Common Challenges and Experiences of School Districts That Are Implementing One-to-One Computing Initiatives

This article explores the implementation of various K–12 one-to-one computing initiatives to determine if patterns exist. These initiatives are funded in times of limited resources and constitute a serious investment in technology for the schools and districts adopting them. The goals of this study were to understand how and why one-to-one computing initiatives are being implemented, how these initiatives are funded and supported, and expectations or assumptions of stakeholders that are driving adoption of this type of technology. The results suggest that these school districts, and those like them, will face many challenges—some financial, some technical, and some procedural—as they work to integrate technology into instruction and assessment. Common themes or challenges identified from this work, and linked with previous research, include leadership and vision, funding, teacher professional development, and project evaluation.

Growing in digital maturity: students and their computers in an academic laptop programme in Singapore

Using data collected through two focus group interviews with 14- to 16-year-olds involved in a one-to-one laptop academic programme in a Singapore secondary school, this paper shows some student disengagement and dissatisfaction in class, and this poses questions about the relevance of the school's laptop programme. Our findings illustrate low productivity in the students' use of their computers as they respond to their teachers' instructional agendas. Our work indicates research into one-to-one laptop learning needs to pay greater attention to the minds, motivations and hands of students as they embark on learning they do not fully understand or can control for themselves. We determine that educators and policy-makers need to know a lot more about how growth in students' digital maturity operates. In the final analysis, we understand and explain the students' views about how their learning experiences might be improved, and their behaviour (as a digital wisdom journey centred on learning) to be digitally mature.     

Examining Differentiation and Utilization of iPads Across Content Areas in an Independent,PreK–4th Grade Elementary School

This mixed methods case study examined the implementation of a 1:1 iPad initiative in a suburban, co-educational, independent, preK–4th grade elementary school in the United States. This article focuses on how teachers used iPads to differentiate instruction and across multiple content areas. Findings show the processes by which teachers employed iPads demonstrated a myriad of teaching and learning opportunities. Overall, teachers integrated iPads into the existing curriculum to complement or enhance their lessons, provide different choices for students to engage with content, or for them to delve deeper into the content. Additionally, iPads were often used in interdisciplinary ways, involving a combination of at least two different content areas during one lesson.     

Homework and Student Math Achievement in Junior High Schools

In the school year 1994/1995 homework characteristics and effectiveness in math education among secondary schools were compared. The study examined the 1st year of secondary education (average age level: 12.3 years). The sample consisted of 28 schools, 56 classes and 1,394 students. The results show a lack of policy directed at the co-ordination of and increase in the amount of homework in Dutch schools. Nevertheless most math teachers give homework every lesson. Multi-level analysis shows that the amount of homework was the only homework variable related to achievement. It explained 2.4% of the variance. Frequency of homework and homework time were not related to achievement. There is a sharp contrast between Dutch and US teachers in ‘checking and grading’ of homework. However, in this study this variable was not related to math achievement.

Co-ordination Within Schools,Commitment of Teachers and Students and Student Achievement

This research study investigates co-ordination strategies within schools, their relationships to both teacher and student commitment to school, and the relationship between student commitment and student achievement in Switzerland. Two different kinds of co-ordination strategies, structural and cultural, can be distinguished. Structural co-ordination strategies have to do with formal, lasting arrangements that allow an organisation to operate. These include roles, rules, procedures, and authority relations. Cultural co-ordination strategies are related to the nature of communications and the consensus on organisational goals in the school. Cultural mechanisms shape what teachers want to do. Drawn from TIMSS, the sample for the present analyses included principals, teachers and students in 178 classes at the lower secondary level in three Swiss cantons: Bale-Country, Berne and Zurich. Multiple regression analyses carried out with different indicators of teacher and student commitment to school showed that school coordination strategies can make a difference, although the effects were rather small. A further analysis that included student commitment indicators as predictors of mathematics achievement suggests that the affective/social and the cognitive domains are relatively independent at class level.

Employment During High School and Student Achievement: Longitudinal Analysis of National Data

Abstract

The relationship between employment and academic performance in a nationally representative sample of U.S. students was examined in a longitudinal study as the students progressed from Grade 8 to 12. The participants (N = 15,552) took part in the base year (1988), first follow-up (1990), and second follow-up (1992) of the National Education Longitudinal Study (NELS). Structural equation modeling was used to analyze the NELS data set while controlling for the effects of family background, previous achievement, gender, and ethnicity. Employment had an overall negative and curvilinear effect on high school GPA. Students who worked fewer than 12 hr per week fared better academically than those students who were not employed. A significant decline in academic performance was observed when students worked more than 11–13 hr per week.
