College aspirations and expectations among new African-American mothers in late adolescence

It is a generally accepted finding in the sociological literature as well as in public discourse that adolescent mothers are less likely than their non-parenting counterparts to graduate high school and to attend college. For several decades, however, researchers have pointed out that the implied causal process from teen motherhood to academic failure has been largely unsupported by empirical research. In fact, scholars have recently argued that motherhood may actually serve as a positive turning point in the lives of young women. Using a sample of young African-American women, this study assesses the degree to which teen motherhood not only affects college aspirations but also expectations. Further, it tests the ability of these effects to explain the well-known educational attainment gap between teen mothers and their non-childbearing peers. Results indicate that, in general, young mothers’ college aspirations are similar to those of non-mothers, but that their generally high aspirations for academic success appear to be effectively countered by their decreased educational expectations.     

Computer‐Assisted Instruction and Conceptual Change

Abstract

In this study, the question was addressed which instructional conditions are required to teach students how they themselves can initiate and perform learning activities aimed at conceptual change. The CONTACT‐2 strategy (a computer‐assisted instructional strategy for promoting conceptual change in the domain of basic physical geography) served as starting point for the design of several training procedures aimed at enhancing self‐regulated learning. With the first experimental condition, strategic support was gradually withdrawn ('faded') within each instructional step, while, with the second experimental condition, the number of steps was reduced as the training continued. The original CONTACT‐2 condition served as control condition. Subjects were 65 fifth‐ and sixth‐graders (primary education). Dependent variables concerned students’ abilities to initiate and perform learning activities aimed at conceptual change, the quality of their conceptions, and their learning performance. Results suggested that ‘fading’ can be a fruitful instructional approach to foster self‐regulated learning aimed at conceptual change, provided that the ‘fading’ procedure is tuned to the students’ actual level of self‐regulated learning: external control should not be withdrawn until students are able (and prepared) to initiate and perform the learning activities being required. When these conditions are met, designing effective training procedures aimed at ‘learning for conceptual change’ seems possible.     

A dilemma‐centered analysis of Clinton's August 17th apologia: Implications for rhetorical theory and method

In his apologia following a day of grand jury testimony on August 17th, 1998 President Clinton faced a number of rhetorical dilemmas stemming from his illicit relationship with Monica Lewinsky and his subsequent, ill‐fated attempts at covering it up. This essay offers a dilemma‐centered analysis of Clinton's rhetorical situation and provides an assessment of the strategic appropriateness of the speech in light of a theory of the rhetorical event. In so doing it makes frequent reference to the extensive CRTNET commentary on the speech, this both for purposes of assisting in the assessment and for illuminating problems with rhetorical theory and method.     

How we should control time on task—or should we?

Typical experimental studies of learning aids will control in various ways for the time spent on the learning task. This paper reviews such methods and compares the possible confounding influences of indirect time effects in experiments with broad or restrictive time limits. Indirect time effects refer to changes in time spent on a text that are caused by learning aids. They are to be discerned from direct time effects that refer to the time the reading of the learning aids take. In particular, we give an overview of the adequacy of various time limits for answering different research questions. It is argued that experiments without time limits are potentially more likely to bring out performance effects. In the final part of this paper we give some illustrations of the different effects and methods, based on a series of six experiments into the influence of concrete analogies on learning. Those experiments show that indirect time effects are important and that performance results depend on the way one controls reading time.     

A selective analysis of empirical findings in networked learning research in higher education: Questing for coherence

In this paper, we have attempted two ambitious tasks. We have undertaken a wide-ranging survey of the Network learning (NL) literature, and tried to identify the emerging themes of this work. We have selected three of these themes, and in each case tried to identify the main theoretical perspectives in use, the main directions of the studies, and the key ideas being addressed and researched. We have also tried to indicate where the main research effort might be directed in order to help to ‘fill in the gaps’ and achieve some coherence for the theme. Our second major task has arisen from our assertion that the field of Networked Learning research is theoretically fragmented. We have argued that this situation arises because Networked Learning research is a new field, and is drawing upon a wide range of theoretical perspectives. However, unless we can achieve some synthesis of these perspectives we may find it difficult to establish a coherent research programme in the field. We argue that one way of developing some coherence is to make theory and praxis interact explicitly, in other words, to ‘converse’ with each other in our research. By this we mean, to use theory to interrogate praxis, and use praxis to modify and develop theory, thus moving towards perspectives that are changing theory, modifying and improving it. As part of this argument, we have briefly surveyed the current level of Theory–Praxis Conversation, either explicit, or implicit, in the thematic research we have described. It is clear that some outstanding work is being done to make theory work, and to modify it in the light of research into praxis. However, it is also the case that much current Networked Learning research does not interrogate the theory that it uses to contextualise it. We see Theory–Praxis Conversation as a way of thinking explicitly about how we might make the work of interrogating theory in our research more explicit and systematic. In this way, our ‘Quest for Coherence’ may, we hope, help Networked Learning research to climb up to the higher ground, and give us a wider ranging view of learning in networked environments.
