Researchers sometimes conduct a study and find that the predicted relation between variables did not exist or that the intervention did not have a positive impact on student outcomes; these are referred to as null findings because they fail to disconfirm the null hypothesis. Rather than consider such studies as failures and disregard the null…

This chapter examines the impact of declining student response rates on surveys administered at small- and medium-sized institutions. The potential for nonresponse bias and its effects are addressed.

This paper provides a critical review of Processing Instruction (PI). This type of instructional option was specifically designed to help second/foreign language (L2) learners grasp meaning manifested in the use of particular grammatical forms in a target language effectively through the provision of input. In this way, PI attempts to help…

Value-added estimates of teacher or school quality are increasingly used for both high- and low-stakes accountability purposes, making understanding of their limitations critical. A review of the recent value-added literature suggests three concerns with the state of the research. First, the issues receiving the most research attention have not…

Prompted by discovering a paper written in 1980 which described a process of 'ethnography by proxy', I revisit this concept in the light of two research projects: a workplace study of an electronics company conducted in the early 1990s and a later home-based study of young children's encounters with toys and technology. The paper defines…

In this paper, we investigate two purported problems with Bayesian Knowledge Tracing (BKT), a popular statistical model of student learning: "identifiability" and "semantic model degeneracy." In 2007, Beck and Chang stated that BKT is susceptible to an "identifiability problem"--various models with different…

Formative experiments offer researchers the opportunity to partner with classroom teachers to design interventions to address problems that occur in the classroom. The teacher identifies goals for the students, and then the teacher-researcher team designs interventions to meet these goals. During the study, the team modifies the intervention as…

This report considers the use of a focus group as a data collection tool in early childhood research. The report outlines one researcher's experience, analyzing the difficulties of gaining meaningful data during focused group discussions, considering in some depth the impacts of careful management on the validity of the findings, providing…

In this case, I share my process of analyzing data in a multiple case study. The study looked at the interconnections between contexts, leadership, and educational equity to better understand how superintendents lead systems that offer equitable educational experiences for all students. Data included 16 one-on-one interviews with four…

Age-period-cohort (APC) models are designed to estimate the independent effects of age, time periods, and cohort membership. However, APC models suffer from an identification problem: There are no unique estimates of the independent effects that fit the data best because of the exact linear dependency among age, period, and cohort. Among methods…

Background: Stratified medicine seeks to identify patients most likely to respond to treatment. Individual participant data (IPD) network meta-analysis (NMA) models have greater power than individual trials to identify treatment-covariate interactions (TCIs). Treatment-covariate interactions contain "within" and "across" trial…

Support services for students with disabilities is now a distinct field of practice in higher education, with a significant increase in the number of students receiving services, programs to serve them, and professionals who oversee the programs. The field has professional and program standards, a code of ethics, and a disability service specific…

This methodological paper discusses how photographs can be used in multi-layered data projects with children and families. We present photographs as a versatile low-fi digital artifact that can be used under a variety of research circumstances and critically discuss this particular visual tool in the context of the growing body of visual and…

Contrary to the charge that advocacy-oriented research cannot meet social science research standards because it is inherently biased, the authors of this article argue that collaborative, community-engaged scholarship (CCES) must meet high standards of rigor if it is to be useful to support equity-oriented, social justice agendas. In fact, they…

It seems that plagiarism has not been seen as misconduct in higher education in some developing countries including in Indonesia which might be affected by cultural, economic, and technological issues. The research aimed at exploring the perceptions of Indonesian student teachers towards plagiarism in four higher education institutions. The…
