Contribution of Meta‐strategic Knowledge to Scientific Inquiry Learning

The aim of the present study is to explore the effects of Meta‐strategic Knowledge (MSK) on scientific inquiry learning. MSK is a subcomponent of metacognition defined as general, explicit knowledge about thinking strategies. Following earlier studies that showed considerable effects of explicit instruction of MSK regarding the strategy of variables control, the present study explores whether similar effects are found in two additional scientific thinking strategies: Define Research Questions and Formulate Research Hypotheses. Participants were 119 eighth‐grade students from six classes of a heterogeneous school. Equal numbers of low‐achieving and high‐achieving students were randomly assigned into experimental and control groups. The findings showed dramatic developments in students’ performance following instruction. The effect of the treatment was preserved in a delayed transfer test. Our findings show that explicit teaching of MSK had a stronger effect for low‐achieving students than for high‐achieving students. The implications of the findings for teaching and learning in the context of scientific inquiry are discussed.     

Investigating the Intertwinement of Knowledge,Value, and Experience of Upper Secondary Students’ Argumentation Concerning Socioscientific Issues

This study aims to explore students’ argumentation and decision-making relating to an authentic socioscientific issue (SSI)—the problem of environmental toxins in fish from the Baltic Sea. A multi-disciplinary instructional module, designed in order to develop students’ skills to argue about complex SSI, was successfully tested. Seven science majors in the final year of their upper secondary studies participated in this study. Their argumentation and decision-making processes were followed closely, and data were collected during multiple stages of the instructional module: group discussions were audio recorded, the participants wrote reports on their decision making, and postexercise interviews were conducted with individual students. The analysis focused on the skill of evaluation demonstrated by the students during the exercise and the relationships between the knowledge, values, and experiences that they used in their argumentation. Even though all of the students had access to the same information and agreed on the factual aspects of the issue, they came to different decisions. All of the students took counter-arguments and the limitations of their claims into account and were able to extend their claims where appropriate. However, their decisions differed depending on their background knowledge, values, and experiences (i.e., their intellectual baggage). The implication to SSI teaching and learning is discussed.     

Students’ Experience of Working with Socioscientific Issues - a Quantitative Study in Secondary School

This research project aims to investigate how students in lower secondary school experience work with socioscientific issues (SSI). The six socioscientific cases developed and used in this project are relevant according to characteristics of SSI and to the national curriculum. Approximately 1,500 students in Sweden have worked with one SSI case chosen by the teachers. A questionnaire-based instrument was used to measure the affective domain of students?? attitudes towards and interest in science before starting to work with the case and a second questionnaire after finishing a case. The second student questionnaire, measured the situational characteristics of the SSI work and perceived cognitive and affective outcomes. According to the students?? self-reported experience, all cases were interesting and related to a current issue. Most cases were equally interesting to boys and girls, the only exception was You are what you eat, which girls found more interesting than boys did. Almost all students claim that they learnt new facts, learnt to argue for their standpoint and to search and evaluate information during the work with the cases. The girls?? average scores were higher on several aspects of learning outcomes. Furthermore the students, especially the girls, perceived that the outcome of working with SSI had relevance for their future, with some cases more relevant than others. The more interesting the student found the case, the more they claimed they learnt. The students do not, however, claim that they learnt more science than during ordinary lessons.

Impacts of Multi‐representational Instruction on High School Students’ Conceptual Understandings of the Particulate Nature of Matter

This quasi‐experimental study examined 42 high school introductory chemistry students’ conceptual understandings of the particulate nature of matter (PNM) before and immediately after instruction. Two groups of students, who were taught by the same teacher, received one of two possible instructional interventions: Reform‐Based Teaching (RBT) or Reform‐Based Teaching with Multiple Representations (RBTw/MR). The RBTw/MR instruction differed from the RBT instruction in terms of the frequency of using multiple representations (visual, textual, oral) in relationship to the macroscopic phenomenon and the likely actions occurring at the submicroscopic level. Qualitative research methods, including open‐ended questionnaires and interviews, were used to investigate and describe participants’ conceptual understandings of the PNM over time. The findings indicated that before instruction all participants held a range of alternative conceptions about the aspects of the PNM. Post‐instruction findings indicate that the RBTw/MR instruction was more efficacious in promoting a scientific understanding of the PNM than was the instruction without multiple representations.     

Students’ Participation in an Interdisciplinary, Socioscientific Issues Based Undergraduate Human Biology Major and Their Understanding of Scientific Inquiry

The purpose of this study was to examine whether Socioscientific Issues (SSI) based learning environments affect university students’ epistemological understanding of scientific inquiry differently from traditional science educational contexts. We identify and compare conceptions of scientific inquiry of students participating in an interdisciplinary, SSI-focused undergraduate human biology major (SSI) and those participating in a traditional biology major (BIO). Forty-five SSI students and 50 BIO students completed an open-ended questionnaire examining their understanding of scientific inquiry. Eight general themes including approximately 60 subthemes emerged from questionnaire responses, and the numbers of students including each subtheme in their responses were statistically compared between groups. A subset of students participated in interviews, which were used to validate and triangulate questionnaire data and probe students’ understanding of scientific inquiry in relation to their majors. We found that both groups provided very similar responses, differing significantly in only five subthemes. Results indicated that both groups held generally adequate understandings of inquiry, but also a number of misconceptions. Small differences between groups supported by both questionnaires and interviews suggest that the SSI context contributed to nuanced understandings, such as a more interdisciplinary and problem-centered conception of scientific inquiry. Implications for teaching and research are discussed.     

Assessment of Morale in Further Education Students Studying for A‐level Examinations

This paper reports the results of an empirical study of psychological morale in further education students. Success in A‐level examinations is dependant on a number of factors, not only intellectual ability but also morale and other personality factors. This investigation aimed to assess the influence of these factors in the 16–18 years age range. The sample consisted of 357 A‐level students (156 male and 201 female). Students were asked to complete a number of inventories measuring various dimensions of personality, including morale, self‐esteem, extraversion, neuroticism, psychoticism and state and trait anxiety. Significant and positive correlations of morale with self‐esteem and extraversion were reported. Significant but negative correlations of morale with neuroticism and state and trait anxiety were reported. A factor analysis of the Well‐being Inventory revealed that the most significant factor was student optimism and belief in their future, but this was often moderated by the influence of anxiety. These findings have implications not only for the students who were participants in this investigation but also managers and teachers in further education colleges.     

The Difficult Process of Scientific Modelling: An analysis of novices' reasoning during computer‐based modelling

Although computer modelling is widely advocated as a way to offer students a deeper understanding of complex phenomena, the process of modelling is rather complex itself and needs scaffolding. In order to offer adequate support, we need a thorough understanding of the reasoning processes students employ and of difficulties they encounter during a modelling task. Therefore, in this study 26 students, working in dyads, were observed while working on a modelling task in the domain of physics. A coding scheme was developed in order to capture the types of reasoning processes used by students. Results indicate that most students had a strong focus on adjusting model parameters to fit the empirical data with little reference to prior knowledge. The successful students differed from the less successful students in using more prior knowledge and in showing more inductive reasoning. These observations lead to suggestions for the design of appropriate scaffolds.     

An Investigation of Text‐based Instructional Materials Enhanced with Graphics

ABSTRACT An adaptation of Bagley's (1990) experiment which compared the interaction of instructional format with adult learners was carried out replacing the Wechsler Adult Intelligence Scale (WAIS) arithmetic reasoning subtest with the Riding & Cheema (1991) Cognitive Styles Analysis (CSA). There was an additional inclusion of graphics to the structured instructional format, as an independent variable. A total of 45 participants attended workshops to learn how to write PASCAL programs. All of the participants completed the CSA and their CSA‐ratio was used to select pairs of similar CSA‐ratios. One participant from each pair was given a text‐only instructional booklet, while the other was given a text‐plus‐graphics instructional booklet. The treatment groups were controlled for instructional format (text‐only/text‐plus‐graphics) and cognitive style. The independent variables were used to test for their effect on learning abstract computer programming concepts. It was found that the Verbal‐Imagery cognitive style and instructional treatment interacted in their effect on the performance‐difference scores. The Novice‐Verbal programmers performed best with a text‐plus‐graphics instructional format, performing significantly better than the Novice‐Imagers’ subgroups using the same text‐plus‐graphics material. Conversely, the Novice‐Imagers participants performed better with the material. However, the Experienced‐Imagery participants performed better with the text‐plus‐graphics instructional material than the Experienced‐Verbalisers. Overall, the Verbalisers’ worst performance occurred with the text‐only materials, while their best performance occurred with the text‐plus‐graphics material. This pilot experiment suggests that learning performance is affected by an interaction of cognitive style and instructional format. However, this interaction was contrary to expectations (Riding & Douglas, 1993), with Verbalisers performing best with text‐plus‐graphics instructional material and Novice‐Imagers performing best with text‐only instructional material.     

The Assessment of Student Teachers’ Academic and Professional Knowledge in School‐Based Teacher Education

The aim of this study was to scrutinize the assessment of teacher knowledge in a school‐based course at one Swedish pre‐service teacher education program. In a general education school‐based course, teacher educators visited the student teachers at their school placements and met them and their school mentors in student‐teaching conferences to assess their teacher knowledge. The findings primarily show that the assessment procedures are influenced by teacher educators’ organization of the school visits and conferences. Secondly, the organization of the school visits and conferences influences who the potential and actual assessors at the conferences can be and are. Thirdly, the assessed student teacher knowledge at the conferences is described as procedural knowledge in a knowledge‐in‐practice perspective, almost exclusively in the area of relational, emotional, and caring learning objectives and aspects of teaching activities. Fourthly, the findings show that propositional knowledge in a knowledge‐for‐practice perspective is hardly mentioned or assessed.     

Delivering the DEAL: implementation of a work‐based learning programme at degree level

Abstract

This paper offers a strategy for the development of successful work‐based learning programmes within higher education. It identifies and addresses the key challenges facing such development. Firstly, whether it is possible to develop a work‐based learning programme which provides an effective learning experience at higher education level and which draws upon opportunities within the workplace. Secondly, whether work‐based learning programmes are an appropriate vehicle for structuring and accrediting the continuing development of the workforce. In addressing these challenges, we examine the design and quality assurance of a work‐based learning programme for qualified social workers, placing particular emphasis on the development of an appropriate learning model. We consider some of the criticisms levelled at competence‐based education and argue that work‐based learning programmes composed of learning outcomes achieved entirely through practice can be compatible with the aims of higher education.     

The effect of computer‐based multimedia instruction with Chinese character recognition

The purpose of this study was to examine second language learners’ learning achievement and attitudes toward two different types of dual coding designs (text group: image plus on‐screen text versus narration group: image plus narration) in Chinese character acquisition. A total of 66 college students who did not have prior knowledge of the Chinese language were randomly assigned to either the text group or narration group. The findings showed that there was no interaction between the treatments (text group versus narration group) and test occasions (immediate and delayed post‐tests), and there was no significant difference between two groups in the immediate post‐test and in the delayed post‐test. However, there was a significant difference between the test occasions. Furthermore, the results revealed that there was no significant difference between two groups in both the tutorial design factor and the cognitive load factor. Overall, participants in both groups achieved high scores in the post‐tests and showed positive attitudes toward the dual coding tutorials.     

Design,Assessment, and Evaluation of a Problem‐based Learning Environment in Undergraduate Engineering

This article describes the design, evaluation, and results of an innovative undergraduate engineering course at the U.S. Air Force Academy (USAFA). The course, ENGR 110 — Introduction to Engineering, is a problem‐based learning environment in which freshmen students work in teams to solve problems integral to a “mission to Mars”, that is, getting to Mars, constructing a research site on Mars, and developing a renewable power source there. In addition to traditional knowledge and skill objectives, the course focuses on “higher order” outcomes such as: framing and resolving ill‐defined problems; communicating via multiple media; exhibiting intellectual curiosity; and developing a rich conceptualisation of engineering. The course is described in terms of a set of pedagogical dimensions for problem‐based learning environments. Several cognitive assessment methods were used to assess student achievement and evaluate the effectiveness of the course. Results included statistically and educationally significant differences in “problem‐solving” between two classes of ENGR 110 students and two control classes of sophomore engineering students.     

The Relationship between Students' Connections to Out‐of‐School Experiences and Factors Associated with Science Learning

This study examined the relationship between students' out‐of‐school experiences and various factors associated with science learning. Participants were 1,014 students from two urban high schools (secondary schools). They completed a survey questionnaire and science assessment describing their science learning experiences across contexts and science understanding. Using multilevel statistical modelling, accounting for the multilevel structure of the data with students (Level 1) assigned to teachers (Level 2), the results indicated that controlling for student and classroom factors, students' ability to make connections between in‐school and out‐of‐school science experiences was associated with positive learning outcomes such as achievement, interest in science, careers in science, self‐efficacy, perseverance, and effort in learning science. Teacher practice connecting to students' out‐of‐school experiences was negatively associated with student achievement but has no association with other outcome measures. The mixed results found in this study alert us to issues and opportunities concerning the integration of students' out‐of‐school experiences to classroom instruction, and ultimately improving our understanding of science learning across contexts.     

Experienced Middle School Science Teachers’ Assessment Literacy: Investigating Knowledge of Students’ Conceptions in Genetics and Ways to Shape Instruction

Using a framework of assessment literacy that included teachers?? view of learning, knowledge of assessment tools, and knowledge of assessment interpretation and action taking, this study explored the assessment literacy of five experienced middle school teachers. Multiple sources of data were: teachers?? predictions about students?? ideas, students?? written and verbal responses to assessment tasks, teacher background questionnaire, and a videotaped teacher focus group. We investigated middle school teachers?? predictions, interpretations, and recommended actions for formative assessment in genetics. Results documented a variety of ways that teachers would elicit students?? ideas in genetics, focusing on discussion strategies. Findings showed how well teachers predicted student conceptions compared to actual student conceptions. We also found that teachers mostly described general topics they would use to address students?? alternative conceptions. Less often, they explained specific content they would use to challenge ideas or pedagogical strategies for conceptual change. Teachers also discussed barriers to addressing ideas. Teacher professional development should provide more support in helping teachers close the formative assessment cycle by addressing conceptions that are elicited with assessments.     

Considerations in Assessment of Children with Severe Disabilities including Deaf‐Blindness and Autism

This paper will discuss the difficulties in assessment of autistic and deaf‐blind children with such severe difficulties in communication that they are often labelled as untestable and subsequently misdiagnosed as severely to profoundly mentally retarded. It will go on to make the case for nonintrusive assessment and appropriate intervention as the most relevant procedures for helping this population advance educationally and in life skills. While this paper will focus on children, the points made apply to individuals of all ages.
