Research on Scaling Up Evidence-Based Instructional Practice: Developing a Sensitive Measure of the Rate of Implementation

Few evidence-based instructional practices achieve large-scale use, often remaining only in the schools directly involved in their development. Research on scaling up effective educational practice often lacks sensitive measures of the practice's implementation and the required research protocol. This article describes how we used rate of implementation as a sensitive measure to help identify barriers to implementation of class-wide peer tutoring (CWPT). Using communication technologies and a learning management system, we monitored the rate of CWPT implementation and its research protocol across nine schools in five states. Rate of implementation was defined as the number of weeks in which a school successfully completed the 12 implementation tasks required to reach full implementation. We discuss factors related to the variation in implementation rate (30-50 weeks) between schools, and implications of this measurement strategy for research on instructional practices and the technology used to facilitate scalability research.     

Primary humanities – a perspective from Northern Ireland

ABSTRACT

The word ‘humanities’ does not appear in the current Northern Ireland Curriculum (NIC). Geography and history are taught within an Area of Learning called ‘The World Around Us’ which also contains science and technology. The curriculum has a strong emphasis on an integrated, ‘connected learning’ way of teaching and learning. Religious Education is a separate subject that stands alongside, rather than within, the NIC, and the curriculum also includes a new Area of Learning – ‘Personal Development and Mutual Understanding’. The distinctive content and modes of teaching which the humanities subjects tend to encourage ought to be seen as particularly important in Northern Ireland – a part of the UK which has endured a complicated past and remains to a large extent segregated, both socially and educationally. This complicated past means that there is often wariness and reluctance on the part of teachers towards tackling controversial personal and social issues in the primary school.     

The BASES expert statement on exercise therapy for people with chronic kidney disease

Chronic kidney disease (CKD) is becoming a serious health problem throughout the world and is one of the most potent known risk factors for cardiovascular disease, which is the leading cause of morbidity and mortality in this patient population. Physical inactivity has emerged as a significant and independent risk factor for accelerated deterioration of kidney function, physical function, cardiovascular function and quality of life in people in all stages of CKD. CKD specific research evidence, combined with the strong evidence on the multiple health benefits of regular and adequate amounts of PA in other cardiometabolic conditions, has resulted in physical inactivity being identified by national and international CKD clinical practice guidelines as one of the multiple risk factors that require simultaneous and early intervention for optimum prevention/management of CKD. Despite this realisation, physical inactivity is not systematically addressed by renal care teams. The purpose of this expert statement is therefore to inform exercise and renal care specialists about the clinical value of exercise therapy in CKD, as well as to provide some practical recommendations on how to more effectively translate the existing evidence into effective clinical practice.     

National Guidelines for the Performance of the Sweat Test in Diagnosis of Cystic Fibrosis on behalf of the Croatian Society of Medical Biochemistry and Laboratory Medicine and the Cystic Fibrosis Centre - Paediatrics and adults,University Hospital Centre Zagreb

The sweat test (ST) is a cornerstone in the diagnosis of cystic fibrosis (CF), together with newborn screening and genetic testing. However, the performance of the ST can depend on the operator’s skill, so several international guidelines have been published to standardise the ST, but inconsistencies remain. The joint Working Group for ST Standardisation (WG STS) of the Croatian Society of Medical Biochemistry and Laboratory Medicine, in association with cistic fybrosis health professional and the Cistic Fibrosis Centre for Paediatrics and Adults, have issued National Guidelines for the Performance of the Sweat Test in order to ensure consistency in ST performance and accuracy of reported results. Many of the standards were taken from the 2nd Edition of the UK Guidelines for Performance of the ST for the Diagnosis of CF, while others were taken from independent consensus statements from the WG STS based on local ST equipment and practices. The standards cover every step of the ST, from the indications for testing to reporting of results and their interpretation, including the analytical phase and quality control. In addition, National Guidelines include appendices with practical examples in order to aid implementation of the recommendations in routine practice.     

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.     

PROFESSOR “X”: HOW EXPERTS RATED HIS STUDENT RATINGS

This paper attempts to place the reader in the situation of interpreting data on the evaluation by students of a fellow member of faculty (staff). The comments of the evaluators reveal a widespread divergence of views, but they rarely seem to question the purpose of the exercise.     

Intensity of exercise recovery,blood lactate disappearance,and subsequent swimming performance

Abstract

The aim of this study was to examine the effects of active versus passive recovery on blood lactate disappearance and subsequent maximal performance in competitive swimmers. Fourteen male swimmers from the University of Virginia swim team (mean age 20.3 years, s = 4.1; stature 1.85 m, s = 2.2; body mass 81.1 kg, s = 5.6) completed a lactate profiling session during which the speed at the lactate threshold (V_LT), the speed at 50% of the lactate threshold (V_LT.5), and the speed at 150% of the lactate threshold (V_LT1.5) were determined. Participants also completed four randomly assigned experimental sessions that consisted of a 200-yard maximal-effort swim followed by 10 min of recovery (passive, V_LT.5, V_LT, V_LT1.5) and a subsequent 200-yard maximal effort swim. All active recovery sessions resulted in greater lactate disappearance than passive recovery (P < 0.0001 for all comparisons), with the greatest lactate disappearance associated with recovery at V_LT (P = 0.006 and 0.007 vs. V_LT.5 and V_LT1.5 respectively) [blood lactate disappearance was 2.1 mmol · l^?1 (s = 2.0), 6.0 mmol · l^?1 (s = 2.6), 8.5 mmol · l^?1 (s = 1.8), and 6.1 mmol · l^?1 (s = 2.5) for passive, V_LT.5, V_LT, and V_LT1.5 respectively]. Active recovery at V_LT and V_LT1.5 resulted in faster performance on time trial 2 than passive recovery (P = 0.005 and 0.03 respectively); however, only active recovery at V_LT resulted in improved performance on time trial 2 (TT₂) relative to time trial 1 (TT₁) [TT₂?TT₁: passive +1.32 s (s = 0.64), V_LT.5+1.01 s (s = 0.53), V_LT?1.67 s (s = 0.26), V_LT1.5?0.07 s (s = 0.51); P < 0.0001 for V_LT). In conclusion, active recovery at the speed associated with the lactate threshold resulted in the greatest lactate disappearance and in improved subsequent performance in all 14 swimmers. Our results suggest that coaches should consider incorporating recovery at the speed at the lactate threshold during competition and perhaps during hard training sessions.     

Using the Quality of Literacy Implementation Checklist to Improve Preschool Literacy Instruction

Despite much progress in improving the quality of preschool programs, there is still an uneven quality of instruction in early childhood settings. Providing support and professional development (PD) for teachers that is practical, systematic and sustainable is one potential avenue to increase classroom quality in preschool, including quality of literacy instruction. Preschool educators who want to focus on increasing the quality of literacy instruction need simple-to-use tools that can be implemented quickly and provide a means to assess progress towards the goal of improving literacy instruction. The Quality of Literacy Implementation checklist measures how well the teaching staff include intentional, instruction in literacy/oral language. Rather than focusing on a specific curriculum or intervention, quality of implementation focuses on the teacher’s delivery of key procedural features of evidence-based instruction. As is the case with fidelity of implementation, a quality of implementation checklist not only measures implementation but also provides a roadmap about how instruction might be modified to ensure that critical and essential skills are emphasized across the preschool day.
