A General Approach to Defining Latent Growth Components

We present a 3-step approach to defining latent growth components. In the first step, a measurement model with at least 2 indicators for each time point is formulated to identify measurement error variances and obtain latent variables that are purged from measurement error. In the second step, we use contrast matrices to define the latent growth components representing the constructs of substantive interest. The corresponding matrix of structural coefficients is then computed by inverting the contrast matrix. In the third and last step, the first 2 steps are integrated into a structural equation model. The particular strength of this approach is that it permits construction of latent growth components in such a way that they represent interesting contrasts from a substantive point of view. This is illustrated using data of cancer patients obtained from 3 fatigue scales of the multidimensional fatigue inventory measured at 4 time points.

Quintilian: Wisdom and Warning

The implementation of online texts, videos, homework, and tests has changed the process of instruction in introductory college mathematics courses. With this change, more of the students’ learning takes place outside of the traditional college classroom and in places such as tutoring centers and dorm rooms. A combination of chi-square tests—for independence with unordered categorical data—and Mann-Whitney two-sample rank-sum tests—for continuous data and ordered categorical data—were used to analyze student outcomes generated from College Algebra and Applied Calculus courses with class sizes ranging from 37 to 129, with common syllabi, homework, quizzes, and tests. These tests showed that medium classes (30–55 students) had little to no benefit over large classes (110–130 students) in student learning and student achievement, with large classes having small to medium positive-effect sizes over medium classes in the area of student satisfaction. The only area in which the small classes had a small positive effect was in the area of student engagement.     

Creative Teaching

Decoding disciplinary expertise for novices is increasingly part of the undergraduate curriculum. But how might area studies and other interdisciplinary programs, which require integration of courses from multiple disciplines, decode expertise in a similar fashion? Additionally, as a part of decoding area studies and interdisciplines, how might a sequential experience of library-based research practice support that curriculum? Finally, how might a program introduce students to fellowships and career opportunities in the field early in their studies? Area studies and interdisciplinary departments face particular challenges in this regard because of multiple entry points into the major and the lack of a consistent pattern of student movement through the major (due to students studying abroad or because of the array of different disciplinary courses comprising individual programs of study). A tested course designed to address these issues, and adaptable for other area studies or interdisciplinary programs, is part of the required curriculum for Asian Studies at St. Olaf College in Northfield, MN.     

The research and evaluation of serious games: Toward a comprehensive methodology

The authors present the methodological background to and underlying research design of an ongoing research project on the scientific evaluation of serious games and/or computer‐based simulation games (SGs) for advanced learning. The main research questions are: (1) what are the requirements and design principles for a comprehensive social scientific methodology for the evaluation of SGs?; (2) to what extent do SGs contribute to advanced learning?; (3) what factors contribute to or determine this learning?; and (4) to what extent and under what conditions can SG‐based learning be transferred to the real world? In the Netherlands between 2005 and 2012, several hundred SG sessions with 12 SGs were evaluated systematically, uniformly and quantitatively to create a dataset, which comprises data on 2488 respondents in higher education or work organizations. The authors present the research model, the quasi‐experimental design and the evaluation instruments. This focus in this paper is on the methodology and dataset, which form a sound foundation for forthcoming publications on the empirical results.     

Authentically assessing graduate teaching: outside and beyond neo-liberal constructs

In this paper, we challenge the current focus on ‘best practice’, graduate teacher tests, and student test scores as the panacea for ensuring teaching quality and argue for ways of thinking about evidence of quality beginning teaching outside and beyond the current neoliberal accountability discourses circulating in Australia and other countries. We suggest that teacher educators need to reinsert themselves as key players in the debates around quality beginning teaching, rather than being viewed as a source of the problem. To enable teacher educators to assume accountability for quality beginning teachers, we propose the framework of a capstone teacher performance assessment—a structured portfolio called the Authentic Teacher Assessment (ATA)—and examine examples of these assessments through the lens of critical discourse analysis. As a measure of ‘readiness to teach’, the ATA is compared with supervising teachers’ assessments of preservice teachers. We argue that structured portfolios that include artefacts derived from preservice teachers’ practice in classrooms along with graduate teacher self assessments provide a stronger accountability measure of effective beginning teaching and demonstrably address the current anxiety regarding ‘evidence’. We suggest that such an approach should be reliable enough to be ‘read’ by external assessors (and moderated across other teacher education institutions). Rigorous research on a national basis is called for in order to develop and implement a structured portfolio as rich evidence of graduates’ quality and readiness to teach.     

Old Advice for New Researchers

In this paper, I offer advice to new researchers on how to conduct a successful research project in educational psychology. I break the research task into three parts: creating a research question, creating a research methodology, and creating a dissemination plan. The criteria for creating a research question include personal interest, educational relevance, theoretical grounding, and empirical testability. The criteria for creating a research methodology include that the method provides relevant evidence, is feasible, and is as simple as possible. The criteria for creating a dissemination plan include basing your argument on research evidence, presenting your argument in coherent style that links your main findings with theoretical and practical implications, and seeking the best possible peer-reviewed publication venue.     

Evaluating a web based intelligent tutoring system for mathematics at German lower secondary schools

The present study researches the implementation of a web based intelligent tutoring system for mathematics at lower secondary schools. In recent years, there is growing concern about the worrying situation at German lower secondary schools. Data from large scale educational assessments in the county of North Rhine-Westphalia (NRW) show that children at lower secondary schools have an embarrassing paucity of basic mathematical skills (Leutner et al., Lernstandserhebungen 9. Klasse 2004 in NRW: Erster Kurzbericht zur wissenschaftlichen Begleitung, 2004). In order to improve these basic mathematical skills in lower secondary school children, several schools implemented the web based intelligent tutoring system eFit. The aim of the present research was to investigate whether eFit constitutes an effective intervention of this target group. The results show that compared to a non-treatment control group, children in the eFit group significantly improved their arithmetic performance over a period of 9 months. As will be discussed, the findings have to be treated with cautions because eFit was specifically designed to alleviate mathematical difficulties and therefore “trained for the test” whereas traditional mathematics instruction followed the regular curriculum. The implications of this will be considered in the light of existing theory and research.

Can the linguistic interdependence theory support a bilingual-bicultural model of literacy education for deaf students?

Drawing on Cummins' (1989) linguistic interdependence model, proponents of bilingual-bicultural models of literacy education for deaf students claim that, if ASL is well established as the L1, then literacy in English (L2) can be achieved by means of reading and writing without exposure to English through either speech or English-based sign. In our opinion, this claim is based on a false analogy: the situation of the deaf learner of English literacy does not match the conditions assumed by the linguistic interdependence model. We draw on the work of Vygotsky and Halliday to develop a conceptualization of the processes involved in becoming literate, examining the particular and unique challenges that deaf students face as they strive to become members of the linguistic community of users of written English. We argue that becoming literate involves mastering three modes of lanuage use: 'social speech,' 'inner speech,' and written text. In some respects the educational context for deaf students is analogous to that of other bilingual learners; in some crucial aspects, it is very different.
