In any visual search task in the lab or in the world, observers will make errors. Those errors can be categorized as "deterministic": If you miss this target in this display once, you will definitely miss it again. Alternatively, errors can be "stochastic", occurring randomly with some probability from trial to trial.…

Modern societies need higher education systems that are strongly grounded on scientific knowledge and evidence-based teaching tools. This laboratory-based study extended Chase and Houmanfar (2009), examining the effects of basic and elaborate feedback on participants' performance measured with two sets of tests administered after a college-level…

Behavioral and electrophysiology studies have shown that humans possess a certain self-awareness of their individual timing ability. However, conflicting reports raise concerns about whether humans can discern the direction of their timing error, calling into question the extent of this timing awareness. To understand the depth of this ability,…

One of the most serious forms of cheating occurs when examinees have item preknowledge and prior access to secure test material before taking an exam for the purpose of obtaining an inflated test score. Examinees that cheat and have prior knowledge of test content before testing may have an unfair advantage over examinees that do not cheat. Item…

The current study expands on previous research on gender differences and similarities in science test scores. Using three different approaches -- differential item functioning, differential distractor functioning, and decision tree analysis -- we examine a high school science assessment administered to 3,849 10th-12th graders, of whom 2,021 are…

Reliability is the consistency of a set of scores that are designed to measure the same thing. Reliability is a statistical property of scores that must be demonstrated rather than assumed.

With the iPad-mediated cognitive assessment gaining popularity with school districts and the need for alternative modes for training and instruction during this COVID-19 pandemic, school psychology training programs will need to adapt to effectively train their students to be competent in administering, scoring, an interpreting cognitive…

Achievement tests are used to make high-stakes (e.g., special education placement) decisions, and previous research on norm-referenced assessment suggests that errors are ubiquitous. In our study of 42 teacher trainees, utilizing five of the six core subtests of the Kaufman Test of Educational Achievement, Third Edition (KTEA-3), we found that…

Individuals trained in the use of cognitive tests should be able to complete an assessment without making administrative, scoring, or recording errors. However, an examination of 295 Wechsler protocols completed by graduate students and practicing school psychologists revealed that errors are the norm, not the exception. The most common errors…

Successfully retrieving information protects it against later forgetting. Failed retrieval attempts are also beneficial if followed by study of corrective feedback. To explain both of these findings, researchers have proposed the "mediation hypothesis." In the case of learning from corrective feedback, initial errors may serve as…

This study aims to systematically evaluate the scoring errors made by psychologists in training, in the hopes of providing strong, empirically based guidelines to training programs. Survival analysis was used to determine the number of attempts required for graduate students to achieve proficiency in scoring standardized record forms from the…

In recent years, there has been increasing focus on the issue of multiple hypotheses testing in education evaluation studies. In these studies, researchers are typically interested in testing the effectiveness of an intervention on multiple outcomes, for multiple subgroups, at multiple points in time or across multiple treatment groups. When…

One of the highest ambitions in educational technology is the move towards personalized learning. To this end, computerized adaptive learning (CAL) systems are developed. A popular method to track the development of student ability and item difficulty, in CAL systems, is the Elo Rating System (ERS). The ERS allows for dynamic model parameters by…

This study reports on the development, validation, and administration of a 48-item multiple-choice test to assess students' representational fluency of linear functions in a physics context (1D kinematics) and a mathematics context. The test includes three external representations: graphs, tables, and formulas, which result in six possible…

This article reports on a Monte Carlo simulation study, evaluating two approaches for testing the intervention effect in replicated randomized AB designs: two-level hierarchical linear modeling (HLM) and using the additive method to combine randomization test "p" values (RTcombiP). Four factors were manipulated: mean intervention effect,…
