The article discusses the issue of shortage of skills in the Russian industry. Using microdata from a survey of industrial enterprises, the author confirms that most of employers complain of difficulties in hiring and attaching skilled workers. In case of mass occupations, this shortage relates mostly to low efficient enterprises, which are unable or unwilling to pay competitive market going wage. More efficient and better paying firms are less likely to face shortage of general skills on the labor market but may face limited supply of specific skills.

Early childhood teachers face competing instructional priorities to support specific academic skills and general skills that underlie learning, such as executive function (EF) skills that allow children to control their own thinking and behavior. As the evidence shows, EF skills predict later mathematics achievement, and early mathematics predicts later EF. These relations between mathematics and EF suggest high-quality mathematics teaching has a dual benefit: Teachers can promote children’s math and EF competencies by embedding support for EF in high-quality mathematics activities. Children benefit when guided to reflect on solutions and alternative strategies, and teachers benefit from guidance on how to support both math and EF. Finally, research on teachers developing both domains can inform educational policy.

AbstractThe purpose of this study was to generate consensus among experienced surgeons on “what skills a resident should possess before continuing safe training in the operating room (OR).” An online survey of 65 questions was developed and distributed to surgeons in the European community. A total of 216 responded. The survey included 15 questions regarding generic and specific skills; 16 on patient and tissue manipulation, 11 on knowledge of pathology and 6 on inspection of e-anatomical structures; 5 methods to prepare residents; and 12 on specific skills exercises. The importance of each question (arthroscopic skill) was evaluated ranging from 1 (not important at all) to 6 (very important). Chi-square test, respondent agreement, and a qualitative ranking method were determined to identify the top ranked skills (p < 0.05). The top four of general skills considered important were “anatomical knowledge,” “tissue manipulation,” “spatial perception,” and “triangulation” (all chi-square test > 134, p < 0.001, all excellent agreement > 0.85, and all “high priority” level). The top ranked 2 specific arthroscopic skills were “portal placement” and “triangulating the tip of the probe with a 30-degree scope” (chi-square test > 176, p < 0.001, excellent agreement, and assigned high priority). The online survey identified consensus on skills that are considered important for a trainee to possess before continuing training in the OR. Compared with the Canadian colleagues, the European arthroscopy community demonstrated similar ranking.

When learning a new concept, should students engage in problem solving followed by instruction (PS-I) or instruction followed by problem solving (I-PS)? Noting that there is a passionate debate about the design of initial learning, we report evidence from a meta-analysis of 53 studies with 166 comparisons that compared PS-I with I-PS design. Our results showed a significant, moderate effect in favor of PS-I (Hedge’s g 0.36 [95% confidence interval 0.20; 0.51]). The effects were even stronger (Hedge’s g ranging between 0.37 and 0.58) when PS-I was implemented with high fidelity to the principles of Productive Failure (PF), a subset variant of PS-I design. Students’ grade level, intervention time span, and its (quasi-)experimental nature contributed to the efficacy of PS-I over I-PS designs. Contrasting trends were, however, observed for younger age learners (second to fifth graders) and for the learning of domain-general skills, for which effect sizes favored I-PS. Overall, an estimation of true effect sizes after accounting for publication bias suggested a strong effect size favoring PS-I (Hedge’s g 0.87).
