Always show students the outcome or product before they do it.Try a fishbowl activity, where a small group in the center is circled by the rest of the class the group in the middle, or fishbowl, engages in an activity, modeling how it’s done for the larger group.
#On the scaffold meaning how to#
Have you ever interrupted someone with “Just show me!” while they were in the middle of explaining how to do something? Every chance you have, show or demonstrate to students exactly what they are expected to do. How many of us say that we learn best by seeing something rather than hearing about it? Modeling for students is a cornerstone of scaffolding, in my experience. Or perhaps you’ve not used them in some time and need a gentle reminder on how awesome and helpful they can be when it comes to student learning. So let’s get to some scaffolding strategies you may or may not have tried yet. Education researcher Eileen Raymond says, “The ZPD is the distance between what children can do by themselves and the next learning that they can be helped to achieve with competent assistance.” In order to meet students where they are and appropriately scaffold a lesson or differentiate instruction, you have to know the individual and collective zone of proximal development (ZPD) of your learners. Scaffolding and differentiation do have something in common, though. For those students who are still struggling, you may need to differentiate by modifying an assignment or making accommodations like choosing a more accessible text or assigning an alternative project. Simply put, scaffolding is what you do first with kids. With differentiation, you might give a child an entirely different piece of text to read, or shorten the text or alter it, or modify the writing assignment that follows. When scaffolding reading, for example, you might preview the text and discuss key vocabulary, or chunk the text and then read and discuss as you go. Scaffolding is breaking up the learning into chunks and providing a tool, or structure, with each chunk. Let’s start by agreeing that scaffolding a lesson and differentiating instruction are two different things.
#On the scaffold meaning series#
In FASTA sequences, gaps are represented by a series of Ns.What’s the opposite of scaffolding a lesson? Saying to students, “Read this nine-page science article, write a detailed essay on the topic it explores, and turn it in by Wednesday.” Yikes! No safety net, no parachute-they’re just left to their own devices. Gaps are shown in the Genome Viewer as red lines or rectangles in the scaffold track (viewed in "full" mode). Thus, a sequence that exists in only one location in the genome may appear on more than one scaffold. For example, in polymorphic genomes, regions with a high density of allelic differences between haplotypes may be split into separate sets of scaffolds, each representing one allele. Some scaffolds may ultimately be filtered out of the assembly, resulting in skipped scaffold numbers. Scaffolds are normally numbered approximately from largest to smallest. Relative locations of scaffolds in the genome are unknown. Or just a single scaffold (e.g., Human chromosome 19), depending on howĬompletely the genome can be reconstructed, or assembled, from the available May be represented by many scaffolds (e.g., Chlamydomonas Sequence in one scaffold however, this is not always possible. The goal of whole-genome shotgun assembly is to represent each genomic Since the lengths of the fragments are roughly known, the number of bases between contigs can be estimated. Gaps occur where reads from the two sequenced ends of at least one fragment overlap with other reads in two different contigs (as long as the arrangement is otherwise consistent with the contigs being adjacent). A contig is a contiguous length of genomic sequence in which the order of bases is known to a high confidence level. Scaffolds are composed of contigs and gaps. > What is a Scaffold? What is a Scaffold?Ī scaffold is a portion of the genome sequence reconstructed from end-sequenced whole-genome shotgun clones.
