Gender differences in kindergarteners’ robotics and programming achievement

Early childhood is a critical period for introducing girls to traditionally masculine fields of science and technology before more extreme gender stereotypes surface in later years. This study looks at the TangibleK Robotics Program in order to determine whether kindergarten boys and girls were equally successful in a series of building and programming tasks. The TangibleK Program consisted of a six lesson robotics and programming curriculum that was implemented in three different kindergarten classrooms (N = 53 students). Although previous research has found that males outperform females in robotics and programming related fields, it was hypothesized that the young age of participants and their limited cultural indoctrination regarding gender stereotypes would allow boys and girls to have equal success in this program. Although boys had a higher mean score than girls on more than half of the tasks, very few of these differences were statistically significant. Boys scored significantly higher than girls only in two areas: properly attaching robotic materials, and programming using Ifs. Overall, both boys and girls were able to successfully complete the program.     

Bridging the gender gap in science and technology: How long will it take?

Conclusions Throughout the year the girls maintained the progress made in the first school and continued to develop their ability to implement physical science concepts in their modelling work. They reached a point sometime during year 4 when collectively they achieved parity with the boys in this respect. By the end of the year there were more concepts put into practice with greater frequency by girls than by boys as groups. Although it took a long time to reach this point it was achieved through practices compatible with normal teaching using materials easily available in school.Analysis of the models under the two criteria of variety and creativity showed that despite the greater frequency which girls incorporated physical concepts into the models made there was still a tendency for them to be conservative. They chose to make models which were the same as those illustrated on the work cards or those produced by other girls. Despite the fact that they made more models than the boys the range of models made by girls was smaller. Girls were also less likely to be creative They did not often modify their models by adding elements of their own design and rarely developed designs of their own in contrast to the boys which were often original and innovative.     

Gender differences in social cognitive learning at a technological project design

This study aims to investigate the differences between male and female students in technology project design. The major gender differences discussed in this study include the problem discovering and solving abilities, maneuverability, and inquiry attitude among middle grade students. In the project design, students were required to design and complete a wooden robot with limited materials in a restricted timeframe. Data was collected through field study during the project making. The results of this study indicated that some differences existed between male and female students. For example, power tool manupulation was more appealing to boys than girls. On the other hand, girls were better at resource management than boys. Through social learning, female students have an overtime improvement. Pedagogical considerations are suggested to strengthen gender-specific problem solving skills, so that all students can realize their design potential.     

The things that belong: a grounded theory study of student categorizations of complex technical artifacts

Technical artifacts play a central role in teaching and learning about technology. The artifact exemplars used in the classroom to illustrate and discuss various technological concepts should therefore be carefully chosen in order to actually support the abstraction and successful transfer of these concepts. Research from the learning and cognitive sciences strongly suggests that this requires an understanding of how students actually perceive and conceptualize various technical artifacts, what similarities, differences and features are most salient and meaningful in their eyes. In this paper, we propose a grounded theory of how students differentiate and relate various complex technical artifacts. The core of our theory is formed by four hierarchically ordered juxtapositions: (1) technology versus non-technology, (2) everyday versus specialized, (3) private versus public, and (4) luxury versus necessity, which divide the realm of technical artifacts into five broad categories: high technology, household technology, public technology, real technology, and no/low technology. Our claim is that these differentiations and categories are generally salient and meaningful for students. Based on the theory of variation, we outline how they might help educators make more informed and systematic selections of exemplar artifacts to use in the classroom.     

Evaluating the impact of individual fishing quotas (IFQs) on the technical efficiency and composition of the US Gulf of Mexico red snapper commercial fishing fleet

This study examines the impact of individual fishing quotas (IFQs) on the technical efficiency (TE) and composition of the Gulf of Mexico red snapper commercial fishing fleet. Employing a parametric stochastic distance frontier framework we find that IFQs improved the TE of the vertical line and bottom longline fleets. Our results suggest that the observed TE gains were mainly driven by the retirement of less efficient vessels and, to a lesser extent, by efficiency gains of the remaining vessels. We also document changes in output and input distance elasticities and in returns to scale following the introduction of IFQs. The paper also investigates the impact of regulations and weather on productivity and the effect of crowding on TE. Policy implications stemming from these results are also discussed.     

Gender and Technology in Hong Kong: A Study of Pupils' Attitudes Toward Technology

Attitudes play an important role in guiding and predicting future actions. In Hong Kong, where traditional attitudes regarding female and male roles often clash with more-modern influences, students' negative or positive attitudes toward technology have obvious implications for their participatory role in society. This paper reports on a study of Hong Kong Pupils' Attitudes Toward Technology. Items in a survey distributed to nearly 3,500 junior secondary school students were used to gauge their attitudes toward several areas of technology. Questions related to parents' careers and domestic influences were also asked.The analysis revealed that significant differences existed between girls and boys in many of the items. For instance, the importance of taking technical subjects such as Design & Technology (D&T) was found to be significant in their attitudes about technology being an activity for both genders. Similarly, students' interest in technology, attitudes about technology in the school curriculum, and ideas about careers related to technology showed significant differences between girls and boys. Given the results of the study, changes in Hong Kong's secondary school D&T are proposed. Current strategies being developed in Hong Kong's D&T teacher preparation programs are also outlined.     

Promoting Girls' Interest in Technology through Technology Education: A Research Study

The article summarises the design and outcome of an inquiry into the promotion of interest in technology by technology education. The reason for the present study is the low proportion of women in technical occupations, studies or subjects. Such a marked gender difference leads to different ways of life which discriminate against women. It is necessary, therefore, to search for the underlying causes and to take measures in order to support technological activities. The aim of the German study was to determine differences in the interests of girls and boys in technology and to support interest more widely in technology by technology education. The study was conducted in a class in the third year of elementary education. At first, differences between girls and boys in the intensity and gearing of interest in technology were determined by a survey. After exposure of a `treatment Group' to technology education, the effects of such education were established by mean of a second survey. The results of the first and second survey were compared. The results show that the interests of girls and boys were aroused by technology education. Furthermore, gender differences are reduced significantly. The findings of this study suggest that it is essential to intensify technology education in elementary school because it is the earliest opportunity for curriculum intervention.

Horticultural exports,female wage employment and primary school enrolment: Theory and evidence from Senegal

In this paper we analyse the indirect effects of the boom in horticultural exports in Senegal on child schooling. The export boom has caused a dramatic increase in female off-farm wage employment, which led to increased female bargaining power in the household. We investigate the causal effect of female wage income on primary school enrolment. We develop a collective household model with endogenous bargaining power to show that, if women have higher preferences for schooling than men, the impact of female wage income on school enrolment will be the result of a positive income effect, a negative labour substitution effect and a positive empowerment effect. We address the question empirically using original household survey data from Senegal. We use different econometric techniques and show that female off-farm wage income has a positive effect on primary school enrolment for both boys and girls, and that female empowerment is specifically important for the schooling of girls. Our results imply that the horticultural export boom in Senegal has indirectly contributed to the second and third Millennium Development Goals of universal primary education and elimination of gender disparities in primary education.     

How study aids influence learning and motivation for girls in technology education

Sciences and technology study and technological jobs are deserted by girls. Many measurements were set up in the study to find an issue. But not enough researches learn over this question as part of education study, in other words on the process of transmission. Indeed they ignore for instance, if certain contents, certain types of activities, certain forms of studies, certain gestures of education and scholastic shapes are better adapted to the girls than to the boys and conversely. This article is centred on these aspects and more precisely on artefacts used to mediatise the education of technology. The teacher choice of aids is made in mainly for the pedagogic interest which the object gives. Is the pedagogic interest balanced from the point of view of the question of gender if artefacts introduced in class favour objects which are, in social life, mainly used by men, women or both?     

The effects of an articulated customer value proposition (CVP) on promotional expense,brand investment and firm performance in B2B markets: A text based analysis

Using text-based analysis, we search for evidence of articulated customer value propositions (CVP), in annual reports of US B2B firms, and then demonstrate that B2B firms that explicitly emphasize a CVP invest more in their brands, have higher future sales and sales per customer. We also find that CVP has a negative effect on the size of their customer base, perhaps because firms who care about a CVP appear to attract more long-term, loyal customers. Firms that pay more attention to CVP also tend to spend less on advertising and promotion. Future performance, particularly among small to mid-size firms, is positively affected when these firms emphasize CVP, and this also holds especially in less competitive markets. Our findings are based on a large dataset of around 12,000 firm year observations for a 14-year period from 2004 to 2017.     

A preliminary study into the investigation of the prediction of craftmanship skills in children

Psychometric and physical data were investigated as predictors of six different craftmanship skills in a sample of 290 children (Female = 131; Male = 159), at age 12 + in a Manchester comprehensive school. The results of regression analysis indicate that certain craftmanship skills can be predicted by reference to specified cognitive and physical measures. Only one of the craftmanship skills (transverse error in making a saw cut) was shown to be related to the sex of the child, boys being more accurate than girls.     

Married to the firm? A large‐scale investigation of the social context of ownership

Research summary : Using a large sample of private firms across Europe, we examine how the social context of owners affects firm strategy and performance. Drawing on embeddedness theory and the institutional logics perspective, we argue that embeddedness in a family, in particular the nuclear family, can strengthen identification and commitment to the firm, but can also induce owners to behave more conservatively. Consistent with this argument, we find that family‐owned firms have higher profit margins, returns on assets, and survival rates compared to single‐owner or unrelated‐owners' firms, but also invest and grow more slowly, hold greater reserves of cash, and rely less on external debt. These differences are most pronounced when the two largest shareholders are married. Our results highlight the key role of marital ties in explaining differences in behavior and performance among firms. Managerial summary : Despite the prevalence of the married‐couple ownership structure in firms, little research has been dedicated to understanding how these firms are managed and perform. We examine the behavior and performance of firms owned by married couples in a large panel of closely held Western European firms. We find that married‐owner family firms are managed more conservatively relative to firms with unrelated owners and even to other family‐owned firms. In particular, married‐owner family firms invest and grow more slowly and rely less on external finance. However, they also exhibit greater performance stability and higher profitability. Our findings suggest that social relationships among owners have a large impact on firm strategy and performance, and highlight some potential trade‐offs to performance when married couples control firms.

Teaching and learning the nature of technical artifacts

Artifacts are probably our most obvious everyday encounter with technology. Therefore, a good understanding of the nature of technical artifacts is a relevant part of technological literacy. In this article we draw from the philosophy of technology to develop a conceptualization of technical artifacts that can be used for educational purposes. Furthermore we report a small exploratory empirical study to see to what extent teachers’ intuitive ideas about artifacts match with the way philosophers write about the nature of artifacts. Finally, we suggest a teaching and learning strategy for improving (student) teachers’ concepts of technical artifacts through practical activities.     

Assessing South Africa Learners’ Attitudes Towards Technology by Using the PATT (Pupils’ Attitudes Towards Technology) Questionnaire

The PATT (Pupils’ Attitude Towards Technology) questionnaire, as validated for the USA, was used to assess and analyse South African learners’ attitudes towards technology. The responses of 500 girls and 510 boys, from the Gauteng Province in South Africa, were analysed using a principal component and a principal factor analysis. The explained variance was rather low and indicated that the questionnaire needed adaptation for the South African context. The outcomes of the research were positive in that there were no significant differences regarding the gender attitudes that ‘technology should be for all’ and that ‘technology makes contributions to society’. The fact that girls have a stronger gender discrimination view related to themselves regarding technology needs to be addressed in future curriculum development issues. This revised version was published online in July 2006 with corrections to the Cover Date.     

Student Access to Apprenticeships: Evidence from a Vignette Experiment

We identify the causal effects of student characteristics on the likelihood of being hired for an apprenticeship and explore the mechanisms underlying the employer’s decision. To this end, we perform a vignette experiment among human resources professionals in Belgium, focusing on less-qualified youth. Our results indicate that students with favorable educational records and students revealing being motivated are more likely to obtain an apprenticeship. Furthermore, we find that these characteristics are used by human resources professionals as signals of trainability, employability, and quit intentions.     

Learning to collaborate through collaboration: How allying with expert firms influences collaborative innovation within novice firms

Research summary : Strategic alliances have been recognized as a means for firms to learn their partners' proprietary knowledge; such alliances are also valuable opportunities for partner firms to learn tacit organizational routines from their counterparts. We consider how relatively novice technology firms can learn intraorganizational collaborative routines from more experienced alliance partners and then deploy them independently for their own innovative pursuits. We examine the alliance relationships between Eli Lilly & Co. (Lilly), a recognized expert in collaborative innovation, and 55 small biotech partner firms. Using three levels of analysis (firm, patent, and inventor dyad), we find that greater social interaction between the partner firm and Lilly subsequently increases internal collaboration among the partner firm's inventors. Managerial summary : Can collaborating externally advance internal collaboration? Yes. Our research found that collaboration among scientists at small, early‐stage biotechnology firms significantly increased after these firms formed highly interactive R&D alliances with a large pharmaceutical company known for its expertise in such collaboration. It is well known that alliances help new firms learn specific new technologies and commercialize innovations. Our study broadens the scope of potential benefits of alliances. New firms can also learn collaboration techniques, deploying them internally to enhance their own abilities in collaborative innovation. Managers should take this additional benefit into consideration in developing their alliance strategies. Pursuing alliance partners with expertise in collaboration and keeping a high level of mutual interactions with partner firm personnel should be important considerations to extract this value.

Aid,collective action and benefits to smallholders: Evaluating the World Food Program's purchase for progress pilot

Agricultural commodity markets in developing countries often operate in a constrained environment of prohibitive transaction costs. Consequently, smallholder farmers are only partly integrated into these markets, a situation that keeps them in a lower level of development equilibrium (poverty trap). Although cooperative institutional alternatives such as Farmers’ Organizations (FOs) may reduce transaction costs and revitalize agricultural production and commercialization, they rarely have been successful in fully delivering on these promises. Against this backdrop, the World Food Programmed (WFP) has recently implemented a multi-year and multi-country pilot to increase smallholder participation in commodity markets. The projects involved investing in physical and human capacities of Farmer Organizations (FOs) to aggregate commodities and add value, as well as locally purchasing food aid from the same. The combination of interventions was expected to increase the relative price of agricultural products, particularly staple crops. In this study, using Ethiopian panel survey data, we estimated the causal income and investment effects of the Ethiopian P4P intervention among smallholders. Using an entropy balancing (EB) model and semi-parametric difference-in-difference (DID) model, we show that the P4P intervention has increased per capita consumption by smallholders. Our additional analysis confirms that this effect is heterogeneous owing to elite capture within Farmer Organizations. We also find evidence of increased food consumption scores, increased investments in child schooling, and increased asset holding among program-participating smallholders relative to comparison farmers. Policy implications are discussed.     

Communication practices in a business relationship: Creating,relating and adapting communication artifacts through time

The purpose of this paper is to re-examine the task-media fit model of communications by adopting an interactive approach and thus taking into account the influence of time. Task-media fit is manifest in communication artifacts such as emails, minutes of meetings, reports or flowcharts. Task-media fit theory holds that when communication tasks (e.g. sharing sales data, work-in progress reports or technical data) are matched with the appropriate media (e.g. email, text, face-to-face), a more effective communication is likely to occur at that moment in time. By adopting a multi-methods approach, this longitudinal study explores how communication practices shape a new business relationship. Our findings show how different forms of time (horizontal, vertical, standardized, and planned time) interact and are variously privileged in complex task-media fit judgments. Findings show how task-media fit judgments change as they unfold over time, stabilizing to create communication norms that then become disrupted by critical events. Communication artifacts are emergent and relational, to what has gone before and what is intended to come next.     

How to leverage the impact of R&D on product innovation? The moderating effect of management innovation

Although research and development (R&D) is a key indicator of (technological) innovation, scholars have found mixed results regarding its effect on product innovation and firm performance. In this paper, we claim that variations in R&D effectiveness can be explained by changes in a firm’s social system, in particular in its management innovation. It is still unclear how management innovation influences R&D effectiveness in terms of product innovation. In this study, we address this theoretical and empirical gap in the innovation literature. Our theoretical arguments and findings from a large-scale survey among Dutch firms show that R&D has a decreasingly positive relationship with product innovation, particularly for firms with low levels of management innovation. However, in firms with high levels of management innovation, this relationship becomes more J-shaped, especially in small and medium-sized firms. Our findings also appear to indicate that management innovation may be more important for competitive advantage than just R&D. Overall, our insights reveal that management innovation is a key moderator in explaining firms’ effectiveness in transforming R&D into successful product innovation.
