Mental Effort and Performance as Determinants for the Dynamic Selection of Learning Tasks in Air Traffic Control Training

The differential effects of four task selectionmethods on training efficiency and transfer incomputer-based training for Air Traffic Controlwere investigated. A non-dynamic condition, inwhich the learning tasks were presented to theparticipants in a fixed, predeterminedsequence, was compared to three dynamicconditions, in which learning tasks wereselected on the basis of performance, mentaleffort, and a combination of both (i.e., mentalefficiency). Using the 3-factor mentalefficiency formula of Tuovinen and Paas (2004, this issue), the hypothesis that dynamic taskselection leads to more efficient training thannon-dynamic task selection was confirmed.However, the hypothesis that dynamic taskselection based on mental efficiency leads tomore efficient training than dynamic taskselection based on performance or mental effortalone was not supported. The results arediscussed in light of the theoretical frameworkand suggestions are given for futureresearch.     

The Role of Instruction for Spelling Performance and Spelling Consciousness

This study examined the role of instruction for spelling performance and spelling consciousness in the Dutch language. Spelling consciousness is the ability to reflect on one's spelling and correct errors. A sample of 115 third-grade spellers was assigned to a strategy-instruction, strategic-monitoring, self-monitoring, or control condition representing different types of metacognitive aspects. The results showed that students in all three training conditions made more progress in both spelling performance and spelling consciousness than students in the control condition. With respect to spelling consciousness, only students in the strategy-instruction condition made significant improvement between pretest and posttest. Students made more progress in spelling performance on regular words than on loan words. Students in all four conditions became more accurate at assessing which words they could spell correctly. Students in the control condition more frequently overestimated their spelling ability.     

Piloting a long-term evaluation of library data workshops

Background:Over four years of hosting library data workshops, we conducted post-workshop evaluation of attendees'' satisfaction with the workshops but not longer-term follow-up. To best allocate library resources and most effectively serve the needs of our users, we sought to determine whether our data workshops were impactful and useful to our community. This paper describes a pilot project to evaluate the impact of data workshops at our academic health sciences library.Case Presentation:We surveyed individuals who signed up for data workshops between 2016 and 2019. Surveys included open-ended and multiple-choice questions, with the goal of having participants describe their motivations for taking the workshop(s) and how they ultimately used what they learned. An analysis of responses using the Applied Thematic Analysis model indicated that the workshops had an impact on the respondents, although the strength of our conclusions is limited by a relatively low response rate.Conclusions:Survey results indicated that our workshops impacted how researchers at our medical center collect and analyze data, supporting the conclusion that we should concentrate our educational efforts on providing skills-based workshops. The low response rate and time-consuming nature of the analysis point toward several improvements for future evaluation efforts, including better tracking of workshop attendees, a shorter survey with fewer open-ended questions, and survey implementation within one year of the workshop date.     

Historical Evolution of the Field View and Textbook Accounts

We analyzed how two basic electromagnetism textooks approach the concept of electric field. We limited our study to the reasons given in these textbooks for the introduction of the field representation and to how accurate, coherent, and complete these reasons are. Because many times historical reasons are intertwined with textbooks' explanations of physical phenomena, we used the historical evolution of the field representation to guide our analysis. The analysis shows that one textbook mixes up the historical and pedagogical reasons for the introduction of the concept of field. The other one presents a sketch that might lead students to understand the field and the action-at-a-distance views as supplementing each other.     

The Refined and Further Defined Freedom Paradigm: A Response to Ottens and MacCluskie

The proposed freedom paradigm is briefly reviewed as an overarching framework that may provide a structure for integrating the counseling profession and counseling theories. Freedom is defined and discussed in terms of four modalities: freedom from, freedom to, freedom with, and freedom for. This is followed by a response to comments on Hanna's (2011) article and addresses such topics as the nature of practice, the value of techniques, hypnotherapy, and the applicability of the paradigm for mental health professionals in general. A further clarification of counseling toward object orientation and internal control is also included.     

An Essay: Reflecting on Your Laurels

We all know we are not supposed to rest on our laurels but there is great benefit to be had from reflecting on them. This essay lays out a tool known as The Goals Grid. It can be used to examine how you got to where you are and to set directions for where you want to go from here. Its four quadrants—Achieve, Preserve, Avoid, and Eliminate—will accommodate all goals and objectives.
