This paper presents and analyzes results of two Delphi processes that polled cybersecurity experts to rate cybersecurity topics based on importance, difficulty, and timelessness. These ratings can be used to identify core concepts--cross-cutting ideas that connect knowledge in the discipline. The first Delphi process identified core concepts that…

This article reports the analysis of six urban contexts in which a practical tool measuring individual skills concerning household waste recycling was tested. The tool is a structured questionnaire including a simulation task that assesses respondents' abilities to sort household waste adequately in a given context/municipality. Results indicate…

Practical training and actual application of acquired knowledge and techniques are crucial for the learning of technical skills. We established a wireless sensor network system (WSNS) based on the 5E learning cycle in a practical learning environment to improve students' reflective abilities and to reduce difficulties for the learning of technical…

Research has shown that spatial thinking is important in science in general, and in Earth Science in particular, and that performance on spatially demanding tasks can be fostered through instruction. Because spatial thinking is rarely taught explicitly in the U.S. education system, improving spatial thinking may be "low-hanging fruit" as…

Computer-based assessment can provide new insights into behavioral processes of task completion that cannot be uncovered by paper-based instruments. Time presents a major characteristic of the task completion process. Psychologically, time on task has 2 different interpretations, suggesting opposing associations with task outcome: Spending more…

The purpose of the present study is to determine the extent to which pre-service Turkish Language and Literature teachers possess summarizing skill. Answers to the following questions were sought in the study: What is the summarizing skill level of the pre-service Turkish Language and Literature teachers? Which of the summarizing rules are…

In manual assembly work, parts are often assembled by applying force with a simple tool or by hand. A worker thus needs control the force he or she applies in working, as an appropriate level of force is requisite for minimizing work failures and improving efficiency. The object of this study is to clarify the relationship between the level of…

The relative difficulty of seven test wiseness skills was studied with 243 undergraduates, who completed a measure of such skills. The use of specific determiners as a cue was significantly more challenging than eliminating irrelevant alternatives, selecting the alternative with the most information, or using grammar cues.

Research on the effects of numerical control (NC) machining on the skills of machinists presents mixed results. Interviews with a small group of machinists experienced in both conventional and NC matching suggest seven major factors that affect whether NC automation changes the overall skill level. The deskilling hypothesis is not supported by…

The study examined the possible existence of a perceptual hierarchy which is systematically affected by the onset of adventitious visual impairment. Results with 80 persons with partial vision indicated a demarcation of difficulty between the simpler and more complex levels of the hierarchy. (DB)

Three experiments were undertaken to examine the processing limitations that underlie multiple task performance and, ultimately, to test the theory that there exists a time-sharing ability which is general and can be assessed through the simultaneous presentation of any two or more sufficiently demanding tasks. Subjects were males and/or females…

Developmental differences in summaries of expository texts were examined for fourth and sixth grade students in two experiments. Experiment 1 used texts that had a description content structure whereas Experiment 2 texts had a thesis/evidence content structure. Manipulation of the presence or absence of the topic sentence allowed the examination…

White and Gagne's method (EJ 180 555) for formatively evaluating learning hierarchies does not require participants to be taught the content prior to testing them for their knowledge of the skills in the hierarchy. By simply determining the percentage of students achieving each skill, the researcher obtains approximately the same information.…

Researchers examined the effect of writing in response to simple and complex pictures on students' narrative writing. Findings indicated that fourth graders use different composing behavior and produce different written products than do sixth graders, writing more coherently/cohesively for complex than for simple tasks.

This study added extraneous information and increased syntactical complexity to determine the relative importance of computational and reading abilities in solving arithmetic word problems. Analyzing tests of 200 sixth graders indicated the combined abilities accounted for 54 percent of the variance in solution accuracy. (BS)
