The Issue of Range Restriction in Bookmark Standard Setting

This article uses data from a large‐scale assessment program to illustrate the potential issue of range restriction with the Bookmark method in the context of trying to set cut scores to closely align with a set of college and career readiness benchmarks. Analyses indicated that range restriction issues existed across different response probability (RP) values and item response theory (IRT) models if one were to apply the Bookmark procedure using intact test forms. Results also suggested that range restriction may still be present if one had access to additional data from an item bank. This demonstration critically highlights challenges that may exist in some practical applications of the Bookmark method due items not being designed to cover the full range of examinee abilities.

Effects of load mass carried in a backpack upon respiratory muscle fatigue

Purpose: The purpose of this study was to investigate whether loads carried in a backpack, with a load mass ranging from 0 to 20?kg, causes respiratory muscle fatigue. Methods: Eight males performed four randomised load carriage (LC) trials comprising 60?min walking at 6.5?km?h^?1 wearing a backpack of either 0 (LC₀), 10 (LC₁₀), 15 (LC₁₅) or 20?kg (LC₂₀). Inspiratory (P_Imax) and expiratory (P_Emax) mouth pressures were assessed prior to and immediately following each trial. Pulmonary gas exchange, heart rate (HR), blood lactate and glucose concentration and perceptual responses were recorded during the first and final 60?s of each trial. Results: Group mean P_Imax and P_Emax were unchanged following 60-min load carriage in all conditions (p?>?.05). There was an increase over time in pulmonary gas exchange, HR and perceptions of effort relative to baseline measures during each trial (p?p?>?.05). Conclusions: These findings indicate that sub-maximal walking with no load or carrying 10, 15 or 20?kg in a backpack for up to 60?min does not cause respiratory muscle fatigue despite causing an increase in physiological, metabolic and perceptual parameters.
