To understand relationships between students' fractional knowledge and algebraic reasoning in the domain of equation writing, an interview study was conducted with 12 secondary school students, 6 students operating each 2 different multiplicative concepts. These concepts are based on how coordinate composite units. Students participated two 45-minute interviews completed a written fractions assessment. second concept had not constructed numbers, but third had; represented multiplicatively...
The purpose of the study was to investigate how Lesson Study influences pre-service teachers' learning professionally notice students' mathematical thinking. initial and last video-recorded discussions were analysed using a qualitative method. Findings suggest that can be useful means improve noticing expertise in reviewing planning lessons. However, maximise effect on developing expertise, several modifications need made protocol, which are discussed.
Switchgrass (Panicum virgatum L.) is a promising perennial bioenergy crop that achieves high yields with relatively low nutrient and energy inputs. Modification of cell wall composition for reduced recalcitrance can lower the costs deconstructing biomass to fermentable sugars other intermediates. We have engineered overexpression OsAT10, encoding rice BAHD acyltransferase QsuB, dehydroshikimate dehydratase from Corynebacterium glutamicum, enhance saccharification efficiency in switchgrass....
Because teachers cannot directly access the processes by which students construct their mathematical knowledge, Teacher Noticing, an activity that involves observing students' work, interpreting thinking about a task based on remarks or actions, and responding to thinking, is important grasp understanding. A possible way for develop noticing expertise engage in situation focused student such as clinical interviews. However, productively through interviews remains challenge, especially...
In this study, we investigated how elementary pre-service teachers (PSTs) perceive using representations in teaching mathematics and what fractional (e.g., manipulatives or models) they suggest to guide students' incorrect use of learning fractions. A written questionnaire was administrated 151 PSTs at a large Southwestern university the US. An inductive content analysis approach including both qualitative quantitative analyses used analyze data. Findings suggested that fraction-related...
ABSTRACT Soluble chemically reduced graphene oxide (RGO)/poly(4‐vinyl pyridine) (P4VP) assembly was attempted by totally noncovalent approach. Chemical reduction of P4VP/GO mixture hydrazine produced soluble RGO/P4VP with long term stability. Prepared showed pH‐dependent variation optical transmittance. Transmittance solution at pH 2.0 dramatically increased more than 200% transmittance 6. This change fully reversible. The detailed morphological features assemble evaluated dynamic light...
Abstract A highly electrically conducting and optically transparent silver nanowire (AgNW) network with enhanced oxidation resistance adhesion properties was formulated through poly(dimethylsiloxane) (PDMS) protection on top of the AgNW a poly(ethylene terephthalate) (PET) substrate. The PDMS-protected would prevent device malfunction in AgNW-based devices owing to its high by oxygen from air PET substrate, while minimizing any decrease optical transmittance increase sheet presence PDMS layer.
This study investigates patterns exhibited by pre-service teachers (PSTs) while practicing feedback in response to students' solutions on a procedure-based mathematics assessment. First, we developed an analytical framework for understanding PSTs' written feedback. Second, looked into how learning module multimedia platform influenced feedback, and identified the ways which PSTs subsequently revised their initial From this analysis, derived operational list of emergent content-specific Our...
In this article, the authors describe a 16-hour project-based learning statistics unit designed for and implemented with elementary-aged, African American children. The was to provide children mathematical experiences that allowed them make personal sense of mathematics or use critique analyze issues within their communities in wider society. worked thirteen, girls address an authentic, school-based problem; four dimensions equity—power, access, identity, achievement—was used as lens examine...
Stable aqueous dispersion of chemically reduced graphene oxide (RGO) was prepared through simple “catechol-induced reduction and functionalization” with a coffee catechol, chlorogenic acid (CA) or real Americano coffee. Prepared CA/RGO coffee/RGO assembly optically clear stable for more than 6 months. This catechol based approach the formulation soluble RGO can be easily extended to other “green chemistry” where catechol-rich fruits such as wine beverages berry juice used graphene.
A highly conductive silver (Ag) film or pattern was prepared on a poly(ethylene terephthalate) (PET) substrate by using room-temperature sinterable nanoparticle (AgNP) ink without any thermal treatment. The most critical factor in the sintering of AgNP molecular weight poly(N-vinylpyrrolidone) (PVP) ligand. AgNP-10 having PVP ligand with lowest 10000 Da produced Ag 6.3% conductivity bulk post-treatment such as heating.
The goal of the project this month is for students to design and build a tinfoil boat that capable carrying maximum weight with least expense, learning scientific concept buoyancy; incorporating technological tool TinkerPlots; applying engineering principles designing building boat; using mathematical knowledge area, graphs, data analysis. Integrating Science Technology Engineering in Mathematics (iSTEM) venue ideas activities stimulate student interest these integrated fields K–grade 6 classrooms.
