The effects of new science curricula on student performance

This study summarizes the results of a quantitative synthesis of the retrievable primary research dealing with the effects of new science curricula on student performance. This study synthesizes the results of 105 experimental studies involving more than 45,000 students and utilizes the quantitative synthesis perspective to research integration known as meta-analysis (Glass, 1976). A total of 27 different new science curricula involving one or more measures of student performance are included in this meta-analysis. Data were collected for 18 a priori selected student performance measures. The results of this meta-analysis reveal definite positive patterns of student performance in new science curricula. Across all new science curricula analyzed, students exposed to new science curricula performed better than students in traditional courses in general achievement, analytic skills, process skills, and related skills (reading, mathematics, social studies and communication), as well as developing a more positive attitude toward science. On a composite basis, the average student in new science curricula exceeded the performance of 63% of the students in traditional science courses.     

The impact of science curricula on student views about the nature of science

This review of the literature focused on three decades of research related to precollege student understandings about the nature of science. Various interpretations of what aspects characterize the nature of science were examined, revealing an agreement among scientists, science educators, and those involved in policy-making arenas that the nature of science is multifaceted and an important component of scientific literacy. A summary of the research regarding the adequacies of student conceptions about the nature of science revealed inconsistent results. Although the majority of studies show that student understandings are less than desirable, there is research that indicates that student conceptions are acceptable. Research on the impact of instructional materials and techniques on student understandings was also reviewed. The effects of language in science instruction, the content emphasis of instructional materials, integrated science curricula, and instruction in general were curricular variables found to have a negative impact on student understandings about the nature of science. Empirical evidence about the success of innovative instructional materials and techniques designed to facilitate more adequate understandings of the nature of science is needed.     

The effects of passive and active learning on student preference and performance in an undergraduate basic science course

Active learning is based on self-directed and autonomous teaching methods, whereas passive learning is grounded in instructor taught lectures. An animal physiology course was studied over a two-year period (Year 1, n = 42 students; Year 2, n = 30 students) to determine the effects of student-led seminar (andragogical) and lecture (pedagogical) teaching methods on students' retention of information and performance. For each year of the study, the course was divided into two time periods. The first half was dedicated to instructor-led lectures, followed by a control survey in which the students rated the efficiency of pedagogical learning on a five-point Likert scale from one (strongly disagree) to five (strongly agree). During the second period, students engaged in andragogical learning via peer-led seminars. An experimental survey was then administered to students using the same scale as above to determine students' preferred teaching method. Raw examination scores and survey results from both halves of the course were statistically analyzed by ANOVA with Newman-Keuls multiple comparison test. By the end of the study, student preference for peer-led seminars increased [mean ± SD: (2.47 ± 0.94)/(4.03 ± 1.36), P < 0.04], and examination scores significantly increased [mean ± SD: (73.91% ± 13.18)/(85.77 ± 5.22), P < 0.001]. A majority of students (68.8%) preferred a method that contained peer-led seminars and instructor-led lectures. These results may indicate that integration of active and passive learning into undergraduate courses may have greater benefit in terms of student preference and performance than either method alone.

The relationship of student characteristics and student performance in science as viewed by meta-analysis research

Relationships of student characteristics to student performance and attitudes were explored by meta-analysis for studies conducted in kindergarten through twelfth grade since 1960. Six student characteristics (general ability, language ability, mathematics ability, socio-economic status, gender, and race) were selected for inclusion in this investigation based on their frequency of use in the literature. Studies in which these student characteristics were associated with student science performance or science attitudes were included in this investigation. Associations of ability and socio-economic status with science performance and attitudes were summarized by correlational analysis. An effect size measure was used to summarize associations of gender and race with science performance and attitudes.

The investigation of school effects on student achievement in science: A multilevel analysis of educational data

The Second International Science Study provides a large Australian data base for the purpose of secondary analyses. This data base consists of a large number of student and school level variables which were examined with reference to the students nested within the schools. Multilevel analysis involves the use of the hierarchical linear model to adequately compensate for variability between-schools, as well as within-schools. The role of the school organization and effects such as the average student ability and average social factors were found to substantially influence student achievement in science. These school effects were also found to influence boys and girls differently with respect to their science achievement as measured by the tests in this study. Specializations: large scale data analysis, gender differences, socioeconomic factors, epidemiology.     

GCSE exam stress: student perceptions of the effects on wellbeing and performance

ABSTRACT

In the UK education system, an ‘audit culture’ has led to pressures being placed on students to achieve high grades in their GCSEs. It has been suggested that schools are required to achieve good academic results and look after their students’ wellbeing, causing a conflict in relation to public examinations, such as GCSEs. School staff support both performance and wellbeing by preparing students for exams. However, research suggests that there is a danger that many underperform, or are negatively affected (emotionally) by exam stress, or both. This paper describes a research project within the UK. The aims of which were to explore the views of students who had recently taken GCSE exams, to gain an understanding of how they felt their GCSE experiences affected their wellbeing and performance, to find out what factors contributed to or alleviated their levels of exam stress, and whether theories relating to exam stress such as Achievement Goal Theory could be used to explain the individual differences in levels of exam stress. Findings and conclusions provided ways to improve the support for students during their GCSEs, improving academic performance and wellbeing.     

A model of MBA student performance

A number of regression studies have attempted to predict success in an MBA program. The current study extends the work of previous investigations by proposing a model that incorporates a number of terms which represent interaction of undergraduate grade point average with undergraduate institution and undergraduate major. The resulting model has a significantly largerR ² value then previously reported studies. The largeR ² value is attributed to a more complete model and a careful scrutinizing of the data employed in model construction.     

Teacher effects on student attrition and performance in mass-market tertiary education

Tertiary education is now accessible even to those who appear unlikely ex ante to succeed in jobs requiring post-high school education. Institutions that have broadened access to their programs must rely on two things to protect the quality of the degrees they award: selection mechanisms operating during students’ tenure, and effective teaching. This paper explores the relative strength of these two forces in a broad-spectrum, first-year undergraduate course. Using detailed data from the University of South Australia on student background, tutors, performance, and enrollment across 15 weeks in a first-year core course, I explore the extent to which teachers impact upon the success of their students directly (through effective teaching) and indirectly (through facilitating the dropping out of more poorly-prepared students). Results indicate that teachers vary widely in their influence on attrition and performance, and that none is robustly effective in facilitating both the disproportionate out-selection of students with poor initial preparation, and the disproportionate achievement of this group. Performance at neither of these tasks is predictable based on teachers’ formal university affiliation.
