The Impact

STEM education programs are often formulated with a "hands-on activities" focus across a wide array of topics from robotics to rockets to ecology. Traditionally, the impact of these programs is based on surveys of youth on program-specific experiences or the youths’ interest and impressions of science in general. In this manuscript, we offer a new approach to analyzing science programming design and youth participant impact. The conceptual framework discussed here concentrates on the organization and analysis of common learning activities and instructional strategies. We establish instrument validity and reliability through an analysis of validity threats and pilot study results. We conclude by using this instrument in an example analysis of a STEM education program.

The Impact

The Scientific Teaching (ST) pedagogical framework provides various approaches for science instructors to teach in a way that more closely emulates how science is practiced by actively and inclusively engaging students in their own learning and by making instructional decisions based on student performance data. Fully understanding the impact of ST requires having mechanisms to quantify its implementation. While many useful instruments exist to document teaching practices, these instruments only partially align with the range of practices specified by ST, as described in a recently published taxonomy. Here, we describe the development, validation, and implementation of the Measurement Instrument for Scientific Teaching (MIST), a survey derived from the ST taxonomy and designed to gauge the frequencies of ST practices in undergraduate science courses. MIST showed acceptable validity and reliability based on results from 7767 students in 87 courses at nine institutions. We used factor analyses to identify eight subcategories of ST practices and used these categories to develop a short version of the instrument amenable to joint administration with other research instruments. We further discuss how MIST can be used by instructors, departments, researchers, and professional development programs to quantify and track changes in ST practices.

Pengaruh Karakteristik Perusahaan Terhadap Keefektifan Sistem Informasi Ditinjau dari Dimensi Kualitas PelayananMeasurement of information system effectiveness from service quality dimension has become an issue in MIS area. Researchers argue about the use of service quality (servqual) instrument to measure the information system effectiveness. Several studies indicate that service quality associates with company size and organization structure. This study intends to reexamine servqual instrument validity and reliability. Further more, this study attempts to measure information system effectiveness from service quality dimension and to investigate the impact of company size and organization structure on service quality. Item to total correlation, split-half method, and path analysis are used to test reliability of the instrument. Servqual instrument validity is tested by comparing servqual instrument items with in the framework of management information system theory. Wilcoxon test is used to test information system effectiveness by comparing the expected and perceived quality measurements. To measure the impact of company size and organization structure on service quality, a regression model is estimated. The data is collected with survey method. Questionnaire is sent to marketing managers, finance managers, human resources managers, and research and development managers as research subjects. The research is based on 82 valid responses. The result shows that, in general, servqual instrument is stastically reliable and valid as a measuring instrument. The result of information system effectiveness test from service quality dimension shows that there is a difference between manager’s perceived and expected service quality. Study result also shows that service quality is not influenced by company size and organization structure. Unlike previous studies, this study reinvestigates validity and reliability of the servqual instrument regardless of industry types and it attempts to investigate the impact of company size and organization structure on service quality.

The Impact

Purpose – The purpose of this paper is to explore the concept of supply chain quality management (SCQM) and to propose a research model that considers the impact of SCQM practices on firm performance. Design/methodology/approach – Based on a comprehensive literature review, SCQM most relevant practices were analyzed and selected. These practices were categorized into four dimensions: upstream (supplier assessment, supplier quality management (QM)), downstream sides of a supply chain (customer focus), internal process (product/service design, process management and logistics) and support practices (top management support, human resource management, information and supply chain integration). The measurement instrument of firm performance was also developed, including three aspects: operational performance, customer satisfaction and financial performance. Findings – An innovative conceptual framework that provides a comprehensive picture covering core dimensions of SCQM and various aspects of firm performance was proposed. This conceptual framework can be used as “a guideline” for theory building and measurement instrument development of SCQM and firm performance. More importantly, on the road to gain a further insight, an extensive structural model that identifies direct and indirect relationships between SCQM and firm performance was also developed. Practitioners/managers can apply this model as “a road map” for implementing SCQM practices. Research limitations/implications – It is necessary to test the rationality of these models by using empirical studies in different contexts. Originality/value – The integration of quality and supply chain management still remains limited in the literature. Therefore, it is necessary to have a more focussed approach in assessing QM issues within the internal and external supply chain contexts. This study concentrates on the practices which improve quality aspects of the supply chain, known as SCQM practices. Proposed research models in this paper not only fill out the voids in the literature, but also contribute with conceptual frameworks for theory building in SCQM and firm performance. The authors also expect that this research can offer a useful guidance for measuring and implementing SCQM practices as well as facilitate further studies in this field.

The Impact

Millennial generation employees are employees who value flexibility in their work. Therefore, work-life balance is one of the factors that can affect the attitude of millennial employees in the company. Job satisfaction is an employee's perspective on his work to see how far the company has met employee expectations. A work-life balance makes employees feel job satisfaction because they can work well while in the office; therefore they do not need to be burdened with problems outside of work. In addition, good quality of work-life balance will increase employee retention so that the company can avoid problems related to employee retention. This research aimed to explore the effect of work-life balance on job satisfaction and employee retention of the millennial generation employees in the city of Bandung, Indonesia. The sample used in this study was 196 employees from various fields of work. Analysis of data used simple linear regression, by testing the quality of the data through validity and reliability test. Study results found that there was an effect of work-life balance on job satisfaction as much as 8.3%, and there was an effect of work-life balance on employee retention of 4.4%. One of the managerial implications of the research results that can be implemented is organization should provide a good work environment and facilities to increase the motivation of the employees.

The Impact

This study focuses on examining the impact of three components of materialism on green purchase intention for urban consumers in Vietnam, an emerging economy. An extended Theory of Planned Behavior (TPB) is applied as the conceptual framework for this study. The hypotheses are empirically tested using survey data obtained from consumers in Hanoi, the capital of Vietnam. The regression results show support for most of our hypotheses. The findings indicate that two out of three facets of materialism are significant predictors of green purchase intention. Specifically, success is found to be negatively related to purchase intention, while happiness is related positively to the intention. All three antecedents in the TPB model, including attitude towards green purchase, subjective norm, and perceived behavioral control are also found to have positive impacts on purchase intention. The research findings are discussed and implications for managers and policy makers are provided.
