Therefore, the education department should also continue to carry out practice on the relevant talent training mode, to determine the talent training mode most suitable for the growth of polytechnic colleges. Colleges and universities should take entrepreneurship and innovation ability as the fundamental purpose so that students are not only job seekers, but also creators. The fuzzy set and its extended modelling are crucial for developing students' innovation skills. Therefore, on this basis, this paper proposed a model for cultivating innovative talents with fuzzy sets as the core. The fuzzy comprehensive evaluation (FCE) method is one of the most widely utilized and efficient evaluation methods, which applies to multi-objective evaluation models, thus reflecting the comprehensive and complex nature of the assessment. The ultimate purpose was to derive the decision rules and help the decision-makers make better decisions. The experimental findings of this article showed that there were 3 and 4 students with strong practical ability in Model 1 and Model 2 before the experiment, and there were 8 and 33 students with strong practical ability in Model 1 and Model 2 after the experiment.</p></div>","PeriodicalId":47305,"journal":{"name":"Learning and Motivation","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"92140695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With less durational experiences or extended education, programmers can have several ranges in theory-based universities. Teaching effectiveness in higher education strengthens students' impact and performance in the learning environment. The technological development in different platforms is completely understood and enhances education strategies. Community-based learning advantages for higher education are well recorded. The author concludes that educational institutions must make thoughtful choices about the parts they use, that they should strategically manage the network of internal and external stakeholders, including all communications and well-informed decisions, that they should recognize that shifts in student perceptions are common and encourage flexibility in system operations, and that it is normal for platforms to have specialized, high-performing departments/sections. The perspective of the group member is relatively less understood. Therefore, this paper proposes a community theory-based learning (CT-BL) framework to improve higher education learning technologies. CT-BL presents perspectives on how professors should contribute to strengthening partnerships between students and educators. The descriptive statistical model is used in a questionnaire session to recognize the central points in community participants' answers. Practical application of the framework within a variety of conservation groups illustrates the integrated approach's potential to serve as a portal through which practitioners can enter the realm of social science theory to better comprehend the current state and future directions of CT-BL interventions and activities. Students from several universities form collaborations to describe the way of theory-based learning. The community-based learning is evaluated based on the questionnaire raised by the learning participants. The community-based theory enhances higher education learning technologies. The overall participants of the University's higher education strategies are focused on community-based learning. Added teacher support for student awareness of information, experience, and competence and expanded academic participation in all cooperation elements involving advisor suggestions. The numerical results show that the proposed CT-BL model enhances the evaluation rate of 95.6%, reliability ratio of 94.2%, an efficiency ratio of 95.3%, the recognition accuracy of 90.3%, learning recognition rate of 92.2%, the impact of beliefs of 96.2%, dynamic nature rate of 93.4% when compared to other existing models.</p></div>","PeriodicalId":47305,"journal":{"name":"Learning and Motivation","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50177328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

JCL is an educational strategy that emphasizes collaboration, interdependence, and group cooperation. However, limited research has examined the specific impact of JCL on these factors among EFL learners. Thirty-eight learners from each of the two groups—one was the experimental group (EG) and the other was the control group (CG)—were randomly chosen from among the learners who had been chosen in the academic year 2023. Data were collected using three questionnaires on AM, AH, and SE. Before implementing the JCL treatment, both groups completed the questionnaires as a pretest. A post-test was administered after teaching JCL in the EG and using the traditional method in the CG. Descriptive and inferential statistics, including covariance tests, were conducted to analyze the collected data. The outcomes showed that JCL, as a cooperative learning technique, improved students' AM, AH, and SE. A comparison of the pretest and post-test results confirmed the significant and positive influence of JCL on AM, AH, and SE. These results suggest that the application of JCL techniques can facilitate the development of AM, AH, and SE among EFL learners. These findings have implications for EFL instructors and practitioners, as they can utilize JCL strategies to enhance their learners’ AM, AH, and SE in the classroom.</p></div>","PeriodicalId":47305,"journal":{"name":"Learning and Motivation","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50177329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intention is to argue whether there is a statistically significant difference in the acquisition and development of this competency between men and women of different ages during their training. Methodologically, a multivariate descriptive statistical analysis was carried out to demonstrate the relationship between these indicators. We concluded that there is evidence of a gender gap in developing the perceived achievement of the complex thinking competency and its sub-competencies since neither in the overall result nor in the specific results by indicator did women achieve results proportional to those of their male peers, although, in most competencies, they initially surpassed them.

We found that misconception revision occurred across both conditions, but at higher rates in the rephrase condition.

Thus, correctly generating one’s own information was critical for success in the self-derivation condition.
