This paper presents an explorative holistic analysis of digitally-constructed gamification processes in mathematics education. The main aim of this study is to identify the key issues, intentions and trends by examining peer-reviewed publications using a combination of social network analysis (SNA), computerized lexical analysis and content analysis. Research findings indicate that there is a growing trend in gamification in mathematics education (GIME) research. GIME is mostly employed in primary school level. It was also found that, numbers is the most gamified math topic. Another research finding reveals that the researchers mostly use gamification to improve mathematical problem-solving, math achievement and math performance apart from the motivation and engagement. According to SNA findings, the most strategic terms in GIME research are as follows; geometry, fractions, mobile-learning, gender-studies, human-computer interaction, intelligent tutoring systems and tangible user-interfaces. GIME research is mostly influenced by USA and Brazil hence, the developing countries have an increasing interest in GIME research. Finally, findings on general research discourse implies that the general discourse among the sampled papers is positive. The findings obtained in this study may be useful to improve mathematics education by mapping a research agenda for researchers and educators with the exploration of potentials of GIME research.

A documentary review was conducted on the production and publication of research papers on studying the variable Digital Transformation, Education and COVID-19. The bibliometric analysis proposed in this document aims to know the main characteristics of the volume of publications registered in the Scopus database from 2020 to 2022, achieving the identification of 464 publications in total. The information provided by this platform was organized using tables and figures, categorizing the information by Year of Publication, Country of Origin, Area of Knowledge and Type of Publication. Once these characteristics were described, the position of different authors regarding the proposed topic was referenced through qualitative analysis. Among the main findings of this research, it is found that Spain, with 49 publications, was the country with the highest global production. The area of knowledge that made the most significant contribution to the construction of bibliographic material related to the study of Digital Transformation, Education and COVID-19 was the area of Social Sciences with 253 published documents, and the type of publication that was most used during the period mentioned above was the journal article, representing 54% of the total scientific production.

The study discussed in this paper is a systematic literature review related to the role of dual language programme (DLP) in mathematics education which has been published within the last 5 years. This study was conducted to identify the distribution of DLP studies in terms of year of publication, the study context covered in previous studies, the context of study areas used, focus and trends of past studies, research methods used in previous studies and the role of language in school mathematics education. This review study followed the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) to analyze articles from Scopus and Web of Science. The findings of the study indicate that research trends in the implementation of the DLP on mathematics education for secondary school students showed an increase from 2017 to 2019. Most DLP-related articles are widely developed in the United States and Germany. The findings indicate that previous studies are more interested in studying the implementation of DLP in rural areas. Past studies have also preferred to use the design of either a qualitative study or a quantitative study to be implemented. Questionnaires, tests and interviews are among the research instruments that are often used for a study.

This paper revisits the relationship between human capital and income inequality, using an updated data set on human capital inequality and a novel database on earnings inequality. We find an inverted U-shaped relationship between these two inequality indicators, but with significant differences across countries regarding the turning point. Skill-biased technological change is found to be an additional force that may blur the relationship between human capital and earnings inequality. Over and above the effect exerted through earnings inequality, the paper shows that human capital inequality has a direct positive effect on income inequality.

Numerous studies in different science fields have examined the various aspects of educational interventions designed to facilitate learning outcomes in students with dyslexia. The aim of this study was to present an overview of empirical research related to interventions aimed at primary school students with dyslexia. Mapping was conducted to identify studies on this topic published from 2015 to 2019 and included in the Scopus database. The descriptive data from 57 studies were analyzed to present a classification scheme of research design, type of educational intervention, implementation of technology in educational interventions, and aim of the intervention. The results indicated an increasing trend in the last 5 years in the publication of papers in researched areas related to educational interventions for students with dyslexia, with uneven representation among countries. The analyzed empirical studies were mostly analytic, using different designs, with a slightly higher prevalence of (quasi) experimental versus descriptive designs. As expected, the goal of most educational interventions was directed toward the development of (pre)reading skills, with a wider prevalence of structured language-based programs, followed by software specialized to support learning, whereas adaptations of instructional materials and innovative information and communication technology (ICT) were less used. Mapping indicated the frequent use of ICT in all educational interventions, and more evidence is needed for complex rigorous experimental designs and interventions related to teaching in the classroom, as well as interventions aimed at facilitating the self-regulation of students with dyslexia.

Purpose: The Farmer Field School (FFS) has been used to enable farmers to adapt their farming decisions according to the field situation. This paper explores the methodological state, challenges and lessons learned, of the FFS around the World. Design/methodology/approach: We used a 52-item questionnaire to capture issues of design, implementation and evaluation of the FFS. Completed questionnaires were received from 57 ongoing or recent FFS programmes. Data were analysed using descriptive statistics. Findings: FFS programmes have diversified, including multiple crops and livestock. Farmer involvement in the design and planning of interventions was found to be critical. FFS programmes increasingly relied on farmers as FFS facilitators. Short training duration for FFS facilitators raised concern about FFS quality. Even though mechanisms for monitoring and evaluation were mostly in place, capacity for data analysis and data utilization were a concern. Practical implications: Results highlight strengths and shortcomings in design, implementation and evaluation of the FFS. The information acquired can be used to support the quality of ongoing and future programmes. Theoretical implications: This research contributed to understanding that the educational foundations of the FFS should be reflected in programme design and evaluation. Originality/value: Many studies of the FFS exist, but this is the first global overview on how farmer field school programmes are carried out, with various lessons learned.
