Anatomical sciences: A foundation for a solid learning experience in dental technology and dental prosthetics

Basic science courses are extremely important as a foundation for scaffolding knowledge and then applying it in future courses, clinical situations as well as in a professional career. Anatomical sciences, which include tooth morphology, oral histology, oral embryology, and head and neck anatomy form a core part of the preclinical courses in dental technology programs. In this article, the importance and relevance of anatomical sciences to dental personnel with no direct contact with patients (dental technicians) and limited discipline related contact with patients (dental prosthetists) is highlighted. Some light is shed on the role of anatomical sciences in the pedagogical framework and its significance in the educational process and interprofessional learning of dental technicians and prosthetists using oral biology as an example in the dental curriculum. To conclude, anatomical sciences allow dental technicians and prosthetists to a gain a better insight of how tissues function, leading to a better understanding of diagnosis, comprehensive treatment planning and referrals if needed. Patient communication and satisfaction also increases as a result of this deep understanding of oral tissues. Anatomical sciences bridge the gap between basic science, preclinical, and clinical courses, which leads to a holistic approach in patient management. Finally, treatment outcomes are positively affected due to the appreciation of the macro and micro structure of oral tissues.

Students’ perspectives of early assessment tasks in their first-year at university

Assessment plays an important role in first-year students’ transition to university, influencing how they learn. Poorly designed assessment can be demotivating and may even cause students to withdraw from university. An early low-stakes assessment task is recommended in first year, to provide information to students and staff on student progress, provide students with a positive experience and help them prepare for future assessments. This paper reports on first-year students’ experiences of two different early assessment tasks for two disciplines, one using an online quiz and the other a ‘research challenge’ that served as a precursor to writing an essay. The paper also presents lecturers’ reflections on what they learned, what they would change and the implications for others planning early assessment tasks for first years. Finally, ideas for future research are provided.     

Spontaneous recovery after extinction of a conditioned taste aversion

Four experiments examined whether or not spontaneous recovery could occur after extinction in the conditioned taste-aversion paradigm. After three extinction trials, spontaneous recovery was obtained over an 18-day retention interval (Experiments 1, 2, and 3). The effect was not due to changes in the unconditioned preference for saccharin over the retention interval (Experiment 2) or to an increase in a nonextinguished aversion over time, as indicated by tests with both the original, nonextinguished aversion (Experiment 1) and with a weaker one (Experiment 3). Spontaneous recovery was not obtained when extinction was overtrained (eight trials) and a 49-day retention interval was used (Experiment 4). However, saccharin intake at asymptote reached the level of baseline water intake, and not the highly preferred level shown by never-conditioned controls. Results of all four experiments suggest that extinction does not return an averted taste to the status of an unconditioned one.     

The influence of field experiences on stages of concern and attitudes of preservice teachers toward science and science teaching

The purpose of the study was to determine whether the field experience component of an undergraduate science methods course influenced teachers' concerns and attitudes toward science and science teaching. Age, grade-point average, openmindedness, and school assignment were examined as factors which might explain some of the variance in the dependent measures. A one-group pretest-posttest design was used. Students were administered the Teacher Concerns Questionnaire, the Science Teaching Attitude Scales, and the Rokeach Dogmatism Scale approximately eight weeks after the pretest. Results indicated that field experiences did not significantly change student concerns about teaching science but significantly improved student attitudes toward science and science teaching. Students differing in age, grade-point average, and openmindedness did not difer significantly in changes in concerns and changes in attitude toward science and science teaching. Students assigned to different schools differed significantly in changes in attitude toward science.     

School factors underlying demand for private supplementary tutoring in English: urban and rural variations in Bangladesh

Private supplementary tutoring has long existed in Bangladesh, as elsewhere in the world, but in recent decades has become much more visible. Much tutoring “shadows” or reproduces formal schooling as fee-based academic teaching outside school hours. This paper focuses on school factors that shape demand for private supplementary tutoring in English at the secondary level, drawing on data gained from both quantitative and qualitative methods. The paper is especially concerned with urban and rural variations, noting that rates of tutoring are greater in urban areas but that many factors converge to create similarities. Private tutoring in English is highly demanded because English is a compulsory course; and in addition to being a subject in its own right, it assists in the learning of other subjects. While private tutoring may support the academic learning of some pupils, it also has problematic dimensions. As such, the spread of tutoring across urban and rural areas is not necessarily to be welcomed.     

Collaborative action research for middle grades improvement

Technology’s rapid evolution applies constant pressure to educational organizations, suggesting a need to continually re-envision schools for the digital age. Yet educators often struggle to understand the growing chasm between students’ out-of-school and in-school technology lives. This gap is particularly noticeable during the middle grades years, when home technology use increases dramatically. The purpose of this research was to examine the experiences of teachers and students engaged in collaborative action research for middle school improvement in technology-rich settings. We begin by outlining our theoretical framework, emphasizing Fletcher’s Ladder of Student Involvement. We then describe our case-study design and methods. Findings are organized by action research components and a discussion of key themes follows. Finally, we consider the implications of this study for action research as a means of student involvement and teacher learning.     

Using generalizability analysis to estimate parameters for anatomy assessments: A multi‐institutional study

With integrated curricula and multidisciplinary assessments becoming more prevalent in medical education, there is a continued need for educational research to explore the advantages, consequences, and challenges of integration practices. This retrospective analysis investigated the number of items needed to reliably assess anatomical knowledge in the context of gross anatomy and histology. A generalizability analysis was conducted on gross anatomy and histology written and practical examination items that were administered in a discipline‐based format at Indiana University School of Medicine and in an integrated fashion at the University of Alabama School of Medicine and Rush University Medical College. Examination items were analyzed using a partially nested design in which items were nested within occasions (i:o) and crossed with students (s). A reliability standard of 0.80 was used to determine the minimum number of items needed across examinations (occasions) to make reliable and informed decisions about students' competence in anatomical knowledge. Decision study plots are presented to demonstrate how the number of items per examination influences the reliability of each administered assessment. Using the example of a curriculum that assesses gross anatomy knowledge over five summative written and practical examinations, the results of the decision study estimated that 30 and 25 items would be needed on each written and practical examination to reach a reliability of 0.80, respectively. This study is particularly relevant to educators who may question whether the amount of anatomy content assessed in multidisciplinary evaluations is sufficient for making judgments about the anatomical aptitude of students.

A comparison between the time-management skills and academic performance of mature and traditional-entry university students

Time-management skills are acknowledged to be important but there has been little actual research on this topic with students. In this study we examined the scores obtained from 293 first-year students of psychology on a British version of an American time-management scale. The students were divided into three age groups: traditional-entry students - aged less than 21 years (N = 172); borderline mature students - aged 21–25 years (N = 50) and older mature students - aged more than 25 years (N = 71). Our analyses indicated (i) that women students in general reported significantly greater time-management skills than did men students, and (ii) that our older mature students reported significantly better time-management skills than did the other two groups. Academic performance, however, was only modestly predicted by age and scores on one component of the time-management scale.     

School Adjustment in Sixth Graders: Parenting Transitions, Family Climate, and Peer Norm Effects

This study examined whether sixth graders' (mean age = 11.86 years) adjustment to the school context (assessed by grades, achievement scores, and disruptive behavior) was affected by factors from both the family context (represented by students' reports of the number of parenting transitions experienced as well as current levels of supervision, acceptance, autonomy granting, and conflict in the family) and the peer context (represented by students' perceptions of peer norms supporting academic excellence). School adjustment was related to the number of parenting transitions experienced, family climate, and peer norms as well as to higher-order relations involving family climate and peer norms such that ( a ) high grade point averages occurred at only moderate levels of family supervision, ( b ) achievement scores were positively related to supervision at only low levels of family autonomy granting, and ( c ) grade point average was positively related to peer norms at only high levels of family acceptance.     

Self-Operated Verbal Instructions for People with Intellectual and Visual Disabilities: Using instruction clusters after task acquisition

Three adults with intellectual and visual disabilities were taught vocationally relevant tasks through the use of a self-operated verbal instruction system. During training, the system presented one verbal instruction per task step, individually. After training, the system presented instructions arranged in clusters/groups of two. Data showed that during training all participants achieved percentages of correct task performance exceeding 90. The subsequent use of instruction clusters was effective in maintaining high levels of correct performance for each adult, whereas a deterioration of performance occurred when instructions were not available. Implications of the findings are discussed.
