressions for the non-steady profiles of dissolved gases around the bubble. We show that the necessary condition for the self-similar regime of bubble growth is the constant, steady-state composition of the bubble. The equation for the steady-state composition is obtained. We reveal the dependence of the steady-state composition on the solubility laws of the bubble components. Besides, the universal, independent from the solubility laws, expressions for the steady-state composition are obtained for the case of strong supersaturations, which are typical for the homogeneous nucleation of a bubble.

Moreover, the integral case is discussed and we determine the operations $K^M_i/p \to K^M_j/p$ for smooth schemes over a field.

Assessment for the Common Core Mathematics Standards
Creators: name: Wu, Hung-Hsi
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2012

description: This article makes two simple observations about high-stakes assessments. The first is that, because mathematics is a very technical subject, an assessment item can be mathematically flawed regardless of how elementary it is. For this reason, every assessment project needs the active participation of high level mathematicians. A second point is that high-stakes assessments are inherently a very blunt instrument because they are incapable of accurately measuring the most important aspect of mathematics achievement: sustained sequential thinking. Because the general public and policy makers are not aware of this fact, they tend to read more into such assessment scores than such a limited instrument can deliver. If we want high-stakes assessments to have a positive influence on mathematics education, this article suggests that we should reorient our thinking about how much student achievement such assessments can reliably measure, which is “not very much.”

description: This exploratory study compared a computer-based mathematics education intervention with two more traditional approaches with the purpose of improving instruction in perimeter and area. Kidspiration software, tile/stick manipulatives and pencil/paper-based copying/drawing of shapes were implemented in a 3rd Grade New York City public school classroom. This study demonstrated student improvement across the three interventions when comparing pre-intervention and post-intervention test scores. Students who engaged with the copying/drawing shapes intervention demonstrated the greatest test score improvement after the intervention, those who used Kidspiration ranked second and tile/stick manipulatives were third. When queried about their perceptions of the efficacy of these interventions, students generally perceived all three of the interventions as being positive in improving their learning of perimeter and area. Developing new methods to address deficiencies in current forms of assessment that would highlight the benefits of non-traditional forms of education, such as technological initiatives, is recommended.

description: Interactive Whiteboards (IWBs) are becoming commonplace throughout primary, secondary, and post- secondary classrooms. However, the focus of the associated lesson creation & management software tools delivered with IWBs has been the primary grades, while secondary and postsecondary mathematics lessons have requirements beyond what is delivered entirely within this software. This article describes how SMART NotebookTM, the software delivered with SMART Technologies’ SMART BoardTM, allows teachers to easily go beyond any perceived limitations by facilitating integration of a wide variety of other software packages to produce dynamic, visually appealing, and most important, effective calculus lessons. The content and visual requirements of such lessons are described and examples from actual lessons demonstrate how these requirements can be fulfilled.

Math Is Not a Spectator Sport: The Effect of Online Homework-Completion Tutoring On Community College Remedial Mathematics Performance
Creators: name: Cunningham, Alice W.

name: Angulo, Nieves
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2011

description: This article analyzes the findings from an 18-section experiment studying the effect of homework-completion tutoring on community college students’ remedial mathematics performance. The experiment involved 529 students registered for two remedial math courses: math skills and algebra. For each course, the experiment studied nine sections: three experimental with multiple tutors for online homework, three control with a single tutor for online homework, and three control with a single tutor for pencil-and-paper exercises. While state budget constraints delayed the availability of tutors for the experimental group until midway through the semester, that group outperformed the pencil-and-paper group at a 0.05 significance level, while the performance of the online homework control group categories surpassed those of the corresponding pencil-and-paper categories at up to a 0.001 significance level. In addition, for each course, math lab attendance for both the experimental and control online homework cohorts surpassed that of the pencil-and-paper cohorts. These results corroborate and extend earlier research and show the importance of active problem-solving rather than passive absorption in increasing remedial mathematics performance.

description: Developing curriculum and instruction for mathematics education and designing technologically enhanced learning environments are often pursued separately, but may need to be addressed together to effectively link the strengths of technology to performance in mathematics and conceptual understanding. This paper addresses current challenges with educational technology in elementary and middle school mathematics education, as well as technology’s influence on curriculum, instruction, and student performance. Three properties of computer-based technology are described; these properties determine technology’s unique value for elementary and middle school mathematics: engagement and motivation, informative feedback, and visualization. Three computer-based math applications, Doodle Math, Puzzle Me, and GeoShape, are introduced as examples that combine effective learning resources and technology.

Year: 2011

description: Video games have tremendous potential in mathematics education, yet there is a push to simply add mathematics to a video game without regard to whether the game structure suits the mathematics, and without regard to the level of mathematical thought being learned in the game. Are students practicing facts, or are they problem-solving? This paper examines several schema for assessing how the structure of a video game interacts with the mathematical content. The schema include whether the mathematics is intrinsic to the structure of the game, and whether the game is epistemic, that is, whether players take on the identity of a mathematician or problem-solver while playing. Implications for future video games are discussed.

After recounting some of the mathematical tools that led to a better understanding of celestial change, an analogous approach is used to address terrestrial change here on earth. This involves an incisive look at Fibonacci's rabbit problem and leads to the consideration of “a Copernican metaphor,” one in which efforts to address environmental issues are related to the transition from a geocentric to heliocentric model of the solar system.

Tech@MoMath: Technology Use in the Forthcoming Museum of Mathematics
Creators: name: Gould, Heather
name: Reimer, Catherine
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2011

description: In the late Fall of 2012, the Museum of Mathematics (“MoMath”) will open in New York City and will be the only museum dedicated solely to mathematics in the United States. The content and design of most of the exhibits are not yet available to the public but some information about how the Museum will use technology has been released. The ways that the Museum makes use of technology can be classified into two categories: those that increase accessibility and those that increase exposure. The specific technologies used within both categories are discussed in the context of their pedagogical value. Teachers then are introduced to some ways that they can adapt MoMath’s technology use to their own classrooms.

The Frame Game
Creators: name: Edwards, Michael Todd
name: Cox, Dana C.
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2011

description: In this article, the authors explore framing, a non-multiplicative technique commonly employed by students as they construct similar shapes. When students frame, they add (or subtract) a “border” of fixed width about a geometric object. Although the approach does not yield similar shapes in general, the mathematical underpinnings of framing are noteworthy. Using Interactive Geometry Software (IGS), teachers can explore mathematics behind the framing technique in greater depth while addressing student misconceptions and over- generalizations associated with the approach in classroom settings.

Year: 2011

description: The project reported here is conducting repeated randomized control trials of an approach to high school geometry that utilizes Dynamic Geometry (DG) software to supplement ordinary instructional practices. It compares effects of that intervention with standard instruction that does not make use of computer drawing/exploration tools. The basic hypothesis of the study is that use of DG software to engage students in constructing mathematical ideas through active investigations results in better geometry learning for most students. The study tests that hypothesis by assessing student learning in classrooms randomly assigned to treatment and control groups. The project is currently in its second year, and has just completed its first implementation of the DG approach, related data collection, and some initial data analysis. HLM models showed that the treatment group significantly outperformed the control group in geometry achievement. While the effect of the DG treatment is of moderate size for all participating students the largest effect size occurs with students in Regular Geometry classes.

title: Improving Comprehension for Students with Learning Disabilities Using The Comprehension Improvement Strategy
Creators: name: Payne, Ryun
Publisher: name: Utah State University

description: Students with learning disabilities generally have a difficult time meeting all of the course deadlines and gaining necessary skills in each of their rigorous high school courses. There are students who have difficulty showing what they learn and completing all the requirements for each class. For many years, there have been teachers that have looked for the best ways to instruct students and give them the tools they need to find success. There have been some strategies that have worked through the years and proved to be a great benefit for the students. There are other strategies that must be revamped and updated to fit the diverse needs of the 21st century learner. In order for students to be successful, one must ask if the learning strategy is effective for students and the teacher and whether the strategy can be implemented by students in practical situations. The main goal of this creative project was to determine if the implementation of the Comprehension Improvement Strategy in a reading prompt would improve students’ reading comprehension. To answer this question, data were collected for the number of accurate synonyms generated and the number of correctly answered comprehension questions answered. When synonyms were used within a reading prompt, the objective was for students to begin to put information together and enhance comprehension. However, the data suggest that this was not always the case for all students- while use of synonyms increased for some students, the number of correctly answered comprehension questions did not.

description: The acoustic nucleation threshold for bubbles trapped in cavities has theoretically been predicted within the crevice theory by Atchley & Prosperetti [J. Acoust. Soc. Am. 86, 1065-1084 (1989)]. Here, we determine this threshold experimentally, by applying a single pressure pulse to bubbles trapped in cylindrical nanoscopic pits ("artificial crevices") with radii down to 50 nm. By decreasing the minimum pressure stepwise, we observe the threshold for which the bubbles start to nucleate. The experimental results are quantitatively in excellent agreement with the theoretical predictions of Atchley & Prosperetti. In addition, we provide the mechanism which explains the deactivation of cavitation nuclei: gas diffusion together with an aspherical bubble collapse. Finally, we present superhydrophobic nuclei which cannot be deactivated, unless with a high-speed liquid jet directed into the pit.

description: Observations of the temperature anisotropies induced as light from the CMB passes through large scale structures in the late universe are a sensitive probe of the interactions of photons in such environments. In extensions of the Standard Model which give rise to mini-charged particles, photons propagating through transverse magnetic fields can be lost to pair production of such particles. Such a decrement in the photon flux would occur as photons from the CMB traverse the magnetic fields of galaxy clusters. Therefore late time CMB anisotropies can be used to constrain the properties of mini-charged particles. We outline how this test is constructed, and present new constraints on mini-charged particles from observations of the Sunyaev-Zel'dovich effect in the Coma cluster.

Novel activity assay development for soluble T-cell activators in bioprocessing

Publisher: name: University of British Columbia

description: Chimeric antigen receptor (CAR) T-cell therapy has emerged as a highly promising cell-based approach for the treatment of cancers. A key initial step in biomanufacturing is for T-cells to be activated before their transduction so as to promote their transfection and proliferation into high yields of CAR T-cells. Soluble activators provide an attractive alternative for biomanufacturing since they eliminate the cell losses when magnetic beads are removed, and this also simplifies bioprocessing. However, understanding the soluble activator exposures of human T-cells is a potential critical process parameter in the biomanufacturing of CAR T-cells. As alternative functional assays were assessed, it was found that upon activation, a major change in cell size was observed long before the cell numbers increased. Thus, a functional assay to measure the activity in culture supernates was developed based on measurements of T-cell diameters. Image analysis was used to measure the sizes of T-cells after 24, 48, or 72 hours of culture to determine the duration that most effectively distinguished variable activity levels. This activity assay was then used to determine the soluble activator levels over time, as well as to distinguish mechanisms of activity loss caused by binding to culture vessel surfaces, thermal degradation, or cell binding/internalization. The cell binding/internalization was by far the greatest contributor to activity decreases. Thus, this assay provides a means to monitor a key variable so as to increase the process understanding of CAR T-cell biomanufacturing. Additionally, the feasibility of refreezing many small T-cell aliquots with an acceptable recovery rate was demonstrated.
Mathematical Visualization

description: Advances in computer graphics have provided mathematicians with the ability to create stunning visualizations, both to gain insight and to help demonstrate the beauty of mathematics to others. As educators these tools can be particularly important as we search for ways to work with students raised with constant visual stimulation, from video games to MTV. Computer generated images, animations and interactive demonstrations permeate all areas of mathematics education, making it important for educators and researchers to determine how best to harness these tools to increase student learning. This survey article discusses what we know, and do not know, about creating effective visualizations and describes possible avenues for future work in the area.
