Practical independent research projects in science: a synthesis and evaluation of the evidence of impact on high school students

Practical independent research projects (IRPs) are a feature of school science in a number of countries. To assess the impact of IRPs on students, a systematic review of the literature was undertaken. Thirty-nine papers met the review inclusion criteria, reporting on work from twelve countries. The review indicates that IRPs are often associated with wider initiatives such as authentic science, problem-based learning, and project-based learning. There is considerable variability in the nature of IRP work in relation to focus, models of provision, assessment, the involvement of external partners such as universities and employers, and funding, and this diversity affects judgements on the quality of the evidence base on impact. The majority of the research reviewed explored areas such as conceptual understanding, motivation to study science once it is no longer compulsory and attitudes to science, and the development of practical skills. Benefits were identified in relation to the learning of science ideas, affective responses to science, views of pursuing careers involving science, and development of a range of skills. Studies focusing on traditionally under-represented groups indicated that such students felt more positive about science as a result of undertaking IRPs. The review findings indicate that further work is needed to enhance the quality of the available evidence, to consider the ways in which IRPs can be validly assessed, to explore more fully the potential benefits for traditionally under-represented groups, and to explore more fully the potential longer-term benefits of participation in IRPs at high school level.     

Marketing undergraduates' attitudes towards query-based instructional machines as a possible learning medium

Six hundred and seventy-one undergraduates completed a questionnaire concerning their reactions to the idea that parts of their degree programmes might be delivered via Query Based Instructional Machines. The latter are commonplace in museums and other cultural attractions. They are menu-driven and operate on the touch-screen principle, thus allowing the user to browse through whichever aspects of a subject the person finds most interesting. Cognitive, affective and conative responses were measured and related to students' personal characteristics, degree programme, year of study, level of academic attainment, psychological involvement with a course, and innate tendencies vis-à-vis need for cognition, curiosity, and change leadership. The sample comprised students on three categories of degree programme: marketing, computing, or humanities. An analysis of covariance (ANCOVA) was completed using aggregated responses as dependent variables, degree type as the fixed factor (grouping variable), and personal characteristics and inclinations as covariates. There were a number of significant differences between the responses of the marketing students and students in the other groups.     

Biological constraints on instrumental and classical conditioning: Retrospect and prospect

The adequacy of traditional approaches to the study of animal learning to account fully for learning phenomena has been seriously questioned during the past decade. Critics of traditional analyses advocated a biological orientation to the interpretation of associative processes and introduced a variety of concepts intended to provide a new framework for the study of animal learning. This promise of a reorientation of the field has not been realized. The concepts of biological constraints, adaptive specializations, and situation specificity of learning have had a less profound influence on the general process approach to instrumental and classical conditioning than anticipated. The present paper makes explicit the conceptual bases of the original biological approaches to learning, identifies reasons why they failed to change fundamentally the study of instrumental and classical conditioning, and proposes an alternative approach to the use of ecological and evolutionary principles in studies of conditioning. We suggest a renewed comparative approach to the study of learning phenomena that avoids many of the difficulties inherent in earlier formulations by providing (1) a strategy for the discovery of adaptive specializations in learning, (2) an ecological framework for the discussion of these adaptive specializations, and (3) a renewed emphasis on the study of species differences in learning.     

‘I have a love–hate relationship with ATLAS.ti’™: integrating qualitative data analysis software into a graduate research methods course

While research on teaching qualitative methods in education has increased, few studies explore teaching qualitative data analysis software within graduate-level methods courses. During 2013, we required students in several such courses to use ATLAS.ti? as a project management tool for their assignments. By supporting students’ early experiences with ATLAS.ti?, we anticipated that they might continue using the tool in their future research work. Using a case study and reflective practice approach, we reviewed course materials, including student and instructor reflections, to understand what happened when data analysis software was integrated into an advanced methods course. We identified five major themes: (1) a needed push out of their comfort zones; (2) various forms of support working together; (3) keys to motivation; (4) a new generation educating the current one and (5) use of the software beyond coursework. Implications for practice include ensuring adequate access and support for learning the software, balancing methodological and technical instruction, and creating meaningful student assignments and feedback opportunities.     

Toxicosis-based aversions to visual cues in rats: A test of the Testa and Ternes hypothesis

Testa and Ternes have proposed that the degree of spatial contiguity between a cue and a food object is an important determinant of the associability of that cue with toxicosis. We found, in accord with the Testa and Ternes hypothesis, that rats showed more profound illness-based aversions to the visual properties of food objects than to the visual properties of food bins or feeding chambers. This result has implications for the design of experiments undertaken to determine the relative associability of cues in different sensory modalities with toxicosis.     

Processing procedural documents: A cognitive model for following written directions

This paper reviews empirical literature on how people use documents to perform tasks. We examine studies that have been published under the topics of: following written directions, reading maps, following instructions, using job performance aids, and processing procedural texts. Documents that contain a procedure, such as a set of directions, require transformation of information. Such transformation frequently requires converting a procedure represented verbally in a text into a procedure represented behaviorally in a performance. To accomplish this transformation, we propose that students must: (a) form a conceptual model of the performance; (b) encode procedures from the document; (c) engage in self-testing; and (d) conduct self-corrections to repair mistakes. We further propose that these operations are performed most efficiently with distinctive information resources. An overview of the task is likely to be most effective in facilitating conceptual model formation. Procedural information that emphasizes temporal characteristics of the performance will facilitate the encoding of procedures. A representation of the outcome (usually graphic) improves self-testing, and the comparison of the outcome with progress in the workspace leads to most effective self-correction. This process-resource interaction minimizes the number and complexity of transformations required to process procedural documents.     

The basis of feeling-of-knowing judgments in patients with schizophrenia

We examined the basis of feeling-of-knowing judgments (FOK) in patients with schizophrenia. Such patients typically have impaired memory and awareness, but not metamemory-accuracy deficits. The magnitude of FOKs are lower for patients with schizophrenia than for healthy participants, but judgments equally predict memory performance. In healthy participants, FOK is based on accessible information, including retrieval of partial-target (e.g., retrieving the first letter) and contextual information (e.g., related facts). In Experiment 1, we examined if accessible information predicts FOKs for episodic memory in patients with schizophrenia. Patients and healthy controls learned names paired with drawings of imaginary animals. The results showed that patients’ FOK increased with the retrieval of partial-target and contextual information. In Experiment 2, using semantic-memory general-information questions, accessible partial-target information predicted FOKs in patients with schizophrenia. The accessibility model of FOK applies to patients with schizophrenia, and it is important to determine what occurs in other memory-impaired populations.     

Homeschool background,time use and academic performance at a private religious college

We study the effects of homeschool background and time use on academic performance among students at Patrick Henry College, a private religious institution with a 63-credit core classical liberal arts curriculum. Using ordinary least squares regression analysis, we examine four research questions: (1) Does time use influence academic performance? (2) Do homeschooled students perform differently than traditionally schooled students? (3) Does parental education moderate the impact of homeschooling on academic performance? (4) Does homeschooling moderate the impact of ACT scores on academic performance?     

An Australian study of possible selves perceived by undergraduate engineering students

In this study, we worked with second-year engineering students at an Australian university to examine previously identified threshold concepts within the theoretical framework of Possible Selves. Using workshops as the context for intensive work with students, students were encouraged to consider their future lives and work, including their engineering fears, expectations, and aspirations. The findings revealed many students to have a poor understanding of the realities of engineering work. Moreover, perceived gaps between self-efficacy and the requirements of engineering work appeared to be motivating if students deemed it possible to reduce the gap, but demotivating if they identified a characteristic over which there was perceived to be no control. The study suggests that these engineering students needed more opportunities to explore both the roles of engineers and their own possible selves. Overall, the findings indicate that higher education students may need encouragement and support to explore potential future roles, and they strengthen calls for further research in this area.
