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.

Context: Automatically generating test suites is intrinsically a multi-objective problem, as any of the testing targets (e.g, statements to execute or mutants to kill) is an objective on its own. Test suite generation has peculiarities that are quite different from other more regular optimisation problems. For example, given an existing test suite, one can add more tests to cover the remaining objectives. One would like the smallest number of small tests to cover as many objectives as possible, but that is a secondary goal compared to covering those targets in the first place. Furthermore, the amount of objectives in software testing can quickly become unmanageable, in the order of (tens/hundreds of) thousands, especially for system testing of industrial size systems. Objective: To overcome these issues, different techniques have been proposed, like for example the Whole Test Suite (WTS) approach and the Many-Objective Sorting Algorithm (MOSA). However, those techniques might not scale well to very large numbers of objectives and limited search budgets (a typical case in system testing). In this paper, we propose a novel algorithm, called Many Independent Objective (MIO) algorithm. This algorithm is designed and tailored based on the specific properties of test suite generation. Method: An empirical study was carried out for test suite generation on a series of artificial examples and seven RESTful API web services. The \evo system test generation tool was used, where MIO, MOSA, WTS and random search were compared. Results: The presented MIO algorithm resulted having the best overall performance, but was not the best on all problems. Conclusion: The novel presented MIO algorithm is a step forward in the automation of test suite generation for system testing. However, there are still properties of system testing that can be exploited to achieve even better results. [less ▲]

An important aim in software testing is constructing a test suite with high structural code coverage – that is, ensuring that most if not all of the code under test has been executed by the test cases comprising the test suite. Several search-based techniques have proved successful at automatically generating tests that achieve high coverage. However, despite the well-established arguments behind using evolutionary search algorithms (e.g., genetic algorithms) in preference to random search, it remains an open question whether the benefits can actually be observed in practice when generating unit test suites for object-oriented classes. In this paper, we report an empirical study on the effects of using evolutionary algorithms (including a genetic algorithm and chemical reaction optimization) to generate test suites, compared with generating test suites incrementally with random search. We apply the EVOSUITE unit test suite generator to 1,000 classes randomly selected from the SF110 corpus of open source projects. Surprisingly, the results show that the difference is much smaller than one might expect: While evolutionary search covers more branches of the type where standard fitness functions provide guidance, we observed that, in practice, the vast majority of branches do not provide any guidance to the search. These results suggest that, although evolutionary algorithms are more effective at covering complex branches, a random search may suffice to achieve high coverage of most object-oriented classes.

We consider the inventory decision of a retailer facing strategic customers. We develop a behavioral theory that accounts for reference dependence, which makes predictions on how the presence of strategic customers leverages retailer behavior. Specifically, the reference-dependent retailer shall decrease her order quantity when there are more strategic customers in the population. As such, the conventional pull-to-center bias for newsvendor is generalized, since the presence of strategic consumers may induce the retailer to pull her order further below the center even when the production cost is low. Furthermore, increasing proportion of strategic customers reduces the retailer's ordering bias under low cost, yet amplifies it when the cost is high. Our subsequent experiments find pull-below-center effect, validate the theoretical predictions, and establish the asymmetry of reference dependence with the estimated behavioral parameters. We also study extensions to our model and carry out robustness checks of our experimental results. [less ▲]
