The Comparative Effects of Prediction/Discussion‐Based Learning Cycle,Conceptual Change Text,and Traditional Instructions on Student Understanding of Genetics

The present study examined the comparative effects of a prediction/discussion‐based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi‐experimental research design of the pre‐test–post‐test non‐equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion‐based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). Participants completed the genetics concept test as pre‐test, post‐test, and delayed post‐test to examine the effects of instructional strategies on their genetics understanding and retention. While the dependent variable of this study was students' understanding of genetics, the independent variables were time (Time 1, Time 2, and Time 3) and mode of instruction. The mixed between‐within subjects analysis of variance revealed that students in both prediction/discussion‐based learning cycle and CCT groups understood the genetics concepts and retained their knowledge significantly better than students in the traditional instruction group.     

LINKING STUDENTS AND CLASSES: STRATEGIES FOR IMPROVING LEARNING AND THINKING

Research in cognitive and social psychology is beginning to suggest strategies which will allow us to improve students’ learning and thinking skills. Classroom studies using four teaching strategies based on research in these areas will be described. The four techniques are: using modified cooperative learning groups within classes; linking upper‐ and lower‐level classes for metacognitive instruction; using short‐term, coached cooperative learning groups; and using student mentors. A common factor in the four techniques is that students think aloud in groups as they solve problems or discuss controversial issues. Modified cooperative learning groups were successful in upper‐level courses. Thinking and learning skills improved in these classes. However, in lower‐level courses, particularly those which contained underprepared students, more guidance (modeling, coaching and structure) was needed than was available within most peer cooperative groups. Modeling and coaching were provided by linking students from upper‐level courses with lower‐level students on short‐term, issue‐based projects and for semester‐long classes. Such arrangements result in what Collins, Brown and Newman (1989) have termed cognitive apprenticeships. Cognitive apprenticeships lead to improved attitudes toward the content area, perception of improved cognitive skills and some gains in content mastery.     

Translating expertise into effective instruction: The impacts of cognitive task analysis (CTA) on lab report quality and student retention in the biological sciences

Poor instruction has been cited as a primary cause of attrition from STEM majors and a major obstacle to learning for those who stay [Seymour and Hewitt [1997]. Talking about leaving: Why undergraduates leave the sciences. Boulder, CO: Westview]. Using a double‐blind design, this study tests the hypothesis that the lack of explicit instructions in scientific inquiry skills is a major factor in both low STEM retention and academic underperformance. This project delivered supplemental instruction to students in a laboratory‐based undergraduate biology course (n = 314) that was derived either from cognitive task analyses (CTAs) conducted with expert biologists (treatment) or was authored and delivered by an award‐winning biology instructor (control). Students receiving traditional instruction were almost six times more likely to withdraw from the course than students in the treatment condition (8.1% vs. 1.4% of initial enrollment). Of the students who completed the course, those who received the CTA‐based instruction demonstrated significantly higher levels of performance in the discussion section of their written laboratory reports. Significantly higher performances were seen specifically in the areas of analyzing data to formulate valid conclusions, considering alternative explanations, consideration for the limitations of the experimental design and implications of the research. © 2010 Wiley Periodicals, Inc.

Effects of learning cycle and traditional text on comprehension of science concepts by students at differing reasoning levels

Research has found the learning cycle to be effective for science instruction in hands‐on laboratories and interactive discussions. Can the learning cycle, in which examples precede the introduction of new terms, also be applied effectively to science text? A total of 123 high school students from two suburban schools were tested for reasoning ability, then randomly assigned to read either a learning cycle or traditional text passage. Immediate and delayed posttests provided concept comprehension scores that were analyzed by type of text passage and by reasoning level. Students who read the learning cycle passage earned higher scores on concept comprehension questions than those who read the traditional passage, at all reasoning levels. This result supports the hypothesis that reading comprehension and scientific inquiry involve similar information‐processing strategies and confirms the prediction that science text presented in the learning cycle format is more comprehensible for readers at all reasoning levels. © 1999 John Wiley & Sons, Inc.

The influence of students’ cognitive and motivational variables in respect of cognitive conflict and conceptual change

In this study, the relationships among students’ cognitive/motivational variables, cognitive conflict, and conceptual change were investigated. Subjects were 159 seventh graders in Korea. Tests regarding logical thinking ability, field dependence/independence (FDI), meaningful learning approach, failure tolerance, mastery goal orientation, and self‐efficacy were administered to examine students’ cognitive/motivational characteristics. A preconception test and a test of responses to discrepant event were also conducted to examine the degree of students’ cognitive conflict induced by a discrepant event. Computer‐assisted instruction, designed to change an undifferentiated weight‐density concept into a scientific density concept, was then provided to students as a conceptual change intervention. A conception test was administered as a post‐test. The results indicated that FDI was the only statistically significant variable correlated with the degree of cognitive conflict. A stepwise multiple regression analysis revealed that logical thinking ability, FDI, and failure tolerance were statistically significant predictors of the conception test scores. Educational implications are discussed.     

Designing Effective Learning Environments for Continuing Education

Advances in technology for distance learning present better‐than‐ever opportunities for designing learning environments that bring optimal features of the conventional classroom to distributed learners. Yet, with the advantages of reaching learners come corresponding challenges for meeting many and varied cognitive, motivational, and organizational needs. Anchoring design of distance learning instruction solidly in current research from cognitive science and motivation, as well as utilizing tested principles of instructional design theory, provides for optimal balance of strategic decision‐making and appropriate management of trade‐offs in design of effective learning environments. This paper shows how Bransford, Brown, and Cocking's (1999) four characteristics of effective learning environments can be developed for continuing education, to maximize learning, transfer of learning, and motivation. As illustration, I will focus on the process of translating traditional continuing education (CE) from lecture‐based, on‐site instruction to Web‐based instruction, a trend in many institutions of higher education.     

Supporting inquiry learning by promoting normative understanding of multivariable causality

Early adolescents may lack the cognitive and metacognitive skills necessary for effective inquiry learning. In particular, they are likely to have a nonnormative mental model of multivariable causality in which effects of individual variables are neither additive nor consistent. Described here is a software‐based intervention designed to facilitate students' metalevel and performance‐level inquiry skills by enhancing their understanding of multivariable causality. Relative to an exploration‐only group, sixth graders who practiced predicting an outcome (earthquake risk) based on multiple factors demonstrated increased attention to evidence, improved metalevel appreciation of effective strategies, and a trend toward consistent use of a controlled comparison strategy. Sixth graders who also received explicit instruction in making predictions based on multiple factors showed additional improvement in their ability to compare multiple instances as a basis for inferences and constructed the most accurate knowledge of the system. Gains were maintained in transfer tasks. The cognitive skills and metalevel understanding examined here are essential to inquiry learning. © 2003 Wiley Periodicals, Inc.

Development of system thinking skills in the context of earth system education

The current study deals with the development of system thinking skills at the junior high school level. The sample population included about 50 eighth‐grade students from two different classes of an urban Israeli junior high school who studied an earth systems‐based curriculum that focused on the hydro cycle. The study addressed the following research questions: (a) Could the students deal with complex systems?; (b) What has influenced the students' ability to deal with system perception?; and (c) What are the relationship among the cognitive components of system thinking? The research combined qualitative and quantitative methods and involved various research tools, which were implemented in order to collect the data concerning the students' knowledge and understanding before, during, and following the learning process. The findings indicated that the development of system thinking in the context of the earth systems consists of several sequential stages arranged in a hierarchical structure. The cognitive skills that are developed in each stage serve as the basis for the development of the next higher‐order thinking skills. The research showed that in spite of the minimal initial system thinking abilities of the students most of them made some meaningful progress in their system thinking skills, and a third of them reached the highest level of system thinking in the context of the hydro cycle. Two main factors were found to be the source of the differential progress of the students: (a) the students' individual cognitive abilities, and (b) their level of involvement in the knowledge integration activities during their inquiry‐based learning both indoors and outdoors. © 2005 Wiley Periodicals, Inc.     

An intervention programme for enhancing kindergarteners' cognitive engagement and comprehension skills through reading informational texts

The purpose of the present study was to investigate whether systematic instruction of informational texts can enhance kindergarteners' cognitive involvement in text discussion and comprehension skills. The sample consisted of 15 children aged 5–6 years old in a kindergarten classroom located in a rural area in Rethymno, Crete. A four‐phase intervention programme was implemented within a 2‐month period. During the first phase, activities were carried out in order to familiarise children with the features of informational texts. During the subsequent phases, reciprocal teaching, What I know ‐ What I want to learn ‐ What I learned (KWL) practice and dialogic reading were used to help children comprehend text information, enhance their cognitive involvement in text discussion and train them in asking literal and inferential questions. The teacher's reading‐aloud sessions were recorded and transcribed. Data showed that the intervention programme helped children recognise the features of informational texts, enhanced their cognitive involvement in text discussion and motivated them to demonstrate comprehension skills that are related to information processing.     

Examining the characteristics of student postings that are liked and linked in a CSCL environment

This case study is the first iteration of a large‐scale design‐based research project to improve Pepper, an interactive discussion‐based learning environment. In this phase, we designed and implemented two social features to scaffold positive learner interactivity behaviors: a “Like” button and linking tool. A mixed‐methods approach was used to examine communicative and cognitive characteristics of notes. Additionally, we develop and apply a new metric for cognitive complexity that acknowledges a range of cognitive behavior valuable to a learning community. The findings suggest that the Like and linking functions positively cultivated and sustained interactive behaviors among students, which also led to an increase in the cognitive complexity of student contributions to the online discussion. Suggestions for future iterations of this project are offered.     

Students’ reasoning about electricity: combining performance assessments with argumentation analysis

Our study monitored the cognitive and motivational effects within different educational instruction schemes: On the one hand, teacher‐centred versus hands‐on instruction; on the other hand, hands‐on instruction with and without a knowledge consolidation phase (concept mapping). All the instructions dealt with the same content. For all participants, the hands‐on approach as well as the concept mapping adaptation were totally new. Our hands‐on approach followed instruction based on “learning at work stations”. A total of 397 high‐achieving fifth graders participated in our study. We used a pre‐test, post‐test, retention test design both to detect students' short‐term learning success and long‐term learning success, and to document their decrease rates of newly acquired knowledge. Additionally, we monitored intrinsic motivation. Although the teacher‐centred approach provided higher short‐term learning success, hands‐on instruction resulted in relatively lower decrease rates. However, after six weeks, all students reached similar levels of newly acquired knowledge. Nevertheless, concept mapping as a knowledge consolidation phase positively affected short‐term increase in knowledge. Regularly placed in instruction, it might increase long‐term retention rates. Scores of interest, perceived competence and perceived choice were very high in all the instructional schemes.     

Effects of a Problem-based Structure of Physics Contents on Conceptual Learning and the Ability to Solve Problems

A model of teaching/learning is proposed based on a ‘problem-based structure’ of the contents of the course, in combination with a training in paper and pencil problem solving that emphasizes discussion and quantitative analysis, rather than formulae plug-in. The aim is to reverse the high failure and attrition rate among engineering undergraduates taking physics. A number of tests and questionnaires were administered to a group of students following a traditional lecture-based instruction, as well as to another group that was following an instruction scheme based on the proposed approach and the teaching materials developed ad hoc. The results show that students following the new method can develop scientific reasoning habits in problem-solving skills, and show gains in conceptual learning, attitudes and interests, and that the effects of this approach on learning are noticeable several months after the course is over.     

Systems Not Projects: focusing on evaluating overall student experience,rather than isolated innovations

This article describes evaluation of the Veterinary Bacteriology and Mycology problem‐based learning multimedia project at the University of Melbourne over a period of seven years. The design of the initial project will be described, together with learning benefits that short‐term evaluations revealed — including better information management skills, improved higher order cognitive skills, increased interest in the subject, better collaborative learning skills, better written and oral communication skills and better computer skills. All very impressive. However, follow‐up studies with staff and students in clinical years of the veterinary course indicated clearly that the positive benefits were not sustained in the long term, as this was a once‐off experience for students. We clearly needed a new approach. Since 1995, the institutional climate, opportunities provided by new technologies and international links have shifted the policy in the Faculty of Veterinary Science towards the development of online problem‐based subjects, hopefully enabling students to have a much greater exposure to a problem‐based learning approach.     

Transition planning and writing instruction: the effects of a brief intervention

This study used a multiple probe design across behaviours to determine if four high school students with learning disabilities could plan post‐school transition goals using a modified GO 4 IT … NOW! intervention while learning essential paragraph and essay writing skills. The results of this study indicate a functional relationship between the intervention and increased writing skills needed for high‐stakes testing and increases in students' knowledge of transition planning. During baseline, students produced extremely short essays and did not include essential paragraph elements. After instruction, students wrote longer compositions and included more details, and paragraphs contained more paragraph elements. All participants increased essay quality during the intervention as measured by the rubric used to evaluate end‐of‐instruction writing prompts.     

Using video-based anchored instruction to enhance learning: Taiwan's experience

The purpose of this study is to investigate the effects of computer-assisted videodisc-based anchored instruction on attitudes toward mathematics and instruction as well as problem-solving skills among Taiwanese elementary students. Results from a t-test indicate a significant main effect on student attitudes toward mathematics. Results from a two-way Repeated Measures ANOVA show that students' problem-solving skills improve significantly with anchored instruction. Results also indicate that all the students benefit from the effects of anchored instruction on their problem-solving performance regardless of their mathematics and science abilities. The findings suggest that video-based anchored instruction provide a more motivating environment that enhanced students' problem-solving skills. This study is significant because it establishes an example of video-based anchored instruction for Taiwanese students and also provides empirical evidence of its effects on affective and cognitive responses among fifth graders in learning mathematics. This study is helpful to educators who want to help students learn to think and learn throughout technology.     

Using the Expressive Writing Program to Improve the Writing Skills of High School Students with Learning Disabilities

Abstract. The complex nature of written expression presents difficulty for many students, particularly those with learning disabilities (LD). The literature in the area of written expression and students with learning disabilities indicates that explicit, rule‐based instruction can enhance the writing skills of struggling students. Research in Direct Instruction (DI) writing programs is promising, but limited at this time to a small number of group design studies. The purpose of this study was to investigate the effects of the DI writing program, Expressive Writing, for high school students with learning disabilities using a single‐subject design methodology. Results indicated that the Expressive Writing program improved the writing skills of the students in this study. Students also were able to generalize and maintain the writing skills learned during intervention.     

Effects of Training in the Use of Social and Cognitive Strategies: An Intervention Study in Secondary Mathematics in Co‐Operative Groups

ABSTRACT

This article reports on an intervention study into the effects of a training in the use of social and cognitive strategies on the learning outcomes of students in secondary mathematics education. Special attention is given to differential effects for high‐ and low‐achieving students. The focus on differential effects is derived from studies into learning in small co‐operative groups, and from the results of meta‐analyses into the effects of training in learning strategies. From these studies it can be concluded that in general such programs contribute to learning. However, it seems that low‐achieving students are unable to benefit from interventions of the kind investigated (i.e., co‐operative learning and training in learning strategies). The main question is whether it is possible to design an instructional program from which all students benefit, and from which the low‐achieving students profit more than their counterparts in the control‐program. In the present study three instructional programs for co‐operative learning were compared: (i) an experimental program with special instruction in the use of social strategies; (ii) an experimental program with special instruction in the use of cognitive strategies; and (iii) a control program without training in either cognitive or social strategies. The programs were identical with respect to mathematical content and general instructional settings (a combination of whole‐class instruction, working in co‐operative groups and individual work). The experiment addressed the following research question: what are the general and differential effects of a training in the use of social and cognitive strategies on the results of learning in secondary mathematics? The research was conducted in two schools for secondary education in a total of 21 classes, involving a total of 511 students. The design was a pretest‐posttest control group design, using two experimental groups and one control group. The data were analysed from a multi‐level perspective. The outcomes of the investigation clearly show the effects of the intervention. Teaching cognitive and social strategies has the expected, positive effects. In addition to this main effect, a compensatory effect for the low‐achieving students was found. The low‐achieving students in the experimental conditions outperformed their counterparts in the control group.

     

Implementing interactive courseware into EFL business writing: computational assessment and learning satisfaction

The implementation of interactive courseware within a task-based learning (TBL) approach was conducted for English Writing for Business to Chinese students in an applied foreign languages department housed in a university of technology. The development of the interactive courseware is based on Mayer’s multimedia learning theory, which allows learners to construct verbal and visual cognitive representations and integrate them; its language learning focus is keyed to Chapelle’s suggested criteria for development of multimedia CALL (computer assisted language learning). According to the curriculum, students had to accomplish three tasks rooted in the real world workplace: inquiry, negotiation, and complaint. Evaluation of the interactive ESP courseware into TBL instruction was based upon data from students’ pre- and post-writing performance measured by three different types of online computational assessments. In addition, a questionnaire survey about learning satisfaction was administered. The results indicate that students had significantly better post-writing performance and showed greater satisfaction after self-studying with the courseware-implemented instruction, which effectively integrated content knowledge, integrative English skills and writing practices embedded in the courseware. This instruction could be a potentially useful for teaching business writing by providing both content knowledge and its related integrative language practice.     

Effects of active‐learning experiences on achievement,attitudes, and behaviors in high school biology

Active‐learning labs for two topics in high school biology were developed through the collaboration of high school teachers and university faculty and staff and were administered to 408 high school students in six classrooms. The content of instruction and testing was guided by State of Texas science objectives. Detailed teacher records describing daily classroom activities were used to operationalize two types of instruction: active learning, which used the labs; and traditional, which used the teaching resources ordinarily available to the teacher. Teacher records indicated that they used less independent work and fewer worksheets, and more collaborative and lab‐based activities, with active‐learning labs compared to traditional instruction. In‐class test data show that students gained significantly more content knowledge and knowledge of process skills using the labs compared to traditional instruction. Questionnaire data revealed that students perceived greater learning gains after completing the labs compared to covering the same content through traditional methods. An independent questionnaire administered to a larger sample of teachers who used the lab‐based curriculum indicated that they perceived changing their behaviors as intended by the student‐centered principles of the labs. The major implication of this study is that active‐learning–based laboratory units designed and developed collaboratively by high school teachers and university faculty, and then used by high school teachers in their classrooms, can lead to increased use of student‐centered instructional practices as well as enhanced content knowledge and process learning for students. © 2007 Wiley Periodicals, Inc.
