on the equivalence of constructed-response and multiple-choice : stem-equivalent, stem non-equivalent but content equivalent, and stem and content non-equivalent items in reading comprehension using multifaceted rasch
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...

et al. (1991), and has since been utilized by several researchers (Tarara and Ham, 1997; Ren et al., 1999; The dual-probe heat-pulse (DPHP) technique is emerging as a Song et al., 1999; Campbell et al., 2002). These studies useful technique for measuring soil volumetric water content ( ). have shown that the DPHP technique can provide accuHowever, few published data are available regarding the ...

to evaluate the level of accuracy and precision that can be achieved with the DPHP method. Tarara and Ham The dual-probe heat-pulse (DPHP) method provides a means of (1997) conducted a laboratory experiment in which estimating volumetric soil water content ( ) and change in volumetric water content ( ) from measurements of volumetric heat capacity. DPHP-based estimates were compared with values...
