We continue our investigation of the phenomenological implications ``deformed'' commutation relations $[{x}_{i},{p}_{j}]=i\ensuremath{\Elzxh}[(1+\ensuremath{\beta}{p}^{2}){\ensuremath{\delta}}_{\mathrm{ij}}+{\ensuremath{\beta}}^{\ensuremath{'}}{p}_{i}{p}_{j}].$ These are motivated by fact that they lead to minimal length uncertainty relation which appears in perturbative string theory. In this paper, we consider effects deformation on classical orbits particles a central force potential....
Abstract We describe three iterations of a Massive Open Online Course (MOOC) developed from online preparation materials for reformed introductory physics classroom at the Massachusetts Institute Technology, in which teaching staff interact with small groups students doing problems using an expert problem‐solving pedagogy. The MOOC contains e‐text, simple checkpoint and homework. show how certain course design aspects affect student behaviour: (a) frequent quizzes correlated reading large...
In previous studies we found that models with flavor-universal suppression of the neutrino-gauge couplings are compatible NuTeV and $Z$-pole data. this paper expand our analysis to obtain constraints on flavor-dependent coupling by including lepton universality data from $W$, $\ensuremath{\tau}$, $\ensuremath{\pi}$ $K$ decays in fits model parameters. We find consistent a variety patterns suppression. particular, scenarios which arises mixing light neutrinos heavy gauge singlet states...
We investigate how elements of course structure (i.e., the frequency assessments as well sequencing and weight resources) influence usage patterns electronic textbooks (e-texts) in introductory physics courses. Specifically, we analyze access logs courses at Michigan State University Massachusetts Institute Technology, each which deploy e-texts primary or secondary texts combination with different formative (e.g., embedded reading questions) summative assessment (exam) schedules. As such...
In a recent paper we pointed out that the mixing of light neutrinos with heavy gauge singlet states could reconcile Z-pole data from ${e}^{+}{e}^{\ensuremath{-}}$ colliders and ${\ensuremath{\nu}}_{\ensuremath{\mu}}({\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}})$ scattering NuTeV experiment at Fermilab. We further noted angle required to fit is much larger than what would be expected conventional seesaw mechanism. this paper, show how such mixings can arranged by judicious choice neutrino...

We investigate student-chosen, multi-level homework in our Integrated Learning Environment for Mechanics [1] built using the LON-CAPA [2] open-source learning system. Multi-level refers to problems categorized as easy, medium, and hard. Problem levels were determined a priori based on knowledge needed solve them [3]. analyze these three measures: time-per-problem, difficulty, item difficulty measured by response theory. Our analysis of student behavior this environment suggests that...
We are building in LON‐CAPA an integrated learning environment that will enable the development, dissemination and evaluation of PER‐based material. This features a collection multi‐level research‐based homework sets organized by topic cognitive complexity. These associated with modules contain very short exposition content supplemented open‐access videos, worked examples, simulations, tutorials (some from ANDES). To assess students' performance accurately respect to system‐wide standard, we...
We study the phenomenological implications of classical limit "stringy" commutation relations [x_i,p_j]=i hbar[(1+beta p^2) delta_{ij} + beta' p_i p_j]. In particular, we investigate "deformation" Kepler's third law and apply our result to rotation curves gas stars in spiral galaxies.
Strategic knowledge is required to appropriately organize procedures and concepts solve problems. We are developing a standardized instrument assessing strategic in the domain of introductory mechanics. This inspired part by Lawson's Classroom Test Scientific Reasoning Van Domelen's Problem Decomposition Diagnostic. The predictive validity has been suggested preliminary studies showing significant correlation with performance on final exams administered mechanics courses at Massachusetts...

Staff from edX, MIT, and Harvard will present two instructor dashboards for edX MOOCs. Current workflows be described, parsing displaying data to using course revision. A major focus lessons learned in the first years of deployment.
Abstract The integrated photonics and fiber optics industries are rapidly expanding innovating, respectively, to enable transformative new circuit, AI, datacom, wireless, sensing imaging systems for cloud mobile computing, automobile aircraft, display, medical, energy industries. This 21st century advanced manufacturing sector is in dire need of a massive increase its engineer technician workforce, over the next decade. To support this near-term workforce demand, modular library digital...
The emerging field of silicon photonics has created a large need for Ph.D. photonic integrated circuit design engineers. Developing intuition electromagnetic waves at the micron scale is major challenge facing undergraduate and graduate students in photonics. Students often misapply lessons learned from macroscale ray optics to submicron waveguide modes dielectric structures. In this work, key student misconceptions were identified addressed research study using training simulations. A...
The innovative breakthroughs of advanced manufacturing industries in materials processing and systems characterization are upgrading the incumbent engineer technician skillset a faster rate than ever before. This is creating an expanding gap between emerging STEM skills needed industry extant 4- or 2-year college training for engineers technicians, respectively. Novel teaching paradigms using MOOCs hybrid Learning formats have potential to address such gap. In this paper, we describe...
Engineering students in optics and photonics need robust intuitions for the micron-scale behavior of light dielectric materials. Educators often use textbook images ray diagrams static electric field profiles to introduce light, after which undergraduate graduate are expected run commercial software simulations explore dynamic waveguide modes. While incredibly powerful flexible, complex tools difficult novices use, preventing from gaining nuanced conceptual insights about optical components...
Despite the fact that a physics course typically culminates in one final grade for student, many instructors and researchers believe there are multiple skills students acquire to achieve mastery. Assessment validation data analysis general may thus benefit from extension multidimensional ability. This paper introduces an approach model determination dimensionality using collaborative filtering (CF), which is related factor item response theory (IRT). Model selection guided by machine...
