by discovery layer, the moderators were referring to the variety of tools available to libraries that bring together article-level content, specialized databases, and the content traditionally found inside a library catalog (e.g., books and journal titles) into a single searchable index. Based on the survey, 67% of e-forum participants are using a discovery layer and 83% maintain this layer alongside the traditional catalog. During the e-forum participants identified a number of commercial systems in use at their libraries (Summon, Encore, EDS, WorldCat Discovery, Primo), as well as some customized or open-source products. Participants at some specialized and public libraries expressed opinions that discovery layers do not fit their institutional needs, either because of the lack of sophisticated searching or specialized content, or because of overemphasis on article content.
In academic libraries, discovery layers tend to be the preferred tool for undergraduates, while more advanced scholars (and some library staff) prefer the traditional library catalog for known items, additional search features, and more specialized content. Discussion about the different levels of user sophistication and varying research needs continued through the entire e-forum. One participant put the difference between searching in terms of recall versus precision. Discovery makes an ideal tool for quickly returning at least some relevant results—great for basic research—but often brings back a large number of irrelevant results in a huge set.
From a technical services perspective, discovery layers have led to changes in technical services operations.
Discovery systems are not one size fits all. Special collections librarians and consortial members shared some concerns about the way discovery systems display information.
Good Question! What is a Discovery Layer?
By Gwen Evans Executive Director, OhioLINK Thursday, January 16, 2014 – 9:50am
a discovery layer is a Google-like search across all library resources. In library language, a discovery layer is a searchable meta-index of library resources, usually including article-level metadata, e-book metadata, metadata from library catalogs, open access resource metadata, etc., and it includes a means of retrieving resources in the result set through linking technology.
Why is a discovery layer needed for libraries?
Without a discovery layer, users have to search many separate silos of information one by one – the library catalog for books and journals, publisher sites and individual ejournals in particular subjects for articles, and other specialized databases. Even for experienced users who know which databases and resources are likely to be most relevant to their needs, this is time-consuming and involves duplicating the same search over and over in different places. For novice users, or those who want a broad, interdisciplinary search, the initial choice of resource can be daunting and frustrating, unless users already know to ask their librarians for help. In addition, every database or resource interface is different – there are many similarities, but users have to learn different procedures and strategies for each information silo. While specialized interfaces deliver a lot of power for the advanced user, sometimes they can get in the way for other kinds of tasks.
Why not just use Google or another search engine?
Many library resources are difficult to find using search engines, even if a user is savvy enough to be using Google Scholar or Microsoft Academic Search instead of regular Google or Bing. In addition, almost all online library resources, such as full-text articles and ebooks, are most decidedly not free or open access – academic libraries pay quite a bit of money for them
Who should deliver PD, the administrators or the teachers?
very important is for blended learning to not be a separate, compartmentalized aspect of learning at a school site.
With traditional PD, we’re bringing people in constantly and we’re taking them out of their classrooms. But I think one of the effective strategies for teachers is to actually bring them into classrooms, to see [blended learning] in action. It’s one thing to sit at a table and be given pedagogical practices and do the variety of things we normally do at a traditional PD.
In blended learning, we can move a lot of that more pedantic stuff to an online environment, and then the actual PD becomes collaborative.
one of the things that we might want to consider is the “fear factor” involved…. It’s overcoming fear and not overwhelming teachers, and that’s why delivering PD in a blended environment gives them that time to absorb, I think. I think that’s absolutely critical.
we recorded everything, had a webinar and put it on YouTube, so it was accessible for them afterwards.
I’d say along similar lines—stop introducing products or resources or tools out of context. So, if you say there’s a great new tool you may consider using and you just show the tool but there’s no context for it, I think it’s going to be difficult to get teachers to buy-in because it just seems like one more thing.
Constructivism.
Student-centered learning theory and practice are based on the constructivist learning theory that emphasizes the learner’s critical role in constructing meaning from new information and prior experience.
The “context”in this definition encompasses m-learnng that is formalself-directed, and spontaneous learning, as well as learning that is context aware and context neutral.
therefore, m-learning can occur inside or outside the classroom, participating in a formal lesson on a mobile device; it can be self-directed, as a person determines his or her own approach to satisfy a learning goal; or spontaneous learning, as a person can use the devices to look up something that has just prompted an interest (Crompton, 2013, p. 83). (Gaming article Tallinn)Constructivist Learnings in the 1980s – Following Piage’s (1929), Brunner’s (1996) and Jonassen’s (1999) educational philosophies, constructivists proffer that knowledge acquisition develops through interactions with the environment.

96-97). Keegan (2002) believed that e-learning was distance learning, which has been converted to e-learning through the use of technologies such as the WWW. Which electronic media and tools constituted e-learning: e.g., did it matter if the learning took place through a networked technology, or was it simply learning with an electronic device?

How One District Created a Culture of Innovation Through Interoperability
Join the Executive Director of Technology for the School District of Pickens County in South Carolina, Barbara Nesbitt, on Thursday, February 22 at 1pm EST to hear how they used Schoology to:
Centralize their technologies and resources
Save teachers time to focus on student achievement
Ensure a consistent student experience from grade-to-grade
1. Technology that Increases Access Hits the Slow Lane
Innovations in videoconferencing and lecture capture technologies have allowed universities to provide flexible learning experiences to students no matter their location. However, if internet service providers are allowed to create “fast lanes” and “slow lanes” of access, experts worry these learning experiences will be in jeopardy. “slow lanes” of internet access could make it difficult for students to access cloud software or applications without hitting data caps.
2. Inhibit Ability to Research and Access Materials
a 40-page commentary to the FCC explaining how a repeal would hurt universities, eCampus News reports.
“Institutions of higher education and libraries depend upon an open internet to carry out their educational and civic missions, and to serve their communities,” reads the commentary.
“almost everything” relies on the internet in higher education. Students use it for research, to take courses and turn in assignments while faculty use it for research and to create lesson plans. Roberts says his library needs it to archive and preserve materials. Slower internet could inhibit research and access to library resources.
3. Increased Costs Without Increased Educational Experiences
high cost of attending a university might see a bump without net neutrality. slower internet access would actually degrade the quality of education offered for a higher cost.
A new report from the Learning House and Aslanian Market Research measures the opinions of 1,500 online students regarding everything from course satisfaction to study methods
institutions need to more clearly share the positive outcomes that come with completing degree and certificate programs online.”
online courses would be better if there was more contact and engagement.
What is digital literacy? Do you know how you can foster digital literacy through formal and informal learning opportunities for your library staff and users?
Supporting digital literacy still remains an important part of library staff members’ work, but sometimes we struggle to agree on a simple, meaningful definition of the term. In this four-week eCourse, training/learning specialist Paul Signorelli begins by exploring a variety of definitions, focusing on work by a few leading proponents of the need to foster digital literacy among people of all ages and backgrounds. He explores a variety of digital-literacy resources – including case studies of how we creatively approach digital-literacy learning opportunities for library staff and users, and explores a variety of digital tools that will help to encourage further understanding of this topic.
