The purposes of this study were to analyse the learning environment, teacher-student interactions and educational outcomes in physical chemistry laboratory classrooms inThailand. In addition, the validation of the Chemistry Laboratory EnvironmentInventory (CLEI), the Questionnaire on Teacher Interaction (QTI) and Attitude Scale was examined. The sample was composed of 100 physical chemistry students in four Rajabhat Universities who responded to both Actual and Preferred Forms of the CLEI and QTI. Also, interviews and written stories were used with twelve students.Students' learning outcomes were investigated using a cognitive test, a practical test and the Attitude Scale. Before the questionnaires were used with the 100 students sample, the reliability and validity of the CLEI, QTI and Attitude Scale were confirmed with 198 tertiary science students in seven Rajabhat Universities. In addition, the results of students' interviews and written stories supported the validityof both the CLEI and QTI, and students improved their achievement outcomes. Thestudy found that there were differences between the students' preferred learningenvironments and what they perceived to be actually present. Associations were also found between students' perceptions of the classroom environment and student outcomes.

Process skills, such as critical thinking, communication, and problem solving, are sometimes referred to as soft skills or professional skills and have been identified by instructors and employers alike as being desirable skills for students to acquire before they graduate. The development and assessment of process skills in students were important learning objectives for both the ANA-POGIL (Analytical Process Oriented Guided Inquiry Learning) and ELIPSS (Enhancing Learning by Improving Process Skills in STEM) projects. The ANA-POGIL project consisted of a faculty consortium that was comprised of chemistry faculty. The ELIPSS project currently consists of a faculty consortium that includes representation from multiple STEM disciplines, including biology, chemistry, anatomy & physiology, math, engineering, and physics. In order to optimize the student development of process skills there should be alignment between the instructors’ goals for their courses and what they assess. The faculty members associated with both of these projects wanted to enhance students’ development of process skills by providing them with feedback, and a problem solving rubric was developed to meet those needs. The rubric categories were constructed based on faculty definitions and literature that described characteristics of successful problem solvers. To the test the rubric’s validity, it was piloted by both faculty and students. The rubric was then used in an advanced analytical instrumental laboratory course to assess the extent to which evidence of students’ process skills changed over the course of a semester. Students from the laboratory course were interviewed to gather their insights into the rubric and how they used the feedback. Findings suggest that instructors should emphasize the importance of process skills and incorporate them directly into their courses if they want students to value them. Even though students were provided regular feedback, their problem solving scores did not change appreciably throughout the semester. While students found the rubric feedback useful on the surface, they did not use the feedback in any significant way to improve on their laboratory reports because there was no grade or incentive tied to the rubrics. If faculty want students to obtain process skills, they should place some incentive on the acquisition and development of them. Another goal of the ANA-POGIL project was to develop multi-part, open-ended questions to assess process skills. To analyze evidence of the process skills that were present in the student responses, a qualitative coding scheme focused on three process skills (information processing, problem solving, and critical thinking) was used. There was overall good alignment between the process skills the faculty had identified for the exam questions and the evidence that was found in the student responses. Findings show that if instructors value eliciting a certain process skill in students’ responses, then they should be extremely explicit in how the exam structure is worded to elicit that skill. Well-designed laboratories help students develop skills in experimental design, data analysis, and communication in addition to critical technical skills. A common course structure that presents challenges for both the students and instructional staff is in upper-level undergraduate chemistry laboratories where students perform experiments in a rotational style, with each group of students working on one instrument per week. As a solution to this challenge, a set of pre-laboratory videos were generated for each experiment. Laboratory observations and student interviews were conducted to investigate how students were using the resources and to characterize their experiences in the laboratory. Findings show that students used the resources to come more prepared to complete the laboratory experiments more independently with less instructional intervention. Findings from the student observations and experiences in the laboratory show that students enjoyed working with both their peers and the instructional team to successfully complete the experiments.

Charles University in Prague - Faculty of Science Department of Teaching and Didactics of Chemistry Albertov 3, 128 40 Praha 2, Czech Republic Food in Chemistry for Chemical Education Bc. Hana Strnadová hanka.str@centrum.cz This final thesis is about using food themes in teaching chemistry at secondary level education. At first there is a brief background research made on the base of several issues focused on food chemistry. Then the conception of chemistry curricula in the Czech educational system is compared with the conception in the Slovenian educational system and the posibilities of registering the questions of food into the chemistry tuition in both countries are evaluated. Approximate analysis of several contemporary Czech and Slovenian chemistry student's textbooks for secondary schools summarises representation of this subject matter. The parts of this final work are methodically processed materials to support the experimental teaching at grammar schools.

The purpose of this study is to find out what students in the first chemistry course at the undergraduate level (general chemistry for science majors) know about the affordances of instrumentation used in the general chemistry laboratory and how their knowledge develops over time. Overall, students see the PASCO™ system as a useful and accurate measuring tool for general chemistry labs. They see the probeware as easy to use, portable, and able to interact with computers. Students find that the PASCO™ probeware system is useful in their general chemistry labs, more advanced chemistry labs, and in other science classes, and can be used in a variety of labs done in general chemistry. Students learn the affordances of the probeware through the lab manual, the laboratory teaching assistant, by trial and error, and from each other. The use of probeware systems provides lab instructors the opportunity to focus on the concepts illustrated by experiments and the opportunity to spend time discussing the results. In order to teach effectively, the instructor must know the correct name of the components involved, how to assemble and disassemble it correctly, how to troubleshoot the software, and must be able to replace broken or missing components quickly. The use of podcasts or Web-based videos should increase student understanding of affordances of the probeware.

The purpose of this study was to find out if there is a relationship between teacher-learner interactions and laboratory learning environment in Chemistry practicals in Namibia. Literatures and questionnaires from 1383 learners and 12 teachers have proven that the interactions between teacher and learners have great impact on the performance, understanding and the environment that prevail in the laboratory. The main data collection methods used was the mixed method research through the use of questionnaires and interviews. The results from the study show that good teacher-learner interactions have contributed to the positive learning environment that prevails in Namibian schools. Although the majority of the learners especially the girls have negative connotations towards Chemistry in terms of content, calculations and assessment generally learners look forward and are excited to do experiments in practical work. The impact of the excitement and willingness of learners to do practical investigations has not proven to improve learners‘ performance in Chemistry practical work in Namibia. The majority of the learners rated their teachers as good in subject knowledge, good leaders, helpful and friendly during practical investigations. The shortage of chemicals, equipments in laboratory activities that should have inspired involvement of learners in handling equipments is one of the factors that contributed negatively to the learning environment and teacher-learners interactions. Teachers mostly resolve to demonstrations due to lack of chemicals and equipment. Some schools show low/poor level of learner-learner interactions because some learners tease, laugh and discourage others during practical investigations. Chemistry laboratories in Namibia are characterised by lack of equipment, chemicals, poorly behave learners while on the other hand there are good behaviours from the teachers‘ side with most learners showing that their teachers always try to make the best out of the prevailing situations in the laboratories. The laboratory environment in Namibia closely resemble laboratory environment in other studies in Asia, Africa and Europe. From empirical evidence it can be therefore concluded that there is a relationship between teacher-learner interactions and laboratory learning environment in Chemistry practicals in Namibia. Although the relationship is not as harmonious or congruent as it ought to be, the government of Namibia can play a greater role in creating positive, productive and enjoyable learning environment by supplying secondary schools‘ laboratories with the needed equipment and chemicals to support the practical work as stated in the Physical Science syllabi. The three questionnaire used were rated by learners and teacher as effective; easy to understand; covering most areas of the Chemistry environment; not time consuming, statistically valid and consistent. The changes made to the questionnaire fit well to the Namibia Chemistry environment and it produced nearly the same reliability and validity when compared to the pilot study questionnaire and other similar questionnaires used in other country. / Curriculum and Instructional Studies / D.
