Model of affective learning for nonformal science education facilities

Objective setting and evaluation for learning in the affective domain are often neglected in educational programs, largely because affective learning is a poorly understood phenomenon. This is particularly problematic in nonformal science education facilities, which are uniquely suited to facilitate affective learning. To address this problem, a heuristic model of affective learning in nonformal educational facilities was developed. The model, referred to as the Meredith Model, displays a sequence of events occurring in the affective responses of learners in nonformal educational experiences and identifies factors which may influence individual events within this sequence. The model is proposed as a conceptual framework for gaining an increased understanding of affective learning and for making recommendations for practice of nonformal science education and for further research.

The impact of inquiry-based learning on the critical thinking dispositions of pre-service science teachers

ABSTRACT

In the study, the impact of inquiry-based learning on pre-service teachers’ critical thinking dispositions was investigated. The sample of the study comprised of 56 pre-service teachers in the science education teacher education programme at the public university in the north of Turkey. In the study, quasi-experimental design with an experimental and a control group were applied to find out the impact of inquiry-based learning on the critical thinking dispositions of the pre-service teachers in the teacher education programme. The results showed that the pre-service teachers in the experimental group did not show statistically significant greater progress in terms of critical thinking dispositions than those in the control group. Teacher educators who are responsible for pedagogical courses in the teacher education programme should consider that the inquiry-based learning could not be effective method to improve pre-service teachers’ critical thinking dispositions. The results are discussed in relation to potential impact on science teacher education and implications for future research.     

The impact of science content and professional learning communities on science teaching efficacy and standards‐based instruction

This study examines the impact of standards‐based professional development on teacher efficacy and instructional practice of elementary and middle school science teachers. Professional development activities were conducted over a period of 3 years and included content courses as well as teacher involvement in professional learning communities. Teacher efficacy was assessed at five time points using the Science Teacher Efficacy Beliefs Instrument (STEBI), and instructional practice was evaluated at four time points with classroom observations using the Reformed Teaching Observation Protocol (RTOP). Results indicate that there was significant growth in teacher self‐efficacy but not in outcome expectancy. There was also significant growth in the extent to which teachers implemented inquiry‐based instruction in the classroom. Additionally, a positive correlation was observed between changes in self‐efficacy and changes in the use of inquiry‐based instructional practice. These results are discussed in terms of a model of teacher learning wherein changes in teacher beliefs and changes in classroom practice mutually influence each other, and also in terms of the impact of collaboration on teacher efficacy and practice. © 2010 Wiley Periodicals, Inc., Inc.

The impact of media multitasking on learning

While multitasking is not a new concept, it has received increasing attention in recent years with the development of new media and technologies. Recent trends appear to suggest that multitasking is on the rise among the younger generation. The purpose of the study is to determine if students obtain more or less information in multitasking conditions. We examined the relationships of multitasking to attention, cognitive load and media with 130 college student participants. In this study, participants were given a timed (16 minutes) reading comprehension test in three conditions: Silence (only reading), Background multitasking (reading with a non-tested video shown simultaneously), and Test multitasking (reading with a tested video shown simultaneously) conditions. Our findings indicated that: (1) participants in the Background condition performed as well as those in the Silence condition, and (2) when participants were tested on their video comprehension, the group in the Test condition performed significantly better than the group in the Background condition. The results of this study suggest that cognitive load plays an important role in determining how much information is retained when students perform more than one task at a time.     

The affective dimensions of learning science

In this study, we identified middle school and college students' prior ideas about electrostatic induction and interviewed them through presenting observational evidence which supported or refuted their own prior ideas. Their responses to the evidence were interpreted from perspectives based on philosophies of science, especially the Popperian and Lakatosian views of scientific hypothesis testing. In the process of confirmation, almost all of the students showed a logical error known as an 'error of affirmation of the consequent' in a syllogism. The students' falsification processes were classified into two groups: those which rejected the hard core of prior ideas, and those which modified the students' protective belt of auxiliary ideas related to the hard core while still preserving the hard core. From an analysis of the students' falsification processes, it was found that the Lakatosian rather than the Popperian view was more acceptable in understanding the students' responses to the conflicting evidence. It was observed that the quality of the understanding of auxiliary ideas should also play an important role in the changing of core concepts.     

The effect of imagery generation on science rule learning

This study was designed to investigate the effect of teacher-induced imagery generation on rule recall and transfer. The independent variables were the degree of imagery encouragement during instruction and the reported utilization of images while performing problem solving tasks on a criterion test. The dependent variable was scores on the criterion test. The results of the study indicate that imagery utilization significantly facilitates rule recall and also that imagery encouragement during instruction leads to significant rule transfer gains for low imagery students. The implications of these findings for teaching are addressed.     

The impact of science curricula on student views about the nature of science

This review of the literature focused on three decades of research related to precollege student understandings about the nature of science. Various interpretations of what aspects characterize the nature of science were examined, revealing an agreement among scientists, science educators, and those involved in policy-making arenas that the nature of science is multifaceted and an important component of scientific literacy. A summary of the research regarding the adequacies of student conceptions about the nature of science revealed inconsistent results. Although the majority of studies show that student understandings are less than desirable, there is research that indicates that student conceptions are acceptable. Research on the impact of instructional materials and techniques on student understandings was also reviewed. The effects of language in science instruction, the content emphasis of instructional materials, integrated science curricula, and instruction in general were curricular variables found to have a negative impact on student understandings about the nature of science. Empirical evidence about the success of innovative instructional materials and techniques designed to facilitate more adequate understandings of the nature of science is needed.     

The impact of computer-mediated interaction on distance learning

Distance‐learning courses were classified with regard to their use of computer‐mediated interaction and the degree to which such interaction was integrated into the curriculum and the assessment regime. This produced four groups of courses varying according to their use of interaction and integration. The impact of interaction and integration was investigated in terms of their effects on students' performance, their perceptions of academic quality and their approaches to studying. In all three respects, variations within the groups of courses proved to be more important than variations between the groups. Interpretation of these results suggests that the adoption of interactive environments within computer‐mediated learning may not be enough in itself to lead to positive learning outcomes. We found no evidence for this assumption in terms of students' completion rates, pass rates, grades, perceptions of the quality of their courses or approaches to studying. Large variations in the measured indicators were found between courses, and these appeared to be largely independent of the effects of interaction and integration. Courses may differ markedly with regard to how they make use of computer‐mediated interaction and how this is integrated into the curriculum and the assessment regime. A case study approach is suggested as being more likely to identify the impact of specific designs based on computer‐mediated interaction and to bring together the diverse student responses arising from the use of such interaction in their studies.     

The impact of higher education on lifelong learning

The UK’s National Adult Learning Survey has emphasised that graduates are more likely than other groups of people to engage in further learning and to be motivated by the intrinsic nature of the subject matter. However, beyond this we know relatively little about the learning of graduates as a specific group. In particular, we know very little about how experiences of higher education affect attitudes towards learning in the years after graduation. To start to redress this gap, this paper draws on in‐depth interviews with 90 graduates from six different UK higher education institutions, five years after they completed their first degree. It argues that, in the case of many of these young adults, the influence of higher education on further learning was exerted at three levels in relation to: the process of learning; the construction of learner identities; and understandings of the relationship between learning and the wider world.     

Space matters: The impact of formal learning environments on student learning

The objective of this research is to identify the relationship between formal learning spaces and student learning outcomes. Using a quasi‐experimental design, researchers partnered with an instructor who taught identical sections of the same course in two radically different formal learning environments to isolate the impact of the physical environment on student learning. The results of the study reveal that, holding all factors excepting the learning spaces constant, students taking the course in a technologically enhanced environment conducive to active learning techniques outperformed their peers who were taking the same course in a more traditional classroom setting. The evidence suggests strongly that technologically enhanced learning environments, independent of all other factors, have a significant and positive impact on student learning.     

The impact of scienceware and foundations on students' attitudes towards science and science classes

In this paper, we describe changes in students' ideas about science classes, attitudes about science, and motivations for studying science, in a classroom designed to support projectbased science learing. Using a survey designed to provide a measure of students' attitudes towards science classes and science, we have compared students enrolled in a traditional high school biology course, with students enrolled in an integrated, project-based science course called Foundations I. Survey responses were analyzed to look at differences between and within two groups of students over the course of one school year. In general, the results of this study suggest that providing students with opportunities to collect and analyze their own data in science classes results in a change in students' ideas about science classrooms. Foundations I students' increased tendency to agree with statements about using information, drawing conclusions, and thinking about problems, implies a change in their understanding of what it means to do science in school. These students, in contrast to students in the traditional Biology course, no longer describe their science experience as one of memorization, textbook reading, and test taking. Instead they see science class as a place in which they can collect data, draw conclusions, and formulate and solve problems.     

The impacts of a web-aided instructional simulation on science learning

This research investigated the effects of selected characteristics of a web-aided instructional simulation on students' conceptual change, problem solving and transfer. A two-pronged research study was conducted using 117 students enrolled in a beginning meteorology course at Iowa State University. For the experimental design, the performances of three groups (the with-log group, the without-log group and the control group) were compared on post-test scores and a weather forecasting activity. No statistically significant differences ( p < 0.05) were found among the groups on these measures. However, follow-up interview data obtained from five diverse students in the treatment group showed that the simulation with authentic situations, multiple representations and the capability of reviewing previous actions supported science learning. For the student who was able to readily take advantage of the information contained in the log and graphs, the simulation exercises were quickly completed and a sufficient understanding of the concept was developed to transfer the newly-gained knowledge to new situations, weather forecast exercises. For others, the simulation was less effective. Only one interviewee showed all three stages of Goos and Galbraith's model of problem solving. This student also demonstrated a better understanding of how to transfer newly-gained knowledge to weather forecast exercises. The other four interviewees, who did not show the features of all the stages, needed the teachers' facilitation to develop their problem-solving skills in order to achieve optimal learning when using the instructional simulation.

The ‘Power Test’: its impact on student learning in a materials science course for engineering students

This paper explores the impact on students’ learning of a change in assessment in a materials science course for engineers. The theory behind the move is discussed with reference to previous work on developing deeper approaches to learning in students at university. The new concept adopted was a ‘power test‘ — an open book format final exam, with extended time and opportunities for colleague interaction. Student response was evaluated by interviews and structured group discussions using a nominal group technique and outcomes were assessed by classification of student exam answers using the SOLO taxonomy of Biggs & Collis (1982). Results were compared with those of students taking the same course in the previous year but who were assessed by standard closed book exam. Problems associated with the introduction of such a novel course assessment to an otherwise traditional degree are discussed.     

The impact of action learning on analysis of occupation

Technology and millennials have created a shift in the world and how it operates. This impact has been experienced in the field of occupational therapy education. As a result of this paradigm shift, an analysis of effective teaching methodologies was carried out to assess the most effective way to engage the millennials in an analysis of occupation process, which is a critical foundation for effective critical thinking and clinical practice for occupational therapists. An action learning assignment was utilized to bridge this gap. The action learning assignment immersed the students in a safe learning environment that recreated many types of domains that needed to be analyzed. As a result, the students experienced first-hand the outcomes of effective and ineffective analysis and problem-solving during their action learning project. Therefore, the students were able to reflect and critically think through alternatives and hear about other students' projects. Overall, the action learning project yielded positive learning and engaging outcomes.
