This paper reports the validation scores of the Student Tool for Technology Literacy (ST2L), a performance-based assessment based on the National Educational Technology Standards for Students (NETS*S) used to measure middle grade students Information and Communication Technology (ICT) Literacy. Middle grade students (N 1⁄4 5884) from school districts across the state of Florida were recruited f...

Despite the fact that both the Efficient Market Hypothesis and Random Walk Theory postulate that it is impossible to predict future stock prices based on currently available information, recent advances in empirical research have been proving the opposite by achieving what seems to be better than random prediction performance. We discuss some of the (dis)advantages of the most widely used perfo...

The purpose of this study is to contribute to efforts to improve methods for gathering and analyzing data from classroom observations in early literacy. The methodological approach addresses current problems of reliability and validity of classroom observations by taking into account differences in teachers’ uses of instructional actions (e.g., modeling) in specific skill areas (e.g., fluency, ...

Web surveys have become a very important way of empirical research. The rise of social media provides a new platform for web surveys. Investigators can collect data based on different social media platforms to get more respondents of higher external validity at a lower cost. However, there is no domestic expert and scholar to conduct related researches on web surveys based on social media. This...

Purpose This research examines current and prospective consumer perceptions, purchase intent and parent brand evaluation due to green brand – line and category extensions by marketers of established (non-green) brands for products with high versus low perceived environmental impact. Design/Methodology/Approach Response to online surveys by 602 pet-owners at social networking websites. The quasi...

a r t i c l e i n f o The valuable relationships hypothesis posits that people are inclined to reconcile with their valuable-relationship partners. Focusing on a particular type of credible conciliatory signal (i.e., costly apology), the present study tested this hypothesis from the perpetrator's perspective. In studies 1 and 2, after imagining that they had committed an interpersonal transgres...

The generalizability of empirical findings to new environments, settings or populations, often called “external validity,” is essential in most scientific explorations. This paper treats a particular problem of generalizability, called “transportability”, defined as a license to transfer causal effects learned in experimental studies to a new population, in which only observational studies can ...

Rising standards for accurately inferring the impact of development projects has not been matched by equivalently rigorous procedures for guiding decisions about whether and how similar results might be expected elsewhere. These ‘external validity’ concerns are especially pressing for ‘complex’ development interventions, in which the explicit purpose is often to adapt projects to local contextu...

Many economic experiments are run in the laboratory with students as participants. In this paper we use a newspaper experiment to learn more about external validity of lab research. Our workhorse is the Yes-No game. Unlike in ultimatum games responders of the YesNo games do not know the proposal when deciding between whether to accept it or not. We use two different amounts that can be shared (...
