An Investigation of Creativity, Engagement, and Academic Success Using Student-Led Lesson Planning in One Third Grade Classroom

The purpose of this study was to investigate creativity, engagement, and student success using student-led lesson planning within a third-grade classroom. It was designed to see the impact of creativity on engagement and understanding through the use of daily student self-assessments and feedback, and daily input from students, concerning the upcoming lessons. The daily student self-assessments included three rating scales for engagement, creativity, and confidence in content. Each day, students were expected to rate themselves on a scale of one to five for each of the categories, regarding their views for that day’s lesson. This measured the effectiveness of each student-led lesson regarding the students’ reflections of their own engagement, feelings of creativity, and the degree of understanding. In addition to the daily ratings, students also gave input for the next lesson, based on their ratings for the current lesson. This allowed students to be creative in using their problem-solving skills to suggest a more effective lesson style. There were twenty-four students who participated in the week-long study. At the conclusion of the study, the results of the daily surveys were analyzed for every question using a paired-samples t-test with an alpha level set at .05. The t-test revealed a significant increase in ratings in all three categories of engagement, creativity, and confidence in understanding between the beginning and end of the study. Therefore, student-led lesson planning was found to positively impact the engagement, creativity, and student success of one group of third-grade students

4-[Bis(4-fluoro­phen­yl)meth­yl]piperazin-1-ium 2-hy­droxy­benzoate 2-hy­droxy­benzoic acid monosolvate

The title compound, C17H19F2N2 +·C7H5O3 −·C7H6O3, is a co-crystal from 4-[bis­(4-fluoro­phen­yl)meth­yl]piperazin-1-ium, salicylate anion and salicylic acid in a 1:1:1 ratio. In addition to an intra­molecular O—H⋯O hydrogen bond, the crystal packing shows hydrogen bonds between the piperazinium cation and salicylate anion (N—H⋯O), as well as between the salicylic acid mol­ecule and anion (O—H⋯O), giving rise to a three-dimensional network

4-[Bis(4-fluorophenyl)methyl]piperazin-1-ium picrate

The title compound {systematic name: 4-[bis(4-fluorophenyl)methyl]piperazin-1-ium 2,4,6-tri­nitro­phenolate}, C17H19F2N2 +·C6H2N3O7 −, is the picrate salt of a piperazine-supported amine bearing a benzhydryl substituent on one of its N atoms. During co-crystallisation, protonation took place on the N atom of the secondary amine functionality. The non-aromatic six-membered heterocycle adopts a chair conformation. In the crystal, N—H⋯O hydrogen bonds as well as C—H⋯O contacts connect the components into a three-dimensional network

Comparative 3D QSAR study on β1-, β2-, and β3-adrenoceptor agonists

A quantitative structure–activity relationship study of tryptamine-based derivatives of β1-, β2-, and β3-adrenoceptor agonists was conducted using comparative molecular field analysis (CoMFA). Correlation coefficients (cross-validated r2) of 0.578, 0.595, and 0.558 were obtained for the three subtypes, respectively, in three different CoMFA models. All three CoMFA models have different steric and electrostatic contributions, implying different requirements inside the binding cavity. The CoMFA coefficient contour plots of the three models and comparisons among these plots provide clues regarding the main chemical features responsible for the biological activity variations and also result in predictions which correlate very well with the observed biological activity. Based on the analysis, a summary regeospecific description of the requirements for improving β-adrenoceptor subtype selectivity is given

Micellar Promoted Multi-Component Synthesis of 1,2,3-Triazoles in Water at Room Temperature

Micellar media in water provide a simple and efficient environment to favor the multi-component synthesis of 1,2,3-triazoles from organic bromides, sodium azide and terminal alkynes in the presence of [Cu(IMes)Cl] 1 catalyst at room temperature within few hours. The micellar medium favors both the in situ formation of the organic azide and its metal promoted cycloaddition with the alkyneMicellar media in water provide a simple and efficient environment favoring the multi-component synthesis of 1,2,3-triazoles from organic bromides, sodium azide and terminal alkynes in the presence of [Cu(IMes)Cl] 1 catalyst at room temperature within a few hours.
