In today's age of information, the use of data is very powerful in making informed decisions. Data analytics is a field that is interested in identifying and interpreting trends and patterns within big data to make data-driven decisions. We focus on informal statistical inference and data modeling as a means of developing students' data analytics…

In our everyday life, we often need to anticipate the potential occurrence of events and their consequences. In this context, the way we represent contingencies can determine our ability to adapt to the environment. However, it is not clear how agents encode and organize available knowledge about the future to react to possible states of the…

This study investigated if prospective secondary science teachers enhance their argumentation skills and the interaction of the change in their argumentation skills with their conceptual knowledge during an argumentation-based guided inquiry course. 37 prospective secondary science teachers constituted the study sample. They were grouped according…

A survey (N = 524) examined how frequently college students engage in multitasking with social media, texting/instant messaging (IM), and music while studying/working and what motivates them to multitask with each medium. Four out of five participants multitasked with Facebook and texting/IM, and two out of three multitasked with music. Habit was…

Task repetition facilitates learners' performance, at least temporarily: Since learners are already familiar with the content of the task at the initial enactment, they are capable of focusing their attention on linguistic form during the following enactment. However, the analysis in previous studies treated various aspects of "form" as…

This study explores the construct validity of speaking tasks included in the TOEFL iBT (e.g., integrated and independent speaking tasks). Specifically, advanced natural language processing (NLP) tools, MANOVA difference statistics, and discriminant function analyses (DFA) are used to assess the degree to which and in what ways responses to these…

National cultural distance is considered to be a strong predictor of language learners' pragmatic competence. To test the actual effect of national cultural distance on pragmatic competence holistically and comprehension and production aspects of pragmatic competence discretely, the current study was conducted on two groups of undergraduate…

The way in which an event is packaged linguistically can be informative about the number of participants in the event and the nature of their participation. At times, however, a sentence is ambiguous, and pragmatic information weighs in to favor one interpretation over another. Whereas adults may readily know how to pick up on such cues to…

The constructs of complexity, accuracy and fluency (CAF) have been used extensively to investigate learner performance on second language tasks. However, a serious concern is that the variables used to measure these constructs are sometimes used conventionally without any empirical justification. It is crucial for researchers to understand how…

We examined how learning new second language (L2) words was affected by three "task type" conditions (reading only, reading with a dictionary, reading and word focused exercises), three "number of encounters" conditions and their combinations. Three groups of L2 learners (n = 185) were exposed to 30 target words (one group in…

Since the 1980s, task-based language teaching (TBLT) has enjoyed considerable interest from researchers of second language acquisition (SLA), resulting in a growing body of empirical evidence to support how and to what extent this approach can promote language learning. Although transferability and generalizability are critical assumptions for…

The present study tested the "interference hypothesis"-that learning and using more advanced representations and strategies requires the inhibition of prior, less advanced ones. Specifically, it examined the relation between inhibitory control and number line estimation performance. Experiment 1 compared the accuracy of adults' (N = 53)…

Studies comparing virtual and physical manipulative environments (VME and PME) in inquiry-based science learning have mostly focused on students' learning outcomes but not on the actual processes they engage in during the learning activities. In this paper, we examined experimentation strategies in an inquiry activity and their relation to…

Metacognition refers to students' knowledge and regulation of cognition, as well as their accuracy in predicting their academic performance. This study addressed two major questions: 1) how do metacognitive knowledge, regulation and accuracy differ across domains?, and 2) how do students' individual differences relate to their reported…

This is a pilot study of a proposed model for examining the main and interactionist effects of achievement goal orientations on moral function and the role of perceived ability as a potential moderator in sport morality levels through cluster analysis procedures. One hundred and three elite (103) athletes participating in Division I wrestling…
