The Relationship Between Learner Characteristics and Student Outcomes in a Middle School Computing Course: An Exploratory Analysis Using Structural Equation Modeling

This study, which took place during a 7-week middle school computing course, used structural equation modeling to examine the overall cumulative relationship between self-efficacy, interest, and prior computing experience and students’ computer science learning outcomes. The findings indicated that 52% of the variance of student success, measured by a computational thinking quiz and rubric-based evaluations of participants’ computing artifacts, was related to the aforementioned learner characteristics. These findings have implications for theory and practice and suggest that future research and instructional design practice in K–12 computing education should take these learner characteristics into account.     

Factors Influencing New Entrant Dairy Farmer's Decision-making Process around Technology Adoption

Purpose: The aims of this paper are to (1) evaluate the main factors influencing grazing system technology adoption among new entrant (NE) dairy farmers within Europe and the Irish pasture-based dairy industry, and (2) to determine the extent to which economic factors influence decision-making around technology adoption and use among NEs to the Irish dairy industry.

Methodology: Multivariate analysis is used to investigate the associations between region, education level, previous experience in dairy farming, herd size, age and the farmer's perception of the usefulness (PU) and ease-of-use of a technology (PEOU), and the likelihood of that technology being adopted.

Findings: The results of this study identify a high rate of grazing, artificial insemination (AI) and financial management technology adoption among NE dairy farmers whose technology decisions are primarily motivated by financial considerations and are closely related to the PU and PEOU scores of the technology. Grassland measurement had the lowest adoption rate (51%) compared to AI (86%) and farm financial management (84%).

Practical Implications: The substantial importance of PU and PEOU to technology adoption decisions indicates that future research, extension and education programmes should place increased emphasis on the benefits and usability of key technologies in addition to evaluating their scientific merit.

Originality/Value: For the first time information assessing technology adoption amongst new dairy farmers is available. This has the potential to improve and increase extension and education for new dairy farmers in a future post-quota environment.     

Deaf and hard of hearing students' performance on arithmetic word problems

There has been limited research into the intersection of language and arithmetic performance of students who are deaf or hard of hearing, although previous research has shown that many of these students are delayed in both language acquisition and arithmetic performance. The researchers examined the performance on arithmetic word problems of deaf and hard of hearing students in the South-East Queensland region of Australia; they also examined these students' problem-solving strategies. It was found that performance on word problems was similar for deaf and hearing students, but that deaf students experienced delays in achieving successful performance on word problems relative to their hearing peers. The results confirm the findings of other studies showing that students who are deaf or hard of hearing experience delayed language acquisition, which affects their capacity to solve arithmetic word problems. The study conclusions stress the need for greater use of direct teaching of analytic and strategic approaches to arithmetic word problems.     

Catholic education in Zambia: mission integrity and politics

This article provides the history of Catholic state-aided schooling in Zambia for over a century. It notes how the Catholic Church came to view its school to be a pivotal means of church development. By cooperation with the state it entered more fully into the nation’s future by offering high-quality state-sponsored schooling. This proved to engender its acceptance because this is what the younger generation of Zambians treasured. Progressively, the Catholic school faced a major challenge by becoming embedded in a paradigm of learning that ran counter to its religious mission. It will be argued that this dilemma remains and that the future of the Catholic school in Zambia and beyond pivots on a satisfactory outcome if it is to make a distinctive contribution.     

The Critically Designed Garden

This article is concerned with design applied to gardens, using examples from the Chelsea Flower Show in London. There is a discussion of those show gardens that represented Syrian refugees’ gardens in Iraq and the Windrush generation immigration to the UK. The garden designs combine the aesthetics of organic materials and spatial architecture with an implicit critique of topical contemporary social issues. The article concludes by commenting on the risks posed by the reduced and impoverished UK arts education policies for producing the next generation of applied design practitioners.     

Enacting key skills-based curricula in secondary education: lessons from a technology-mediated,group-based learning initiative

Bridge21 is an innovative approach to learning for secondary education that was originally conceptualised as part of a social outreach intervention in the authors’ third-level institution whereby participants attended workshops at a dedicated learning space on campus focusing on a particular model of technology-mediated group-based learning. This paper analyses the current expansion of the Bridge21 project to mainstream schools against a backdrop of government-led reforms for lower secondary education in Ireland. The key skills central to the proposed reforms aim to make education more relevant to the challenges of twenty-first-century living and, among other goals, to empower students to think critically, communicate effectively and work collaboratively. This paper investigates the viability of the Bridge21 model in facilitating the promotion of a selection of these key skills within the context of two case study schools.

Diversity in Broadcast Television: An Empirical Study of Local News

The relation between the structure of a market and the diversity of its product offering has been extensively explored by theorists. We develop 2 measures of diversity and explore the content of local news for 60 stations and 20 designated market areas (DMAs) in the United States. Using a relative station-level diversity metric, ordinary least squares (OLS) estimates imply that relative diversity of local news content decreases as market concentration increases. This result is not, however, robust to an instrumental variables specification. Using a total market diversity metric, the Herfindahl-Hirschman Index (Hirshman, 1964) is significant in OLS and robust to instrumental variable estimation. Because the total market diversity metric is arguably superior to the incremental metric as a measure of overall diversity, this result is useful-it suggests that the total diversity of local news content within a DMA is sensitive to the level of concentration.     

Structural Determinants of Local Public Affairs Place Blogging: Structural Pluralism and Community Stress

This study examines the relationship between community-level characteristics and the presence of public affairs place blogs in 232 U.S. cities. Two models to predict the presence of these sites are tested: a structural pluralism model, which suggests that the presence of one of these sites reflects more pluralistic voices, and a community stress model, which suggests that the presence of these sites reflects citizens’ efforts to cope with community problems. Analysis of demographic and crime data using logistic regression suggests that the community stress model is the stronger predictor. Public affairs place blogs are more likely in cities with higher murder rates, poverty rates, more physical decay, and more residents with professional occupations. It is these residents—with more education and income, living on the periphery of the most affected urban neighborhoods—who are most likely to go online to write about obtrusive community problems.     

Exceptional Research or Why Harry Truman Sought a One-Handed Economist

This article challenges the traditional illustration of the relations between circulation size and advertising rates used by educators. It does so by using a sample of newspapers and explores various regression trendlines and data display of the data obtained from the sample. I find that the relations are best explained by curvilinear rather than linear trendlines and suggest an improved illustration of the relations between advertising price and newspaper circulation.
