[Objective] The aim was to analyze the phenomenon of employment diffi- culty and labor shortage, and to reveal the influencing factors of employment difli- culty and labor shortage. [Method] On the basis of the economic principle of popu- lation dividend, the use of human resources and natural resource constraints The IS-LM model describes these two states. [Results] The resource constraints have a "squeeze" effect on the demographic dividend, and employment pressure is shown in terms of the population opportunity window; the labor market segmentation, the ir- rational industrial structure, the backward curriculum and employment concept are the main factors affecting employment and labor shortage. [Conclusion] The way to solve this dilemma must be removed from the division of labor market, the adjust- ment of industrial structure, the setting of university specialty, the change of em- ployment concept of university graduates as well as the improvement of the quality of labor. 展开更多

The aim was to analyze the usefulness and importance of PBL, as a strategy of significant learning in daily experiences of nursing students during the COVID-19 pandemic. <strong>Method: </strong>The study was qualitative and phenomenological, with 15 informant students of the Module “Attention to addictions in the health area” aged 20 - 25 years, enrolled in the sixth semester of nursing from a public university. Data were collected through oral testimonies, texts, and semi-structured interviews of relevant aspects to them in their everyday life facing the COVID-19 pandemic, telling their experiences. Students signed an informed consent, and the qualitative analysis followed De Souza Minayo. <strong>Results: </strong>Four categories emerged: Category 1. Students’ experiences along pandemic;1.1, Positive experiences;1.2, Negative experiences. Category 2. Students’ knowledge and abilities for self-care along pandemic. Category 3. Abilities to promote problem solving. Category 4. Impact and usefulness of PBL in students’ experiences for health education;4.1, Positive impact of PBL;4.2 Negative impact of PBL. <strong>Conclusion:</strong> PBL is very useful for significant learning. It opens knowledge, developing skills to face, support, debate, evaluate and make decisions;it does incorporate critical thinking and problem solving. PBL does encourage collaborative work. 展开更多

Given that alcohol use is highly prevalent at US colleges, we explored factors related to problem drinking behaviors (PDB;binge drinking, driving after drinking, sexual intercourse after drinking) among 4098 Black and White students from two- and four-year colleges who completed an online survey. We found an interaction between race and sex such that, among Whites, females had less PDB than males (B = 0.09, CI: 0.05;0.40, p = 0.01). An interaction between race and school type also existed, such that White students from four-year schools had greater PDB (B = 0.11, CI: 0.20;0.54, p < 0.001). An interaction between race and stress suggested that Black students were more negatively affected by stress in terms of PBD (B = 0.12, CI: 0.01;0.07, p = 0.01). 展开更多

It is acquired by solving mathematical problems belonging either to routine or non-routine category. The study describes the post-secondary students’ levels of proficiency in solving non-routine math problems. The three-stage process in solving mathematics problems by Mayer was used as the frame of analysis. Using the data generated from researcher made instruments, and semi-structured interview of 50 purposively selected participants, the study found that: Majority of the participants showed “good proficiency” in “problem representation” and “problem solving”, the real world problems in Math. It is also revealed that those who are good in problem representation phase are also good in problem solution phase. In general, participants do not always consider answer verification phase as important in the process of solving real world problems in math. The most common difficulties encountered by participants are: language inadequacy and unfamiliarity with the context of the problems. The researchers recommended that the same study be done in some other context and local and if the results are consistent with this study, may consider redesigning new curriculum in post-secondary mathematics education. 展开更多

Objective: To explore the effects of self-directed learning readiness and learning attitude on problem-solving ability among Chinese undergraduate nursing students. Methods: A convenience sampling of 460 undergraduate nursing students was surveyed in Tianjin, China. Students who participated in the study completed a questionnaire that included social demographic questionnaire, Self-directed Learning Readiness Scale, Attitude to Learning Scale, and Social Problem-Solving Inventory. Pearson’s correlation analysis was performed to test the correlations among problem-solving ability, self-directed learning readiness, and learning attitude. Hierarchical linear regression analyses were performed to explore the mediating role of learning attitude. Results: The results showed that learning attitude (r=0.338, P<0.01) and self-directed learning readiness (r=0.493, P<0.01) were positively correlated with problem-solving ability. Learning attitude played a partial intermediary role between self-directed learning readiness and problem-solving ability (F=74.227, P<0.01). Conclusions: It is concluded that nursing educators should pay attention on students’ individual differences and take proper actions to inspire students’ self-directed learning readiness and learning attitude. 展开更多

The diagrams have been considered as one of the effective heuristic strategies or solving math problems. However, how students use during their school and the degree development that shows in their performance when applied to specific fields of knowledge is a task to be elucidated. We place our study in the school stage in which it makes the transition from arithmetic to algebra and arithmetic problems we focus on in the underlying multiplicative comparison scheme. In this paper, we analyzed the responses of high school students to the translation of multiplicative comparison word problems to representation graphs. We have used the responses of 12 -14 year old students (freshman year of secondary school) to represent multiplicative comparison word problems to identify and categorize the students responses, which allowed us identify categories for each type of representation and hypothesize priority order and subordination between the categories. Results show that students are not familiar with building diagrams that integrate existing relations in word problems. Most of the students do not use all the quantitative information contained in the word problem, therefore draw diagrams referring to the subject or context of the problem without relating to the data in it. We describe in detail the quantitative diagram types produced by these students. We have identified four kinds of quantitative diagrams that the students used to represent the multiplicative comparison problems with inconsistent statements, and these diagrams correspond to the four strategies for tackling the construction of the diagram. 展开更多

Introduction: The purposes of this study were to describe the simulation integrated with problem-based learning (SIM-PBL) module to educate the nursing process for clients with hypertension and to evaluate its effectiveness on nursing students’ self-efficacy (SE). Methods: This study was a one group pre- and post-test design. Twenty five students received a 5-hour SIM-PBL program focused on nursing care of clients with hypertension. A newly developed self-report questionnaire was used to assess SE in four areas of the nursing process with a scale of 0 (not at all confident) to 10 (totally confident). The four areas were subjective data assessment, physical examination, prioritizing nursing care and health promotion advices. Results: At baseline, students’ SE ranged from 5.5 ± 1.4 (prioritizing nursing care) to 7.6 ± 1.4 (subjective data assessment). After SIM-PBL education, all areas of nursing process presented statistically significant improvements of SE. The improvements were most noticeable in prioritizing nursing care. Conclusion: The SIM-PBL module was effective in improving the students’ self-efficacy in the nursing process for patients with hypertension. Further studies are recommended in developing SIM-PBL modules for diverse nursing topics and evaluating their effectiveness in various aspects of students’ competency. 展开更多

Background: Assessment of healthcare students’ mental health problems is an important aspect of health promotion. This study examined the roles of moral intelligence (MI) and identity styles in prediction of mental health problems in healthcare students. Methods: In a correlation study, two hundred healthcare students (100 girls, 100 boys) of Medicine, Density, and Paramedicine Colleges of Bobol University of Medical Sciences were selected. The subjects filled out three questionnaires;General Health Questionnaire (GHQ-28), Moral Competency Inventory (MCI), and Identity Style Inventory (ISI), and General Health Questionnaire (GHQ-28). Pearson correlation, multivariate analysis variance model (MANOVA), and multivariate regression used to analyze the data. Results: Boys and girls did not have a meaningful difference in the mean of total GHQ, MCI, normative and informational identity. Girls had significantly higher mean level of diffused-avoidant identity than boys. There was a positive and significant relationship between moral intelligence, normative identity and mental health problems of students. Also, there was a negative relationship (p < 0.05) between diffused-avoidant identity and mental health problems of students. Moral intelligence, informational and normative identity predicted 25.8% of the variance in mental health problems for girls’ students. Normative and diffused-avoidant identity predicted 21.6% of the variance in mental health problems for girls’ students. Conclusions: This study demonstrated that moral intelligence and identity status contributed to the mental health problems of healthcare students. University administrators should adopt strategies that strengthen the moral intelligence and identity maturity associated with university students’ mental health. 展开更多
