For the World in Which They Will Be Living

To examine the antecedents of perceptions of grading fairness, approximately 600 college students were surveyed about the prevalence and desirability of 1) teaching practices that assisted students to prepare for examinations, and 2) common test scoring manipulations used to transform poor scores into acceptable ones (e.g., curving low scores upward). Students also described the fairness of the grading they had experienced. Regression analysis revealed that grading fairness was predicted best by exposure to the teaching practices rather than the scoring practices. Results are discussed in terms of the possible effects of these teaching and grading practices on grade inflation.

Two-step control grading method

The incorrectness of function grading in value engineering has been an essential problem for decades. This paper proposes a new method, where the functions under consideration are ranked in queue according to their importance and then graded quantitatively. By using this method, the reviewers are more aware of the degrees of importance, and therefore will have an easier time grasping the standard and reducing the erroneous grading. In the first step, the sign test is used to discard incorrect data, to count the grading result and to arrange in queue according to the degrees of functional importance. In the second step the queued up functions undergo quantitative grading, where the “average value of fluctuation coefficient” is proposed to determine the control levels and to delete unreasonable data outside the controlled region so as to get more satisfactory grading value. The proposed method solves the problem of the incorrectness of function grading in value engineering. It has been proved that the correctness has been raised from the original 70% to over 95%. This new method is not only contributive to the discipline of value engineering but also suitable in the evaluation of technical economy.     

Grading Standards,Student Ability and Errors in College Admission

Grades are important for admission of students in most higher education programs. Analyzing admission and student performance data at a major Norwegian business school, we find that the grading practice of teachers at regional colleges sending students to the school is affected by the average performance of the students being graded. Teachers at colleges recruiting good students from upper secondary school tend to be strict in their grading practice, while teachers at colleges recruiting less good students tend to follow a lenient practice. This has implications for the interpretation of grades and hence for optimal admission procedures. We develop a methodology to assess the consequences of differential grading standards. Approximately 10% of the students in our data are admitted at the expense of more competent students. We demonstrate costs for the school admitting the wrong students and in particular for the rejected students.

Questioning Points and Percentages: Standards-Based Grading (SBG) in Higher Education

Despite its growing use at the K–12 level, standards-based grading (alignment of grading to course standards) has been comparatively neglected in higher education. College students are often confronted with grading practices that reflect subjective, non-standardized formats incorporating a blend of academic and non-academic components. This case study examined student attitudes and experiences regarding standards-based grading (SBG) principles introduced in an educational technology course in a medium-sized, Midwestern university. The authors found that, while students were initially anxious about the paradigm shift and the additional work it would entail, they nevertheless viewed the model as clearer and more fair. As the study progressed, students reported moving beyond “playing the game” of earning points for a grade and actually engaging more substantively with course content. Based on regular formative feedback, students began to take more ownership of their learning. Ultimately, most participants found SBG more beneficial and defensible—and reflective of their knowledge—than traditional grading practices. To supplement these findings, the authors offer some implementation ideas to assist instructors who may want to begin using SBG in their courses, including reflecting on and clarifying their purpose for grading, ensuring that their grades have meaning (by communicating information that is accurate, meaningful, and relevant to student success), and allowing students multiple chances to demonstrate learning (if the purpose of grading and assessment is to encourage and report mastery).
