Developing a Scale to Measure Students’ Attitudes toward Chemistry Lessons

Students’ attitudes toward chemistry lessons in school are important dependent variables in curriculum evaluation. Although a variety of instruments have been developed by researchers to evaluate student attitudes, they are plagued with problems such as the lack of theoretical rationale and of empirical evidence to support the construct validity of data. This paper describes a study of students’ attitudes toward chemistry lessons in Hong Kong secondary schools. One of the scales in the Test of Science‐Related Attitudes developed by Fraser was modified to form an Attitude Toward Chemistry Lessons Scale (ATCLS). The construction of the ATCLS was based on a theoretical model with four dimensions: liking for chemistry theory lessons, liking for chemistry laboratory work, evaluative beliefs about school chemistry, and behavioural tendencies to learn chemistry. The arguments for inclusion of these four dimensions are presented. The final version of ATCLS was administered to 954 students. The results of confirmatory factor analysis indicated that there was a good fit between the hypothesised model and the observed data.     

Student Perceptions of Chemistry Laboratory Learning Environments, Student–Teacher Interactions and Attitudes in Secondary School Gifted Education Classes in Singapore

This study investigated the chemistry laboratory classroom environment, teacher–student interactions and student attitudes towards chemistry among 497 gifted and non-gifted secondary-school students in Singapore. The data were collected using the 35-item Chemistry Laboratory Environment Inventory (CLEI), the 48-item Questionnaire on Teacher Interaction (QTI) and the 30-item Questionnaire on Chemistry-Related Attitudes (QOCRA). Results supported the validity and reliability of the CLEI and QTI for this sample. Stream (gifted versus non-gifted) and gender differences were found in actual and preferred chemistry laboratory classroom environments and teacher–student interactions. Some statistically significant associations of modest magnitude were found between students' attitudes towards chemistry and both the laboratory classroom environment and the interpersonal behaviour of chemistry teachers. Suggestions for improving chemistry laboratory classroom environments and the teacher–student interactions for gifted students are provided.     

The Use of Online Modules and the Effect on Student Outcomes in a High School Chemistry Class

The purpose of the study was to review the efficacy of online chemistry simulations in a high school chemistry class and provide discussion of the factors that may affect student learning. The sample consisted of 351 high school students exposed to online simulations. Researchers administered a pretest, intermediate test and posttest to measure chemistry content knowledge acquired during the use of online chemistry laboratory simulations. The authors also analyzed student journal entries as an attitudinal measure of chemistry during the simulation experience. The four analyses conducted were Repeated Time Measures Analysis of Variance, a three-way Analysis of Variance, Logistic Regression and Multiple Analysis of Variance. Each of these analyses provides for a slightly different aspect of factors regarding student attitudes and outcomes. Results indicate that there is a statistically significant main effect across grouping type (experimental versus control, p = 0.042, α = 0.05). Analysis of student journal entries suggests that attitudinal factors may affect student outcomes concerning the use of online supplemental instruction. Implications for this study show that the use of online simulations promotes increased understanding of chemistry content through open-ended and interactive questioning.     

Effects of ‘Environmental Chemistry’ Elective Course Via Technology-Embedded Scientific Inquiry Model on Some Variables

The purpose of this study is to examine the effects of ‘environmental chemistry’ elective course via Technology-Embedded Scientific Inquiry (TESI) model on senior science student teachers’ (SSSTs) conceptions of environmental chemistry concepts/issues, attitudes toward chemistry, and technological pedagogical content knowledge (TPACK) levels. Within one group pre-test–post-test design, the study was conducted with 117 SSSTs (68 females and 49 males—aged 21–23 years) enrolled in an ‘environmental chemistry’ elective course in the spring semester of 2011–2012 academic-years. Instruments for data collection comprised of Environmental Chemistry Conceptual Understanding Questionnaire, TPACK survey, and Chemistry Attitudes and Experiences Questionnaire. Significant increases in the SSSTs’ conceptions of environmental chemistry concepts/issues, attitudes toward chemistry, and TPACK levels are attributed to the SSSTs learning how to use the innovative technologies in the contexts of the ‘environmental chemistry’ elective course and teaching practicum. The study implies that the TESI model may serve a useful purpose in experimental science courses that use the innovative technologies. However, to generalize feasibility of the TESI model, it should be evaluated with SSSTs in diverse learning contexts.     

What college chemistry instructors and high school chemistry teachers perceive as important for incoming college students

Professors of college chemistry were asked to rank various examples of traditional chemistry knowledge and skills as to their importance for incoming students to possess. A pilot study revealed that the items—all selected from one edition of the American Chemical Society-National Science Teachers Association (ACS-NSTA) Chemistry Achievement Examination—represented attributes viewed as relatively unimportant. The professors then identified 29 personal traits they considered more important for incoming students to possess. Subsequently, these items, knowledge, skill, and personal attributes, were included in a three-part assessment instrument. The instrument was administered to 69 college chemistry professors selected at random and to 37 high school chemistry teachers. The results reveal that the college professors universally identified student personal attributes as significantly more important for incoming students to possess over specific knowledge and skills included in the ACS-NSTA Achievement Examination. Chemistry professors do not find items commonly used to assess success in high school chemistry as important attributes for incoming students to possess. Conversely, high school chemistry teachers regard the knowledge and skill items to be more important for college preparation than personal attributes.     

Students' thinking in a chemistry laboratory

Despite the almost mandatory inclusion of a laboratory component in the school curriculum very little has been reported about the effects of laboratory instruction upon student learning and attitudes. The present study was undertaken to investigate the thinking of students in a chemistry laboratory. An interpretive research method was adopted in collecting and analysing data gathered from observations, general interviews and stimulated recall interviews. Four high school students were studied during their participation in a week-long university summer school program. This study reports how the four students responded differently to the same laboratory experience. Specializations: chemistry and biochemistry education, thinking in science and industry. Specializations: science education, teacher learning and preparation, teaching thinking.

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.

Embedded Mathematics in Chemistry: A Case Study of Students’ Attitudes and Mastery

There are many factors that shape students’ attitudes toward science, technology, engineering and mathematics. This exploratory study of high school students examined the effect of enriching chemistry with math on chemistry students’ attitudes toward math and careers involving math. To measure student attitudes, a survey was administered before and after the 18-week chemistry class; results from the chemistry class were compared to survey results from students in an elective science class that did not emphasize mathematics. At the end of the 18-week period, only the chemistry students exhibited more positive views toward their abilities in mathematics and careers that involve mathematics, as compared to their views at the outset of the course. To ensure that chemistry mastery was not hindered by the additional emphasis on math, and that mastery on state end-of-course examinations reflected knowledge acquired during the math-intensive chemistry class, a chemistry progress test was administered at the start and end of the term. This exploratory study suggests that emphasizing mathematical approaches in chemistry may positively influence attitudes toward math in general, as well as foster mastery of chemistry content.     

School Chemistry vs. Chemistry in Research: An Exploratory Experiment

This report describes a study which explores, from the out-of-school student viewpoint, why students are not studying chemistry anymore. In a 2-day stay at a research institution three groups of graduating high school students from different schools, together with their chemistry teacher, were confronted hands-on with molecular modeling in industry and in university. Each of these volunteer students had agreed to write an essay on School Chemistry Vs. Chemistry in Research. These essays were evaluated together by the students, the teacher, and the researcher in a meeting at their school. The opinion of the students show that school chemistry does not convey today's chemistry in research and in industry. At the computer screen the students demonstrated their skill in performing molecular modeling experiments. Moreover, at the computer screen, chemistry was fun and easier to understand. Now we begin to see the solution: our students are also our teachers.     

The relationship between students' learning strategies and the change in their misunderstandings during a high school chemistry course

The purposes of this study are as follows: (a) to investigate the relationship between high school students' learning approaches, prior knowledge and attitudes toward chemistry, and their performance on a misunderstandings test; and (b) to describe and analyze the differences between the responses of students with different learning approaches on the same test. Forty-nine suburban high school students enrolled in two sections of New York State Regents Chemistry classes participated in the study. The students' performance on a misunderstandings pretest and the students' learning approach both accounted for a statistically significant proportion of the variance on their performance on the misunderstandings posttest. Additionally, the results showed that the relatively meaningful learners performed significantly better than the relatively rote learners on the misunderstandings posttest.     

Grade Placement of High-School Biology

Abstract

Using 35 elementary schools (3,350 fourth and sixth grade students), 10 secondary schools (3,613 eight and eleventh grade students), and 1,145 teachers, this study presents data summarizing the relationships between student' perceptions of "verified" principal competencies and selected school climate indices and outcome variables. The results indicated that there is a general tendency for positive teacher attitudes towards various dimensions of the school and working environment and higher student standardized achievement test performance to be associated with students' reports of a low frequency of interaction with die principal. A student "independence factor" was hypothesized to account for these results, with the implication being that principal/student interaction is minimized in schools where teacher and student attitudes are positive and student achievement is high. In addition, effective principal performance in dealing with student misbehavior was highly and positively associated with school average daily attendance at the secondary level. Supplementary analyses indicated that teacher and student attitudes "mediating" the school environment were relatively independent for both elementary and secondary samples. General support was found for higher correlations between student assessments of principal competencies and school environment measures than with student performance measures.     

High School‐Aged Youths' Attitudes Toward their Peers with Disabilities: the role of school and student interpersonal Factors

Negative peer attitudes are generally recognised as being a major barrier to full social inclusion at school for children and youth with disabilities. The present study examined the attitudes of 1,872 grade nine high school students in Ontario, Canada toward their peers with disabilities. A bioecological perspective and a structural equation modeling approach were adopted to investigate how various aspects of school culture and student interpersonal factors influenced attitudes. The majority of students (61%) held attitudes toward peers with disabilities that ranged from slightly above neutral to very positive. However, a substantial number (21%) held slightly below neutral to very negative attitudes. Positive student relationships at the school level and a school goal task structure that promoted learning and understanding for all students, rather than social comparison and competition among students, were two aspects of school culture that had both direct associations with positive attitudes and indirect associations through student interpersonal factors. Teacher and student relationships at the school level was an aspect of school culture that had an indirect association with positive attitudes via interpersonal support from teachers. Results support the development of ecologically based programs aimed at promoting aspects of school culture that contribute to positive attitudes of students toward their peers with disabilities.     

Inquiry-Based Laboratory Activities in Electrochemistry: High School Students’ Achievements and Attitudes

This study aimed to investigate the effects of inquiry-based laboratory activities on high school students’ understanding of electrochemistry and attitudes towards chemistry and laboratory work. The participants were 62 high school students (average age 17 years) in an urban public high school in Turkey. Students were assigned to experimental (N?=?30) and control groups (N?=?32). The experimental group was taught using inquiry-based laboratory activities developed by the researchers and the control group was instructed using traditional laboratory activities. The results of the study indicated that instruction based on inquiry-based laboratory activities caused a significantly better acquisition of scientific concepts related to electrochemistry, and produced significantly higher positive attitudes towards chemistry and laboratory. In the light of the findings, it is suggested that inquiry-based laboratory activities should be developed and applied to promote students’ understanding in chemistry subjects and to improve their positive attitudes.     

Exploring First-Year Science Students' Chemistry Self-Efficacy

First-year chemistry classes typically comprise of a mixture of majors and non-majors. Reports in the literature suggest that students have lower self-efficacy for subjects outside their intending major. Here we report on research that examines changes in chemistry students' chemistry self-efficacy throughout their first year of chemistry study at a New Zealand University. Chemistry self-efficacy was measured at three times throughout the year using the self-efficacy component of the Chemistry Attitudes and Experiences Questionnaire (CAEQ). Quantitative data were triangulated with qualitative data obtained from interviews of a cohort of 19 students. The research findings provide insights into the chemistry learning tasks that students feel high and low levels of confidence in.

Factors influencing success in introductory college chemistry

Previous research has found a wide range of predictors of student performance in introductory college chemistry. These predictors are associated with both the students' backgrounds and their high school learning experiences. The purpose of this research study was to examine the link between high school chemistry pedagogical experiences and performance in introductory college chemistry while accounting for individual educational and demographic differences. The researchers surveyed 1531 students enrolled in first‐semester introductory college chemistry courses for science and engineering majors at 12 different U.S. colleges and universities. Using multiple regression analysis, the researchers uncovered several interesting high school pedagogical experiences that appeared to be linked with varying levels of performance in college chemistry. Most notably, the researchers found that repeating chemistry labs for understanding was associated with higher student grades, whereas overemphasis on lab procedure in high school chemistry was associated with lower grades in college. These results suggest that high school teachers' pedagogical choices may have a link to future student performance. © 2005 Wiley Periodicals, Inc. J Res Sci Teach 42: 987–1012, 2005     

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.     

A Multilevel Analysis of Learning Environments and Student Attitudes

An investigation of relationships between students’ attitudes towards chemistry and their perceived laboratory environments was carried out using a sample of 1592 final year secondary school students in 56 chemistry classes in 28 randomly selected co‐educational government schools. This study is distinctive in that it marks the beginning of science classroom environment research in Singapore and because it pioneers the use of the Hierarchical Linear Model (HLM) in learning environment research. The Chemistry Laboratory Environment Inventory (CLEI), a modified version of the Science Laboratory Environment Inventory, was used to assess students’ perceptions of the learning environment in chemistry laboratory classes. Students’ chemistry‐related attitudes were assessed using the Questionnaire on Chemistry‐related Attitudes (QOCRA), which is based on the Test of Science‐related Attitudes. Environment‐attitude relationships were examined using conventional multiple regression analysis and the more rigorous HLM. Positive associations emerged between the nature of the chemistry laboratory classroom environment and the students’ attitudinal outcomes     

Perceptions of school principals about their engagement in evaluation on the basis of student data

This article describes and examines selected data on attitudes and reported behaviors of school principals associated with their engagement in student achievement data based evaluation. The data were generated from a state-wide study of elementary school principals in California. The entire study is presented elsewhere (Glasman 1986, part two, in press). This article deals with data that reflect on data utilization as a marginal tool.
