Assessment Bias

Many auditors use an audit methodology that requires a strategic risk assessment of their client's business model as a first step for assessing audit risks. This study examines whether the holistic perspective that auditors acquire in making a strategic risk assessment influences the extent to which they adjust account-level risk assessments when they encounter changes in accounts that are inconsistent with information about client operations. Based on halo theory from the performance evaluation literature, we hypothesize that auditors who (1) perform (do not perform) strategic assessment, and (2) develop favorable (unfavorable) strategic risk assessments, are less (more) likely to adjust account-level risk assessments for inconsistent fluctuations. Data from two laboratory experiments using experienced auditors support both hypotheses. Findings suggest that the halo effect generated during strategic assessment influences judgment by altering auditor tolerance for inconsistent fluctuations.

The Impact

Well-designed laboratories can help students master content and science practices by successfully completing the laboratory experiments. Upper-division chemistry laboratory courses often present special challenges for instruction due to the instrument intensive nature of the experiments. To address these challenges, particularly those associated with rotation style course structures, pre-laboratory videos were generated for two upper-division laboratory courses, Analytical Measurements and Physical Measurements. Sets of videos were developed for each experiment: a pre-laboratory lecture, an experimental, and a data analysis video. We describe the theoretical principles that guided the design of the instructional videos as well as the process. To assess the impact of the videos on students' successful completion of the experiments, a mixed-methods approach to data collection was used, which included video-recorded laboratory observations, student one-on-one interviews, and the Meaningful Learning in the Laboratory Inventory (MLLI) survey. Our findings indicate that video-based resources can help alleviate some challenges associated with rotation-style labs, particularly the temporal disconnect between pre-laboratory lectures and experiment completion as well as the need for more student autonomy in upper-division laboratory courses.

New undergraduate laboratory experiments on induction generators With the increased importance of induction generators in energy conversion from nonconventional sources, it has become necessary to cover this subject extensively at the undergraduate level and offer experiments on it. This paper presents a few undergraduate experiments on induction generators developed at I.I.T. Kharagpur, India.

This article describes a research paradigm for use in undergraduate laboratory experiments on social influence. The method is adapted from White (1975), who compared the responses of control subjects on a survey question to those of experimental subjects who were first exposed to the contrived responses of others to the same question. I review how students in an undergraduate social psychology laboratory use this method, demonstrate the reliability of the influence effect obtained, and discuss the educational value of this research paradigm.
