First, one normally does not have any idea about. Two obstacles limit the modeling of these materials.
Such materials are often multicomponent with respect to number of distinct polymers, fillers, additives, etc. One general class of polymer modeling applications involves materials which are large, in terms of molecular degrees of freedom, and poorly defined in terms of composition and morphology. Subsequent details and feedback about the assignment are also presented.Keywords: First-Year Undergraduate/General Second-Year Undergraduate Organic Chemistry Communication/Writing Multimedia-Based Learning Student-Centered Learning In a more elaborate version of the assignment, students then proceed to make a YouTube video based on this written assignment. This work primarily focuses on a YouTube “video script” writing assignment where a student selects an organic chemistry concept and describes how they would “teach” or creatively explain the concept to their fellow classmates using real-world examples in a popular YouTube video format. Although writing assignments can be a method to incorporate peer- and self-explanation strategies, this method is not often incorporated in large lecture classes and lower-division science courses. This work describes efforts to incorporate and evaluate the use of a YouTube writing assignment in large lecture classes to personalize learning and improve conceptual understanding of chemistry through peer- and self-explanation strategies.

These files are available for download for further analysis. VLDPws provides output in two complementaryįorms: direct visualization of the Laguerre tessellation, mostly its polygonal molecular surfaces files of volumes and areas,Ĭontacts and similar data for each residue and each atom. At present, no equivalent web server is available. (iii) A measure of the residue exposure to solvent that significantly improves the standard notion (ii) A novel definition of inter-residue contacts High precision, as confirmed by good correlations with experimental data. Through this fine description, VLDPws gives the following data: (i) Amino acid volumes evaluated with The Voronoi Laguerre Delaunay Protein web server (VLDPws) computes the Laguerre tessellation on a whole given system firstĮmbedded in solvent. Propose a set of accurate tools, for analysing protein structures, based on the reliable method of Voronoi–Laguerre tessellations. Studying 3D protein structures is a key point for better understanding protein function at a molecular level. Protein structures are an ensemble of atoms determined experimentally mostly by X-ray crystallography or Nuclear Magnetic © 2013 by The International Union of Biochemistry and Molecular Biology, 2013. While a minority of instructors used a grading rubric/scoring matrix for assessment of student learning with molecular visualization, many expressed a desire for common use assessment tools. The most common uses of molecular visualization in teaching were lecture and lab illustrations, followed by exam questions, in-class or in-laboratory exercises, and student projects, which frequently included presentations.
The majority of respondents had used molecular visualization for more than 5 years and mentioned 32 different visualization tools used, with Jmol and PyMOL clearly standing out as the most frequently used programs at the present time.

Many common themes arose in the survey and the interviews: a shared passion for the use of molecular visualization in teaching, broad diversity in software preference, the lack of uniform standards for assessment, a desire for more quality resources, and the challenge of enabling students to incorporate visualization in their learning. To provide more depth to these results, interviews were conducted with 12 of the participants. Participants (n = 116) were asked to complete 11 multiple choice and 3 open ended questions. We have conducted a survey to begin a systematic evaluation of the current classroom usage of molecular visualization. It is a compelling medium that can be used to communicate structural information much more effectively with interactive animations than with static figures.
As biochemists, one of our most captivating teaching tools is the use of molecular visualization.
