Views of Coaching Practice Expressed by School-Based Coaches

This study reports on the views of coaching expressed by school-based coaches and coaching experts in response to observing the practice of a novice coach featured in a video. Researchers hypothesized that a coach participant\u27s observations about another coach\u27s practice would be a useful tool for examining participants\u27 beliefs about coaching. Researchers compared responses from school-based coaches to the responses of coaching experts and views expressed in leading coaching literature in order to examine the variation in school-based coaches\u27 views. Analysis of responses from both practicing coaches and coaching experts revealed eight themes that describe components of the videotaped coaching cycle: 1) coaching relationships; 2) the use of praise by the coach; 3) discussions of student learning; 4) how coaches respond to teachers\u27 questions; 5) how coaches prompt reflection; 6) how coaches address teacher knowledge and learning; 7) discussions of mathematics content; and, 8) facilitation of the coaching session. The analysis also revealed that these themes correspond to accepted domains of coaching knowledge reported in the coaching literature

ACCREDITATION AS A FRAMEWORK FOR SCHOOL IMPROVEMENT: A QUANTITAVITE STUDY

This study investigated the perceptions of heads of schools from accredited schools concerning whether the accreditation process, as prescribed by the League of Christian Schools (LCS), leads to improvement in leadership capacity and the impact of instruction on the learning environment. The League of Christian Schools has developed an accreditation process that is based in systems theory as espoused by Senge (2006), which contributed to the theoretical framework for this study. Administrators in LCS member K12 schools provided 25 responses to an anonymous online survey. Quantitative data were collected and analyzed to determine perceptions regarding increased organizational capacities in the years following initial accreditation. The major finding of this research study is the strong belief by Christian school administrators that the LCS accreditation process has improved the school over time. The mean score perceptions regarding the effect accreditation has on leadership capacity was 4.22, which was statistically significant (t (24) = 11.91; p \u3c .001) with a huge effect (d = 2.38). Concerning Leadership Capacity, eighty percent (80%) responded that they agreed (50.9%) or strongly agreed (37.1%) that the accreditation process increased leadership capacity. Concerning Instructional Capacity, a one sample t test showed statistical significance (t (24) = 9.99; p \u3c .001) of study participant mean score of 4.20 when asked about improved instruction. The effect was huge (d = 2.00). For perceptions of the impact of accreditation on the instructional program, over eighty-six percent (86.5%) either agreed (49.5%), or strongly agreed (37.1%) to instructional improvement

An Examination into the Relationship Between Iron Deficiency and Postpartum Depression

Postpartum depression is recognized as the most common complication of childbearing; however, its etiology remains fairly undetermined. Many different influences have been hypothesized as to what may cause postpartum depression, including changes in levels of various hormones (such as estrogen and progesterone), a decrease in serotonin, low levels of vitamin D, social factors, and iron deficiency. The lack of strong evidence for one specific cause makes it fairly clear that there are many factors that play a role in the development of postpartum depression. Iron deficiency is one issue that is thought to contribute to the development of postpartum depression due to iron’s role of oxygenating the brain, as well as in the synthesis of some neurotransmitters and enzymes in the nervous system. Therefore, iron deficiency can result in decreased oxygenation of the brain tissue, which can result in depression symptoms, and it can also decrease the number of certain neurotransmitters that are linked to depression

A simulation model for wind energy storage systems. Volume 2: Operation manual

A comprehensive computer program (SIMWEST) developed for the modeling of wind energy/storage systems utilizing any combination of five types of storage (pumped hydro, battery, thermal, flywheel, and pneumatic) is described. Features of the program include: a precompiler which generates computer models (in FORTRAN) of complex wind source/storage/application systems, from user specifications using the respective library components; a program which provides the techno-economic system analysis with the respective I/O the integration of system dynamics, and the iteration for conveyance of variables; and capability to evaluate economic feasibility as well as general performance of wind energy systems. The SIMWEST operation manual is presented and the usage of the SIMWEST program and the design of the library components are described. A number of example simulations intended to familiarize the user with the program's operation is given along with a listing of each SIMWEST library subroutine

Ursodeoxycholic acid improves bilirubin but not albumin in primary biliary cirrhosis: further evidence for nonefficacy.

BACKGROUND/AIM: In randomised controlled trials (RCTs) of ursodeoxycholic acid (UDCA), although serum bilirubin is frequently reduced, its effect on disease progression and mortality is unclear. As serum albumin is an established independent prognostic marker, one might expect less deterioration of serum albumin values in a UDCA-treated group. We therefore modelled the typical evolution of serum bilirubin and albumin levels over time in UDCA-untreated patients and compared it with the observed levels in UDCA RCTs. METHODS: Multilevel modelling was used to relate the evolution of serum albumin to serum bilirubin and time since patient referral. For each considered RCT, the derived model was used to predict the relationship between final mean serum albumin and bilirubin concentration, adjusted for mean serum albumin at referral and followup duration. RESULTS: Five RCTs were eligible in terms of available data, of which two had long followup. In all trials, serum albumin did not significantly differ between UDCA- and placebo-treated patients, despite the UDCA effect on serum bilirubin. Therefore, there is no evidence over time for changes or maintenance of albumin levels for UDCA-treated patients above the levels predicted for placebo-treated patients. CONCLUSIONS: Our findings suggest that UDCA does not alter serum albumin in a way that is consistent with its effect on serum bilirubin. Therefore, reductions in serum bilirubin of UDCA-treated PBC do not parallel another validated and independent prognostic marker, further questioning the validity of serum bilirubin reduction with UDCA as a surrogate therapeutic marker

Pre-service Teachers in Mathematics Lesson Study

This paper presents qualitative evidence to answer the questions, “What are the outcomes of engaging pre-service and in-service teachers in a collaborative lesson study experience” and “How can the outcomes of this experience inform future ways to include preservice teachers in lesson study?” The data gathered demonstrate that including pre-service teachers in lesson study can introduce them to lesson-building as a process and cross-grades teacher collaboration. It can give them opportunities to be critical thinkers in the context of mathematics education and encourages them to think as teachers. One weakness the pre-service teachers demonstrated was an incomplete understanding of the appropriate use of technology in algebra. Consideration of prior knowledge and anticipation of student responses was lacking among both pre-service and in-service teachers. Overall, the data show that pre-service teachers can contribute to the lesson study process as researchers
