Identi-beads and identi-badges as strategies to encourage STEM identity work

Broadening participation informal stem education

Carlone HB, Mercier A.
GSID: K5i9M3XqeLEJ
A Mercier, HB Carlone - Connected Science Learning, 2021 - nsta.org

At the end of a long day of STEM activities in the five-week Saturday Academies, six middle-school youth gather around a bag of multicolored plastic beads. Each colored bead represents a mode of STEM engagement (eg, pink represents investigator,...

Exploring teaching and course assistants' interventions with groups during collaborative problem-solving

Stem education interventions

Mercier E, Shehab S.
GSID: j7QyeWMj1MoJ
S Shehab, E Mercier - 2019 - repository.isls.org

This study explores the task-related interventions of a teaching assistant and three course assistants with six small groups during collaborative problem-solving activities in undergraduate engineering classrooms. Results indicated that the majority of the interventions were not preceded by monitoring...

Study and research courses as an epistemological model for didactics

Lewis acid behavior of SF4 : synthesis, characterization, and computational study of adducts of SF4 with pyridine and pyridine derivatives.

Chemistry (Weinheim an der Bergstrasse, Germany)

Chaudhary P, Goettel JT, Mercier HP, Sowlati-Hashjin S, Hazendonk P, Gerken M.
PMID: 25752662
Chemistry. 2015 Apr 13;21(16):6247-56. doi: 10.1002/chem.201406359. Epub 2015 Mar 06.

Sulfur tetrafluoride was shown to act as a Lewis acid towards organic nitrogen bases, such as pyridine, 2,6-dimethylpyridine, 4-methylpyridine, and 4-dimethylaminopyridine. The SF4 ⋅NC5 H5 , SF4 ⋅2,6-NC5 H3 (CH3 )2 , SF4 ⋅4-NC5 H4 (CH3 ), and SF4...

Nonlinear impedance of whole cells near an electrode as a probe of mitochondrial activity.

Biosensors

Palanisami A, Mercier GT, Fang J, Miller JH.
PMID: 25586827
Biosensors (Basel). 2011 Apr 11;1(2):46-57. doi: 10.3390/bios1020046.

By simultaneously measuring the bulk media and electrode interface voltages of a yeast (Saccharomyces cerevisiae) suspension subjected to an AC voltage, a yeast-dependent nonlinear response was found only near the current injection electrodes. Computer simulation of yeast near a...

Improved multimodal method for the acoustic propagation in waveguides with a wall impedance and a uniform flow.

Proceedings. Mathematical, physical, and engineering sciences

Mercier JF, Maurel A.
PMID: 27436978
Proc Math Phys Eng Sci. 2016 Jun;472(2190):20160094. doi: 10.1098/rspa.2016.0094.

We present an efficient multimodal method to describe the acoustic propagation in the presence of a uniform flow in a waveguide with locally a wall impedance treatment. The method relies on a variational formulation of the problem, which allows...

Trigonal Bipyramidal M(2)Ch(3)(2)(-) (M = Sn, Pb; Ch = S, Se, Te) and TlMTe(3)(3)(-) Anions: Multinuclear Magnetic Resonance, Raman Spectroscopic, and Theoretical Studies, and the X-ray Crystal Structures of (2,2,2-crypt-K(+))(3)TlPbTe(3)(3)(-).2en and (2,2,2-crypt-K(+))(2)Pb(2)Ch(3)(2)(-).0.5en (Ch = S, Se).

The series of group 14 metal trigonal bipyramidal anions has been extended to the mixed group 13/group 14 metal TlMTe(3)(3)(-) anions (M = Sn, Pb), obtained by the reaction of Tl(2)M(2)Te(3) and K(2)Te in en or in en/ethylamine mixtures...

Synthesis, characterization, and computational study of the trans-IO2F5(2-) anion.

Inorganic chemistry

The combination of CH(3)CN solutions of [N(CH(3))(4)][F] and a mixture of cis- and trans-[N(CH(3))(4)][IO(2)F(4)] produces the novel trans-IO(2)F(5)(2)(-) anion. Under the given conditions, only the trans-IO(2)F(4)(-) anion acts as a fluoride ion acceptor, thus allowing the separation of isomerically...
