Feedback and its effectiveness in a computer-aided personalized system of instruction course

In a computer-managed version of Keller's personalized system of instruction, students received frequent feedback from more advanced students within the course. Overall accuracy of student-provided feedback was 87%, and students complied with 61% of the feedback.     

Science and Scientism in Huston Smith's Why Religion Matters

Huston Smith is justifiably critical of scientism, the belief that science is the only reliable path to truth. He holds that scientism and the materialism that accompanies it have led to a widespread denial of the transcendence expressed in traditional religious world-views. He argues that evolutionary theory should be seen as a product of scientism rather than of scientific evidence, citing authors who claim that the fossil record does not support the idea of continuous descent with modification from earlier life forms. I suggest that he has underestimated the cumulative weight of evidence from many independent fields of science supporting neo-Darwinism. I argue that methodological (but not philosophical) naturalism is a basic assumption of scientific inquiry. Proponents of intelligent design assume a fixed plan or blueprint, which is compatible with Smith's understanding of God's timeless vision. By contrast, almost all biologists and many theologians today envisage a dynamic and open-ended process rather than the realization of the unchanging forms in a preexisting plan.     

Designer Theology: A Feminist Perspective

This is a critical look at the question of design from a feminist theological perspective. The author analyzes James Moore's 1995 Zygon article, "Cosmology and Theology: The Reemergence of Patriarchy." Then she looks at the relationship between science and religion from a feminist perspective, focusing on the kyriarchal nature of theology itself in light of the myriad power issues at hand. Finally, she suggests that, instead of pondering the notion of design, scientists and theologians might more fruitfully look for new ground for dialogue since feminist scholars are asking very different questions, not just answering questions differently.     

Searching for Salient Aspects of Resonant Interaction

This paper illustrates my quest for diversity, more specifically resonant interaction with products. Resonance occurs due to the perfect interplay between a person and a product. It evokes strong positive emotions, unique accompanying behaviour, heightened awareness and cognitive processing. In this paper, I first explain the importance of diversifying designs, especially now we are pursuing the next generation of digital products. I show that designing for resonance can be a way to achieve diversity. I clarify the concept of resonance and resonant interaction. Subsequently, I explain the importance of research through design to study this phenomenon, i.e., by designing in a way that results in experiential prototypes, and subsequently testing these prototypes, scientific knowledge can be generated. Through these prototypes, I study the relationship between the individual user with his concerns, values, personality, skills, senses and effectivities on the one hand, and the interaction and product characteristics on the other hand. The paper concludes with two studies illustrating the way of working and the kind of answers I am obtaining with respect to resonant interaction. It appears that one can design for personality and prolong positive emotions even after the interaction has stopped, which strengthens the case for searching for salient aspects of resonant interaction.     

结构方程模式的发展与应用

Error self-correction and spelling: improving the spelling accuracy of secondary students with disabilities in written expression

In order to improve the spelling performance of high school students with deficits in written expression, an error self-correction procedure was implemented. The participants were two tenth-grade students and one twelfth-grade student in a program for individuals with learning disabilities. Using an alternating treatments design, the effect of error self-correction was compared with a more traditional method of spelling practice. The intervention and follow-up phases were implemented over a 6-week period with maintenance checks conducted 4 and 8 weeks after the termination of instruction. Results indicated that the error self-correction procedure was superior to the traditional method of review during the intervention and follow-up phases, but some gains were lost during the maintenance phase.     

A Field-Tested Task Analysis for Creating Single-Subject Graphs Using Microsoft<Superscript>®</Superscript> Office Excel

Creating single-subject (SS) graphs is challenging for many researchers and practitioners because it is a complex task with many steps. Although several authors have introduced guidelines for creating SS graphs, many users continue to experience frustration. The purpose of this article is to minimize these frustrations by providing a field-tested task analysis for creating SS graphs using Microsoft^® Office Excel. Results from the field test are presented and the task analysis, which includes steps for creating a variety of SS graphs, is provided. The article includes various illustrations, a list of prerequisite skills, tips, and troubleshooting items.     

Look: No hands! Driving on the motorway

How drivers hold their steering wheels when they are driving has been studied in restricted ways for many years. Here I describe the advantages (and disadvantages) of a more naturalistic way of studying this phenomenon, and present the results from two studies that observed the hand positions of motorway drivers from an elevated vehicle. In the first study I tape-recorded the data as we passed traffic on the left, and in the second I used paper and pencil to record the data as traffic passed us on the right. In both studies few drivers kept to the recommended 10-2 (or more generous 9-3) position for holding the steering wheel, and approximately one-third of them were driving with one hand on the wheel. Very few of the drivers observed (some 2%) were using mobile phones, but two were driving with no hands on the wheel. The paper concludes with some discussion of the value of this methodology for obtaining realistic data.     

I WALK THE LINE: COMMENT ON MIKAEL LEIDENHAG ON THEISTIC EVOLUTION AND INTELLIGENT DESIGN

Is theistic evolution (TE) a philosophically tenable position? Leidenhag argues in his article “The Blurred Line between Theistic Evolution and Intelligent Design” that it is not, since it, Leidenhag claims, espouses a view of divine action that he labels “natural divine causation” (NDC), which makes God explanatory redundant. That is, in so far as TE does not invoke God as an additional cause alongside natural causes, it is untenable. Theistic evolutionists should therefore “reject NDC and affirm a more robust notion of divine agency.” However, this will, Leidenhag claims, have the effect that theistic evolutionists “will move their position significantly closer to Intelligent Design,” and so the line between TE and intelligent design is (or ought to be?) blurred. If successful, the criticism by Leidenhag would be bad news for theists who want to take science seriously and good news for those scientistic atheists according to whom there simply is no scientifically respectable way of combining theism and modern natural science in an overarching worldview. So, is TE stuck between a rock (of redundancy) and a hard place (of pseudo-science)? No, at least not due to the criticism offered by Leidenhag—but maybe religious naturalism is?     

Does work engagement increase person–job fit? The role of job crafting and job insecurity

Drawing on the expanded model of person–environment fit and job crafting theory, this study investigates the underlying processes of the relationship between work engagement and changes in person–job fit. A two-wave longitudinal study was conducted among 246 Chinese employees of a high technology company. As hypothesized, the results show that work engagement is positively related to changes in demands–abilities fit through changes in physical job crafting and positively related to changes in needs–supplies fit through changes in relational job crafting. As predicted, the positive relationship between work engagement and changes in relational job crafting (however, not changes in physical job crafting) is strengthened under conditions of high (vs. low) job insecurity. Our findings indicate that engaged employees craft their work in physical and relational ways, which creates a better person–job fit. The theoretical and practical implications are discussed.
