Research Guide to Mexican Law*

ABSTRACT

Carrying out effective and efficient research on Mexican law presents special challenges. Some of these are structural because they condition the entire research process. This guide covers all aspects of Mexican legal research, providing a contextualized overview of the subject. The guide is organized into three main sections: Primary Sources, Secondary Sources, and Online Resources. The reader of this guide will gain a solid foundation in how to do research on Mexican law.     

Quantifying the Effectiveness of Interactive Tutorials in Medical Library Instruction

The goal of this study was to determine whether a passive or an interactive tutorial design improves understanding of key concepts, as measured by pre- and post-test data. The authors also collected data regarding the participants' preference for taking an interactive versus a passive tutorial. The interactive tutorial group improved statistically significantly from pre-test to post-test for all three learning questions. While the passive tutorial group improved from pre-test to post-test on all three questions, the improvement was statistically significant for just two of the three questions. The majority of the participants preferred interactive tutorials (78%) to passive tutorials (22%).     

Quality and Early Field Experiences: Partnering with Junior Achievement

This study explored the perceptions of preservice teacher candidates who participated in a pilot partnership between a public teacher education preparation program and Junior Achievement (JA). The partnership was grounded in the premise that providing early field experiences to preservice teacher candidates was a necessary requirement of quality teacher education. In an introductory pedagogy course, preservice teacher candidates in their junior year participated in a five-week field experience where they taught JA lessons in partnership schools. The results suggested that preservice teacher candidates perceived an expanded sense of comfort with teaching strategies, classroom management, and diversity during the actual teaching of the lessons in the field experience. Additionally, participants reported increased confidence levels with their own preparation to teach. The partnership with JA that provided a quality, early field experience may have enhanced the general pedagogical proficiencies needed for preservice teachers to succeed as practicing educators. Suggestions for creating a partnership with JA are provided.     

Reading Instruments: Objects, Texts and Museums

Science educators, historians of science and their students often share a curiosity about historical instruments as a tangible link between past and present practices in the sciences. We less often integrate instruments into our research and pedagogy, considering artefact study as the domain of museum specialists. We argue here that scholars and teachers new to material culture can readily use artefacts to reveal rich and complex networks of narratives. We illustrate this point by describing our own lay encounter with an artefact turned over for our analysis during a week-long workshop at the Canada Science and Technology Museum. The text explains how elements as disparate as the military appearance of the instrument, the crest stamped on its body, the manipulation of its telescopes, or a luggage tag revealed the object’s scientific and political significance in different national contexts. In this way, the presence of the instrument in the classroom vividly conveyed the nature of geophysics as a field practice and an international science, and illuminated relationships between pure and applied science for early twentieth century geologists. We conclude that artefact study can be an unexpectedly powerful and accessible tool in the study of science, making visible the connections between past and present, laboratory and field, texts and instruments.     

Developing a Fine-Grained Learning Progression Framework for Carbon-Transforming Processes

Science educators have called for using the learning progression approach to align curriculum, instruction, and assessment. In line with this trend, we conducted both assessments and teaching experiments with students from grades 4 to 12 (717 students participated in the pre-assessments and 682 students participated in the post-assessments). The goal of the study is to develop a learning progression framework that provides effective guidance for curriculum and instruction on carbon-transforming processes in socio-ecological systems. We conducted the study in three research cycles. We developed a matter-and-energy learning progression framework during the first two cycles. This learning progression framework was used to guide the teaching intervention in the third research cycle. Clinical interviews and written assessments were implemented before and after the teaching intervention. In the process of data analysis, we found that the matter-and-energy learning progression framework did not provide a fine-grained depiction of students' reasoning. Therefore, we developed the five-practice learning progression framework, and used it to re-analyze data. Results indicate that the teaching intervention has helped students to achieve significant learning gains, but it was not effective enough in helping students achieve the upper anchor of the learning progression framework—constructing sophisticated scientific explanations. The results also indicate that students tended to rely on coherent and consistent reasoning to construct explanations. Based on the findings, we provide instructional suggestions and discuss the implications for climate change education and learning progression research.     

Development of an Instrument Designed to Investigate Elements of Science Students’ Metacognition,Self‐Efficacy and Learning Processes: The SEMLI‐S

The development and evaluation of science students’ metacognition, learning processes and self‐efficacy are important for improving science education. This paper reports on the development of an empirical self‐report instrument for providing a measure of students’ metacognition, self‐efficacy and constructivist science learning processes. A review of the range of literature related to metacognition, self‐regulation and constructivist learning processes resulted in the development of an initial bilingual (English and traditional Chinese) instrument composed of 72 items. This instrument was completed by 465 Hong Kong high school students. The data collected were subjected to exploratory factor analysis and Rasch analysis. The subsequent refinement process resulted in a final version of the Self‐Efficacy and Metacognition Learning Inventory—Science (SEMLI‐S) consisting of 30 items that can be used for either analysing and focusing on any or all of its dimensions or for assigning scores to individuals that enable comparison between them in relation to their metacognitive science learning orientations.     

Integrating reading and science education: On developing and evaluating WEE Science

Two studies of a new science programme called WEE Science were conducted in two fifth-grade classrooms. The studies lasted for seven days in one of the classrooms and nine days in the other. At the beginning of the programme the students chose a science trade book from among the many that were selected and brought to the classroom. The students then formed groups based on the topics of the books and asked questions (Wondering) about the content. After choosing one of the 'wonderments' to pursue further, the students formed and implemented a plan for investigating (Exploring). In each classroom, each student explored, working in cooperating groups of two or more. The students then explained (Explaining) to a group of their peers what they had wondered and what and how they had explored. The students' wonderments, activities, plans, and explanations were recorded in a science notebook that had been designed for that purpose. In addition, the classrooms were videotaped while WEE Science was in progress. While the studies were successful in that most students eagerly participated in all phases of the project, some problems were encountered which created another round of wondering for the researchers. Some of these were: evaluating students' work, responding to science misconceptions of students, teaching some students to record observations in their notebooks, deciding where WEE Science would fit best in the curriculum, and anticipating its reception in the science education community.     

Effects of Argument Scaffolding and Source Credibility on Science Text Comprehension

This study investigated the effects of argument scaffolding and source credibility on science text comprehension. Eighty-seven college students were randomly assigned to an argument scaffolding activity, or no scaffolding, and read 2 science texts, attributed to a high- or a low-credibility source. The argument-scaffolding group recalled less text-based information but generated more knowledge-based inferences than did the no-scaffolding group. High source credibility enhanced readers’ text-based recall but had little effect on knowledge-based inferences or situation models. Overall, results suggest that argumentation facilitates deeper text comprehension and better argument understanding, while at the same time reducing the effect of source credibility on text processing.
