Knowledge and Technique in Statistical Problem‐Solving

Summaries

English

Subjects’ knowledge and technique in statistical problem‐solving, as well as their ability to detect their own problem‐solving errors, were studied. Twenty subjects were asked to solve two statistical problems, and then to explain their solutions to the experimenter. Finally, each subject was asked successively more detailed questions about his/her solution, particularly in reference to its erroneous parts. The results showed that subjects tended to describe rather than explain their solutions. Subjects eliminated three errors (4%) when accounting for their solutions and another 20 errors (24%) in the following interview. About one‐third of all errors were analysed as being due to deficiencies in subjects’ problem‐solving techniques. For 62% of the errors where subjects showed knowledge deficiencies, there were deficiencies in propositional knowledge, i.e. in subjects’ understanding of statistical concepts and their interrelations. The results showed that misunderstandings of concepts and methods of solution were much more common than lack of conceptions as such. In addition, the results suggest that deficiencies in subjects’ problem‐solving are related to motivational factors, such as a tendency to minimize cognitive strain. Pedagogical implications of the results are discussed.     

A Longitudinal Study of Children’s Developing Knowledge and Reasoning in Science

The growth in science understanding and reasoning of 12 children is being traced through their primary school years. The paper reports findings concerning children’s growing understandings of evaporation, and their changing responses to exploration activities, that show the complexity and coherence of learning pathways. Children’s responses to identical explorations of flight, separated by two years, are used to explore the interactions between conceptual knowledge and scientific reasoning, and the manner in which they change over this time. The paper discusses the particular insights afforded by a longitudinal study design, and some attendant methodological issues.     

Does Higher Education Improve Student Scientific Reasoning Skills?

An ultimate goal of higher education is to prepare our future workers with needed knowledge and skills. This includes cultivating students to become proficient reasoners who can utilize proper scientific reasoning to devise causal inferences from observations. Conventionally, students with more years of higher education are expected to have a greater level of scientific reasoning. Also expected traditionally is that studying science and engineering or attending top-rated universities can better promote students’ scientific reasoning than studying other majors or attending lower ranked institutions. In this study, we used Lawson’s Classroom Test of Scientific Reasoning (LCTSR) with 1,637 Chinese students in different years of study, different fields, and different university tiers. It was found that regardless of which major or university students entered, their scientific reasoning measured by the LCTSR showed little variation across the entire 4 years of undergraduate education. Simply put, there was little association between tertiary-level learning and scientific reasoning. This study calls our attention to the status quo of higher education and motivates researchers across the globe to look into this issue in their own nations.     

How Does the Degree of Guidance Support Students’ Metacognitive and Problem Solving Skills in Educational Robotics?

Educational robotics (ER) is an innovative learning tool that offers students opportunities to develop higher-order thinking skills. This study investigates the development of students’ metacognitive (MC) and problem-solving (PS) skills in the context of ER activities, implementing different modes of guidance in two student groups (11–12 years old, N1 = 30, and 15-16 years old, N2 = 22). The students of each age group were involved in an 18-h group-based activity after being randomly distributed in two conditions: “minimal” (with minimal MC and PS guidance) and “strong” (with strong MC and PS guidance). Evaluations were based on the Metacognitive Awareness Inventory measuring students’ metacognitive awareness and on a think-aloud protocol asking students to describe the process they would follow to solve a certain robot-programming task. The results suggest that (a) strong guidance in solving problems can have a positive impact on students’ MC and PS skills and (b) students reach eventually the same level of MC and PS skills development independently of their age and gender.

Students’ Ability to Apply Their Knowledge in a Gaming Exercise: An Exploratory Study

This paper reports on a study exploring master students’ ability to apply their knowledge when solving an internal pricing problem in a supply chain. Analyses of 33 negotiation progress reports and 8 recordings of discussions demonstrate that most of the students were not able to apply relevant concepts and models to guide their handling of the task. The main reason for the variability in performance was the significant differences in the students’ general problem-solving abilities. Most students did not perform a thorough task analysis or develop a solution strategy before they met for negotiations, and they did not keep track of their task performance. The implications for teaching are highlighted, and directions for further research are proposed.     

Interpersonal Neural Synchrony During Father–Child Problem Solving: An fNIRS Hyperscanning Study

Interpersonal neural synchrony (INS) has been previously evidenced in mother–child interactions, yet findings concerning father–child interaction are wanting. The current experiment examined whether fathers and their 5- to 6-year-old children (N = 66) synchronize their brain activity during a naturalistic interaction, and addressed paternal and child factors related to INS. Compared to individual problem solving and rest, father–child dyads showed increased INS in bilateral dorsolateral prefrontal cortex and left temporo-parietal junction during cooperative problem solving. Furthermore, the father’s attitude toward his role as a parent was positively related to INS during the cooperation condition. These results highlight the implication of the father’s attitude to parenting in INS processes for the first time.     

Impact of Secondary Students’ Content Knowledge on Their Communication Skills in Science

The expert blind spot (EBS) hypothesis implies that even some experts with a high content knowledge might have problems in science communication because they are using the structure of the content rather than their addressee’s prerequisites as an orientation. But is that also true for students? Explaining science to peers is a crucial part of cooperative learning methods such as the “jigsaw method”. Our study examined the relationship between science communication competence (SCC) and content knowledge (CK) of 10th-grade students (N = 213). Using latent class analysis, we identified two types of students with a different relationship between CK and SCC. Using path analysis, we found that the first type of 109 students primarily used their science CK as the “resource” for addressee-oriented science communication and both their SCC and their CK were correlated with each other. For the second type of 104 students (who used other resources), their CK even had a small negative effect on their SCC. Using t tests, we found that those students primarily using their CK as the resource for communication performed significantly worse in the communication test than did those students who used other resources. Using the EBS hypothesis, we suggest that students’ CK might have ambiguous effects in communication if the content structure—rather than their addressee’s prior knowledge—is used as the primary orientation for communication. We suggest that an effective use of cooperative learning techniques in classroom requires a special prior training for their science communication skills.     

An Exploratory Case Study of Olympiad Students’ Attitudes towards and Passion for Science

Much is known about high school students’ attitudes towards science but there is almost no research on what passion for science might look like and how it might be manifested. This exploratory case study took advantage of a unique group of highly gifted science students participating in the Australian Science Olympiad (N = 69) to explore their attitudes towards school science and science as presented in the Olympiad summer camp. In particular the role the summer camp might play in igniting the students’ passion for science was a focus of the research. Data were collected through a two-tiered survey of students’ attitudes towards school science, an evaluative survey of the Olympiad summer camp and in-depth interviews with six participants. Findings indicated that Olympiad students generally had positive attitudes towards school science with most selecting science as one of their favourite subjects. However, an underlying ambivalence about school science was noted in the data. In contrast, the Olympiad summer camp transformed students’ positive attitudes into passion for science. Seven themes emerged from the data providing a foundation for a model of what academic passion for science looks like.     

An Exploratory Study of Teachers’ and Students’ Use of Multi‐modal Representations of Concepts in Primary Science

As part of a long‐term research study to enhance science learning, this paper reports on an exploratory study aimed at identifying initial beliefs and practices of a group of teachers and students (Years 4–6) in Australia when the students engaged with multiple representations of the same science concepts. There is growing recognition in science education research that students need to understand and link different representational modes, such as graphic and verbal modes, in learning to think and act scientifically. This exploratory study used a multi‐site case‐study approach employing qualitative and quantitative methods. The findings indicated that while teachers used various modes to engage students and assess learning, they were not systematic in their focus on student integration and translation across modes. The study found that various factors affected students’ understanding of different modes, and that students who recognised relationships between modes demonstrated better conceptual understandings than students who lacked this knowledge.     

Tacit Knowledge in Expert Coaching: Science or Art?

Effective coaching is a mixture of pedagogy and principles of sciences, e.g., motor skill acquisition, sociology, and physiology, often referred to as the science of coaching. Instinctive or intuitive coaching has often been incorrectly viewed as the art of coaching. More important should be how coaches develop knowledge, how they access that knowledge at the appropriate times and how this affects their decision-making process. The study of expert coaches should allow inferences to be drawn from their development and applied to coach education. This article intends to clarify coaching expertise and examine the role of tacit knowledge within coaching. The lack of a clear development pathway for aspiring expert coaches is a clear indicator that the current coach education system needs review. Any effective education system should be based on knowledge and understanding rather than mimicry and the implications for the future of coach education are considered.     

Teachers’ Use of YouTube in the United Arab Emirates: An Exploratory Study

Teachers around the world are using YouTube movies for different purposes. This mixed-methods study was a preliminary investigation of United Arab Emirates teachers’ perceptions about YouTube's advantages in the classroom, current practices, and major challenges faced. Forty-five teachers completed an open-ended questionnaire. Results indicated that perceived advantages included supporting the learning process, increasing interest and efficiency, and enriching content. Moreover, findings revealed that the majority of participants were using videos for presentation purposes in teacher-led classrooms. Connectivity, technical issues, appropriateness of content, and administrative support were perceived as major challenges.     

Does Doing Scientific Research in High School Correlate with Students Staying in Science? A Half-Century Retrospective Study

The American Association for the Advancement of Science (AAAS) has declared in an advertising campaign that “you can’t start young enough” in science. However, there is no long-term data evaluating the effect of early exposure to original scientific research on producing career scientists. To address this issue, we examined a hands-on summer science research program for high school students that ran from 1958 to 1972. We compared participants in that program with science students that only began their hands-on research experience once in university. Our data indicate that students who are interested in science and have an opportunity to participate in original scientific research while in high school are significantly more likely (p < .005) to both enter and maintain a career in science compared to students whose first research experience didn’t occur until university. Our data suggest that more hands-on high school science research programs could help increase the number of students entering and maintaining scientific careers, relieving the growing concern that North America is losing its leadership status in the international scientific community.

Does Self-image Matter? Client’s Self-image, Behaviour and Evaluation of a Career Counselling Session: An Exploratory Study

This exploratory study addresses differences in self-image as a client characteristic in career counselling by using the Structural Analysis of Social Behaviour (Benjamin, L., Journal of Consulting and Clinical Psychology, 64(6), 1203–1212, 1996; Benjamin, L., Journal of Personality Assessment, 66(2), 248–266, 1996) and an adaptation (Andersson, W.P, and Niles, S.P., The Career Development Quarterly, 48(3), 251–263, 2000) of the Therapist Intention List (Hill C. E and O’Grady K. E., Journal of Counseling Psychology, 32(1), 3–22, 1985; Hill et al., Journal of Counseling Psychology, 35(3), 222–233, 1988). Expected and experienced behaviour of self and other, recalled helpful and non-helpful events during sessions, and evaluation of sessions were compared between two clients with identified positive self-image and two clients with identified negative self-image. The results indicated that the clients with a positive self-image compared to clients with a negative self-image expected more positive behaviours and experienced more positive in-session behaviours from both themselves and from the counsellor; they recalled more positive and fewer negative events in-session and they evaluated their session more positively. Implications for career counselling are discussed.     

Confidence versus Performance as an Indicator of the Presence of Alternative Conceptions and Inadequate Problem‐Solving Skills in Mechanics

This study investigated the use of performance–confidence relationships to signal the presence of alternative conceptions and inadequate problem‐solving skills in mechanics. A group of 33 students entering physics at a South African university participated in the project. The test instrument consisted of 20 items derived from existing standardised tests from literature, each of which was followed by a self‐reported measure of confidence of students in the correctness of their answers. Data collected for this study included students’ responses to multiple‐choice questions and open‐ended explanations for their chosen answers. Fixed response physics and confidence data were logarithmically transformed according to the Rasch model to linear measures of performance and confidence. The free response explanations were carefully analysed for accuracy of conceptual understanding. Comparison of these results with raw score data and transformed measures of performance and confidence allowed a re‐evaluation of the model developed by Hasan, Bagayoko, and Kelley in 1999 for the detection of alternative conceptions in mechanics. Application of this model to raw score data leads to inaccurate conclusions. However, application of the Hasan hypothesis to transformed measures of performance and confidence resulted in the accurate identification of items plagued by alternative conceptions. This approach also holds promise for the differentiation between over‐confidence due to alternative conceptions or due to inadequate problem‐solving skills. It could become a valuable tool for instructional design in mechanics.     

Does Gender Matter? an Exploratory Study of Perspectives Across Genders, Age and Education

Using a convenience sample and survey research methods, the authors seek to better understand how perspectives on gender are shaped by individuals’ age, level of education and gender. Study participants responded in writing to scenarios and survey questions, revealing their personal views on gender as an identity category and as a marker in the social hierarchy. Analysis indicated that there were differences between male and female views on these dimensions of gender, and that age and educational levels were also influential. While younger respondents from both genders demonstrated flexibility in their definitions of gender and expressed strong support for gender equality, they were noticeably lacking in their knowledge of the historical context of gender relations and did not show the skills required to realise their ideals of gender equality, especially when compared to older respondents of both genders with higher levels of educational attainment.     

Student Self-Assessment in HOCS Science Examinations: Is There a Problem?

A specially-designed self-assessment questionnaire (SAQHOCS), containing higher-order cognitive skills (HOCS)-type questions, was administered to 71 biology majors, enrolled in a four-year college program. The gap between students' self-assessment marking, and that of their HOCS-biased teachers (the authors), is accounted for by the prevailing LOCS-orientation and the testing culture—a total separation between testing and learning—in contemporary science teaching. The majority of the students in the study evaluated themselves as capable of self-assessment, and felt reasonably confident in doing so. They were quite reserved as far as the applicability of the self-assessment method to nonalgorithmic (correct/incorrect) questions is concerned. The results of this study suggest that the potential for student self-assessment within college science teaching and learning exists. However, still a great purposed effort in HOCS-oriented teaching and learning is required in order for the student self-assessment practice to become a routine integral component of HOCS science examinations.
