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.     

Case‐Based Teaching: Four Experiences in Educational Software Design

Abstract

Good teaching is good story telling. Case‐based teaching exploits the basic capacity for students to learn from stories and the basic desire of teachers to tell stories that are indicative of their experiences. The premise of software that used case‐based teaching would be to place a student in a situation that the student found interesting and where the telling of a story would be appreciated. First, case‐based teachers teach the student what he or she needs to know at precisely the point of becoming interested in knowing the information. This information should be presented in the form of stories. Law schools and business schools have been teaching this way for years. They teach cases rather than rules because, by and large, they don't have rules to teach. The second critical part of learning in a case‐based environment is teaching a student to abstract from what the student has been told, and adapting it to situations for which the student was not specifically trained.

At the Institute, we have, to date, built four examples of case‐based teaching software. The programs are:

VICTOR — a voice and image courtesy tutor — built for Ameritech

DUSTIN — a language experience — built for Andersen Consulting

CREANIMATE — a biology experience‐built for schools and supported by IBM

TAXOPS — a tax opportunity advisor and cross seller — built for the Tax division of Arthur Andersen     

Factors Affecting International Students’ Decisions on Destination for Studying Abroad: A Case Study in China

This qualitative study explores how to better attract international students as perceived from the viewpoints of both international students and university administrators. The 7Ps marketing mix conceptual framework and thematic analysis were utilized to analyze qualitative data solicited from both focus group discussions involving 75 international students and in-depth interviews with four administrators at two public universities in Yunnan province, China. The results indicate that two factors mainly affect students’ decisions on an international education destination: geographical location (Place) and cost of study (Price). Furthermore, the study recommends applying the 7Ps as a totality in university recruitment practices.

Gender Gap in Mathematics and Physics in Chinese Middle Schools: A Case Study of a Beijing’s District

This study examines the gender gaps in mathematics and physics in Chinese middle schools. The data is from the Education Bureau management database which includes all middle school students who took high school entrance exam in a district of Beijing from 2006–2013. The ordinary least square model and quantile regression model are applied. This study consistently shows that the gender gap is unfavorable toward female students in mathematics and physics while favorable toward female students in Chinese and English. Gender gaps favoring males in math and physics become more noticeable among the students who receive the top tier scores in math and physics testing. However, females’ students’ advantage in Chinese and English decreases along the distribution from the bottom to the top percentiles. There are significant intersections between rural residency and gender. Rural students (regardless of gender) perform less well than urban students in all subjects and rural female student show the worst testing scores compared with the other subgroups in mathematics and physics.

A Review of “Constructing Identities in Online Communities of Practice: A Case Study of Online Learning”

ABSTRACT

This study addresses the issue of educational inadequacy and inequity for disadvantaged minority students. It estimates desired national standards and examines interrelated gaps in key school–teacher resources and mathematics achievement by linking national education data sets (National Assessment of Educational Progress [NAEP], Common Core of Data, and Schools and Staffing Survey). Although poor minority students’ chances to meet the national mathematics proficiency standard are undermined by the lack of their access to qualified teachers and adequate school funding, it turns out that the adequacy-based (absolute) gaps are much larger than the equity-based (relative) gaps. Meeting the NAEP Grade 8 mathematics proficiency standard requires substantial increases in per-pupil education spending (from $6,493 to $7,197 in year 2000 dollars) and in-field mathematics teaching rate (from 49% to 91%) across the nation. Research and policy implications are discussed.

Machine Learning–Based Profiling in Test Cheating Detection

In recent years, machine learning (ML) techniques have received more attention in detecting aberrant test-taking behaviors due to advantages when compared to traditional data forensics methods. However, defining “True Test Cheaters” is challenging—different than other fraud detection tasks such as flagging forged bank checks or credit card frauds, testing organizations are often lack of physical evidences to identify “True Test Cheaters” to train ML models. This study proposed a statistically defensible method of labeling “True Test Cheaters” in the data, demonstrated the effectiveness of using ML approaches to identify irregular statistical patterns in exam data, and established an analytical framework for evaluating and conducting real-time ML-based test data forensics. Classification accuracy and false negative/positive results are evaluated across different supervised-ML techniques. The reliability and feasibility of operationally using this approach for an IT certification exam are evaluated using real data.     

Integrating Facebook in Upper Secondary Biology Instruction: A Case Study of Students’ Situational Interest and Participation in Learning Communication

The sciences are often perceived by students as irrelevant as they do not see the content of science as related to their daily lives. Web 2.0-mediated activities are characterized by user-driven content production, collaboration, and multi-way communication. It has been proposed that employing Web 2.0 in educational activities will promote richer opportunities for making learning personally meaningful, collaborative, and socially relevant. Since Facebook is already in use among youths, it potentially provides a communicative link between educational content and students’ lives. The present study was conducted as a case study to provide an inductive, explorative investigation of whether and how the integration of Facebook into upper secondary biology can affect interest in biology and participation in learning communication. The results indicate that the coupling of formal and informal communication practices on Facebook serves to maintain interest and open up new learning possibilities while at the same time creating barriers to communication. These barriers are due to distractions, ethical issues, and a certain depreciation of the activities ensuing from the everydayness of Facebook as a communication platform. In conclusion, use of Facebook as an educational platform is not clearly good or bad.     

To Involve Parents in the Assessment of the Child in Parent–Teacher Conferences: A Case Study

This article explores the face-to-face interactions between parents and teachers in parent–teacher conferences in the Swedish preschool. The article highlights how the preschool teacher introduces the conference by using a specific artifact, so-called “strength cards” with words relating to characteristic behaviour and qualities. The theoretical framework is adopted from research of institutional talk and discourse analysis. The empirical material consists of two cases included in a larger study of parent–teacher conferences. The analysis reveals that the talk not only focuses on the assessment of the individual child but also is directed at the cards, the procedure, and the importance of parents being active and involved in learning the procedure. In addition, the cards are used by the teacher as a tool that governs parents towards becoming ‘good enough preschool parents’ who are cooperative and able to categorise and label their own children, that is, follow the institutional discourse. The analysis also shows that parents take control in order to overcome institutional barriers to parents’ involvement.     

Programmed Learning in Engineering Education?A Preliminary Study

A recent study of programmed learning, including experimental use in an electrical engineering department, indicated that the most fruitful application of teaching machine methods is in the presently nonprogrammed or loosely programmed hours spent by students outside classroom or laboratory periods. Programs already developed for use in this study have been concerned with analytical skills; further programs under development are concerned with concepts. Larger scale experiments are planned in which additional questions can be answered, particularly as to whether exposure to programmed instruction adversely affects the capacity of the student to learn independently.

Developing ‘Butterfly Warriors’: a Case Study of Science for Citizenship

Given worldwide concern about a decline in student engagement in school science and an increasing call for science for citizenship in New Zealand Curriculum, this study focused on a butterfly unit that investigated how students in a year-4 primary classroom learnt about New Zealand butterflies through thinking, talking, and acting as citizen scientists. The butterfly unit included five lessons. The researchers observed the lessons and interviewed students and the classroom teacher. The students completed a unit evaluation survey after the unit. Findings indicate that the students enjoyed and were interested in activities such as reading about butterflies, learning and using new vocabulary, drawing butterfly life cycles, as well as hunting, tagging and releasing butterflies and publishing the data they had collected on a dedicated website. Through their participation in the unit, students had opportunities to act locally and globally, and to ‘see themselves’ in science through ‘being there’ experience. Units like this have the potential to develop students’ interest for longer-term engagement in science, even those students who may never envision themselves as professional scientists.

Learning Computer Graphics Using Virtual Reality Technologies Based on Constructivism – Case Study of the WebDeGrator System

This study applies constructivist principles and Virtual Reality (VR) technology to the Web-based Interactive Design Graphics (WebDeGrator) system to improve learning computer graphics. The constructivist treatment provides students with access to their choice of source content, three-dimensional (3D) modeling tools and interactive behaviors in a virtual environment. In this study, we developed a VR-based learning system to simulate and adjust computer graphics through sculpture graphic algorithms in real-time. We will discuss the relationship between constructivism and VR technology and also how the WebDeGrator system encourages student-learning through VR technology.     

Measuring Elementary Student’s Mathematics Motivation: A Validity Study

The psychometric properties of a 10-item math motivation scale were empirically validated with an independent sample consisting of 182 elementary-school students. Analysis of the model dimensionality supported a one-factor structure fit. Item parameter estimates from a Classical Test Theory framework revealed that most items were highly discriminating, and the survey is informative for students of low to average math motivation. Differential item functioning (DIF) analyses found two items exhibiting gender bias. Overall, the instrument was a psychometrically valid instrument for measuring math motivation at the elementary level.
