Factors influencing success in introductory college chemistry

Previous research has found a wide range of predictors of student performance in introductory college chemistry. These predictors are associated with both the students' backgrounds and their high school learning experiences. The purpose of this research study was to examine the link between high school chemistry pedagogical experiences and performance in introductory college chemistry while accounting for individual educational and demographic differences. The researchers surveyed 1531 students enrolled in first‐semester introductory college chemistry courses for science and engineering majors at 12 different U.S. colleges and universities. Using multiple regression analysis, the researchers uncovered several interesting high school pedagogical experiences that appeared to be linked with varying levels of performance in college chemistry. Most notably, the researchers found that repeating chemistry labs for understanding was associated with higher student grades, whereas overemphasis on lab procedure in high school chemistry was associated with lower grades in college. These results suggest that high school teachers' pedagogical choices may have a link to future student performance. © 2005 Wiley Periodicals, Inc. J Res Sci Teach 42: 987–1012, 2005     

No comparison: Distance education finds a new use for ‘No significant difference’

Media comparison studies have long been criticized as an inappropriate research design for measuring the effectiveness of instructional technology. However, a resurgence in their use has recently been noted in distance education for program evaluation purposes. An analysis of the research design will detail why such a methodology is an inappropriate approach to such an investigation. Increased access to such programming does not seem to serve as a satisfactory benefit for the implementation of distance education efforts. Stakeholders desire to prove that participants in distance-delivered courses receive the same quality of instruction off-campus as those involved in the traditional classroom setting. However, the desire to prove that the quality of such distributed offerings is equal to the quality of on-campus programming often results in comparisons of achievement between the two groups of student participants. Statistically, such a research design almost guarantees that the desired outcome will be attained—that indeed distance learners perform as well as campus-based students.     

The reflective institution: Assuring and enhancing the quality of teaching and learning

Three definitions of ``quality' have entered the qualityassurance (QA) debate: quality as value for money, quality as fitfor the purpose of the institution, quality as transforming. The firstis pivotal for retrospective QA, which sees QA in terms ofaccountability, and conforming to externally imposed standards. The lasttwo are pivotal for prospective QA, which sees QA asmaintaining and enhancing the quality of teaching and learning in theinstitution. In this paper, the reflective practitioner is taken as themodel for prospective QA. Three stages are involved in institutionalreflective practice: articulating an espoused theory of teaching, thequality model (QM); continually improving on current practicethrough quality enhancement (QE), in which staff development should playan important role; and making quality feasible (QF), by removingimpediments to good teaching, which often arise through distortedpriorities in institutional policy and procedures. These three stages,QM, QE, and QF, are essential ingredients in prospective QA.     

School self‐evaluation and the role of a critical friend

School self‐evaluation is receiving increasing attention in England, partly as a result of changes in the Ofsted inspection framework giving greater prominence to what schools can do to speak for themselves. The relationship between internal self‐evaluation and external inspection was a theme in a high profile policy speech made by the Schools Standards Minister, David Miliband, at the North of England Conference in January 2004. As part of a ‘new relationship with schools’ heralded in the speech, Miliband articulated critical friendship in terms of a ‘school improvement partner’. This article draws upon a number of research projects to critique these proposals, especially in respect of the role of a critical friend in school self‐evaluation. Issues discussed include different models of self and external evaluation, the importance of context, and the various ways in which a critical friend can support school self‐evaluation.     

Adolescents and Cyber Bullying: The Precaution Adoption Process Model

A survey of adolescents (N?=?1,488) documented Facebook use and experience with cyber bullying. The study found that 84 % of adolescents (middle school through college undergraduates) use Facebook, and that most users log on daily. While 30 % of the sample reported being cyber bullied, only 12.5 % quit using the site, and only 18 % told a parent or school official about the abuse. Up to 75 % of middle school Facebook users have experienced cyber bullying. The current study was the first to apply the Precaution Adoption Process Model (PAPM) to cyber bullying or to test the model with children and adolescents. Results suggest that most adolescents are aware of cyber bullying and acknowledge it as a problem in their school. About half of the adolescents did not progress beyond Stage 2 of the PAPM (aware of the problem, but haven’t really thought about it). Adolescents also exhibited optimistic bias, believing they were less likely than peers to become cyber bullied. Implications for prevention education are discussed.     

Foraging on the radial-arm maze: Effects of altering the reward at a target location

Thirsty rats were trained to collect small water rewards from the end of each arm of an eight-arm radial maze. During these training trials and subsequent testing trials, the subjects were allowed to choose a maximum of eight arms. “Preference” for a target maze location was studied by noting when, in the sequence of eight choices, the target was selected. During testing, when one maze location was consistently devoid of water, rats decreased their preference for this arm over trials (Experiment 1). Similarly, rats that learned a saccharin-lithium association demonstrated lower preferences for a maze location that consistently held the conditioned saccharin solution. This was true for animals that received saccharin-lithium conditioning on the maze (Experiment 3A) and for animals conditioned to saccharin in a separate context (Experiment 3B). An increase in preference for a target maze location consistently containing a sweet chocolate milk solution was observed in animals that were water- and food-deprived (Experiment 2). These studies demonstrate that animals will modify their responses toward (preferences for) maze locations that predictably contain an altered reward.     

Overcoming resistance to formal instructional development processes

The instructional development (id) process sometimes is perceived as being too time-intensive and as delaying instructional materials development. Course writers holding these perceptions may resist following a formalid process or give only cursory attention to early stages in the process. Such a situation can create conflict between course writers and instructional designers responsible for implementing a particularid model. This article describes a way instructional designers can overcome some of the resistance to following theid process.     

Treatment of parents who abuse their children: A literature review and implications for professionals

This article contains a review of the current treatment approaches to child abuse in terms of the following models: psychopathological, sociological, social-situational, family systems and social learning. The psychopathological model of child abuse emphasizes direct services. The services provided may consist of individual, group and lay treatment, volunteer companions, and self-help groups. The sociological model's approach to intervention emphasizes the need for wide-ranging changes in social values and structures. The socio-situational model's approach to treatment is based upon the assumption that the cause of child abuse lies not in the individual, but in the social situation, which may, in turn, be maintaining abusive patterns of behavior. The family systems approach to treatment resembles that of the socio-situational model in that it too emphasizes changing the family's pattern of interaction and behaviors. Finally, the social learning approach to treatment involves the identification of behavioral goals, specific techniques for achieving these goals, and the use of social reinforcers to facilitate this process. Data indicate that parents who abuse their children face multiple social and psychological difficulties. It has been suggested that the reason why treatment programs have not prodoced significant results in treating parents who abuse their children is that they focus on only one of the factors that operate to produce child abuse, i.e., lack of child management skills, marital dissatisfaction, or vocation or interpersonal skills dissatisfaction. It is logical that a treatment approach to abuse must view the problem as multi-determined and services should be structured in such a manner. Thus, the comprehensive treatment program should consist of the following; (1) Child Management Program; (2) Marital Enrichment Program; (3) Vocational Skills Enrichment Program; (4) Interpersonal Skills Enrichment Program. Programs to accomplish the acquisition of requisite skills in each of the four areas of emphasis are chosen from the technology of applied behavioral analysis. Each of the four program components is reviewed along with the rationale for a comprehensive program delivered through a behavioral group work approach. The article concludes with a discussion of the implementation and evaluation of the program.
