Imagery/Concreteness Attributes of Advance Organizers

The purpose of this study was to examine the attributes of prose passages used in advance organizer studies on an imagery-concreteness scale. Phase I demonstrated significant differences in ratings between organizer, historical, and learning passages using a semantic differential type instrument. A principal components factor analysis of the scale provided evidence of a stable factor structure for the instrument across the three passages. Phase II demonstrated significant differences in retention for the organizer-learning passage combination but no differences when the three passages were examined alone. Results are discussed on the basis of Paivio’s two-process theory, and questions are raised about the role of advance organizers in learning and retention.     

Can images provide contextual support for prose?

This study sought to determine whether contextual organizers presented before prose passages can improve learning and retention among students who have no prior knowledge of the subject. The researchers used two types of organizers — an image and its verbal equivalent. Students who were provided the organizers scored better than control students on tests given two weeks later, but the predicted advantage of images over verbal learning adjuncts did not appear.     

Adding interactive graphic organizers to a whole-class slideshow lesson

This study examines the effects of including interactive graphic organizers into a whole-class PowerPoint lesson as an instructional approach intended to improve student engagement and generative learning in schools. A software application was developed and integrated into PowerPoint that makes it possible for the instructor to fill in empty graphic organizers during PowerPoint projection mode. The participants were 152 fourth-grade students selected from three schools that were grouped in four classrooms. Each classroom was divided in two groups—graphic organizer and content-based. The graphic organizer group was taught using an 11-slide PowerPoint presentation on a social study topic that included two empty graphic organizers plus two additional slides explaining how to make a comparison. The content-based group was taught using the same presentation but without these additional slides plus a set of questions students had to answer as a class activity. The lessons were recorded and the verbal statements between instructor and students examined using the Flanders Interaction Analysis System. Results indicated significant differences in how instructors and students interacted in each group, including more questions asked by teachers (d?=?1.99) and more students participating in the classroom discussion in the graphic organizer group (d?=?1.76). Learning outcomes showed that the graphic organizer group outperformed the content-based group on a memory test (d?=?.45) and a comprehension test (d?=?.44). These results encourage the use of graphic organizers as an instructional approach, and are consistent with a generative theory of learning.     

A computer-based spatial learning strategy approach that improves reading comprehension and writing

This article explores the effectiveness of a computer-based spatial learning strategy approach for improving reading comprehension and writing. In reading comprehension, students received scaffolded practice in translating passages into graphic organizers. In writing, students received scaffolded practice in planning to write by filling in graphic organizers and in translating them into passages. Based on a cluster-randomized sampling process, 2,468 students distributed in 12 schools and 69 classrooms participated in the study. Schools were randomly assigned to the computer-based instruction (CBI) group or traditional instruction (TI) group. Teachers assigned to the CBI treatment integrated the applications into the language arts curriculum during one school semester. A standardized test was used to measure reading comprehension and writing. The data were analyzed through a statistical multilevel model. The findings showed that students in the CBI group improved their reading and writing skills significantly more than students under TI—yielding an effect size d = 0.30.     

The comprehension of first and second-language prose

How does national culture interact with second-language reading comprehension? This study investigated the effect of cultural medium of presentation, language, and sequence of cultural/foreign and first-language/second-language presentation on the literal and interpretative comprehension of Form I (seventh grade) bilingual Nigerian students. Data were analysed using ANOVA. Previous studies concerning schema theories were upheld in that the present results for Experiment 1 revealed significantly superior scores for culturally related English language text when compared with scores for foreign-based passages written in English. The data from Experiment 2 also revealed similar results when the subjects were presented with the same Experiment 1 foreign-based passages written in English and with translations of these English passages to the mother tongue. In spite of sequencing, scores were higher for the first-language passages. For both experiments, scores were higher at the literal level and sequencing was found to have little effect in enhancing comprehension of culturally unfamiliar material.     

Graphic organizers and their effects on the reading comprehension of students with LD: a synthesis of research

Previous research studies examining the effects of graphic organizers on reading comprehension for students with learning disabilities (LD) are reviewed. An extensive search of the professional literature between 1963 and June 2001 yielded a total of 21 group design intervention studies that met the criteria for inclusion in the synthesis. Using graphic organizers (i.e., semantic organizers, framed outlines, cognitive maps with and without a mnemonic) was associated with improved reading comprehension overall for students with LD. Compared to standardized reading measures, researcher-developed comprehension measures were associated with higher effect sizes. Initial gains demonstrated when using graphic organizers were not revealed during later comprehension tasks or on new comprehension tasks.     

A study of the use of “invitations to enquiry” and student attitude

This study was designed to isolate the attitude of high ability ninth grade BSCS students toward instruction utilizing “Invitations to Enquiry.” Both control and experimental groups received similar instruction with the addition of twenty “Invitations” to the experimental classes over an eight week period. No significant differences in attitudinal scores as measured by Remmer's A Scale to Measure Attitude Toward Any School Subject was found when the poststudy scores were adjusted for prestudy attitude, IQ and mid-study attitude or when the attitude at the end of four weeks of the study was adjusted using prestudy attitude and IQ.     

The effectiveness of graphic organizers for three classifications of secondary students in content area classes.

Previous research concerning the graphic or visual display of information with academically handicapped students has not addressed the instructional conditions that exist in mainstream settings. This article investigates the effectiveness of graphic organizers for three classifications of secondary students enrolled in content area classes: students with learning disabilities, remedial students, and students in regular education. The results of three separate experiments indicated that graphic organizers, whether teacher-directed, student-directed with text references, or student-directed with clues, produced significantly higher performance than self-study for each group of students. Several practical issues involving the use of graphic organizers with heterogeneous groups of secondary students are discussed.     

The Learning Environment of High School Students in Chemistry and Biology Laboratories

In this article a comparison of students’ perceptions of laboratory classes in chemistry and biology is presented. By using the Science Laboratory Environment Inventory (SLEI), pronounced and significant differences between chemistry and biology laboratory environments were found on two of the subscales: ‘Integration’ that describes the extent to which its laboratory activities are integrated with non‐laboratory and classroom learning and ‘Open‐endedness’, a subscale that measures the extent to which the laboratory emphasises an open‐ended, divergent, and an individualised approach to experimentation. It is suggested that the SLEI can be considered as a sensitive tool to measure students’ perceptions of their learning environment in different subject matters during the laboratory work. In this study the SLEI was also used to compare students’ actual and preferred learning environments and to explore gender differences regarding this issue.     

Effects of graphic organizers in online discussions: comparison between instructor-provided and student-generated

The current experimental study examined the effects of graphic organizers in a collaborative learning context where students constructed knowledge during online discussions. As the results could vary depending on how students interacted with the graphic organizers, this study compared two different approaches: instructor-provided versus student-generated graphic organizers. Thus, the purpose of this study was to investigate the effects of receiving or generating graphic organizers on students’ engagement in online discussions. Thirty-six graduate students enrolled in an online graduate course participated in the study. While analyzing an instructional design case, students were asked to discuss design issues in a randomly assigned group. There were three conditions: control condition without graphic organizers, instructor-provided, and student-generated graphic organizers. Major findings revealed that both generating and receiving graphic organizers facilitated students’ higher levels of cognitive engagement, and encouraged students to consider alternative views during the discussions. Without the graphic organizer, students tended to simply summarize previous messages or raise new issues rather than elaborating on previous topics. There was a significant finding regarding the ways of interacting graphic organizers. Students discussed more topics when they were given instructor’s graphic organizers rather than when they were asked to generate them.     

Teaching Criminal Justice Online: Current Status and Important Considerations

The most significant change to impact the pedagogy of criminal justice students in recent years has been the development of online classes. Online coursework is now a commonly accepted method of accessing criminal justice students and the sustained growth in online classes is expected to continue in the future. However, there is currently a lack of research that focuses on online classes in criminal justice. In response, we present and assess the modest literature regarding criminal justice online classes and highlight important themes. This leads into a presentation of important considerations along the following pedagogical continuum: Planning the online course (i.e. asynchronous timing, technological developments), implementing the online course (i.e. maintaining an online presence, managing student interactions and expectations), and identifying effective means to measure learning outcomes (i.e. measuring success, quality matters). Policy implications for online coursework that are likely to impact future criminal justice educational practices are then discussed.     

Cooperative learning and group educational modules: Effects on cognitive achievement of high school biology students

The purpose of this study was to examine the effects of cooperative learning and Group Educational Modules (GEM) on the achievement of high school biology students. GEM materials are self-instructional packets designed for use with groups of biology students. Cooperative learning is a classroom learning environment in which students work in small, mixed-ability groups toward a common goal. A 2 × 2 factorial design was used in this study. The independent variables considered included (1) participation of students in the GEM project, and (2) use of cooperative learning techniques including heterogeneous grouping and group incentives. The dependent variables for all treatment groups were scores on the instrument developed for this study. A total of 11 teachers with 36 classes and 715 students were included in this study. All teachers involved covered the same general subject matter during the study period. An analysis of covariance (ANCOVA) was used as the data analysis procedure. Significant differences were found in the achievement of students using GEM materials and those using traditional instructional approaches. The use of cooperative learning also produced significant differences when compared to traditional classroom structures.     

The Effects of Learning Strategy Instruction on Achievement, Attitude, and Achievement Motivation in a Physics Course

This article reports on the influence of learning strategy instruction on student teachers’ physics achievement, attitude towards physics, and achievement motivation. A pre-test/post-test quasi-experimental design with matching control group was used in the study. Two groups of student teachers (n = 75) who were enrolled in an introductory physics course participated in the study. In the experimental group, questioning, summarizing, and graphic organizers were taught. The control group did not receive any presentation on strategy learning. Data were collected via the pre- and post-administration of the Physics Course Achievement Test, the Scale of Attitudes towards Physics, and the Achievement Motivation Scale. Univariate and multivariate analyses of variance on the data revealed no significant differences in the attitude and achievement motivation between the strategy and control groups. However, the strategy group students were observed to have a tendency of more positive attitude and motivation than the control group students. Results also showed that explicit learning strategy instruction was more effective than traditional instruction in improving physics achievement of the participating students. The implications of these results for physics education are discussed.     

EFFECTIVENESS OF USING GAMES IN TERTIARY-LEVEL MATHEMATICS CLASSROOMS

The primary focus of this study was to investigate the effectiveness of games when used in tertiary-level mathematics classes in the United Arab Emirates. Our study incorporated a mixed-method approach that involved surveys (to assess students?? perceptions of the learning environment and attitudes towards mathematics), interviews, observations of classes and narrative stories. A sample of 90 students from 3 tertiary-level institutions in Abu Dhabi participated in the study. In-depth qualitative data provided information about the introduction and use of games in mathematics. A narrative, based on classroom observations of students playing Jeopardy!-type mathematics games, provided insights into games in action in the classrooms. The data were analysed to examine students?? interactions during the games and to triangulate, clarify and explain students?? responses to the learning environment and attitude questionnaires. To examine pre?Cpost differences in students perceptions of the learning environment and their attitudes, 2 questionnaires were administered to students before and after the introduction of games. Pre?Cpost differences for 3 of the 6 learning environment scales (Teacher Support, Involvement, Personal Relevance) and both attitude scales (Enjoyment of Mathematics Lessons and Academic Efficacy scales) were statistically significant. Information obtained from interviews with students and teachers were used to explain the pre?Cpost differences.     

Effect of language of instruction on physics achievement

This study investigated the relationship between physics achievement and language of instruction in a situation where instruction was in the second language of both students and teachers. One hundred and seventy-six grade ten physics students (first language was Chinese) were selected from four classes of two secondary schools in Hong Kong. For three months (with four lessons per week), two classes of students learned the content material (light and sound) in Chinese and two classes learned the material in English. Group differences were controlled by using individual aptitude scores as covariates in the analysis. There were no differences in achievement, students' motivation, and effort spent in physics in that controlled teaching period. This was probably because the Anglo-Chinese group was sufficiently proficient in English so they did not encounter additional difficulty in learning physics when compared with the Chinese group.     

Impact of multimedia on students’ perceptions of the learning environment in mathematics classrooms

We investigated (1) whether the learning environment perceptions of students in classes frequently exposed to multimedia differed from those of students in classes that were not, (2) whether exposure to multimedia was differentially effective for males and females and (3) relationships between students’ perceptions of the learning environment and student engagement in classes that were exposed to multimedia. The sample involved 365 high-school students in 16 classes, nine that were frequently exposed to multimedia and seven that were not. Two instruments were administered to students: one to assess students’ perceptions of the learning environment and another to assess student engagement. There were statistically significant differences between the two groups for all of the learning environment scales, as well as statistically significant interactions between exposure to multimedia and sex for three learning environment scales (Involvement, Task Orientation and Equity). Finally, the learning environment in mathematics classes that involved multimedia was related to student engagement. These results offer potentially important insights into how student exposure to multimedia could promote more positive learning environments and improve student engagement in mathematics.     

False memory for orthographically versus semantically similar words in adolescents with dyslexia: a fuzzy-trace theory perspective

The presented research was conducted in order to investigate the connections between developmental dyslexia and the functioning of verbatim and gist memory traces—assumed in the fuzzy-trace theory. The participants were 71 high school students (33 with dyslexia and 38 without learning difficulties). The modified procedure and multinomial model of Stahl and Klauer (simplified conjoint recognition model) was used to collect and analyze data. Results showed statistically significant differences in four of the model parameters: (a) the probability of verbatim trace recollection upon presentation of orthographically similar stimulus was higher in the control than dyslexia group, (b) the probability of verbatim trace recollection upon presentation of semantically similar stimulus was higher in the control than dyslexia group, (c) the probability of gist trace retrieval upon presentation of semantically similar stimulus was higher in the dyslexia than control group, and (d) the probability of gist trace retrieval upon target stimulus presentation (in the semantic condition) was higher in the control than dyslexia group. The obtained results suggest differences of memory functioning in terms of verbatim and gist trace retrieval between people with and without dyslexia on specific, elementary cognitive processes postulated by the fuzzy-trace theory. These can indicate new approaches in the education of persons with developmental dyslexia, focused on specific impairments and the strengths of their memory functioning.     

Optimal presentation of graphic organizers and text: A case for large bites?

In three experiments, we investigated the optimal presentation of graphic organizers (GOs) and text by having undergraduates read a chapter-length text in its entirety, a few pages at a time, or a few sentences at a time, before or after viewing seven GOs in their entirety (large bites), one at a time (small bites), or one cell at a time (animated). Large bites were better than small bites for learning concept relations and applying that knowledge, and for recalling macropropositions when the GOs were presented before text. Animated GOs offered no advantages over the large-bites GOs at first presentation and considerably extended total study time. Presenting several GOs first, followed by the entire text, appears to be optimal in directing students’ attention to across-chapter relations in text.     

Creative Problem Solving in Teacher Education

Abstract

Colleges typically group students homogeneously in classes by means of both admission requirements and course prerequisites, but when professors form cooperative learning groups within classes they generally use heterogeneous grouping. Authors compared heterogeneously and homogeneously grouped cooperative learning groups in six paired classes, taught by the same professor using matching syllabi and assignments. Overall, homogeneously grouped students (who were grouped based on achievement on the first test given in the course) significantly outperformed heterogeneously grouped students on the final examination. High- or average-achieving students particularly benefited from homogenous grouping. Low achievers did equally well in either type of group.     

Matching/mismatching revisited: an empirical study of learning and teaching styles

This paper presents results of a research project that explored the relationship between matching and mismatching instructional presentation style (breadth-first and depth-first) with students' cognitive style (field-dependence/-independence) in a computer-based learning environment. 73 postgraduate students were asked to create Web pages using HTML, using instructional materials that were either matched or mismatched with their cognitive styles. Significant differences in performance on a multiple choice test of conceptual knowledge were found for students learning in matched and mismatched conditions. Performance in matched conditions was significantly superior to that in mismatched conditions. However, significant effects were found for gender, matching mainly affecting male students. Performance on a practical test of Web page creation was not linked to matching or mismatching, but was linked to an interaction between gender and instructional presentation style. The findings provide support for the notion that matching and mismatching can have significant effects on learning outcomes. The paper concludes with suggestions for further research.
