We report on a series of task-based interviews in which nine mathematicians were asked to evaluate a series of six mathematical arguments, purportedly produced either by fellow mathematicians or undergraduate students. In this paper, we attend to the role of context in mathematicians' responses, leading to four themes in expectations when…

Many language teachers employ collaborative learning within their classrooms. However, expectations surrounding the efficacy of working collaboratively need to be empirically verified. This study employed dynamic assessment to investigate whether learners who are situated within an undergraduate Qatari EFL context learn second language grammatical…

This study investigated the effects of two types of classroom instructions on EFL learners' oral proficiency by implementing teachers' judgment. Two intact classes of EFL university students studied a compulsory subject of their department under two different types of classroom instruction. The first group of students was trained with explicit…

Creativity is an important twenty-first century skill often overlooked in higher education curricula, particularly in the sciences. Students need opportunities to practice and demonstrate their creativity and gain an awareness of the importance of such skills to enhance their graduate capabilities. One way is to embed creativity into course…

Research has shown that collaboratively produced texts are better in quality compared with individually written texts. However, no study has considered the role of collaboration in authorial voice, which is an essential element in current writing curricula. This study analyzes the effects of collaborative task performance in the quality of L2…

The teaching lab is an important component of training and developing undergraduate chemistry students. The lab provides a complex teaching environment where faculty address a number of student-centered goals, including the development of technical proficiency, demonstrations of theoretical concepts, promotion of teamwork, and modeling of data…

Purpose: This study examined bilinguals' performance on functional executive function map tasks such as the Zoo Map from the Behavioural Assessment of the Dysexecutive Syndrome and the extent to which working memory, set-shifting, and inhibition measures predicted bilinguals' performance on these tasks. Additionally, we explored the utility of…

EFL learners often have problems to speak properly in English. As the purpose of teaching speaking is to improve the learners' oral production, language teaching should maximize language use in the classrooms (Haozhang, 1997), which is achieved through implementing proper teaching techniques to require learners to learn and practice the language…

We examined the sequential modulation of congruency effects using a task in which the irrelevant information shares the same stimulus dimensions as the relevant information but is presented at an earlier time. In Experiment 1, sequential modulations were observed within a stimulus modality but not between stimulus modalities. In Experiment 2,…

Two questions about subjective confidence in perceptual judgments are examined: the bases for these judgments and the reasons for their accuracy. Confidence in perceptual judgments has been claimed to rest on qualitatively different processes than confidence in memory tasks. However, predictions from a self-consistency model (SCM), which had been…

A tracking state increases the bandwidth of pen-based interfaces. However, this state is difficult to detect with default visual feedback. This paper reports on two experiments that are designed to evaluate multimodal feedback for pointing tasks (both 1D and 2D) in tracking state. In 1D pointing experiments, results show that there is a…

The backward-compatibility effect (BCE) is a major index of parallel processing in dual tasks and is related to the dependency of Task 1 performance on Task 2 response codes (Hommel, 1998). The results of four dual-task experiments showed that a BCE occurs when the stimuli of both tasks are included in the same visual object (Experiments 1 and 2)…

Many weather forecast providers believe that forecast uncertainty in the form of the worst-case scenario would be useful for general public end users. We tested this suggestion in 4 studies using realistic weather-related decision tasks involving high winds and low temperatures. College undergraduates, given the statistical equivalent of the…

The standardization of loadings gives a metric to the corresponding latent variable and thus scales the variance of this latent variable. By assigning an appropriately estimated weight to all the loadings on the same latent variable it can be achieved that the average squared loading is 1 as the result of standardization. As a consequence, there…

Accurate person identification is central to all security, police, and judicial systems. A commonplace method to achieve this is to compare a photo-ID and the face of its purported owner. The critical aspect of this task is to spot cases in which these two instances of a face do not match. Studies of person identification show that these instances…
