In the late 1800s and early 1900s, increases in metallurgic technology and better manufacturing methods made naval artillery a more powerful force. Guns could fire more powerful shells that could travel farther and hit a target with much greater accuracy. Torpedoes represented a major threat to even the most powerful of warships, forcing captains…

Debates about the future of UK language learning in the context of Brexit intensified as soon as the referendum outcome was announced. This politicization of language learning, evidenced recently also in the United States and France, falls upon an already difficult context of the United Kingdom in a 'language learning crisis,' and an increasing…

Reviewing the history of media literacy education might help us to identify how "creating media" as an approach can contribute to fostering knowledge, understanding technical issues, and to establishing a critical attitude towards technology and data. In a society where digital devices and services are omnipresent and decisions are…

The radioactive nature of technetium is discussed using a combination of introductory nuclear physics concepts and empirical trends observed in the chart of the nuclides and the periodic table of the elements. Trends such as the enhanced stability of nucleon pairs, magic numbers, and Mattauch's rule are described. The concepts of nuclear binding…

While performance assessment (PA) is well aligned to project-based learning (PjBL), teachers find it challenging to design and implement PA that is faithful to the authentic context of their projects and viewed externally as rigorous. In contrast to standardizing PA tasks--thereby diminishing authenticity--we formed a research-practice partnership…

While many colleges and universities are headed back to campus, providing multiple attendance options in an online or remote environment is key to student success. The name Attend Anywhere may be new, but the idea behind the name has been around for many years. It is often called HyFlex, but Attend Anywhere (AA) better describes how a student can…

The COVID-19 crisis upended the typical college experience as educational institutions had to close campuses and send students home mid-semester in the spring of 2020. The COVID-19 pandemic left educators around the world with limited choices on how to move forward with high quality education for all. This abrupt closing of higher education…

Molecular orbital configurations give rise to electronic terms comprising corresponding electronic states. Electronic terms possess symmetry classifications, which are denoted by a term symbol, based on the symmetry properties of the electronic wave functions associated with the states. Using the methylene radical, and both planar and twisted…

This paper reports a demonstration of a 90 min on-demand class where a chemical experiment is performed to educate nonscience majors on surfactants. First-year undergraduate students perform the water ball in a water bottle experiment at home and learn about the structure and properties of organic compounds in the demonstration. The experiment is…

Background: Several different measures have been proposed to solve persistent validity problems, such as high task-sampling variability, in the assessment of students' expertise in 'doing science'. Such measures include working with a-priori progression models, using standardised item shells and rating manuals, augmenting the number of tasks per…

Response to intervention (RTI) is a process used to identify academic, behavioral, and/or social-emotional supports for students with school related concerns. School counselors often serve on this team as supporters, interveners, advocates, and facilitators. English learners present unique language, access and identification challenges to RTI.…

Although school counselors participate in response to intervention (RTI), little research describes the unique opportunities and challenges encountered in RTI with English learners (ELs). This phenomenological study explored the experiences of school counselors engaging in RTI for ELs. The researchers identified three themes: (a) key stakeholders…

The paper applies a natural language computational tool to study a potential construct-irrelevant response strategy, namely the use of "shell language." Although the study is motivated by the impending increase in the volume of scoring of students responses from assessments to be developed in response to the Race to the Top initiative,…

The chemical elements present in the modern periodic table are arranged in terms of atomic numbers and chemical periodicity. Periodicity arises from quantum mechanical limitations on how many electrons can occupy various shells and subshells of an atom. The shell model of the atom predicts that a maximum of 2, 8, 18, and 32 electrons can occupy…

Nanoscience and technology research offer exciting avenues to modernize undergraduate-level General Chemistry curricula. In particular, spherical nucleic acid (SNA) nanoconjugates, which behave as "programmable atom equivalents" (PAEs) in the context of colloidal crystals, are one system that one can use to reinforce foundational…
