Noncognitive predictors of achievement in introductory college chemistry

The purpose of this study was to investigate the predictive relationship between initial student attitudes, admissions test scores, years of high school math taken, and subsequent achievement in introductory college chemistry. Included in this study was a sample of 179 students who began as new freshmen during the same fall semester and took an introductory chemistry course during their first year of college. The results of this study indicated that noncognitive variables were significant predictors of student performance. These findings also indicated that, for some types of academic outcomes, noncognitive variables may be better predictors of achievement than traditional measures such as admissions test scores.     

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.     

Designing for interaction,thinking and academic achievement in a Tanzanian undergraduate chemistry course

Virtual learning environments are used in higher education around the world to promote student learning. However, in many countries it has not yielded the expected effect on student interaction and learning. The purpose of this study was to investigate whether the use of certain pedagogical approaches would promote student interaction, higher-order thinking and achievement. 102 undergraduate students taking an introductory chemistry course at a Tanzanian university participated in the study, and were randomly assigned to three groups. Each group first studied one topic using the control design (non-interactive learning, NIL) to establish a baseline. Then each group studied three further topics using different pedagogical approaches (NIL), discussion forums (medium interactive learning) and podcasts (highly interactive learning). Data included interviews, subject tests, and the content of online discussion forums. All qualitative data were coded, and repeated-measures ANOVA was used to analyze within design and between design effects; student interaction patterns were analyzed using social network analysis. Results show that social interaction, academic achievement and thinking improved progressively over the three topics (iterations) in each design. The changes in instructor pedagogical strategies and the actions of students to bring what they had learned from podcasts to the learning community contributed to the marked improvement. We conclude that effective use of discussion forums in higher education in Tanzania can produce important learning effects (interaction, thinking, and enhanced academic achievement) and is a low-bandwidth strategy, but coupling podcasts with discussion forums may be a powerful way to enhance the effects.     

An Investigation of Effectiveness of Conceptual Change Text-oriented Instruction on Students' Understanding of Solution Concepts

This study investigated the effect of conceptual change text-oriented instruction over traditional instruction on students' understanding of solution concepts (e.g., dissolving, solubility, factors affecting solubility, concentrations of solutions, types of solutions, physical properties of solutions) and their attitudes towards chemistry. The sample of this study consisted of 87 undergraduate students from two classes enrolled in an introductory chemistry course. One of the classes was assigned randomly to the control group, and the other class were assigned randomly to the experimental group. During teaching the topic of solution concepts in the chemistry curriculum, a conceptual change text-oriented instruction was applied in the experimental group whereas traditional instruction was followed in the control group. The results showed that the students in the experimental group performed better with respect to solution concepts. In addition, it has been found that there was no significant difference between the attitudes of students in the experimental and control groups towards chemistry.     

The Impact of Internet Virtual Physics Laboratory Instruction on the Achievement in Physics, Science Process Skills and Computer Attitudes of 10th-Grade Students

The purpose of this study was to investigate and compare the impact of Internet Virtual Physics Laboratory (IVPL) instruction with traditional laboratory instruction in physics academic achievement, performance of science process skills, and computer attitudes of tenth grade students. One-hundred and fifty students from four classes at one private senior high school in Taoyuan Country, Taiwan, R.O.C. were sampled. All four classes contained 75 students who were equally divided into an experimental group and a control group. The pre-test results indicated that the students’ entry-level physics academic achievement, science process skills, and computer attitudes were equal for both groups. On the post-test, the experimental group achieved significantly higher mean scores in physics academic achievement and science process skills. There was no significant difference in computer attitudes between the groups. We concluded that the IVPL had potential to help tenth graders improve their physics academic achievement and science process skills.     

Sharing,Talking, and Learning in the Elementary School Science Classroom: Benefits of Innovative Design and Collaborative Learning in Computer-Integrated Settings

Impact on student achievement of randomly assigned students working individually or collaboratively in mixed- and matched-gender pairs at a computer on predetermined science tasks was investigated. Collaborative dyads shared a computer and screen as each operated an independent keyboard and mouse. A mixed gender control group working individually at their respective computers was used for comparison purposes. A software application was designed to facilitate collaborative work and track the quantity of text written by users and their respective use of time. A final written assessment was conducted to compare the level of academic achievement between the control group and the experimental. A significant difference in academic achievement resulted.

A structured career intervention program for academically challenged students

A study was carried out to test the effects of a 2-week structured intervention program on academically challenged students’ career development. A quasi-experimental study was designed using pre-tests, post-tests, and a control group approach to examine the effects of the intervention program. Data were collected from both the experimental and control groups. The test was carried out on eight schools in the state of Kedah in Malaysia. Eight school counselors were trained to facilitate the assignment to the experimental groups and to collect data. A total number of 335 students with low academic achievement participated in this study. This number included male (43.6 %) and female (56.4 %) students who were aged 15–16 and a half. Modes of measurement used consisted of a career planning inventory (measuring career planning skills), an academic learning motivation scale (measuring attitude toward academic learning), and an academic study skills test (measuring academic study competencies). Analysis was performed using t-tests and the multivariate analysis of variance to examine the differences in the mean scores. The results show that the sample’s career academic score improved significantly from the pre-test to the post-test. A simple regression analysis was also performed to see the effect of the intervention program on the three dependent variables, which revealed that the career intervention program has positive and significant effects on the three variables. However, further studies on the career program for academically challenged students are highly recommended to support the present study.     

Factors Contributing to Achievement in the Study of First Semester College German

This study was undertaken to determine whether a relationship existed between cultural literacy and academic achievement. It was found that among the fifth graders involved in the study there was a significant positive correlation between cultural literacy and academic achievement. In addition, although ethnicity, socioeconomic status, and type of school attended influenced the cultural literacy of the students, the positive relationship between cultural literacy and academic achievement existed among all these subgroups. The article briefly examines reasons behind this relationship.     

Cognitive Style,Gender, Attitude toward Computer‐assisted Learning and Academic Achievement

This paper reports an investigation of cognitive style, gender, attitude toward using computer‐assisted learning (CAL) and academic achievement among university students. A Group Embedded Figures Test was used to assess students’ cognitive style and a questionnaire was used for the evaluation of students’ attitude toward CAL. The results revealed that students have positive attitudes toward CAL but they were not prepared to rely entirely on CAL. A 2 x 2 ANOVA was used to investigate the effect of cognitive style and gender on the attitude toward CAL. The results revealed that male students preferred using CAL significantly more than females and field dependent students were more prepared to rely entirely on CAL than field independent students. On the other hand, there was a significant difference between males and females in their achievement scores in favour of the male group. But there was no difference between field dependence and field independence groups in their achievement. The results also revealed no significant relationship between students’ attitudes toward CAL and their achievement in these courses.     

Learning Microbiology with Computer Simulations: students’ academic achievement by method and gender

Tenth grade students studied the topic of ‘The growth curve of microorganisms’, which included a computer‐assisted learning (CAL) simulation episode. The CAL episode enabled students to simulate experiments which investigated the simultaneous impact of three independent variables upon the growth curve of microorganisms (temperature, nutrient concentration and the initial number of individuals from which to start a population growth). Two classes (n = 82 students) formed the experimental group and were instructed in a combination of classroom‐laboratory work with CAL. The control group included three classes (n = 99 students) who were taught the topic in the classroom‐laboratory work setting only. Five teachers taught the five classes, three periods weekly and the study lasted 4 weeks. The students’ previous knowledge in the topic to be learned and their academic achievement were assessed with pre‐ and post‐tests, respectively. The data for each lest were treated with a two‐way analysis of variance. The results showed that the two study groups did not differ in their previous knowledge and no significant differences were found by gender within and between the groups. The post‐test results on academic achievement indicated that students in the experimental group achieved significantly higher means scores than the control group. No significant gender differences on academic achievement were found within each group. The results affirm that: (a) computer simulations, in which three variables are manipulated simultaneously in one experiment, can be integrated as short episodes in the existing biology curricula; (b) high school students can perform computer simulations which require the skills of simultaneous manipulations of three variables in one experiment, problem solving and decision making; (c) girls and boys in the experimental group exhibited these skills at a similar academic level of achievement.     

Longitudinal analysis of time, engagement, and achievement in at-risk versus non-risk students

This longitudinal study investigated the effects of time spent in academic instruction and time engaged on elementary students' academic achievement gains. Three groups were compared over grades as follows: (a) an at-risk experimental group of low-socioeconomic status (SES) students for whom teachers implemented classwide peer tutoring (CWPT) beginning with the second semester of first grade continuing through Grade 3; (b) an equivalent at-risk control group; and (c) a non-risk comparison group of students of average- to high-SES. In both the control and comparison groups, teachers employed conventional instructional practices over Grades 1 through 3. Results indicated significant group differences in the time spent in academic instruction, engagement, and gains on the subtests of the Metropolitan Achievement Test that favored the experimental and comparison groups over the control group. Implications include the effectiveness of CWPT for at-risk students and the continuing vulnerability of at-risk students whose daily instructional programs provide less instructional time and foster lower levels of active academic engagement.     

Comparison of computer-assisted instruction and print drill performance: A research note

A comparison of the performance of two groups of third-grade students practicing division problems is used to assess the effect of a commercial computer-assisted instruction (CAI) drill program on learning. The progress of the experimental group, who used the computer drill program, is compared with a similar group of students using a conventional print drill method. The data demonstrate that after five weeks of practice, no significant differences existed in the achievement level of either the experimental group or the control group. The findings further suggest that use of computer drill materials may be no more effective than print drill materials for assisting third-grade students to achieve proficiency level in learning division of whole numbers.     

Changes in race and sex stereotype threat among diverse STEM students: Relation to grades and retention in the majors

In laboratory studies, induced stereotype threat shows negative effects on academic performance and learning. Is the relation between stereotype threat and grades robust in naturalistic settings, specifically in introductory STEM courses? We gathered data on two new measures we term race and sex stereotype bias, which were administered four times over the course of introductory chemistry and biology courses for STEM majors (N = 1358). Patterns of growth for all stereotype bias measures showed a discontinuous pattern, with increases during each semester (fall and spring) and decreases between semesters. For all stereotype bias measures, sophomores scored significantly higher than freshmen, and juniors scored in between. For the sex stereotype bias measure, females scored significantly higher than males. There were no race or sex differences on slopes of growth; though groups began at different levels, all grew at the same rate. There was little relation between grades and stereotype bias when analyzed by race; Asian students showed the largest number of significant – albeit small – correlations (3) and Black students the fewest (none). Correlations between grades and sex stereotype bias were significant and negative – but small – only for males. Results support a point made by Steele in 1997 but neglected since then; stereotype threat may affect only a small sub-portion within stereotyped groups. We argue that variables other than stereotype threat might be better targets for research attempting to explain gaps in STEM achievement and retention.     

Usefulness of concept maps in college chemistry laboratories: Students' perceptions and effects on achievement

The problem addressed by this study is that first-year college chemistry students learn little of the conceptual material associated with chemistry experiments they perform. The thesis of this research is that the construction of prelab and postlab concept maps help students understand the concepts involved in the experiments they perform. The study was conducted using 32 non–science majors enrolled in a first-year chemistry course. The experimental group constructed prelab and postlab concept maps, while the control group wrote essays explaining the conceptual chemistry of the four experiments used in this study. Both groups took 25-item achievement tests 1 week after each experiment. Prelab and postlab concept maps were scored and evaluated for significant differences. Five students were interviewed to investigate their perceptions regarding the usefulness of concept maps in chemistry laboratories. No significant differences were found between treatment groups with respect to students' conceptual understanding as determined by the multiple choice achievement tests. Students responded very positively toward the use of concepts maps in the laboratory. They felt strongly that constructing prelab and postlab concept maps helped them understand the conceptual chemistry of the experiments. © 1998 John Wiley & Sons, Inc.

THE EFFECTS OF IMMEDIATE FEEDBACK ON RETENTION IN AN ACADEMIC SETTING

The present study was to determine the effects of immediate feedback on retention. The sample included 186 students enrolled in eight sections of an introductory psychology course. Four sections were randomly assigned to the experiment group, and four were designated the control group. Experimental treatment was accomplished through the use of a self‐scoring test‐answer sheet. A quasi‐experimental, nonequivalent control group research design was used to allow testing of a null hypothesis. Analysis of variance revealed no significant difference in retention rates between the experimental and control groups.     

Learning to learn at university. The effects of an instrumental subject on learning strategies and academic achievement / Aprender a aprender en la universidad. Efectos de una materia instrumental sobre las estrategias de aprendizaje y el rendimiento académico

Self-regulated learning is very important at university, since students must manage the strategies and abilities necessary to be autonomous and effective in their learning. The aim of this study was to analyse the effects of a course designed for this purpose on learning strategies and students’ achievement of first-year university students. A quasi-experimental pre-test/post-test design was used, with an experimental group and a control group, applying measurement instruments before starting and after finishing the course. The learning process was analysed on this course, with students being trained in the use of relevant learning strategies — metacognitive strategies, strategies for processing and using information and affective and motivational strategies. The sample consisted of 47 students, 23 of them belonging to the experimental group and 24 of them to the control group, from various degrees at the University of Valencia. The results confirmed significant improvements in the learning strategy scores of the experimental group compared to the control group. There was also an improvement in academic achievement, but in this case the differences were not statistically significant.     

Effects of integrated video media on student achievement and attitudes in high school chemistry

This study explored the effects of an integrated video media curriculum enhancement on students' achievement and attitudes in a first-year general high school chemistry course within a multiculturally diverse metropolitan school district. Through the use of a treatment-control experimental design, approximately 450 students in Grades 9–12 were sampled on measures of chemistry achievement and attitude over the period of 1 academic year. The results revealed significantly higher achievement scores on standardized measures of achievement as well as on microunit researcher-designed, criterion-referenced quizzes for the treatment students who experienced a general chemistry course enhanced with an integrated use of a structured chemistry video series. Correlation of student achievement with logical thinking ability revealed that students with high levels of logical thinking ability benefited most from the video-enhanced curriculum. Treatment students also scored significantly higher than control students on the chemistry attitude instrument. These results along with qualitative supportive evidence suggest that this integrated video media curriculum intervention can positively affect student chemistry achievement and attitude across ability levels and across a diverse multicultural population. Furthermore, the data suggest that educational science video media in general, and the World of Chemistry video series in particular, are instructional tools that can be used effectively to bring the often abstract, distant worlds of science into close focus and within the personal meaningful realm of each individual student. © 1997 John Wiley & Sons, Inc.

The effects of the cooperative learning method supported by multiple intelligence theory on Turkish elementary students’ mathematics achievement

In the present experimental study, the effects of the cooperative learning method supported by multiple intelligence theory (CLMI) on elementary school fourth grade students’ academic achievement and retention towards the mathematics course were investigated. The participants of the study were 150 students who were divided into two experimental (used CLMI) and two control groups (used traditional method). “Mathematics Achievement Test,” “Teele Inventory for Multiple Intelligences” and “Personal Information Form” were used as the measurement instruments of the study. The findings of this research have indicated that CLMI has a more significant effect on academic achievement than the traditional method. Yet, regarding the retention scores, CLMI has not significant effect on retention.     

Investigating the Effectiveness of Desktop Virtual Reality for Teaching and Learning of Electrical/Electronics Technology in Universities

Abstract

This study compared efficiency of desktop virtual reality with a conventional classroom learning practice for the teaching and learning of electrical/electronics technology. This was measured through academic achievement, learning interest, and engagement. A quasi-experimental design was employed for this study. Four universities were used for the study. The students were within the ages of 17 to 24?years. Students were assigned to either an experimental or comparison group based on intact classes. A total of 149 students participated in this experiment; however, only 142 samples could be analyzed. Seven samples were not analyzed due to incomplete instruments answered and absenteeism. Seventy-four students were in the virtual reality group while 68 students were in the non virtual reality group. The sample was 78.52% and 21.48% in males and females, respectively. Analysis of covariance was used to test three formulated hypotheses on effects of desktop virtual reality on the learning effectiveness of the students. There was a significant difference in academic achievement, learning interest, and learning engagement between the two groups. It was established that desktop virtual reality positively affected students’ academic achievement, learning interest, and engagement of students in electronics technology. It was suggested that virtual reality should be adopted to augment laboratory practices for the teaching and learning of electrical/electronics technology in Nigerian universities.
