A Tablet-Computer-Based Tool to Facilitate Accurate Self-Assessments in Third- and Fourth-Graders

Although student self-assessment is positively related to achievement, skepticism about the accuracy of students’ self-assessments remains. A few studies have shown that even elementary school students are able to provide accurate self-assessments when certain conditions are met. We developed an innovative tablet-computer-based tool for capturing self-assessments of mathematics and reading comprehension. This tool integrates the conditions required for accurate self-assessment: (1) a non-competitive setting, (2) items formulated on the task level, and (3) limited reading and no verbalization required. The innovation consists of using illustrations and a language-reduced rating scale. The correlations between students’ self-assessment scores and their standardized test scores were moderate to large. Independent of their proficiency level, students’ confidence in completing a task decreased as task difficulty increased, but these findings were more consistent in mathematics than in reading comprehension. We conclude that third- and fourth-graders have the ability to provide accurate self-assessments of their competencies, particularly in mathematics, when provided with an adequate self-assessment tool.

The tacit knowledge of entrepreneurial design: interrelating theory, practice and prescription in entrepreneurship research’

An important challenge facing entrepreneurship researchers is the “three-body” knowledge problem of how to use “theoretical knowledge” to produce “prescriptive knowledge” that communicates the “practical knowledge” of situated practice to students and practitioners of entrepreneurship. We argue that a contribution can be made to solving this problem by theorizing practical knowledge as the “know-how” to do a situated entrepreneurial practice. “Know-how” is a cognitive “capacity to act” that prescribes for a practitioner how to produce a type of outcome in a range of circumstances. This “know-how” can potentially, therefore, be reconstructed theoretically as explicit micro-prescriptive guidelines for third-party practice. To exploit this connection between practical knowledge and prescriptive knowledge, however, we first need to overcome the problem that “know-how” is largely tacit in the moment of real-time forward-looking practice. In other words, the practitioner is not directly aware of their tacit “know-how”, or “tacit knowledge”, at the time of practice. In this article, we explore the contribution design theory can make to empirically eliciting, and conceptually inferring, the real-time “tacit knowledge” of entrepreneurial practice as a precursor to producing micro-prescriptive knowledge.

Combinatorial bi-level optimization remains a challenging topic, especially when the lower-level is a NP-hard problem. In this work, we tackle large-scale and combinatorial bi-level problems using GP Hyper-heuristics, i.e., an approach that permits to train heuristics like a machine learning model. Our contribution aims at targeting the intensive and complex lower-level optimizations that occur when solving a large-scale and combinatorial bi-level problem. For this purpose, we consider hyper-heuristics through heuristic generation. Using a GP hyper-heuristic approach, we train greedy heuristics in order to make them more reliable when encountering unseen lower-level instances that could be generated during bi-level optimization. To validate our approach referred to as GA+AGH, we tackle instances from the Bi-level Cloud Pricing Optimization Problem (BCPOP) that model the trading interactions between a cloud service provider and cloud service customers. Numerical results demonstrate the abilities of the trained heuristics to cope with the inherent nested structure that makes bi-level optimization problems so hard. Furthermore, it has been shown that training heuristics for lower-level optimization permits to outperform human-based heuristics and metaheuristics which constitute an excellent outcome for bi-level optimization.
