Text Mining 101: What You Should Know

ABSTRACT

Scholars increasingly use text and data mining (TDM) methods to discover trends and relationships within complex digital data sets. In order to support this development in scholarly communication, librarians and publishers need to be knowledgeable about TDM methods, build partnerships with TDM researchers, and address challenges related to licensing and access to large document sets. The presenters of this NASIG session shared their experiences of supporting TDM as a library subject liaison, acquisitions librarian, and publisher representatives. Audience members discussed issues involving TDM of data from multiple publishers, local hosting of data sets and TDM activity by undergraduate students.     

Finding the diamond in the rough: Exploring communication and platform in crowdsourcing performance

Ideas that rise to the top in crowdsourcing platforms are assumed to succeed because they are perceived to be the best ideas, but questions about the factors that influence the outperformance of one solution over another remain underexplored. The Peer Vetted Ideas model is proposed as an explanation of elements that affect performance in crowdsourcing for creative ideation solutions. Using content analysis and hierarchical multiple regression, the study examined the relationship between performance in a public sector crowdsourcing competition and (a) design concepts, (b) communication about the designs, and (c) platform context. Results indicate that crowdsourcing is not always a meritocratic process to produce the objective “best” ideas, but rather also depends on subjective communicative, temporal, and platform factors.     

你接受挑战吗?

Should we easily wail about the embarrassment and the unfairness of life?Or should we accept obstacles as challenges?With a choice of stance we can allow ourselves to be oppressed victims.When anything happens to us,we can take it as a sign that we should not expect anything good out of our lives.These are times when we need to determine whether it is wisdom or fear that motivates us in our choices.……     

Assessment for Learning with Diverse Learners in a Digital World

We have the ability to capture data from students' interactions with digital environments as they engage in learning activity. This provides the potential for a reimagining of assessment to one in which assessment become part of our natural education activity and can be used to support learning. These new data allow us to more closely examine the processes learners use to solve problems, not just their final solutions, so educators can be more targeted in their intervention. New capabilities may address some of the consistent criticisms of assessment, but they also present new dangers, particularly for diverse learners. Systems are in danger of replicating the biases from our non-digital world in our digital tasks and in the creation of the scoring tools that accompany them.     

The mediating role of teacher self-efficacy in the relation between teacher–child race mismatch and conflict

The far-reaching impacts of the teacher–child relationship, including academic achievement and social/behavioral adjustment, have been well-documented. At the same time, literature also suggests that teacher perceptions of teacher–child relationships are impacted by the race/ethnicity match or mismatch between teacher and child, with matching related to more positive teacher perceptions. However, limited work has focused on children who are at-risk for emotional and behavioral disorders (EBDs) or tested the mechanisms that mediate the relation between a mismatch in the race and teacher-perceived conflict. Thus, the current study used multilevel structural equation modeling to test whether a higher proportion of race mismatch between children in the classroom with problem behavior and teachers was related to teachers' classroom management self-efficacy and, in turn, teacher-perceived conflict with children among 148 teachers and 354 preschool-aged children. Results indicated that among students most at-risk for EBDs, a higher proportion of race mismatch between teachers and children significantly predicted less teacher classroom management self-efficacy and, in turn, significantly predicted teachers' greater perceived conflict with children. Furthermore, this mediation pathway was significant. Findings highlight the importance of teacher training and support that focused on increasing self-efficacy to improve relationships between teachers and children.
