Purpose: Oral diadochokinesis (DDK) is a standard dysarthria assessment task. To extract automatic and semi-automatic DDK measurements, numerous DDK analysis algorithms based on acoustic signal processing are available, including amplitude based, spectral based, and hybrid. However, these algorithms have been predominantly validated in individuals…

Assessment of problem-solving skills for preservice teachers is important in science instruction. The purpose of this study is to discover; (a) How are the characteristics of the Problem-Solving Essay Test Instrument (PSETI); (b) How is the validity based on experts assessment; (c) how are the validity and reliability based on trials.

Much of the early research on teachers' knowledge for reading instruction used instruments that primarily emphasized code-based aspects of reading, unintentionally signaling that meaning-focused knowledge is not essential for teaching foundational reading to elementary-age children. In this study, we developed the Knowledge for Enhancing Reading…

The validity of inferences made with test results depends on meeting the assumptions of the test users, one of which is the presumption of optimal performance (i.e., test-takers are doing their best). Flow theory identifies the conditions under which optimal performance is achieved and can be used to inform test users about the degree to which…

Self-determination is a potential predictor of in-school and postschool success, yet it has not previously been examined in youth and young adults who are deaf or hard of hearing (DHH).

We examined the replicability of the 61-item EcoWellness Inventory (EI-61; Reese et al., 2015) and the factor structure of a brief form (i.e., EI-15). The EI-15 demonstrated excellent model fit and initial convergent validity evidence. The inventory serves as a potentially useful tool for assessing ecowellness in professional counseling practice…
