Effects of small-group reading instruction and curriculum differences for students most at risk in kindergartenL: two-year results for secondary- and tertiary-level interventions

This article describes the implementation of small-group reading instruction as secondary- and tertiary-level components of a three-tier model of prevention and intervention. The study consisted of 83 students who were targeted in the winter of kindergarten as being at high risk for reading failure. Intervention consisted of evidence-based curriculum delivered in groups of one to six students during 30- to 40-min sessions a minimum of three times per week over a 2-year period. Outcome data were collected for early literacy skills, using the Dynamic Indicators of Basic Early Literacy Skills and Woodcock Reading Mastery Test, with comparisons across the different curricula. Results indicated that students in the more directed, explicit intervention groups generally out-performed students in the comparison group. Implications for future research and practice implementing schoolwide three-tier prevention models are discussed.     

Evidence-based decision-making: awareness,process and practice in the management classroom

In an increasingly information rich environment, it is important to teach students decision-making alongside information gathering and management methods. This paper examines the implementation of evidence-based decision-making in a first year introduction to management course at a large university in the Midwestern United States. Students learned decision awareness, decision-making process creation and decision practice alongside areas of management and basic business principles. Students perceived increased skill in decision-making, both individually and in groups. This venture has implications for others looking to help students not only learn experientially, but also improve critical thinking in practice.     

Ascertaining teachers’ perceptions of working with adolescents diagnosed with attention‐deficit/hyperactivity disorder

There are few studies that have directly examined teachers’ perceptions of children with ADHD, particularly children in the adolescent age range. The purpose of this study was to examine the perceptions of general‐education ninth through twelfth grade teachers regarding working with adolescent students with ADHD. Sorted responses from a sample of 100 general‐education high school teachers were analysed and then represented visually using a concept‐mapping technique. The final concept map suggests that teachers perceive adolescents with ADHD along two dichotomies of thematic clusters on an orthogonal axis. Clusters at the top area of the concept map suggest perceptions related to high confidence and willingness, while clusters at the bottom suggest perceptions related to uneasiness and frustration. Clusters along the left side of the concept map suggest perceptions related to behaviour issues, while clusters along the right side suggest perceptions related to classroom teaching issues. Central to the vertical and horizontal dichotomies is a solitary central dimension, which highlights training as an important component of teachers’ perceptions of adolescents with ADHD.     

Imprinting of ducklings to a second stimulus when a previously imprinted stimulus is occasionally presented

Newly hatched ducklings were imprinted to one stimulus and then given prolonged visual exposure to a second discriminable stimulus. Filial behavior toward the second stimulus developed more slowly when the original imprinting stimulus was occasionally presented during exposure to the second stimulus than when the original stimulus was withheld during such exposure. Results were interpreted in terms of a possible motivational aftereffect following presentations of the original imprinting stimulus.     

Risk factors for speech delay of unknown origin in 3-year-old children

One hundred 3-year-olds with speech delay of unknown origin and 539 same-age peers were compared with respect to 6 variables linked to speech disorders: male sex, family history of developmental communication disorder, low maternal education, low socioeconomic status (indexed by Medicaid health insurance), African American race, and prolonged otitis media. Abnormal hearing was also examined in a subset of 279 children who had at least 2 hearing evaluations between 6 and 18 months of age. Significant odds ratios were found only for low maternal education, male sex, and positive family history; a child with all 3 factors was 7.71 times as likely to have a speech delay as a child without any of these factors.     

The effect of computer-mediated collaborative learning on solving III-defined problems

The positive effects of collaborative learning in a face-to-face environment are well known. However, little empirical research exists to determine if such effects transfer to a computer-mediated environment. The purpose of this study was to investigate the effect of computer-mediated collaboration on solving ill-defined problems. Participants first worked through a Web-based instructional program that taught them a four-step problem-solving process. Then they worked in computer-mediated dyads or alone to apply the steps to solve a realistic problem scenario. Results indicated that participants who worked in computer-mediated collaborative dyads performed significantly better than did participants who worked alone. The results also indicated that dyads spent significantly more time than participants in the individual treatment. Both treatment groups had positive attitudes toward working collaboratively, Internet-based instruction, and transfer of problem-solving skills. Implications for the implementation of computer-mediated collaboration in distance learning are discussed. During article preparation, he was a PhD student at Arizona State University (ASU), Tempe.

Upgrading the technological capabilities of foreign transnational subsidiaries in developing countries: The case of electronics in Thailand

Although substantial research shows the importance of transnational corporations (TNCs) to export-led growth in some developing countries, it cannot be assumed that TNC subsidiaries will automatically upgrade their capabilities through time or in a uniform fashion. This paper explores the pattern and pace of a sample of exporting TNC subsidiaries operating in the electronics industry in Thailand, showing how the different architectures of global value chains (centralised versus decentralised) shaped the technological progress of subsidiaries in this country. The case evidence suggests a wide variety in upgrading through time, with some subsidiaries failing to develop capabilities and remaining as ‘assembly only’ plants. Other more dynamic plants developed process engineering and product design skills, investing heavily in capability building. One common determinant in capability building appears to be the overall technology strategy of the global value chain leader (or parent company). In those subsidiaries which did not upgrade beyond assembly, technology decisions and processes were tightly controlled within the parent headquarter locations in relatively centralised international value networks. By contrast, the more dynamic plants exercised more discretion over local capability building. The latter operated in relatively decentralised networks, more open to domestic policies to encourage upgrading. The study suggests that governments should tailor upgrading policies not only according to the approximate level of capabilities attained by local subsidiaries, but also according to how receptive subsidiaries are to upgrading, arguing that capability building and policy receptiveness go hand-in-hand. Other countries hoping to upgrade the quality of foreign direct investment might also wish to focus policies on the more technologically capable, ambitious and receptive categories of foreign subsidiary.     

Teacher, self and peer evaluation of lesson plans written by preservice teachers

The study investigated the effects of three types of evaluation on preservice teachers’ performance, knowledge and attitudes related to writing lesson plans that incorporate technology. Subjects were randomly assigned to one of the three treatment conditions: teacher-evaluation, self-evaluation or peer-evaluation. All groups completed three class periods of instruction on writing lesson plans, then each subject submitted his/her draft lesson plan. The drafts were evaluated by assigned evaluators (teacher, self or peer), who provided scores and written feedback on a 15-item rubric. Students then revised their lesson plans into final form. All three treatment groups improved their lesson plans significantly from draft version to final version, with the teacher-evaluation group showing significantly greater improvement and writing significantly better final lesson plans than each of the other two groups. Teacher-evaluation and self-evaluation groups had significantly higher scores on a knowledge-based posttest than the peer-evaluation group. Several suggestions are discussed for making further improvements in the self-evaluation and peer-evaluation processes.
